- When disposing of spare parts which have been in contact with the dust to be filtered, inparticular filter media, the operator has to take care that this will be done in accordancewith any Local regulations that apply for the type of dust concerned.

- When operating the filters the operator must ensure that no inflammable objects, such ascigarettes, cigars, sparks or other inflammable materials, such as paper, cardboard, clean-ing rags, plastics or other wastes can inflame the filter sleeves. Otherwise the filters haveto be equipped in addition by the operator with appropriate fire protection devices,consulting, however, the fire protection experts.

- The filters, which are provided, are only to be used for the collection of dusts from the types

of gases which are stated in our contract specification "Technical Data". If the filters areused on other dusts and gases, then the filters will fall outside our warranty terms, and theoperator must carry sole responsibility for risks resulting from this use. Filters of standardexecution must never be operated with combustible or explosive dusts and gases. For thistype of use the filters must be of special design and construction and fitted with specialexplosion protecting devices.

2.4 Additional safety instructions at inflammable dusts

2.4.1 General instructions

a) Inflammable dusts are:

-fire hazardous in quiescent condition

-explosion hazardous in whirled-up condition.

b) In case of inflammable dusts the filters have to be equipped with safety devices against

dustexplosions. The electric devices are also included here.

2.4.2 Dust explosion and fire protection

The operator has to take care that no ignition sources from other areas could lead into thefilter

Examples for potential ignition sources are:

- Hot surfaces

- Flames and hot gasses

- Sparks and glowing nests- Sparks generated mechanically

- Welding and cutting

- Spontaneous ignition

- Electrical recources

- static electricity

- Thunderbolt

People who work in areas where there is a risk of explosions should not be dangerouslycharged. Through the respective conductive protective clothing and floors, charges can be

avoided.- If there is danger of dust burnings the operator has to check-up whether the local condi-

tions will be sufficient for a necessary fire extinction (qualified staff, works fire station, localfire station).

- For the design of explosion- and fire protection equipment for the filters special knowledgewill be necessary. These safety devices must therefore not be revised without havingofficial authority.

- If this protection equipment against dust explosions and dust fires will not or not completelybe ordered together with the filters with Messrs. FILTRES INTENSIVand be required fordelivery the operator has to take care for the completeness of this equipment.

2.4.3 List condition (Division in zones)

The filter is in accordance with category 3 and can be used in areas with explosive dusts.

The following zone-concept for the filter was based on in accordance with EN 1127.

2 inside filter-Clean gas chamber Zone 22

3 outside the filter: Zone 22 (in the periphery of 1m)Additional electrical or not electrical pieces of equipment must be suitable for the respectivezone.


10/70



Model IFJC-R


2.4.4 Protective concept against explosion

1 The stability of the filter is designed for a reduced explosion pressure in connection withpressure relief at atmospheric pressure.

Flames and pressure waves caused by an explosion will be transmitted in connected pipelines and components and could cause severe damage there.

It must be insured that explosions in a filter do not lead to any secondary explosions withimpermissibly high pressures.

The filter unit is only to be used with suitable components in thedirty gas or the clean gas line as well as in the discharge area..If this is not done, the chance of deadly explosions can not beexcluded.

In the case of a fire or an explosion the filter, including all dischargeorgans and topped dust transportation ways, fan, filter cleaningsystem, etc. must be put out of operation immediately to avoid anydust clouds and transfer of inflammable materials into adjacentcomponents. (Use signal e.g. by bursting sensor of the bursting diskor response signal of the decoupling systems and/or by the fireprotection system for triggering)

Model IFJC-R


The sleeve-round filters are equipped with a fully automatically operated filter sleevecleaning system. The cleaning of the filter sleeves is effected by pulses of compressed airor other pressure gases together with secondary air by means of a 2-stage injector system.During this process the cleaning air flow is blown via the inlet nozzle (6) into the filter sleeves(3) causing a sudden reversal of pressure opposite to that of the filtration flow in the cleaningair flow.

Figure 9: Filter sleeve section (cleaning phase)

Due to this sudden change in pressure, the filter sleeve which took up the shape of a stararound its support cage is suddenly inflated into a circle and the reverse flow of cleaning air

blows the dust off the outer surface of the filter sleeves which falls into the dust collectionhopper.

The operation of the filter sleeve cleaning has to be supervised byregular checkings!

3.9 Filter sleeves

Figure 10: Filter sleeve

The filter sleevces are designated by the following data:

- nominal diameter "D"

- nominal length "L"

- type of material

- other (e.g. special details regarding manufacture - due to the individual manufacturenecessary for each type of material the stated dimensions of the filter sleeves may not beabsolutely identical to the finished sizes.)


