Problems solved by technology
However, the amount of charge generated by this frictional electrification method is very limited; the continuous movement of the equipment consumes a lot of energy; it will inevitably produce movement noise; the stability of the continuous movement equipment is low; its charging of uncharged dust in the air Low efficiency and adsorption efficiency
[0007] Therefore, in view of the shortcomings of the existing high-voltage electrostatic precipitator technology, such as low dust removal efficiency, easy generation of ozone, and high filter resistance of HEPA high-efficiency filter technology, a low-voltage electrostatic precipitator filter is designed and manufactured to make it both electrostatic precipitator. The advantages of low filter resistance and high efficiency of non-woven fabric filter, and completely avoid the generation of ozone, energy saving and environmental protection, good stability, washable and reusable, have important economic and social benefits

specific Embodiment approach 1
[0070] Embodiment one: the preparation method of the needle-punched conductive non-woven fabric filter screen for low-voltage electrostatic dust removal comprises the following steps:
[0071] (1) take by weighing the chopped polypropylene fiber 30kg of the chopped carbon black fiber 70kg of 2.5dtex and the chopped polypropylene fiber of 2.0dtex respectively;
[0072] (2) feed the opener after mixing the above fibers, and open and remove impurities;
[0073] (3) Feed the above-mentioned fully mixed and loosened fibers into a carding machine to form a web, and control the grammage of the single-layer fiber web to be 10-20g / m 2 ;
[0074] (4) The single-layer fiber web is transported to the web-laying machine through the output curtain for cross-laying. By changing the speed ratio of the web-laying trolley in different sections of the one-way trip, the horizontal weight of the web is guaranteed to be uniform. The speed of the output curtain is 18 layers to obtain the output fi...

Abstract
The invention discloses a method and a system for manufacturing a needle-punched conductive nonwoven cloth filter net for low-pressure electrostatic dedusting and application. A low-pressure electrostatic dedusting type fresh air system or an air purifier using the manufactured needle-punched conductive nonwoven cloth filter net has the advantages that the generation of ozone can be completely avoided, the filter drag is low, the cost is low, the dust containing amount is large, and the like. The needle-punched conductive nonwoven cloth filter net has the advantages that the strength is high,the stability is good, and the needle-punched conductive nonwoven cloth filter net can be repeatedly cleaned and recycled.
Description
technical field [0001] The invention relates to a manufacturing method, system and application of a needle-punched conductive non-woven filter screen for low-voltage electrostatic dust removal. Background technique [0002] More and more people begin to pay attention to air quality, and indoor air purification products are gradually favored by the masses. Among them, electrostatic dust removal technology is gradually applied to fresh air systems and air purification products for dust removal and sterilization in large office buildings, hotels, hospitals and homes. . Compared with the traditional use of HEPA high-efficiency filters, the significant advantage of electrostatic dust removal technology is that high-voltage static electricity can kill bacteria and viruses in the air while adsorbing particles, and the dust collection plate of electrostatic dust removal can be disassembled and cleaned, and the service life Long, greatly reducing the replacement cost of the filter. ...
