Through-hole is provided with, the height of middle cylinder upper end is located between absorption chamber upper end and middle cylinder lower end, and outlet is connected on the outside of absorption chamber upper end
Pipe, absorption chamber middle part outside are connected with overflow pipe, and air outlet pipe height is higher than middle cylinder upper end and overflow pipe height, and the air outlet pipe is led to
Piping is connected with wind turbine, and air outlet pipe is respectively provided at the both sides of absorption chamber with overflow pipe,
The axis on the absorption tower, air funnel and middle cylinder overlaps.
Preferably, the air funnel bottom is connected with overflow screen.
Preferably, it is connected with overflow screen between the middle cylinder upper end and air funnel.
Preferably, the absorption chamber bottom outside is connected with outlet tube.
The beneficial effects of the invention are as follows：
Exhaust gas enters absorption chamber from air funnel, and the gap between air funnel and middle cylinder moves upwards, finally from outlet
Pipe is discharged, and annular space structure can increase the contact area between gas and solution, improves absorption efficiency, gas in annular space with it is molten
Liquid cocurrent, pressure drop is small, and resistance is small, and the gas far from air outlet pipe side can flow to form circulation to air outlet pipe side, compared to drum
The time of contact for steeping absorption tower gas and solution is longer, and reaction is more abundant, and assimilation effect is more preferable.

Specific embodiment
In order to which those skilled in the art is made to more fully understand technical scheme of the present invention, below in conjunction with the accompanying drawings and most
The present invention is described in further detail for good embodiment.
As shown in the figure, the present invention includes：Absorption tower 1 and in absorption tower in the air funnel 2 that is vertically arranged and penetrates through,
Baffle 3 is welded between absorption tower in the middle part of the air funnel, baffle plays the role of air funnel support, and
Absorption tower is divided into inlet plenum 4 and absorption chamber 5 by baffle,
The inlet plenum top middle portion is connected with air inlet pipe 6, also inserted with inlet tube 7 and blowdown pipe 8, tonifying Qi in inlet plenum
Pipe lower end height between air funnel upper end and inlet tube lower end,
The absorption chamber bottom is welded with middle cylinder 9, and the middle cylinder is set between absorption tower and air funnel, middle cylinder bottom outside
Through-hole 10 is provided with, the height of middle cylinder upper end is located between absorption chamber upper end and middle cylinder lower end, is connected with out on the outside of absorption chamber upper end
Tracheae 11, outside is connected with overflow pipe 12 in the middle part of absorption chamber, and air outlet pipe height is higher than middle cylinder upper end and overflow pipe height, it is described go out
Tracheae is connected with wind turbine 13 by pipeline, and purified gas is sucked out, while can promote to give up from absorption tower by wind turbine
Gas preferably enters absorption chamber and flows, and is reacted with solution, air outlet pipe is respectively provided at the both sides of absorption chamber, this reality with overflow pipe
When applying the exhaust gas in example and being moved in annular space, since the gas close to air outlet pipe side can be discharged from air outlet pipe faster, far
The gas for separating out tracheae side can be to movement at air outlet pipe, so as to form circulation, principle and Airlift circulating reactor principle
It is identical, it can make that exhaust gas and reacting for solution are more abundant, and assimilation effect is more preferable,
The axis on the absorption tower, air funnel and middle cylinder overlaps, and makes exhaust gas distribution more uniform, is fully reacted with solution.
Absorption plant in the present embodiment injects solution into absorption tower when in use, from inlet tube, liquid level in inlet plenum
Raising covers inlet tube and blowdown pipe lower end, is flowed into absorption chamber through air funnel, and liquid level raising is until from overflow pipe in absorption chamber
Outflow, exhaust gas enters inlet plenum from air inlet pipe, enters absorption chamber through air funnel under pressure, air funnel in the present embodiment
Bottom is connected with overflow screen 14, and exhaust gas becomes bubble along the upward cocurrent in gap between air funnel and middle cylinder by overflow screen
It moving, bubble breaking after liquid level in arrival absorption chamber, purified gas is discharged from air outlet pipe, in order to improve assimilation effect, this
