The surface raffinate of the electrostatic kitchen fumes purification assembly of clear water continuous flushing of 8 outflows.
The time of clear water rinsing is 20min.
Step 4: drying electrostatic kitchen fumes purification assembly.
Electrostatic kitchen fumes purification assembly after clear water is rinsed is transferred to drying tank 9 from clear water potcher 7;Then,
By the way of sweeping electric infrared heating with wind, the electrostatic kitchen fumes purification assembly of flash baking;Finally, stop heating, to
After electrostatic kitchen fumes purification assembly is cooling, electrostatic kitchen fumes purification assembly is taken out from drying tank 9 it is spare, thus complete
At the entire cleaning process of electrostatic kitchen fumes purification assembly.
Electricity 10 heating temperature of infrared heating body is 60 DEG C, and 11 swing flap wind speed of small-sized fan is 5m/s, and drying time is
20min。
Electrostatic kitchen fumes purification assembly maintenance: correcting linear discharge electrode position and restores individual earthing pole cylinders because touching
It the depressed area caused by reasons such as hits, guarantees system high efficiency, stabilization, longtime running.
Step 5: cleaning solution post-processes.
Firstly, bulk in cleaning solution will fall off or graininess deposit is pulled out, and it is put into special barrel and carries out at concentration
Reason;Then, treatment agent is added in the cleaning solution for having pulled blocky or graininess deposit out and is handled;Finally, opening super
Sound rinse bath Inlet and outlet water valve 13, by treated, cleaning solution is discharged into sewerage.
The treatment agent is the combination of bleaching powder and ferric trichloride, and the weight ratio of bleaching powder and ferric trichloride is 1:1.
For certain large enterprise employee dining room (exhaust gas volumn 15000m3/ h) electrostatic kitchen fumes purification assembly carry out
Cleaning treatment.Electrostatic kitchen fumes purification assembly after cleaning is returned and is filled to purification system, to the testing result of oil smoke processing
Show: before cleaning, oil smoke and particulate matter removal efficiencies are respectively 70% and 63%, and oil smoke and granular material discharged concentration are respectively
12mg/m3And 6.1mg/m3;After cleaning, the removal efficiency of oil smoke and particulate matter is respectively 98% and 89%.Export oil smoke and
Grain object concentration is respectively 0.8mg/m3And 1.8mg/m3。
