Abstract

The invention discloses a pulse corona plasma based air purification ventilating window. The air purification ventilating window comprises a size-adjustable window-shaped housing and a power source module connected thereto; the window-shaped housing can be divided into a lower air inlet chamber, an intermediate plasma processing chamber, and an upper fan; a physical filtering screen is arranged between the air inlet chamber and the plasma processing chamber; and an ozone filtering screen is disposed between the plasma processing chamber and the fan. The air inlet chamber comprises an inner airinlet and an outer air inlet, wherein a push plate is arranged in the inner air inlet; in the plasma processing chamber, corrosion-resistant metal wires and corrosion-resistant metal plates are longitudinally and alternatively arranged on a plane of the plasma processing cavity to form a discharge electrode; the metal wires are mutually connected in parallel to form a cathode, and the metal plates are mutually connected in parallel to form an anode. The invention can realize indoor air circulation purification of the conventional air purifiers, can realize the renewal of the indoor air. The invention adopts a pulse corona discharge structure, which can generate low temperature plasma to treat contaminated organic matters and can achieve electrostatic dust removal.

Description

technical field [0001] The invention belongs to the technical field of air purification and relates to an air purification ventilation window based on pulsed corona plasma. Background technique [0002] In recent years, with the frequent occurrence of air pollution problems, the pollution problem has received strong international and domestic attention and widespread attention. The severity and complexity of air pollution problems in mainland cities are astounding, and indoor pollution is often more serious. Due to the relatively closed indoor environment with poor ventilation, it is difficult to discharge foreign pollutants or pollutants from indoor pollution sources in a short time. Although traditional air purification technology is widely used in the market, there are still deficiencies: the mechanical filter type purification technology filters dust through the particle filter and organic filter, but the wind resistance caused by the filter is too dense will increase th...

Problems solved by technology

Although traditional air purification technology is widely used in the market, there are still deficiencies: the mechanical filter type purification technology filters dust through the particle filter and organic filter, but the wind resistance caused by the filter is too dense will increase the noise and reduce the life of the filter; The high-voltage electrostatic dust collection technology uses a high-voltage electrostatic field to ionize the gas, so that the dust particles are charged and adsorbed to the electrodes, ensuring the air volume and adsorbing fine particles at the same time, but the capture effect on larger particles and fibers is poor and cleaning is troublesome and time-consuming; electrostatic electret The type purification technology has the advantages of electrostatic dust removal and low wind resistance, and can effectively remove particles above 10 microns compared with the mechanical filter, but when the particle size is as small as 5 microns, the high-efficiency mechanical filtration system is very expensive; Electrostatic sterilization technology uses a high-voltage electrostatic field of thousands of volts to instantly kill bacteria and viruses attached to the dust, but the effect of trapping larger particles and fibers is poor, and secondary pollution caused by ozone generated by high voltage is unavoidable

[0005] To sum up, although the existing indoor air purifiers have been able to remove pollutants in the air with high efficiency while occupying a small space, they are only suitable for closed spaces with limited volume, and the requirements for sealing It means that the existing air purifiers cannot ventilate the room during the working period, which has relatively large limitations and cannot handle the organic pollutant gases in the haze. Therefore, it is necessary to design a pulsed corona discharge plasma , a convenient purification device that can simultaneously solve outdoor to indoor air circulation and indoor air self-circulation is particularly necessary
