The suction hood 13 and the fan 6 are used for drawing exhaust gas into the exhaust gas treatment device. When the fan 6 is in operation, air tends to flow from the outside to the inside of the housing 11, so that the housing 11 does not need to be sealed, and a vent hole with an activated carbon net can be arranged at the bottom. The spray device 21 cools the exhaust gas and absorbs some components of the exhaust gas, and water or a suitable chemical agent may be used. Water or chemical reagents flow back to the sewage treatment equipment through the water outlet 24 for treatment, and the environment is not polluted. A valve is arranged at the water outlet 24, and the opening degree of the valve is determined according to the liquid flow of the spraying device 21, so that a certain amount of liquid exists at the bottom of the washing chamber 2, and the waste gas is prevented from flowing out of the water outlet 24.

Specifically, in the sewage treatment process, a plurality of equipment can produce waste gas, sets up a plurality of waste gas collecting chamber 1 collects waste gas, then centralized processing. The check valve prevents the exhaust gas from flowing backward and the exhaust gas of a certain equipment flows into the exhaust gas collecting chamber 1 where other sewage treatment equipment is located.
The shell 11 is an aluminum alloy shell, and the upper half part of the shell 11 is provided with a sealing strip 14. The aluminum alloy is corrosion resistant, low in cost and not easy to damage. The exhaust gas is mainly concentrated in the upper part of the exhaust gas collecting chamber 1, and the sealing strips 14 are added to prevent the exhaust gas from flowing into the environment.
The top and the bottom of the washing chamber 2 are both in a hemispherical shape, so that water and gas can be conveniently concentrated, and the water at the bottom is concentrated above the water outlet 24, so that the sealing property can be improved.
The comprehensive waste gas treatment system further comprises a control system, a gas flowmeter is arranged at the position of the inlet 23 of the washing chamber, and the control system is respectively connected with the gas flowmeter, the spraying device 21, the water outlet 24, the inlet 51 of the safety chamber and valves at the position of the outlet 52 of the safety chamber. Specifically, the gas flow meter is used for monitoring the entering amount of the waste gas, and controlling the spraying amount of the spraying device 21 according to the adding amount of the waste gas, so that the waste gas is fully contacted with water or a chemical reagent. The liquid at the bottom of the washing chamber 2 should be able to flood the water outlet 24 and should not be higher than the inlet 23 of the washing chamber, so the valve at the water outlet 24 should be changed according to the liquid spraying amount of the spraying device 21. If too much exhaust gas is to be treated, part of the exhaust gas is temporarily stored in the safety chamber 5. When the amount of the waste gas to be treated is reduced, the waste gas stored in the safety chamber 5 is introduced into the chemical adsorption chamber 3 for treatment.
The pipeline is provided with an anti-corrosion coating to prevent the pipeline from being damaged.
A pressure alarm is arranged in the safety chamber 5, so that the waste gas is prevented from being stored too much and causing danger. It should be further noted that other components are adopted to achieve the above effects, and all the components are considered to fall within the inventive concept of the present invention and are considered to fall within the protective scope of the present invention.
The sewage treatment apparatus includes a biological treatment tank and a chemical treatment tank, for example: a regulating tank, a flotation tank, an acidification tank, an oxidation tank and the like. The chemical reaction and biological treatment process can generate waste gas, and the waste gas comprehensive treatment system can collect and treat the waste gas of the devices.
Example two
Referring to fig. 5, three waste gas collecting chambers 1 are provided, the number of inlets 23 of the washing chamber is one, and a check valve is disposed on a pipeline connecting each waste gas collecting chamber 1 and the inlet 23 of the washing chamber.
The working principle is as follows: waste gas that sewage treatment device work produced concentrates on in the room 1 is collected to waste gas under the effect of fan 6, the warp inhale the cover 13 the surge chamber import 23 gets into in the surge chamber 2, the liquid that spray set 21 sprayed is cooled down and is absorbed waste gas. The liquid flows back to the sewage treatment equipment for treatment, the gas flows into the chemical adsorption chamber 3 and the biological treatment chamber 4, and the gas is discharged into the environment after desulfurization, alkali adsorption, acid adsorption, photocatalysis, microbial treatment and activated carbon filtration. In the event of excess exhaust gases, these are temporarily stored in the safety chamber 5.
