大型结构件数控加工厂房的通风空调系统

Ventilation and air conditioning system for large part numerical control machining buildings

针对数控厂房体量大、金属加工液污染源分散的特点,提出了分层空调+周围捕获的方案。分别对重污染机床未隔离和隔离时厂房内的气雾浓度进行了分析计算,其结论验证了污染物的周围捕获效果优于集中捕获。采用分层空调+周围捕获方案能有效地清除厂房内的污染物。

In view of the characteristics of large space and dispersed pollutant sources of metal machining fluid,proposes a ventilation and air conditioning system scheme,i.e.stratified air conditioning plus peripheral collecting.Analyses and calculates the smog concentration in a machining building respectively on the conditions of isolated and non-isolated heavy pollution source machines,and the results prove that the effect of peripheral collecting is superior to that of centralized collecting.The effect of the scheme of stratified air conditioning plus peripheral collecting is satisfactory.
