Description
技术领域 technical field
本发明涉及一种球直异形玻璃管低温余热回收装置，属于节能减排应用技术领域。 The invention relates to a low-temperature waste heat recovery device for spherical straight special-shaped glass tubes, and belongs to the technical field of energy-saving and emission-reduction applications.
背景技术 Background technique
随着经济的发展,能源需求紧张的问题日益突出,节约能源、降低能耗愈显重要。针对当前低温余热回收利用率较低,开发低温余热回收产品,拓展低温余热的领域是当前节能减排工作中亟待解决的问题。换热器就是用来实现上述热量交换与传递的设备，通过各种设备使热量从温度较高的流体传递给温度较低的流体，以满足生产工艺的需要。然而余热回收设备中的废烟气中往往含有二氧化硫等成分，遇到蒸汽或水分会形成亚硫酸物质对管板和焊缝产生腐蚀，造成管板或焊缝处的渗漏现象，严重影响企业的连续化生产要求；同时传统的换热装置还存在着许多缺点，如普通金属换热器具有易腐蚀、传热系数受污垢层厚度变化而变化等缺陷，用贵、稀有金属材料制成的换热器因其价格昂贵难以推广应用。 With the development of economy, the problem of tense energy demand is becoming more and more prominent, so it is more and more important to save energy and reduce energy consumption. In view of the low utilization rate of low-temperature waste heat recovery, developing low-temperature waste heat recovery products and expanding the field of low-temperature waste heat are urgent problems to be solved in the current energy-saving and emission-reduction work. The heat exchanger is the equipment used to realize the above-mentioned heat exchange and transfer. Through various equipment, the heat is transferred from the fluid with a higher temperature to the fluid with a lower temperature to meet the needs of the production process. However, the waste flue gas in the waste heat recovery equipment often contains sulfur dioxide and other components. When encountering steam or moisture, it will form sulfurous acid substances, which will corrode the tube sheets and welds, resulting in leakage at the tube sheets or welds, seriously affecting the enterprise. Continuous production requirements; At the same time, there are still many shortcomings in traditional heat exchange devices, such as common metal heat exchangers are easy to corrode, and the heat transfer coefficient is changed by the thickness of the dirt layer. Heat exchangers are difficult to popularize and apply because of their high price.
