Bag filter is a wide range of applications, adaptable multi-purpose filter equipment. In particular, the leakage rate of the filter bag side leakage is small, the bag filter structure is novel and reasonable, the sealing is good, the circulation ability is strong, the operation is simple and so on. Can accurately ensure the accuracy of filtration, and can quickly replace the filter bag, the basic filter without material consumption, making the operating costs. Bag filter for alcohol, beverages, food, viscose, resin dyes, ink and oil products, chemicals and other industries liquid fine filter. Filter fineness by the filter bag to ensure that the middle without sampling re-inspection, and supporting the pump installed in the mobile cart, can be moved to any production line to filter.
Bag filter is a kind of pressure filter device, mainly filter tube, filter cover and quick opening mechanism, stainless steel filter bag reinforced mesh and other major components, the filtrate from the filter shell side of the inlet pipe into the filter bag, The filter bag itself is the device in the strengthening of the basket, the liquid penetration of the required level of grade filter bag that can get a qualified filtrate, impurity particles blocked by the filter bag. The machine is easy to replace the filter bag, the basic filter without material consumption.
In terms of filtration, regardless of its equipment in the form of its bag filter filter mechanism is nothing more than two:
1, on the surface of the filter medium at this time the filter medium is very thin, solid particles were trapped in the filter media surface to form a filter and the filtrate through the dielectric layer pores were separated.
2, the filter medium has a certain thickness, solid particles are mainly trapped in the filter medium.
These two filtration mechanisms rely on the pressure difference between the two ends of the filter medium to carry out, there is no boundaries between the two, often exist at the same time. The filtration rate is generally related to the pore size of the filter medium, the filtration pressure, the solid concentration of the suspension, the particle size distribution of the solid particles, the compressibility of the solid phase and the suspended colloid. At present, in the environmental protection and chemical industry The solid-liquid separation required is highly accurate and the materials to be treated are often difficult to separate. Requirements filter device structure is simple, accurate and convenient operation, the output of the filtrate as clear as possible, the initial run-time filter running time is short, there is sufficient mechanical strength and stiffness. And requires careful consideration of material chemical composition from the aspects of economic efficiency and quality control and the completion of the entire process in a sealed system. The bag filter is a new type of filter that meets these requirements and is suitable for solid-liquid separation of refractory suspensions.
Bag filter filter mechanism is basically these, but we actually in the filter operation, we have to carry out experimental research, to more clearly grasp the bag filter filter mechanism.
Bag filter technology is compact, small footprint and wide range of filtration accuracy; the same time, the unit area over flow, filter resistance is small, low cost; easy maintenance, fast; complete specifications, diverse materials and a wide range of applications.
Because the filter bag used in the low cost, so the filter system in the event of a clogging phenomenon can sacrifice the bag to protect the expensive coating liquid, can significantly reduce the operating costs of the depot; common top-notch design to filter more Convenient, save a lot of labor costs; filter containers evenly distributed within the flow of the filter bag filter media surface impurities are evenly distributed; In addition, by adding a dedicated magnetic media, can strengthen the adsorption of metal impurities, Service life.
The high efficiency of the filtration system can effectively prevent the migration of the filter bag fiber and ensure the complete mechanical structure and high efficiency filtration performance of the filter bag. Through the modular design, the standard specifications of the basket for all standard size of the filter bag, making the filter bag selection of the versatility has been greatly improved.
