Self-circulation chemical air filtering method and filtering equipment thereof

Abstract

The invention discloses a self-circulation chemical air filtering method and filtering equipment thereof. The filtering equipment comprises a filtering equipment box body, a primary filter, a chemical filtering segment A, a blower, a chemical filtering segment B and a medium efficiency filter; the filtering equipment box body is of a vertical square structure, and the air inlet segment is composed of an air inlet shutter; the primary segment is formed by the primary filter, and the medium efficiency segment is formed by the medium efficiency filter; the air outlet segment is composed of an air outlet shutter; the chemical filtering segment A is welded and fixed above the primary segment, a blower segment is welded and fixed above the chemical filtering segment A, and the blower and a blower base are arranged in the blower segment; access doors are arranged at parts corresponding to the functional segments on the facade of the filtering equipment box body; the filtering equipment disclosed by the invention can be independently arranged indoors, the manufacturing cost is low, the installation is simple, and PM10 and PM2.5 granules and such chemical gases as SO2, NOx, formaldehyde, VOC can be effectively removed; the self-circulation air quantity is large enough to solve the problem that a fresh air filtering system cannot effectively purify indoor air.

Description

Technical field [0001] The invention relates to the field of air filtration and purification treatment technical equipment, in particular to a self-circulating air chemical filtering method and filtering equipment thereof. Background technique [0002] With the advancement of industrialization and science and technology, air pollution has become more and more serious. Gases such as PM10, PM2.5, sulfur dioxide, nitrogen oxides, formaldehyde, and VOC often exceed the standard. Industry, automobile exhaust, building materials, etc. release a large amount of toxic and harmful substances, which cause great harm to the human body and precision instruments. Therefore, the toxic and harmful substances must be purified. [0003] The existing technology mainly filters and purifies outdoor air through special filtering and purification equipment, or adding a filtering function section to the air-conditioning box; after filtering through the fresh air filtering equipment, the outdoor fresh air...
