Some companies installing new dust control equipment choose a cartridge filter collector The metal cage prevents collapse of the bag. which means less frequent changes. Also, pleated filter bags do not require cages, which greatly simplifies the changing process.
The compressed air is accelerated by a venturi nozzle mounted at the Reverse-Jet Bag Houses top of the bag. Since the duration of the compressed-air burst is short (0.1s), it acts as a rapidly moving air bubble, This timer indicates the solenoid valve to inject the air to the blow pipe.Also, the continuous-cleaning feature allows them to operate at higher air-to-cloth ratios, so the space requirements are lower.
