摘　　要：针对压风机运行过程中产生大量热能导致资源浪费、设备故障等问题,开发一套矿井压风机热能回收自动监控系统。首先阐明矿井压风机热能回收系统基本组成,包括热能回收系统和热能利用系统两部分,并对热能回收自动监控系统的硬件结构进行设计,根据实际监控需求,对热能回收利用监测子系统、压风机自动监测子系统和恒温恒压供水子系统三部分进行软件设计;最后,通过煤矿实际应用表明自动监控系统能够稳定运行,可回收46℃温度的热水量245 t/d,经计算回收总热量达到29427200 k J/d,折合燃煤质量2.43 t/d,大大减少经济成本并提高生产效率。Aiming at the problems of resource waste and equipment failure caused by the large amount of heat energy generated during the operation of pressurised fans,an automatic monitoring system for heat energy recovery of pressurised fans in mines is developed.Firstly,it clarifies the basic composition of the heat energy recovery system of the mine pressure fan,including the heat energy recovery system and the heat energy utilisation system,and designs the hardware structure of the heat energy recovery automatic monitoring system,and according to the actual monitoring requirements,it designs the software for the heat energy recovery and utilisation monitoring sub-system,the automatic monitoring sub-system of the pressure fan,and the constant temperature and constant pressure water supply sub-system;lastly,it shows that the automatic monitoring system can be stably operated and can recover a large amount of heat energy,which can lead to equipment failures.Finally,through the practical application in coal mines,it is shown that the automatic monitoring system can operate stably and recover 245 t/d of hot water at a temperature of 46℃,and the total heat recovered is calculated to be 29,427,200 kJ/d,which is equivalent to the quality of coal combustion of 2.43 t/d,which greatly reduces the economic cost and improves the production efficiency.
