[0011] As can be seen from the above technical solution, this application provides an energy-saving and environmentally friendly system for wine fermentation, including a fermentation device, a cooling water treatment device, and a wastewater treatment device. The fermentation device includes a fermentation tank, a container for wine fermentation. A feed pipe is installed at the top of the fermentation tank to feed the wine fermentation raw materials into it. An agitator is installed inside the fermentation tank to agitate the raw materials during fermentation, thereby improving fermentation efficiency and accelerating the exchange of heat generated during fermentation with the cooling water, ensuring precise temperature control. The input end of the agitator passes through the top of the fermentation tank and is connected to an agitator motor, providing kinetic energy support for the agitator's operation. A cooling jacket surrounds the fermentation tank, and cooling water flows through channels in the tank wall, allowing heat exchange between the cooling water and the fermentation tank as it flows, carrying away heat and cooling the tank. This cooling process provides a constant temperature environment for wine fermentation. To ensure fermentation effectiveness and improve wine quality, a temperature detection device is installed on the side wall of the fermentation tank, passing through the cooling jacket. This device monitors the internal temperature of the fermentation tank in real time and transmits the detected temperature information back to the PLC controller. The PLC controller then controls the opening size of the cooling water inlet valve and the cooling water outlet valve, thereby controlling the flow rate and volume of the cooling water for precise temperature control. The cooling jacket is equipped with a cooling water inlet pipe and a cooling water outlet pipe. The cooling water inlet pipe is the pipe through which cooling water enters the cooling jacket, while the cooling water outlet pipe is the pipe through which the high-temperature cooling water generated after heat exchange flows out of the cooling jacket. The cooling water inlet pipe is equipped with a cooling water inlet valve, which controls the opening and closing of the internal channel and the flow rate of the cooling water under the control of the PLC controller. The cooling water outlet pipe is connected to a cooling water treatment device at its end.

[0012] The cooling water treatment device includes a water storage tank, a container for storing water used to clean equipment such as fermentation tanks. The top of the water storage tank is equipped with an inlet and a return pipe. The inlet is a channel for injecting water into the tank, and the return pipe is a pipe through which water treated by the wastewater treatment device flows back to the storage tank. The outside of the storage tank is encased in a heating jacket. The high-temperature cooling water, after heat exchange, flows through channels in the tank wall, allowing the high-temperature cooling water to heat the tank during its flow. This heat exchange process heats the water inside the tank, replacing traditional electric heating of the water and achieving heat recovery and energy saving. The heating jacket is equipped with a hot water inlet pipe and a hot water outlet pipe. The hot water inlet pipe leads to the outlet pipe... High-temperature cooling water discharged from the pipe flows into the pipes inside the heating jacket. The hot water outlet pipe is where the cooled water inside the heating jacket, after heat exchange, flows out of the heating jacket. The hot water inlet pipe is connected to the cooling water outlet pipe, and the end of the hot water outlet pipe is connected to the cooling tower. This is a mechanism for cooling the water after heat exchange. The cooling tower is equipped with a spray trough to disperse and spray the cooled water inside the tower. This disperses the cooled water inside the cooling tower, increasing the contact area between the airflow generated by the fan and the cooled water, thus achieving rapid cooling. The spray trough inlet is connected to the hot water outlet pipe, and the top of the cooling tower... The cooling tower has an air outlet and a fan channel. A fan is installed at the outlet, and the fan motor generates suction, which, combined with the air inlet, allows for rapid airflow within the cooling tower. This efficiently removes residual heat from the cooling water after heat exchange, achieving the purpose of cooling the water. The fan is connected to the fan motor via a belt, and the kinetic energy output structure provides power support for the fan's operation. Air inlets are located on the side wall of the cooling tower, forming a channel with the air outlet to allow airflow within the cooling tower under the action of the fan. Multiple baffles are installed inside the cooling tower to block the falling, warm cooling water, preventing it from entering the tower. After the impact, the flow becomes more dispersed and the flow rate decreases, extending the cooling time of the heated cooling water, improving the cooling efficiency of the cooling tower, and enhancing the cooling effect of the cooling tower. The cooling tower sidewall is connected to a drain pipe, which discharges the cooled water to the fermentation device. The drain pipe is connected to a drain valve and a drain pump in sequence from front to back. The drain valve plays a control role, controlling the opening and closing of the internal channel of the drain pipe and the flow rate of the cooling water in the drain pipe under the control of the PLC controller, providing strong support for changes in the flow rate and velocity of the cooling water. The drain pump is a kinetic energy output structure that outputs kinetic energy to transport the cooled water from the cooling tower to the fermentation device through the drain pipe. The end of the drain pipe is connected to the cooling water inlet pipe.

