Description
Technical Field

[0002] As air pollution worsens and environmental protection becomes increasingly severe, the country and various provinces and cities have successively introduced stricter exhaust emission standards to gradually reduce the content of pollutants in exhaust gas, which requires more efficient pollution control equipment. Among them, wet dust removal with ultra-low emission is a relatively difficult field.
[0003] Ultra-low emission wet dust removal has problems such as exhaust gas carrying liquid and back mixing. The salt and particulate matter in the droplets cause the exhaust gas indicators to remain high. It can only be equipped with complex dust removal equipment such as wet electricity, and the operating costs are high. At present, it is difficult to meet the requirements of ultra-low emission dust removal by wet dust removal alone. Moreover, during operation, the existing dust collector can only filter the gas in a single way, which cannot improve the dust removal efficiency. At the same time, it cannot automatically equalize the gas that needs dust removal, and thus cannot effectively remove dust from the gas. Utility Model Content

The water collecting box 12 is symmetrically arranged on both sides of the overflow trough 13. The air intake pipe 18 is fixedly connected to the top of the air equalization chamber 11. The bottom of the air equalization chamber 11 is arranged on the middle upper surface of the water collecting box 12. A baffle 114 is evenly arranged inside one end of the air intake pipe 18. A rotating drum 115 is rotatably clamped inside the other end of the air intake pipe 18. A rotating disk 19 is fixedly installed on the outer surface of one end of the rotating drum 115. The outer surface of the rotating disk 19 is rotatably connected to a connecting arm 110.
[0026] One end of the connecting arm 110 is rotatably connected to a tooth plate 111, and a rotating shaft 113 is rotatably installed on the bottom end of the baffle plate 114. An air equalizing plate 17 is fixedly connected to the bottom of both ends of the rotating shaft 113. A transmission gear 112 is fixedly installed on the outer surface of one end of the rotating shaft 113. A discharge pipe 14 is provided at the bottom center of the overflow trough 13. A foam collecting orifice plate 15 is fixedly installed inside the water collecting tank 12. A spray pipe 16 is provided inside the water collecting tank 12 and below the foam collecting orifice plate 15. The connecting arm 110 is meshed and connected with the transmission gear 112 through the tooth plate 111.
[0027] A spray pipe 16 is also provided at the bottom of the gas-liquid separator 2, a side observation port 32 is provided on the middle outer surface of the protective cover 3, an air outlet 31 is provided at the top center of the protective cover 3, a filter plate 41 is provided inside the circulating water tank 4, a water pump 42 is fixedly installed on the outer surface of one end of the circulating water tank 4, a delivery pipe is connected to the outer surface of the water pump 42, and the water pump 42 is fixedly connected to one end of the spray pipe 16 through the delivery pipe.
[0028] The utility model provides a limit frame on the upper outer surface of the air equalizing chamber 11, and the tooth plate 111 is slidably plugged with the limit frame, which can limit the sliding of the tooth plate 111. A nozzle is provided on the outer surface of the spray pipe 16, which can make water and dust fully contact to achieve the dust removal effect.
[0029] Overflow ports are provided on both sides of the overflow trough 13 of the utility model, so that the dirt captured by the foam can be cleaned; glass observation ports are provided at both ends of the overflow trough 13, so that the staff can conveniently see the situation inside the dust collector; the bottom end of the discharge pipe 14 is fixedly connected to the top of the filter plate 41, so that the overflowing dirt can be transported to the circulating water tank 4 for recycling; the bottom end of the water collecting tank 12 is connected to the top of the circulating water tank 4, so that the sewage flushed from the bottom of the gas-liquid separator 2 can be collected; the material of the air equalizing plate 17 is lightweight plastic, so that the air equalizing plate 17 can be ensured to swing back and forth stably.
[0030] The working principle of the utility model is as follows: first, the gas to be dusted is transported to the interior of the air equalizing chamber 11 through the air intake pipe 18, and at the same time, the gas will blow the rotating drum 115 to rotate. When the rotating drum 115 rotates, it will drive the connecting arm 110 to swing cyclically through the turntable 19 at one end. During the swinging process, the connecting arm 110 will drive the toothed plate 111 at one end to reset and slide, and at the same time, the toothed plate 111 will drive the transmission gear 112 meshing at the bottom to reciprocate, so that the transmission gear 112 drives the air equalizing plate 17 through the rotating shaft 113 to swing back and forth inside the air equalizing chamber 11, so that the air entering through the air intake pipe 18 The gas inside the equalizing chamber 11 will be evenly distributed inside the equalizing chamber 11 under the reciprocating swing of the rotating shaft 113. At the same time, the spray pipe 16 at the lower part of the foam collecting orifice plate 15 will spray water upward through the nozzle on the outer surface of the spray pipe 16 under the delivery of the water pump 42, and a layer of water film will be formed on the surface of the foam collecting orifice plate 15. Therefore, the gas rushes down at a high speed and contacts the foam collecting orifice plate 15, which will cause the gas to contact the foam collecting orifice plate 15 to generate a large amount of foam, so that the dust in the gas can fully contact with the circulating water and be captured and melted into the water mist droplets, which can improve the dust removal and foam removal efficiency. Oil or dust with a density less than that of water will float on the water surface inside the water collecting tank 12 after being captured, and then as the liquid level inside the water collecting tank 12 rises, the dust and oil film on the water surface will flow into the overflow tank 13 through the overflow port, and the gas after dust removal and foam removal will rise into the demisting chamber through the top of the overflow tank 13, and will be discharged from the air outlet after further separation by the gas-liquid separator 2, so as to achieve particulate matter ≤10mg / m3, and the spray pipe 16 can flush the bottom of the gas-liquid separator 2 to prevent dirt from adhering to the bottom of the gas-liquid separator 2, thereby ensuring the normal filtration of the gas-liquid separator 2; at the same time A multi-stage filter plate 41 is arranged inside the circulating water tank 4, which can filter the sewage collected inside the circulating water tank 4, so that dust and oil sediments or floating objects are separated and removed, and the purified water can be circulated for flushing the foam capture orifice plates 15 and 5, thereby ensuring that the foam capture orifice plates 15 and the gas-liquid separator 2 are normally filtered without being blocked by sediments. Through the coordinated operation of the foam capture and dust removal component 1, the gas-liquid separator 2, the protective cover 3 and the circulating water tank 4, the incoming gas can be evenly distributed, the efficiency of dust removal and foam removal is improved, and the gas-liquid separator 2 can further play a role in foam removal.

All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
