Bag filter is a kind of multi-purpose filtration equipment with novel and reasonable structure, good sealing performance, strong flow capacity, easy operation and many other advantages. It has a wide range of applications and strong adaptability.
Structure and working principle
bag filter is a pressure filter device, mainly composed of filter cylinder, filter cylinder cover, quick-opening mechanism, stainless steel filter bag reinforcement net and other main components. 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 by the liquid infiltrating the filter bag of the required fineness grade, and the impurity particles are intercepted by the filter bag. The machine is very convenient to replace the filter bag, and there is basically no material consumption for filtration.

Product Category
Bag filters mainly include the following categories: single-bag filters, multi-bag filters, rocker bag filters, high-precision bag filters, etc. For example, the multi-bag rocker filter produced by Xinxiang Aida Machinery Equipment Co., Ltd. The filter accuracy is in the range of 1-10 microns.
The main advantage
The possibility of side leakage of the filter bag is small, which effectively guarantees the filter quality.
Bag filter can carry larger working pressure, small pressure loss, low operating cost and obvious energy saving effect.
The filtration precision of the filter bag has been continuously improved, and it has now reached 0.5μm.
The bag filter has large processing capacity, small volume and large dirt holding capacity.
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.
The filter bag can be reused after cleaning, saving cost.
The bag filter has a wide range of applications, flexible use and various installation methods.
Specification
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 diameter of the inlet and outlet flanges is φ40-450MM, and the maximum flow rate of a single machine is 90-1000m3/h. Quick-opening design is available, and 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 use. The multi-bag filter is difficult to operate by one worker due to its large volume and heavy top cover. Adding a rocker device to this filter can reduce labor costs and meet customer requirements
Bag filter application
Food and beverage: sugar filtration, spice filtration, tea beverage filtration, alcohol, mineral water, beer, etc.;
Water treatment: system purification in cooling devices, oil field water injection and well-free filtration, power plant condensate water purification and ion exchange resin recovery;
Chemicals: catalyst recovery carbon removal ink and filter aid;
Adhesive: In addition to acrylic adhesive gel, in addition to PVC coagulation hot melt polymer filtration;
Lubricating oil: filter the lubricating oil before packaging, and filter the lubricating oil in addition to the filter agent;
Case
One of our clients from Turkey is in food industry. Their plant produces beer. Before they are using a type of filter from a local manufacturer. And the water treated from filter is not qualified. They consulted us for recommend. According to their operation situation, our engineer proposed bag filter with model of ADB-3, equipped with 3 filter bag of 2#. Size DN100, body dimension Φ510*1530*3mm, pressure 1.0Mpa, SS316 material with quick open lug. They ordered 2 sets. After installed on their system, It proved that the filter works well, meeting their standard. We agreed to repeat business in future.
