The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0038] The embodiments of this utility model will be described below based on its overall structure.

[0039] Example 1:

[0040] A catalytic combustion device for industrial waste gas treatment, such as Figures 1-6 As shown, the device includes a housing 1, with a filter chamber 18 on one side of the housing 1 and a slot 3 on the upper side of one side of the housing 1. The filter chamber 18 contains a screen cleaning assembly 9. A combustion chamber 2 is installed on the top of the housing 1. An air inlet pipe 8 and an air pipe 10 are connected to the top of the combustion chamber 2. Exhaust gas can enter the interior of the combustion chamber 2 through the air inlet pipe 8, while air can enter the interior of the combustion chamber 2 through the air pipe 10. A heating rack 5 is located in the middle of the interior of the combustion chamber 2. Electric heaters 7 are installed on both sides of the interior of the combustion chamber 2. A pressure detector 6 is installed on one side of the interior of the combustion chamber 2. The electric heaters 7 can heat the interior of the combustion chamber 2, while the pressure detector 6 can detect the pressure inside the combustion chamber 2.

[0041] See Figures 1-5An air pump 16 is installed at the lower interior of the housing 1. The outlet of the air pump 16 is connected to an air supply pipe 17 extending into the filter chamber 18. When it is necessary to extract the exhaust gas after combustion, the operator can start the air pump 16. The air pump 16 can extract the exhaust gas. The filter chamber 18 is equipped with a filter screen 19 and an activated carbon layer 20. An exhaust pipe 21 is installed on the other side of the housing 1 and is connected to the filter chamber 18. The filter screen 19 can filter the exhaust gas, while the activated carbon layer 20 can adsorb and purify the exhaust gas. A sealing door 23 is installed on one side of the outer surface of the housing 1 through a hinge, and a sealing gasket is provided on the back of the sealing door 23 to improve the sealing of the filter chamber 18. A second temperature sensor 24 is installed at the upper interior of the combustion chamber 2. A control panel 22 is also installed on the outer surface of the housing 1. The control panel 22 is electrically connected to the air pump 16, the second temperature sensor 24, the solenoid valve 14, the heating frame 5, the electric heater 7, the air pressure detector 6, and the first temperature sensor 12.

[0042] Specifically, the screen cleaning assembly 9 includes a rotating shaft 901 installed in the filter chamber 18 via a sealed bearing and a bearing seat 911 installed on one side inside the slot 3. The interior of the bearing seat 911 is connected to a movable shaft 908 via a bearing, and a rotating ring 907 is installed at one end of the movable shaft 908. A driven bevel gear 909 is installed on the outer wall of the movable shaft 908. A rotating plate 906 is connected to one side of the rotating ring 907 via a rotating shaft, and a movable rod 905 is rotatably connected to the bottom of the rotating plate 906 via a rotating shaft.

[0043] Specifically, the bottom end of the movable rod 905 extends into the interior of the filter chamber 18 and is bolted to a scraper 903. A fan blade 902 is mounted on one end of the rotating shaft 901 located inside the filter chamber 18, and a drive bevel gear 910 is mounted on the other end of the rotating shaft 901 located inside the slot 3. When exhaust gas enters the filter chamber 18 through the gas supply pipe 17, the fan blade 902 will rotate due to the continuous impact of the exhaust gas, thereby driving the rotating shaft 901 to rotate, which in turn drives the drive bevel gear 910 to rotate. The drive bevel gear 910 meshes with the driven bevel gear 909. The diameter of the drive bevel gear 910 is smaller than the diameter of the driven bevel gear 909 so that when the drive bevel gear 910 rotates, it can drive the driven bevel gear 909 to rotate, thereby driving the movable shaft 908 to rotate. One side of the scraper 903 is in contact with the filter screen 19, and the length of the scraper 903 is the same as the length of the filter screen 19 so that when the scraper 903 moves, it can clean the dust or impurities attached to the filter screen 19.

[0044] Example 2:

[0045] Based on the above embodiment 1, in order to prevent the rotating ring 907 from rotating arbitrarily, it is necessary to limit the rotating ring 907, so the following structure will be set.

[0046] Specifically, the cleaning assembly 9 also includes multiple pin holes 913 formed on the outer wall of the rotating ring 907 and a through hole 914 formed on one side of the top of the housing 1. A pin 912 is inserted into the through hole 914. The bottom end of the pin 912 is inserted into the inside of a pin hole 913, and the diameter of the top end of the pin 912 is larger than the diameter of the through hole 914. When the pin 912 is inserted into the inside of a pin hole 913, it can limit the rotating ring 907 and prevent the rotating ring 907 from rotating at will.

