Yet further, the spraying layer is made up of multiple atomizers.
The beneficial effects of the utility model are：Current-sharing module is provided with multiple apertures, before turbulent gas into devices,
Entering gas by current equalizer, aftertreatment device mobility is more stable, and reaction is more abundant, and then the best of it
Manage effect.Spherical ceramic packing specific area is big, and strong adsorption force, more for handling the waste gas such as benzene,toluene,xylene, stench
Secondary treatment by stages reaches processing highest standard, and guarantee reaches discharge standard.A plurality of serpentine channel is provided with demisting layer when aqueous
Gas gas enters inside demister, encounters wall in the serpentine channel of complications, vapor adhesion in being accumulated to constant weight above,
Bottom is flowed to along demisting dividing plate under gravity to be collected, and then the effect of demisting, it can equally reach
The effect of even air-flow.Provided with the first desulfurization layer and the second desulfurization layer, the further sulfide adsorbed in waste gas, pretreatment module
In be provided with multiple hollow-fibre membranes, waste gas can be prevented the advance filtration treatment of the impurity of big particle diameter thick by hollow-fibre membrane
Bulky grain is deposited in water, adds equipment loss during wastewater treatment.Collecting pit is provided with below equipment, can be by the molten of absorption
Liquid and water droplet are concentrated through delivery port discharge, and concentration is drained into sewage treatment equipment to be handled again.Observation window can facilitate
Staff checks filler state, can change and clear up in time after adsorption saturation.
Brief description of the drawings
Fig. 1 is external structure schematic diagram of the present utility model；
Fig. 2 is pretreatment module perspective view.
Mark explanation：Air inlet 1, air outlet 2, the first desulfurization layer 3, the second desulfurization layer 4, demisting layer 5, spraying layer 6, flow
Module 7, pretreatment module 8, filler 9, observation window 10, collecting pit 11, delivery port 12, water pump 13, pharmacy jar 14, hollow-fibre membrane

Embodiment
Embodiment of the present utility model is described in further detail below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, waste gas is entered in equipment by air inlet 1, by current-sharing module 7, is set in current-sharing module 7
There are multiple airflow holes, before turbulent gas into devices, gas is entered aftertreatment device mobility by current equalizer
More stable, reaction is more abundant, and then optimization process effect.Waste gas enters pretreatment module after passing through current-sharing module 7
8, pretreatment module 8 is interior to be provided with multiple hollow-fibre membranes 15, and gas must be by that could enter first after hollow-fibre membrane 15
The material of big particle diameter is filtered, prevents big particle to be deposited in water, add wastewater treatment by desulfurization layer 3, hollow-fibre membrane 15
When equipment loss, subsequent waste gas enter after just considering in the first desulfurization layer 3, and water pump 13 is run, by the hydrogen in pharmacy jar 14
