Description

Technical Field

[0001] This utility model relates to the field of environmental protection technology, specifically to a device for treating odor from pollution sources. Background Technology

[0002] Urban sewage treatment plants, garbage transfer stations, and kitchen waste treatment plants have many intermittent sources of odor pollution, such as sludge unloading and garbage unloading areas. These sources of odor pollution are generally enclosed places, and odor collection devices are installed in the plant to collect the odorous gases generated during the material unloading period.

[0003] Existing odor collection devices suffer from several drawbacks. Firstly, the intermittent odor source only emits foul gases during material unloading, while there is almost no odor during non-unloading periods. This results in low gas concentrations and excessively high collection air volumes during non-unloading times, leading to significant energy waste. Secondly, the design relies on average odor source intensity estimation, while odor emissions are concentrated and highly concentrated during unloading. This results in insufficient air exchange within the unloading area during this period, causing rapid dissipation of odorous gases and hindering effective collection. The resulting harsh working environment within the unloading area is also detrimental to operator work.

[0004] Therefore, it is necessary to provide a new odor treatment device for pollution sources to solve the above-mentioned technical problems. Utility Model Content

The online odor concentration monitoring instrument 5 is existing technology and is an instrument specifically used for real-time detection and monitoring of odor components and concentrations in the air, which will not be described in detail here. An exhaust hood 6 is installed at the bottom of the second air inlet pipe 3, located above the unloading area. An infrared sensor 7 is installed on the outside of the exhaust hood 6. The infrared sensor 7 is existing technology and monitors the unloading vehicle using the infrared sensor 7. After receiving the information that the unloading vehicle has entered, the infrared sensor 7 performs odor treatment. The filter plate 8 installed inside the collection box 2 filters out harmful substances in the odor. A pull plate 9 is fixedly connected to one side of the filter plate 8. Pulling the pull plate 9 causes the filter plate 8 to slide inside the collection box 2, which facilitates the subsequent disassembly and replacement of the filter plate 8. A support frame 10 is fixedly connected to the top of the collection box 2. A support plate 11 is set at the bottom of the support frame 10.

The air inlet end of the fan 20 is connected to one side of the collection box 2 through a pipe. The unloading vehicle is monitored by an infrared sensor 7. After the infrared sensor 7 receives the information that the unloading vehicle has entered, it starts the fan 20 and adjusts the fan 20 to a high-concentration operation mode. In this condition, the first solenoid valve 16 is closed and the second solenoid valve 4 is open. The odor generated during unloading is directly absorbed through the exhaust hood 6 and the second air inlet pipe 3. The odor is collected through the collection box 2 and monitored by the online odor concentration monitoring instrument 5. When the odor concentration monitoring value is less than 50, the fan 20 is adjusted to a low-concentration operation mode. In the low-concentration operation mode, the first solenoid valve 16 is open and the second solenoid valve 4 is closed. The odor in the unloading area is absorbed through the air inlet branch pipe 17 and the air inlet head 18. The low-concentration operation mode increases the odor adsorption range and improves the odor adsorption treatment effect. This device can save unnecessary energy consumption by automatically adjusting the operating frequency of the fan 20, and has good economic efficiency.

[0026] A cylinder 21 is mounted on the top of the support frame 10. The piston rod of the cylinder 21 is fixedly connected to a fixing frame 22.

The starting cylinder 21 drives the fixed frame 22 and the support plate 11 to move downward, so that the cleaning brush 14 contacts the filter plate 8. The starting motor 12 drives the fixed plate 13 and the cleaning brush 14 to rotate. The filter plate 8 can be cleaned by the cleaning brush 14. One set of nozzles 27 of the water outlet pipe 26 faces the filter plate 8, which can disinfect and clean the filter plate 8 and the odor. The other set of nozzles 27 of the water outlet pipe 26 faces the cleaning brush 14, which can clean the cleaning brush 14.

[0027] Working Principle: During operation, this device monitors the unloading vehicle using an infrared sensor 7. Upon receiving information that the unloading vehicle has entered, the infrared sensor 7 activates the blower 20, adjusting it to a high-concentration operating mode. In this mode, the first solenoid valve 16 is closed, and the second solenoid valve 4 is open. The odor generated during unloading is directly absorbed through the exhaust hood 6 and the second air inlet pipe 3. The odor is collected by the collection box 2, and the ambient odor is monitored by the online odor concentration monitoring instrument 5. When the odor concentration is less than 50, the blower 20 is adjusted to a low-concentration operating mode. In this mode, the first solenoid valve 16 is open, and the second solenoid valve 4 is closed. The odor in the unloading area is absorbed through the air inlet branch pipe 17 and the air inlet head 18. The low-concentration operation mode improves the odor adsorption range and enhances the odor adsorption treatment effect. This device can save unnecessary energy consumption by automatically adjusting the operating frequency of the fan 20, thus having good economic efficiency. The starting cylinder 21 drives the fixed frame 22 and the support plate 11 to move downwards, so that the cleaning brush 14 contacts the filter plate 8. The starting motor 12 drives the fixed plate 13 and the cleaning brush 14 to rotate. The cleaning brush 14 can clean the filter plate 8. One set of water outlet pipes 26 has nozzles 27 facing the filter plate 8, which can disinfect and clean the filter plate 8 and the odor. Another set of water outlet pipes 26 has nozzles 27 facing the cleaning brush 14, which can clean the cleaning brush 14. Pulling the pull plate 9 causes the filter plate 8 to slide inside the collection box 2, which facilitates the subsequent disassembly and replacement of the filter plate 8.
