Description

Technical Field

[0001] The invention relates to the technical field related to shell and tube heat exchangers, and in particular to a self-cleaning primary filtering device for an adsorption cabinet. Background Art

[0002] Adsorption equipment refers to equipment that uses the adsorption capacity of solids to purify harmful gases. Adsorption is the diffusion process of harmful gases on the interface when they come into contact with a certain solid substance. In the adsorption phenomenon, the solid substance with greater adsorption capacity is called adsorbent, and the adsorbed substance is called adsorbate.

[0003] In the daily use of adsorption equipment, it is often necessary to use an adsorption cabinet to assist in its use. In the daily use of the adsorption cabinet, it is necessary to use a filtering device to automatically clean the impurities inside the adsorption cabinet to meet the subsequent long-term gas adsorption and purification needs of the adsorption cabinet and to improve the adsorption quality of the adsorption cabinet under long-term use.

[0004] The existing Chinese patent application with publication number CN110639298B discloses an air purifier with self-cleaning function and saving space, including a body with an air inlet and an air outlet, a filtering device is arranged in the body, 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 tiltedly arranged in the body, and the primary filter plate is arranged at an acute angle to the horizontal plane; the air inlet and the air outlet are both arranged vertically upward; a waste residue chamber is also arranged in 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 opening is opened on the waste residue chamber for waste residue to fall into. The air purifier has the characteristics of self-drainage and self-cleaning, and the equipment occupies a small space, has a high effective utilization rate, has complete overall functions, and is highly practical.

[0005] The existing Chinese patent application with publication number CN210874702U discloses an air filtering device for a pressure swing adsorption oxygen generator, comprising a shell, and an electrostatic adsorption device, a primary filter, an air drying device, a heating device, and a fan which are sequentially arranged inside the shell. A first air duct and a second air duct are respectively opened at the bottom of the side wall of the shell, and control valves are installed on the first air duct and the second air duct. The installation position of the fan in the shell is higher than the first air duct and the second air duct. The utility model sends clean and dry air into the pressure swing adsorption oxygen generator by arranging independent air filtering and air drying devices, which is beneficial to reducing the structural complexity of the adsorption tank and reducing maintenance costs; arranging a heating device is beneficial to accelerating the regeneration of activated alumina and improving the use efficiency of the equipment; arranging an electrostatic adsorption device in conjunction with the air filtering device is beneficial to absorbing dust and debris on the primary filter and blowing them out through the fan, so as to achieve the effect of automatically cleaning the primary filter.

[0006] However, the adsorption cabinet has the following defects when used:

[0007] 1. The existing adsorption cabinet can perform good adsorption operation on gas in daily use, but the automatic scraping effect of impurities dropped from the inner wall of the adsorption cabinet is not high, and when the impurities on the inner wall of the adsorption cabinet are automatically scraped, the linkage opening effect of the cabinet door of the adsorption cabinet is not high, which reduces the linkage effect of automatic cleaning and automatic discharge of impurities on the inner wall of the adsorption cabinet. Moreover, after the impurities in the adsorption cabinet are automatically scraped and cleaned, the linkage closing and sealing effect of the input port is not high, so that when the impurities on the inner wall of the adsorption cabinet are automatically cleaned, gas input will be caused, causing dust to be raised, reducing the automatic cleaning effect of impurities on the inner wall of the adsorption cabinet;

[0008] 2. When the existing adsorption cabinet is used for daily filtering, the adsorption net is often directly installed in the adsorption cabinet for use. For the impurities adsorbed on the surface of the adsorption net, the automatic slapping and dropping to the inner wall of the adsorption cabinet is not very effective, so that when the adsorption cabinet is used for a long time in daily life, the adsorption net will be blocked in the adsorption cabinet, reducing the effect of gas filtration. At the same time, when the adsorption net is used for a long time, the effect of the engagement and disassembly of the adsorption net on the surface of the installation track is not good, which reduces the convenience of construction personnel in disassembling and replacing the adsorption net.