[0013] The bottom of the fermentation tank is equipped with a discharge pipe, a wine outlet pipe, and a wastewater discharge pipe. The discharge pipe is a channel for draining waste residue, residual wine (in negligible quantity), and wastewater (in negligible quantity) from the fermentation tank. The wine outlet pipe is for draining the fermented wine from the fermentation tank. The wastewater discharge pipe is for draining wastewater generated during fermentation and wastewater from cleaning the fermentation tank. A discharge valve is installed on the discharge pipe to control the opening and closing of the internal channels. The valve remains closed during wine fermentation, wine discharge, and wastewater discharge to prevent the outflow of fermentation materials, wine, and wastewater. The valve is opened only after fermentation is complete and the wine and wastewater have been drained, allowing the waste residue and residual wine to be discharged. (Very small amount, negligible) and wastewater (very small amount, negligible). The wine outlet pipe is equipped with a wine outlet valve, which controls the opening and closing of the internal channel. During wine fermentation, it remains closed to ensure complete fermentation. After fermentation, it is opened to allow the fermented wine to drain from the outlet pipe. The wastewater outlet pipe is equipped with a wastewater outlet valve, which controls the opening and closing of the internal channel. During wine fermentation, it remains closed to ensure complete fermentation. After fermentation, it is opened to allow wastewater generated during fermentation and wastewater from cleaning the fermentation tank to flow out from the wastewater outlet pipe. The end of the wastewater outlet pipe is connected to a wastewater treatment device, which includes a sludge tank and filters. The wastewater collection system includes a temporary storage container for impurities. An outlet pipe is located at the bottom of the wastewater collection box, allowing temporarily stored impurities to drain out. The outlet pipe is capped for sealing during wastewater discharge to prevent wastewater from exiting. After discharge, the pipe is opened to allow the filter screen to remove the temporarily stored impurities for reuse. The side wall of the wastewater collection box has an outlet hole with a welded groove for holding the filter screen. The filter screen filters the wastewater flowing from the wastewater collection box, allowing it to pass through the mesh and enter the activated carbon adsorption device, where impurities are trapped within the wastewater collection box, achieving primary purification. One side of the groove is connected to… The system includes an activated carbon adsorption device for adsorption and purification. Utilizing the specific adsorption properties of activated carbon, it treats the wastewater after primary purification by adsorbing and removing pigments and micro-impurities to produce purified primary water. The output of the activated carbon adsorption device is connected to a pH adjustment tank, a container for adjusting the pH of the primary water. The pH adjustment tank contains a mixing mechanism that agitates the primary water and the added pH adjuster, ensuring thorough mixing and accelerating pH adjustment. This also makes the pH readings from the pH detection device more accurate. The mixing mechanism has a motor connected to its input, providing power for the agitation operation. A pH adjuster inlet pipe is located at the top of the pH adjustment tank.A pH adjuster flows from the adjuster tank into the pH adjusting tank via a pipe. An inlet valve on the adjuster inlet pipe controls the opening and closing of the internal channel under the control of a PLC controller. This, combined with a pH detection device, allows for precise pH adjustment of the primary water to purify it into qualified water. The inlet end of the adjuster inlet pipe is connected to the adjuster tank, the storage container for the pH adjuster. A pH detection device is installed on the side wall of the pH adjusting tank to detect the pH value of the water in the tank in real time and transmits the detected pH value back to the PLC controller. The PLC controller then compares the transmitted value with the threshold value input on the PLC to determine the dosage of the pH adjuster. The system allows for precise pH adjustment of the primary water. A treated water discharge pipe is installed on the side wall of the pH adjustment tank. The qualified water produced after pH adjustment is discharged from the pH adjustment tank through this pipe. The treated water discharge pipe is equipped with a treated water discharge valve and a treated water return pump, arranged sequentially from front to back. The treated water discharge valve controls the opening and closing of the internal passage of the treated water discharge pipe. During the pH adjustment of the primary water in the pH adjustment tank, it remains tightly closed to ensure complete pH adjustment. After the primary water in the pH adjustment tank is converted to qualified water, the valve is opened, allowing the qualified water to flow back to the storage tank under the action of the treated water return pump, thus achieving wastewater recycling and environmental protection. The end of the treated water discharge pipe is connected to the return pipe.

