[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1 The energy-saving heating and cooling system for a reactor shown mainly includes a mold temperature controller 1, a reactor 8, a heat exchanger 4, a landscape water tank 10, and a water pump 12. These components are connected by pipelines to form a circulation loop, constituting two circulation subsystems: an oil circulation subsystem and a water circulation subsystem.

[0020] The specific structure of the oil circulation subsystem is described below:

[0021] The mold temperature controller 1 is the heat source for the entire system, equipped with a heater and a temperature control system, which heats the oil medium to the set temperature. The oil outlet of the mold temperature controller 1 is connected to the mold temperature controller oil outlet pipe 2, which delivers the high-temperature oil medium to the subsequent piping system. The other end of the mold temperature controller oil outlet pipe 2 is connected to the inlet of a three-way fitting 3. One outlet of the three-way fitting 3 is connected to the inlet of an electric three-way valve 6 via an oil pipe 5. The other outlet of the three-way fitting 3 is connected to the inlet of the heat source channel of the heat exchanger 4, and the outlet of the heat source channel of the heat exchanger 4 is connected to the other inlet of the electric three-way valve 6. At this time, the oil medium enters the electric three-way valve 6 through the three-way fitting 3, oil pipe 5, or the heat source channel of the heat exchanger 4.

[0022] It should be noted that the electric three-way valve 6 controls the flow direction of the high-temperature oil medium. When it is necessary to heat up the batch reactor 8, the electric three-way valve 6 closes the inlet of its connection to the heat source channel of the heat exchanger 4, and the high-temperature oil medium enters the electric three-way valve 6 through the oil pipe 5. When it is necessary to cool down the batch reactor 8, the electric three-way valve 6 closes the inlet of its connection to the oil pipe 5, and the high-temperature oil medium enters the electric three-way valve 6 through the heat source channel of the heat exchanger 4.

[0023] Subsequently, the high-temperature oil medium enters the batch reactor 8 through the inlet pipe 7 connected to the electric three-way valve 6, where it exchanges heat with the material in the batch reactor 8, thereby achieving the effect of regulating the material temperature. Finally, the high-temperature oil medium flows back to the mold temperature controller 1 through the mold temperature controller return pipe 9, completing one cycle of the oil medium.

[0024] The specific structure of the water circulation subsystem is described below:

[0025] The landscape pool 10 serves as the natural cold source for the entire system, providing low-temperature water for heat exchange. The outlet of the landscape pool 10 is connected to the water pump inlet pipe 11, the other end of which is connected to the inlet of the water pump 12. The outlet of the water pump 12 is connected to the water pump outlet pipe 13. The water pump 12 is used to extract the low-temperature water from the landscape pool 10 and transport it to the subsequent water circulation loop.

[0026] The cold source channel inlet of heat exchanger 4 is connected to the water pump outlet pipe 13. An electric regulating valve 14 is installed at the connection between the water pump outlet pipe 13 and heat exchanger 4. The electric regulating valve 14 is used to control the flow rate of the low-temperature water medium. By adjusting the flow rate of the water medium entering heat exchanger 4, the temperature of the oil medium that exchanges heat with the water medium is adjusted. The water medium that exchanges heat in heat exchanger 4 flows back to landscape pool 10 through landscape pool return pipe 15, completing one cycle of the water medium.

[0027] It should be noted that the heat source channel and the cold source channel of the heat exchanger 4 of this utility model are arranged in parallel. The oil medium flowing through the heat source channel can exchange heat with the water medium flowing through the cold source channel to regulate the temperature of the oil medium.

[0028] The specific working process of this utility model is described below:

[0029] When the material in the batch reactor 8 needs to be heated, only the oil circulation subsystem of this invention is used. The mold temperature controller 1 heats the oil medium to the set temperature, and the high-temperature oil medium enters the heat source channel from the mold temperature controller's oil outlet. The high-temperature oil medium enters the three-way pipe fitting 3 through the mold temperature controller's oil outlet pipe 2, and then sequentially passes through the oil pipe 5, the electric three-way valve 6, and the batch reactor's oil inlet pipe 7 before entering the batch reactor 8 for heating. The batch reactor 8 has a jacket in the tank section, and a spiral tube is installed in the jacket. As the high-temperature oil medium flows through the spiral tube in the batch reactor 8, it fully dissipates heat and becomes a low-temperature oil medium. The low-temperature oil medium flows back from the batch reactor 8 to the mold temperature controller 1 through the mold temperature controller's return oil pipe 9 for reheating and becoming a high-temperature oil medium again. This cycle is repeated to ensure that the material in the batch reactor 8 can be continuously and stably heated. During this process, the circulation of the oil medium allows its low-temperature waste heat to be utilized, reducing energy consumption during heating. At the same time, the inlet of the heat source channel of the electric three-way valve 6 connected to the heat exchanger 4 is in a closed state, which avoids unnecessary energy loss caused by the high-temperature oil medium flowing through the heat exchanger 4 and improves the energy efficiency of the entire system.

[0030] When the material in the batch reactor 8 needs to be cooled, the oil circulation subsystem and water circulation subsystem of this invention are used simultaneously. High-temperature oil medium enters the heat source channel from the mold temperature controller's oil outlet. At this time, the inlet of the electric three-way valve 6 connected to the oil pipe 5 is closed. The high-temperature oil medium enters the three-way pipe fitting 3 through the mold temperature controller's oil outlet pipe 2, and then enters the heat source channel of the heat exchanger 4 through the three-way pipe fitting 3. Simultaneously, the low-temperature water medium from the landscape pool 10 enters the water circulation loop through the water pump 12, sequentially passing through the water pump inlet pipe 11, the water pump outlet pipe 12, and the electric regulating valve 14 before entering the cold source channel of the heat exchanger 4.

[0031] The heat source and cold source channels of heat exchanger 4 are arranged in parallel. During the flow of high-temperature oil and low-temperature water in heat exchanger 4, the high-temperature oil becomes low-temperature oil through heat exchange and then enters the batch reactor 8 through the inlet pipe 7. The low-temperature oil exchanges heat with the material in batch reactor 8 to lower the material temperature. After heat exchange, the low-temperature oil slightly increases in temperature and flows back to mold temperature controller 1 through the return pipe 9, and then enters the oil circulation loop again through the outlet of mold temperature controller 1. The low-temperature water increases in temperature through heat exchange and then flows back to the landscape water tank 10. The increased temperature of the water dissipates heat into the environment, lowering its temperature to become low-temperature water again, and then enters the water circulation loop again through the action of water pump 12. Through the above cycle, the material in batch reactor 8 is continuously and stably cooled. During this process, the water in landscape water tank 10 dissipates heat through the environment, which is a natural cold source and can reduce the energy consumption of the system. At the same time, the electric regulating valve 14 can adjust its opening to control the flow rate of the water, thereby ensuring precise control of heat exchange efficiency.

[0032] In summary, this invention integrates a traditional heating system with a natural cooling source, and achieves integrated heating and cooling functions through the design of pipelines and valves. The heat recycling function of the oil circulation subsystem and the utilization of the natural cooling source in the water circulation subsystem reduce energy consumption and operating costs. System control primarily relies on the coordinated operation of an electric three-way valve and an electric regulating valve; the coordinated use of these two valves allows for precise control of the material temperature in the reactor.

[0033] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
