Description

Technical Field

[0001] The present application relates to the technical field of waste gas treatment transmission and pressurization, and in particular to a transmission and pressurization device for waste gas treatment. Background Art

[0002] In the waste gas treatment system, the waste gas needs to be transmitted to the treatment equipment (such as filters, absorption towers, etc.) for treatment. During the transmission process, high-pressure fans and pipelines are required. The waste gas is pressurized by using a special high-pressure fan, and then transported to the treatment equipment through pipelines to purify the waste gas.

[0003] In the process of transmitting and pressurizing exhaust gas in the prior art, since the exhaust gas contains a large amount of pollutants, some of the pollutants will adhere to the inner wall of the pipe during transmission. The pollutants will clog the pipe and reduce the effective cross-sectional area of ​​the pipe. In the long run, the pollutants accumulated on the inner wall of the pipe will increase the friction resistance of the exhaust gas in the pipe, resulting in increased transmission resistance, reduced transmission efficiency, and increased transmission energy consumption.

[0004] In view of this, we propose a transmission and pressurization device for exhaust gas treatment. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The present application provides a transmission and pressurizing device for waste gas treatment, which includes a mounting base 1, a high-pressure fan 2 and a controller are installed on the upper surface of the mounting base 1, and the controller and the high-pressure fan 2 are electrically connected. The high-pressure fan 2 is arranged in a pipeline for conveying waste gas.

[0025] Among them, a cleaning mechanism is provided on the exhaust gas conveying pipeline to clean the pollutants attached to the inner wall of the pipeline through the cleaning mechanism;

[0026] The cleaning mechanism includes an inner ring 11 and an outer ring 13, which are magnetically connected. The inner ring 11 is arranged in the pipeline, and the outer diameter of the inner ring 11 is close to the inner diameter of the pipeline. Scraping wings 12 are arranged on both sides of the inner ring 11. When the scraping wings 12 move in the inner ring 11, they can scrape the attachments on the inner wall of the pipeline, thereby facilitating the scraping of pollutants inside the pipeline. A circle of flexible magnetic strips 14 is fixed on the outer wall of the inner ring 11, and the flexible magnetic strips 14 are located in the middle position of the outer wall of the inner ring 11. The outer ring 13 is sleeved on the outer wall of the pipeline, and another flexible magnetic strip 14 is fixed on the inner wall of the outer ring 13. Through the magnetic connection between the two groups of flexible magnetic strips 14, the outer ring 13 can control the inner ring 11 and the scraping wings 12 to move on the inner wall of the pipeline without affecting the space on the inner wall of the pipeline, thereby ensuring the normal gas transmission function of the pipeline to a certain extent.

[0027] A sleeve block 15 is fixed to the outer wall of one side of the outer ring 13, and a reciprocating screw 16 is inserted into the sleeve block 15 through a thread. Both ends of each group of reciprocating screws 16 are rotatably connected to a support seat 20 through a bearing, and the support seat 20 is fixedly installed on the upper surface of the mounting seat 1, wherein a bracket is also fixed above the mounting seat 1, and a motor 17 is installed on the bracket. The output end of the motor 17 is fixed to one end of the reciprocating screw 16 through a coupling. The reciprocating screw 16 is rotated by the drive of the motor 17, so that the sleeve block 15 drives the outer ring 13 to reciprocate back and forth. A gas flow meter 5 is installed on the pipeline. The gas flow meter 5 and the motor 17 are electrically connected to the controller. The gas pressure passing through the pipeline can be monitored by the gas flow meter 5. When the pressure is detected to be lower than the set value, a signal can be sent to the controller, and the motor 17 can be controlled by the controller to start, so that the scraper 12 can be driven to move in time to clean the inner wall of the pipeline, thereby timely reducing the pollutants attached to the inner wall of the pipeline, which has the advantage of improving the transmission efficiency.

[0028] It is worth noting that a sliding block 18 is fixed to the outer wall of the other side of the outer ring 13, and a sliding rod 19 is movably penetrated through the inner wall of the sliding block 18. The mutual cooperation between the sliding block 18 and the sliding rod 19 can realize the limitation of the outer ring 13, so that the outer ring 13 is more stable during the movement, and another support seat 20 is fixed at both ends of the sliding rod 19, and the other support seat 20 is also fixedly installed on the upper surface of the mounting seat 1, and the other support seat 20 can be used to support the sliding rod 19.

[0029] Reference Figure 1 , Figure 5 and Figure 6 A recovery mechanism is provided at the bottom of the pipeline to collect the cleaned pollutants through the recovery mechanism;

[0030] The recovery mechanism includes a feed pipe 21, a feed port is provided at the bottom of the pipe, the feed pipe 21 is fixed in the feed port, a collection cover 22 is provided at the bottom of the feed pipe 21 through a threaded sleeve, and the collection cover 22 can be conveniently rotated and disassembled by providing mutually matching threads on the outer wall of the bottom end of the feed pipe 21 and the inner wall of the top end of the collection cover 22;

[0031] It is worth noting that a sealing gasket 23 is glued around the inner wall of each set of aggregate covers 22, and the sealing gasket 23 is in sealing contact with the bottom end of the feed pipe 21. The sealing gasket 23 can be used to seal the connection between the feed pipe 21 and the aggregate cover 22.

[0032] The implementation principle of a transmission and pressurizing device for waste gas treatment in the embodiment of the present application is as follows:

[0033] First, the controller controls the high-pressure blower 2 to start, so that the exhaust gas is pressurized and transmitted through the pipeline. During the process of pressurized exhaust gas transmission, the gas flow meter 5 is used to monitor the gas transmission pressure. When the pressure is detected to be lower than the set value, a signal can be sent to the controller. At this time, the controller receives the signal and sends a command to the motor 17, thereby controlling the motor 17 to start. As the motor 17 starts, the reciprocating screw 16 rotates. At this time, the sleeve block 15 is displaced under the rotation of the reciprocating screw 16, and the outer ring 13 is reciprocated on the surface of the pipeline under the limiting action of the sliding block 18 and the sliding rod 19. Through the magnetic attraction between the flexible magnetic strips 14, the inner ring 11 is controlled to drive the scraper 12 to move on the inner wall of the pipeline, so that the inner wall of the pipeline can be cleaned in time to reduce pollutants attached to the inner wall of the pipeline.

[0034] Secondly, during the cleaning process, as the waste gas is continuously pressurized and transported, the attachments scraped off pass through the discharge port along the flow direction of the waste gas, and finally enter the aggregate cover 22 through the discharge pipe 21 for collection. When the aggregate cover 22 needs to be cleaned, it only needs to be rotated to achieve the disassembly and cleaning of the aggregate cover 22.

[0035] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
