Power Filter
Use in the dust removal or desulfurization of the new unit, this unit can control the temperature to solve the dust removal equipment due to aging system caused by the increase in oxygen content of the problem; and has good corrosion resistance, can be in the Low oxygen content in the use of conditions.
(1) filter model design: the measured flow field parameters as the boundary conditions, the use of CFD technology for different diameter fiber layered combination of simulation optimization. The results show that the fiber filling density in the depth of filtration has little effect on the packing density of 19-30%, and the fineness is obviously increased by 1.1-2.2dtex ladder.
(2) fiber application technology: the use of 2.2-1.1dtex * 51mm PPS / PTFE fiber to form the bottom layer, the dust layer gradient (filling density of 20%); enamel layer surface layer of dense layer with its formation density gradient (fineness unchanged ), The packing density of 50%; the fabric is preferably PTFE filament (130g / m2); gradient structure filter filtration efficiency of 99.95%, developed by our company`s ultra-fine layer gradient structure filter has won the provincial high-tech Products, the Ministry of Science and Technology Innovation Fund project, and successfully applied to the field of five power dust, to achieve a clean emissions.
(3) grading high-speed high-density acupuncture: the use of high-density graded acupuncture combined process, not only to promote the formation of high dust filter dust density of high porosity dense layer, and reduce the processing of the fabric damage; By 1000N, weft 1500N, PM2.5μm fine dust filtration efficiency of nearly 95%.
(4) PTFE composite emulsion infiltration treatment: the study of PPS and PTFE fiber performance and coal-fired power plant specific environmental parameters (high temperature, nitrogen oxides, sulfur oxides, etc.), the development of special filter surface enhancer (containing PTFE emulsion), Not only improve the effective increase in its high temperature, corrosion resistance, easy cleaning performance, running resistance reduced by about 20%, PM2.5 filtration efficiency of 95%.
(5) acupuncture high temperature hot melt coating process: Our company filter bag production process using German imports of high temperature hot melt coating equipment for the bag suture needle needle high temperature coating, which has good temperature resistance, Acid and alkali, can effectively adapt to the operating conditions, at the same time, the film has a high degree of sealing performance, can reduce the fine dust through the pinhole, side seam direct discharge, reduce the concentration of fine dust emissions, to achieve clean emission requirements
Note: The various parameters reflect the product performance indicators, according to the conditions of a reasonable choice of filter media.
Appendix: A variety of parameters that reflect the performance of products, the modern filtration has been prepared according to the specific working conditions.
