EVALED RV N How the unit works


How does it work? Technology

10

Diagram

a) Energy saving technology based on the mechanical vapor compression MVR

b) Heat transfer with vertical

tubes and natural circulation of the internal fluid based on the different density of the ww in the pipes and boiling chamber.

c) RV N evaporator operates in

batch wise mode: • Complete emptying at the end

of the cycle • Refilling at start of a new cycle


How does it work? Start up phase

Start up phase: 1. Blower start-up and

creates vacuum 2. The waste is pumped

through the main heat exchanger to the boiling chamber

3. At minimum level reached, liquid is heated by means of resistors until the evaporation condition and produce vapor

4. Blower and evaporation process start at steady state


12

How does it work? Evaporation

Evaporation: 1. Efficient heat recovery

from the distillate through the secondary heat exchanger

2. Evaporation heat recovered into main heat exchanger from vapor condensing on shell side

3. WW pumped into the boiling chamber (controlled by level sensor)

4. Production of vapor and drop separation (distillate quality)


How does it work? Distillate circulation

Distillate circulation: 1. Vapor compression by the

blower and temperature rising 2. Latent heat release into main

heat exchanger and condensation

3. Passage through secondary heat exchanger and cooling

4. Collection in a tank and discharge through a pump


How does it work? Concentrate discharge

Concentrate discharge: 1. Recirculation within boiler

and main heat exchanger by natural circulation

2. Discharge at reaching of the set concentration (PLC)

3. Automatic discharge by pneumatic pump



Optional: Configuration and optional


RV N: Configuration and optional

CONFIGURATION OPTIONS • BLOWER: cast iron/stainless steel • Electrical panel: air conditioned/not air conditioned

OPTIONAL/ACCESORIES

Carry-over corrosion potential

Installation site

solution storing

- Valves group on skid for

preparation of cleaning

solution 1.1 x 0.6 x 1.2 (h) m

3 x 1.1 x 1.5 (h) m


Optional: automatic chemical washing system

Washing cycle:

1. Process liquid emptying

2. Filling of evaporator’s boiler and heat exchangers

with cleaning solutions coming the storage tanks

3. Circulation of the cleaning solution (by the same

concentrate discharging pump)

4. Evaporator emptying, transfer back of cleaning

solution to tanks by same pump

5. Step 2 to 4 repeated for second cleaning solution

Timing: washing in 1-1.5 hours

RV N stop and start in about 2-3 hours


Remote control: service support

Requirement:

• Installation of Optional Remote Control

device (OI RC)

• Internet connection (via VPN or ADSL/WiFi/UMTS)

What the optional device can give:

• protect access by password to the unit

PLC from wherever

Annual cost (300 working days) : about 144.000 €/y

Opex cost

Available energy: EE 0.06 (€/kWh)

Opex: about 7 €/ton (0.03 $/gal)

Annual OPEX cost : about 11.340€

Separation: 5.4 tons/day water reuse

Concentrate disposal cost: 80 €/ton ( 0.36 $/gal)

Concentrate annual disposal cost: = about 14.400 €

Saving: 144.000 – 11.340 - 14.400 = 118.260 €/y
