Abstract
Description
Technical Field
[0001] This utility model relates to the field of brine separation technology, specifically a device for heating, separating, and purifying high-concentration brine wastewater. Background Technology
[0002] In the field of advanced purification treatment of complex waste liquids with low to medium radioactivity and wastewater with high concentration of salinity, since such waste liquids not only contain high concentrations of salt, but also some contain radioactive nuclides (such as fluorine, beryllium, etc.), evaporation and concentration technology has become one of the core links in the advanced purification of such waste liquids because it can reduce the volume of waste liquid and fix nuclides through solid-liquid separation.
[0003] Existing evaporation and concentration devices suffer from two core problems: First, most employ a single heating method. Resistance heating is slow, has high heat loss, and uneven heating at the bottom of the tank easily leads to scale buildup. Steam heating requires auxiliary equipment, is complex, energy-intensive, and unsuitable for the compact layout of radioactive waste treatment. While electromagnetic induction heating offers high heating efficiency, it lacks synergy with other heating methods, making it difficult to balance rapid and uniform heating. Furthermore, traditional devices have simple sealing structures, making them prone to radioactive vapor leakage and failing to meet safety standards for treating low- to medium-level radioactive waste. Second, they suffer from poor capacity adaptability and insufficient system synergy. Most devices are designed for single capacity, requiring equipment replacement for alternating scenarios of large-volume batch processing and small-volume precision processing, increasing costs, space requirements, and extending processing cycles. Additionally, key parameter monitoring is often handled by independent modules, lacking intelligent linkage control with heating, negative pressure, and condensation systems. This leads to parameter fluctuations affecting concentration results and even causing equipment failure.
[0004] Therefore, there is an urgent need for a heating, separation, and purification treatment device for complex waste liquids with low to medium radioactivity and high-concentration saline wastewater that balances heating efficiency, processing flexibility, and safe sealing.

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0046] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example 1
[0047] Please see Figure 1-7 This utility model provides a technical solution:
[0048] like Figure 1 As shown, the high-concentration saline wastewater heating, separation, and purification treatment device provided by this utility model includes a multi-layer support frame 2, a first electromagnetic induction coupling heating device, an electrical control system, a condensation device 1, and a vacuum system. The first electromagnetic induction coupling heating device includes a first feeding tank 4, a first electromagnetic induction heating jacket, and a first resistance heating component 3. Figure 3 As shown, the first electromagnetic induction heating sleeve is installed on the upper part of the multi-layer support frame 2. The internal heating cavity enclosed by the first electromagnetic induction heating sleeve is a cavity that matches the external structure of the first feeding barrel 4, which can realize the all-round wrapping and heating of the feeding barrel.
[0049] like Figure 4As shown, the first electromagnetic induction heating jacket comprises an electromagnetic induction coil 6, a heating furnace outer shell 7, and a heating furnace lining 8. The electromagnetic induction coil 6 is wound and distributed on the outer side wall of the heating furnace lining 8, enabling rapid induction heating of the body of the first feeding barrel 4. The heating furnace outer shell 7 is fitted over the electromagnetic induction coil 6; multiple infrared temperature sensors are installed on the outer side wall of the heating furnace lining 8 to monitor the temperature of the heating jacket area in real time and prevent local overheating.
[0050] A first sealing cover 5, matching the top opening of the first feeding tank 4, is located on the upper part of the multi-layer support frame 2 at the top of the first electromagnetic induction heating jacket. Its bottom opening is the feeding tank inlet. The first sealing cover 5 is fixed to the multi-layer support frame 2 at the top of the heating furnace shell 7. A first lifting module 14 and a sensor assembly are also connected to the multi-layer support frame 2 surrounding the first sealing cover 5. The sensor assembly is connected to the electrical control system and includes a liquid level sensor, a temperature and pressure transmitter, and an infrared temperature sensor. It can collect real-time data on the liquid level, chamber temperature and pressure, and temperature, providing a basis for intelligent system control. An exhaust port is also provided on the first sealing cover 5 to discharge the steam generated during heating. The exhaust port is connected to the condensing device 1 via a high-temperature resistant pipe.
