Fig. 2 is the work sketch map of the utility model embodiment two;
Fig. 3 is the instance graph of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
As shown in Figure 3 is the utility model instance graph, cooperates illustrated in figures 1 and 2ly, and the spraying lacquer organic exhaust gas that the utility model discloses reclaims and filters controlling device, comprises wadding filter 2, sack cleaner (or cloth tube deduster) 3, absorber 5 and condenser 6.It is cotton to be provided with thick effect fiber filter in the wadding filter 2, the import of wadding filter 2 with collect organic exhaust gas pipeline (or paint spray booth, drying room) and be connected the air inlet of the outlet connection sack cleaner 3 of wadding filter 2; The gas outlet of sack cleaner 3 is connected to the inlet of blower fan 4; The outlet of blower fan 4 is connected to the air inlet of absorber 5, and the gas outlet of absorber 5 and atmosphere offer the desorption liquid inlet on the absorber 5; The desorption liquid inlet of absorber 5 is connected with the steam pipeline; The water supply steam gets into, and through steam being fed in the absorber 5, organic solvent desorption adsorbed in the absorber 5 is come out; The desorption liquid outlet of absorber 5 is connected to the inlet of condenser 6, and the outlet of condenser 6 is connected to the inlet of oil water separator or solvent liquid storage tank.
In the present embodiment; Bulky grain, the viscosity coating cloud of thick effect fiber filter cotton in the wadding filter 2 in can filtering exhaust; Also can contain in the wadding filter 2 spaces such as labyrinth flap 21 or wire packing big, cross the strong material of wind energy power, hold the thing ability of removing with increase.The filter bag of sack cleaner 3 can adopt fiber cloth bag or fibrofelt cloth bag, also can adopt cloth tube deduster.Blower fan 4 can be arranged on (as shown in Figure 2) before the sack cleaner, also can be arranged on (as shown in Figure 1) after the sack cleaner, can also be after absorber.Absorber 5 can adopt active carbon adsorber, also can adopt compound charcoal bed adsorber or carbon fiber adsorption and catalytic combustion device, also can adopt molecular sieve adsorber.Have an absorber 5 in the utility model at least, the concrete number of absorber 5 and connected mode are according to actual needs and design and decide.Condenser 6 can be water-cooled or air-cooled.
First road filtration of the utility model is that the principle of wadding filter 2 mainly adopts filler to filter; Thereby the waste gas bulky grain in the waste gas, coating cloud with viscosity through the pre-treatment filter time are sticked to the purpose that reaches removal on the filler of filter; Filler adopts thick fiber filter cotton or the ripple packing of imitating simultaneously; Have the dust suction capacity big, cross the little characteristics of wind resistance, thereby more be applicable to the coating cloud pre-treatment of slow curing paint.This case and cyclone dust collectors all are in order to remove bulky grain, the viscosity coating cloud in the waste gas; Difference is that cyclone dust collectors do not need the filler loss; But windage is bigger, and this case wadding filter 2 windages are little, and is better to the removal effect of sticky particle; But filtering material need be changed filtering material along with the increase windage of filtration yield also increases when being increased to a certain degree.This case is to removing viscosity coating cloud particle better effects if.
As shown in Figure 1, be that the used spraying lacquer of the utility model organic waste-gas purification reclaims filtration controlling device embodiment one work sketch map, concrete steps are following:
(1) organic exhaust gas that production line comes out is coated with lacquer in spraying; After collecting or coming out from paint spray booth, the drying room 1 that sprays paint; Carry out filtration treatment through wadding filter 2, after the harmful substances, particularly stickum to active carbon such as the most of dust in the removal waste gas, coating cloud; Get into sack cleaner 3, remove the fine dust that front filter can't be tackled;
(2) waste gas is through wadding filter 2 and sack cleaner 3 post processings; After coating cloud, dust are removed totally basically; Only contain volatile organic matter (organic solvent) in the waste gas; After this waste gas was pumped the volatile organic matter (organic solvent) that gets in the absorber 5 absorption waste gas by high pressure positive blower 4 again, waste gas is purified handled discharging, has reached the purification purpose;
(3) absorber 5 absorption saturated after; Adopt water vapour that adsorbent is carried out desorption and regeneration; Become liquid after volatile organic matter that desorption comes out (solvent) and 6 condensations of water vapour process condenser, send into separator or storage tank and wait to separate the back reuse of purifying, reached the purpose that reclaims organic solvent.
As shown in Figure 2, be that the used spraying of the utility model lacquer organic waste-gas purification reclaims and filters controlling device embodiment two work sketch mapes, the difference of itself and Fig. 1 is that blower fan 4 also can be placed on before the sack cleaner 3.
The utility model spraying lacquer organic exhaust gas reclaims and filters controlling device, focuses on the basis of existing technology, and waste gas through wadding filter 2, is removed most of big dust particle and viscosity coating cloud earlier.Still contain more micron-sized dust through the lacquer of the spraying behind the wadding filter 2 waste gas, these dust are very big to follow-up adsorbent effect on service life, for this reason; The utility model especially to the lacquer spraying waste gas characteristics, adopts the higher sack cleaner 3 of filtering accuracy; Pass through sack cleaner 3 again; More fully remove particle dust,, thereby to adapt to the not contaminated prolongation of the characteristics assurance adsorbent adsorbent service life of the big Dust Capacity of spraying lacquer waste gas.Wadding filter 2 adopted fiber filter material or the ripple packing that wind resistance is little, dust containing capacity is big, to adapt to the waste gas demand of big air quantity.Wadding filter 2 also can contain the labyrinth flap, and retaining removes the bigger particle of a part of particle diameter, to alleviate the filter dust quantity of pre-treatment filtering material.Simultaneously, sack cleaner 3 can adopt rapping or anti-blow cleaning dust method, the maintenance workload of alleviator.
Two embodiment that the above is merely the utility model are not the restriction to this case design, and all equivalent variations of doing according to the design key of this case all fall into the protection domain of this case.
