Description

Technical Field

[0001] The utility model relates to the technical field of fluid accelerators, in particular to a liquor waste heat recovery and utilization system with a fluid heater. Background Art

[0002] In modern industrial production, energy efficiency and environmental protection have become increasingly important issues. As an effective means of energy conservation, waste heat utilization systems have been widely used in many industrial fields. Waste heat utilization systems usually include waste heat recovery devices and waste heat utilization equipment, which can convert waste heat generated in industrial production processes into usable thermal energy, thereby improving energy utilization efficiency and reducing energy consumption and environmental pollution.

[0003] As part of the waste heat utilization system, the main function of the fluid heater is to convert the heat energy generated by the waste heat recovery device into a high-temperature fluid that can be used in industrial production. Fluid heaters usually use advanced heat exchange technologies, such as plate heat exchangers, spiral plate heat exchangers, etc., to improve heat exchange efficiency and reduce energy loss. In addition, fluid heaters can also provide fluids of various temperature grades according to different industrial production needs to meet the requirements of different processes.

[0004] In the prior art, due to the increasing demand for waste heat utilization systems, the fluid heater will receive water from different channels, and the water temperatures of different channels will vary. The temperature change will cause the thermal stress inside the fluid heater to change, which will cause some parts of the heater to deform, crack and other problems due to uneven thermal expansion and contraction, thereby affecting the heat exchange effect and thus affecting the overall working efficiency of the waste heat utilization system. Utility Model Content

[0005] The utility model aims to provide a liquor waste heat recovery system with a fluid heater to solve the problem that the change of different water temperatures affects the working efficiency of the fluid accelerator.

[0006] The utility model is realized by the following technical solutions:

[0007] A liquor waste heat recovery and utilization system with a fluid heater, comprising:

[0008] Hot water pool system, waste heat utilization system and cold water treatment system;

[0009] The hot water tank system comprises a distillation furnace unit, a hot water tank unit and a unit driving heat source unit;

[0010] The waste heat utilization system includes a fluid heater unit, a deaerator unit, a gas boiler unit and an electrode boiler unit;

[0011] The cold water treatment system includes a cooling tower unit, a cold water pool unit, a tap water replenishment unit and a workshop ice bucket unit. By using a fluid heater in the waste heat utilization system, energy utilization efficiency can be improved.

[0012] Furthermore, the fluid heater unit includes a fluid heater body, and a premixing connector is fixedly installed at the top inlet of the fluid heater body. The premixing connector is designed to premix water of different temperatures so that the temperature of water entering the heater is relatively stable.

[0013] Furthermore, the premixing connector is integrally composed of three inlet pipes at the top, a funnel body in the middle and a transmission pipe at the bottom, which is convenient for mixing input.

[0014] Furthermore, a rotating motor is fixedly installed on the top of the premix connector, and a rotating shaft is fixedly installed on the output end of the rotating motor. The rotating shaft passes through and is rotatably installed on the top of the premix connector. The water inside the premix connector will be stirred by the mixing plate to produce a mixing effect.

[0015] Furthermore, a connecting rod is fixedly installed at the bottom of the rotating shaft, a mixing plate is fixedly installed at the bottom of the connecting rod, and the mixing plate is slidably installed on the inner side wall of the premixing connector.

[0016] Furthermore, the mixing plate is in the shape of a triangular column as a whole and has an arc-shaped top. Trapezoidal grooves are provided on both left and right side surfaces of the mixing plate. Since the trapezoidal grooves are larger at the bottom and smaller at the top, water flowing along the trapezoidal grooves will gradually aggregate, thereby producing a mixing effect.

[0017] Furthermore, inclined sliding surfaces are provided on both the front and rear side surfaces of the mixing plate, and arc plates are fixedly installed on the two oblique sides on the left and right sides of the trapezoidal notch of the mixing plate, and the arc plates can prevent impact agitation.

