Bag filter is a commonly used filtering equipment, which not only has a novel and reasonable structure, good sealing performance, and strong flow capacity, but also has a simple operation, convenient replacement of filter bags, a wide range of applications, and strong adaptability. In addition to filtration accuracy, we are also concerned about the sealing performance of the filter bag during the use of bag filters. Gano filtration has made technical improvements to the sealing mouth of the bag filter bag, greatly reducing the probability of bag side leakage, accurately ensuring filtration accuracy, and quickly replacing the filter bag. The biggest advantage of bag filters is that there is no residual liquid after filtration, which reduces operating costs. The commonly used fields currently include liquid precision filtration in industries such as paint, adhesives, resin dyes, inks and oil products, chemicals, etc. The filtration accuracy is guaranteed by the filter bag. The Gano bag filter is equipped with high-precision filter bags, which do not require sampling and retesting in the middle. It can be assembled on a mobile cart with a conveying pump for easy movement to any production line for filtration.
Bag filter is a new type of filtration system, which is supported by a metal mesh basket inside the filter. Its working principle is that the liquid flows in from the inlet, flows out from the outlet after being filtered by the filter bag, and impurities are intercepted in the filter bag. After replacing the filter bag, it can continue to be used. Through the filter bag, under the action of pressure, the original solution is passed through the filter bag. The pollutants intercepted by the filter bag are retained in the filter bag, and the filter residue is left in the filter bag. The filtrate flows out along the metal support net basket wall to achieve the purpose of filtration.
The main components of a bag filter are the filter housing, supporting mesh basket, filter bag, and sealing device. When using a bag filter to filter liquids, the inlet method can enter from the side, top, or bottom of the filter, and the filter bag is flushed into the filter bag above the supporting mesh basket. The filter bag is evenly distributed on the inner surface of the entire filter bag due to the impact of the liquid and the uniform pressure surface, and the liquid passing through the filter bag is discharged along the metal supporting mesh basket wall through the outlet at the bottom of the bag filter. The filtered particles and impurities are trapped in the filter bag, completing the filtration process.
Features of bag filter: The machine is very convenient to replace filter bags, and there is basically no material consumption during filtration. This machine is designed as a single filter, a double filter, and can be assembled on a mobile cart with a matching conveying pump. The filter bag protection net can be made of PP, stainless steel, or other alloy steel materials, while other components can be made of PP, carbon steel, stainless steel, or duplex steel, providing users with the option to filter media with different properties.
Scope of application: Suitable for solid-liquid precision filtration in fats, petrochemicals, pharmaceuticals, pesticides, paint coatings, food and beverage, chemical fibers, industrial circulating water, and industrial wastewater. And usually, in order to maintain the efficiency, smoothness, filtration accuracy, and ensure that downstream liquids are not contaminated, the bag filter should be shut down after running for a period of time. Open the end cover of the filter, remove the intercepted material and filter bag together, and replace with a new filter bag. The replacement cycle depends on the actual situation.
