Air-conditioning high-efficiency filter filtration principle and effect
Air-conditioning high-efficiency filter filtration principle and effectAir conditioning high-efficiency filters are commonly used in industrial production purification equipment, non-spacer high-efficiency air filters are small in size, light in weight, stable in filtration efficiency, even in air supply, and are widely used in clean plants. They have a cubic structure, and their outer frames are generally made of aluminum alloys, multilayer plate frames, aluminum plate frames, and other materials.Air conditioning high-efficiency filters generally use glass fiber as filter material, glass fiber filter material is high temperature resistant, has structural stability, incineration, and long service life, and is currently one of the more ideal filter materials, with the continuous progress of synthetic fiber technology, there are also some manufacturers use electrostatic polytetrafluoroethylene fiber as a filter material for the high-efficiency air filters without a spacer, it can be foreseen that synthetic fiber is the mainstream direction of development of the filter material in the future. It can be foreseen that synthetic fiber is the mainstream direction of future filter material development. Air conditioning high-efficiency filters use hot melt adhesive to separate the filter elements, which can facilitate mechanized production, while partition high-efficiency air filters are mostly made of kraft paper, offset paper, or aluminum plate as a partition, and when the temperature and humidity change, the role of the partition may be affected, which may even lead to a decrease in the cleanliness of the air in the clean plant, therefore, if the enterprise has high requirements for the cleanliness of the air in the clean plant, it is best to choose the non-compartmental high-efficiency air filter. Therefore, if enterprises have high requirements for clean plant air cleanliness, it is better to choose a non-spacer high-efficiency air filter. Some people think that the filtration principle of high-efficiency air filters is similar to sieve this idea is wrong. Dust particles will change with the airflow, and do irregular Brownian motion, in the process of dust particles in the movement of the filter material will collide in the intermolecular interaction force so that particles stick to the surface of the filter material, several smaller particles will be in the collision with each other, and ultimately the formation of larger dust particles sink to the dust hopper. The use of electrostatic PTFE fiber cartridges without partition high-efficiency air filters can also use electrostatic filtration of dust, although electrostatic action in the filtration only plays a supporting role, but can make the filtration efficiency significantly improved. |
