Description

A kind of injection turbulent contact absorber
Technical field
The present invention relates to a kind of injection turbulent contact absorber, belong to flue gases purification field.
Background technology
Absorption tower is the equipment for realizing absorption operation.It is divided into three classes by the gas-liquid form that is in contact.The first kind is gas with gas Steep scattered plate column, bubble absorbing tower, the stirring bubble absorbing tower in the liquid phase of form;Second class is that liquid is disperseed with droplet-like Injector, spray tower in the gas phase;3rd class is that liquid moves the packed absorber contacted with gas phase and drop with membranaceous Film absorption tower.In tower the type of flow of gas-liquid two-phase can adverse current also can cocurrent.Generally use counter-current operation, absorbent is with tower top Addition is flowed from top to bottom, is contacted with the gas flowed from bottom to top, and the liquid for absorbing absorbent is discharged from bottom of towe, after purification Gas from tower top discharge.So flue gas and liquid to be sufficiently mixed to the filtering that can promote flue gas in absorption tower, improve and inhale Receive the clean-up effect of tower.
The content of the invention
It is an object of the present invention to provide a kind of injection turbulent contact absorber, flue gas and drop can be filled in absorption tower Divide mixing, so as to improve the clean-up effect on absorption tower.
In order to solve the above technical problems, the present invention adopts the following technical scheme that:
A kind of injection turbulent contact absorber, including absorption tower body, the top of absorption tower body have gas approach and flue gas Outlet, the intrinsic top in absorption tower have dividing plate, and gas approach is located at the side of dividing plate, and exhanst gas outlet is located at the another of dividing plate Side;The top of absorption tower body is separated into separate inlet flue duct and exhaust pass by dividing plate, is provided with and draws in inlet flue duct Turbulator is penetrated, the lower section of dividing plate has gas-liquid separation pond;Homogenizing plate, spraying layer and demister, demister are provided with exhaust pass Positioned at the top of spraying layer, spraying layer is located at the top of homogenizing plate.
In a kind of foregoing injection turbulent contact absorber, injection turbulator is made up of distribution webmaster, nozzle and Venturi tube, point Lower section with webmaster connects some nozzles, and the lower section of each nozzle is provided with a Venturi tube.
In a kind of foregoing injection turbulent contact absorber, Venturi tube is by the inlet tube, trunnion and anemostat group that are sequentially communicated Into.
In a kind of foregoing injection turbulent contact absorber, the quantity of spraying layer is more than or equal to 2.
