Especially in the traditional industry of animal husbandry, energy consumption is large and environmental pollution is a prominent problem. A large amount of waste heat generated in the breeding process, such as the heat energy emitted by the body temperature of livestock and poultry, the heat in the manure treatment process, etc., are usually not effectively recycled and utilized, resulting in a huge waste of resources. In winter, additional heating is required in the breeding houses, resulting in additional energy loss. In view of this, the utility model provides a waste heat recovery device, which not only helps to improve energy utilization efficiency and reduce production costs, but also reduces greenhouse gas emissions, which is of great significance for promoting the green transformation of the breeding industry. Example

The second centrifugal fan is located below the first centrifugal fan 2. A fresh air outlet 9 is provided above the box body 1. The fresh air outlet 9 is connected to the interior of the breeding house 7 through a second connecting pipe 10. The second centrifugal fan is used to transport external fresh air into the heat exchange core 4 and transport the fresh air after heat exchange from the fresh air outlet 9 to the breeding house 7.

[0026] This waste heat recovery device is installed outside the breeding house 7 and is used to exchange heat with the exhaust gas discharged from the breeding house 7, and the fresh air that has obtained heat is then input into the breeding house 7. When this waste heat recovery device is working, the first centrifugal fan 2 transports the exhaust gas with heat in the breeding house 7 to the heat exchange core 4, and the second centrifugal fan 3 transports the external fresh air into the heat exchange core 4. After the exhaust gas with heat and the fresh air exchange heat, the exhaust gas is discharged from the exhaust gas outlet at the bottom, and the fresh air that has obtained heat is transported to the breeding house 7 through the second pipeline, realizing the heat recovery and utilization of the exhaust gas in the breeding house 7.
