Chemical waste gas often contains many types of pollutants, with complex physical and chemical properties and different toxicity, which seriously pollutes the environment and affects human health. The composition of chemical waste gas produced by different chemical production industries varies greatly. For example, the waste gas produced by the chlor-alkali industry mainly contains chlorine, hydrogen chloride, vinyl chloride, mercury, acetylene, etc., and the waste gas produced by the nitrogen fertilizer industry mainly contains nitrogen oxides, urea dust, carbon monoxide, ammonia, sulfur dioxide, methane, etc. The tail gas emitted by chemical plants often has a harmful effect on the environment and human health. Purification measures should be taken before it is discharged into the atmosphere. Commonly used waste gas purification methods are: absorption method, adsorption method, condensation method and combustion method.

The electromagnet is energized in the reverse direction to push the permanent magnetic pin to reset, and the regenerated activated carbon is placed at the top, thereby achieving the reordering of multiple filtering mechanisms and further ensuring the activated carbon adsorption effect.

The telescopic rod 9 is shortened, driving the bottom filter housing 161 to move to just above the circular groove, and the driver 5 works to drive the filter housing 161 to move downward, so that the activated carbon 162 is slowly immersed in the activated carbon regeneration liquid, and the activated carbon 162 is regenerated, thereby solving the problem that the existing activated carbon will be inactivated by some substances in the exhaust gas after long-term use and will no longer be able to treat the exhaust gas.

[0023] Among them, the upper ends of the threaded rods 6 are rotatably connected to the shell 17, the upper ends of the sliding rods 8 are fixedly connected to the shell 17, the lower ends of the sliding rods 8 are fixedly connected to the base 1, the sliding block 7 is adapted to the shell 17, the limit ring 15 is fixedly connected to the inner wall of the shell 17, the driving motor 121 is fixedly connected to the inner wall of the installation cavity 11, the rotating rod 122 and the rotating rod 2 126 are rotatably connected to the rectangular block 10, the rack 133 is meshed with the half gear 127, the end of the compression spring 134 away from the rack 133 is fixedly connected to the fixed shell 131, the arc groove 164 is adapted to the semi-arc block 136, the rectangular plate 165 is adapted to the connecting cavity 137, the circular groove formed by the right side of the fixed block 14 and the sealing slider 3 is filled with an appropriate amount of activated carbon regeneration liquid, the circular groove is adapted to the filter shell 161, and the upper surface of the sealing slider 3 is connected to the shaking mechanism 13 is adapted, and its function is to extend the telescopic rod 9 to drive the semi-arc block 136 to move until it is completely located inside the arc groove 164, and the electromagnet 138 is energized to adsorb the permanent magnetic pin 166 to slide outward, and finally a part of the permanent magnetic pin 166 is located inside the connecting cavity 137, and a part is still in contact with the rectangular plate 165. The telescopic rod 9 is shortened to achieve the clamping of the bottom activated carbon 162. After it is regenerated, the driver 5 works to drive the activated carbon 162 to move up until the filter housing 161 is at the top, and then the telescopic rod 9 is extended to make the filter housing 161 contact with the left inner wall of the shell 17, and the electromagnet 138 is reversely energized to push the permanent magnetic pin 166 to reset, and place the regenerated activated carbon 162 at the top, thereby achieving the reordering of multiple filtering mechanisms 16, and further ensuring the adsorption effect of the activated carbon 162.

[0024] Working principle: Before using the present invention, a proper amount of activated carbon regeneration liquid is placed inside the circular groove, and the telescopic rod 9 is in the shortest state; When the present invention is used, the tail gas pipe of the chemical raw material to be processed is connected to the air inlet interface 19, and the air outlet interface 18 is connected to the subsequent processing device. The tail gas will flow upward and be adsorbed and filtered by multiple activated carbons 162. When the lowest activated carbon 162 is inactivated and cannot play the role of adsorption and filtration, the introduction of the tail gas is suspended, and then the driver 5 works to drive the threaded rod 6 to rotate, so that the sliding block 7 slides up and down. When the semi-arc block 136 is aligned with the lowest arc groove 164, the driver 5 stops working, and the telescopic rod 9 extends to drive the semi-arc block 136 to move until it is completely located inside the arc groove 164. The electromagnet 138 is energized to attract the permanent magnetic pin 166 to slide outward, and finally a part of the permanent magnetic pin 166 is located inside the connecting cavity 137, and a part is still in contact with the rectangular plate 165. The telescopic rod 9 is shortened until the bottom filter housing 161 is located just above the circular groove, and the remaining filter mechanism 16 will slide downward, and the driver 5 will work to drive the filter housing 161 to move downward, so that the activated carbon 162 is slowly immersed in the activated carbon regeneration liquid, so that the inactivated substances of the activated carbon 162 react. During the process, the shaking mechanism 13 will contact the sealing slider 3 and drive the sealing slider 3 to slide downward and squeeze the reset spring 4; When the substance that inactivates the activated carbon 162 is completely reacted, the driver 5 works to drive the sliding block 7 to move upward appropriately, so that there is a certain distance between the lower surface of the filter housing 161 and the liquid surface of the activated carbon regeneration liquid, and the driving motor 121 works to drive the driving gear 123 to rotate. The rotation of the driving gear 123 will drive the meshing intermediate gear 124 to rotate, and the rotation of the intermediate gear 124 will drive the pinion 125 to rotate. The pinion 125 drives the half gear 127 to rotate through the rotating rod 126. When the half gear 127 is meshed with the rack 133, the half gear 127 will drive the rack 133 and the rectangular plate 165 to slide upward or downward until the half gear 127 is meshed with the rack 133. The rack 133 is in a critical state of meshing. At this time, the compression spring 134 at one end of the rack 133 is in a compressed state, and the compression spring 134 at the other end is in a stretched state. The half gear 127 continues to rotate, and the rack 133 is pushed by the compression springs 134 at the upper and lower ends, thereby driving the activated carbon 162 and the filter housing 161 to shake up and down, and the activated carbon regeneration liquid remaining on the activated carbon 162 and the filter housing 161 is thrown off. In this way, after the activated carbon regeneration liquid remaining on the activated carbon 162 and the filter housing 161 is completely dried, the half gear 127 stops rotating. At this time, the half gear 127 is meshed with the rack 133 and the rack 133 is located in the middle position of the fixed housing 131. The driver 5 works, driving the activated carbon 162 to move upward until the filter housing 161 is at the top, and then the telescopic rod 9 is extended to make the filter housing 161 contact the left inner wall of the shell 17, and the electromagnet 138 is energized in the reverse direction to push the permanent magnetic pin 166 to reset, placing the regenerated activated carbon 162 at the top, and then the telescopic rod 9 is shortened and reset.
