Specific embodiment

The technical solution of the utility model, but the protection scope of the utility model are described in further detail with reference to the accompanying drawing It is not limited to as described below.

In embodiment 1, this emission-control equipment is for carrying out the coating cloud being collected into paint spray booth in paint line Processing, i.e. air inlet 3 are used to receive coating cloud in paint spray booth, and the air after processed at exhaust outlet 4 can be directly discharged to outer Portion or the fresh air being provided in paint spray booth.

As shown in Figure 1, the integrated circular formula emission-control equipment in a kind of paint line, including treating column 1 and follow Ring water tank 2, the lower end of the treating column 1 are provided with air inlet 3, and basket strainer 18 is additionally provided with inside the air inlet, place The top of reason tower is provided with exhaust outlet 4, and the bottom plate for the treatment of column 1 is connect by circulation line 5 with cyclic water tank 2.

Wherein, treating column 1 is mainly used for handling the exhaust gas (coating cloud) for entering the present apparatus, and cyclic water tank 2 is used for Collect the collection and recycling of the water after the spray for the treatment of column 1.

To avoid having from the exhaust gas to be processed of air inlet 3 certain dust, it is arranged at the air inlet in the present embodiment There is the basket strainer 18 for completely cutting off external dust.

It is detailed in Fig. 1,2 bottom of cyclic water tank is provided with water circulating pump 6, is connected with portion on the water circulating pump 6 Divide the water pipeline 7 penetrated inside treating column 1, the water spray end of the water pipeline 7 is provided with several spray heads 8, the spray The height of waterpipe 7 is higher than air inlet 3.

For spraying this part, in initial situation, there is a certain amount of water inside cyclic water tank 2；When the present apparatus is opened It (paints start in the paint spray booth of position in the present embodiment) after beginning work, the water circulating pump 6 inside cyclic water tank 2 pumps water to water spray Pipeline 7, and further sprayed water to the exhaust gas entered in treating column 1 by spray head 8, the coating cloud in exhaust gas can lead at this time It crosses the water mist that spray head 8 sprays out to be adsorbed, and is entered in cyclic water tank 2 by circulation line 5 under gravity, circulation Water tank 2 also has the function of deposition.

As shown in Figure 1, the upper V-type being additionally provided with from the bottom to top above water pipeline 7 inside the treating column 1 is inhaled Water separates net 9, lamp bracket 10 and photocatalyst plate 17, and the ultraviolet lamp 11 of multiple parallel connections is provided on the lamp bracket 10.

Wherein, lamp bracket 10 and photocatalyst plate 17 are used to carry out photocatalysis and first pass around the exhaust gas of spray adsorption treatment to moving up It is dynamic, due to being absorbed water by upper V-type and separating the absorption that net 9 carries out aqueous vapor just through that can have a part of moisture after spray, it Exhaust gas after drying afterwards is degraded by ultraviolet lamp 11, and dry by generating under the action of photochemical catalyst on photocatalyst plate 17 Net free of contamination gas, is emitted into outside for the clean free of contamination gas after the completion of processing finally by exhaust outlet 4 or mentions It is supplied in paint spray booth.

Also, in the present embodiment, the material of V-type water suction partition net 9 is SAP (Super Absorbent Polymer), The material is a kind of new functional macromolecule material.It has the function of the several hundred high water absorptions to thousands of times of water of absorptance itself weight, And water retention property is excellent, when water swelling becomes hydrogel, water is difficult to separate pressurization.High-hydroscopicity Resin is a kind of functional high molecule material with a large amount of hydrophilic radicals.

As shown in Figure 1, the circulation line 5 includes vertical end 12, horizontal end 13 and interconnecting piece 14, described is perpendicular The one end in straight end portion 12 and one end of horizontal end 13 are connected by interconnecting piece 14, the other end connection of the vertical end 12 The other end for the treatment of column 1, the horizontal end 13 connects cyclic water tank 2；The vertical end 12 inside by up to Under be disposed with fine sand filter layer 15, activated carbon filter layer 16.

Wherein, if being not provided with fine sand filter layer 15 and activated carbon filter layer 16, can to spray after a number of uses The water mist of journey can also have a large amount of coating cloud, so that adsorption capacity reduces.That is, fine sand filter layer 15, active carbon filter Layer 16 is to further increase the utilization rate of recirculated water for purifying to the water mist of the formation after spray.

Wherein, fine sand filter layer 15 can further filter the fine particulates not filtered out in basket strainer, simultaneously Since the leakproofness of fine sand filter layer is preferable, the exhaust gas into treating column 1 is not easy to go out from this across hence into cyclic water tank 2, That is fine sand filter layer 15 also has the function of that a resistance value exhaust gas is flowed to cyclic water tank 2.

And active carbon is black powder or bulk, graininess, cellular amorphous carbon, also there is the crystal of arranged regular Carbon.In active carbon in addition to carbon, also include two class admixtures: one kind is chemically combined element, mainly oxygen and hydrogen, these Element be due to not completely charing and remain in charcoal, or in activation process, external non-carbon element and activated carbon surface Chemical bonding；Another kind of admixture is ash content, it is the inorganic part of active carbon, and ash content easily causes secondary dirt in activated carbon Dye.Active carbon produces, in life due to being widely used in stronger adsorptivity.Industrial air purification activated carbon have with Lower advantage: 1. long service life, adsorption/desorption Reusability；2. high adsorption and desorption property, to greatly improve returning for solvent Yield；3. high-intensitive low ash part, pore-size distribution are reasonable；4. cost performance is high, this place is suitble to have organic gas recycling；5. Ignition point height uses safe to ethers, ketone, alcohols, tetrahydrofuran, methylene chloride, chloroform, trichloro ethylene, crosses chloroethene The organic solvents such as alkene, carbon disulfide, benzene, toluene, formyl, gasoline, hydrochlorofluorocar,ons and organic steam have very strong separation, recycling Performance.The high intensity of wooden column-shaped active carbon is using non-adherent pressed active carbon proprietary technology.It is free of binder composition, complete The special nature of full affinity and raw material itself between charcoal molecule.Scientific formula is made, and effectively avoids charcoal hole stifled Plug gives full play to the adsorption function in abundant flourishing charcoal hole.Bigger serface, mesoporous are flourishing.It organises since paint belongs to Work high molecular material is formed by film and belongs to high-molecular compound type, and therefore, in the present embodiment, active carbon is formed Activated carbon filter layer 16 can paint the part in water mist and adsorb.
