[0004] The existing technology has the following problems:

[0005] In actual use, existing devices have several drawbacks. Due to the presence of many impurities in the flue gas, some of these impurities adhere to the inner wall of the pipe when it first enters the pipe. After a period of use, these impurities clog the pipe, requiring cleaning and resulting in low efficiency. Furthermore, it is not convenient to recover and utilize excess heat, and the exhaust gas cannot be purified in the second stage, leading to environmental pollution when directly emitted.

[0026] The connecting tube 4 and the inlet tube 81 are interconnected.

[0027] In this design, the movable door 3 can be opened to easily pull out the filter screen 810 inside the track 89 for easy replacement and cleaning.

[0028] like Figures 2-3As shown, the cleaning mechanism 7 includes two sets of fixed frames 71. The upper and lower outer walls of the two sets of fixed frames 71 are fixedly connected to the inner walls of both sides of the connecting pipe 4. A lead screw 72 is rotatably installed inside the two sets of fixed frames 71. A fan 73 is fixedly installed at the top of the lead screw 72. A threaded seat 74 is threaded onto the outside of the lead screw 72. Multiple sets of hanging rods 75 are fixedly connected at equal intervals to the outside of the threaded seat 74. A cleaning ring 76 is fixedly installed at the top of the hanging rod 75. Two sets of connected joints 77 are fixedly installed at the lower end of the connecting pipe 4. A dust collection cylinder 78 is movably installed at the lower end of the joint 77. Multiple sets of brushes 79 are fixedly installed on the outer wall of the cleaning ring 76. Through slots 710 are opened through the front and rear of the fixed frame 71. A threaded section 711 is opened on the inner wall of the joint 77. A threaded section 712 is opened on the outer wall of the top of the dust collection cylinder 78.

[0029] Fan 73 is located inside the protruding tube 5.

[0030] The outer part of the cleaning ring 76 is slidably connected to the inside of the connecting tube 4, and the brush 79 is in contact with the inner wall of the connecting tube 4.

[0031] Threaded connection between thread section 1 711 and thread section 2 712.

[0032] In this design, the through groove 710 facilitates the flow of gas from the connecting pipe 4 to the inlet pipe 81, avoiding obstruction of gas flow. The threaded effect between the first threaded section 711 and the second threaded section 712 facilitates the installation or removal of the dust collection cylinder 78.

[0033] like Figure 4 As shown, the recycling mechanism 8 includes an inlet pipe 81, the bottom end of which is fixedly connected to the inner wall of the lower left end of the box 1. Multiple sets of fixedly installed heaters 82 are distributed at equal intervals on the left end of the inlet pipe 81. A filter 83 is fixedly installed at the upper end of the inlet pipe 81. A storage box 84 is fixedly connected to the middle of the box 1. A sealed copper pipe 85 is fixedly installed through the middle of the storage box 84. A water inlet pipe 86 and a drain pipe 87 are fixedly connected to the left and right sides of the storage box 84, respectively. A partition plate 88 is fixedly connected to the inner wall of the upper end of the box 1. Rails 89 are symmetrically fixedly connected to the inner walls of the top two sides of the box 1. A filter screen 810 is movably installed inside the rails 89.

[0034] The top of the inlet tube 81 passes through the interior of the sealed copper tube 85 and the partition plate 88, and the inlet tube 81 is connected to the space above the partition plate 88.

[0036] In this design, water can be easily added to the storage tank 84 via the inlet pipe 86, while the drain pipe 87 facilitates the discharge of heated water. The rubber sealing gaskets installed at the top and bottom of the sealing copper pipe 85 can improve the sealing performance of the storage tank 84. By passing the top of the inlet pipe 81 through the sealing copper pipe 85, the high-temperature gas passing through the inlet pipe 81 can be used to heat the water flow in the storage tank 84.

[0037] The working principle of this waste gas treatment ultra-clean furnace will be explained in detail below.

[0038] like Figures 1-4 As shown, in use, the ultra-clean waste gas treatment furnace allows gas to be easily fed into the convex pipe 5 and connecting pipe 4 via the inlet pipe 6. The gas is then discharged into the inlet pipe 81 inside the housing 1, where it is heated and burned by the heater 82 at the outer end of the inlet pipe 81. The waste gas is then filtered once by the filter 83. The high-temperature waste gas is then discharged into the top of the housing 1. Simultaneously, the water in the storage tank 84 is heated by the high-temperature waste gas, and the heated water can be used for production or domestic purposes. Finally, the fan 9 is activated to extract the waste gas from the top of the housing 1, allowing it to undergo secondary filtration through two sets of filter screens 810 before being discharged. The exhaust gas is discharged through pipe 10, ensuring that the exhaust gas is clean and avoiding environmental pollution. At the same time, when the gas enters the convex pipe 5, it blows the fan 73 to drive the screw 72 to rotate. When the screw 72 rotates, it drives the threaded seat 74 of the threaded connection to move horizontally left and right. The threaded seat 74 can drive the cleaning slip ring to slide left and right synchronously through the hanger 75. When the cleaning ring 76 slides, the brush 79 will clean the impurities adsorbed on the inner wall of the connecting pipe 4. Finally, the impurities cleaned by the brush 79 will be pushed into the connector 77 by the cleaning ring 76 and enter the dust collection cylinder 78 through the connector 77. By unscrewing the dust collection cylinder 78, the impurities in the dust collection cylinder 78 can be treated.

[0039] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
