Description
Technical field
The present invention relates to a kind of electret formula polypropylene thermoplastic rod electrostatic precipitation filter, particularly a kind of air cleaning unit that electret formula polypropylene thermoplastic rod electrostatic precipitation filtering technique is applied to civilian central air-conditioning ventilating system and clean air-conditioning system.
Background technology
The air-conditioning system of clean industry and civil buildings need be carried out purified treatment to pollutants such as the dust that is contained in the air, fine particles, bacteriums because of the cleanliness factor requirement in air handling process; At present, many air-conditioning systems all are to adopt materials such as common non-woven fabric, static nonwoven, glass fibre as air filting material, but owing to common non-woven fabric, glass fibre are to clean; Basically be disposable use; Though and that static class nonwoven has the static electricity is severe, in use also static is severe to be subdued because of the influence of working environment produces for it, also can only carry out 2 to 3 service life and clean the back and just must change, put aside as useless; The dust containing capacity of above-mentioned three kinds of filtering materials is limited simultaneously; Generally when dust containing capacity reaches the twice of its initial resistance, just must change, can not re-use.The factory that this has relatively high expectations for lustration class is great cost consumption like clean air-conditioning systems such as food production factory, bio-pharmaceuticals factory, high-end electronic product factory, hospital operating room, ICU zones.
In recent years, effectively the research and development of air filting material is rapid.Air filting material tends to pursue high filter efficiency, but with regard to the prior art level, air filter efficiency is high more, and the pressure drop of air filting material is big more, and the loss of pressure drop does not have effective solution.So how effectively solving the technical problems that need a large amount of replacing filters in the prior art is technological innovation pursuits of domestic and international clean industry field Gonna breakthrough.
At present, first-elected in the world melt-blowing nonwoven (static nonwoven) is as the optimal material of air cleaner electret.The production technology of melt-blowing nonwoven is exactly that the fluoropolymer resin raw material gets into extruder; The polymer that obtains after extruding is dissolved; Ejection forms diameter 2-5mm fiber through spinneret, and through the stretching of two strands of high-speed air flows, the polymer fiber of ejection drops on and forms fleece on the gatherer; Melt-blowing nonwoven is because fiber is very thin, and surface area is very big.Therefore, be used as outstanding air filtration modulator material always.The melt-blowing nonwoven of domestic main employing at present is a polypropylene fibre.
Letting melt-blowing nonwoven become electret generally is to adopt the electrostatic charging method.The electrostatic charging technology that each manufacturing firm adopts is not quite similar.What employing was more at present is the corona discharge method of biased high current charges method, low-voltage, and the electric charge of ionization is embedded in the fiber under aerodynamic effect, forms the severe electret of static.
Research shows, adopts melt-blown non-woven fiber electret air filtering material material, and its electrostatic effect is most important; Increase when specific filtration resistance speed; Make particle movement speed up, attraction that electric charge produced or induction force on the fabric strip weaken relatively, and promptly electric-field intensity dies down relatively; The Coulomb force diminishes the particle movement track near the air-flow streamline to the effect of particulate, causes the severe deposition of its static to descend.Therefrom be not difficult to find out; Because they are to rely on to have more electrostatic charge; Thereby make that the synthetic filter mechanism of air filting material is very complicated; Research also shows, the filter efficiency of fabric filter with dust risen gradually, and static non-woven fabric electret filter to be sedimentation and filtration efficient along with dust descend gradually.
Summary of the invention
The object of the invention is exactly in order to overcome the technological deficiency that existing air filter filtration mechanism is complicated, filter efficiency is poor, the filtering material loss is high, provide a kind of with electret formula polypropylene thermoplastic rod electrostatic precipitation filter application in the air cleaning unit of central air-conditioning ventilating system and clean air-conditioning system.
The present invention is achieved in that
The present invention provides a kind of electret formula polypropylene thermoplastic rod electrostatic precipitation filter, comprises the polyurethane foam layer that is provided with perforate, latticed both positive and negative polarity polypropylene thermoplastic rod electrostatic generator, the metal grill protective layer of the metal grill protective layer that is arranged in order in a framework and the framework, latticed both positive and negative polarity polypropylene thermoplastic rod electrostatic generator, band negative pole electrostatic property.The metal grill protective layer can be limited in filter course within the external frame, simultaneously a plane that can increase electrostatic efficiency can be provided.
Technical scheme of the present invention can be done following optimization:
Said latticed both positive and negative polarity polypropylene thermoplastic rod electrostatic generator comprises long-pending thing layer of latticed anodal polypropylene static and the long-pending thing layer of latticed negative pole polypropylene static.Wherein, the long-pending thing layer of latticed anodal polypropylene static is at the out-of-date friction generates positive electricity electric charge that receives of air communication, and the long-pending thing layer of latticed negative pole polypropylene static is at the out-of-date friction generates negative electricity electric charge that receives of air communication.
The polypropylene thermoplastic bar construction of having positive and negative electrode stationed that the long-pending thing layer of said latticed positive and negative electrode polypropylene static interweaves by longitude and latitude; Wherein, The polypropylene thermoplastic rod of warp direction is with multiply electret formula polypropylene thermoplastic bar construction, and the polypropylene thermoplastic torch of weft direction then constitutes with sub-thread electret formula polypropylene thermoplastic torch.
The sub-thread diameter of said electret formula polypropylene thermoplastic rod is 0.2mm.
The thermoplastic rod of said warp direction is made up of the sub-thread thermoplastic torch more than 3 strands side by side, and with 10mm with interior distance separately, weft direction then constitutes with sub-thread sub-thread thermoplastic torch, and to be not more than the 0.2mm distance separately.
The thickness of said polyurethane foam layer is 15mm-20mm.This open-cell material is at the out-of-date generation static of air communication; And this static can improve the positive-negative polarity between the long-pending thing layer of latticed positive and negative electrode polypropylene static; And isolation through relative thickness; Foam layer can prevent that the charging zone between the long-pending thing layer of latticed positive and negative electrode polypropylene static from having dust accretions, thereby promotes the ability that filter holds dust.Except electro static filtering character, filter used when the foam layer of perforate also can be used as traditional bump, and, can break up the dust in the air-flow, make it make level and move both vertically, thereby improve the efficient of electrode layer.
The diameter of the metal wire of said metal grill protective layer is 0.8-1mm.
