[0002] Waste gas refers to harmful gases discharged by humans during the production and living processes. If the discharged gases are not purified, it will seriously pollute the environment and affect human health, and the organic volatile waste gas is more serious.

[0003] For example, the utility model patent with the application number 202320884846.0 and the name of catalytic combustion equipment for treating organic volatile gases discloses a catalytic combustion equipment for treating organic volatile gases, including a combustion chamber. A rotating rod is rotatably connected to the rear side wall in the combustion chamber through a bearing. A rotating sleeve is movably installed on the rotating rod. A catalytic plate is fixedly connected to the outer side wall of the rotating sleeve. A preheating box is fixedly welded to the top of the combustion chamber, and a heater is fixedly installed at the bottom of the combustion chamber; The utility model rotates the combustion catalyst in the combustion chamber by a driving motor to increase the contact area and time between the combustion catalyst and the organic volatile waste gas, and also preheats the waste gas through the provided preheating box to reduce the heating time of the waste gas, and recovers and utilizes the generated heat during the treatment process;

[0004] The above patent also has the following defects. When treating waste gas, since there is no device to scrape off the dirt adhering to the surface of the catalytic plate during the combustion process of the waste gas, the dirt adhering to the surface of the catalytic plate will gradually increase, eventually causing the air inlet holes on the catalytic plate to be blocked, resulting in the waste gas being unable to fully contact the combustion catalyst, thus reducing the treatment effect of the organic volatile waste gas. In view of this, the present utility model is proposed. Summary of the Utility Model

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model but are not used to limit the scope of the present utility model.

[0021] Embodiment 1:

[0022] Referring to Figure 1 , Figure 2 , Figure 4 , the catalytic combustion gas treatment equipment includes a combustion chamber 1. The bottom side wall of the combustion chamber 1 is fixedly connected and communicated with an air inlet pipe 101, and the top is fixedly connected and communicated with an air outlet pipe 102. It further includes: a rotating shaft 301 rotatably connected in the combustion chamber 1; a plurality of catalytic plates 302, which are circumferentially and equidistantly fixedly connected to the rotating shaft 301. Among them, a storage groove is formed on the catalytic plate 302, and a combustion catalyst is filled in the storage groove. A cover plate 303 for closing the storage groove is detachably connected to the catalytic plate 302; a scraping sleeve 504 is sleeved on the catalytic plate 302 and is in contact with the surface of the catalytic plate 302. Among them, sliding sleeves 502 are fixedly connected to both sides of the scraping sleeve 504, and guide rods 5 are symmetrically fixedly connected to the rotating shaft 301 and are used in cooperation with the sliding sleeves 502. The sliding sleeves 502 are slidably connected to the guide rods 5, and limiting blocks 501 are fixedly connected to the guide rods 5; an elastic member is arranged between the limiting blocks 501 and the sliding sleeves 502; a driving part is arranged on the combustion chamber 1 and is used to drive the rotating shaft 301 to rotate.

[0023] The driving part includes a DC motor 3, which is fixedly installed on the side wall of the combustion chamber 1. The rotating shaft 301 penetrates one end of the combustion chamber 1 and is fixedly connected to the output end of the DC motor 3.

[0024] It also includes electric heating rods 2. There are multiple electric heating rods 2, and the multiple electric heating rods 2 are fixedly connected to the inner wall of the bottom of the combustion chamber 1 at equal intervals.

[0025] The elastic component includes a second spring 503. The second spring 503 is sleeved on the guide rod 5. One end of the second spring 503 is fixedly connected to the sliding sleeve 502, and the other end is fixedly connected to the limiting block 501.

[0026] During use, the organic volatile waste gas is transported into the combustion chamber 1 through the intake pipe 101. Subsequently, the electric heating rods 2 are turned on, and then the organic volatile waste gas is heated. During the heating process of the waste gas, through contact with the combustion catalyst, flameless combustion is carried out;

[0027] At the same time, the DC motor 3 is started. The DC motor 3 drives the rotating shaft 301 to rotate. The rotating shaft 301 drives the catalytic plate 302 to rotate, so that during the rotation of the catalytic plate 302, the organic volatile waste gas can fully contact the combustion catalyst, and then the organic volatile waste gas is fully burned, thereby improving the treatment effect of the organic volatile waste gas. Then, the waste gas after full combustion can be discharged from the combustion chamber 1 through the exhaust pipe 102;

