Problems solved by technology

This presents a disadvantage to the prior art in that some particles so ionized may not return to the air inlet, and particles that do return to the air inlet may lose some or all of their charge before returning

Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0015] Such as figure 1 As shown, the present invention relates to an air filter device, comprising a pre-filter 1, an ionization zone 2, a collection zone 3 and a post-filter 4 arranged from outside to inside, and the shown pre-filter 1 is composed of two layers of gauze The structure is composed of coarse gauze and fine gauze, the aperture of the coarse gauze is 10000-15000nm, the aperture of the fine gauze is 5000-8000nm, most of the larger diameter particulate matter in the air passes through the The ionization zone 2 is composed of several polar ionization plates arranged at intervals, an ionization field is formed between two adjacent polar plates, and the fine particles passing through the pre-filter 1 Ionization is carried out in the ionization area 2, and it is decomposed into ions of different polarities. The collection area 3 is co...

Abstract

The invention relates to an air filtering device. The air filtering device is characterized by comprising a front filter (1), an ionization area (2), a collection area (3) and a rear filter (4), all of which are arranged from exterior to interior; the front filter (1) is composed of a two-layer gauze structure including a rough-level gauze and a fine-level gauze; the ionization area (2) is composed of a plurality of polarity ionization plates arranged at intervals, and an ionization field is formed between every two adjacent polarity ionization plates; the collection area (3) is composed of aplurality of polarity collection plates different in polarity so that the ionization area (2) can be used for adsorbing ions obtained after particle ionization to the polarity collection plates; and the rear filter (4) is composed of an air filter film. According to the air filtering device, the air ionization technology is added, particulate matter electrified separation is achieved, the electrified collection plates are used for collecting ionized particles, the front filter and the rear filter can effectively isolate particles different in diameter and size, and the air filtering quality iseffectively improved.

Description

technical field [0001] The invention relates to the field of air purification systems, in particular to an air filter device. Background technique [0002] Air with a high concentration of suspended particulates (hereinafter, "dirty air") presents a health hazard to life breathing dirty air. Dirty air can also cause higher deposition rates of deposited suspended particles (eg, dust), thus resulting in the need for more frequent cleaning of surfaces that are expected to be kept clean (eg, surfaces within the home). [0003] Conventional air cleaners can remove particles from the air by trapping them in a filter such as a filter air cleaner (FAC), or by collecting them in a filter such as an electrostatic precipitator (ESPAC). plate. The filter or plate can then be discarded, cleaned or replaced. [0004] Since the ionizer imparts an electric charge on the particles and ions as they exit the purifier, the so charged ions must travel back to the air inlet of a conventional e...
