Description

Technical Field

[0001] This utility model relates to the field of industrial exhaust gas treatment technology, specifically to an industrial exhaust gas waste heat utilization device. Background Technology

[0002] Industrial exhaust gas refers to the general term for various pollutant-containing gases emitted into the air during fuel combustion and production processes within a factory area. Industrial exhaust gas also contains a large amount of waste heat, which, if not recovered and utilized, will result in a waste of heat and is also detrimental to environmental protection requirements.

[0003] In the prior art, patent document CN220437223U discloses an industrial exhaust gas waste heat utilization device, including a hot water tank. An inlet pipe is fixedly installed on the upper right side wall of the hot water tank, and an outlet pipe is fixedly installed on the lower right side wall. By setting up a high-efficiency heat exchange mechanism, the high thermal conductivity spiral honeycomb heat exchange tubes on the mechanism are made of polycrystalline diamond ceramic and have a spiral shape, which increases the contact area between the tubes and the water in the hot water tank, improving their thermal conductivity. Simultaneously, the high thermal conductivity spiral honeycomb heat exchange tubes have honeycomb-shaped airflow channels inside, which are connected to the inlet pipe. The exhaust gas in the inlet pipe is evenly distributed in the honeycomb-shaped airflow channels inside the high thermal conductivity spiral honeycomb heat exchange tubes, increasing the contact area between the exhaust gas and the inside of the high thermal conductivity spiral honeycomb heat exchange tubes, improving their thermal conductivity, and thus improving the overall heat exchange efficiency of the waste heat utilization device.

[0004] To address the issue of existing industrial exhaust gas waste heat recovery devices, which typically employ exhaust gas-water heat exchange, the exhaust gas transfers heat through a heat-conducting medium before exchanging heat with the water. However, this method suffers from a small contact area between the exhaust gas and the heat-conducting medium. Existing technologies utilize high-efficiency heat exchange mechanisms, with high-thermal-conductivity spiral honeycomb heat exchange tubes made of polycrystalline diamond ceramic and featuring a spiral shape. However, this approach still results in the inability to circulate the heated water during operation, thus reducing the device's practicality. Summary of the Invention

[0013] A further improvement of this utility model is that: the output end of the water pump is detachably connected to an electromagnetic valve, and the input end of the electromagnetic valve is connected to the inside of the water tank.

[0014] A further improvement of the present invention is that the pumping assembly includes a second pump, the bottom surface of which is detachably connected to the upper surface of the fixed plate, and the input end of the second pump is detachably connected to a second solenoid valve, the input end of which is connected to the interior of the water tank.

The heat exchange component includes a gas conveying pipe 21, one side of which is fixedly connected to the outer surface of the water tank 1, and the other end of which is fixedly connected to a heat exchange pipe 27. A heat exchange plate 24 is fixedly connected to the outer surface of the heat exchange pipe 27, and a heat conduction plate 25 is fixedly connected to the outer surface of the heat exchange plate 24. The outer surface of the heat conduction plate 25 is fixedly connected to the outer surface of the heat exchange pipe 27, and a heat conduction plate 25 is fixedly connected to the outer surface of the heat conduction plate 25. The device includes multiple heat dissipation fins 26. The circulation assembly includes a drive motor 22, whose outer surface is detachably connected to the outer surface of the water tank 1. The drive end of the drive motor 22 is detachably connected to an agitator 23. When using the industrial exhaust gas waste heat recovery device, water is first introduced into the water tank 1. Then, industrial exhaust gas is transported to the inside of the gas transmission pipe 21. Heat exchange is then performed between the heat exchange pipe 27 and the water. During the heat exchange, the heat exchange plate 24, the heat conduction plate 25, and the heat dissipation fins 26 work together to increase the contact area between the heat exchange pipe 27 and the water, thereby increasing the heat exchange efficiency and assisting in the recovery and utilization of industrial exhaust gas waste heat. At the same time, the PLC controller 4 starts the drive motor 22 to work with the agitator 23 to slowly agitate the water inside the water tank 1, thereby using the water's fluidity to increase the water's heat exchange efficiency. Finally, the cooled industrial exhaust gas is discharged from the gas transmission pipe 21 on the other side. Example

[0022] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the water conveying assembly includes a fixing plate 31, the outer surface of the fixing plate 31 is fixedly connected to the outer surface of the water tank 1, a water pump 32 is detachably connected to the upper surface of the fixing plate 31, an electromagnetic valve 33 is detachably connected to the output end of the water pump 32, and the input end of the electromagnetic valve 33 is connected to the interior of the water tank 1.

The input end of the second water pump 34 is detachably connected to the second solenoid valve 35. The input end of the second solenoid valve 35 is connected to the inside of the water tank 1. During the heat exchange process between the water inside the water tank 1 and the heat exchange tube 27, when the temperature monitored by the thermometer reaches the preset temperature, the PLC controller 4 can be used to control the start of the first solenoid valve 33, the first water pump 32, the second water pump 34 and the second solenoid valve 35, thereby assisting in the output of hot water inside the water tank 1 and simultaneously delivering cold water to the inside of the water tank 1, thereby realizing the recycling of water.

[0024] like Figure 1-5 As shown, when using the industrial exhaust gas waste heat recovery device, water is first introduced into the water tank 1, then industrial waste gas is transported into the gas supply pipe 21. Heat exchange is then performed between the heat exchange pipe 27 and the water. Simultaneously, the heat exchange plate 24, heat conduction plate 25, and heat dissipation fins 26 work together to increase the contact area between the heat exchange pipe 27 and the water, thereby increasing the heat exchange efficiency and aiding in the recovery and utilization of industrial exhaust gas waste heat. At the same time, the PLC controller 4 starts the drive motor 22, which, in conjunction with the stirring blades 23, slowly moves the water in the water tank 1. The internal water is agitated, thereby increasing the efficiency of water heat exchange by utilizing the water's fluidity. Finally, the cooled industrial exhaust gas can be discharged from the gas supply pipe 21 on the other side. During the heat exchange process between the water inside the water tank 1 and the heat exchange pipe 27, when the temperature monitored by the thermometer reaches the preset temperature, the PLC controller 4 can be used to control the start of solenoid valve 33, water pump 32, water pump 34 and solenoid valve 35, thereby assisting in the output of hot water inside the water tank 1, while simultaneously delivering cold water to the water tank 1, thus realizing the recycling of water.
