The PGH series of new powder activated carbon filter developed by Wenzhou Dongpu Microporous Filter Co., Ltd. has been certified by provincial science and technology achievements organized by Zhejiang Science and Technology Department in Wenzhou. After the appraisal, the expert believes that the product has been innovated in the special structure of micropores and one-time multi-layer filtration structure design, the highest filtration accuracy of 0.3 microns, reaching the current domestic leading technology level.
Dongpu Company is a technology-oriented enterprise with a history of 30 years and specializing in the development and production of precision microfiltration technology for difficult-to-filter materials. In view of the current shortage of existing powdered activated carbon filtration technology at home and abroad, in the first half of 2004, the company developed a variety of precision microporous filters for different requirements, and successfully applied in the chemical, pharmaceutical and other industries.
The conventional filtration method uses a filter cloth as a medium plate and a filter press, a centrifuge, and the like, and the filtration precision is about 10 micrometers. The three-stage series filtration technology is adopted abroad, and the filtration precision is 10 micrometers, 5 micrometers, and 1 micrometer respectively. In China, filter cloth or wire mesh is used as the filter material, and then the fluff fiber cloth bag is used for terminal filtration. However, it is difficult to ensure that the 1 micron activated carbon particles do not leak, and the microporous membrane with multi-tube filter is used for terminal filtration. It can only reach 0.5 microns. In addition, ceramic microporous sintered tubes or metal microporous sintered tubes are used, but they are difficult to promote due to mechanical strength, acid and alkali resistance, service life, installation and maintenance, and high price.
PGH new high-efficiency activated carbon filter developed by Dongpu Company uses high-molecular polyethylene modified material to make micro-porous sintered tube and its new filtering equipment. The filter material has superior performance and high cost performance. It can seal various acid, alkali and salt. , organic solvent, various inorganic acids and organic acids, temperature resistance up to 100 ° C, no residual material reflux, the highest filtration accuracy of up to 0.3 microns. The product has the characteristics of scientific and reasonable structural design, high degree of automation, high filtration efficiency, low energy consumption, convenient unloading of filter cake and simple regeneration. It is a filter machine with completely independent innovation of filter material and filter structure.
