Description
Technical field
The utility model relates to the bromine preparation field, relate in particular to a kind of in the bromine packaging process retracting device of tail gas.
Background technology
Bromine packing is last procedure of system bromine, generally makes the bromine industry and directly the product bromine is installed in the pottery bottle of 30kg/ bottle and store as ready.There is the high concentration of enterprises of minority output to be stored in the enamel pot, and then divides and to install in the pottery bottle or directly be filled on the enamel pot haulage vehicle.Because of bromine is a kind of volatile liquid, no matter take any manner of packing packing or can, the pipeline expose portion all contains bromine vapor and evaporate in the air, not only causes the waste of bromine, and surrounding environment is caused severe contamination.This gas is sucked by the people, can be to the calcination of human body respiration organ, and serious consequently people suffocates, if elegant in the middle of flowers, plants and trees, can be to its quick calcination, therefore very withered dying must administer it, to cut the waste and to protect environment.
In traditional technological operation, the bromine vapor that bromine volatilizees in the packing all is employed in the bromine porch and adds an air blast, adds exhaust duct with blower export, high altitude discharge.Though this device is protected the operator, but still can not solve the wasting of resources and environmental pollution.
The utility model content
The technical problem that the utility model will solve provides and a kind ofly reduces the bromine wasting of resources, is beneficial to environmental protection, guarantees the bromine packing device for recovering tail gas that human body is healthy and safe.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:

The utility model bromine packing device for recovering tail gas; The bromine tail gas that volatilizees in the packaging process gets in the mist eliminator through exhaust collection cover, air blast; In mist eliminator, spray absorption liquid, bromine tail gas is absorbed liquid and absorbs, and the absorption liquid behind the absorption bromine flows in the absorption tower.The utility model is simple in structure, and is easy to operate, reclaimed more completely and evaporate into airborne bromine vapor in the packaging process; Solved the evaporating, emitting, dripping or leaking of liquid or gas on the baling line fully; Reduce the waste of bromine resource, reduced environmental pollution, be beneficial to environmental protection; Guarantee health safety, increased the business economic benefit.
Description of drawings
Fig. 1 is the structural representation of the utility model bromine packing device for recovering tail gas.
The specific embodiment
As shown in Figure 1; The utility model bromine packing device for recovering tail gas comprises exhaust collection cover 1, air blast 2, mist eliminator 3, stripping tower 4, absorption tower 5, and exhaust collection cover 1 top links to each other with the air inlet of air blast 2 through pipeline; The bottom on absorption tower 5 links to each other with the air inlet of air blast 2 through pipeline; Owing to the suction of air blast 2, the tower internal pressure is micro-vacuum state in the absorption tower 5, and pressure is 270mmHg.The outlet of air blast 2 communicates through the bottom of pipeline with mist eliminator 3, the mist eliminator 3 inner fillers 32 of filling, and filler occupies 2/3 of mist eliminator 3 volumes, and filler is Φ 50 cascade rings.Mist eliminator 3 tops are provided with absorption liquid spray pipeline 33; The bottom of mist eliminator 3 is provided with absorption liquid outlet 31, and absorption liquid outlet 31 communicates through the bottom of pipeline with absorption tower 5, and the gas vent 34 on mist eliminator 3 tops communicates through the bottom of pipeline with stripping tower 4; Bittern import 41 is offered on the top of stripping tower 4; Bittern import 41 connects bittern feed tube 42, and the gas vent 43 at stripping tower 4 tops communicates through the top of transfer pipeline 44 with absorption tower 5, connects SO on the transfer pipeline 44
2Air inlet pipe 45 and water inlet pipe 46, stripping tower 5 bottoms are provided with bittern liquid outlet 47, and 5 bottoms, absorption tower are provided with absorption liquid liquid outlet 51, and absorption liquid liquid outlet 51 communicates with absorption liquid storage tank 52 through pipeline.
