Air purification device

Abstract

The invention relates to an air purification device, particularly used for removing harmful gas in the air and aiming to solve the desorption problem of adsorbent in the air purification device, thereby renewable adsorbent can be utilized to continuously adsorb the harmful gas in the air. The invention adopts the technical means as follows: a heating element is arranged in a main duct near the adsorption unit part and forms a high-temperature region in the main duct; a thermal insulation layer is arranged on the side wall of the high-temperature region; an air door is respectively arranged at both ends of the high-temperature region; an adsorption unit and the heating element are at least arranged in the high-temperature region; a polluted air exhaust port and a circulating air port are respectively arranged at both sides of the adsorption unit; the circulating air port is arranged at the side provided with the heating element; the air inlet end of a pollution discharge fan is communicated with the polluted air exhaust port; the exhaust end is divided into two ways, one way is led to the circulating air port through a circulating air door and a circulating air tube, and the other way is communicated with the outdoors through a pollution discharge air door and a pollution discharge air tube.

Description

technical field [0001] The invention relates to an air cleaning device, in particular to an air cleaning device for removing harmful gases in the air. Background technique [0002] Generally speaking, air pollution can be divided into two categories: harmful gases (such as sulfur dioxide, carbon monoxide, formaldehyde, benzene compounds, etc.) and inhalable particles. Filters, electrostatic precipitators, etc. can be used to remove inhalable particles in the air. The removal of harmful gases in the air can be roughly divided into the following types according to the prior art: [0003] Chemical adsorption method: use specific chemical agents to immobilize through an irreversible chemical reaction with harmful gases in the air. The disadvantage is that one agent can only be effective with one or several harmful gas components, showing very strong selectivity. Harmful gases with relatively stable chemical properties are difficult to remove by chemical adsorption at normal tem...
