Xilinhaote Open Pit Coal Conveying System Of A Coal Conveying System Blanking Tube Bag Dust Removal Technology Research

Dust removal system with bag filter and sealed guide chute, based on the principle of pressure relief dust, can effectively curb high pressure and induced merry spray dust problem which is one of the most difficult governance problem of coal conveying system. This way of dust removal can be widely used in the coal conveying belt of dust prevention in all kinds of industrial and mining enterprises. At present, the installed theory designing gist of bag dust removal system is majority by means of pipe network calculation formula of experience, this kind of method to calculate is rough, and not exactly guide field engineering and technical personnel to determine the dust control schemes. Based on this, it establishes dust diffusion of two phase flow model of gas-solid, realizes to optimize and select the technological parameters of bag-type dust collector of coal conveying system, it is used to effectively and efficiently guide field dust prevention engineering of coal conveying system.Based on the above, this researching topic will set up gas-solid two phase flow mathematical model based on the induction wind flow mechanism, we will use the method of combining the numerical calculation, field measurement and the industrial experiment in the XIL's mine coal conveying system, for the most representative removal dust technology parameter optimization and selection of blanking tube, finally determine the optimum dust removal technology parameters, the researching topic involving the theory and numerical simulation method has referenced significance for the dust prevention mechanism of the coal conveying and coal storage system of coal mining enterprises.
