Description

[0002] Thermal energy recycling is the process of recycling and utilizing waste heat generated in industrial and daily life processes through various technical means to improve energy efficiency and reduce environmental pollution. During the industrial production process, a large amount of heat energy is discharged into the environment in the form of waste gas, wastewater, etc., causing energy waste and environmental pollution.

[0003] Among them, in the rice production process, a drying tank is needed to dry the rice. A large amount of steam will be generated in the drying process. These steam can be effectively recovered and utilized by installing a waste heat recovery device. The common waste heat recovery method is: the steam is introduced into the spiral tube, and the heat in the steam is exchanged with the cold water in the water tank through the spiral tube, and then the cold water is heated and reused.

[0047] Furthermore, the fixed disk 31 is processed into a circle, and a threaded hole is processed on the outer periphery of the fixed disk 31. The transmission shaft 32 rotates in the fixed disk 31 through a bearing. The motor 33 is connected to the transmission shaft 32 through a coupling. There are multiple stirring paddles 34. The rotation of the stirring paddles 34 drives the water source in the heat exchange box 21 to move, thereby making the water source and the spiral pipe 23 fully contact.

[0050] In some embodiments, as Figure 1 As shown, a water inlet pipe 211 is fixedly connected to the heat exchange box body 21 , and a flange is provided at one end of the water inlet pipe 211 away from the heat exchange box body 21 .

[0051] Furthermore, the water inlet pipe 211 is connected to an external pipeline through a flange, and cold water is brought into the heat exchange box 21 through the water inlet pipe 211.

[0054] In some embodiments, as Figure 2 As shown, a control valve 251 is installed at the water outlet end of the manifold 25 , and the control valve 251 is used to control the opening and closing of the manifold 25 .

[0055] Furthermore, a control valve 251 is installed at the open end of the manifold 25 , and the control valve 251 is opened to discharge the distilled water collected in the manifold 25 .

[0058] The working principle of this application is described below with a preferred embodiment:

[0059] Cold water is introduced into the heat exchange box 21 through the water inlet pipe 211. When the drying tank 1 is used to dry rice, the hot steam generated in the drying tank 1 enters the air guide pipe 222 through the top cover 221. When the steam enters the heat-conducting shell 223 along the air guide pipe 222, the mesh plate 224c located in the air guide shell 223 filters the impurities in the steam. Then the steam enters the spiral pipe 23, and the heat in the steam is transferred to the spiral pipe 23. Then, the cold water in the heat exchange box 21 and the heat on the spiral pipe 23 are exchanged, and the cold water in the heat exchange box 21 is heated. The distilled water generated after the steam condenses in the spiral pipe 23 is collected into the manifold 25 along the branch pipe 24. The steam after cooling is discharged through the vertical pipe 231a and the exhaust elbow 231b. Open the control valve 251 in the manifold 25 to collect the distilled water in the manifold 25, start the motor 33 to drive the drive shaft 32 to rotate in the fixed disk 31, and then the stirring paddle 34 on the drive shaft 32 stirs the cold water in the heat exchange box 21 to make the cold water and the spiral pipe 23 fully contact, thereby improving the heat exchange efficiency of the cold water. However, when the stirring paddle 34 needs to be maintained, rotate the bolt 352 in the arc plate 351, the bolt 352 and the fixed disk 31 are separated, and then the drive shaft 32 is removed from the heat exchange box 21 for cleaning, rotate the sealing plug 224a and the air guide shell 223 to separate, move the sealing plug 224a upward to drive the connecting rod 224b to remove the mesh plate 224c from the air guide shell 223, and then clean the impurities retained in the air guide shell 223.
