Background
In the modern industrial production process, various harmful gases are generated in reaction kettles of various chemical production, in the aspect of treating the harmful gases, a commonly adopted method is to filter the harmful gases, in the filtering process, the most used filtering means is to use a spray tower for filtering, the spray tower has the advantages of simple structure, low manufacturing cost, small gas pressure drop and the like, and is widely used in the process of filtering the harmful gases in industry, however, in the filtering process of the harmful gases by the spray tower, a part of gases are not fully absorbed, the part of gases which are not fully absorbed are often directly discharged into the atmosphere, and the atmosphere is polluted to a certain extent, so that a factory starts to use a water jet vacuum pump unit to carry out secondary filtering on the harmful gases, however, the water tank of the existing water jet vacuum pump unit has small volume, this is unfavorable for keeping the temperature stable, still needs a large amount of cooling water to cool down in order to keep stable temperature, and this can produce a large amount of circulation sewage, and the sewage treatment cost of enterprise rises, and the inside buffer space of water tank is little for circulation liquid leaks easily, and moreover, if need absorptive gas too much, still need add and establish water injection vacuum pump unit, and this makes the takeover become more complicated and easily cause the pollution.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's is not enough, provides a hydrogen chloride tail gas administers device, and its water tank inside buffer space is big, and the circulating liquid is difficult for leaking, takes over moreover fewly, and the condition emergence of running the overflow has been avoided to the at utmost.
The problem is solved through following technical scheme:
a hydrogen chloride tail gas treatment device comprises a water tank, a gas outlet part, a gas inlet part, a circulating part and a sewage outlet; the air outlet part is arranged at the upper end of the water tank; the circulating part is connected with the water tank; the air inlet part is connected with the circulating part; the sewage draining outlet is arranged at the lower part of the water tank; the circulating part comprises a water injection vacuum valve, a first connecting pipe, a second connecting pipe, a third connecting pipe and a centrifugal pump; one end of the first connecting pipe is connected to the lower end of the water tank, and the other end of the first connecting pipe is connected with a water inlet of the centrifugal pump; one end of the second connecting pipe is connected with a water outlet of the centrifugal pump, and the other end of the second connecting pipe is connected with a water inlet of the water injection vacuum valve; one end of the third connecting pipe is connected with a mixing outlet of the water injection vacuum valve, and the other end of the third connecting pipe is connected to the upper end of the water tank; the air inlet part comprises an air transmission pipeline and an air guide pipe; one end of the air duct is connected with the air transmission pipeline, and the other end of the air duct is connected with the air inlet of the water injection vacuum valve; the circulating parts are distributed on the water tank uniformly; the number of the air ducts and the number of the circulating parts are the same, and each circulating part is connected with the air conveying pipeline through the corresponding air duct.
In the hydrogen chloride tail gas treatment device, the gas outlet part comprises a gas outlet pipe and a discharge pipeline; one end of the air outlet pipe is connected with the water tank, and the other end of the air outlet pipe is connected with the discharge pipeline.
The utility model discloses a large-scale water tank has promoted the capacity of the absorptive gas that can, it is not only buffer space big, but also avoided the problem that little water tank possessed in the past is small and the intensification is fast, in little water tank in the past, because small, buffer space is not enough, so circulation liquid leaks easily, cause job site's sewage to reveal seriously, and little water tank is because the water yield is few, so it is fast to heat up, often need a large amount of cooling water to cool down, this will produce a large amount of circulation sewage, the sewage treatment cost of enterprise rises, after adopting big water tank, above-mentioned problem has all obtained the solution.
In addition, the combination of a plurality of groups of vacuum pump units greatly enhances the capability of circularly absorbing the discharged gas, accelerates the filtering speed,
