Description

Technical Field

[0001] The present invention relates to the technical field of shell-and-tube heat exchangers, and specifically to a self-cleaning primary filter device for an adsorption cabinet. Background Art

[0002] An adsorption device refers to a device that uses the adsorption ability of a solid to a gas to purify harmful gases. Adsorption is the diffusion process of harmful gases in contact with a certain solid substance at the interface. In the adsorption phenomenon, the solid substance with a relatively large adsorption capacity is called an adsorbent, and the substance to be adsorbed is called an adsorbate.

[0003] During the daily use of an adsorption device, it is often necessary to use an adsorption cabinet as an auxiliary. During the daily use of the adsorption cabinet, it is necessary to automatically clean the impurities inside the adsorption cabinet through a filtering device to meet the subsequent need for the adsorption cabinet to adsorb and purify gases for a long time, and to improve the adsorption quality of the adsorption cabinet during long-term use.

[0004] The existing Chinese patent application with the publication number CN110639298B discloses an air purifier with self-cleaning function and space-saving, including a body with an air inlet and an air outlet. A filtering device is provided inside the body, and the filtering device divides the interior of the body into an air inlet chamber connected to the air inlet and an air outlet chamber connected to the air outlet. The filtering device at least includes a primary filter plate located in the air inlet chamber. The primary filter plate is inclined in the body and is arranged at an acute angle with the horizontal plane; both the air inlet and the air outlet are vertically upward; a waste residue chamber is further provided inside the body below the filtering device. The top of the waste residue chamber is connected to the bottom of the filtering device, and a waste residue port for waste residue to fall into is opened on the waste residue chamber. This air purifier has the characteristics of self-discharge and self-cleaning, occupies a small space, has a high effective utilization rate, a complete overall function, and strong practicability.

[0005] There is a Chinese patent application with the publication number CN210874702U, which discloses an air filtration device for a pressure swing adsorption oxygen generator, including a housing, and an electrostatic adsorption device, a primary filter screen, an air drying device, a heating device, and a fan sequentially arranged inside the housing. The side wall bottom of the housing is respectively provided with a first air duct and a second air duct, and control valves are installed on both the first air duct and the second air duct. The installation position of the fan inside the housing is higher than the first air duct and the second air duct. This utility model, by setting independent air filtration and air drying devices, sends clean and dry air into the pressure swing adsorption oxygen generator, which is beneficial to reducing the structural complexity of the adsorption tank and reducing maintenance costs; setting a heating device is beneficial to accelerating the regeneration of activated alumina and improving the equipment usage efficiency; setting an electrostatic adsorption device cooperating with the air filtration device is beneficial to adsorbing dust and sundries on the primary filter screen and blowing them out through the fan, achieving the effect of automatically cleaning the primary filter screen.

[0006] However, the adsorption cabinet has the following defects during specific use:

[0007] 1. During daily use of the existing adsorption cabinet, although it can perform good adsorption operations on gases, the automatic scraping effect of impurities falling on the inner wall of the adsorption cabinet is not high. Moreover, when automatically scraping the impurities on the inner wall of the adsorption cabinet, the linkage opening effect of the cabinet door of the adsorption cabinet is not high, reducing the linkage effect of automatically cleaning and discharging the impurities on the inner wall of the adsorption cabinet. And, after automatically scraping and cleaning the impurities in the adsorption cabinet, the linkage closing and sealing effect of the input port is not high, resulting in gas input during the automatic cleaning of the impurities on the inner wall of the adsorption cabinet, causing dust to be raised and reducing the automatic cleaning effect of the impurities on the inner wall of the adsorption cabinet.

[0008] 2. During daily filtration use of the existing adsorption cabinet, the adsorption net is often directly installed inside the adsorption cabinet. The effect of automatically patting the impurities adsorbed on the surface of the adsorption net and making them fall onto the inner side wall of the adsorption cabinet is not high. As a result, during long-term daily use of the adsorption cabinet, the adsorption net will become blocked inside the adsorption cabinet, reducing the gas filtration effect. At the same time, during long-term use of the adsorption net, the clamping and disassembly effect of the adsorption net on the surface of the installation track is not high, reducing the convenience for construction personnel to disassemble and replace the adsorption net.
