[0025] Specifically, the heat exchange purification device 5 further includes thermal insulation cotton 54 , and the side wall of the connection box 51 is filled with thermal insulation cotton 54 .

[0026] By adopting the above technical solution, the device can prevent the heat in the exhaust gas from being lost from the connection box 51 through the insulation cotton 54, thereby better meeting the needs of waste heat utilization and ensuring the normal operation.

[0027] Specifically, the purification component 55 includes a threaded block 551, a connecting tube 552, a fixed net 553, activated carbon 554 and an upper tube body 56.

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that the filtering treatment device 6 includes a connecting box 61 and a filter cloth 62 , the inlet pipe 8 and the input pipe 7 are connected via the connecting box 61 , and the filter cloth 62 is installed inside the connecting box 61 .

[0032] By adopting the above technical solution, the device can filter the exhaust gas to a certain extent through the cooperation of structures such as the filter cloth 62 and the connecting box 61, thereby reducing the possibility of excessive impurities entering the device and causing blockage and damage.

[0033] Specifically, the filtering treatment device 6 further includes a transparent window 63 and a blocking block 64 . The blocking block 64 is screw-threadedly mounted on the top of the connection box 61 , and the transparent window 63 is mounted on the inner side of the blocking block 64 .

[0034] By adopting the above technical solution, the staff can unscrew the blocking block 64 to clean the inside of the connection box 61 when necessary, and the staff can observe the situation inside the connection box 61 through the transparent window 63.

[0035] When this embodiment is used, during operation, the chemical exhaust gas passing through the input pipe 7 will enter the connection box 61 in the filtering treatment device 6, and the filter cloth 62 will filter the exhaust gas, and then the exhaust gas will enter the inlet pipe 8, thereby reducing the possibility of excessive impurities entering the device and causing blockage and damage. The staff can unscrew the blocking block 64 to clean the inside of the connection box 61 when necessary, and the staff can observe the situation inside the connection box 61 through the transparent window 63.

[0036] The structure and principle of the support assembly 1 composed of the lower plate and the bracket in the present invention, the combustion catalytic assembly 2 composed of the box body, the burner, the gas box, the through hole, the heating net, the fixed frame, the support rod, the catalytic reactor and the end cover, the gas transmission assembly 3 composed of the row pipe, the support rod, the fixed sleeve and the connecting pipe, the outlet pipe assembly 4 composed of the outlet pipe and the heat exchanger, and the inlet pipe 8 have been disclosed in a chemical exhaust gas catalytic incineration device disclosed in Chinese patent application No. 202121882380.8. Its working principle is that when in use, the burner is started, and the flame ejected from the burner nozzle can heat the heating net, and at the same time, the temperature of the catalytic reactor and the heat exchanger can be increased. After the chemical exhaust gas enters the inlet pipe, it passes through the heat exchanger, the row pipe, the fixed frame, the support rod, the fixed sleeve and the connecting pipe in turn. The sleeve and the connecting pipe enter the gas box, and the chemical exhaust gas can be preheated after passing through the heat exchanger. The preheated chemical exhaust gas enters the gas box and is evenly discharged into the box through the through hole. The chemical exhaust gas entering the box is evenly heated again after passing through the heating net. Then the chemical exhaust gas contacts the catalytic reactor, and the combustible substances in the chemical exhaust gas are oxidized and decomposed and then discharged through the outlet pipe. The chemical exhaust gas after the combustible substances are oxidized and decomposed can heat the heat exchanger when passing through the outlet pipe, so that the heat exchanger can continuously preheat the chemical exhaust gas flowing through it; when the catalytic reactor needs to be replaced, the end cover and the upper end of the box are disassembled, and then the end cover, outlet pipe, discharge pipe and inlet pipe are rotated. When the end cover and the box are staggered, the catalytic reactor can be replaced.

[0037] The working principle and use process of the present invention are as follows: when the catalytic combustion device is needed, the chemical tail gas is sent into the outlet pipe assembly 4 through the input pipe 7 and the inlet pipe 8, and then the chemical tail gas passes through the gas transmission assembly 3 and enters the combustion catalytic assembly 2 on the support assembly 1 for treatment. The treated chemical tail gas passes through the outlet pipe assembly 4 and enters the heat exchange copper cylinder 52 in the heat exchange purification device 5. The staff can send the heat exchange medium into the connecting box 51 through the upper pipe body 56, and then the heat in the chemical tail gas is transferred to the heat exchange medium through the heat exchange copper cylinder 52, and then the heat exchange medium is discharged from the lower pipe body 53 with the heat, so as to utilize the residual heat in the tail gas, and then the tail gas enters the connecting cylinder 552 in the purification assembly 55, and the two fixed nets 5 The activated carbon 554 between 53 purifies the exhaust gas, and the purified exhaust gas is discharged from the connecting tube 552 for use. The staff can unscrew the threaded block 551 to replace the activated carbon 554 when necessary, and the thermal insulation cotton 54 plays a role in reducing heat loss; in the working process, the chemical exhaust gas passing through the input pipe 7 will enter the connecting box 61 in the filtering treatment device 6, and the filter cloth 62 filters the exhaust gas, and then the exhaust gas enters the inlet pipe 8, thereby reducing the possibility of excessive impurities entering the device and causing blockage and damage. The staff can unscrew the blocking block 64 to clean the inside of the connecting box 61 when needed, and the staff can observe the situation inside the connecting box 61 through the transparent window 63.
