Description

Technical Field

[0001] This utility model relates to the field of waste gas purification and treatment devices, and in particular to a waste gas purification and treatment device for gas drainage wells in landfills. Background Technology

[0002] The landfill gas venting manhole exhaust gas purification and treatment device is a comprehensive system used to collect and treat gases generated in landfills, including harmful gases such as methane, carbon dioxide, and hydrogen sulfide. The device collects gases through venting manholes and further purifies them through methods such as combustion, biological treatment, or chemical absorption, ultimately ensuring that the emitted gases meet environmental protection standards, reducing environmental pollution, and improving energy recovery and utilization efficiency.

[0003] In existing waste gas purification devices, fine particulate matter in the waste gas can affect the machine and subsequent purification process. These fine particulate matter can not only clog filters and pipes, increase system resistance and reduce treatment efficiency, but also wear down equipment parts, shorten the service life of the equipment and increase maintenance costs.

[0004] Therefore, in response to the problem that fine particulate matter in the exhaust gas of the existing exhaust gas purification and treatment devices not only clogs the filters and pipes, increases the system resistance, and leads to a decrease in treatment efficiency, but also wears down equipment parts, shortens the service life of the equipment, and increases maintenance costs, a waste gas purification and treatment device for landfill gas drainage wells can be designed to spray water mist into the exhaust gas, causing the particles in the exhaust gas to settle. Utility Model Content

[0005] In order to overcome the problems in existing waste gas purification and treatment devices, such as fine particulate matter in waste gas not only clogging filters and pipes, increasing system resistance and leading to reduced treatment efficiency, but also wearing down equipment parts, shortening equipment lifespan, and increasing maintenance costs.

[0007] Preferably, the exhaust gas enters the filter cabinet through the air inlet pipe. The garbage debris and particles in the exhaust gas are filtered by the filter plate. The water in the water tank enters the water collection box through the water inlet pipe. Then, the water spray head is activated to spray the water in the water collection box into a fine water mist. The fine water mist combines with the dust and fine particles in the exhaust gas and settles at the bottom of the filter cabinet. Then, the cover is opened to remove the wastewater. Clean water can be poured into the water tank by opening the cover. The humid gas is filtered by the filter plate through the air vent pipe and enters the fine air pipe. After the condenser is activated, the condenser pipe condenses the exhaust gas in the fine air pipe, removing the moisture and condensate in the exhaust gas to improve the gas purity.

[0008] Preferably, the rear end of the thin air tube is connected to a second air vent, and the bottom of the second air vent is connected to a water outlet.

[0009] Preferably, the treatment cabinet is internally connected to a water filter cabinet, and the outlet pipe is fixedly connected to the water filter cabinet.

Water from the water tank enters the water collection box through the water inlet pipe. Then, the spray nozzles are activated, spraying the water in the collection box as a fine mist. This fine mist combines with the dust and fine particles in the exhaust gas and settles at the bottom of the filter cabinet. The wastewater is then removed by opening the cover. Clean water can be poured into the water tank by opening the cover. Moist gas is filtered by the filter plates through the vent pipe and enters the fine gas pipe. After the condenser is activated, the condenser pipe condenses the exhaust gas in the fine gas pipe, removing moisture and condensate to improve gas purity. This allows fine particulate matter in the exhaust gas to be extracted, preventing clogging of the filter and pipes, reducing system resistance, increasing processing efficiency, extending equipment lifespan, and reducing maintenance costs.

Five condensing pipes 15 are installed inside the condensing pipes 15. The fine air pipe 14 is located inside the condensing pipes 15. The waste gas from the landfill enters the filter cabinet 2 through the air inlet pipe 3. The garbage debris and particles in the waste gas are filtered by the filter plate 4. The water in the water tank 7 enters the water collection box 5 through the water inlet pipe 6. Then, the water spray head 8 is activated to spray the water in the water collection box 5 into a fine water mist. The fine water mist combines with the dust and fine particles in the waste gas and settles at the bottom of the filter cabinet 2. Then, the cover 9 is opened to remove the wastewater. Clean water can be poured into the water tank 7 by opening the box cover 10. The humid gas is filtered by the filter plate 11 when it passes through the air pipe 12 and enters the fine air pipe 14. After the condenser 13 is activated, the condensing pipes 15 condense the waste gas in the fine air pipe 14.

[0023] Please see Figures 1-4 In this embodiment, the rear end of the thin air pipe 14 is connected to the second air pipe 16, and the bottom of the second air pipe 16 is connected to the water outlet pipe 17.

[0025] During operation, waste gas from the landfill enters the filter cabinet 2 through the air inlet pipe 3. Waste debris and particles in the waste gas are filtered by the filter plate 4. Water in the water tank 7 enters the water collection box 5 through the water inlet pipe 6. Then, the water spray head 8 sprays the water in the water collection box 5 into a fine mist. The fine water mist combines with dust and fine particles in the waste gas and settles at the bottom of the filter cabinet 2. The wastewater is then removed by opening the cover 9. Clean water can be poured into the water tank 7 by opening the box cover 10. Moist gas is filtered by the filter plate 11 as it passes through the vent pipe 12 and enters the fine air pipe 14. After the condenser 13 is started, the condenser tube 15 condenses the exhaust gas in the thin air tube 14. The condensate formed by the condensation of the exhaust gas flows from the thin air tube 14 into the second ventilation tube 16, and then flows into the water filter tank 19 through the water outlet tube 17. At the same time, the condensed exhaust gas flows out from the air outlet tube 18. The sand filter layer 20 and the activated carbon layer 21 in the water filter tank 19 can remove suspended solids and some organic matter in the condensate. The required chemical agents can be added to the condensate through the agent box 25 and the agent tube 26 for coagulation or neutralization reaction. Then, the treated condensate can be taken out by opening the second cover 22.

[0026] Through the above steps, the exhaust gas enters the filter cabinet 2 through the air inlet pipe 3. The garbage debris and particles in the exhaust gas are filtered by the filter plate 4. The water in the water tank 7 enters the water collection box 5 through the water inlet pipe 6. Then, the water spray head 8 is activated to spray the water in the water collection box 5 into a fine mist. The fine mist combines with the dust and fine particles in the exhaust gas and settles at the bottom of the filter cabinet 2. Then, the wastewater is removed by opening the cover 9. Clean water can be poured into the water tank 7 by opening the box cover 10. The humid gas is filtered by the filter plate 11 when it passes through the air vent pipe 12 and enters the fine air pipe 14. After the condenser 13 is activated, the condenser pipe 15 condenses the exhaust gas in the fine air pipe 14, removing the moisture and condensate in the exhaust gas to improve the gas purity. This solves the problem in existing exhaust gas purification devices that fine particles in the exhaust gas not only clog the filters and pipes, increase the system resistance, and lead to a decrease in treatment efficiency, but also wear down equipment parts, shorten the service life of the equipment, and increase maintenance costs.
