The structure and principle of the bag filter

The bag filter is a separate device separated from the dust -containing gas with a filter medium. Due to less one -time investment and low operating costs, and the separation efficiency is higher than the whirlwind separator, it is widely used in the pharmaceutical industry.

The structure and working principle of the bag filter

The bag filter is a pressure -type filter device, which is mainly composed of the main components such as the filter tube, the filter tube cover and the fast -opening mechanism, and the stainless steel filter bag enhanced network. The filter bag itself is installed in the enhancement of the network basket. The liquid penetration can get a qualified filter fluid through the filter bag that requires fineness. The impurities particles are intercepted by the filter bag. This machine is very convenient to replace the filter bag, and the filter is basically no material consumption.

The bag filter has many advantages such as reasonable structure, good sealing, strong circulation, and simple operation. In particular, the leakage rate of the filter bag is small, which can correctly ensure the filtering accuracy and quickly change the filter bag to reduce the operating cost. The inside and outside surface of the filter is solved by mechanical sandblasting, and it is easy to clean.

The filtering method adopted by the bag filter is the method of the side inlet, which can also adopt the method of the side bottom out of the bottom out. The filtering medium is pressed into or pumped into the bag filter barrel through the pressure in the pipe. The liquid medium supports the filtering of the filtering bag of the Filter Lan Cheng's filtering by electric polishing, and the changing solid liquid reaches the result of the liquid medium being filtered, respectively.

The structural design of the bag filter is tightened by the four sets of hammer -type ring bolts to block the top cover and the filter tube, so that the filter can withstand high filter pressure and water hammer pressure impact. The bag filter consists of three parts: filter barrel, filter basket, and filter bag. The structure is compact and simple. Essence
