Description

Technical Field

[0001] The utility model relates to the field of sewage extraction and exhaust air, in particular to a negative pressure type sewage extraction and exhaust air device. Background Technique

[0002] Dirty air refers to the air in the return airway with a relatively high degree of pollution after passing through the air-using places in the mine, also known as exhausted air and dirty air. Dirty air is the air current with a relatively high degree of pollution. Dirty air in the mine contains water vapor, and also contains a large amount of pollutants. These pollutants may be particulate matter, toxic gases, chemical substances, etc., resulting in pollutants also being contained in the water vapor. Dirty air will have a serious impact on human health, the environment and the ecosystem, and may cause problems such as respiratory diseases, heart diseases, and climate change.

[0003] Dirty air seriously affects human health and air quality. It is necessary to increase the purification function of the sewage extraction and exhaust air device to purify dirty air and ensure air quality. Most of the existing sewage extraction and exhaust air devices are large integrated devices with the purification function structure built-in, which is inconvenient to operate. Therefore, we propose a negative pressure type sewage extraction and exhaust air device. Content of the Utility Model

The bumps 8 are outside the packing box 5 and the structured packing ring box 6 and are in contact with the packing box 5 and the structured packing ring box 6. The packing box 5 and the structured packing ring box 6 can be removed from the notch 4. The bumps 8 are the guides for the movement of the packing box 5 and the structured packing ring box 6 and play a limiting role.

[0026] Furthermore, a first feed inlet 11 is provided on one side of the packing box 5. The side of the packing box 5 with the first feed inlet 11 is set as the top surface of the packing box 5. Mesh sheets 10 are provided on the front and back sides of the packing box 5. A handle 12 is fixedly connected to the center position of one side of the packing box 5.

[0030] Working principle: Place the negative-pressure sewage extraction and purification device at the position where sewage extraction and purification are required. Start the negative-pressure fan 1. The polluted air enters the housing 2 through the negative-pressure fan 1. The polluted air passes through the Pall rings 7 in the Pall ring box 6, reducing the speed of the polluted air and separating a certain amount of water vapor in the polluted air. The packing box 5 is filled with purification packing for purifying the pollutants in the polluted air. The polluted air continues to pass through the purification packing in the packing box 5, purifying the content of pollutants in the polluted air to within the standard range. The purified polluted air is discharged from the strip-shaped fence 9. The water vapor and chemical pollutants in the polluted air will damage the Pall rings 7. When replacing the Pall rings 7, operate the handle 12 to pull out the Pall ring box 6 from the housing 2 to replace the Pall rings 7. The same operation is performed for replacing the purification packing in the packing box 5, that is, operate the handle 12 to pull out the packing box 5 from the housing 2 to replace the purification packing.
