矿井回风直接换热加热新风井口防冻应用
Application of mine return air direct heat exchange heating fresh air wellhead anti-freeze
摘要
Abstract
Based on theoretical analysis and engineering application,the application conditions of wall type heat exchange heating for fresh air shaft anti-freeze technology are proposed in order to promote the application of direct heat exchange for fresh air in mine return air.The research shows that when the direct heat exchange of mine return air heating fresh air technology is used in cold areas,it should meet the matching relationship between the grade of mine return air waste heat resources and heating capacity and the anti-freezing heat load of the shaft,and there is a certain heat transfer temperature difference between mine return air and fresh air.In deep cold ⅡB area,it is feasible to mine seasonal heat damage mine return air direct heat exchange to heat fresh air shaft anti-freeze project and has good energy saving and emission reduction benefits.关键词
