Magnetizing regeneration based air purifying device

Abstract

The invention discloses a magnetizing regeneration based air purifying device. The magnetizing regeneration based air purifying device comprises a purifying layer and a regeneration control layer, wherein the purifying layer comprises a gas inlet chamber (1), an air purifying chamber (2) and a gas exhaust chamber (3) which sequentially communicate with one another, a gas inlet valve (6) is arranged in the gas inlet chamber (1), a gas exhaust valve (8) is arranged in the gas exhaust chamber (3), and a purifying medium (7), a fan and a magnetizing device (15) are arranged in the air purifying chamber (2); the regeneration control layer comprises a negative-pressure regeneration chamber (4), a first partition (5) is arranged between the negative-pressure regeneration chamber (4) and the air purifying chamber (2), an opening (9) for enabling the negative-pressure regeneration chamber (4) to communicate with the air purifying chamber (2) is formed in the first partition (5); and a vacuum pump (10) is arranged in the negative-pressure regeneration chamber (4). The magnetizing regeneration based air purifying device does not need to take out the purifying medium from the air purifying device, so that negative-pressure regeneration of the purifying medium can be completed, and therefore, regeneration efficiency of the purifying medium is remarkably improved.

Description

technical field [0001] The invention relates to the field of air purification, in particular to an air purification device based on magnetization regeneration. Background technique [0002] Air pollution refers to the phenomenon that certain substances enter the atmosphere due to human activities or natural processes, present a sufficient concentration and reach a sufficient time, and thus endanger human comfort, health and welfare or the environment; as my country's industrial Air pollution has become an urgent problem to be solved. [0003] There are many types of air pollutants, and their forms may be solid particles, liquid droplets or gases, or a mixture of these forms; for now, in addition to solid pollution, air pollution is mainly reflected in Toxic and harmful gases, such as NO 2 , SO 2 , O 3 etc. For solid particle pollutants, filter screens are generally used to filter them out. For toxic and harmful gases, it is generally necessary to use purification media (u...

Problems solved by technology

[0003] There are many types of air pollutants, and their forms may be solid particles, liquid droplets or gases, or a mixture of these forms; for now, in addition to solid pollution, air pollution is mainly reflected in Toxic and harmful gases, such as NO 2 , SO 2 , O 3 etc. For solid particle pollutants, filter screens are generally used to filter them out. For toxic and harmful gases, it is generally necessary to use purification media (usually activated carbon) in the air purification device for adsorption; when using purification media to adsorb toxic and harmful gases In the process of air purification, due to the limited adsorption capacity of the purification medium, it will enter a saturated state after absorbing a certain amount of harmful gas. At this time, the purification medium in the air purification device can only be replaced, or the purification medium can be taken out. After the regeneration process, it is put back into the air purification device. However, whether it is to replace the purification medium or perform regeneration treatment on the purification medium, the purification medium needs to be taken out from the air purification device, which brings difficulties to the use of the air purification device. many inconveniences

[0004] The medium regeneration process is essentially to make the purification medium release the toxic and harmful gas adsorbed, and regain the adsorption capacity; if the medium regeneration is performed directly in the air purification device, there will be problems of low medium regeneration efficiency and poor effect
