摘要:

为实现煤矿企业清洁能源供热,针对煤矿生产矿井排出的乏风余热,采用目前国际先进的直冷式深焓取热乏风热泵系统供热技术替代传统的锅炉供热,解决我国北方煤矿企业冬季有防冻要求的进风井口供热需求。本文以小保当煤矿矿井乏风余热供热系统项目为例,阐述了直冷式深焓取热乏风热泵系统的间壁式(间接换式)乏风换热、乏风取热机组集尘及结霜原理;采用乏风取热机组清洗除尘和防结霜除霜解决方法,并与天然气锅炉、电锅炉两种供热方案进行对比,分析计算了三种方案的项目投资和系统运行费用,论述了各方案的优势和不足。分析表明,煤矿企业采用矿井乏风余热资源,利用直冷式深焓取热乏风热泵供热系统替代传统锅炉供热,技术可行,且具有更好的经济效益和应用效果。

Abstract:

In order to realize clean energy heating for coal mining enterprises, aiming at the waste heat of exhaust air discharged from coal mining production mines, the current international advanced direct cooling deep enthalpy heat extraction exhaust air heat pump system heating technology is adopted to replace the traditional boiler heating, so as to solve the heating demand of air inlet wellhead with antifreeze requirements for coal mining enterprises in North China in winter. Taking the project of exhaust air and waste heat heating system in xiaobaodang coal mine as an example, this paper expounds the inter wall (indirect exchange) exhaust air heat exchange of direct cooling deep enthalpy heat extraction exhaust air heat pump system, the dust collection and frosting principle of exhaust air heat extraction unit; the solutions of cleaning and dust removal and anti frosting and defrosting of exhaust air heat extraction unit are adopted, and compared with two heating schemes of natural gas boiler and electric boiler. The project investment and system operation cost of the three schemes are analyzed and calculated, and the advantages and disadvantages of each scheme are discussed. Thes analyses show that it is technically feasible for coal mining enterprises to use mine exhaust air waste heat resources and direct cooling deep enthalpy exhaust air heat pump heating system to replace traditional boiler heating, and has better economic benefits and application effects.
