Description
Technical field
The present invention relates to acid mist absorption unit in hydrochloric acid production and the storage and transport process, specifically is that a kind of environment-friendly and energy-efficient hydrochloric acid mist is collected the absorption sulphuric acid plant.
Background technology
High purity hydrochloric acid has extremely strong volatility, and in high purity hydrochloric acid entrucking process, a large amount of hydrogen chloride gas volatilizations back combines with airborne water vapour and produces the hydrochloric acid small droplets, is discharged in the air.On the one hand cause hydrogen chloride gas to efflux loss, severe contamination entrucking operating environment on the other hand, it is healthy to influence the entrucking personnel.At present, the acid mist that produces during domestic still unmatchful high purity hydrochloric acid entrucking is collected the device that absorbs relieving haperacidity.
Summary of the invention
Acid mist pollution that the present invention produces when being intended to solve the high purity hydrochloric acid entrucking and hydrogen chloride gas volatilization waste problem, and provide a kind of acid mist that produces in the high purity hydrochloric acid entrucking process of can collecting, and reclaim and make hydrochloric acid, absorb sulphuric acid plant with the environment-friendly and energy-efficient hydrochloric acid mist collection that improves hydrochloric acid entrucking Working environment, the waste of reduction volatilization hydrogenchloride.
The technical scheme that the present invention solves described problem employing is: a kind of environment-friendly and energy-efficient hydrochloric acid mist is collected and is absorbed sulphuric acid plant, comprise acid mist collection seal closure, acid fog absorption tower, this acid mist is collected seal closure and is installed in high purity hydrochloric acid tank car wagon spout, its gas collection mouth is connected with the acid mist import of acid fog absorption tower by the acid mist intake line, the diluted acid liquid outlet of described acid fog absorption tower bottom is connected with the diluted acid shower that is provided with in hydrochloric acid tank and the acid fog absorption tower respectively by the liquid phase connecting pipeline, and the liquid phase connecting pipeline of this diluted acid fluid oral area is provided with the salt acid circulating pump; The tail gas outlet at described acid fog absorption tower top is connected with positive water seal by the gas phase connecting pipeline, and this section gas phase connecting pipeline is provided with blower fan; The pure water water-supply line of its interior hydrochloric acid of dilution is equipped with in described acid fog absorption tower bottom.
Compared with prior art, the invention has the beneficial effects as follows: by the organic assembling of acid fog absorption tower with positive water seal, the diluted acid shower is evenly distributed to blossom type packing layer in the tower with diluted acid, basically all absorbed the acid mist that in high purity hydrochloric acid entrucking process, produces, acid fog absorption tower tail gas absorbs once more by positive water seal, guarantee the zero release of hydrogen chloride gas, the acid mist pollution problem that has produced when promptly having solved the high purity hydrochloric acid entrucking, improved high purity hydrochloric acid entrucking operating environment, reclaim the evaporable hydrogen chloride gas again, realized the purpose of environmental protection and energy saving.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
Fig. 2 is the acid fog absorption tower structural representation of the embodiment of the invention.
Among the figure: acid fog absorption tower 1, pure water water-supply line 2, salt acid circulating pump 3, liquid phase connecting pipeline 4, gas phase connecting pipeline 5, blower fan 6, positive water seal 7, hydrochloric acid tank 8, acid mist intake line 9, acid mist is collected seal closure 10, diluted acid liquid outlet 11, following packing layer back up pad 12, following blossom type packing layer 13, diluted acid shower 14, last packing layer back up pad 15, last blossom type packing layer 16, tail gas outlet 17, acid mist import 18, liquidometer 19.
Embodiment
Below in conjunction with embodiment in detail the present invention is described in detail.
Referring to Fig. 2, as a kind of preferred structure, 1 tower body of acid fog absorption tower described in the present embodiment is a tubular structure, blossom type packing layer 16, last packing layer back up pad 15, diluted acid shower 14, following blossom type packing layer 13, following packing layer back up pad 12 are housed respectively in it from top to bottom, this time packing layer back up pad 12 belows are the diluted acid pond, this tower body outside, place is respectively arranged with acid mist import 18 and diluted acid liquid outlet 11, and diluted acid liquidometer 19 in the tower is installed.
Referring to as Fig. 1, the present invention is made of acid fog absorption tower 1, salt acid circulating pump 3, blower fan 6, positive water seal 7, hydrochloric acid tank 8, and the gas collection mouth that the acid mist import 18 of acid fog absorption tower 1 is collected seal closure 10 by acid mist intake line 9 and the acid mist that is installed in high purity hydrochloric acid tank car entrucking oral area is connected; The diluted acid liquid outlet 11 of acid fog absorption tower 1 bottom is connected with diluted acid shower 14 with hydrochloric acid tank 8 respectively by liquid phase connecting pipeline 4, on the liquid phase connecting pipeline 4 that the diluted acid liquid outlet is 11 ones salt acid circulating pump 3 is housed, the gas phase connecting pipeline 5 between salt acid circulating pump 3 and the diluted acid liquid outlet 11 also is connected with the pure water water-supply line 2 of hydrochloric acid in the dilution acid fog absorption tower 1; The tail gas outlet 17 at acid fog absorption tower 1 top is connected with positive water seal 7 by gas phase connecting pipeline 5, on this section gas phase connecting pipeline 5 blower fan 6 is housed.
Working process of the present invention is summarized as follows: salt acid circulating pump 3 is delivered to diluted acid shower 14 with acid fog absorption tower 1 bottom diluted acid by liquid phase connecting pipeline 4, evenly spray blossom type packing layer 13 extremely down, the blossom type filler is with the diluted acid uniform distribution, contacting of maximum area, fully absorbing hydrogen chloride gas with hydrochloric acid mist; Because the hydrochloric acid mist airshed is bigger, the part diluted acid with rise to blossom type packing layer 16 by the gas of blossom type packing layer 13 down and contact once more, one side can make the abundant absorbing hydrogen chloride gas of diluted acid, it is 17 excessive to prevent that on the other hand diluted acid from exporting from tail gas.Make regular check on dilute acid concentration, when dilute acid concentration reaches standard, by salt acid circulating pump 3 the hydrochloric acid storage is delivered in the acid in the acid fog absorption tower 1 and irritated 8, and replenish pure water, by the effective liquid level of liquidometer 19 control diluted acids by 2 pairs of diluted acids of pure water water-supply line.When carrying out high purity hydrochloric acid entrucking operation, acid mist to be collected seal closure 10 cover on hydrochloric acid tank car wagon spout, blower fan 6 makes and forms negative pressure in the acid fog absorption tower 1, and the acid mist that hydrochloric acid is volatilized is drawn in the acid fog absorption tower 1, and hydrogen chloride gas is all absorbed substantially; The tail gas that acid fog absorption tower 1 is discharged passes through positive water seal 7 again, all reclaims hydrogen chloride gas.
This device has effectively improved high purity hydrochloric acid entrucking operating environment, guarantees the zero release of hydrochloric acid mist, has realized the purpose of environmental protection and energy saving.