[0014] The stirring motor, cooling water inlet valve, cooling water outlet valve, temperature detection device, fan motor, drain valve, drain pump, impurity discharge valve, wine outlet valve, wastewater discharge valve, activated carbon adsorption device, mixing motor, regulator inlet valve, pH detection device, treated water outlet valve, and treated water return pump are all connected to the same PLC controller, which plays a control role, controlling the coordinated operation of various electrical control components to achieve precise temperature control of the fermentation tank, recycling of cooling water, and recovery of wastewater.

[0016] 1. An advanced PLC intelligent control system is adopted, which realizes the automatic control of cooling water flow rate and velocity by controlling the opening and closing of the cooling water inlet valve and the cooling water outlet valve.

[0027] From the above technical solutions, it can be seen that:

[0028] Example 1:

[0029] See Figures 1-4 .

The fermentation device includes a fermentation tank 1, the container for wine fermentation. A feed pipe 2 is installed at the top of the fermentation tank 1 to feed the wine fermentation raw materials. An agitator 3 is installed inside the fermentation tank 1 to agitate the raw materials during fermentation, improving fermentation efficiency and accelerating the exchange of heat generated during fermentation with the cooling water, ensuring precise temperature control. The input end of the agitator 3 passes through the top of the fermentation tank 1 and is connected to an agitator motor 4, providing kinetic energy for the agitator's operation. A cooling jacket 5 surrounds the outside of the fermentation tank 1, through which cooling water flows. As the cooling water flows through the walls of the fermentation tank 1, it exchanges heat with the fermentation tank 1, carrying away heat and cooling the interior of the fermentation tank 1. This provides a constant temperature environment for wine fermentation, ensuring optimal fermentation results. To improve wine quality, a temperature detection device 10 is installed on the side wall of the fermentation tank 1, passing through the cooling jacket 5. This device monitors the internal temperature of the fermentation tank 1 in real time and transmits the detected temperature information back to the PLC controller. The PLC controller then controls the opening size of the cooling water inlet valve 7 and the cooling water outlet valve 9, thereby controlling the flow rate and volume of the cooling water for precise temperature control. The cooling jacket 5 is equipped with a cooling water inlet pipe 6 and a cooling water outlet pipe 8. Cooling water enters the cooling jacket 5 through the cooling water inlet pipe 6. The cooling water outlet pipe 8 is a pipe through which the high-temperature cooling water generated after heat exchange flows in the cooling jacket 5 and is discharged.

The outside of the water storage tank 11 is wrapped with a heating jacket 12. The high-temperature cooling water, after heat exchange, flows through channels in the wall of the water storage tank 11, thus heating the water storage tank 11 by utilizing the principle of heat exchange during its flow.

The inlet of the spray tank 16 is connected to the hot water outlet pipe 13. The top of the cooling tower 17... The cooling tower 17 has an air outlet 18 and a channel for a fan 19. The fan 19, powered by a motor 21, generates suction, which, combined with the air inlet 22, allows for rapid airflow within the cooling tower 17. This efficiently removes residual heat from the cooling water after heat exchange, achieving the purpose of cooling the water. The fan 19 is connected to the motor 21 via a belt, providing kinetic energy for its operation. The cooling tower 17 also has air inlets 22 on its side wall. The cooling tower 17 forms a channel with the air outlet 18, allowing the air inside the cooling tower 17 to flow under the action of the fan 19. Multiple diverter plates 24 are installed inside the cooling tower 17 to block the falling, warm cooling water, causing it to disperse more after impact and reducing its flow velocity, thus prolonging the cooling time and improving the cooling efficiency and effect of the cooling tower 17. A drain pipe 25 is connected to the side wall of the cooling tower 17 to discharge the cooled water after cooling in the cooling tower 17 to a source. The fermentation apparatus has a drain pipe 25 with a drain valve 27 and a drain pump 26 connected sequentially from front to back. The drain valve 27 acts as a control valve, controlling the opening and closing of the internal channel of the drain pipe 25 and the flow rate of the cooling water within the drain pipe 25 under the control of the PLC controller, providing strong support for changes in the flow rate and velocity of the cooling water. The drain pump 26 is a kinetic energy output structure that outputs kinetic energy to transport the cooling water, cooled by the cooling tower 17, from the cooling tower 17 through the drain pipe 25 to the fermentation apparatus.
