Technical Field

[0001] This utility model relates to the field of heat transfer oil heating technology, specifically to a device for heating heat transfer oil using waste heat from waste liquid incineration. Background Technology

[0002] Thermal transfer oil, also known as heat transfer fluid or heat carrier oil, is an oil used as a heat exchange medium in industrial heating systems. It can provide high temperatures at relatively low vapor pressures and exhibits good thermal and chemical stability. Some enterprises require thermal transfer oil as a heat carrier to heat other materials. Depending on the process requirements, the temperature of the thermal transfer oil needs to reach 230℃ or even higher. Thermal transfer oil is typically heated using a thermal transfer oil furnace system, generally powered by natural gas, electricity, or other fuels, resulting in high energy consumption. Therefore, we propose a waste liquid incineration waste heat heating thermal transfer oil device. Summary of the Invention

[0003] The purpose of this invention is to provide a waste liquid incineration waste heat heating heat transfer oil device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides a waste liquid incineration waste heat heating heat transfer oil device, including an incineration component, a cooling component disposed on one side of the incineration component, and a heating component disposed on the side of the cooling component away from the incineration component. The heating component includes a heat exchanger, an oil inlet pipe disposed on the upper side of the heat exchanger, one end of the oil inlet pipe being disposed inside the heat exchanger, an oil pump fixedly disposed on the upper side of the heat exchanger, one end of the oil inlet pipe being fixedly connected to the oil pump, a heat exchange tube fixedly disposed inside the heat exchanger, one end of the oil inlet pipe being fixedly connected to one end of the heat exchange tube, a safety release valve and a pressure gauge No. 1 fixedly disposed on one side of the oil inlet pipe, and both the safety release valve and the pressure gauge No. 1 being disposed on the outer side of the heat exchanger.

After the flue gas is cooled inside the boiler drum, it is transported to the heat exchanger through the exhaust pipe. Then, the user starts the oil pump to transport the thermal oil to the heat exchange tube. After the flue gas inside the heat exchanger heats the thermal oil, the thermal oil is discharged to the outside through the oil outlet pipe.

A connection port 13 is fixedly installed on the upper side of the burner 12, and a fan 14 is fixedly installed on the upper side of the incinerator 11. A pipe is fixedly installed between the fan 14 and the burner 12. When using the device, the user first connects the waste liquid discharge pipe to the connection port 13, and then discharges the waste liquid into the incinerator 11. At the same time, the user starts the ignition device inside the burner 12 and the fan 14 to incinerate the waste liquid. A cooling assembly 2 is provided on one side of the incineration assembly 1. The cooling assembly 2 includes a waste heat boiler 21. A water pumping device is fixedly installed inside the waste heat boiler 21. A boiler drum 22 is fixedly installed on the upper side of the waste heat boiler 21. Multiple connecting pipes 23 are fixedly installed between the waste heat boiler 21 and the boiler drum 22. A flue gas inlet pipe 24 is fixedly installed on the lower side of the connecting pipe 23. One end of the flue gas inlet pipe 24 is fixedly connected to the incinerator 11. After the waste liquid is burned inside the incinerator 11, flue gas is generated. The flue gas enters the interior of the boiler drum 22 through the flue gas inlet pipe 24. Then, the user starts the water pumping device inside the waste heat boiler 21 to transport the water inside the waste heat boiler 21 to the interior of the boiler drum 22. The temperature of the flue gas inside the boiler drum 22 gradually decreases. A steam discharge pipe 26 is fixedly installed on the upper side of the boiler drum 22. The steam inside the boiler drum 22 is discharged to the outside through the steam discharge pipe 26.

[0023] Please see Figures 1-4As shown, a heating component 3 is provided on the side of the cooling component 2 away from the combustion component 1. The heating component 3 includes a heat exchanger 31. A flue pipe 25 is fixedly provided on the lower side of the boiler drum 22. One end of the flue pipe 25 is fixedly connected to the heat exchanger 31. After the temperature of the flue gas inside the boiler drum 22 is reduced to a specified range, the flue gas is transported to the interior of the heat exchanger 31 through the flue pipe 25. An oil inlet pipe 32 is provided on the upper side of the heat exchanger 31. One end of the oil inlet pipe 32 is located inside the heat exchanger 31. An oil pump 33 is fixedly provided on the upper side of the heat exchanger 31. One end of the oil inlet pipe 32 is fixedly connected to the oil pump 33. A heat exchange tube 34 is fixedly installed inside the heat exchanger 31. One end of the oil inlet pipe 32 is fixedly connected to one end of the heat exchange tube 34. After the flue gas inside the boiler drum 22 enters the heat exchanger 31, the user immediately starts the oil pump 33 to pump the heat transfer oil into the heat exchange tube 34. Subsequently, the heat transfer oil inside the heat exchange tube 34 exchanges heat with the flue gas inside the heat exchanger 31. An oil outlet pipe 37 is fixedly installed on the lower side of the heat exchange tube 34. One end of the oil outlet pipe 37 is located on the outside of the heat exchanger 31. After the heat transfer oil is heated to the specified temperature... The heat transfer oil is discharged to the outside of the heat exchange tube 34 through the oil outlet pipe 37. To prevent the heat exchange tube 34 from dry burning and causing the heat transfer oil to vaporize if the oil inlet pipe 32 stops operating, the oil pump 33 fails, or the heat transfer oil cannot be supplied for other reasons, a safety relief valve 35 is fixedly installed on one side of the oil inlet pipe 32. To prevent the heat transfer oil inside the heat exchange tube 34 from leaking, a first pressure gauge 36 is fixedly installed on one side of the oil inlet pipe 32, and a second pressure gauge 38 is fixedly installed on one side of the oil outlet pipe 37. The safety relief valve 35 and the first pressure gauge 36 are both located outside the heat exchanger 31. On one side of the heat exchanger 31, a flue gas discharge port is fixedly installed. After the temperature of the flue gas inside the heat exchanger 31 is reduced to a specified range, it is transported to the dust removal system through the flue gas discharge port. In order to prevent the heat transfer oil from being unable to be supplied due to the shutdown of the oil inlet pipe 32, the failure of the oil pump 33 or other reasons, a cold water nozzle 39 is fixedly installed inside the heat exchanger 31. A water pipe for supplying cold water to the inside of the cold water nozzle 39 is fixedly installed on the outside of the combustion assembly 1. When the heat transfer oil cannot be supplied, the user immediately starts the cold water nozzle 39 to quickly cool down the flue gas inside the heat exchanger 31.

[0024] In this embodiment, the waste liquid incineration waste heat heating heat transfer oil device is used by the user first connecting the waste liquid discharge pipe to the corresponding connection port 13, then starting the ignition device inside the burner 12 and the fan 14 to incinerate the waste liquid and transport it to the boiler drum 22. After the flue gas is cooled inside the boiler drum 22, it is transported to the heat exchanger 31 through the exhaust pipe 25. Then, the user starts the oil pump 33 to transport the heat transfer oil to the heat exchange tube 34. After the flue gas inside the heat exchanger 31 heats the heat transfer oil, the heat transfer oil is discharged to the outside through the oil outlet pipe 37. At the same time, the temperature of the flue gas inside the heat exchanger 31 decreases and is transported to the dust removal system through the exhaust port on one side of the heat exchanger 31. This device can convert waste liquid into flue gas to heat the heat transfer oil, which greatly reduces the energy consumption required to heat the heat transfer oil and improves the practicality of the device.
