Abstract
Description
Technical Field

[0002] In industrial production and processing, some fuels will generate a lot of heat after combustion, and part of the heat will be discharged with the airflow, causing heat loss. This heat loss not only causes great energy loss, but may also have a certain impact on the surrounding environment. Therefore, in order to reduce energy loss, improve energy utilization efficiency, and reduce economic costs, it is necessary to conduct a recovery and reuse of this heat. It is necessary to stably recover and store the discharged waste heat. Therefore, it is necessary to use a heat transfer device to conduct heat exchange. However, some traditional heat transfer devices have a relatively simple heat conduction and heat exchange structure. During heat exchange, they often cannot conduct the heat in the hot air flow evenly and stably. After conduction and heat exchange, there is still a large amount of heat remaining in the discharged airflow. The overall heat energy conduction and heat exchange efficiency is not high, there is still a large amount of heat loss, large energy loss, and low recycling rate. Utility Model Content

After entering the first chamber 6, the hot air flow is evenly distributed through multiple fixed pipes 92 and enters the second chamber 7. At this time, the fixed pipe 92 is heated by the hot air flow, and the first solenoid valve 96 is opened. The water in the liquid storage chamber 94 enters the heat exchange chamber 91 and contacts the outer surface of the fixed pipe 92 to perform heat exchange. The first temperature sensor 911 detects the temperature of the water after heat exchange. After the temperature rises, the second solenoid valve 96 is opened. Solenoid valve 99, the water after heat storage enters the heat storage chamber 97 to store heat and energy, thereby continuous heat exchange and heat storage work can be performed, and the airflow entering the second chamber 7 passes through the second temperature sensor 103 on the exhaust pipe 8. When the heat exchange is incomplete, the exhaust gas temperature is still relatively high. The second temperature sensor 103 detects the residual high temperature, and then cooperates with the controller 11 to drive the return flow fan 106 to run, and the airflow is re-delivered into the first chamber 6 through the return pipe 105, and then heat exchange work is performed, thereby improving the heat exchange efficiency.
