Lange Purification today tells you about the relevant knowledge of the bag filter. Bag filter is a kind of multi-purpose filter equipment with novel structure, small size, simple and flexible operation, energy saving, high efficiency, airtight work and strong applicability. Bag filter is a new type of filtration system. Inside the bag filter, the filter bag is supported by a metal mesh basket. The liquid flows in from the inlet and flows out from the outlet after being filtered by the filter bag. Impurities are intercepted in the filter bag and can be used continuously after replacing the filter bag.
Structure and working principle: The bag filter is a pressure filter device, which mainly consists of a filter cylinder, a filter cylinder cover, a quick opening mechanism, and a stainless steel filter bag reinforcement net. The filtrate comes from the side entrance of the filter housing The tube flows into the filter bag, and the filter bag itself is installed in the reinforced mesh basket. The qualified filtrate can be obtained when the liquid penetrates the filter bag of the required fineness level, and the impurity particles are intercepted by the filter bag. The machine is very convenient to replace the filter bag, and the filter basically has no material consumption.
The bag filter has many advantages such as reasonable structure, good sealing, strong circulation ability, and easy operation. In particular, the probability of side leakage of the filter bag is small, the filter accuracy can be correctly guaranteed, and the filter bag can be changed quickly, which reduces the operating cost. The inner and outer surfaces of the filter are solved by mechanical sandblasting and polishing, which is average and easy to clean.
We know that the filtering method adopted by the bag filter is a side-in-side-out method, or a side-in-bottom-out method. The filtered liquid medium is pressed or drawn into the bag filter barrel through the pressure in the pipeline. , The liquid medium to be filtered is filtered by the filter bag supported by the filter basket supported by the electro-polishing punching hole, and the changed solid and liquid respectively reach the result of the liquid medium being filtered.
Bag filter is divided into: single bag filter, multi-bag filter and sandwich filter. Multi-bag filter, suitable for large flow filtration. From 2 bags to 24 bags, the specifications are complete, the inlet and outlet flange diameter is φ40-450MM, and the maximum flow rate of a single machine is 90-1000m3/h. Can provide quick opening design, filter bag replacement is very convenient. It is also suitable for occasions where you want to replace the filter bag after a long period of time. The multi-bag filter is difficult to operate due to its large size and heavy top cover. The addition of a rocker device to the filter can reduce labor costs and meet customer requirements.
Bag filter is also a kind of air filter, both belong to hepa box filters, you can choose the appropriate bag filter housing sizes and other requirements according to your own needs.
