[0047] The working principle of this utility model is as follows:

[0048] After cooling one of the reactors, such as the second reactor 130, by using the cooling oil, in order to make full use of the waste heat contained in the cooling oil, the above-mentioned utility model is used, and the cooling heat transfer oil pump 330 is used to recover the cooling oil. The oil outlet of the cooling heat transfer oil pump 330 is fluidically connected to the oil inlet of the cooler 340, and the oil outlet of the cooler 340 is fluidically connected to the oil inlet of another reactor, such as the first reactor 120, through the cold oil pipeline 350. The cooling is started. The thermal oil pump 330 is used, and the cooling oil heated by heat exchange enters the first reactor 120 through the cooler 340 and the cold oil pipeline 350. The cold material in the first reactor 120 is heated by the cooling oil with waste heat to increase the temperature, thereby realizing the recovery and utilization of the heat in the thermal oil used for cooling. The thermal oil cooled by the first reactor 120 can be used for cooling again after being cooled by the cooler 340, thereby reducing the amount of coolant used in the cooling process and reducing the energy consumption of the enterprise production.

[0049] The thermal oil heating system 200 and the thermal oil cooling system 300 of the present invention adopt the interlocking operation of the three buttons "cooling / stopping / heating" for automatic control. For example: when the first reactor 120 is heated, the first cold oil inlet valve and the first cold oil return valve are closed first, and then the first cold oil inlet valve and the first cold oil return valve are judged to be fully closed. After judging that they are fully closed, the first hot oil inlet valve and the first hot oil return valve are opened for heating. When the second reactor 130 is cooled, the second hot oil inlet valve and the second hot oil return valve are closed first, and then the second hot oil inlet valve and the second hot oil return valve are judged to be fully closed. After judging that they are fully closed, the second cold oil inlet valve and the second cold oil return valve are opened for heating. When the second reactor 130 stops heat exchange, the second hot oil inlet valve and the second cold oil inlet valve are closed first, and then the second hot oil inlet valve and the second cold oil inlet valve are judged to be fully closed. After judging that they are fully closed, the second hot oil return valve and the second cold oil return valve are opened. If it is judged that any valve is not in place during the execution of an action, the next action will not be executed;

[0050] If the valve feedback signal fails or the valve has internal leakage, hot oil will flow into the thermal oil cooling system 300. To cope with the situation of valve feedback signal failure or valve internal leakage, the high-level expansion tank 310 is equipped with a high-level expansion tank temperature sensor 311 and a high-level expansion tank liquid level sensor 312 with remote transmission function to determine the temperature and liquid level inside the high-level expansion tank 310, while the low-level oil tank 320 is equipped with a low-level tank temperature sensor with remote transmission function, a low-level oil tank 320 liquid level upper limit sensor, and a low-level oil tank 320 liquid level lower limit sensor to determine the temperature and liquid level inside the low-level oil tank 320. After the cooling thermal oil pump 330 is started, it will first determine whether the high-level expansion tank temperature sensor 311, the high-level expansion tank liquid level sensor 312, the low-level oil tank temperature sensor 323, the low-level oil tank liquid level upper limit sensor 321 and the low-level oil tank liquid level lower limit sensor 322 have any display. If there is no display, the heat exchange will proceed normally. Otherwise, the first temperature-liquid level interlock pneumatic valve 351 and the second temperature-liquid level interlock pneumatic valve 352 will be immediately closed to disconnect the system for double protection and issue a corresponding alarm.

[0051] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
