基于PLC一体机的空气压缩机余热回收控制系统方案

Scheme of the Control System of Waste Heat Recovery of Air Compressor Based on PLC Integrated Machine

空气压缩机余热回收是一项高效环保的余热利用技术,它将空气压缩机运行时产生的废热收集用于加热水,将这些热水用于生产和生活,经济效益十分明显.同时进行热交换后,空气压缩机工作温度降低,延长了设备的使用寿命.该方案结合中小型企业的实际情况,采用PLC一体机系统作为控制系统,基本实现了设计成本低、控制可靠、系统维护方便、节能效果明显等几个方面的设计要求.

The recovery of waste heat of air compressor is a high efficient and environmental friendly waste heat utilization technology. It collects the waste heat generated during operation of air compressor for heating water,the hot water is used for production and life,and the economic benefit is obvious. At the same time,the working temperature of air compressor is reduced,and the service life of the equipment is prolonged. In this scheme,combining with the actual situation of small and medium enterprises,and taking the PLC integrated system as the control system,the design requirements of low cost,reliable control,convenient system maintenance,obvious energy saving and so on are basically realized.
