With the development of science and technology, more and more efficient filtration equipment began to appear in our lives, such as activated carbon filters, high efficiency filters, and in the selection of these devices, we often hear useful filter area Word, and a lot of people know that should choose a useful filter area of large equipment, but this is because Shane?
In fact, refers to the actual area of the air through the filter, in addition to a small amount of inefficient filtration equipment, the majority of equipment useful filter area is several times the equipment wind surface, dozens of times or even a hundred times . Because most of the captured dust pollution is concentrated on the top surface of the filtration equipment, the larger the effective filtration area, the more dust the equipment can contain and the longer the service life of the equipment.
And through a series of practice can also prove that a reasonable increase in the effective filter area is the best way to extend the service life of equipment on the same structure and filter media filtering equipment, when the final resistance to determine when the filter area will Add 50%, the service life will also be extended by 70% – 80%, and the original life expectancy increased by about 3 times.
As we all know, the equipment used in the filter more equipment, the higher the natural offer, but the increase must be useful for example, the extension of the use of extension equipment, and useful area increases, the initial resistance will decline, which The energy consumption will decline. It is necessary to select a useful filter area of the device on the user is certainly useful.
Of course, increasing the useful filter area is not random, or according to the structure of equipment and site conditions to consider the possibility of adding, for example, bag filter can add the number and length of its filter bag; the traditional A baffle filter can increase the number of folds of the filter paper by lowering the spacing of the baffles; the more important thing is to design a design that will contain more filter material.
In summary we can get, select a useful filter area of the device on the role of the filter must also be good, but it is not free to be able to carry out, or according to the equipment structure and site conditions to consider the possibility of adding . In the modern use of a variety of efficient equipment, such as activated carbon filters, high efficiency filters, etc., we must be clear in the use of performance to be added after.
