Abstract
Description
Technical Field
[0001] This utility model relates to the field of water distiller technology, and in particular to an automatic water shut-off type water distiller. Background Technology
[0002] A water distiller is a device that separates liquids based on their different boiling points. It is widely used in the field of liquid separation. Traditional water distillers typically consist of a distillation tank, a heating device, and a condensation system. However, there are several problems that need to be solved in practical applications. First, the heating efficiency is low and the energy consumption is high. The heating device uses a single heating method for the liquid, resulting in uneven heating of the liquid, which prolongs the distillation time and consumes a lot of electrical energy. Second, the heat carried by the distillate is not effectively recovered and utilized during the condensation process, resulting in energy waste and increased operating costs.
[0003] To address these issues, staff improved the performance of the water distiller by modifying the heating element or optimizing the condenser structure. However, these improvements still have limitations. For example, simply modifying the heating element can increase the heating speed to some extent, but it cannot solve the problem of uneven heating of the liquid. Optimizing the condenser structure can accelerate the condensation speed, but it fails to fully utilize the heat of the distillation fraction. Utility Model Content
[0004] This invention proposes an automatic water shut-off type distillation water apparatus to solve the problems of low heating efficiency and ineffective heat recovery and utilization during distillation condensation in existing distillation water apparatuses.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic water-cut-off type distillation water apparatus, comprising a distillation tank, a storage tank, and a condenser. A liquid level sensor is embedded in the lower end of the inner wall of the distillation tank. A fraction delivery pipe is connected between the top of the distillation tank and the condenser. A heat exchanger is provided on the outside of the fraction delivery pipe. A gas supply device is connected between the gas outlet end of the heat exchanger and the bottom of the inside of the distillation tank. Multiple gas outlets are installed along the length direction on the upper end face of the part of the gas supply device located inside the distillation tank.
[0006] Preferably, the heat exchanger includes a heat exchange jacket disposed outside the distillation conveying pipe, with an inlet pipe connected to one end of the outer wall of the heat exchange jacket and an outlet pipe connected to the other end of the outer wall of the heat exchange jacket.
[0007] Preferably, the inner wall of the heat exchange jacket is fixed with spiral air guide plates along its length.
[0008] Preferably, the air supply component includes a connected air delivery pipe and an air jet pipe, with the air inlet end of the air delivery pipe connected to the air outlet pipe, and the air outlet nozzle mounted on the air jet pipe.
[0009] Preferably, the spacing between two adjacent air outlets gradually increases from the middle to both ends of the plurality of air outlets, and the diameter of the plurality of air outlets decreases sequentially from the middle to both ends.
[0010] Preferably, a water pump is installed on the storage tank via a water pipe, and a delivery pipe connects the outlet of the water pump to the distillation tank.
[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0012] (1) By setting up heat exchange components, the heat energy of high-temperature distillate is recovered. The ambient temperature inert gas flows around the distillate delivery pipe inside the heat exchange jacket and transfers heat with the high-temperature distillate. This not only reduces the distillate temperature and alleviates the workload of the subsequent condenser, saving the energy required for condensation, but also raises the gas temperature. The spiral guide vanes extend the gas flow path and increase the contact time between the gas and the outer wall of the distillate delivery pipe, greatly improving the heat exchange efficiency per unit space.
[0013] (2) Gas is supplied to the liquid to be distilled through the gas outlet of the gas supply unit. The gas agitates the liquid, accelerates the collision and mixing between liquid molecules, and increases the liquid convection speed. Among them, the dense and large diameter middle gas outlet can release a large amount of gas to form a high-intensity bubble group, quickly break the static stratification of the liquid, promote the heat exchange between the middle liquid and the heating source, and avoid local overheating.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1-5 As shown, an automatic water-stopping type distillation apparatus includes a distillation tank 1, a storage tank 2, and a condenser 5. An electric heating element is installed at the bottom of the distillation tank 1. The heating element is made of a nickel-chromium alloy heating wire encased in a 304 stainless steel shell, with a Teflon coating for corrosion resistance and anti-dry-burning properties. The storage tank 2 stores the liquid to be distilled. A water pump 3 is installed on the storage tank 2 via a water pipe. A delivery pipe 4 connects the outlet of the water pump 3 to the distillation tank 1. A liquid level sensor 8 is embedded in the lower inner wall of the distillation tank 1, and a temperature sensor is also installed. A controller is also provided. Both the liquid level sensor 8 and the temperature sensor are electrically connected to the controller. When the liquid level sensor 8 detects that the liquid level inside the distillation tank 1 is below a certain value... When the preset threshold is reached, the electric heating element can be quickly stopped by the controller. The temperature sensor can monitor the liquid temperature in real time, which facilitates the adjustment of the heating intensity of the electric heating element as needed. A fraction conveying pipe 10 is connected between the top of the distillation tank 1 and the condenser 5. The distilled fraction is sent into the condenser 5 through the fraction conveying pipe 10 for condensation and collection. A heat exchanger 7 is provided on the outside of the fraction conveying pipe 10. Inert gas is exchanged through the heat exchanger 7. A gas supply 6 is connected between the gas outlet of the heat exchanger 7 and the bottom of the inside of the distillation tank 1. Multiple gas outlets 9 are installed along the length of the upper end face of the gas supply 6 located inside the distillation tank 1. The gas outlets 9 send gas to the liquid to be distilled, so as to realize the agitation of the liquid to be distilled by gas.
