Self-cleaning air filter is a new type of air filter with automatic dust cleaning function, especially suitable for long-term, continuous air purification of gas equipment in sandstorm prone conditions. Compared with the traditional air filter equipment, the self-cleaning air filter has the characteristics of simple structure, long service life of the filter element and small maintenance workload.
For high-speed equipment such as air compressors, blowers and steam turbines, dust is one of the main reasons that affect the long-term normal operation of the equipment. Dust scaling inside the equipment will affect the airflow movement, destroy the balance of the impeller, cause the shaft vibration of the rotor to exceed the standard, and make the surge curve drift.
First, the characteristics of self-cleaning air filter
In view of this situation, the self-cleaning air filter independently developed by Aitring has the characteristics of high filtration efficiency, large space utilization rate, good energy saving, long service life of filter material, online replacement and so on. Compared with the traditional cloth bag dust collector, it has stronger self-cleaning effect and anti-humidity and anti-freezing ability.
The self-cleaning air filter can be used not only in the foggy and rainy season, but also in the cold freezing weather and dusty desert environment in winter.
Second, self-cleaning air filter structure
The self-cleaning air filter is composed of four parts: the filter cylinder, the self-cleaning system, the pulse back blowing device and the control system. The filter element is mostly the filter cylinder, and the internal filter material is imported or domestic filter paper.
The self-cleaning and reverse blowing system includes self-cleaning nozzle, reverse blowing pipe, Wench tube, air storage cylinder and filter cylinder, etc. The control system includes programmable controller (including PLC), diaphragm solenoid valve, differential pressure transmitter, differential pressure sensor and LCD display and other accessories.
Third, self-cleaning air filter application range
Self-cleaning air filter is not only suitable for all kinds of air separation devices such as air compressors, but also can be used with high-power diesel engines, large air conditioners and all large air volume equipment.
