Why the Air Filter resistance is very practical
With the increasing environmental pollution and the strengthening of people's environmental awareness, air quality has become one of the focus of attention. It is now recognized that air filtration systems not only protect machinery but also protect people. Therefore, the scope of application of Air Filters more and more widely, including the pharmaceutical industry, cosmetics production workshop, hospitals, food processing industry, clean room, air conditioners, HAVC system.
But the total cost of clean air system is high, the operating costs of clean equipment accounted for a large proportion of the total cost, for example, the general electronics factory clean room using axial fan shaft air circulation form, if the unit cycle wind energy consumption by 0.236w M3 / h) calculation, electricity costs 0.6 yuan, only about 5 million yuan per year to run electricity.
So high operating costs have become an obstacle to promote the use of Air Filters. Can reduce the energy consumption of equipment, that is, to ensure a certain filtration efficiency under the premise of reducing the resistance of Air Filters, is the key to solve the problem. Reduce the energy consumption of clean equipment has become one of the current direction of air clean research. Air Filter structure optimization, is an effective means to achieve this goal.
In recent decades, Air Filter structure design has made significant progress, the most important of which is the development of non-partition filter. No separator Air Filter is a new type of high efficiency filter developed in the 1970s, not only eliminates the danger of bad media in the partition plate. But also effectively increase the filtration area, improve the filtration efficiency, and reduce the airflow resistance, thereby reducing the energy consumption.
Non-partition high efficiency filter design starting point is to reduce the structural resistance, and bag structure of the filter structure resistance is relatively small. The filter structure similar to the YGG type low resistance sub-efficient filter for the filter bag filter, but the experiment is expected to get the optimal filter bag diameter is much larger than 20mm, and no support the role of the filter flap, thereby increasing Flow channel area, reduce resistance. Therefore, the Air Filter has a potential market prospects, the test test analysis both theoretical and practical economic significance.
With the air pollution problem more and more serious, junior high school Air Filter in the industrial application is also more and more common. However, if the installation is unreasonable, may cause the primary Air Filter filter efficiency. Here are some precautions when installing:
1, the installation of Air Filter, be sure to follow the instructions to operate, the filter frame on the arrow on behalf of the direction of the air, in the installation, be sure to ensure that the arrow and the actual direction of the same air, if the need for vertical installation, then its The internal filter paper folds should be oriented perpendicular to the ground. In the installation, it should make the galvanized mesh surface in the back of the outlet direction, and the bag Air Filter, the bag should be the length of the direction perpendicular to the ground.
2, if the Air Filter needs to be installed in the clean room, try not to use wood frame version, to prevent the breeding of bacteria, thus affecting the indoor air quality. The best choice of metal frame filter, and to have a good anti-corrosion ability. In the installation process, we must pay attention to the Air Filter and the seal between the frame, must ensure that tight, no leakage, so as to protect the equipment filtering effect. If the ambient temperature is high, use a high temperature Air Filter.
3, the Air Filter before installation, do not open the bag or packaging film, so as to avoid damage to the equipment, and marked by the direction of the box storage. In the handling process, to do gently, to avoid the shock and collision, so that the Air Filter damage. For high efficiency filters, the installation direction of the pipe must be correct; in addition, the corrugated plate combination filter in the vertical installation, the corrugated board must be perpendicular to the ground.
