Description

technical field [0001] The invention relates to a waste heat recovery device suitable for various high-temperature flue gases, in particular to a flue gas waste heat recovery device for quick replacement of superconducting heat pipes for recovery and utilization of flue gas waste heat. Background technique [0002] At present, hot flue gas is produced in various industries, especially in metallurgical systems, power plant boilers, domestic boilers, and boilers and kilns in glass, building materials, papermaking, and ceramic industries. High-temperature flue gas is generated, and waste heat energy is greatly wasted. At present, the recovery rate of waste heat in various industries is still very low. To make full use of energy and establish a resource-saving and environment-friendly green enterprise, energy conservation is the direction of development and one of the main ways to reduce energy consumption of enterprises. In order to fully realize the energy saving and consumpti...

AI Technical Summary

Problems solved by technology

Although liquid spray cooling cools down quickly, the heat energy cannot be utilized, and it will also produce mist with secondary pollution, which is not suitable for the principle of energy saving and consumption reduction

Although waste heat boilers and tube-and-tube heat exchangers can recover waste heat, the waste heat recovery effect is poor, the floor space is large, and it is not suitable for small flue gas occasions, etc.
