Bag filter is a multi-purpose filtration equipment with a novel structure, small volume, easy and flexible operation, energy saving, high efficiency, airtight operation, and strong applicability. Bag filter is a new type of filtration system. The bag filter is supported by a metal mesh basket inside the filter bag, and the liquid flows in from the inlet. After being filtered by the filter bag, it flows out from the outlet, and impurities are intercepted in the filter bag. After replacing the filter bag, it can continue to be used.
Structure and working principle: Bag filter is a pressure filtration device, mainly composed of filter cylinder body, filter cylinder cover and quick opening mechanism, stainless steel filter bag reinforcement net and other main components. The filtrate flows into the filter bag through the side inlet pipe of the filter machine shell, and the filter bag itself is installed in the reinforcement net basket. The liquid can penetrate through the filter bag with the required fineness level to obtain qualified filtrate, and impurity particles are intercepted by the filter bag. The machine is very convenient for replacing filter bags, and there is basically no material consumption during filtration.
Bag filters have many advantages, such as reasonable construction, good sealing, strong circulation ability, and easy operation. Especially with a low probability of leakage on the side of the filter bag, it can accurately ensure filtration accuracy and quickly replace the filter bag, reducing operating costs. 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 filtration method adopted by bag filters is a side in and side out method, or a side in and 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 supported by the filter bag supported by the filter blue through the electro polishing punching hole, and the changed solid and liquid respectively reach the liquid medium to be filtered.
There are several types of bag filters: single bag filters, multi bag filters, rocker arm bag filters, high-precision bag filters, etc., with filter filtration accuracy ranging from 1 to 10 microns.
Product features: The probability of bag side leakage is low, effectively ensuring filtration quality. Bag filtration can withstand greater working pressure, with less pressure loss, low operating costs, and significant energy-saving effects. The filtration accuracy of the filter bag continues to improve, reaching 0.5 μ M. Bag filtration has a large processing capacity, small volume, and a large capacity for pollutants. Based on the working principle and structure of the bag filter system, it is convenient and fast to replace the filter bags, and the filter machine is self-cleaning, saving labor and time. The filter bag can be reused after cleaning, saving costs. Bag filter has a wide range of applications, flexible use, and diverse installation methods.
