基于FLUENT数值模拟的防爆门快速复位控制系统

A Rapid Reset Control System for Explosion-proof Door Based on FLUENT Numerical Simulation

矿井灾变时,立风井的密封复位速度十分关键,为了解决相关的技术难题,对煤矿中立风井的快速复位的技术以及备用的防爆门进行了研究。对备用的防爆门进行了抗冲击和变形模拟实验,结果显示为:现有的与所设计的两个防爆门系统是相互独立的,煤矿井下一旦发生了瓦斯爆炸,该系统可以最快速度封闭风井井口,起到与防爆门一样的功能,既能通风又能反风,备用的防爆门系统有可活动的风门,风门可以在矿井再次或者多次发生爆炸时自动复位或打开,在矿井发生事故时可保证空气的正常流通。

In order to solve the related technical problems, the technology of quick reset of mine neutral air well and the backup explosion-proof door are studied in order to solve the related technical problems.The simulation results of shock resistance and deformation of the spare blast proof door show that the existing and the designed two blast proof door systems are independent of each other, once the gas explosion occurs in the underground coal mine,The system can close the air well as fast as possible, and play the same function as the explosion-proof door.Can both ventilation and backwind, the backup blast door system has a movable air door, sealing doors can be mine again or multiple explosions in the event of automatic The reduction or opening of the mine can ensure the normal circulation of the air when an accident occurs in a mine.
