Application of stainless steel bag filter in environmental protection water treatment
A bag filter is a kind of multi-purpose filtration equipment with novel and reasonable structure, good sealing performance, strong circulation capacity, simple operation, and many other advantages, wide application range, and strong adaptability.
In particular, the probability of side leakage of the filter bag is small, the filter accuracy can be accurately guaranteed, and the filter bag can be replaced quickly, and the filter basically has no material consumption, which reduces the operating cost. It is suitable for liquid fine filtration in paint, viscose, resin dye, ink and oil products, chemicals, and other industries.
The filter fineness is guaranteed by the filter bag, and there is no need to sample and re-inspect in the middle, and can be assembled on a mobile cart with a supporting pump so that it can be moved to any production line for filtering.
The bag filter is a new type of filtering system. The filter bag is supported by a metal mesh basket inside the filter. 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. After replacing the filter bag Can continue to be used. Through the filter bag, under the action of pressure, the original solution is passed through the filter bag, and the pollutants intercepted by the filter bag stay in the filter bag and the filter residue is left in the filter bag’s purpose.
Composition: filter container, support basket, and filter bag. When the bag filter is used to filter liquid, the liquid enters from the side of the lower inlet of the filter container and rushes into the filter bag from the top of the filter bag supporting the mesh basket.
The filter bag expands due to the impact of the liquid and the uniform pressure surface so that the liquid material is The entire inner surface of the filter bag is evenly distributed, and the liquid passing through the filter bag is discharged from the liquid outlet at the bottom of the filter along the wall of the metal supporting mesh basket. The filtered particles and impurities are trapped in the filter bag to complete the filtering process.
Features: The machine is very convenient to replace the filter bag, and the filter basically has no material consumption. The machine is designed as a single filter, a double filter, and can be assembled on a mobile cart with a delivery pump. The filter bag protection net of the filter is made of stainless steel, and the remaining parts are made of carbon steel and stainless steel for users who filter different media.
Scope of application: Suitable for precision filtration of solid and liquid in oils, petrochemicals, pharmaceuticals, pesticides, paints and coatings, food and beverages, chemical fibers, and wastewater. And under normal circumstances, in order to maintain the high efficiency and smoothness of the bag filter and the filtration accuracy and ensure that the downstream liquid is not contaminated, the machine should be shut down after a period of operation, the filter end cover should be opened, the retentate and the filter bag should be taken out together, and the new filter should be replaced. The replacement cycle depends on the actual situation.
Selection: The bag filter is often set after the pressure filter to remove fine particles in the liquid to meet the water intake requirements of the subsequent process. Bag filters are often used as security filters for electrodialysis, ion exchange, reverse osmosis, ultrafiltration, and other devices.
The bag filter has effectively improved the development of my country’s water resources and has also brought a comprehensive treatment of sewage problems, which has further ensured the safety of my country’s ecological environment. It is the best choice for sewage treatment. It uses a filter to directly intercept impurities in the water, remove suspended solids and particulate matter in the water body, reduce turbidity, purify water quality, reduce system dirt, bacteria, algae, rust, etc, to purify water quality and protect other equipment in the system Precision equipment that works normally.
Water enters the body of the bag filter from the water inlet. Due to the intelligent (PLC, PAC) design, the system can automatically identify the degree of impurity deposition and automatically discharge the sewage valve signal. The bag filter is not only exquisite in structure, but also convenient to use, which has made a great contribution to the development of the industry.
