Description

Combined type acid-fume absorber

Technical field

The utility model is related to a kind of combined type acid-fume absorbers, are mainly used for absorbing the acid mist of hydrochloric acid receiver discharge.

Background technology

At present, hydrochloric acid is stored in access point by the receiver of closing, when supplementing hydrochloric acid to receiver, is transported in tank car Hydrochloric acid entered in receiver by unload acid pump, while in receiver gas discharge.The gas of receiver discharge is acid mist, There is strong sharp aroma and highly corrosive.In order to ensure environmental protection, safety, acid mist cannot be directly discharged into air, need to set Absorption plant is put to be handled.Old-fashioned acid-fume absorber is water spray acid mist, through polyhedron empty ball packing material absorbing heel row into In waste liquid pool, manual operation is needed；Also have and receiver fog exhaust pipe is inserted directly into the bucket equipped with treatment fluid, mended in receiver Fill hydrochloric acid complete, need from receiver take hydrochloric acid when, reservoir pot liquid reduce generate negative pressure, needing will be at fog exhaust pipe extraction Liquid liquid level is managed, treatment fluid is avoided to be inhaled into receiver.These existing absorption plants be primarily present it is cumbersome, using very It is inconvenient, lead to the problem of acid waste water, extremely not environmentally.

Utility model content

The technical problem to be solved by the utility model is to provide a kind of combined type acid-fume absorbers easy to use.

The technical solution of the utility model is as follows：A kind of combined type acid-fume absorber, the tank body including closing, in the tank Frog-entering pipe is fitted at the top of body, the lower end of the frog-entering pipe is stretched into bottom in tank body, is also equipped at least at the top of the tank body Two exhaust pipes, the lower end of each exhaust pipe are connected with tank inner chamber, between each exhaust pipe and frog-entering pipe Branch pipe is communicated with, the position that the branch pipe is connected with frog-entering pipe is located at outside tank body, is mounted on each branch pipe only The check valve that can be connected from exhaust pipe to frog-entering pipe is additionally provided with inlet on the tank body top, is equipped in the tank body lower part Sewage draining exit.

Using the above structure, receiver discharge acid mist when, check valve is turned off, acid mist from frog-entering pipe enter tank bottom and to On seethe, come into full contact with and react with the treatment fluid in tank body, finally discharge clean gas from exhaust pipe；In receiver salt When acid is drawn, receiver and frog-entering pipe generate negative pressure, and under the action of negative pressure, all check valves are opened, and air is arranged certainly Tracheae enters frog-entering pipe and into receiver, so as to offset negative pressure in time, the treatment fluid in tank body is avoided to flow backwards and enters receiver It is interior.In this way by more exhaust pipes, more branch pipes and multiple check valves, negative pressure is timely responded, passes through answering for structure Design is closed, makes acid mist absorption and negative pressure counteracting are automatic to realize, does not need in addition provide power, it is not required that it is hand-manipulated, make With it is very convenient, operating cost is low.In actual use, lye may be used as treatment fluid, the discharge capacity of waste water is low, Ke Yijie About great lot of water resources.Also, the branch pipe that air importing is carried out to frog-entering pipe is directly connect with exhaust pipe, has effectively saved sky Between, make whole structure compacter, occupied space smaller.

Lateral gas distribution pipe is connected in the lower end of the frog-entering pipe, connect and leads in the middle part of the frog-entering pipe and gas distribution pipe It is logical, multiple holes have been evenly arranged on the gas distribution pipe.Gas distribution pipe and uniformly distributed hole are conducive to the equal of acid mist and treatment fluid It is even to come into full contact with, be conducive to improve the absorption efficiency of acid mist, in fact, using this structure, the absorptivity of hydrochloric acid is high in acid mist Up to 98%.

Preferably, there are two the exhaust pipe is symmetrically arranged, the branch pipe and check valve also correspond arrangement There are two.

Hagioscope is installed on the tank body top, the hagioscope is closed by transparent panel.Convenient for being observed by hagioscope Standard liquid level of the hagioscope height as treatment fluid can also be used in the depth and state for the treatment of fluid in tank body, convenient for by treatment fluid Addition standardization.

Overflow port, the overflow port and hagioscope be arranged at an equal altitude are additionally provided on the tank body top.It is automatic convenient for treatment fluid It overflows, avoids treatment fluid in tank body excessive.

The lower tank of the tank body including upper end opening and the cover by the closing of lower tank opening, the frog-entering pipe, exhaust pipe and Inlet is respectively positioned in cover, and the overflow port and hagioscope are located at the top of lower pot sidewall, and the sewage draining exit is located at lower tank bottom Portion.The structure of tank body is simple, production is easy, assembly manipulation is simple.

Advantageous effect：The utility model on the tank body of closing by inserting frog-entering pipe, at least two exhaust pipes of setting, branch Pipe and check valve avoid treatment fluid in tank body from flowing backwards, so as to provide a kind of combined type acid-fume absorber, make acid by check valve Mist absorbs and negative pressure offsets automatic realization, does not need to manual operations, more convenient to use.
