The bag filter is an early type of filtration equipment. Now it has become one of the filtration equipment widely used in the industrial sector. The filtration mechanism of the bag filter is that when gas containing dust (or solid particles) passes through the filter material layer, only the gas is allowed to pass through, while the dust is blocked on the surface of the filter material. The reason for this retention is the interaction of several mechanisms such as diffusion, hooking, inertia, screening, and gravity.
There are many varieties of dust collector bag materials. Bags made of various materials have different uses in dust removal equipment and are suitable for different working conditions. The characteristics are different. Polyester needle felt, nylon filter bag, Metas, polypropylene filter bag, PPS filter bag, P84 filter bag, PTFE filter bag. The material of the filter bag directly determines various performance parameters of the bag dust collector, such as specifications of dust removal equipment, dust removal efficiency, emission concentration, operating resistance, service life and other indicators. Therefore, the correct and appropriate selection of filter bags is very important. Among them, polytetrafluoroethylene filter bag membrane is a very good choice. Polytetrafluoroethylene (PTFE), also known as Teflon, is stretched into a strong microporous material with a pore size of 0.1 μm to 2.0 μm and a porosity of greater than 80%. It has excellent chemical corrosion resistance and can be used in sulfuric acid. , sodium hydroxide and uranium pentafluoride, a strong corrosive in the atomic industry, will not corrode, and can withstand cold and heat. It can be used for a long time at -200℃~250℃, and has good electrical insulation and smooth surface. characteristic. Polytetrafluoroethylene filter bag membrane is often treated with coating or acupuncture techniques to improve dust removal efficiency and extend service life.
It is easy for dust to enter the interior of ordinary filter materials during use, and more and more dust accumulates until the pores are blocked, making it impossible to continue using it. With the use of polytetrafluoroethylene filter bag membrane, the filtered dust is easily removed from the membrane surface, the cleaning effect is good, the cycle is long, and the cleaning pressure intensity used is low, thereby increasing the service life of the filter material and reducing the product’s Operating costs
is the manufacturer that produces polytetrafluoroethylene filter bag membrane. PTFE membrane has low surface tension, non-stick and water resistance. , with low surface energy and good non-adhesive properties, it is easy to remove the dust accumulated on the surface. It can restore its performance by washing with water, achieve reuse, and greatly extend its service life. Surface filtration mechanism, dust can be easily removed through mechanical vibration.
