Area, the bottom in the liquid removal area are provided with air inlet, and the bottom in the dry removing area is provided with exhaust outlet, and described liquid takes off
Except the taper screen cloth to be raised up in area provided with multiple tracks, mouth connection is communicated with the top of liquid removal area and dries removing area, is done
The top in dry removing area is provided with airflow-distribution board, and multiple air-flow shower nozzles are evenly distributed with below airflow-distribution board, dry removing
The middle part in area is provided with solid adsorbed layer, and Electrocontrolled tee valve is connected with below solid adsorbed layer, and Electrocontrolled tee valve is provided with backflow
Mouth and gas outlet, described refluxing opening are connected to the bottom in liquid removal area, described gas outlet connection exhaust outlet.
As a modification of the present invention, agitating shaft and multiple agitating paddles, monolithic cone are provided with described liquid removal area
The lower section of shape screen cloth is provided with an agitating paddle；Pass through the multiple stirring paddle structures being connected on single agitating shaft, layering stirring liquid
Liquids and gases in body removing area so that gas is uniformly distributed in liquid, facilitates the abundant removing of sour gas.
As a modification of the present invention, adsorption stuffing, solid packing layer top are filled with described solid packing layer
Provided with multiple hollow air flow method grooves, described air flow method groove is arranged on the underface of air-flow shower nozzle；Pass through air-flow shower nozzle
Gas is uniformly ejected into solid packing layer, by that will be sprayed with the one-to-one air flow method groove of air-flow shower nozzle, convenience
Air-flow be uniformly distributed in adsorption stuffing, facilitate fully contacting for air-flow and adsorption stuffing.
As a modification of the present invention, the setting height(from bottom) of described taper screen cloth is less than connected entrance；Taper screen cloth is used for
Be uniformly distributed the bubble risen in liquid removal area, it is convenient that gas is evenly dispersed in liquid removal area, facilitate gas with
The abundant contact of liquid.
Movable sealing lid is provided with as a modification of the present invention, above described housing, in described movable sealing lid
Provided with driving motor；The structure that device generally seals, by movable sealing lid structure, convenient maintenance and maintenance.
The advantage of the invention is that：The present invention changes gas in liquid medium by the gas removal plants after improvement
In distribution mode, stir and the double action of taper screen cloth under, improve the contact area of gas and liquid, it is convenient acid
Gas fully absorbs；It is more in convenient absorption gas by the way that gas is uniformly blown into solid sorbent filler after the completion of absorption
Remaining steam and other impurities, finally collect and detected below solid packing, enter subsequent operation system after up to standard, fill
It is simple in construction to put itself, control is accurate.
