System of Waste Heat Collection in Long Heat Pipe Based on Internet of Things Structure

为了解决供热管道过长,余热收集效率低、偏差大的问题,利用物联网的特点,设计并实现了基于物联网框架的长距离供热管道余热收集系统,系统将供热管道余热搜集物联网结构划分成感知层、处理层以及应用层。给出了系统中协调器节点、电源电路模块、余热数据采集ADAM-4000系列模块以及余热回收装置的硬件设计方案,以热前沿跟踪模型为基础进行供热管道余热搜集系统的软件设计方案。通过获取供热管道的热前沿参数后,调整供热管道的传热、传质关系式,获取供热管道的余热情况。实验结果表明,该系统能够准确搜集长距离供热管道中的余热,具有较高的应用价值。

In order to solve the heating pipe is too long, waste heat collection efficiency is low, the problem of large devia-tion, advantage of the characteristics of the Internet of things, was designed and implemented based on iot framework oflong distance heat pipe waste heat collection system, the system will heat pipe waste heat collecting iot structure divided in-to perception layer, processing layer and application layer. Given the coordinator node in the system, power supply circuitmodule, the waste heat data acquisition ADAM - 4000 series modules and hardware design scheme of waste heat recoveryunit, based on the thermal cutting edge tracking model for heat pipe waste heat collecting system software design scheme.By getting hot cutting edge parameters of heating pipe, adjust the heating pipe of heat transfer, mass transfer equation, ob-tain the waste heat of heating pipes. The experimental results show that the system can accurately collecting in the recoveryof waste heat in long distance heating pipeline, has higher application value.
