Bag filter


Bag filterIt is a multi-purpose filtering 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. There are mainly the following types of bag filters: single-bag filters, multi-bag filters, rocker bag filters, high-precision bag filters, etc. The filter accuracy ranges from 1-10 microns.


Structure and working principle: The bag filter is a pressure filter device, which mainly consists of filter cylinder body, filter cylinder cover and quick opening mechanism, stainless steel filter bag reinforcement net and other main components. The filtrate is from the side entrance of the filter housing The tube flows into the filter bag. 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.


Bag filterIt 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 filtering 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 filter 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 into 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 the electro-polishing punching hole, and the changed solid and liquid reach the result of the liquid medium being filtered.


The main advantage:


1. The side leakage rate of the filter bag is small, which effectively guarantees the filtering quality.


2. The bag filter can bear greater working pressure, with small pressure loss, low operating cost and obvious energy saving effect.


3. The filter accuracy of the filter bag has been continuously improved, and it has reached 0.5μm at present.


4. The bag filter has large processing capacity, small volume and large dirt holding capacity.


5. Based on the working principle and structure of the bag filter system, it is convenient and quick to replace the filter bag, and the filter is free of cleaning, saving labor and time.


6. The filter bag can be used repeatedly after cleaning, saving cost.


7.Bag filterIt has a wide range of applications, flexible use and various installation methods.