[0018] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0019] 1. In the utility model, the fluid heater unit uniformly mixes and heats the water of three different water temperatures to 75°C, and then transmits it to the deaerator for use. In this way, the waste heat utilization improves the working efficiency of the deaerator and reduces the waste of energy. By using the fluid heater in the waste heat utilization system, the energy utilization efficiency can be improved, thereby improving the working efficiency of the deaerator, reducing energy consumption, improving the stability and reliability of the system, reducing maintenance costs, and improving the safety of the system;

[0020] 2. The utility model is provided with a trapezoidal notch, and the water entering the premixing connector will be stirred by the mixing plate to produce a mixing effect. While the mixing plate is stirring, the water passing through the side of the mixing plate will move upward along the trapezoidal notch. Since the trapezoidal notch is larger at the bottom and smaller at the top, the water flowing along the trapezoidal notch will gradually aggregate, thereby producing a mixing effect, improving the mixing effect of the water near the mixing plate, and thus improving the overall water mixing effect;

[0021] 3. In the utility model, when water flows along the trapezoidal notch, the thrust generated by the mixing plate following the rotation and the mutual squeezing force of the water flowing and aggregating on the trapezoidal notch cause the water to be agitated and form an impact on the arc plate. The arc plate can prevent the impact from agitating, and the effect of the arc surface of the arc plate can allow the impacted water to return to the trapezoidal notch. Under the effect of preventing the impact from agitating, it also has the effect of backflow. The prevention of impact and the generation of backflow are equivalent to forming a secondary stirring and mixing, thereby improving the mixing effect of the water on the trapezoidal notch, thereby improving the overall mixing effect and making the water temperature mix faster.

[0028] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with embodiments and drawings. The schematic implementation manner of the utility model and its description are only used to explain the utility model and are not intended to limit the utility model.

[0029] like Figures 1 to 4 As shown, this embodiment includes:

[0030] Hot water pool system, waste heat utilization system and cold water treatment system;

[0031] The hot water tank system includes a distillation furnace unit, a hot water tank unit and a unit driving heat source unit;

[0032] The waste heat utilization system includes a fluid heater unit, a deaerator unit, a gas boiler unit and an electrode boiler unit;

[0033] The cold water treatment system includes cooling tower unit, cold water pool unit, tap water replenishment unit and workshop ice bucket unit;

[0034] The fluid heater unit comprises a fluid heater body 1, a premixing connector 2 is fixedly installed at the top inlet of the fluid heater body 1, and the premixing connector 2 is integrally composed of three inlet pipes at the top, a funnel body in the middle and a transmission pipe at the bottom;

[0035] A rotating motor 3 is fixedly installed on the top of the premixing connector 2, a rotating shaft 4 is fixedly installed on the output end of the rotating motor 3, the rotating shaft 4 penetrates and is rotatably installed on the top of the premixing connector 2, a connecting rod 5 is fixedly installed on the bottom of the rotating shaft 4, a mixing plate 6 is fixedly installed on the bottom of the connecting rod 5, and the mixing plate 6 is slidably installed on the inner side wall of the premixing connector 2;

[0036] The mixing plate 6 is in the shape of a triangular column as a whole and has an arc-shaped top. Trapezoidal notches 7 are provided on the left and right side surfaces of the mixing plate 6. Inclined sliding surfaces 8 are provided on the front and rear side surfaces of the mixing plate 6 to facilitate the flow of water. Arc plates 9 are fixedly installed on the two oblique sides of the trapezoidal notch 7 on the left and right sides of the mixing plate 6.

