Abstract
The utility model relates to a hot acid gas treatment system. The hot acid gas treatment system comprises a gas collection device for collecting disperse acid gas through negative pressure, a chemical scrubbing tower for performing chemical pretreatment on the acid gas fed by the gas collection device, and a biological filter bed for performing biological absorption and decomposition on the acid gas fed by the chemical scrubbing tower, wherein gas filtered by the biological filter bed is clean gas. According to the chemical scrubbing tower and the biological filter bed, the acid gas is sequentially absorbed and decomposed. Compared with simple means of neutralizing the acid gas by using alkaline substances, the system has the advantages that the acid gas can be effectively purified, and emission of harmful gases is reduced. Meanwhile, the disperse acid gas can be collected in a unified mode by the gas collection device by using negative pressure, the collection efficiency is improved, the residual acid gas is reduced, and the acid gas purification rate is further improved.
Description
Technical field
The utility model relates to chemical industry pollution treatment field, relates in particular to a kind of hot acid gas processing system.
Background technology
Along with industry and the developing rapidly of transportation, pernicious gas and flue dust air has been caused to severe contamination. controlling each control atmosphere pollution, will be that the mankind will face important problem.Foul smell is the volatile gas of a class, its molecule spreads in air, serious harm mankind's environment of depending on for existence, be inhaled into the olfactory organ of human body, cause offending sensation, then the former respiratory system of people, the circulatory system, digestive system, the state of mind are brought to harm in various degree.
In last one surface treatment procedure that the fine level of electronic glass cloth is produced, can use contain≤2% glacial acetic acid treatment fluid, extremely strong because of glacial acetic acid volatility, in high-temperature heating process, become to have tart flavour gaseous volatilization out.For surrounding environment not being impacted, after must doing effectively to purify to hot acid gas, could discharge.Generally all to use alkaline matter that it is neutralized and is just disposed in atmosphere afterwards to the processing of acid gas, lower to the purifying rate of acid gas like this, easily to environment.
Utility model content
The purpose of this utility model is to provide a kind of hot acid gas processing system, to improve the effective purifying rate to hot acid gas, reduces the pollution to environment.
For achieving the above object, the utility model is by the following technical solutions:
A kind of hot acid gas processing system, comprise by negative pressure and collect and disperse the biofilter that the gas collecting apparatus of acid gas, acid gas that gas collecting apparatus is sent here carry out the chemical scrubber of Chemical Pretreatment, acid gas that chemical scrubber is sent here carries out bio-absorbable decomposition, the gas after biofilter filters is clean gas.
Hot acid gas processing system also comprises the spray equipment that is used to acid gas cooling, and the acid gas that gas collecting apparatus is collected first just enters in gas collecting apparatus through the cooling of spray equipment.
Between gas collecting apparatus and chemical scrubber and between chemical scrubber and biofilter, be equipped with the centrifugal blower transmitting for accelerating acid gas.
In chemical scrubber, be provided with organic filler layer and the inorganic filler layer that can make to acid gas chemical absorbing.
In biofilter, be provided with biomembrane, biomembrane is provided with and can absorbs the microorganism layer decomposing to acid gas.
In biofilter, be also provided with for the shower nozzle to acid gas water spray and for dissolving the filling moisture film through the acid gas of shower nozzle spray.
The utility model beneficial effect is compared with prior art:
The utility model is provided with chemical scrubber and biofilter absorbs acid gas successively and decomposes, compare in simple use alkaline matter and the means of acid gas, system of the present utility model can more effectively purify acid gas, has reduced the discharge of pernicious gas; Gas collecting apparatus can be unified the acid gas of dispersion to collect by negative pressure simultaneously, has improved the efficiency of collecting and has also reduced residual acid gas simultaneously, has further improved the purifying rate of acid gas.

The specific embodiment
In order to more fully understand technology contents of the present utility model, below in conjunction with specific embodiment, the technical solution of the utility model is described further and is illustrated.
The structured flowchart of the utility model embodiment as shown in Figure 1 to Figure 3.
The hot acid gas processing system of the present embodiment comprises gas collecting apparatus 10, chemical scrubber 20, biofilter 30, spray equipment 40 and centrifugal blower 50.Between these devices, be communicated with by pipeline 60 above.
The acid gas that chemical scrubber 20 is sent gas collecting apparatus 10 here carries out Chemical Pretreatment (prime carrying out washing treatment).According to the special nature of institute's heat extraction acid gas, the internal structure of chemical scrubber 20 adopts existing structure, but organic filler layer and the inorganic filler layer that can make to acid gas chemical absorbing need be set in chemical scrubber 20 pointedly, and adopt the mode of Gas-Liquid Contacting to make chemical absorbing to acid gas, also can do to it pretreatment of dedusting and humidification simultaneously.
Biofilter 30 carries out bio-absorbable decomposition by chemical scrubber 20 from the acid gas of sending here, and the gas after biofilter 30 filters is clean gas, can discharge the external world.In biofilter 30, be provided with for the nozzle 31 to acid gas water spray and for dissolving the filling moisture film 32 of the acid gas spraying through nozzle 31.In biofilter 30, be also provided with biomembrane 33, biomembrane 33 is provided with and can absorbs the microorganism layer decomposing to acid gas.Acid gas enters biofilter 30 and contacts and dissolve with filling moisture film 32 under the effect of nozzle 31 spraying liquid water, and acid gas enters biomembrane 33 and absorbs to divide to take off at microorganism layer and is eliminated simultaneously, can give off innocuous gas.
More than statement only further illustrates technology contents of the present utility model with embodiment; so that reader is easier to understand; but do not represent that embodiment of the present utility model only limits to this, any technology of doing according to the utility model is extended or recreation, is all subject to protection of the present utility model.
