Embodiment 1

[0050] 1) Preparation method of non-woven fabric impregnated with quaternary ammonium salt solution:

[0051] The present invention selects the fiber average diameter as 60-100 μ m, gram weight as 20-50 g / m 2 Alginate fiber non-woven fabric with a thickness of at least 2mm, prepare a quaternary ammonium salt solution, the molar concentration of the solution is 0.1-0.3mol / L, immerse the non-woven fabric in the quaternary ammonium salt solution for 10-30min and take it out at 110-130°C Dry for 10-20min, that's it. The quaternary ammonium salt used is preferably octadecyl dimethyl hydroxyethyl quaternary ammonium nitrate, which has a good antistatic effect when used in conjunction with calcium alginate fiber non-woven fabrics. It is tested according to GB10064 at an air humidity of 40%. Under certain conditions, the surface resistance can reach 2.3×10 7 Ω. When octadecyl dimethyl hydroxyethyl quaternary ammonium nitrate is used in conjunction with cotton fiber non-woven fabric...

Embodiment 2

[0057] 1) Filter preparation method:

[0058] Cut each layer of non-woven fabric, fiber net and sponge prepared by the above-mentioned method to a suitable size and shape, and heat press along the edge to obtain a filter net. The filter screen can be combined with the filter screen support by gluing; or the four sides of the filter screen can be bonded with magnetic components, the filter screen support is provided with magnetic components of opposite polarity, and the filter screen and the filter screen support are combined through magnetic components.

[0059] 2) The prepared filter has the property of effectively blocking dust and particulate matter and is easy to desorb dust and particulate matter. In the case of normal use for a week without dust removal or purging, the dust removal unit is not turned on, and the filter is only purged with normal wind for about 3 minutes. There is no visible dust or particle adsorption on the surface of the filter; After the filter is pu...

Abstract

The invention relates to a self-cleaning device of a dust filtering part. The self-cleaning device comprises a fresh air channel, an air exhausting channel, the dust filtering part and further comprises a driving device, wherein the fresh air channel and the air exhausting channel are adjacently arranged side by side, and a mutual communicating through groove is formed between the fresh air channel and the air exhausting channel; and the driving device can drive the dust filtering part to penetrate through the through groove in the radial direction of the fresh air channel and the air exhausting channel to do reciprocating motion. According to the device, the dust filtering part carried by a moving part can be driven by the driving part to do reciprocating motion in the adjacent channel, so that the fresh air system can filter dust while the fresh air is circulated, and the dust filtering part does not need to be cleaned and replaced frequently, so that the use cost of the fresh air system is reduced, and the convenience and the cleanliness are improved.

Description

technical field [0001] The invention relates to the technical field of fresh air systems, in particular to a self-cleaning device for dust filter components and a fresh air system. Background technique [0002] The fresh air system is a new type of indoor ventilation and exhaust equipment, which belongs to an open circulation system, allowing people to breathe fresh, clean and high-quality air indoors. It is based on the principle of sending fresh air to the room with special equipment on one side of the airtight room, and then exhausting it from the other side to the outside by special equipment, forming a "fresh air flow field" indoors to meet the needs of indoor fresh air ventilation. Previously, some special fresh air systems and special dust collection system equipment appeared on the market, which ensured a healthy living environment to a certain extent, but the two sets of fresh air and dust removal systems are independent, complex in structure, expensive in cost, and...
