The working principle of a single bag filter is to use a filter bag to filter the fluid, removing impurities, particles, and other substances, thereby achieving the purpose of purifying the fluid. In the filtration stage, the fluid enters the interior of the filter housing through the inlet pipe, passes through the filter bag, and the purified fluid flows out from the outlet pipe. When impurities accumulate to a certain extent in the filter bag, it is necessary to replace the filter bag to ensure the filtration effect. Single bag filters are widely used for liquid filtration in fields such as chemical, pharmaceutical, food, beverage, and environmental protection. It can effectively remove harmful substances such as impurities, particles, and microorganisms from fluids, improving product quality and production efficiency.

Single bag filters can be classified according to different needs and working environments, with the following common classification methods:

♦ Side entry bag filter: designed to be compatible with any feeding port connection direction, especially suitable for high temperature, acid and alkali resistant applications.

♦ Top in bag filter: Compared with the side in type, its feed inlet is located at the top of the filter, suitable for different installation requirements.

♦ Stainless steel bag filter: Made of stainless steel material, it has the characteristics of corrosion resistance, high temperature resistance, etc., and is suitable for harsh working environments.

♦ Plastic filter/sandwich insulation filter: Made of plastic material, it has the characteristics of light weight, easy cleaning, etc. At the same time, the sandwich insulation design can maintain stable fluid temperature.

♦ Fluorine lined anti-corrosion filter: The filter is lined with a fluoroplastic layer inside, which has excellent corrosion resistance and is suitable for filtering highly corrosive fluids.

Main structural features of single bag filter:

♦ Filter cylinder body: usually made of metal material, with sufficient strength and rigidity to withstand the pressure and impact force of fluids.

♦ Filter cartridge cover and quick opening mechanism: easy to replace filter bags and clean the inside of the filter, improving work efficiency.

♦ Stainless steel filter bag reinforcement mesh: used to support the filter bag and prevent deformation or breakage during the filtration process.

♦ Import and export pipelines: Connect fluid sources and filters to ensure smooth fluid flow.