[0047] Example 3:

[0048] Based on the above embodiment one, since the temperature of the exhaust gas is high after combustion treatment, the following structure will be set up in order to recover and utilize the waste heat of the exhaust gas.

[0049] See Figures 1-5 The shell 1 also has a heat exchange chamber 4 inside, and a heat exchange tube 13 is installed inside the heat exchange tube 13. A solenoid valve 14 is installed on the heat exchange tube 13, and the top end of the heat exchange tube 13 extends into the interior of the combustion chamber 2. When the high-temperature exhaust gas enters the interior of the heat exchange tube 13, it can heat the water inside the heat exchange chamber 4 so as to recover and utilize the waste heat of the exhaust gas. A first temperature sensor 12 is installed on one side inside the heat exchange chamber 4. A drain valve 15 extending into the heat exchange chamber 4 is installed on the lower side of one side of the shell 1. A water injection pipe 11 extending into the heat exchange chamber 4 is installed on the upper side of one side of the shell 1, and a cap is threaded to the top end of the water injection pipe 11. When it is necessary to drain the heated water inside the heat exchange chamber 4, the drain valve 15 can be opened so that the hot water can be discharged through the drain valve 15. The air outlet end of the heat exchange tube 13 is connected to the air inlet end of the air pump 16 so that the exhaust gas can enter the interior of the heat exchange tube 13.

[0050] Example 4:

[0051] Based on the above embodiment 1, in order to prevent exhaust gas from entering the slot 3 through the gap between the movable rod 905 and the filter chamber 18, the following structure will be set to improve the sealing between the movable rod 905 and the filter chamber 18.

[0052] See Figure 3 , Figure 4 and Figure 6 The cleaning assembly 9 also includes a sealing ring 904 installed above the inside of the filter chamber 18. The outer wall of the movable rod 905 fits against the inner wall of the sealing ring 904. The sealing ring 904 can improve the sealing between the movable rod 905 and the filter chamber 18, preventing unfiltered exhaust gas from entering the slot 3.

[0053] The working principle of this utility model is as follows: First, when using it, connect the power supply, then open the cover and add cold water into the heat exchange chamber 4 through the water injection pipe 11. After adding, screw the cover back onto the water injection pipe 11. When the industrial waste gas is burned, the waste gas can enter the combustion chamber 2 through the air inlet pipe 8, while the air enters the combustion chamber 2 through the air pipe 10. Then, start the heating frame 5 and the electric heater 7 to heat the waste gas and make the industrial waste gas burn completely at high temperature. After complete combustion, start the air pump 16 and the solenoid valve 14. After the solenoid valve 14 is opened, the waste gas can enter the heat exchange tube 13 to heat the cold water. The waste gas enters the filter chamber 18 through the air supply pipe 17. After being filtered and purified by the filter screen 19 and the activated carbon layer 20, it is discharged through the exhaust pipe 21.

[0054] When it is necessary to scrape and clean the dust or impurities attached to the filter screen 19, the operator can remove the pin 912 from the pin hole 913 so that the rotating ring 907 is no longer limited. When the exhaust gas enters the filter chamber 18 through the air supply pipe 17, the fan blade 902 will rotate due to the continuous impact of the exhaust gas, which will drive the rotating shaft 901 to rotate, then drive the driving bevel gear 910 to rotate, then drive the driven bevel gear 909 to rotate, and drive the movable shaft 908 to rotate, which in turn drives the rotating ring 907 to rotate. The rotating ring 907 then drives the rotating plate 906 to rotate. This causes the movable rod 905 to move, which in turn moves the scraper 903. As the scraper 903 moves, it can clean the dust or impurities attached to the filter screen 19. As the rotating ring 907 continues to rotate, the movable rod 905 will move up and down repeatedly, which in turn moves the scraper 903 up and down repeatedly, thereby improving the cleaning efficiency of the filter screen 19. When the filter screen 19 does not need to be cleaned, the operator can insert the pin 912 into the corresponding pin hole 913 to limit the rotating ring 907. At this time, the rotating ring 907 cannot rotate, thus preventing the scraper 903 from moving up and down continuously.

[0055] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
