Description

Technical Field

[0001] The utility model relates to the technical field of waste gas purification, in particular to a zeolite wheel CO environmentally friendly waste gas purification device. Background Art

[0002] The zeolite rotor concentrates high-volume, low-concentration exhaust gas into high-concentration, low-volume exhaust gas, thereby reducing equipment investment and operating costs and improving exhaust gas treatment efficiency. When treating high-volume, low-concentration exhaust gas for combustion and recovery, if direct combustion is performed without a zeolite rotor, the exhaust gas treatment equipment would be not only bulky but also incur significant operating costs. The zeolite rotor is equipped with an adsorption zone: the zeolite rotor rotates continuously at a speed of 1-6 revolutions per hour, simultaneously transferring adsorbed volatile organic compounds (VOCs) to the desorption zone. In the desorption zone, VOCs are desorbed using a small stream of heated gas (180-220°C). Cooling and regeneration: After desorption, the zeolite rotor rotates to the cooling zone, where it cools and then returns to the desorption zone, where it continues to adsorb VOCs. The zeolite rotor CO2 environmental waste gas purification system can be divided into an equipment treatment zone, a material regeneration zone, and an equipment cooling zone. Centralized channel equipment operates sequentially in each zone. After passing through the pre-filter, the organic waste gas passes through the treatment area of ​​the concentration channel equipment. In the treatment area, the waste gas is adsorbed and removed by the adsorbent, and the purified air is discharged from the treatment area of ​​the concentration tank.

[0003] After searching, the Chinese patent publication number CN218901348U discloses a zeolite rotor CO environmentally friendly waste gas purification device, including a main purifier and a filtering mechanism. A desorption mechanism for desorbing exhaust gas is provided in the upper middle part of the main purifier, and the filtering mechanism for filtering and removing impurities is provided in the middle part of the front end of the desorption mechanism, and a rotating mechanism for rotational lubrication is provided at the lower part of the desorption mechanism.

[0004] In the above scheme, the filter element is mainly used to perform preliminary filtration of the exhaust gas. However, some dust in the organic exhaust gas that is not filtered and intercepted will adhere to or adsorb on the inner wall of the air inlet. Under long-term working conditions, a large amount of deposits will be generated on the inner wall, increasing the cleaning burden of workers. In addition, the dust will also clog the filter holes on the air inlet end face of the filter element, affecting the efficiency of subsequent exhaust gas purification. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that a large amount of deposits are easily generated on the inner wall of the air inlet and dust can also block the filter holes on the air inlet end face of the filter element, and to propose a zeolite wheel CO environmentally friendly exhaust gas purification device.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0009] In order to improve the stability of the filter element frame, further, the transmission gears are symmetrically arranged in two groups, and the two groups of transmission gears rotate in the same direction.

[0010] In order to facilitate the movement of the cleaning strip, preferably, a magnetic block is fixedly connected to the air inlet channel, and a contact block is provided at the end of the cleaning strip, and the contact block is magnetically matched with the magnetic block.

[0011] In order to facilitate the rotation of the annular frame, preferably, a convex tooth is fixedly connected to the outer wall of the annular frame, and an auxiliary gear is rotatably connected to the air intake channel. The auxiliary gear is engaged with the convex tooth, and the auxiliary gear is fixedly connected to the end of the transmission gear through a connecting shaft.

[0012] In order to facilitate the purification of the organic waste gas in the purifier, preferably, a rotor box is provided on the output end of the filter box, and a desorption fan is provided in the rear middle part of the rotor box.

[0013] Compared with the existing technology, the utility model provides a zeolite rotor CO environmentally friendly waste gas purification device with the following beneficial effects:

[0014] 1. This zeolite rotor CO2 environmentally friendly exhaust gas purification device fits the cleaning brush against the outer wall of the filter element in the filter element frame. As the filter element frame rotates, the cleaning strip contacts the outer wall of the filter element, thereby performing real-time contact cleaning of the filter holes on the air inlet end face of the filter element frame, thereby improving the efficiency of subsequent exhaust gas purification and reducing the clogging of the filter holes by dust.

[0015] 2. The zeolite rotor CO2 environmentally friendly exhaust gas purification device will generate fluctuations when the dial plate returns to its original position. At this time, the dust on the inner wall of the air intake channel will be cleaned or scraped off by the fluctuation, thereby cleaning the dust adhered or adsorbed on the inner wall of the air intake channel, reducing the accumulation on the inner wall of the air intake channel due to long-term working conditions and reducing the cleaning burden on workers.

