Problems solved by technology

Mechanical filter indoor air purifiers can only filter particulate matter in the air, and have little effect on the purification of harmful gases; activated carbon adsorption indoor air purifiers can effectively remove pollutants and obtain clean air, but they need to be replaced frequently The replaced adsorbent will pollute the environment; although the air negative ion indoor air purifier can freshen the air, it is not obvious for the removal of formaldehyde, benzene and other organic pollutants in the air, which is the limitation of the prior art. defect

Abstract

The invention provides an indoor air-purification device, comprising a case, a control system, an induced draught system, an absorption system and a catalytic combustion system; the air containing harmful substances flows into the absorption system to realize the indoor air purification by the induced draught system at normal temperature. Absorption materials are heated, and the harmful substances desorbed from the absorption materials are processed by catalyst in the catalytic combustion system, and the indoor harmful substances, namely, the pollutants, such as carbon monoxide, benzene, toluol, dimethyl-benzene, formaldehyde, ethyl acetate and the like are completely transformed into carbon dioxide and water. The process can be repeatedly carried out; the absorption materials achieve in-situ regeneration by heating. Compared with the traditional adsorption method, the device does not need to replace any expendable; after the device is operated for 24 hours in a room of 50m <3> with the formaldehyde density of 1.4mg / m<3>, the formaldehyde density is detected to be 0.06mg / m<3> by using a phenol reagent, lower than 0.10mg / m<3> which is specified by Chinese industrial standards.

Description

technical field [0001] The invention relates to an indoor air purification device, in particular to an air purification device which can effectively eliminate organic pollutants in indoor air. Background technique [0002] At present, the actual application of indoor air purifiers includes: mechanical filter indoor air purifier, activated carbon adsorption indoor air purifier and air negative ion indoor air purifier. Mechanical filter indoor air purifiers can only filter particulate matter in the air, and have little effect on the purification of harmful gases; activated carbon adsorption indoor air purifiers can effectively remove pollutants and obtain clean air, but they need to be replaced frequently The replaced adsorbent will pollute the environment; although the air negative ion indoor air purifier can freshen the air, it is not obvious for the removal of formaldehyde, benzene and other organic pollutants in the air, which is the limitation of the prior art. defect. ...
