Description

Technical Field

[0001] The utility model relates to the technical field of waste gas filtration, in particular to a Fenqiuli cyclone cabinet. Background Art

[0002] During the paint spraying process, paint exhaust gas treatment is crucial. Current mainstream methods, such as activated carbon adsorption combined with catalytic combustion (RCO) or zeolite rotors combined with regenerative thermal oxidation (RTO) combustion, while effective, still face challenges. Activated carbon and zeolite rotors primarily filter out solid impurities, resulting in a high level of solid matter remaining in the exhaust gas after combustion, posing a significant environmental pollution threat. To this end, the Chinese utility model patent, published with the publication number CN215692692U, proposes a "Fenqiuli filtered water cabinet." After exhaust gas passes through the water film produced by the water film generator, the cabinet comprises a filter chamber, a dehydration chamber, and a water tank. The filter chamber and the dehydration chamber are connected, and the water tank is connected to the filter chamber. The filter chamber is provided with an air inlet, and the filter chamber is equipped with a water film generator. The dehydration chamber is provided with an air intake outlet, and the dehydration chamber is equipped with a reversing dehydration device. Exhaust gas enters the filter chamber from the air inlet, passes through the water film produced by the water film generator, and reaches the dehydration chamber. Exhaust gas entering the dehydration chamber is dehydrated by the reversing dehydration device and then sucked out through the air intake outlet. The water tank collects water in the filter chamber and is equipped with a water circulation device, which supplies water from the water tank to the water film generator. Its exhaust gas filtration method mainly relies on the wastewater passing through the water film, and the filtration effect needs to be improved. Utility Model Content

[0036] Please refer to Figures 1-4 A Fenkhuri cyclone cabinet comprises a primary water film scroll chamber 1 and a secondary separation bin 2 in communication with the primary water film scroll chamber 1.

[0037] The primary water film scroll chamber 1 has a first air inlet 101, and the primary water film scroll chamber 1 has a water film generating device 102 thereon, and the water film generated by the water film generating device 102 is located on the flow route of the exhaust gas flowing from the first air inlet 101 into the primary water film scroll chamber 1 and from the primary water film scroll chamber 1 to the secondary separation bin 2, wherein the exhaust gas passes through the water film when passing through the flow route of the exhaust gas.

[0038] The secondary separation bin 2 has a vertically arranged cylindrical bin body 201, a second air inlet 202 tangent to the circular inner side surface of the cylindrical bin body 201, an air outlet 203 in communication with the cylindrical bin body 201, a spraying device 204, and a drain 205 in communication with the cylindrical bin body 201.

[0039] The cylindrical bin body 201 is in communication with the primary water film scroll chamber 1 through the second air inlet 202, the air outlet 203 is higher than the second air inlet 202, the spraying device 204 has a spraying nozzle 2041 for spraying in the cylindrical bin body 201 and a water guide pipe 2042 in communication with the spraying nozzle 2041, wherein the spraying height of the spraying nozzle 2041 is higher than the second air inlet 202, and the drain 205 is lower than the second air inlet 202.

[0040] After the exhaust gas passes through the water film generated by the water film generating device 102, the solid matter in the exhaust gas and other substances dissolved in water are filtered and dissolved by the water film, forming the first filtration of the exhaust gas; thereafter, the exhaust gas enters the cylindrical chamber 201 from the second air inlet 202 in a direction tangent to the circular inner side of the cylindrical chamber 201; through the circular rotation guide of the circular inner side of the cylindrical chamber 201 and the arrangement of the air outlet 203 higher than the second air inlet 202, the exhaust gas can form upward rotating centrifugation in the cylindrical chamber 201, and during the upward rotating centrifugation, the exhaust gas collides with the downwardly sprayed water body, so that the exhaust gas can be better filtered in the cylindrical chamber 201. Through the rotating centrifugation, the exhaust gas can stay in the water spray for a longer time before being discharged, and through the water spray combination, the solid materials in the exhaust gas are in contact with water to increase the weight, which is more easily separated during the rotating centrifugation.

[0050] In some embodiments, the filter 401 is a filter mesh plate,

[0051] In some embodiments, the water body circulation assembly 402 comprises a water pump and a corresponding water pipe.
