| Since ancient times, coal energy in our nation’s energy occupies a very important role,becoming indispensable to many basic energy. Although it is now gradually being developeda lot of new sources of energy, but coal energy since energy plays an important role. And inthe development in the industries of the future, remains inseparable from supporting coalenergy. With the expansion of coal production, mining depth increases, mining technologyincreases, frequent spontaneous fire of coal became a serious threat to coal miners ’ lives andproperty, seriously affect the development of coal Enterprise barrier.This paper on the basis of previous research on steam-Sol resistance of fire equipmentdid try something new. Through the realization of blocking liquid atomizing nozzleatomization for automobile and Sol. Theoretical analysis of this paper on the basis of a largenumber of tests to select more suitable for steam Sol fire precision ST-5atomizing nozzledevice and ultrasonic atomizing nozzles SUN-PN2. Select jet of blocking solution forautomatic Proportioning, through a significant proportion of theoretical calculations todetermine the Jet pressure is1.0MPa. Traffic monitoring using Vortex flowmeters. Achieveatomization of200Kg resistance of liquid per hour subject to installation of atomizing nozzledetermines the number and installation method. Design of atomized body diameter700mm,3mm thick iron cylinder, a cylinder tapered at both ends. Inlet diameter of100mm, exportdiameter is60mm. Papers by fluent simulations on the entire gas appliance Sol optimizesparameters such as pressure and atomization. Finally the whole steam coal spontaneouscombustion by Sol retarders designed application technology of fire prevention installations.This paper for coal spontaneous combustion in steam-Sol and resistance devices raisednew design ideas, for steam coal spontaneous combustion by Sol and resistance study on thefire safety installations of a certain degree of significance. |
