Bag filter structure and working principle:

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. The impurities are intercepted in the filter bag and can be used continuously after replacing the filter bag.
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 flows into the filter bag from the side inlet pipe of the filter housing. 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. This 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 quickly changed, 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 through electro-polishing punching holes, and the changed solid and liquid reach the result of the liquid medium being filtered.
                                                             

Advantages of bag filters:

⑴The bag filter has a compact structure and a reasonable size. Installation and operation are simple, convenient, and occupy a small area.
⑵ The bag filter has high filtration accuracy, suitable for any fine particles or suspended matter, and the filtration range can be from 0.5 to 200 microns.
⑶ The processing flow per unit filtration area is large, the filtration resistance is small, and the filtration efficiency is high. The filtering function of a liquid filter bag is equivalent to 5-10 times that of the filter element, which can greatly reduce the cost; the design flow can meet the requirements of 1~500m3/h, and the cost is low.
⑷ The bag filter has a wide range of uses, which can be used for coarse filtration, intermediate filtration or fine filtration; when the same filtration effect is achieved, compared with the plate and frame fine filter, filter element filter and other equipment, the investment cost is lower and the service life is lower. The advantages of long and low filtration cost.
⑸ High filtration precision, large filtration processing capacity, low cost and high efficiency.
⑹ The liquid bag filter is free of cleaning, and the replacement of the liquid filter bag can be completed within 30 seconds, which is convenient and fast, saving labor and time.
⑺ The liquid bag filter has complete specifications, including low-pressure, side-entry, top-entry, multi-bag, and horizontal.
⑻ Single-bag filters include: Unit 1, Unit 2, Unit 3, Unit 4, Unit 5.
