Embodiment Construction

[0038] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0039] The invention provides a method for the electrocoagulation of fine particles of outdoor fresh air and indoor air, referring to figure 1, the air to be purified is removed through the pre-dust removal area to remove large particles that may cause unstable discharge in the electrocoagulation area, and then introduced into the electrocoagulation area of ​​the present invention. In the electrocoagulation area, according to the treatment object and the required coagulation effect, the airflow passes successively One or more ionized charge-coagulate and grow segments. In each ionization charge-coagulation growth section, the fine particles contained in the airflow are respectively charged with opposite polar charges in the high-voltage discharge field with opposite polarities, and then the particles with opposite polar charges are brought into contact to realize coa...

Abstract

The invention discloses a method and device for electric agglomeration of outdoor fresh air and indoor air fine particles, and belong to the technical field of electrostatic precipitation. According to the method and device for the electric agglomeration of the outdoor fresh air and indoor air fine particles, an electric agglomeration zone is arranged between a pre-dedusting zone and an efficientdedusting zone to realize the removal of electric agglomeration of fine particles in airflow. The electric agglomeration zone comprises one or more ionizing charging-agglomeration growth sections. Theionization charging-agglomeration growth section is realized by four ways, specifically, wire-plate electrode configuration, wire-plate electrode configuration matched with a current-guiding column,wire-tube electrode configuration and wire-tube electrode configuration matched with the current-guiding column, and a whole assembly is usually formed. The invention has the advantages of simple structure, convenient maintenance and low air flow resistance, and the removal efficiency for the fine particles is improved.

Description

technical field [0001] The invention belongs to the technical field of electrostatic dust removal, and relates to a technology for purifying fine particles of outdoor fresh air and indoor circulating air, in particular to a method and device for electrocoagulation of outdoor fresh air and indoor air fine particles. Background technique [0002] At present, fine particles (particles with an aerodynamic diameter of less than 2.5 μm) have become the primary air pollutants in many cities in my country. Similarly, fine particles are also one of the main indoor pollutants. With the development of my country's economy and the strengthening of people's awareness of environmental protection, they pay more and more attention to the indoor living and working environment, especially the indoor air quality. Epidemiological and toxicological studies have shown that reducing the concentration of particulate pollutants can significantly improve the level of health. Because of this, cost-ef...
