Description

Technical Field

[0001] The invention relates to the technical field of plasma organic waste gas purification, and in particular to a plasma organic waste gas purifier with a multi-stage filtering function. Background Art

[0002] Plasma chemistry is an interdisciplinary subject involving high-energy physics, discharge physics, discharge chemistry, reaction engineering, high-voltage pulse technology and other fields. Using plasma to treat various pollutants has become one of the hot research topics at home and abroad. Compared with other pollution control technologies, plasma method has the characteristics of short treatment process, high efficiency, low energy consumption and wide application range. Plasma can be used to treat waste gas, wastewater, solid waste, sludge and even radioactive waste. When low-temperature plasma is used to decompose gaseous pollutants, high-energy electrons in the plasma play a decisive role.

[0003] For example, the low-temperature plasma waste gas purification device and purification method with publication number CN117180909A, by setting a cleaning structure, when the waste gas reaches the inside of the device body during use, it will first be filtered through the filter plate, and large particles will adhere to the surface of the filter plate. After the filter plate has been used for a certain period of time, the output is made through the motor, so that the motor drives the shaft to rotate. When the shaft rotates, it will drive the wheel and the drive belt to rotate, so that the threaded rods on both sides can rotate synchronously. When the threaded rods rotate, they will drive the mounting plate and the scraper block on the right side of the control block to move, so that the scraper block can remove the filter plate surface. The dirt on the surface is scraped off to avoid clogging of the filter plate. However, in actual use, the surface of the filter plate is cleaned by moving the scraper. During the cleaning process, the dust on the filter plate will be scraped off, which will cause dust. After the dust is generated, the cleaned dust cannot be collected, and the dust will remain inside the device body, which will affect the cleanliness of the filter plate in the future. If dust is generated during the cleaning process, the dust will float everywhere and may adhere to the outside of other parts, causing the parts to become dirty and increasing the wear caused by the operation of the parts. There are certain usage defects.

[0004] Therefore, we proposed a plasma organic waste gas purifier with multi-stage filtration function to solve the above problems. Summary of the invention

A cleaning component is provided on one side of the inner part of the outer shell. The exhaust gas can enter the inner part of the outer shell through the left side of the outer shell.

[0031] Working principle: When using the plasma organic waste gas purifier with multi-stage filtration function, first, according to Figure 1-Figure 9As shown, the exhaust gas can enter the interior of the housing 1 through the left side of the housing 1, and the exhaust gas is filtered in multiple stages through the filter 104 and the activated carbon filter layer 103. After that, the exhaust gas enters the plasma generator 101 through the gas collecting cover 102 for purification. In the process of generating plasma, the instantaneous high energy generated by the high-frequency discharge of the plasma generator 101 is enough to open the chemical energy of these harmful gas molecules and decompose them into single atoms or harmless molecules; the plasma contains a large number of high-energy electrons, positive and negative ions, excited particles and free radicals with strong oxidizing properties. The active particles collide and combine with some odor molecules, and under the action of the electric field, the odor molecules are in an excited state. When the energy obtained by the odor molecules is greater than the combination of their molecular bond energy, the chemical bonds of the odor molecules are broken and directly decomposed into single atoms to form harmless gas molecules. At the same time, a large amount of active radicals such as OH, HO2, O and highly gasifiable O3 are generated, which react chemically with harmful gas molecules to eventually generate harmless products. After long-term use, the filter 104 needs to be cleaned. When cleaning the filter 104, the drive motor 202 is started to drive the reciprocating screw 203 to rotate, which can drive the movable block 205 to move back and forth, so as to drive the movable plate 207 to move up and down. During the movement of the movable plate 207, the limit block 206 is driven to slide on the limit rod 204 for limiting, so that the cleaning plate 2071 can be driven to move up and down, and the filter 104 is cleaned by the bristles on the cleaning plate 2071. While the drive motor 202 is running, the first pulley 209 and the second pulley 210 can cooperate to drive the rotating shaft 208 to rotate, and the rotating shaft 208 After the rotation, the cooperation between the positioning strip 213 and the positioning groove 214 can drive the rotating sleeve 212 to rotate. During the movement of the movable plate 207, the rotating sleeve 212 can be driven to move together. The meshing of the first bevel gear 215 and the second bevel gear 217 can drive the connecting shaft 216 to rotate. After the connecting shaft 216 rotates, the third bevel gear 221 and the fourth bevel gear 222 can drive the rotating rod 220 to rotate, so that the operation of the driving motor 202 can accelerate the transmission of the rotating rod 220, thereby forming a negative pressure state inside the cylinder 218. The dust generated during the cleaning process can enter the cylinder 218 through the air intake hood 230 and the connecting pipe 227. Under the rotation of the rotating blade 223, the exhaust gas can enter the breathable dust bag 226 through the telescopic pipe 224 and the mounting pipe 225 for collection; The movable plate 207 can drive the column 239 on the mounting frame 238 to slide inside the guide groove 2392 during the up and down reciprocating movement. The column 239 can drive the moving rod 234 to move back and forth through the sliding connection with the guide groove 2392. The reciprocating movement of the moving rod 234 can drive the rack 236 on the mounting rod 235 to reciprocate. After the reciprocating movement of the rack 236, the movable rod 232 can be driven to reciprocate by meshing with the rotating gear 237, and then the air intake hood 230 can be driven to reciprocate, so that the air suction range of the air intake hood 230 can be expanded, so that the dust can be fully absorbed. During the up and down reciprocating movement of the movable plate 207, the two moving rods 234 can reciprocate back and forth, and the moving rod 234 can drive the cleaning plate 2071 to reciprocate back and forth through the connecting plate 240. During the movement, the cleaning plate 2071 drives the moving block 243 to slide on the guide rod 242 to guide the movement of the movable plate 207. Then, the movable plate 207 reciprocates up and down to drive the cleaning plate 2071 to clean the filter 104 up and down. At the same time, the cleaning plate 2071 can reciprocate back and forth, so that the bristles on the cleaning plate 2071 can continuously move back and forth to avoid the bristles from moving in the same direction and causing the bristles to bend, and the reciprocating movement of the cleaning plate 2071 back and forth can improve the cleaning effect of the cleaning plate 2071.
