[0002] Currently, when treating waste gas through catalytic combustion, there is no mechanical filtration of particulate matter in the organic waste gas before catalytic combustion. This causes particulate matter to clog the pipes during catalytic combustion, affecting the efficiency of catalytic combustion. Utility Model Content

[0004] To achieve the above objectives, this application adopts the following technical solution:

An opening for the filter membrane to extend is provided on the side wall of the protective shell, and the outer wall corresponding to the opening... A scraper plate is fixedly connected to the outside of the filter membrane. A rotating mechanism for driving two take-up rollers to rotate is fixedly connected to the outer wall of the purification shell. A through hole is also opened on the side wall of the purification shell, and an air inlet pipe is rotatably sleeved in the corresponding through hole through a bearing. The end of the air inlet pipe away from the purification shell is rotatably connected to an air supply pipe through a rotary sealing joint. The end of the air inlet pipe inside the purification shell is fixedly connected to an air jet pipe. A drive mechanism for driving the air inlet pipe to rotate is fixedly connected to the outside of the purification shell. An insert cylinder is integrally connected to the bottom of the purification shell. A dust collection box that is inserted and sleeved outside the insert cylinder is also fixedly snapped into the lower end of the purification shell.

[0006] Preferably, the rotating mechanism includes two horizontal plates symmetrically fixedly connected to the outside of the purification shell, a worm gear rotatably connected between the two horizontal plates, one end of the rotating shaft extending through and out of the purification shell and fixedly connected to a worm wheel meshing with the worm gear, a rotary motor fixedly connected to the lower end of the lower horizontal plate, and the upper output shaft of the rotary motor fixedly connected to the lower end of the worm gear.

[0007] Preferably, the drive mechanism includes a drive motor fixedly connected to the outside of the purification shell, a drive gear fixedly connected to the output end of the drive motor, and a driven gear meshing with the drive gear fixedly sleeved on the wall of the air intake pipe.

[0008] Preferably, the top of the inner wall of the purification shell corresponding to the plug-in cylinder is formed with a conical expansion structure.

[0009] Preferably, two positioning plates are symmetrically fixedly connected to the lower end of the purification shell, and an L-shaped support plate that is fixedly connected to the lower end of the positioning plate and supports the lower side of the ash collection box.

[0010] Preferably, a T-shaped locking block is fixedly connected to the upper end of the positioning plate, and a T-shaped locking groove is provided on the lower side wall of the purification shell to match and engage with the T-shaped locking block.

[0011] Preferably, the surface of the positioning plate is provided with multiple insertion holes, and the corresponding movable sleeves in the insertion holes are provided with limit rods. The lower end of the purification shell is provided with multiple limit grooves that match and insert with the limit rods. The lower ends of the multiple limit rods are fixedly connected to the same limit pull plate.

[0012] Preferably, a shock-absorbing rubber pad is fixedly connected to the lower end of the base.

[0013] Preferably, the jet pipe has multiple diffuser shrouds uniformly and fixedly connected to its wall.

[0014] Compared with the prior art, this application provides a high-efficiency catalytic combustion device for organic waste gas, which has the following beneficial effects:

[0015] 1. The system consists of a purification shell and a catalytic combustion chamber, connected by a ventilation pipe. Before the organic waste gas undergoes catalytic combustion, the waste gas is introduced into the purification shell through a gas supply pipe, an inlet pipe, and a jet pipe. The filter membrane and filter screen effectively filter and intercept impurities in the organic waste gas. During filtration, a rotary motor and a drive motor are activated. The rotary motor drives a worm gear, which, through meshing with a worm wheel, drives two rotating shafts to rotate synchronously, thereby driving two winding rollers. This allows the filter membrane to be wound up and down repeatedly. During this process, a scraper removes the impurities adhering to the surface of the filter membrane, which then falls into the ash collection box through a connecting tube. This ensures the stable filtration performance of the filter membrane, guaranteeing the quality and efficiency of organic waste gas treatment. The drive motor drives a drive gear, which, through meshing with a driven gear, rotates the inlet pipe, which in turn rotates the jet pipe. This ensures that the supplied waste gas is evenly distributed on the filter membrane and filter screen, improving their utilization rate and guaranteeing filtration quality.

[0016] 2. With the provided ash collection box, after the ash collection box is installed at the lower end of the purification shell, the positioning plate drives the L-shaped support plate to quickly connect to the lower end of the purification shell through the matching and locking of the T-shaped block and T-shaped slot. This allows the L-shaped support plate to support the lower side of the ash collection box, achieving a stable support for the ash collection box. At this time, the limiting rod is aligned with the limiting groove, and the limiting spring pulls up the limiting pull plate. The limiting pull plate pushes the limiting rod into the limiting groove, thus achieving a stable limit on the positioning plate. This ensures the installation stability of the ash collection box and allows for quick assembly and disassembly for easy use.

[0017] Moreover, the parts of the device not involved are the same as or can be implemented using existing technologies. This application can effectively filter and intercept impurity particles in organic waste gas, ensuring the quality of subsequent catalytic combustion reaction, and can ensure continuous and stable filtration performance, resulting in high quality of use.

[0032] The operating principle of this utility model is described as follows:

[0033] In use, this device consists of a purification shell 3 and a catalytic combustion chamber 4, connected by a vent pipe 5. Before the organic waste gas undergoes catalytic combustion, the waste gas is introduced into the purification shell 3 through a gas supply pipe 13, an inlet pipe 12, and a jet pipe 14. The filter membrane 10 and filter screen 6 effectively filter and intercept impurities in the organic waste gas. During filtration, a rotary motor 20 and a drive motor 21 are activated. The rotary motor 20 drives the worm gear 18 to rotate, and the meshing of the worm gear 18 and worm wheel 19 drives the two rotating shafts 8 to rotate synchronously, thereby driving the two take-up rollers 9. This allows the filter membrane 10 to be retracted and extended. During this process, the filter membrane 10 has its surface-attached impurities scraped off by a scraper plate 11 and falls into the dust collection box 16 through a connector 15. This ensures the stable filtration performance of the filter membrane 10, guaranteeing the quality and efficiency of organic waste gas treatment. The drive motor 21... The drive gear 22 rotates, and the meshing action of the drive gear 22 and driven gear 23 drives the intake pipe 12 to rotate, which in turn drives the jet pipe 14 to rotate. This ensures that the incoming exhaust gas acts evenly on the filter membrane 10 and the filter screen 6, improving the utilization rate of the filter membrane 10 and the filter screen 6 and ensuring the filtration quality. The dust collection box 16 is installed at the lower end of the purification shell 3 and is positioned by the matching engagement of the T-shaped locking block 26 and the T-shaped locking groove 27. Plate 24 drives L-shaped support plate 25 to quickly connect to the lower end of the purification shell 3, thereby allowing L-shaped support plate 25 to support the lower side of ash collection box 16, achieving a stable support for ash collection box 16. At this time, the limiting rod 28 is aligned with the limiting groove 29, and the limiting spring 31 pulls up the limiting pull plate 30. The limiting pull plate 30 pushes the limiting rod 28 into the limiting groove 29, thereby achieving a stable limit on the positioning plate 24, ensuring the installation stability of ash collection box 16, and enabling quick disassembly and assembly for easy use.
