An air filter is a device that can obtain clean air up to the standard through the operation of the machine. Air filter is generally a series of operations for different particle size dust particles in the air, such as capture, adsorption. Through a series of operations to improve air quality,Air filterIn addition to adsorbing dust, it can sometimes be used to adsorb odors. This kind of air filter is usually used in biopharmaceuticals, hospitals, airport terminals, human settlements and other places. In general, the use of air filters is quite extensive, such as microelectronics industry, coating industry, food and beverage industry and so on. The air filter is equivalent to a means to achieve the goal of cleanliness.
Air filters have many performance indicators. The first is the filtration accuracy, which refers to the maximum diameter of impurity particles allowed to pass through the equipment. There are many factors that affect the filtration accuracy, but the most important thing is the filter element, so under normal circumstances we can choose different filter elements according to the needs of the following components to make it achieve the corresponding filtration accuracy.
The second is the quantity characteristic, which refers to the relationship curve between the amount of air that can pass through the filter and the pressure drop at both ends of the filter under a certain pressure at the inlet. Therefore, when we use it in practice, we should try our best to choose it in the range where the pressure loss is less than 0.03MPa. For air filters, the most important factors affecting the characteristics of the volume are the body and the filter element.
The water separation effect usually refers to the water separated by the air filter and the ratio of the water content in the air at the air inlet. The most influential water diversion effect is the deflector.
Different dense density metering air filters usually have different filtering effects. Among them, the weight effect indicates the dust concentration, usually expressed in mass concentration (g/m). The counting effect represents the dust-containing density, which is expressed in terms of counting density (pc/L). Sodium flame effect is to sodium chloride solid particles as a source of dust. In general, the concentration of sodium chloride particles measured by photoelectric flame photometer. The sodium flame effect is comparable to the counting effect.
Filter resistance is divided into initial resistance and final resistance. Initial resistance refers to the resistance of the new filter under the rated air volume. Final resistance refers to the resistance when the dust holding capacity of the filter is large enough and the filter material needs to be cleaned or replaced under the rated air volume.
