In figure, 1 is tower body, and 2 be VOCs gas entrances, and 3 be upper strata deflector, and 4 be VOCs gas communicating pipes, and 5 be hypomere ceramics Packing layer, 6 be hypomere spraying layer, and 7 be hypomere absorbing liquid mouth, and 8 be epimere spraying layer, and 9 be epimere packing layer, and 10 absorb for epimere Liquid mouth, 11 be clean gas outlet, and 12 be hollow cone nozzle, and 13 be demister.

Embodiment

In order to which technical problem to be solved in the utility model, technical solution and beneficial effect is more clearly understood, with Lower combination accompanying drawings and embodiments, are further elaborated the utility model.It is it should be appreciated that described herein specific real Example is applied only to explain the utility model, is not used to limit the utility model.

As shown in Figure 1 and Figure 2, VOCs gas showers absorption tower, including tower body 1, the bottom of tower body 1 are equipped with VOCs gas entrances 2, the middle part of tower body 1 is provided tiltedly with upper strata deflector 3, and tower body 1 is divided into upper strata deflector 3 hypomere treatment region and epimere is handled Area, is interconnected between epimere treatment region and hypomere treatment region by VOCs gas communicating pipes 4；

Hypomere ceramic packing layer 5 and hypomere spraying layer 6 are equipped with hypomere treatment region, hypomere spraying layer 6 is located at hypomere ceramics The top of packing layer 5, the bottom of tower body 1 are equipped with hypomere absorbing liquid mouth 7, epimere packing layer 9 and epimere are equipped with epimere treatment region Spraying layer 8, epimere spraying layer 8 are located at the top of epimere packing layer 9, and the tower body 1 that the low spot of upper strata deflector 3 goes out is equipped with epimere Absorbing liquid mouth 10, the top of tower body 1 are equipped with clean gas outlet 11.

In use, VOCs gases everywhere are collected by pipeline and are pumped by wind turbine to the spray absorber uniformly added. VOCs gas enters inside tower body 1 from VOCs gas entrance 2, first passes around hypomere ceramic packing layer 5 and removes large granular impurity, under The absorbing liquid counter current contacting that the gas of section ceramic packing layer 5 is from bottom to top sprayed with hypomere spraying layer 6, fully absorbs pollutant Absorbing liquid is exported from hypomere absorbing liquid and discharged, and is entered by the VOCs gas for absorbing pollutant by VOCs gas communicating pipes 4 on tower body 1 Section treatment region.Into epimere treatment region gas again by epimere ceramic packing layer check on remove impurity, filled out by epimere ceramics The absorbing liquid counter current contacting that the gas of the bed of material is from bottom to top sprayed with epimere spraying layer 8, fully absorb the absorbing liquid of pollutant from Epimere absorbing liquid outlet discharge, from clean gas outlet 11 after the purified gas of absorption pollutant removes droplet by demister 13 Discharge tower body 1.Since VOCs gases successively pass through spray-absorption twice in tower, gas liquid interfacial area can be effectively increased, is improved Spray-absorption efficiency, the pollution gas such as the tar in VOCs gas, benzene, ammonia, hydrogen sulfide are effectively removed, and are allowed to row up to standard Put.

At least two layers of deflector type demister 13 is also installed on absorption tower top, passes through absorber portion to VOCs gas after isolation of purified When entrained with droplet, prevent " to rain " phenomenon generation.

In addition, in order to ensure spray-absorption effect, some hollow cones are housed on hypomere spraying layer 6 and epimere spraying layer 8 Nozzle 12, arrangement ensure to spray being uniformly distributed for drop to be evenly arranged.

The utility model uses circular configuration, its tower body 1 takes up an area less, and investment is low.Hypomere spraying layer 6 and epimere spraying layer 8 Upper that some hollow cone nozzles are housed, arrangement ensures to spray being uniformly distributed for drop to be evenly arranged, and improves spray-absorption Efficiency, the pollution gas such as the tar in VOCs gas, benzene, ammonia, hydrogen sulfide are effectively removed, are allowed to qualified discharge.Absorb Two layers of deflector type demister 13 is also installed on tower top, the droplet of entrained with when passing through absorber portion to VOCs gas after isolation of purified, Prevent phenomenon generation of " raining ".

Described the embodiments of the utility model have been described in detail above with reference to the accompanying drawings, but the utility model and unlimited In above-described embodiment, within the knowledge of a person skilled in the art, the utility model can also not departed from Various changes can be made on the premise of objective.
