Description

Technical Field

[0001] This utility model relates to the field of distillation and purification technology, specifically to a double distillation purification device. Background Technology

[0002] Distillation is a common method for obtaining high-purity liquids. Existing distillation purification equipment typically requires heating the entire furnace of liquid to be purified from room temperature to boiling. According to the heat formula Q1=CmΔT, this preheating process is time-consuming and consumes a large amount of electrical energy, resulting in low overall heat conversion efficiency and energy waste. Furthermore, during long-term use, the surface of the heating elements inside the steam furnace easily accumulates scale and other dirt due to repeated heating. This not only further reduces heat conversion efficiency but also corrodes the heating elements, shortening the equipment's lifespan and increasing after-sales maintenance costs. Therefore, users need to frequently clean and maintain the equipment, leading to a poor user experience.

[0003] Improving the energy utilization and purification efficiency of the distillation process, while extending equipment life and reducing maintenance frequency, is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a double distillation purification device, which aims to solve the problems of low energy utilization, long purification time, short service life and inconvenient maintenance of the existing distillation purification device.

[0005] This utility model is achieved through the following technical solution: This utility model discloses a double distillation purification device, which includes a steam furnace, a heating device, a liquid replenishment device, and a control module. The steam furnace is equipped with a preheating inner tank and at least one liquid level sensor. The heating device heats the steam furnace. The liquid replenishment device is used to replenish the liquid to be purified into the preheating inner tank. The control module is signal-connected to the liquid level sensor, the heating device, and the liquid replenishment device. The liquid replenishment outlet of the liquid replenishment device is connected to the lower part of the preheating inner tank. When the liquid to be purified is added to its interior, it can overflow from the top of the preheated inner tank into the steam furnace.

[0006] Furthermore, the liquid level sensor is divided into an upper liquid level sensor and a low liquid level sensor; The control module is configured to activate the liquid replenishment device when the low liquid level sensor does not detect a liquid level, and to deactivate the liquid replenishment device when the upper liquid level sensor detects a liquid level.

[0007] Furthermore, the volume of the steam furnace corresponding to the upper liquid level sensor and the lower liquid level sensor is smaller than the volume of the preheating inner liner.

[0008] Furthermore, it also includes a steam condensation device and a water storage device for storing the purified liquid; the steam condensation device is connected to the steam outlet of the steam furnace and transports the condensed purified liquid to the water storage device.

[0009] Furthermore, the steam condensation device is equipped with a temperature sensor; the control module is also electrically connected to the temperature sensor and is configured to stop all operations of the purification device when it receives an abnormal temperature signal from the temperature sensor.

[0010] Furthermore, the water storage device is equipped with a full liquid sensor and a low liquid sensor; the control module is configured to stop the device from working and enter a standby state when it receives a signal from the full liquid sensor, and to start the purification process when it receives a signal from the low liquid sensor.

[0011] Furthermore, a drain outlet is also connected to the bottom of the steam furnace.

[0012] The beneficial effects of this utility model are: This utility model discloses a double distillation purification device. By setting a unique preheating inner tank, the newly added liquid to be purified is preheated to a high temperature before entering the main body of the steam furnace. This eliminates the time and energy required to heat the liquid from room temperature to boiling, thereby accelerating the single distillation speed and saving electrical energy, significantly improving distillation efficiency and energy utilization. In addition, the entire purification process is automatically controlled by the control module based on signals from various sensors, realizing automatic start-up when the liquid is low, automatic stop-up when the liquid is full, and fault self-diagnosis, without the need for manual intervention. At the same time, it reduces the accumulation of dirt in the furnace caused by frequent repeated heating, reduces the frequency of cleaning and maintenance for users, and improves the user experience.

Detailed Implementation

[0016] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0017] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0018] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0019] like Figure 1 As shown, this embodiment discloses a double distillation purification device, which includes a control module, a steam furnace 101, a liquid replenishment device 104, a steam condensation device 107, and a water storage device 108.

[0020] The steam furnace 101 is the core component of this device, and it is equipped with a heating device 103 for heating the liquid. The steam furnace 101 is also equipped with an upper liquid level sensor 105 and a low liquid level sensor 106 for real-time monitoring of the liquid level inside the furnace.

