Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment shall fall within the protection scope of the present invention.
It please refers to Fig.1 shown in -7, specific embodiment provided by the invention is as follows：
One kind of the present embodiment the technical scheme is that, a kind of water curtain type gas handling system is provided, including having
Air inlet 10 and the gas chamber of gas outlet 11 1,12 inner wall of plenum roof are equipped with spray module 2, can be used to when connecting water source
Water spray forms cascade；The gas chamber bottom 14 includes plash 3, can be used to the water that accumulation spray module sprays；The system is also
The component 4 that draws water including connection plash and spray module can be used to provide the water source of spray module.Water described in the present embodiment
Curtain gas handling system is useless available for being discharged during the processing fermented technique productions organic fertilizer of farm's feces of livestock and poultry
Gas.Feces of livestock and poultry is higher because of its script moisture content, it is difficult to and it handles, if without fermentation process, raw excrement is directly applied to soil,
The root of crops can be injured, interferes the growth of plant.Under aerobic conditions, due to the effect of aerobic bacterium, animal manure will be removed
In the harmful substance that is generated in decomposable process of organic matter, while evaporate the moisture in animal manure, be allowed to become easy-to-handle
Organic fertilizer.And during livestock manure fermented, a large amount of foul gas can be generated.These foul smell compositions are mainly ammonia, sulfur-bearing
The chemical substances such as compound, amine and some lower aliphatic acids.It is a large amount of by generating in the continuous progression of aerobic fermentation
NH3, NH3It is most important composition in foul smell, there is strong sharp aroma, health and air to people cause seriously
Pollution problem.It since ammonia is to the sorptive very high of water, and is dissolved in after water in alkalinity, therefore, in the present embodiment proposes to utilize
Cascade removes the exhaust gas discharged during the cleaning fermented technique productions organic fertilizer of farm's feces of livestock and poultry.Specifically, by excrement
The exhaust gas generated in the continuous fermentation process of fermentation vat is introduced into through air inlet in gas chamber, and the spray module can be used to spray containing acidity
The liquid of solution can spray liquid downward from plenum roof and form cascade, acid solution and the NH in gas chamber3Neutralization reaction occurs
NH is removed so as to reach3The purpose of (while also deodorization), exhaust gas after treatment are discharged from gas outlet.Gas chamber bottom setting product
Pond can accumulate the liquid that spray module constantly sprays, and by the setting for the component that draws water, can reuse in plash
Water source of the liquid as spray module, and be delivered to spray module and spray to form cascade, achieve the purpose that recycle water, save
Water resource.In addition, the gas temperature given off just through fermentation process is very high, by the gas that air inlet of air chamber is collected through water spray
During the cascade cleaning that component is formed, the temperature of gas can also be reduced.
Preferred embodiment scheme, the system also includes acid solutions to add component, to be added into the plash
Acid solution.In the continuous progression of aerobic fermentation, a large amount of NH will be generated3, in the continuous cleaning process of exhaust gas, spray
The acid solution and NH that water assembly sprays3After reacting, the pH value of solution constantly increases, when in the component extraction plash that draws water
Liquid make spray module cleaning NH3Water source when, pH value raising after solution will be not enough to cleaning NH3, therefore, the present embodiment
The gas handling system further includes acid solution addition component, is not enough to clean after solution pH value raising in plash
NH3(cleaning efficiency is relatively low) can add acid solution into plash.
Preferred embodiment scheme, the acid solution addition component include addition trigger module and addition control module, institute
Addition trigger module is stated for output signal triggering acid solution addition component addition acid solution；The addition control module root
The control signal of acid solution whether is added according to the signal generation of addition trigger module output.It is reasonable to acid solution addition component
Design addition trigger module and the function module for adding control module can increase the stability of system.Specifically, the addition is touched
It can be pH value detection module to send out module, can detect the pH value of solution in plash in real time, and being increased to threshold value M to pH value (can be with
Threshold value is set according to actual conditions, such as NH of the fermentation vat within certain a period of time in discharge exhaust gas3Content) when, output signal is touched
The control signal of hair addition control module generation addition acid solution.Using the above scheme, the water in plash is recycled
It is formed on the basis of cascade, further realizes the automation of acid solution addition, reduce artificial participate in.
Preferred embodiment scheme, the spray module 2 include main jet water pipe 20 and branch sparge pipe 21, and the main jet water pipe connects
The component that draws water is connect, the main jet water pipe can be used to be introduced into the water in plash and be delivered to branch sparge pipe；The branch water spray
Pipe connects the main jet water pipe, and the branch sparge pipe 21 is equipped with hole for water spraying 210, and the opening of hole for water spraying is towards gas chamber bottom.This
Main jet water pipe can connect water source in embodiment, and water is delivered to branch sparge pipe, and branch sparge pipe is equipped with hole for water spraying, when access water
During source, water sprays to form cascade along hole for water spraying.
Preferred embodiment scheme, the branch sparge pipe 21 set multiple, each branch sparge pipe interval L1Distance setting, it is more
A branch sparge pipe 21 forms pectination with main jet water pipe 20 and is arranged in plenum roof 12.Due to random fortune of the gas in space
It is dynamic, enough cascades therefore, in plenum space is needed to remove cleaning exhaust gas.To ensure to be formed than more uniform water in plenum space
Curtain ensures to form cascade cleaning exhaust gas at plenum space different location, improve the cleaning efficiency of exhaust gas, setting is more in the present embodiment
A branch sparge pipe, each branch sparge pipe interval L1Distance setting, wherein L1It is chosen as 50cm, multiple sparge pipes and main jet water
