With the increasing requirements for environmental protection, in order to eliminate the atmospheric pollution caused by particulate matter emitted from industrial production, it is necessary to purify the particulate matter in the exhaust to achieve emission standards.
The technology that removes or captures particulate matter from exhaust gas is called dust removal technology, and the equipment used to achieve this process is called a dust removal device or dust collector. The most widely used one is the bag dust collector.
With the advancement of technology, the dust cleaning technology and bag filter technology of bag dust collectors have been rapidly developed and improved. Therefore, the requirements for the filtration efficiency and service life of PTFE filter membranes are becoming higher and higher, which leads to the PTFE filter Advances in membrane filtration technology.
Features: 1. Surface filtration has small filtration resistance and the dust layer is easy to peel off, solving problems that conventional filtration cannot solve.
2． The pore size is controlled between 0.2~3μm, which can effectively intercept dust.
3． The membrane surface is smooth, no condensation, easy to clean, maintains dust removal efficiency, and greatly enhances service life.
4． The filter material’s long service life, high and low temperature resistance, chemical stability, and non-aging properties make it extremely adaptable to temperature, humidity, and corrosive gases, which is unmatched by current conventional filter materials.
At present, the control of particulate dust in industrial waste gas by bag dust collectors, especially the control of highly active particulate dust generated by high-temperature smelting and fuel combustion, has become increasingly mature technically].
The dust removal efficiency of particulate dust is over 99%, it is not affected by the dust specific resistance, and there is no water pollution problem.
This shows the importance of PTFE filter membrane to bag dust collector.
