Abstract
The utility model discloses environment-friendly equipment, in particular to a high-concentration acid-base tail gas treatment device. A static mixer is arranged at the upper part of an absorption liquid tank, a venturi tube is arranged at the upper part of the static mixer. An outlet of a circulating pump is connected with an absorption liquid cooling tank by a pipeline. A working method of the high-concentration acid-base tail gas treatment device comprises the steps: during the working of the circulating pump, absorption liquid circulates to produce negative pressure and absorb the acid-base tail gas in a tail gas buffering tank, the static mixer sends the absorbed acid-base tail gas into the absorption liquid tank so as to enable the absorbed acid-base tail gas to directly enter the absorption liquid, and the absorbed acid-base tail gas is discharged from a gas outlet after being treated by the absorption liquid. The high-concentration acid-base tail gas treatment device is simple in structure and reasonable in design. The venture tube and the absorption liquid tank are arranged, so that the tail gas to be treated can directly enter the absorption liquid for treating, and no tail gas at dead corners can be hidden. Therefore, the tail gas can be treated and absorbed cleanly and thoroughly. The treated tail gas can entirely achieve the emission standard. The problems of the existing equipment can be solved.
Description
Technical field
What the utility model was announced is environmental protection equipment, specifically a kind of controlling device of high concentration soda acid tail gas.
Background technology
For protection of the environment better, all to administer the tail gas of discharging at some chemical enterprises at present, to reach discharge standard.The improvement of existing high concentration soda acid tail gas generally adopts the method for absorption tower spray to carry out, but its treatment effect is undesirable.After soda acid tail gas enters the absorption tower, because the treatment fluid that spray equipment sprays can not form continuous phase, consequently a part of tail gas can not touch treatment fluid and run away, and the gas at dead angle can escape the spray for the treatment of fluid too and can not get processing in tower to also have part to hide.Thereby do not reach discharge standard.
Summary of the invention
For above-mentioned situation, the purpose of this utility model provides the treating apparatus of the good soda acid tail gas of a kind for the treatment of effect, solves the problem that existing equipment exists.
The utility model is to address the above problem the technical scheme of taking to be: consist of by absorbing liquid bath, Venturi tube and static mixer.On the top that absorbs liquid bath with static mixer, on the top of static mixer with Venturi tube.Absorbing on the side of liquid bath with overfall.In absorbing liquid bath with dividing plate.Being low concentration region in the inboard of dividing plate, is high concentration region at the opposite side of dividing plate.At absorption liquid bath top one gas outlet is arranged.At the gas outlet sidepiece with fresh absorption liquid import.At the sidepiece that absorbs liquid bath one circulating pump is arranged.On circulating-pump outlet, connect by the road an absorption liquid cooling bath.In the bottom that absorbs liquid bath one feed liquid loop exit is arranged.Method of work of the present utility model is: under circulating pump work, absorption liquid is sucked out from absorbing liquid bath, send into the absorption liquid cooling bath, enter again Venturi tube and get back to the absorption liquid bath, produce negative pressure when passing through Venturi tube in the circulation, the soda acid tail gas in the tail gas buffer is sucked, tail gas is admitted to the absorption liquid bath through static mixer, directly enter in the absorption liquid, after absorption liquid is processed, discharge from the gas outlet.The utility model is simple in structure, reasonable in design.Owing to Venturi tube and absorption liquid bath, processed tail gas directly entered in the absorption liquid processed, do not have the dead angle to hide for partial tail gas.Therefore process absorb thoroughly clean.Tail gas reaches discharge standard fully after processing.Solved the problem that existing equipment exists.