[0023] Among them, see Figures 3-4As shown, the heat exchanger 7 includes a heat exchange jacket 71 disposed outside the fraction conveying pipe 10. An inlet pipe 72 is connected to one end of the outer wall of the heat exchange jacket 71, and an outlet pipe 73 is connected to the other end of the outer wall. A spiral guide vane 74 is fixed along the length of the inner wall of the heat exchange jacket 71. Gas enters the heat exchange jacket 71 through the inlet pipe 72. After entering the heat exchange jacket 71, the ambient temperature gas flows around the outer wall of the fraction conveying pipe 10, forming a heat transfer contact with the high-temperature fraction inside the pipe. Because the high-temperature fraction carries a large amount of heat energy during the conveying process, while the ambient temperature gas has a lower temperature, under the action of thermodynamic laws, heat spontaneously transfers from the high-temperature fraction through the pipe wall of the fraction conveying pipe 10 to the ambient temperature gas, causing the gas temperature to gradually increase. Meanwhile, the temperature of the high-temperature distillate decreases accordingly, and the gas after heat exchange is discharged from the outlet pipe 73 and sent to the gas supply unit 6. After the high-temperature distillate is cooled down, the subsequent condensation process in the condenser 5 becomes simpler. The condenser 5 can complete the condensation work without consuming too much energy, which not only reduces the difficulty of condensation, but also effectively saves energy and improves the operating efficiency of the entire system. The spiral guide vane 74 guides the gas to flow along the spiral path. This design changes the original relatively direct and short-distance flow mode of the gas, greatly extending its flow path. The contact time between the gas and the outer wall of the distillate conveying pipe 10 is significantly increased, and more heat can be fully exchanged, which greatly improves the heat exchange efficiency per unit space.
[0024] See Figures 3-4 As shown, the air supply component 6 includes a connected air supply pipe 61 and a jet pipe 62. The air inlet end of the air supply pipe 61 is connected to the air outlet pipe 73. The air outlet nozzles 9 are installed on the jet pipe 62. The distance between two adjacent air outlet nozzles 9 gradually increases from the middle to the two ends, and the diameter of the multiple air outlet nozzles 9 decreases sequentially from the middle to the two ends. The gas discharged from the air outlet pipe 73 enters the air supply pipe 61 and is then ejected through the multiple air outlet nozzles 9 on the jet pipe 62. The bubbles generated during the gas rise burst and flow, causing collisions and mixing between liquid molecules, which greatly enhances the convection of the liquid. The speed of this convection allows heat to be rapidly transferred from the heating source to every corner of the liquid, making the liquid to be distilled more evenly heated and thus achieving a faster heating process. At the same time, the gas discharged from the gas outlet pipe 73 carries a certain temperature. When the warm gas agitates the liquid, it not only plays a physical stirring role but also transfers its own heat directly to the liquid to be distilled through heat transfer. The full contact between the gas and the liquid significantly increases the heat exchange area and accelerates heat conduction, which in turn facilitates the rapid heating of the liquid to be distilled and improves the efficiency and effectiveness of the distillation process.
[0025] In addition, the densely packed air outlets 9 (small spacing and large diameter) can release more gas and form a high-intensity bubble cluster, which can quickly break the static stratification of the central liquid, promote heat exchange between the central liquid and the heating source, and avoid local overheating or uneven heating.
[0026] The central vent 9 has a large diameter, resulting in a lower flow rate but a larger volume of gas. The gas rises slowly in a "bubbling" manner, allowing the bubbles to remain in the liquid for a longer time and release more heat to the liquid through thermal conduction. This design is suitable for scenarios requiring stable temperature rise (such as preheating in the initial stage of distillation).
[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
