In addition to containing a large amount of industrial pollutants, most of these wastewaters have a common characteristic of high temperature. High-temperature industrial wastewater discharged into the environment will cause great harm to animals and plants. The wastewater still contains a large amount of heat energy. If the heat is allowed to dissipate into the air after the wastewater is discharged, it will cause great waste. Therefore, it is necessary to use a wastewater heat recovery device to recover the heat energy.

In the production of industrial equipment, not only hot wastewater is generated, but also high-temperature exhaust gas. However, this part of exhaust gas cannot be used together with the hot wastewater recovery device at the same time, and an additional recovery device is required for heat recovery. The single heat recovery through hot wastewater will result in poor heating effect on the water source to be heated, resulting in low recovery efficiency of the wastewater heat recovery device and poor practicality.

[0023] The water heating mechanism 1 heats the inside of the water tank 101 by means of hot waste water, and the gas heating mechanism 2 enables the inside of the water tank 101 to be heated by means of hot waste gas.

[0024] The water heating mechanism 1 comprises a water tank 101, a heat distribution box 102 is fixed to one side of the water tank 101, a first water heat pipe 103 is fixed to the inner wall of the water tank 101, a second water heat pipe 104 is fixed to the inner wall of the heat distribution box 102, and the first water heat pipe 103 is connected to the second water heat pipe 104;

[0025] The hot waste water is connected to the top of the first water heat pipe 103 through the upper outer side of the water tank 101. After the hot waste water passes through the surface of the first water heat pipe 103, the water source filled in the water tank 101 can obtain a heating effect through the thermal radiation of the first water heat pipe 103, thereby realizing the recovery and conversion of heat energy. The hot water diverted into the second water heat pipe 104 will be heated inside the heat tank 102 through thermal radiation, and will flow back to the first water heat pipe 103 again. The hot water inside the first water heat pipe 103 can flow out through the bottom of the water tank 101.

[0026] The gas heating mechanism 2 includes a blower 201, which is fixed to the top of the water tank 101. One side of the blower 201 is connected to the top of the heat distribution box 102 through a pipeline. The bottom of the heat distribution box 102 is connected to an air supply pipe 202, and the surface of the air supply pipe 202 is connected to an aeration pipe 203. The aeration pipe 203 is connected to the bottom of the water tank 101. The surface of the air supply pipe 202 is connected to a shunt pipe 204, and a solenoid valve 208 is installed on the surface of the shunt pipe 204. The surface of the shunt pipe 204 is connected with a plurality of first gas heat pipes 205, the first gas heat pipes 205 penetrate the water tank 101, the first gas heat pipes 205 are located inside the water tank 101, the top of the first gas heat pipes 205 is connected with an outlet pipe 206, the surface of the water tank 101 penetrates a second gas heat pipe 209, one end of the second gas heat pipe 209 penetrates into the heat distribution box 102 and is connected with a retarder 210, one end of the retarder 210 penetrates the heat distribution box 102;

[0027] The blower 201 can deliver air to the heat distribution box 102, and the first water heat pipe 103 can heat the inside of the heat distribution box 102, so that the hot air inside the heat distribution box 102 can be input into the aeration pipe 203 through the air delivery pipe 202, and then transported to the inside of the water tank 101 by the aeration pipe 203, so that bubbles are generated in the water flow inside the water tank 101. The formation of bubbles can increase the contact area between water and heat source, promote heat transfer and mixing effects, and improve heating efficiency. At the same time, the movement of bubbles can destroy the thermal boundary layer in the water, accelerate the diffusion and transfer speed of heat, and part of the hot air can enter the first gas heat pipe 205 through the shunt pipe 204. The first gas heat pipe 205 Pipe 205 can further heat the water source inside the water tank 101 by heat transfer, thereby improving the heating efficiency of the water flow. When external exhaust gas is connected, the solenoid valve 208 is closed, and the exhaust gas is added to the gas pipe 207 and the second gas heat pipe 209. The heat in the exhaust gas will be transferred to the first gas heat pipe 205 and the second gas heat pipe 209, and they can transfer heat to the water flow, so that the water flow inside the water tank 101 can be further heated. At the same time, the hot exhaust gas inside the second gas heat pipe 209 can enter the retarder 210, and the retarder 210 can disperse the heat to the inside of the heat distribution box 102, thereby increasing the temperature of the hot air output by the gas pipe 202.

[0028] Furthermore, the first gas heat pipe 205 is arranged in a spiral structure;

[0029] The spiral first gas heat pipe 205 can increase the heat exchange area, improve the heat exchange efficiency, and can also reduce the exhaust gas flow rate and increase the heat exchange time.

[0030] Furthermore, heat sinks 105 are fixed on the surfaces of the first water heat pipe 103 and the second water heat pipe 104;

[0031] The heat sink 105 can accelerate the heat transfer effect between the surfaces of the first water heat pipe 103 and the second water heat pipe 104 , thereby improving the heating efficiency of the water flow inside the water tank 101 .

[0032] Furthermore, one-way valves 211 are installed on the surfaces of the second water heat pipe 104, the gas supply pipe 207 and the gas delivery pipe 202;

[0033] This prevents waste water in the middle of the first water heat pipe 103 from flowing back into the second water heat pipe 104 , prevents water flow inside the water tank 101 from flowing into the gas pipe 202 , and prevents hot air inside the diversion pipe 204 from flowing out from the surface of the gas filling pipe 207 .

[0036] Furthermore, the first water heat pipe 103, the second water heat pipe 104 and the slow-down pipe 210 are all arranged in a serpentine structure;

[0037] This shape design can slow down both the gas and the liquid, thereby increasing the heat exchange time.

[0038] Furthermore, a controller 3 is fixed on the surface of the water tank 101, and the input end of the controller 3 is electrically connected to the output end of the temperature sensor 106, and the output end of the controller 3 is electrically connected to the input end of the blower 201, the solenoid valve 208 and the electric heating pipe 212;

[0039] The temperature sensor 106 can transmit signals to the controller 3, and the operator can observe the internal temperatures of the water tank 101 and the heat distribution box 102 through the controller 3. The controller 3 can also operate the blower 201, the solenoid valve 208 and the electric heating tube 212.
