针对目前国内卷烟厂生产车间普遍存在的夏季烟尘大、表冷器积尘不易清洗、排管换热效果差等问题，在调查基础上进行分析，对表冷器结构进行改进，变固定排管为可调排管，并设置滑轨与滑轮；为保证冷冻水均匀分布，设集、分水器。改造后表冷器既便于清洗又便于维护，并能保证车间的温、湿度要求。 Aiming at the problems such as large summer soot in the domestic cigarette factory production workshop, difficult to clean the dust collector in the surface cooler and poor heat exchange in the heat exchanger, the paper analyzes the investigation based on the investigation and improves the structure of the cooler, Adjustable drainage pipe, and set the rails and pulleys; in order to ensure uniform distribution of chilled water, set set, manifold. After the transformation of the surface cooler is easy to clean and easy to maintain, and can guarantee the workshop temperature and humidity requirements.
