Description

Technical Field

[0001] The utility model belongs to the field of edible oil processing, and particularly relates to a temperature control system for a flavor oil reactor. Background Art

[0002] When processing edible oil, in order to give it a special flavor, it needs to be heated and reacted with specific raw materials in a reactor. Existing reactor heating devices generally use electric heating, and their temperature control can only increase in one direction. There is a lack of precise temperature control, making it difficult to achieve the optimal reaction temperature. Utility Model Content

[0003] The purpose of this utility model is to provide a temperature control system for a flavor oil reactor in order to solve the above problems.

[0004] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0005] A temperature control system for a flavor oil reactor comprises a heat exchange tube wound around the surface of the reactor, a heating branch and a cooling branch connected in parallel between the two ends of the heat exchange tube, wherein the cooling branch comprises a cooling tank and a first medium pump, and the cooling tank has an external heat exchange circuit; the heating branch comprises a gas-liquid separator, a second medium pump, and a heater; the medium enters from the inlet of the gas-liquid separator and is discharged from the outlet at the top; the medium outlet at the bottom of the gas-liquid separator is connected to an expansion tank; and an exhaust pipe is further provided at the inlet end of the heating branch near the gas-liquid separator and connected to the upper end of the expansion tank.

[0006] As a further optimization solution of the present invention, a sensor group is further provided at the outlet end of the heater. The sensor group includes a temperature sensor, a pressure sensor, and a flow meter. By setting the sensor group, various parameters of the medium in the heating circuit can be monitored in real time.

[0007] As a further optimization scheme of the present invention, solenoid valves are provided at the starting point and end point of the heating branch and the cooling branch, and solenoid valves are provided between the cooling tank and the first medium pump, between the gas-liquid separator and the second medium pump, and between the second medium pump and the heater. By setting up each solenoid valve, when the heating branch or the cooling branch is running, the other branches are closed, or the various pipelines are conveniently disassembled and assembled during maintenance.

[0008] As a further optimization solution of the present invention, a filter is provided at the inlet end of the second medium pump for removing impurities in the medium.

[0009] As a further optimization solution of the present invention, the height of the expansion tank is higher than the height of the heat exchange tube, the heating branch and the cooling branch. The expansion tank has a liquid level gauge, and the expansion tank is used to compensate for thermal expansion and contraction in the heating branch and the cooling branch.

[0010] As a further optimization scheme of the present invention, a gas recovery component is provided at the three-way connection between the exhaust pipe and the heating branch, and the gas recovery component includes a tube body strung in the heating branch, and a tortuous channel is provided at the upper end of the tube body, and the top of the tortuous channel is connected to the exhaust pipe, and the liquid level in the tortuous channel is consistent with the liquid level of the expansion tank through the principle of a communicating vessel, and a gate plate and a gate plate groove are provided in the tube body, and a float is provided in the tortuous channel, and the float is connected to the gate plate through a connecting piece. When the float rises with the liquid level, the gate plate is pulled up to cut off the tube body, thereby making the medium bypass the tortuous channel. By setting the gas recovery component, the gas recovery efficiency is improved when the medium temperature is too high.

[0011] As a further optimization solution of the present invention, an exhaust valve is provided in the exhaust pipe, which is used to control opening and closing, so that the high-temperature gas of the heating branch directly enters the expansion tank through the exhaust pipe.

[0012] The beneficial effects of the present invention are:

[0013] The utility model can heat or cool the reactor by setting a heating branch and a cooling branch, and can perform stable and precise regulation through the dual channels. When heating is required, the heater and the second medium pump are operated to form a cycle to heat the reactor, and the thermal expansion and contraction are compensated by the expansion tank. The flow direction of the high-temperature and high-pressure gas is controlled by the gas-liquid separator and the exhaust pipe, so that the high-temperature and high-pressure gas in this part directly enters the cavity of the expansion tank and further overflows to the external environment without adding oil to the expansion tank, which helps to avoid the oil temperature in the expansion tank being too high and affecting the service life of the expansion tank.

[0018] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example 1

[0020] like Figure 1-3 As shown, a temperature control system for a flavor oil reactor includes a heat exchange tube 1 wrapped around the surface of a reactor 6, with a heating branch and a cooling branch connected in parallel between the two ends of the heat exchange tube 1. The cooling branch includes a cooling tank 21 and a first medium pump 23. The cooling tank 21 has an external heat exchange circuit 22. The heating branch includes a gas-liquid separator 31, a second medium pump 33, and a heater 34. The medium enters from the inlet of the gas-liquid separator 31 and is discharged from the top outlet. The medium outlet at the bottom of the gas-liquid separator 31 is connected to an expansion tank 42. An exhaust pipe 44 is also provided near the inlet end of the heating branch near the gas-liquid separator 31 and is connected to the upper end of the expansion tank 42.