[0028] Since the DC motor 3 is a motor that adjusts the speed by regulating the power supply voltage or current, during the treatment of the organic volatile waste gas, the DC motor 3 can be used to intermittently drive the rotating shaft 301 to rotate rapidly, thereby generating centrifugal force, so that the sliding sleeve 502 moves toward the side close to the limiting block 501 under the action of the centrifugal force and compresses the second spring 503. At the same time, the sliding sleeve 502 drives the scraping sleeve 504 to move synchronously, so that the scraping sleeve 504 moving along the surface of the catalytic plate 302 can scrape off the dirt adhered to the surface of the catalytic plate 302 during the waste gas combustion process, thereby ensuring the smoothness of the air intake holes on the catalytic plate 302 (as shown in Figure 1 、 Figure 2 ), so that the waste gas can fully contact the combustion catalyst and further improve the treatment effect of the organic volatile waste gas;

[0029] When the DC motor 3 drives the rotating shaft 301 to rotate slowly, the centrifugal force generated when the rotating shaft 301 rotates rapidly disappears. Then, the compressed second spring 503 generates a thrust, pushing the sliding sleeve 502 to slide on the guide rod 5 away from the limiting block 501. At the same time, the sliding sleeve 502 drives the scraping sleeve 504 to move synchronously until the scraping sleeve 504 returns to the initial position (as shown in Figure 2As shown in the figure, the scraping sleeve 504 that moves along the surface of the catalytic plate 302 can scrape off the dirt adhering to the surface of the catalytic plate 302 again, improving the cleaning effect of the dirt adhering to the surface of the catalytic plate 302.

[0030] Example 2:

[0031] Refer to Figure 1 、 Figure 3 、 Figure 4 The catalytic combustion gas treatment equipment is basically the same as that in Example 1. Further, connecting blocks 4 are symmetrically and fixedly connected to the catalytic plate 302, connecting grooves for cooperating with the connecting blocks 4 are formed in the cover plate 303, a sliding groove 401 is formed in the connecting block 4, a clamping block 403 is slidably connected in the sliding groove 401, a first spring 402 is arranged in the sliding groove 401, one end of the first spring 402 is fixedly connected to the clamping block 403, and the other end is fixedly connected to the inner wall of the sliding groove 401.

[0032] When the combustion catalyst filled in the storage tank fails and needs to be replaced, first open the door of the combustion box 1 (as Figure 4 shown), then press the clamping block 403 to slide into the sliding groove 401 and compress the first spring 402 until the clamping block 403 completely retracts into the sliding groove 401, so that the limit fixation of the cover plate 303 can be released without the aid of tools. Then remove the cover plate 303 covering the catalytic plate 302, and then quickly open the storage tank, so as to facilitate the staff to replace the combustion catalyst in the storage tank;

[0033] Then fill the new catalyst into the storage tank. After filling, cover the cover plate 303 for closing the storage tank onto the catalytic plate 302. During the covering process, the connecting block 4 is inserted into the connecting groove of the cover plate 303. At this time, the clamping block 403 is retracted into the sliding groove 401 under the extrusion of the groove wall of the connecting groove and compresses the first spring 402. When the cover plate 303 is in contact with the catalytic plate 302, the sliding groove 401 on the connecting block 4 moves out of the connecting groove, and then the compressed first spring 402 generates a thrust, pushing the clamping block 403 to move out of the sliding groove 401 and clamping on the surface of the cover plate 303, thereby limiting and fixing the cover plate 303 covering the catalytic plate 302.

[0034] Example 3:

[0035] Refer to Figure 1, The catalytic combustion gas treatment equipment is basically the same as that in Embodiment 1. Further, solenoid valves are provided on both the intake pipe 101 and the exhaust pipe 102. Through the setting of the solenoid valves, the opening or closing of the intake pipe 101 and the exhaust pipe 102 can be controlled. Therefore, after the organic volatile waste gas enters the combustion chamber 1, the contact time with the combustion catalyst can be extended, so that the organic volatile waste gas can fully contact the combustion catalyst, thereby improving the purification effect of the organic volatile waste gas.
