涂布生产线负压立式烘箱的原理及控制

Principle and Control of Negative Pressure Vertical Oven for Coating Production Line

目前热风循环工业烘箱多数属于正压状态下的无组织排放系统,跑冒烟严重,烟气收集难度大。随着国家对重点行业挥发性有机物VOCs排放管控越来越严格的趋势,烟气唯有通过负压状态下的有组织排放才能便于收集进行达标治理,达到国家环保要求。

At present, most of the hot air circulation industrial ovens belong to the non-organized emission system under positive pressure, which causes serious smoke emission and great difficulty in flue gas collection. With the trend of more and more strict emission control of VOCs in key industries, the flue gas can only be collected and controlled by organized emission under negative pressure, which can meet the national environmental protection requirements.
