Description

Technical Field

[0001] This utility model relates to the field of landfill gas treatment devices, specifically a landfill gas treatment device for municipal solid waste landfills. Background Technology

[0002] During the long-term accumulation and decomposition of waste, municipal solid waste landfills generate a large amount of landfill gas (mainly methane, carbon dioxide, and small amounts of nitrogen, hydrogen sulfide, etc.). These gases not only have a greenhouse effect but also contain flammable substances, so measures need to be taken to treat them. The methane in the gas is used for combustion to generate electricity, and the odor in the gas needs to be pretreated to avoid being released into the air and causing pollution. Therefore, treatment devices are needed to pretreat the gas.

[0003] In existing processing devices, gas enters the tank directly during use. The gas entering the tank directly comes into contact with the filter components inside the tank. Since the gas usually passes through the part near the inlet pipe, the filtration effect is poor, which affects the filtration of the gas. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a landfill gas treatment device for municipal solid waste landfills to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a landfill gas treatment device for municipal solid waste landfills, comprising a tank, a top cover installed on the top of the tank, and an exhaust pipe fixed to the top of the top cover; an intake pipe fixed to one side of the tank, extending into the interior of the tank; multiple sets of first exhaust pipes disposed at the top of the intake pipe, the multiple sets of first exhaust pipes being distributed at the top of the intake pipe and arranged at an angle; diversion pipes fixed to both sides of the intake pipe, and multiple sets of second exhaust pipes disposed on both sides of the diversion pipes; and a gas filtration assembly disposed inside the tank.

[0006] By adopting the above technical solution, and by setting multiple sets of first exhaust pipes and multiple sets of second exhaust pipes, the problem of gas concentrating in one place is solved. The first and second exhaust pipes disperse the gas entering the intake pipe, allowing the gas to pass through the activated carbon plate in a dispersed manner, thus avoiding the problem of gas concentrating in one place and causing poor filtration effect of the activated carbon plate.

[0007] The present invention is further configured such that a fixing ring is fixed to the inner wall of the tank, and a second sealing gasket is fixed to the top of the fixing ring.

[0008] Preferably, the fixing ring can support the bottom of the limiting frame, thereby allowing the gas to pass through the gas filter assembly better and achieve the purpose of deodorization.

[0009] The present invention is further configured such that a fixing plate is fixed to the top of the tank body, and a limiting plate is fixed to the bottom of the upper cover, wherein the diameter of the limiting plate is the same as the diameter of the fixing plate, and the limiting plate and the fixing plate are fixed by bolts.

[0010] Preferably, the contact area between the tank and the top cover can be increased by setting a fixing plate and a limiting plate, and the fixing plate and the limiting plate are fixed by bolts.

[0011] The present invention is further configured such that a protruding ring is fixed at the bottom of the limiting plate, and a groove is provided at the top of the fixing plate, and a first sealing gasket is fixed on the inner wall of the groove.

[0012] Preferably, when the top cover is installed, the convex ring enters the inner wall of the groove, thereby achieving a seal at the connection between the limiting plate and the fixed plate and avoiding leakage at the connection between the top cover and the fixed plate.

[0013] The present invention is further configured such that a limiting rod is fixed at the bottom of the limiting plate, and the end of the limiting rod is arc-shaped; an insertion hole is provided at the top of the groove, and the top of the inner wall of the insertion hole is arc-shaped.

[0014] Preferably, the upper cover can be easily installed by setting a limiting rod. The limiting rod enters the inner wall of the insertion hole, thereby aligning the fixing hole and facilitating the installation of bolts.

[0015] The present invention is further configured such that fixing holes are provided inside both the limiting plate and the fixing plate.

[0016] Preferably, the fixing holes allow bolts to be easily inserted into the inner wall, thereby fixing the fixing plate and the limiting plate.

[0017] The present invention is further configured such that the gas filtration assembly includes a limiting frame and an activated carbon plate, and the limiting frame is provided with multiple sets of activated carbon plates inside.

[0018] Preferably, the gas filter assembly can adsorb odors in the gas, thus preventing pollution caused by exposure to the air.

[0019] The present invention is further configured such that the bottom of the limiting frame is arc-shaped.

[0020] Preferably, the bottom arc shape of the limiting frame facilitates its entry into the tank.

[0021] The present invention is further configured such that a handle is fixed to the top of the limiting frame, and a fixing block is fixed inside the upper cover.

[0022] Preferably, when the top cover is installed, the internal fixing block will squeeze the handle, thereby making the bottom of the limiting frame contact the second sealing gasket more tightly and preventing gas from leaking from the bottom of the limiting frame.

[0023] In summary, the present invention has the following main advantages: 1. This utility model solves the problem of gas concentrating in one place by setting up an air inlet pipe, a first exhaust pipe, a diversion pipe, and a second exhaust pipe. By setting up multiple sets of first exhaust pipes and multiple sets of second exhaust pipes, the gas entering the air inlet pipe is dispersed, so that the gas can be dispersed through the activated carbon plate, avoiding the problem of gas concentrating in one place and resulting in poor filtration effect of the activated carbon plate.

[0024] 2. This utility model features a convex ring, a limiting rod, a groove, and a first sealing gasket. The limiting rod engages with the insertion hole, facilitating the installation of the top cover. Two sets of bolts replace the flange fixing method, making the installation and removal of the top cover more convenient. At the same time, the convex ring compresses the first sealing gasket to seal the connection between the top cover and the tank body, preventing gas leakage. Attached Figure Description
