Problems solved by technology

However, this patent has the following disadvantages: the polarization electric field generated by the metal mesh is weaker than that of the metal plate. In theory, a higher polarization voltage or a shorter polarization distance is required to achieve the polarization field strength formed by the metal plate. Level
However, this device is still an electrostatic precipitator in essence, and the particles are directly collected by the metal plate, which still has the disadvantages of an electrostatic precipitator: complex structure, easy to generate ozone, and rapid decline in long-term use efficiency

Abstract

The invention provides a filter material polarization module for an air filtering device and the air filtering device. The filter material polarization module comprises a filter screen (4) and can polarize the filter screen (4), and gas containing particulate matter can pass through the filter screen (4) so that the particulate matter can be at least partially left in the filter screen (4). The filter material polarization module comprises a high-voltage direct-current power supply (1), a first electrode plate (2) and a second electrode plate (3), wherein the filter screen (4) is positioned between the first electrode plate (2) and the second electrode plate (3). The first electrode plate (2) and the second electrode plate (3) are connected with the high-voltage direct-current power supply (1) to form an electric field, so the filter screen (4) is polarized. And an insulating layer (5) is arranged on one surface, facing the filter screen (4), of only one of the first electrode plate (2) and the second electrode plate (3).

Description

technical field [0001] The application belongs to the technical field of indoor air purification, and in particular relates to a filter material polarization module and an air filter device used in an air filter device. Background technique [0002] China's rapid economic and social development has brought serious burdens to the environment. For example, the outdoor air particulate matter pollution situation is very serious. [0003] Particles from outside can enter the room through natural ventilation or mechanical ventilation systems. In modern society, people spend more than 80% of their life time staying, working and living indoors, and the exposure of indoor people to particulate matter is very considerable. Numerous studies have shown that particulate matter has serious effects on human health. Clinical symptoms caused by particulate matter exposure include allergic rhinitis and respiratory inflammation induced by plant pollen, cancer caused by heavy metal salts, ox...
