Waste gas passes through the waste gas inlet, sequentially through the gas conveying device and the gas flow control device, and enters the microwave catalytic device to be purified into clean gas before being discharged. The gas conveying device has one or at least two gas outlets. This utility model provides a waste gas purification device based on microwave catalysis that can precisely control waste gas treatment, is easy to maintain, has a long service life, achieves multi-channel waste gas purification, provides controllable operation, can greatly improve the waste gas purification rate, and has strong environmental adaptability.

[0004] Problems with existing technologies: Some existing microwave catalytic oxidation waste gas purification equipment cannot adjust the amount of waste gas added during use, and the dust in the waste gas can easily clog the filter device, requiring frequent shutdowns for unclogging, which affects the waste gas treatment efficiency.

[0005] Therefore, there is an urgent need for a microwave catalytic oxidation waste gas purification device. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a microwave catalytic oxidation waste gas purification device.

The filter mechanism includes a partition plate, which is fixed to the inner wall of the air inlet pipe by bolts. A strip-shaped hole A is provided on one side of the partition plate, and a strip-shaped hole B is provided on one side of the strip-shaped hole A. A servo motor is fixedly installed in the middle of the partition plate, and multiple baffles are fixedly installed on the rotating end of the servo motor.

The length of the strip hole A is twice that of the strip hole B, thus enabling the microwave catalytic oxidation waste gas purification equipment to accept air with two different hole diameters. Under the baffle effect, the amount of waste gas added can be adjusted in various ways during use. Multiple inclined plates block the waste gas, and the inclined plates drive the rotating shaft to rotate, which in turn drives brush plate A and brush plate B to brush both sides of the filter plate synchronously. This prevents dust in the waste gas from clogging the filter device, avoids frequent shutdowns for unclogging, and improves the waste gas treatment efficiency.

[0016] 2. By pulling the baffle with the handle, the filter plate can be quickly disassembled through the cooperation of the insertion groove and the sealing ring, which improves the convenience of maintenance of the microwave catalytic oxidation waste gas purification equipment.

[0030] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0031] Example 1: As Figure 1-5As shown, a microwave catalytic oxidation waste gas purification device includes a water inlet pipe, a filter box 200 installed at one end of the air inlet pipe 100, a catalytic tube 300 installed at one end of the filter box 200, and a filtration mechanism disposed inside the air inlet pipe 100 for filtering waste gas. Magnet plates 400 are bolted to both sides of the air inlet pipe 100, and the magnet plates 400 magnetically adsorb iron dust in the waste gas. The filtration mechanism includes a partition plate 101, which is bolted to the inner wall of the air inlet pipe 100. A strip-shaped hole A102 is cut on one side of the partition plate 101. A strip-shaped hole B103 is cut on one side of 02. The length of the strip-shaped hole A102 is twice that of the strip-shaped hole B103, thus allowing the microwave catalytic oxidation waste gas purification equipment to accept air intake with two different hole diameters. A servo motor 104 is bolted to the middle position of the partition 101. Multiple baffles 105 are bolted to the rotating end of the servo motor 104. The servo motor 104 drives the baffles 105 to rotate. A crossbeam 201 is welded to the middle position of the filter box 200. A rotating shaft 202 is rotatably connected to the middle position of the crossbeam 201. Multiple inclined plates 203 are welded to the outer side of the rotating shaft 202. An inclined plate 203 blocks the exhaust gas, thereby driving the rotating shaft 202 to rotate. Brush plates A204 are bolted to both ends of the rotating shaft 202. The rotating shaft 202 drives the brush plates A204 to rotate, brushing the filter plate 402. A transmission mechanism is provided at one end of the rotating shaft 202 for driving the microwave catalytic oxidation exhaust gas purification equipment. The transmission mechanism includes a housing 301, which is bolted to one end of the rotating shaft 202. A square plate 303 is slidably connected to the inner wall of the housing 301.

The angle between the brush plate A204 and the brush plate B304 is 180°. The connecting rod 302 drives the brush plate B304 to rotate, so as to realize the synchronous brushing of both sides of the filter plate 402. An electromagnet ring 500 is fixed to the inner wall of the catalytic tube 300 by bolts. The electromagnet ring 500 generates a high-frequency electromagnetic field to perform microwave catalysis on the waste gas. One end of the catalytic tube 300 is threadedly connected to an activated carbon canister 600, which filters the waste gas again.

[0032] In this embodiment, the servo motor 104 drives the shielding strip 105 to rotate. The length of the strip hole A102 is twice that of the strip hole B103, thus enabling the microwave catalytic oxidation waste gas purification equipment to accept air with two different apertures. Under the shielding effect of the shielding strip 105, the amount of waste gas added to the microwave catalytic oxidation waste gas purification equipment can be adjusted in various ways during use. Multiple inclined plates 203 shield the waste gas, and the inclined plates 203 drive the rotating shaft 202 to rotate, which in turn drives the brush plates A204 and B304 to brush both sides of the filter plate 402 synchronously, preventing dust in the waste gas from clogging the filter device, avoiding frequent shutdowns for unclogging, and improving the waste gas treatment efficiency.

A sealing ring 410 is bolted to the outer side of the filter plate 402 to prevent waste gas leakage. A baffle 403 is bolted to the top of the filter plate 402, and a handle 404 is bolted to the top of the baffle 403, allowing the baffle 403 to move by pulling the handle 404. A track 110 is bolted to the bottom of the filter box 200, and a collection box 120 is slidably connected to the inner wall of the track 110 to collect dust from the waste gas.

[0034] In this embodiment, by pulling the baffle 403 with the handle 404, the filter plate 402 can be quickly disassembled under the cooperation of the insertion groove 401 and the sealing ring 410, which improves the convenience of maintenance of the microwave catalytic oxidation waste gas purification equipment.
