Description

Technical Field

[0001] This utility model relates to the field of odorous waste gas treatment technology, specifically to an odorous waste gas treatment device. Background Technology

[0002] Wastewater treatment plants and landfills are filled with foul-smelling gases. These gases mainly originate from wastewater treatment and waste decomposition processes, and have a significant impact on human health and the environment.

[0003] Chinese patent CN207153437U discloses a garbage odor treatment device, comprising a housing, an air inlet, and a filter. The air inlet is located at the bottom of the adsorption box. An electric motor is installed inside the adsorption box and fixed to the inner wall of the box via a motor mounting bracket. The motor's output shaft is connected to a rotating shaft via a coupling. At least two activated carbon plates are fixed to the rotating shaft. One end of an air outlet pipe is connected to the top of the adsorption box, and an exhaust fan is installed on the outlet pipe. The other end of the outlet pipe is inserted into the bottom of a deodorizing agent tank containing deodorizing agent. This device uses the electric motor to drive the activated carbon plates to rotate, increasing the airflow within the adsorption box and ensuring sufficient contact between the odor and the activated carbon plates, thus improving the adsorption efficiency. Through adsorption by the activated carbon plates and reaction between the deodorizing agent and the odor, this device can completely remove odors generated by garbage.

[0004] However, it still has the following drawbacks: the device introduces air into the deodorizing agent for air purification, but the gas entering the deodorizing agent floats upward in the form of bubbles, resulting in very limited contact area between the air and the deodorizing agent and poor deodorization effect. Therefore, we propose an odorous waste gas treatment device to solve this problem. Utility Model Content
