[0033] Combine the following Figures 1 to 3 The embodiments of the utility model are described.

[0034] The present embodiment relates to a heat energy recovery structure, which has the characteristic of high safety.

[0035] The heat recovery structure of this embodiment includes:

[0036] A box body 1, wherein the box body 1 is provided with a hot air inlet 11, a hot air outlet 12, a heat exchange inlet, and a heat exchange outlet;

[0037] A partition 2, the partition 2 is arranged in the box body 1 and separates the hot air inlet 11 from the hot air outlet 12, and a fin installation port and a valve port are arranged in the middle of the partition 2;

[0038] A heat exchanger 3, wherein the heat exchanger 3 is located at the installation port, and the heat exchanger 3 is located between the heat exchange inlet and the heat exchange outlet;

[0039] A safety valve 4 is provided at the valve port.

[0040] The partition 2 separates the heat exchange flow channel in the box body 1. When the heat energy recovery structure is working, the exhaust gas passes through the hot gas inlet 11, the heat exchanger 3, and the hot gas outlet 12 in sequence. When the hot gas flows through the heat exchanger 3, it exchanges heat with the heat exchanger 3, and the heat exchange medium flows out of the box body 1 through the heat exchange inlet, the heat exchanger 3, and the heat exchange outlet, providing the heat in the exhaust gas to the outside, thereby realizing heat energy recovery and reducing energy consumption; when cleaning the heat exchanger 3, the safety valve 4 is opened to increase the flow area of ​​the hot gas inlet 11 and the hot gas outlet 12, so as to ensure the safety of the use of the heat energy recovery structure.

[0041] In this embodiment, the installation port is located at the lower part of the partition 2, and the heat exchanger 3 covers the heat exchange inlet, the installation port and the heat exchange outlet. A heat exchange channel is formed in the heat exchanger 3, and the two ends of the heat exchange channel are respectively connected to the heat exchange inlet and the heat exchange outlet. The installation port is set at the lower end of the heat exchanger 3. When the heat exchanger 3 needs to be cleaned, the heat exchanger 3 can be soaked with a small amount of water to reduce water consumption. The heat exchanger 3 covers the heat exchange inlet, the installation port and the heat exchange outlet at the same time, which can increase the overall size of the heat exchanger 3, increase the heat exchange between the external heat exchange medium and the exhaust gas, and improve the heat recovery efficiency. At the same time, the heat exchange inlet, the installation port and the heat exchange outlet covered by the heat exchanger 3 can simplify the heat recovery structure.

[0042] Furthermore, the safety valve 4 is an electric valve. The safety valve 4 is an electric valve, which can be opened and closed by electric control, and the opening and closing of the safety valve 4 is more convenient.

[0043] In order to improve the convenience of cleaning the box body 1, a spray pipe 51 is provided above the heat exchanger 3. The spray pipe 51 is fixedly connected to the box body 1, and one end of the spray pipe 51 passes through the box body 1 to be connected to an external water pipe.

[0044] A drain pipe 52 is provided at the bottom of the box body 1, and a drain valve is provided on the drain pipe 52. The drain valve is provided on the drain pipe 52, and the water can be drained conveniently and thoroughly after the heat exchanger 3 is cleaned.

[0045] In order to reduce water consumption, the heat energy recovery structure further includes a water pump 53 and a water tank 54. The drain pipe 52 is connected to the water tank 54, the input end of the water pump 53 is connected to the water tank 54, and the output end of the water pump 53 is connected to the spray pipe 51. When cleaning is required, the water pump 53 pumps the water in the water tank 54 to the spray pipe 51, and the heat exchanger 3 is sprayed and cleaned through the spray pipe 51. After that, the drain valve is opened, and the water is returned to the water tank 54 through the drain pipe 52 at the bottom of the box body 1, so as to realize the circulation of cleaning water and save water.

[0046] In order to prevent the water level from being too high, an overflow pipe 55 is further provided in the box body 1, and the overflow pipe 55 is located between the heat exchanger 3 and the safety valve 4 in the height direction. After the overflow pipe 55 is configured, the water level in the box body 1 is discharged when it exceeds the overflow pipe 55, which is helpful to prevent accidents caused by excessive water level.

[0047] In order to quickly dry the heat exchanger 3, a blow pipe 6 is provided in the box 1, and a trachea valve is provided on the blow pipe 6. After cleaning the heat exchanger 3, the trachea valve is opened and the blow pipe 6 is ventilated to blow air into the heat exchanger 3 to quickly dry the heat exchanger 3.

[0048] When the heat recovery structure of the present disclosure is working, the exhaust gas enters the box body 1 from the hot gas inlet 11, then flows through the heat exchanger 3 through the flow channel separated by the partition 2, and then is discharged from the box body 1 from the hot gas outlet 12. At the same time, a heat exchange flow channel is provided on the heat exchanger 3, and the two ends of the heat exchanger 3 extend outward to the heat exchange inlet and the heat exchange outlet respectively, so that the heat exchange medium exchanges heat through the heat exchange flow channel. In this embodiment, the heat exchange medium is air, and the air is driven by the fan to enter the channel.

[0049] When the heat recovery structure needs to be cleaned, the water inlet valve of the spray pipe 51 is opened, and the water pump 53 pumps water from the water tank 54 to the spray pipe 51 to flush the heat exchanger 3 through the spray pipe 51. The heat exchanger 3 is a fin heat exchanger 3 in this embodiment.

[0050] When drainage is required, the drainage valve is opened, and water flows out of the drainage pipe 52 and flows back into the water tank 54 .

[0051] In the process of cleaning the fin heat exchanger 3 by the spray pipe 51, especially when the fin heat exchanger 3 is soaked and cleaned, the water will greatly reduce the size of the opening on the heat exchanger 3, and when the flow rate of waste entering the box 1 remains unchanged, it will easily cause the pressure in the box 1 to increase, causing certain dangers. At this time, the safety valve 4 on the partition 2 is opened, and the exhaust gas can flow directly out from the hot gas outlet 12 through the safety valve 4, preventing the exhaust gas in the box 1 from accumulating and continuously increasing the pressure, thereby improving the safety of the use of the heat recovery structure.

[0052] The preferred implementation modes of the present invention are specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of the present invention.
