Analysis Of Xilinhaote Belt Dusting Removal System And Dust Explosion Hazard

Since the operation of Coal Preparation Plant in Datang Xilinhaote, the dustpollution from Coal preparation plant have got very serious.It is because of thenon-hydrophilic and fragility of the raw coal, the complexity of the equipment andproduction technology process, and its irrational dust control equipment.Dustconcentration is between20~505mg/m3, which is not only caused safety problems ofproduction, but also be harm to the health of production management personnel. Themanagement of the environment constraints the management elements at the same time,reducing the level of coal preparation plant managementThe distribution of dust source in the coal preparation plant is provened, by doingthe dust source census to the main position of coal preparation plant. Through reprintand whereabouts at the loading point at the same time, the dual role reproduced in theFumo flat bag filter negative pressure and bow to divert role to eliminate the beltconveyor loading point and the coal chute at the transshipment point positivepressure,the effect of dust is very ideal. Seal the reprint points and the dust particles will notescape. By using this design, the c dust oncentration meets the national standard. Afterusing vacuum seal dust removal system, the dust concentration of sealing system willgreatly increase, possible exists dust hazard. Based on the above all, do explosion riskanalysis of the dust seal system.It provides guidance for Datang Xilinhaote mining in dust control in coalpreparation plant by the study of the theory and technology. Form the new technologieswith innovative open pit coal preparation plant reproduced point system dust control andgovernance, the technological creates economic benefits to Coal Preparation Plant inDatang Xilinhaote Mining and it has higher application value.
