Description

Technical Field

[0001] The present application relates to the technical field of reduced pressure distillation and cooling, and in particular to a jet vacuum pump water tank water and sewage coordinated treatment system. Background Art

[0002] At present, vacuum distillation is a commonly used production method in industrial production. It reduces the boiling point of liquid and improves production efficiency by reducing the pressure in the container through vacuum pumping. In the process of vacuum distillation of solution, the vacuum system uses a jet vacuum pump to vacuum the evaporation container. Since the high-temperature gas extracted by vacuum dissolves in the water in the water tank of the jet vacuum pump, and the jet vacuum pump generates heat when working, the water temperature in the water tank rises. When the water temperature in the water tank rises to above 40°C, the vacuum degree of the system will drop significantly, from -0.09MPa to -0.08MPa, and in severe cases less than -0.07MPa, which leads to a significant increase in distillation time and a significant reduction in production efficiency. Therefore, in order to make the vacuum system operate stably, the water in the water tank needs to be cooled.

[0003] The common methods for cooling the water in the jet vacuum pump tank are water exchange and heat exchanger cooling.

[0004] Among them, water exchange and cooling is to achieve the purpose of cooling by directly discharging the wastewater with higher temperature in the water tank and then adding tap water of normal or low temperature to the water tank. However, water exchange and cooling requires frequent water exchange, which will lead to reduced production efficiency. At the same time, the water exchange process is likely to cause instability of the production system, and the amount of tap water is large, which seriously wastes water resources and has high operating costs. In addition, the directly discharged wastewater is prone to pollution.

[0005] Based on this, a new technical solution is needed. Utility Model Content

[0030] It should also be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. The drawings only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0031] Additionally, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, it will be understood by those skilled in the art that the examples can be practiced without these specific details.

[0032] At present, during the vacuum distillation process, the water in the water tank will heat up. Once the water temperature reaches above 40°C, the vacuum degree of the system will drop significantly, which will cause the distillation time to increase significantly and the production efficiency will be greatly reduced. Therefore, it is necessary to cool the water tank to ensure production efficiency.

[0033] At present, the commonly used methods for cooling the water in the jet vacuum pump tank are water exchange cooling and heat exchanger cooling.

[0034] Among them, water exchange and cooling, that is, directly discharging the wastewater with higher temperature in the water tank and then adding tap water of normal or low temperature to the water tank, can achieve the purpose of cooling. However, water exchange and cooling requires frequent water exchange, which will lead to reduced production efficiency. At the same time, the water exchange process is likely to cause instability of the production system, and the amount of tap water is large, which seriously wastes water resources, has high operating costs, and the discharged wastewater is prone to pollution.

[0035] In summary, in view of the shortcomings of existing technologies, a new system is needed to reduce the consumption of water resources and avoid pollution.

[0036] In view of this, during the analysis and improvement exploration of the jet vacuum pump water tank cooling method and system structure design, it was found that: in the process of reduced pressure distillation, there is a step that requires sewage treatment to obtain purified water. If you want to save water resources, you can use the purified water, such as inputting it into a water tank that needs to be cooled to form a circulation system. This can not only reuse the sewage, but also cool the water tank and reduce wastewater discharge.

[0037] Based on this, this specification embodiment proposes a processing solution: Figure 1 As shown, the system includes a jet vacuum pump water tank 107, a sewage treatment unit 101, a water supply unit, and a safety assurance unit. The jet vacuum pump water tank is used to store circulating water for the jet vacuum pump; the sewage treatment unit is connected to the jet vacuum pump water tank 107 through a water outlet pipeline, and is used to purify the sewage in the jet vacuum pump water tank 107; the water supply unit includes a self-priming pump 103, which is connected to the sewage treatment unit 101 through a water outlet pipeline. The self-priming pump 103 takes water from the sewage treatment unit and inputs it into the jet vacuum pump water tank 107. The jet vacuum pump water tank 107, the sewage treatment unit 101 and the water supply unit form a loop, which can recycle the treated water; the safety assurance unit is connected to the jet vacuum pump water tank 107 through a tap water pipe to prevent the jet vacuum pump water tank from lacking water and improve the stability of the system operation.

[0038] The sewage treatment unit 101 includes biochemical treatment, coagulation and sedimentation treatment, and disinfection and sterilization treatment.

[0039] Biochemical treatment is to treat the water from the overflow port of the jet vacuum pump water tank 107 and the water from the bottom water outlet into the sewage biochemical system, remove the pollutants such as organic matter and ammonia dissolved in the water tank water when the waste gas contacts with the water tank water when the jet vacuum pump 106 is evacuated, and the water after biochemical treatment enters the coagulation and sedimentation treatment;

[0040] Coagulation and sedimentation treatment is to add drugs to the effluent after biochemical treatment to remove impurities, suspended matter, and colloids in the water, and disinfect the effluent;

[0041] The disinfection and sterilization treatment is to add a bactericide to the effluent after the coagulation and sedimentation treatment to sterilize and disinfect it, so as to kill the microorganisms in the water and obtain reusable water. The disinfected effluent enters the jet vacuum pump water tank 107.