[0037] In the above technical scheme, the distillation furnace unit condenses the wine vapor from gas to liquid. This process uses cooling water. After use, the temperature of the cooling water will rise, containing a large amount of heat energy, and finally forming 80°C cooling water return water. The 80°C cooling water return water will enter the hot water tank unit for storage. Part of the hot water will enter the unit driving heat source unit for use as a driving heat source, and the other part of the hot water will be transmitted to the fluid heater unit as boiler feed water. In addition to receiving the boiler feed water from the hot water tank unit, the fluid heater unit will also receive feed water from the gas boiler unit and the electrode boiler unit. The water temperature transmitted from the gas boiler unit is 55°C, and the water temperature transmitted from the electrode boiler unit is 20°C. The heat unit will receive water from three different water temperatures. Finally, the fluid heater unit will mix the water of three different water temperatures and heat it to 75°C, and then transmit it to the deaerator for use. In this way, the waste heat utilization improves the working efficiency of the deaerator and reduces energy waste. The return water generated after the waste heat utilization is cooled by the cooling tower unit and collected in the cold water pool unit. The cold water pool unit also collects the water in the tap water replenishment unit, and finally mixes it to 20°C and transmits it to the ice bucket units of each workshop. By using a fluid heater in the waste heat utilization system, the energy utilization efficiency can be improved, thereby improving the working efficiency of the deaerator, reducing energy consumption, improving the stability and reliability of the system, reducing maintenance costs, and improving the safety of the system.

[0038] Since the fluid heater unit inputs water at three different water temperatures, the temperature change will cause the thermal stress inside the fluid heater to change, which will cause some parts of the heater to deform, crack and other problems due to uneven thermal expansion and contraction, thereby affecting the effect of heat exchange. Therefore, a premixing connector 2 is designed to premix water at different temperatures so that the water temperature entering the heater is relatively stable. The fluid heater can operate under relatively stable working conditions, which can make the heat exchange process inside the fluid heater more stable, and the heat transfer efficiency can be maintained at a high level, thereby improving the overall work efficiency;

[0039] First, water at three different temperatures enters the interior through the inlet pipe of the premixing connector 2, and the rotating motor 3 is started to rotate. The rotating motor 3 drives the rotating shaft 4 to rotate, and the rotating shaft 4 will drive the connecting rod 5 to rotate accordingly. The bottom of the connecting rod 5 will drive the mixing plate 6 to rotate accordingly, and the water entering the premixing connector 2 will be stirred by the mixing plate 6 to produce a mixing effect. While the mixing plate 6 is stirring, the water passing through the side of the mixing plate 6 will move upward along the trapezoidal notch 7. Since the trapezoidal notch 7 is larger at the bottom and smaller at the top, the water flowing along the trapezoidal notch 7 will gradually aggregate, thereby producing a mixing effect, improving the mixing effect of the water near the mixing plate 6, and thereby improving the overall mixing effect of the water. Part of the water flowing to the top of the mixing plate 6 will turn over the mixing plate 6 to continue to participate in subsequent mixing, while part of the water will slide down through the inclined sliding surface 8 to prevent the mixing plate 6 from intercepting the water for a long time and affecting the water temperature. During the flow, due to the thrust generated by the mixing plate 6 following the rotation and the water flowing and aggregating on the trapezoidal groove 7 to generate the mutual squeezing force of the water, the water will be agitated and form an impact on the arc plate 9, and the arc plate 9 will have the effect of preventing the impact and agitation, and the effect of the arc surface of the arc plate 9 can allow the impacted water to return to the trapezoidal groove 7, and it also has the effect of backflow under the effect of preventing the impact and agitation, and the prevention of impact and backflow is equivalent to forming a secondary stirring and mixing, thereby improving the mixing effect of the water on the trapezoidal groove 7, thereby improving the overall mixing effect, and making the water temperature mixing faster, and finally, by providing a mixing plate 6, the rotation of the mixing plate 6 is utilized to mix and stir water of different temperatures, and at the same time, the trapezoidal groove 7 and the arc plate 9 are utilized to prevent impact and backflow to form a secondary stirring effect, thereby improving the mixing effect, so as to make the water temperature mixing faster and improve the overall work efficiency.

[0040] In summary, by providing a fluid accelerator, the energy utilization efficiency can be improved, thereby improving the working efficiency of the deaerator and reducing energy consumption, and a premixing connector 2 is added to the fluid accelerator, and the incoming water of different temperatures is fully premixed through the mixing plate 6, the trapezoidal notch 7 and the arc plate 9, so that the fluid heater can operate under relatively stable working conditions. This can make the heat exchange process inside the fluid heater more stable, and the heat transfer efficiency can be maintained at a high level, thereby improving the overall working efficiency.
