Description

Alkali liquor absorption tower Technical Field The utility model relates to the technical field of chemical equipment, in particular to an alkali liquor absorption tower. Background The absorption tower is equipment for realizing absorption operation, and is divided into three types according to gas-liquid phase contact modes. The first type is a plate column, a bubbling absorption column and a stirring bubbling absorption column in which gas is dispersed in a liquid phase in the form of bubbles, the second type is an ejector, a venturi tube and a spray column in which liquid is dispersed in a gas phase in the form of liquid drops, and the third type is a packed absorption column and a falling film absorption column in which liquid is contacted with the gas phase in a film-like motion. The working principle of the alkali liquor absorption tower mainly comprises gas-liquid contact, acid component absorption, reaction product separation, liquid regeneration, cyclic utilization and the like. At present, after the alkali liquor absorption tower runs for a long time, sediment is generated at the bottom of the tower, and a sewage pipeline at a sewage disposal position is often blocked due to long-term sediment accumulation and solidification. And the alkali liquor absorption tower has the problems of waste of alkali liquor and low utilization rate of the alkali liquor due to insufficient acid-base reaction in the neutralization reaction process. Disclosure of utility model The utility model aims to solve the problem that a sewage drain pipe is often blocked in the prior art by inventing an alkali liquor absorption device aiming at the defects of the prior art. In order to achieve the above purpose, the present utility model adopts the following technical scheme: An alkali liquor absorption tower comprises a tower body, wherein the tower body comprises a tower interior and a tower exterior, a spraying device is arranged at the top of the tower interior and comprises a spray head and a spray pipe, the spray head is detachably connected with the spray pipe, a liquid inlet pipeline is arranged at the bottom of the tower interior, and the liquid inlet pipeline penetrates through the tower body from inside to outside and is connected with an alkali liquor tank for supplying alkali liquor. Further, a branch pipe is arranged on the liquid inlet pipeline and is communicated with the liquid spraying pipe to supply alkali liquor to the spraying device.
