Embodiment 1

[0036] The energy supply medium is heat transfer oil. After the heat transfer oil is filled in the system, first turn on the forced circulation pump 9 of the energy supply device, use the energy exchange device 10 to heat the heat transfer oil, and then return to the energy supply medium storage tank 1, through the energy supply Controlled by the medium temperature transmitter 11, after the heat transfer oil reaches a temperature of 250°C set by the system, the energy supply medium pump 2 is turned on to deliver the heat transfer oil to each user.

[0037] Set user one B as the heat exchanger, and the temperature of the heat exchange medium must be controlled at 150°C. The heat transfer oil enters the tube side of the heat exchanger. Through the user forced circulation pump 6, the heat transfer oil is fully mixed and the temperature is uniform. Through the user temperature transmitter 12, set the target temperature to 150°C. The temperature control valve 4 is controlled and adj...

Embodiment 2

[0041] The energy supply medium is hot water. After the hot water is filled in the system, the forced hot water circulation pump 9 is first turned on, and the waste heat recovery heat exchanger 10 of the system is used to raise the temperature of the hot water, and then return to the hot water tank 1. Controlled by the water temperature transmitter 11, after the hot water reaches a temperature of 90°C set by the system, the hot water pump 2 is turned on to deliver the hot water to each user.

[0042] Set user one B as a fermentation tank, and the temperature of the materials in the tank must be controlled at 45°C. The hot water enters the hot water jacket of the fermentation tank, and the fermentation is operated at a constant temperature. The heat exchanger is forced to circulate the pump 6, so that the hot water is fully mixed and the temperature is uniform. Through the heat exchanger temperature transmitter 12, considering a certain temperature difference between inside and o...

Embodiment 3

[0046] The energy supply medium is ethylene glycol. After the ethylene glycol is filled in the system, the ethylene glycol forced circulation pump 9 is first turned on, and the Freon compressor 10 is used to cool and heat the ethylene glycol, and then return to the glycol tank 1 , Controlled by the glycol temperature transmitter 11, after the glycol reaches the system set temperature of -15°C, the glycol pump 2 is turned on to deliver the glycol to each cold user.

[0047] Set user one B as a heat exchanger, and cool the water to 10°C, and the heat exchange temperature is required to be controlled above 0°C. The ethylene glycol enters the tube side of the heat exchanger. The heat exchanger is forced to circulate the pump 6, so that the glycol is fully mixed and the temperature is uniform. Through the heat exchanger temperature transmitter 12, set the target temperature to 1°C. The temperature control valve 4 is adjusted to a suitable opening degree through the control of the tr...

Description

Technical field [0001] The invention belongs to the technical field of chemical processes, and specifically relates to a multi-stage matching energy supply device and process. Background technique [0002] The chemical industry is a high-energy-consuming industry. The core theory in the chemical industry is "three transmissions and one reverse", that is, energy transfer, mass transfer, momentum transfer and reaction engineering. Energy transfer is very common in chemical plants. The processes of heating, cooling, evaporating, condensing, and tracing materials and public engineering media are all concrete manifestations of energy transfer. Efficient use of energy, reasonable distribution of energy, making chemical equipment more green and environmentally friendly, reducing product unit consumption, thereby reducing costs and increasing profits are the constant pursuit of chemical researchers and designers. [0003] Many different types and specifications of public works and heat tr...
