Description

technical field [0001] The invention relates to the technical field of waste heat recovery, in particular to a high-efficiency heat exchanger for flue gas waste heat recovery. Background technique [0002] A heat exchanger is an energy-saving device that transfers heat between materials between two or more fluids at different temperatures. It transfers heat from a fluid with a higher temperature to a fluid with a lower temperature, so that the fluid temperature reaches the process The specified index is to meet the needs of process conditions, and it is also one of the main equipment to improve energy utilization. In industrial production, a large amount of smoke will be generated, and these smoke will be directly discharged into the air, which will cause air pollution. At the same time The heat contained in the flue gas will also cause waste of resources.

[0002] A heat exchanger is an energy-saving device that transfers heat between materials between two or more fluids at different temperatures. It transfers heat from a fluid with a higher temperature to a fluid with a lower temperature, so that the fluid temperature reaches the process The specified index is to meet the needs of process conditions, and it is also one of the main equipment to improve energy utilization. In industrial production, a large amount of smoke will be generated, and these smoke will be directly discharged into the air, which will cause air pollution. At the same time The heat contained in the flue gas will also cause waste of resources

[0003] In industrial production, due to different working conditions, the heat carried by the flue gas will be different, but the existing flue gas waste heat recovery high-efficiency heat exchanger cannot adjust the work of the heat exchanger in time according to the amount of heat carried by the flue gas Mode and water flow, thereby reducing the effect and efficiency of heat exchange, and causing a part of energy loss and waste, which is very inconvenient to use. Therefore, in view of the above situation, it is urgent to develop a high-efficiency heat exchanger for flue gas waste heat recovery to To overcome the deficiencies in the current practical application