[0021] In this solution, oil is used as the medium, which has a higher heating upper limit. When heating is required, the heater 34 and the second medium pump 33 are operated to form a cycle to heat the reactor 6. The medium contains high-temperature and high-pressure gas, which enters the hollow part of the expansion tank 42 through the exhaust pipe 44 when passing through the exhaust pipe 44. The gas-liquid separator 31 is a prior art, including an inlet, a gas outlet at the upper end, and a medium outlet at the lower end. In this solution, in order to prevent a large amount of high-temperature and high-pressure gas from entering the expansion tank 42 to heat the medium in the expansion tank 42, after the oil and gas are separated in this application, pure oil enters the expansion tank 42, and the oil-gas mixture continues to enter the heating circuit from the upper end outlet and flows back to the expansion tank 42 at the exhaust pipe 44. The high-temperature and high-pressure gas is recovered through the exhaust pipe 44, so that the high-temperature and high-pressure gas in this part directly enters the cavity of the expansion tank 42 and further overflows to the external environment without adding oil to the expansion tank 42, which helps to avoid the oil temperature in the expansion tank 42 being too high and affecting the service life of the expansion tank 42.

[0022] The cooling branch exchanges heat with the cold source through the cooling tank 21 and the heat exchange loop 22 to achieve the purpose of appropriate temperature reduction.

[0023] Furthermore, a sensor group 35 is provided at the outlet end of the heater 34. The sensor group 35 includes a temperature sensor, a pressure sensor, and a flow meter. By providing the sensor group 35, various parameters of the medium in the heating circuit can be monitored in real time.

[0024] Solenoid valves are provided at the starting point and end point of the heating branch and the cooling branch. Solenoid valves are provided between the cooling tank 21 and the first medium pump 23, between the gas-liquid separator 31 and the second medium pump 33, and between the second medium pump 33 and the heater 34. By setting up each solenoid valve, when the heating branch or the cooling branch is running, the other branches are closed, or the various pipelines are conveniently disassembled and assembled during maintenance. A filter 32 is provided at the inlet end of the second medium pump 33 for filtering impurities. Furthermore, a solenoid valve connected to the outside can also be provided in the heating branch to facilitate the discharge or injection of the medium.

[0025] The height of the expansion tank 42 is higher than the height of the heat exchange tube 1, the heating branch and the cooling branch. The expansion tank 42 has a liquid level gauge 43. A gas recovery component 5 is provided at the three-way connection between the exhaust pipe 44 and the heating branch. The gas recovery component 5 includes a pipe body 51 strung in the heating branch. A tortuous channel 52 is provided at the upper end of the pipe body 51. The top of the tortuous channel 52 is connected to the exhaust pipe 44, and the liquid level in the tortuous channel 52 is consistent with the liquid level of the expansion tank 42 through the communicating vessel principle. A gate 54 and a gate groove 53 are provided in the pipe body 51, and a float 55 is provided in the tortuous channel 52. The float 55 is connected to the gate 54 through a connecting piece 56. When the liquid level rises, the float 55 pulls up the gate 54 to cut off the pipe body 51, thereby allowing the medium to bypass the tortuous channel 52. An exhaust valve 41 is provided in the exhaust pipe 44. By providing the gas recovery component 5, the gas recovery efficiency is improved when the medium temperature is too high.

[0026] Specifically, when the oil temperature is too high, the liquid level in the expansion tank 42 rises due to thermal expansion and contraction, and the liquid level in the meandering channel 52 is made consistent with the height of the expansion tank 42 through the communicating vessel principle, and the liquid level in the meandering channel 52 also rises, and the float 55 rises and pulls up the gate 54, so that the oil in the tube body 51 bypasses the meandering channel 52 and is discharged at the upper end of the meandering channel 52, and then the oil flows back downward into the tube body 51. Sufficient lateral flow space is set at the top of the meandering channel 52, which helps bubbles to converge upward instead of entering the tube body 51 again. When the oil temperature is low, the liquid level in the expansion tank 42 drops, and the liquid level in the meandering channel 52 drops to Figure 3 As shown, a small amount of bubbles can still move upward through the meandering channel.

[0027] It should be noted that due to the difference in liquid flow rate, there may be a difference in the liquid level height in the expansion tank 42 and the tortuous channel 52, and the liquid levels are not necessarily exactly the same. This liquid level difference does not affect the gas recovery component 5. As long as the liquid level changes in the tortuous channel 52, the float 55 can be raised and lowered, thereby achieving automatic opening of the gas recovery component 5.

[0028] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