[0016] The parts not involved in this device are the same as the existing technology or can be implemented by using the existing technology. On the one hand, the utility model can use the cleaning strip to contact the outer wall of the filter element, which will perform real-time contact cleaning of the filter holes on the air inlet end face of the filter element frame, thereby improving the efficiency of subsequent exhaust gas purification and reducing the blockage of the filter holes by dust. On the other hand, it can also clean or wave-scrape the dust on the inner wall of the air intake channel, and then clean the dust adhered or adsorbed on the inner wall of the air intake channel, reducing the accumulation on the inner wall of the air intake channel due to long-term working conditions, and reducing the cleaning burden of workers.

[0025] Example:

[0026] Reference Figure 1-Figure 5 A zeolite rotor CO environmentally friendly waste gas purification device includes a purifier, a filter box 2 is provided at the air inlet end of the purifier, and a rotor box 6 is also provided on the output end of the filter box 2. The interior is zeolite, which concentrates large-volume, low-concentration organic waste gas into high-concentration, small-volume waste gas. A desorption fan is provided in the middle of the rear of the rotor box 6 for transporting the gas. This is the existing technology and will not be described in detail.

[0027] In addition, a circular filter element frame 3 is provided in the filter box 2, and the filter element frame 3 can be disassembled to the outside for cleaning. A driving part for driving the filter element frame 3 to rotate is provided under the filter box 2, and the driving part includes a transmission gear 4 rotatably connected to the filter box 2, and a convex tooth is provided on the outside of the filter element frame 3, which meshes with the transmission gear 4, and the transmission gear 4 is symmetrically provided in two groups, and the two groups of transmission gears 4 have the same rotation direction. A driving machine such as a pneumatic motor or a hydraulic motor can be used to provide a high torque output to rotate the filter element frame 3, and the rotation speed of the filter element frame 3 is controlled by the rotation speed of the driving machine.

[0028] In addition, a cleaning strip 7 is provided on the inner wall of the filter box 2, and a cleaning brush is provided on the cleaning strip 7. The working end of the cleaning strip 7 is then fitted against the outer wall of the filter element frame 3, and the cleaning brush is fitted against the outer wall of the filter element in the filter element frame 3. When the filter element frame 3 rotates, the cleaning strip 7 will contact the outer wall of the filter element, and the filter holes on the air inlet end face of the filter element frame 3 will be cleaned in real time by contact, thereby improving the efficiency of subsequent exhaust gas purification and reducing the blockage of the filter holes by dust.

[0029] Please refer to Figure 3 and Figure 4As shown in, an air intake channel 1 is provided at the air intake end of the filter box 2, a slide groove is opened on the inner wall of the air intake channel 1, and an annular frame 5 is rotatably connected to the slide groove, and a paddle 102 is connected to the annular frame 5 through a flexible connector, and the flexible connector can be a spring or rubber made of high-temperature resistant material, and a convex tooth is fixedly connected to the outer wall of the annular frame 5, and the convex tooth is arranged inside the slide groove, and an auxiliary gear 401 is also rotatably connected to the air intake channel 1, and the auxiliary gear 401 is then meshed with the convex tooth on the outer wall of the annular frame 5, and then the auxiliary gear 401 is fixedly connected to the end of the transmission gear 4 through a connecting shaft so that it can rotate synchronously, and a magnetic block 101 is fixedly connected in the air intake channel 1, and a contact block is provided at the end of the cleaning strip 7. The material of the contact block is a material that is attracted to the magnetic block 101, such as iron, nickel and steel, and the contact block can magnetically cooperate with the magnetic block 101.

[0030] Here, when the transmission gear 4 drives the filter element frame 3 in the filter box 2 to rotate, the auxiliary gear 401 rotates synchronously, thereby causing the annular frame 5 to rotate in a circle in the slide groove. At this time, the dial plate 102 will move synchronously. During the movement, the contact block at the end can contact and be adsorbed with the magnetic block 101. At this time, the dial plate 102 is offset, and the spring or rubber made of high-temperature resistant material will elastically deform to compensate for the displacement of the dial plate 102. When the contact block gradually moves away from the magnetic range of the magnetic block 101, the dial plate 102 will fluctuate while returning to its position. At this time, the dust on the inner wall of the air intake channel 1 will be cleaned or scraped off by fluctuations, and the dust adhered to or adsorbed on the inner wall of the air intake channel 1 can be cleaned, reducing the accumulation on the inner wall of the air intake channel 1 due to long-term working conditions, and reducing the cleaning burden of workers.
