Description

Technical Field

[0001] The utility model belongs to the technical field of waste gas treatment, and relates to an exhaust gas recovery structure for sewage treatment. Background Technique

[0002] Sewage treatment refers to the purification process of treating sewage to meet the requirements of a certain water body or to be reused. A large amount of sewage is generated in people's daily life and various industrial productions in cities. If these sewage are directly discharged without treatment, it will cause serious pollution to the environment. Therefore, it is necessary to recover and treat the sewage exhaust gas and then discharge it to avoid polluting the air.

[0003] The existing sewage exhaust gas contains water, various volatile organic compounds, sulfides, nitrides, oxygen-containing organic compounds, halogens and their derivatives, heavy metals, etc. When treating the sewage exhaust gas, the adsorbent deodorization method is usually adopted. A large amount of activated carbon is consumed when treating the exhaust gas, and the removal effect is not thorough, resulting in great waste. Therefore, we propose an exhaust gas recovery structure for sewage treatment. Content of the Utility Model

[0004] The purpose of the utility model is to address the above problems existing in the prior art and propose an exhaust gas recovery structure for sewage treatment. The technical problem to be solved by this device is: how to improve the treatment effect of sewage exhaust gas.

The water outlet end of the water pump is connected with a liquid delivery pipe. The end of the liquid delivery pipe is connected with a communicating pipe. A spraying pipe is connected below the communicating pipe. A plurality of spraying heads are arranged below the spraying pipe. An installation arc plate is arranged on the side of the tower body. A filter screen is arranged on the installation arc plate. An air supply assembly is arranged above the tower body. The end of the air supply assembly is connected with a deodorization assembly. An adsorption assembly is arranged above the deodorization assembly.

[0007] The air supply assembly includes a delivery pipe which is in an S shape. One end of the delivery pipe is connected above the tower body. An air pump is arranged on the delivery pipe. A one-way valve is arranged on the delivery pipe.

[0008] With the above structure, the air pump pumps the exhaust gas inside the tower body into the inside of the delivery pipe, thereby delivering the exhaust gas into the inside of the deodorization assembly. The one-way valve can prevent the exhaust gas from flowing back.

[0009] The deodorizing component includes a reaction tank, an air-permeable box is arranged inside the reaction tank, the other end of the conveying pipe is connected to the air-permeable box, and a microbial layer is arranged inside the reaction tank.

[0010] With the above structure, the air pump pumps the waste gas inside the tower body into the air-permeable box, the air-permeable box conveys the waste gas to the bottom of the microbial layer, and the microorganisms adsorb, absorb and degrade the malodorous substances (hydrogen sulfide, ammonia, volatile acids, mercaptans, etc.) in the waste gas, and decompose the malodorous substances (hydrogen sulfide, ammonia, volatile acids, mercaptans, etc.) into odorless and harmless inorganic substances.

[0011] The adsorption component includes an adsorption box, several support columns are fixed below the adsorption box, several support columns are all fixed above the reaction tank, several sliding grooves are opened on the side of the adsorption box, an installation frame is slidably arranged inside the sliding grooves, an activated carbon layer is arranged inside the installation frame, and several support rods are fixed on the adsorption box, and several support rods are all located below the installation frame at the corresponding positions.

[0012] With the above structure, the activated carbon layer adsorbs the volatile organic compounds in the waste gas, so as to recycle the organic compounds. After the activated carbon layer is used for a period of time, the installation frame is pulled out from the inside of the sliding groove, and a new activated carbon layer is replaced.

[0013] A suction fan is arranged below the adsorption box, the suction fan connects the reaction tank and the adsorption box, a cover plate is arranged above the adsorption box, and an exhaust pipe is arranged above the cover plate.

[0014] With the above structure, the suction fan pumps the waste gas inside the reaction tank into the adsorption box, and the exhaust pipe can discharge the waste gas inside the adsorption box.

[0015] Compared with the prior art, the waste gas recovery structure for sewage treatment has the following advantages:

[0016] Through the cooperation of the spraying component and the adsorption component, the spraying pipe conveys the spraying water to several spray heads, and several spray heads spray and treat the waste gas, so as to remove (or carry out a neutralization reaction) the solid particles and part of the acidic (alkaline) gas in the waste gas. At the same time, the filter screen can centrally collect these solid particles for convenient recycling. The air pump pumps the waste gas after spraying treatment into the conveying pipe, so as to convey the waste gas into the air-permeable box. The suction fan pumps the waste gas inside the reaction tank into the adsorption box, and the activated carbon layer adsorbs the volatile organic compounds in the waste gas, so as to recycle the organic compounds. Through multiple treatments, not only the harmful substances in the waste gas are removed, but also the consumption of activated carbon is reduced, and the treatment effect of sewage waste gas is improved.
