The type and typical pollutant of pollutant have hydro carbons (benzene,toluene,xylene, n-hexane, naphtha, hexamethylene, methyl cyclohexane
Alkane, dioxane, diluent, gasoline), halogenated hydrocarbons (trichloro ethylene, perchloroethylene, trichloro ethylene, dichloromethane, trichlorine
Methane, carbon tetrachloride, freon class), aldehydes (formaldehyde, acetaldehyde, methacrylaldehyde, furfural), ketone (acetone, MEK, cyclohexanone,
MIKB), esters (ethyl acetate, butyl acetate, ethyl oleate), alcohols (methanol, ethyl alcohol, isopropanol, n-butanol, isobutanol),
Polymer monomer (vinyl chloride, acrylic acid, styrene, vinyl acetate), amides (dimethylformamide, acetic acid dimethylamide), nitrile,
Cyanogen class, hydrogen cyanide and acrylonitrile etc..Currently, VOCSAdministering method mainly have physical method (absorption, absorb, condensation, at film
Reason), chemical method (burning, biodegradable, photocatalytic degradation) and the united method of the two.Relative maturity on treatment technology, but
How to utilize these technologies to high-efficiency low energy consumption, then it is crucial to be that the design aspect of processing equipment or system makes innovation.
Utility model content
In order to solve the above problem of the prior art, the utility model offer one kind is simple in structure, low energy consumption and can be efficient
Remove the device of VOC in industrial tail gas.
The utility model use main technical schemes include：
The device of VOC in a kind of removal industrial tail gas comprising：
There is air inlet and gas outlet, the air inlet to be inhaled set on the VOCs for the absorption towers VOCs, the absorption towers VOCs
Tower lower end is received, the gas outlet is set to the absorption towers VOCs upper end, and the absorption towers VOCs are set as purifying from bottom to top successively
Solution tank, first order sprayer, separate filtering layer, second level sprayer, condenser, stainless steel demister；
Exhaust conveying air hose, exhaust conveying air hose one end connect the gas outlet on the absorption towers VOCs, the exhaust
Convey the detachably connected oxidation pipeline section of the air hose other end；The oxidation inner tube segment is equipped with more and connects with ozone generator
The gas distribution pipe connect, the gas distribution pipe are equipped with stomata and in the height direction interval stacking arrangement；
There is air intake and exhaust outlet, the air intake to connect the oxidation pipeline section, the row for adsorption tanks, the adsorption tanks
Gas port connects exhaust chimney, is covered with the baffle plate of active carbon layer in the adsorption tanks equipped with surface, and the baffle plate will be described
The inside of adsorption tanks is separated into S-shaped gas flow.
Preferably, water or alkaline solution are loaded in the purified solution slot, the purified solution slot connects a cycle
Pump, the circulating pump connect reservoir, and the reservoir connects the first order sprayer and second level sprayer.
Preferably, filter membrane is equipped between the purified solution slot and the circulating pump.
Preferably, the separate filtering layer is PE filter plates.PE filter plates are with UHMW-PE ultra-high molecular weight polyethylene powder

Better dissolubility.Reservoir 82 is with delivery pump (not painting) connection first order sprayer 221 and second level sprayer 222, and first
Water or dilute alkaline solution can be refined into tiny water mist or droplet by grade sprayer 221 and second season sprayer 222, thus and exhaust gas
Contact area with bigger, improve dissolving exhaust gas in sour gas molecule, esters speed.
Separate filtering layer 23 is preferably a kind of PE filter plates.PE filter plates are with UHMW-PE ultra-high molecular weight polyethylene powder
The filter medium being sintered for raw material by setting technique has excellent acid resistance high temperature resistant and high filtering precision, is easy to regenerate
Etc. performances.By separate filtering layer 23, by some undissolved escaping gas and dissolving but with the solution droplet of air-flow rising
It is retained down Deng by separate filtering layer 23.
Condenser 24 is made of Multi-layer supporting plate 241 and several reducing pipes 242 being embedded in support plate 241.Subtract
The draw 242 is in generally horn-like, and one end is relatively large in diameter the smaller tubular structure of other end diameter, the one end being relatively large in diameter downward,
Upward, in this way, when air-flow passes through reducing pipe 242, air-flow is contracted by the compression of pipe 242 and temperature is caused to drop the smaller one end of diameter
It is low.
Stainless steel demister 25, including multilayer stainless steel plate, is 4 layers of stainless steel plate, every layer of stainless steel plate table as shown in Figure 1
Face is equipped with slit shape elongated hole, and slit-type elongated hole is width 0.12mm~0.3mm* length 6mm~8mm, and density of setting is every
Square centimeter setting 8-12, these slit-type elongated holes are formed by laser cutting technique.Gas and droplet etc. are by this
When a little slit-type elongated holes, it can be forced to form very thin air-flow film, the droplet in air-flow film remains stuck on stainless steel.
After condensed device 24, stainless steel demister 25, almost VOC gas are absorbed with what air-flow rose by whole
Solution water integument is trapped in the absorption towers VOCs 20, ensures the gas dry degree of gas outlet 202.
Exhaust conveying air hose 30 connects the gas outlet 202 on the absorption towers VOCs 20, and exhaust conveying air hose 30 is equipped with first flange
