Description

Technical Field

[0001] The utility model belongs to the technical field of air pollution prevention and control, in particular to an air pollution prevention and control device. Background Art

[0002] When the air pollution treatment device is treating dust and gaseous pollutants in the air, dust will cause the external filter to become clogged. At the same time, when treating the atmosphere, moisture in the atmosphere will adhere to the filter installed inside the device, thereby affecting the filtering effect of the filter.

[0003] A Chinese patent with publication number CN117258455A discloses an air pollution control device for environmental management, including a box body and a cleaning mechanism arranged in the box body; the cleaning mechanism includes a dust removal box, a plurality of first cleaning components, and a driving component; the two ends of the dust removal box are respectively connected to the air inlet and the air outlet; the first cleaning component includes a first dust removal plate and a first dust removal part; the first dust removal plate is slidably connected to the dust removal box; the driving component is used to drive the first dust removal plate to reciprocate vertically; the first dust removal part includes a first transverse block, a first brush and a first motion unit for driving the first transverse block to reciprocate vertically.

[0004] In the current existing technology, when the atmosphere is tested, it is generally installed around garbage dumps, chemical plants and other places that produce polluted gases. The surrounding areas of these factories contain a large number of harmful microorganisms, harmful particles and other impurities that have not been burned cleanly. When monitoring air pollution, the air will be absorbed and filtered to observe the content of dust and impurities in the air and whether it contains harmful, easily spread and other substances that are harmful to the human body. However, after the impurities are filtered out, the internal gas will be directly discharged. These odorous gases will contain some bacterial microorganisms. After being discharged, they will accumulate around the equipment and be inhaled by employees or passers-by, causing bacterial infection, resulting in the problem that the equipment can only filter impurities but cannot purify harmful gases.

[0005] To this end, the utility model provides an air pollution prevention and control device. Utility Model Content

When the rotating sleeve 145 rotates, it cooperates with the curvature on the surface of the downward pressure wind arc sheet 147 to absorb and guide the external wind source into the interior of the compression tube 141 during rotation.

[0067] Furthermore, if Figure 2 - Figure 5 As shown, the position of the pushing fan blade 146 is set on the outer surface of the rotating sleeve 145, and the bottom surface of the pushing fan blade 146 is movably overlapped on the top surface of the horn head 142, the position of the downward pressure wind arc piece 147 is set at the outer bottom edge position of the rotating sleeve 145, and the outer surface of the downward pressure wind arc piece 147 is movably overlapped on the inner wall surface of the compression tube 141, and one end of the air guide tube 13 is fixedly connected to the outer surface of the compression tube 141, a closing door 148 is set on the outer surface of the exhaust gas collecting tank 14, and a lock buckle 149 is set on the outer surface of the exhaust gas collecting tank 14 and on the outer surface of the closing door 148.

When the external wind force is small, cooperate with the fan to absorb the gas inside the exhaust gas collection tank 14, and guide the external air into the interior of the exhaust gas collection tank 14.

[0072] After the gas inside the exhaust gas collection tank 14 is filtered, it is discharged into the interior of the heat-conducting aluminum shell 122, and the flame heads 124 on the inner walls on both sides of the heat-conducting aluminum shell 122 are used to spray flames to burn the incoming air. The high-temperature gas is used to perform a secondary high-temperature incineration on the odorous gas and harmful substances that have not been filtered out inside the gas to clean up harmful microorganisms in the gas. The high-temperature heat generated during the high-temperature incineration will be transferred out through the heat-conducting aluminum shell 122, and the cavity on the outer surface of the heat-conducting aluminum shell 122 will be used to accumulate the hot gas. As the gas continues to accumulate and the heat rises, the heat is transferred into the interior of the compression tube 141 through the air guide pipe 13 and mixed with the incoming gas. The heat source is used to dry the water vapor in the air at high temperature to prevent impurities from adhering to the surface of the filter due to water vapor and causing caking and clogging.

[0073] The gas after high-temperature incineration is diverted out through the rectangular air duct 129, and is contacted with the flowing hot air by the cooling aluminum tube 1210 on the outer surface of the rectangular air duct 129, and the heat source is absorbed by the material of the cooling aluminum tube 1210. At the same time, the water source inside the water tank 126 is absorbed by the water pump 127, and the water source is sprayed from the top of the rectangular air duct 129 in cooperation with the water pipe 128. The low temperature of the water source is used to absorb the hot air on the surface of the rectangular air duct 129 and the cooling aluminum tube 1210, so as to cool the hot air before discharging it. When the water source is flowing, it is cooled by the water pipe 128.

[0074] After a period of time, the semicircular filter shell a7 is peeled off and the sponge filter layer a13 is taken out and replaced. The types of impurities inside the sponge filter layer a13 are observed, and harmful substances in the air are detected. After replacing the new sponge filter layer a13, the semicircular filter shell a7 is overlapped on the top surface of the raised air permeable layer a4, and the position of the semicircular filter shell a7 is limited by the sliding limit groove a6. When the two semicircular filter shells a7 are docked, they are docked with the docking joint a8 and the docking groove a9 to fix their position. The separated and guided wind source cooperates with the two semicircular filter shells a7 to filter the gas in layers.