[0021] Specifically, in this embodiment, the steam furnace 101 is also equipped with a preheating inner liner 102. For example... Figure 1As shown, the inlet of the liquid replenishment device 104 is connected to the bottom of the preheating inner tank 102. When the liquid replenishment device 104 is working, the room temperature liquid to be purified enters from the bottom of the preheating inner tank 102. Since the inner tank is surrounded by the high temperature liquid in the steam furnace 101, the entering liquid is rapidly heated during its ascent. When the preheating inner tank 102 is full, the liquid that has reached a high temperature will overflow from the opening at its top and replenish the main space of the steam furnace 101.

[0022] The principle behind this design lies in its ingenious use of the heat from the steam furnace 101 itself to preheat the replenishing liquid. In traditional distillation processes, heat energy consumption is divided into two parts: the heat required to heat water from room temperature to 100°C (Q1) and the heat required to vaporize the water at 100°C (Q2). This invention eliminates the heating process of part Q1 each time liquid is replenished, allowing for direct vaporization. This improves both the speed and energy efficiency of a single distillation by approximately 12.9%.

[0023] To further maximize distillation efficiency, the structural design of this device ensures that the volume between the upper and lower liquid level sensors of the steam furnace 101 is smaller than the volume of the preheating inner liner 102. This ensures that each replenishment of preheated high-temperature liquid is sufficient to quickly restore the liquid level and temperature within the steam furnace 101 to its operating state, thereby enabling continuous and stable steam generation and preventing steam interruptions caused by replenishing cold liquid.

[0024] In addition, to improve the durability and long-term operating efficiency of the device, the inner metal surface of the steam furnace 101 is coated with a corrosion-resistant coating with high hardness and low coefficient of friction (0.04-0.1). This coating can greatly reduce the adhesion of scale and other dirt to the furnace wall and the surface of the heating element 103. Its beneficial effect is to maintain a high heat conversion rate for a long time and significantly extend the service life of the equipment.

[0025] In addition, a drain port 111 is connected to the bottom of the steam furnace 101, and a valve can be installed on the drain port 111. During the distillation process, water continuously vaporizes, while non-volatile impurities such as minerals and salts in the liquid to be purified remain and concentrate at the bottom of the steam furnace, eventually forming scale or sludge. Scale is a poor conductor of heat, and its adhesion to the surface of the heating element severely hinders heat transfer to the liquid. By periodically or as needed opening this drain port 111, these high-concentration residual liquids and precipitated scale can be discharged from the furnace, avoiding the risk of localized overheating and maintaining the high heat conversion efficiency of the heating element, thus fundamentally ensuring the high efficiency of the distillation process.

[0026] Furthermore, the steam condensing device 107 is connected to the steam outlet of the steam furnace 101 via a pipe, and is equipped with a temperature sensor for condensing high-temperature steam into purified liquid. The water storage device 108 is used to collect and store the purified liquid from the condensing device, and is also equipped with a liquid level sensor (water level signal 1-4) for detecting whether the liquid is full or empty.

[0027] The control module is the brain of the entire device. It is connected to all the aforementioned sensors (liquid level, temperature) and actuators (heating device 103, liquid replenishment device 104) and automatically controls the entire purification process according to the preset program and the real-time signals fed back by the sensors.

[0028] In summary, the double distillation purification device of this embodiment, by setting a unique preheating inner tank 102, ensures that the newly added liquid to be purified is preheated to a high temperature before entering the main body of the steam furnace 101, eliminating the time and energy consumption required to heat the liquid from room temperature to boiling, thereby accelerating the single distillation speed and saving electrical energy, significantly improving distillation efficiency and energy utilization. In addition, the entire purification process is automatically controlled by the control module based on signals from various sensors, realizing automatic start-up when liquid is low, automatic stop-up when liquid is full, and fault self-diagnosis, without the need for manual intervention. At the same time, reducing frequent repeated heating also reduces the accumulation of dirt inside the furnace, lowering the frequency of cleaning and maintenance for users and improving the user experience.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
