Abstract

The invention discloses a space dust distribution rule analyzing method of an underground grain channel, and belongs to the technical field of dust distribution rule analyzing inside the grain channel. The technical purpose is to solve the problem that a dust prevention system inside the grain channel cannot be scientifically deployed and controlled since the dust distribution rule inside the underground grain channel cannot be effectively analyzed. The method comprises the steps of firstly, constructing a structure model of the underground grain channel, and selecting dust monitoring sites inthe structure model; conducting analog simulation on the dust flowing situation of the underground grain channel; putting up a test platform, and obtaining original monitoring data of the dust monitoring sites through a senor arranged on the test platform; adopting an Euler-lagrange algorithm to calculate the original monitoring data to obtain fluid flow transporting equations of a continuous phase and particle distribution data of a discrete phase; building a k-allele model according to the fluid flow transporting equations and the particle distribution data of the discrete phase, and calculating grain dust change distribution rule data relevant to temperature and humidity data. The space dust distribution rule analyzing method of the underground grain channel is used for analyzing the dust distribution rule.

Description

technical field [0001] The invention relates to a method for analyzing the spatial dust distribution law of an underground grain road, and belongs to the technical field of dust distribution analysis inside the grain road. Background technique [0002] Dust floating in the air often brings great harm to human life and property. It is not only manifested in the pollution of the atmospheric environment and the impact on human health, but also in the explosion accidents that may occur in a limited space. Dust explosion accidents occur from time to time, and the losses caused cannot be underestimated. [0003] Since the first recorded grain dust explosion occurred in a flour mill in Turin, Italy in 1785, with the development of world industry and the increase of grain production, grain dust explosion has become its companion. [0004] Grain dust explosion refers to the process in which the flame of combustible grain dust burns rapidly spreads in the unburned dust cloud, releas...
