[0002] In chemical plants, petrochemicals, refining, chemical raw materials and chemical products, a large amount of ozone is produced. Ozone cannot be directly discharged. Ozone is a harmful gas at high concentrations, which has adverse effects on human health and the environment. It can irritate the respiratory tract, cause eye and skin discomfort, and even affect the growth of crops.

[0003] At present, the treatment of ozone in chemical waste gas pollutants is generally high-temperature decomposition and ozone destruction catalyst decomposition. High-temperature decomposition requires ozone to be continuously in a high-temperature environment, which has limited efficiency.

[0004] Ozone destruction catalysts are consumables, mainly made of active ingredients such as manganese dioxide, copper oxide, and aluminum oxide. Ozone molecules are adsorbed on the active sites on the catalyst surface to form adsorbed ozone molecules. The ozone molecules gradually decompose into oxygen and elemental oxygen. However, after long-term use, the catalyst will gradually deactivate, affecting the quality of ozone decomposition.

[0005] In the continuous production operation of chemical industry, the sustainable effect of existing ozone decomposition devices on ozone decomposition is limited. After the ozone destruction catalyst destroys the ozone reaction, the catalyst will gradually become inactivated, resulting in a gradual decrease in the decomposition efficiency of ozone, so that the efficiency and reliability of ozone decomposition will gradually be affected. Therefore, a chemical pollutant decomposition and treatment device is proposed to provide a set of efficient, reliable and sustainable ozone destruction decomposition devices for ozone pollutants generated in the chemical industry, so that ozone can be quickly and efficiently decomposed from O3 to O2, and the ozone destruction catalyst can be continuously cleaned and restored to activity, and continuously maintain a good state to destroy and decompose ozone, which limits the frequency of operations that require shutdown for catalyst replacement and maintenance, thereby ensuring the efficiency and quality of chemical ozone pollutant decomposition and treatment.

[0066] A dust collecting device is provided on one side of the treatment tank 1 close to the ultra-high temperature chamber 12, and the dust collecting device includes a dust collecting box 6 and an inclined semicircular dust guide plate 61. The dust collecting box 6 is fixed to the outside of the treatment tank 1, and the inclined semicircular dust guide plate 61 is away from the bottom of the ozone destruction catalyst 9 and is arranged in the ultra-high temperature chamber 12.

The dust outlet 62 is respectively located at the top of the lower partition plate 15 and the inclined semicircular dust guide plate 61. The dust collecting box 6 has a filter valve 7 connected to its cover.

[0068] During use, after the semicircular lifting plate 124 descends, the bottom of the semicircular lifting plate 124 will press down on the inner sleeve 1202, so that the air inlet docking port 1204 of the inner sleeve 1202 overlaps and docks with the air supply docking port 1206 of the sleeve 1201, so that the high-pressure air in the pressure tank 4 can enter the air inlet cavity 1203, and be discharged into the upper air box 127 through the exhaust port 1205, and the jet hole 128 of the upper air box 127 will spray the bottom, so that the high-pressure air discharged from the jet hole 128 will carry the heat from the surface of the ceramic heating tube 129 to spray on the surface of the ozone destruction catalyst 9, so that the impurity particles brushed off in the air hole 91 will fall onto the inclined semicircular dust guide plate 61, and enter the dust collecting box 6 through the dust discharge port 62.

[0069] A pressure tank 4 is provided at one side of the processing tank 1 , an exhaust end of the pressure tank 4 is connected to the air supply interface 1206 through a pipeline, and an air intake end of the pressure tank 4 is connected to an air compressor 5 .

[0071] During operation, the motor 131 drives the rotating column 132 to rotate, so that the ozone destruction catalyst 9 connected to the rotating column 132 rotates, so that the ozone destruction catalyst 9 can continuously move in the medium-high temperature chamber 11 and the ultra-high temperature chamber 12, so that after the ozone destruction treatment in the medium-high temperature chamber 11, the ozone destruction catalyst 9 moves to the ultra-high temperature chamber 12 to remove water vapor at high temperature to restore activity, and during the restoration of activity, a synchronous cleaning operation is performed to clean the impurity particles adhered to the surface of the holes of the ozone destruction catalyst 9, so that the ozone destruction catalyst 9 can maintain a good ozone destruction effect after being transferred back to the medium-high temperature chamber 11, thereby improving the reliability and sustainability of the ozone decomposition treatment;

[0072] When the motor 131 drives the rotating column 132 to rotate, the third synchronous wheel 133 on the driving end of the motor 131 will drive the second synchronous wheel 123 to rotate, and at the same time, the first synchronous wheel 122 drives the reciprocating screw rod 121 to rotate. After the reciprocating screw rod 121 rotates, the screw rod sleeve 126 will drive the semicircular lifting plate 124 to reciprocate on the reciprocating screw rod 121, so that the cleaning rod 125 on the semicircular lifting plate 124 can be reciprocated and lifted, so that the reciprocating air hole 91 of the ozone destruction catalyst 9 above can be reciprocated by the cleaning rod 125. The inner wall of the air hole 91 is cleaned by pulling and pulling. Since the diameter of the third synchronous wheel 133 is larger than that of the second synchronous wheel 123, the rotation speed of the reciprocating screw rod 121 is higher than the rotation frequency of the rotating column 132. The third synchronous wheel 133 is larger than the diameter ratio of the second synchronous wheel 123. The cleaning rod 125 is set according to the actual cleaning demand of the air hole 91. During this period, the cleaning rod 125 is inserted into the air hole 91, descends and exits the air hole 91, and enters the next group of air holes 91 again. The frequency is consistent;

[0073] After the semicircular lifting plate 124 is lowered, the bottom of the semicircular lifting plate 124 presses down the inner sleeve 1202, so that the air inlet interface 1204 of the inner sleeve 1202 overlaps with the air supply interface 1206 of the sleeve 1201, so that the high-pressure air in the pressure tank 4 can enter the air inlet cavity 1203, and is discharged into the upper air box 127 through the exhaust port 1205, and the air is sprayed to the bottom through the air jet hole 128 of the upper air box 127, so that the high-pressure air discharged from the air jet hole 128 will carry the heat from the surface of the ceramic heating tube 129 and spray to the surface of the ozone destruction catalyst 9, so that The impurity particles that have been cleaned and brushed off in the air holes 91 will fall onto the inclined semicircular dust guide plate 61 and enter the dust box 6 from the dust outlet 62, so that the ozone decomposition catalyst 9 is continuously treated at high temperature, so that the ozone decomposition catalyst 9 continues to maintain its activity in ozone decomposition. The gas entering the dust box 6 is filtered by the filter valve 7 and then refluxed through the pipeline to the ozone inlet interface 2 to circulate into the medium and high temperature chamber 11. The impurity particles left in the dust box 6 will be uniformly recovered and processed by the chemical processing personnel at a later stage, completing the sustainable decomposition of chemical pollutants.