20/70



Model IFJC-R


The filter sleeve material quality is of decisive importance to the function of the filter and isselected according to each individual application.

The ruling factors are:

-Type of dust, dirty gas composition and grain distribution in the raw gas flow.

- Plant- or process technique of the plant to be dedusted.

- Required residual dust values in the clean gas.

The following may be detrimental to the function of the sleeve-round filter:

- incorrect selection of the filter material- incorrect or inexpert manufacture

- poor storage facilities

- damage due to inexpert storage or installation.

When using other filter sleeves which do not correspond to the FILTRES INTENSIV originalexecution there is the risk of injuries to health to the personnel working in the influencingarea due to an insufficient exhaust capacity of the filter plant, or due to exceeding the legallydetermined admissible residual dust values in the clean gas.

Only filter sleeves which correspond to the original execution of NTENSIV have to be used!

Pay attention to the exhaust capacity of the sleeve-round filter!Pay attention to the admissible residual dust values in the clean gas!

24/70



Model IFJC-R


Stage 1

Compressed air is fed into the circular cavity (4) of the "Coanda" injector (1) via the injectortube (2) and escapes through the circular slot (5) causing an axial stream (6) down the insidesurface of the injector. This induces secondary air (7) into the injector (1).

Stage 2

This combined compressed air and secondary air leaves the injector (1) and enters the inletnozzle (11) at high speed inducing a further supply of secondary air (9). This total reverseair flow causes a sudden inflation of the filter sleeves (12) which blows the accumulated dust

from its outer surface.

3.14 Sealings

Figure 17: Sealings

The good function of the filter depends mainly from the sealing. For sealing of the filter flatsealings will be used (see sketch). Sealing points which are not shown have to be treatedsimilarly.

3.15 Inspection openings

All inspection- and maintenance openings at the sleeve-round filters in the area of dustconveying equipment, such as dust rotary valves and flaps, are provided with haxagon

screws thus preventing that one can get into movable machine parts involuntarily. Theselockings can only be opened by means of corresponding tool. (wrench). When openingvoluntarily it is presumed that the corresponding plant part will be switched-off. Thus thesleeve-round filter plants have therefore only to be operated with tightened openings.

Should for the operators works other safety philosophies and prescriptions or additionalwarnings be applicable these should be considered by the operator at the sleeve-round filteroperation.

Sleeve-Round Filters must only be operated with tightenedopenings!

There is the risk of danger due to movable machine parts!

Before opening the inspection door in the crude gas area, switch offthe drives for the discharge parts as well as the heating for thehousing and let them cool off for 15 minutes.

If this is not done, dust fires or explosions due to ignition by hotsurfaces cannot be excluded.

1.2 Function

Figure 2: Diagram of the filter sleeve cleaning

The function of the electric control of the filter sleeve cleaning will be determined by thefollowing times:

- pulse time

- cycle time (interval time)

- cleaning cycle

The following times are preset by standard:

- pulse time (electrical): 50 ms

- cleaning cycle: 120 s


31/70



Model IFJC-R


The cleaning cycle has to be understood such that the filter sleeve rows will be cleaned eachone at an interval of 120 s.

The clock time (interval time) can be established as follows:

e.g.: filters with 3 filter sleeve rows

cleaning cycle 120 sclock time = ------------------------------------ = --------- = 40 s

number of sleeve rows 3

filters with 5 filter sleeve rows

cleaning cycle 120 sclock time = ------------------------------------ = --------- = 24 snumber of sleeve rows 5

filters with 5 filter sleeve rows

cleaning cycle 120 sclock time = ------------------------------------ = --------- = 12 s

number of sleeve rows 10

In case of bigger filters the number of the cleaned filter sleeve rows will be distributed to the10existing connections of the control unit so that in these cases one or more sleeve rowswill be cleaned in parallel. The cleaning cycle of 120 s will, however, also be maintainedhere. The clock-time, and thus also the cleaning cycle, can be adjusted on request to thelocal conditions, considering, however, the resulting consequences. These settings assume

professional knowledge and should only be done after having consulted the experts of themanufacturer. In case of a modification of the cleaning cycle the following should beconsidered:

a) Shortening of the cycle time

- the compressed air consumption increases in the same ratio

- cleaning of the filter sleeves will be more intensive

b) Prolongation of the clock time

- the compressed air consumption decreases in the same ratio

- the efficiency of the cleaning decreases also according to the local conditions

The pulse time is set in the control unit and sealed up. This setting may not be modified,-in special cases only by experts-.The use of various types of control units is possible.