[0042] Among them, the water supply unit takes water from the sewage treatment unit 101, filters the treated water through the filter 102 to prevent unremoved sediment, and pumps the water into the jet vacuum pump water tank 107 through the self-priming pump 103. A regulating valve 104 and a temperature sensor are arranged before the self-priming pump 103 and the jet vacuum pump water tank 107 to control the flow rate entering the water tank and the water temperature in the water tank 107. The water outlet of the overflow port of the jet vacuum pump water tank 107 and the water outlet of the bottom water outlet enter the sewage treatment unit 101 through pipelines.

[0043] Among them, the safety assurance unit, the tap water replenishment solenoid valve 105, the immersion liquid level meter 108 and the self-priming pump 103 power supply and signal access control box 109, the control box controls the self-priming pump operating current, the self-priming pump 103, the immersion liquid level meter 108 and the solenoid valve 105 are interlocked and controlled. When the self-priming pump 103 fails or the liquid level is lower than the set parameter value, the solenoid valve 105 is automatically opened for water replenishment, which can prevent the self-priming pump 103 from failing or the flow rate is reduced due to pipeline blockage, thereby preventing the jet vacuum pump water tank 107 from lacking water, protecting the safe operation of the jet pump 106, reducing equipment losses, and improving the stability of system operation.

[0044] In some embodiments, the control box is usually controlled by PLC, but it can also be other controllers, which is not limited in this application.

[0045] In some embodiments, an overflow port is provided at the top of the jet vacuum pump water tank, a water outlet is provided at the bottom, a drain valve is provided on the water outlet pipe of the water outlet, and the overflow port and the drain valve are connected to the sewage treatment unit through pipelines. The setting of the overflow port can prevent excessive sewage in the jet vacuum pump water tank from causing the system to fail to operate normally, and at the same time discharge pollutants floating on the surface.

[0046] In some embodiments, the water supply unit includes a filter, a self-priming pump, a regulating valve and a control box. The setting of the filter can further filter the water treated by the sewage treatment unit to prevent precipitation from entering the water supply unit, causing pipeline blockage and reduced flow, thereby affecting production efficiency.

[0047] In some embodiments, the filter is arranged on the outlet pipe of the sewage treatment unit, the self-priming pump is arranged on the outlet pipe of the filter, the regulating valve is arranged on the outlet pipe of the self-priming pump, and the power supply and status signal of the self-priming pump are connected to the control box.

[0048] In some embodiments, the safety assurance unit includes a solenoid valve and a submersible liquid level meter.

[0049] In some embodiments, the solenoid valve is arranged on a tap water pipe, the tap water pipe is connected to the jet vacuum pump water tank, the solenoid valve power supply and signal are connected to the control box, the immersion liquid level gauge is arranged in the jet vacuum pump water tank, the liquid level gauge power supply and signal are connected to the control box, the solenoid valve is used to control the opening and closing of the tap water pipe, and the immersion liquid level gauge is used to detect the water level in the jet vacuum pump water tank to prevent water shortage.

[0050] In some embodiments, the self-priming pump is interlocked with the solenoid valve for control. When the self-priming pump fails or the liquid level is lower than the set parameter value, the solenoid valve automatically opens to replenish the water tank of the jet vacuum pump. This can effectively prevent the self-priming pump from failing or reducing the flow rate due to pipeline blockage, which may cause the jet vacuum pump water tank to lack water.

[0051] In some embodiments, a jet vacuum pump is provided on one side of the jet vacuum pump water tank and is connected via a pipeline to provide power during vacuuming.

[0052] In some embodiments, a gas buffer tank is provided on one side of the water tank of the jet vacuum pump to prevent excessive gas during vacuum extraction, which may cause the water temperature to rise too quickly after dissolving in water. At the same time, it protects the mechanical seal of the vacuum pump and can keep the pressure in the tank in a stable state before and after the vacuum pump is operated, thereby extending the service life of the mechanical seal. It can also prevent the gas in the pump from being discharged. The gas in the buffer tank can be recovered by environmental protection recovery equipment as the gas in the pump, thereby not causing pollution to the environment.

[0053] In some embodiments, at least two regulating valves are provided, and the number of regulating valves can be increased or decreased according to different usage scenarios.

[0054] In some embodiments, the various components in the system for the coordinated treatment and utilization of water in the jet vacuum pump tank and sewage are connected through a water outlet pipeline, which is convenient for installation, maintenance and inspection.

In particular, for the product embodiment described later, since it corresponds to the method, the description is relatively simple, and the relevant parts can be referred to the partial description of the system embodiment.
