Description

Hydrochloric acid tank exhaust, anti-negative pressure and entrucking acid gas absorb control system
Technical field
The utility model belongs to the control system of acid storage tank volatile, soluble in water in solution cargo handling process, especially It is related to a kind of hydrochloric acid tank exhaust, anti-negative pressure and entrucking acid gas and absorbs control system.
Background technology
Volatile acid solution will exclude gas unnecessary in tank in time because of the rising of pot liquid liquid level when injecting and storing, To prevent from damaging caused by pressure inside the tank is too high to storage tank.Similarly to be mended in time when storing up pot liquid output and causing liquid level to decline Enter certain gas flow, prevent because negative pressure is damaged caused by tank body.How pressure inside the tank balances, and escaping gas is discharging When how to handle, there is a different methods in each enterprise, and in general is all that safety valve, atmospheric valve and negative pressure valve etc. are installed on tank body, Loading-unloading vehicle is by the acid gas absorption system being made up of tower, pump and blower fan to match.The shortcomings that above-mentioned is that assimilation effect is undesirable, dress It is big to put floor space, pressure inside the tank is unbalanced, certain hidden danger all be present in terms of secure context or environmental protection.
The content of the invention
It is an object of the invention to overcome above-mentioned technical deficiency, there is provided a kind of whole system automatic pressure-balancing, no waste liquid Discharge, hydrochloric acid tank exhaust, anti-negative pressure and the entrucking acid gas of safety and environmental protection absorb control system.
Technical scheme is used by the utility model solves technical problem:A kind of hydrochloric acid tank exhaust, anti-negative pressure and dress Car acid gas absorbs control system, including enters sour pump, storage tank, entrucking tourie and pay sour pump, it is characterised in that storage tank is inhaled with entrucking Water aspirator pipeline connection in closed cans, negative pressure valve is equipped with by valve on pipeline;Being equipped with by valve for storage tank lower end is paid Sour pump connects with wagon spout, and valve is housed on the pipeline paid between sour pump and wagon spout;Wagon spout is connected with injector with pipeline It is logical;Injector left end pipeline is connected with storage tank and entrucking absorption pump, and valve is respectively arranged with pipeline;Entrucking absorption pump pipeline Connected with entrucking tourie, valve is housed on pipeline;Injector has section pipeline to be connected with entrucking tourie.
The beneficial effects of the utility model are:The utility model whole system automatic pressure-balancing, acid gas absorption efficiency is good, Without discharging of waste liquid, safety and environmental protection;Equipment investment is few, and floor space is small, without manual adjustment and operation.
Brief description of the drawings
Below in conjunction with accompanying drawing, illustrated with embodiment.
Fig. 1 is the system diagram that hydrochloric acid tank exhaust, anti-negative pressure and entrucking acid gas absorb control system.
In figure:1- enters sour pump;2- storage tanks;3- negative pressure valves;4- blow-down pipes;5- entrucking touries;6- filling pipes;7- entruckings are inhaled Receive pump;8- injectors;9- wagon spouts;10- pays sour pump;11- water aspirators;12- valves;13- pipelines.
Embodiment
Embodiment, referring to the drawings, a kind of hydrochloric acid tank exhaust, anti-negative pressure and entrucking acid gas absorb control system, including enter Sour pump 1, storage tank 2, entrucking tourie 5 and pair sour pump 10, it is characterised in that storage tank 2 is used with the water aspirator 11 in entrucking tourie 5 Pipeline 13 connects, and negative pressure valve 3 is housed by valve 12 on pipeline 13;A sour pump 10 is paid in being equipped with by valve 12 for the lower end of storage tank 2 Connected with wagon spout 9, valve 12 is housed on the pipeline paid between sour pump 10 and wagon spout 9;Wagon spout 9 and the pipe of injector 8 Road connects;The left end pipeline 13 of injector 8 is connected with storage tank 2 and entrucking absorption pump 7, and valve 12 is respectively arranged with pipeline 13;Dress Car absorption pump 7 is connected with pipeline with entrucking tourie 5, and valve 12 is housed on pipeline;Injector 8 has section pipeline and entrucking Tourie 5 connects.
Enter sour pump 1 to be connected with storage tank 2 with pipeline 13, valve 12 is filled on pipeline 13, enters entering for sour pump 1 and is also equipped with acid tube Valve 12;Blow-down pipe 4 and filling pipe 6 are housed on entrucking tourie 5, valve 12 is housed on filling pipe 6.
The operation principle and process of the system be:First, when entering sour pump 1 to 2 acid filling of storage tank, pressure is with liquid in storage tank 2 Position rises and raised, and acid gas is discharged by blow-down pipe 4, and negative pressure valve 3 is automatic under stress to close, and gas enters in entrucking tourie 5 Absorber 11, air is discharged into by blow-down pipe 4 after being fully absorbed by liquid in tank.2nd, when a pair sour pump 10 outwards takes out acid from storage tank 2 To during 9 entrucking of wagon spout, pressure reduces as liquid level declines in storage tank 2, when the pressure of storage tank 2 is less than outside atmospheric pressure, Negative pressure valve 3 automatically opens up, and fills into air automatically into storage tank 2, ensures gas balance inside and outside storage tank 2, prevents the negative pressure pair to be formed Storage tank 2 causes to damage.3rd, during sour entrucking, entrucking absorption pump 7 is opened, and liquid absorbs pumped warp by entrucking in entrucking tourie 5 Enter again in storage tank 2 after injector 8 and circulated.Negative pressure caused by injector 8 is used for drawing because producing during entrucking through wagon spout 9 Acid gas, prevent that acid gas is excessive caused by entrucking.The acid gas of absorption is discharged into greatly after being fully absorbed by liquid in entrucking tourie 5 Gas.4th, when the strength of fluid in entrucking tourie 5 rises, and assimilation effect reduces, the liquid in entrucking tourie 5 is through being mounted in Absorption pump 7 and pipeline 13 are poured into storage tank 2, mounted in entrucking tourie 5 by filling pipe 6;Valve 12 is opened from new feeding-in liquid.