A separate operating instruction has to be considered.

1.3 Electrical connections

The sleeve-round filters will be supplied completely wired. All cables have identificationnumbers. The customer has to install the electronic control unit. An easily accessible placeshould be chosen for the place of installation. If possible, the control unit should not beinstalled at the filter, since due to the shaking of the pneumatic cleaning system the functioncan be affected. The connection to the valve- resp. terminal boxes arranged at the sleeve-round filter and the current supply of the control unit has to be installed by the customer.

To ensure the correct function of the sleeve-round filters it is necessary to provide the

electric connections according to the terminal plans pertaining to each individual filter type.All electric works must only be effected by qualified personnel according to the DIN / VDEstandards as well as to the local conditions.Modifying the pulse- and clock times without having official authority may endanger thecorrect function of the filter plant and must only be effected - if at all -only by the technicalexpert personnel.Filter plants with electric installation in normal execution may not be operated in hazardouslocations and critical against vapours or dusts. For these purposes other types of electricinstallations with special protection types are necessary.

Model IFJC-R


The necessary compressed air for the filter sleeve cleaning will be supplied by:

- works network (10)

- compressors (8).

A compressed air set (5) is provided before each sleeve-round filter (1).

This air set meets the following functions:

- separation and filtration of dirty particles, oil and water with automatic drainage

- regulation of the adjusted cleaning pressure.

The cleaning pressure to be adjusted can be taken from the point "Technical Data".If the pressure in the supply line (7) will be higher than the admissible pressure in thecompressed air reservoir (2), the compressed air system of the filter has to be protected bya safety valve (6). A shut-off valve (3) is provided at each compressed air reservoir (2)between the distributing main (4) and the compressed air reservoirs (2) in order toepressurize the compressed air reservoir when effecting e.g. repair-or control works.The main shut-off valves (9 or 11) permit a switch-off of the total compressed air system.The sections of the supply lines (7) provided by the customer have to be chosen big enough(in case of short supply lines one nominal width bigger than the connection at the compres-sed air set). At longer supply lines the sections of the same have to be adjusted to the localconditions. The condensate arising obligatorily at the compressor plant will be let off by the

compressor drainage (12).As to the compressor itself the operation instruction of the manufacturer has to beconsidered.

6 Maintenance

Avoid sparks with all repairs!

6.1 Protective measures during maintenance work

For maintenance work where there is a risk of ignition in areas at riskof explosion or in areas where the work can result in a dangerousexplosive atmosphere arising, protective measures are necessary.

The employer or their representative must specify the location, start,duration and extent of the necessary protective measures in workinstructions, usually in writing and must instruct the employeesaccordingly (for the coordination of work see paragraph 6 of theregulations for the prevention of industrial accidents "Generalregulations" (German employers' liability insurance associationregulations BGV A1)).

Work may only start when the employer or their representative has

ensured that the protective measures have been carried out and areeffective. The effectiveness of the protective measures must bemonitored for the duration of the work. The employer or theirrepresentative may only cancel the protective measures when themaintenance work has been completed and there is no longer anydanger.

After the maintenance work is complete it must be ensured that theexplosion protection necessary for normal operation is effectivebefore operation is restarted.

Coordinating workpara. 6

(1) If an employer subcontracts work to another company then, ifnecessary to avoid being a danger to one another, the employermust nominate someone to be responsible for the coordination ofthe work. The employer must ensure that this person has authorityover the subcontractor and their employees..

(2) If the subcontractor accepts jobs which are to be done at thesame time and place as jobs to be done by other subcontractors,then they are obliged to coordinate with the other subcontractors asfar as is necessary to avoid presenting a danger to one another.

Model IFJC-R


6.9.2 Removal of the filter sleeves

The removal of the filter sleeves will be effected in the reverse sequence. Before removalthe filter cleaning should be switched-in for such a long period until the filter sleeves are freefrom dust. In certain cases, e.g. in case of dust types which are dangerous to health orexcessive heat it can be advantageous to let the fan of the filter plant operate in throttledstate. The thus penetrating fresh air through the sleeve bottom holes creates a betteratmosphere for the personnel. Useless filter sleeves have to be disposed according to thelocal conditions considering the legal prescriptions.

When changing the filter sleeves only the filter sleeve quality has tobe used which has been designed for the dust to be filtered!Accident preventing prescriptions have to be considered carefully!If required by the local prescriptions protecting clothes have to beused!Breathing masks have to be used in general!The prescriptions for disposal of filter sleeves which can no more beused have to be paid attention to!