[0051] like Figures 3 to 5 As shown, the bottom of the first feeding bucket 4 is mounted on the first resistance heating assembly 3. The first resistance heating assembly 3 includes a resistance wire, a resistance furnace base 9, a heating guard plate, and a tray 10. The resistance wire is located inside the resistance furnace base 9, and its heating area corresponds to the bottom of the first feeding bucket 4, thus heating the first feeding bucket 4 and solving the problems of uneven heating and salt scale formation at the bottom of the bucket that are easily caused by single induction heating. A heating guard plate is located above the resistance wire and between it and the first feeding bucket 4, which both conducts heat and avoids the safety hazard of direct contact between components. The resistance furnace base 9 is fixed on the tray 10 and is slidably connected to the multi-layer support frame 2 below the first electromagnetic induction heating sleeve via a bucket transport lifting device. Example 2
[0052] like Figure 3As shown, the material barrel transport lifting device includes a horizontal transport mechanism and a screw lifting mechanism 12 installed on the multi-layer support frame 2. The horizontal transport mechanism and the screw lifting mechanism 12 are arranged perpendicularly. The horizontal transport mechanism includes a horizontal transport roller 11 and a drive chain 13. The first feeding barrel 4 is slidably installed on the transport roller 11 through the first resistance heating component 3 at its bottom. The drive chain 13 is connected to the transport roller 11 for driving the transport roller 11 to move back and forth in the horizontal direction, which facilitates feeding and unloading in the non-heated area. The screw lifting mechanism 12 is set on the vertical frame of the multi-layer support frame 2, and the power output end of the screw lifting mechanism 12 is connected to the pallet 10 for driving the pallet 10 to move up and down in the vertical direction of the multi-layer support frame 2.
[0053] like Figure 1 and Figure 2 As shown, the electrical control system controls the lifting device for transporting the material bucket to move up and down, which in turn drives the first resistance heating component 3 and the first feeding bucket 4 to move up and down synchronously. When moving upward, the first feeding bucket 4 is pushed into the heating chamber of the first electromagnetic induction heating jacket and abuts against the first sealing cover 5, forming a sealed chamber inside the first feeding bucket 4. Combined with the vacuum system device built into the first feeding bucket 4, a sealed vacuum chamber is quickly formed, preventing the leakage of radioactive vapors. When moving downward, the screw lifting mechanism 12 drives the first feeding bucket 4 and the first resistance heating component 3 to move downward synchronously, leaving the electromagnetic heating zone, and then is transferred to the unloading station by the horizontal transport mechanism. Example 3
[0054] like Figure 1 and Figure 2 As shown, a second electromagnetic induction coupling heating device 15, with the same structure as the first electromagnetic induction coupling heating device, is also provided on the multi-layer support frame 2; as shown... Figure 6 As shown, the second electromagnetic induction coupling heating device 15 includes a second feeding barrel heating device 17, a second sealing cover 18, a second feeding barrel, a second electromagnetic induction heating sleeve 19, and a second lifting mechanism. The second lifting mechanism includes a second lifting rotation module 16 and a third lifting support frame. The top of the second sealing cover 18 is fixed on the third lifting support frame, and the second lifting rotation module 16 drives the third lifting support frame and the second sealing cover 18 to move up and down and rotate out of the upper area of the second feeding barrel, making it easy to remove the second feeding barrel. Compared with the fixed installation of the first sealing cover 5, the structure of the second sealing cover 18 can flexibly adapt to second feeding barrels of different heights and different volumes, effectively broadening the application range of the device and improving the overall versatility and compatibility of the equipment. The second sealing cover 18 is equipped with a sensor connected to the electrical control system signal and an exhaust port connected to the condensation device 1. A drying cylinder base is located at the bottom of the second feeding barrel to support the second feeding barrel.
[0055] The condensing device 1 is connected to the exhaust ports of the first sealing cover 5 and the second sealing cover 18 simultaneously via pipelines; it can condense the steam generated by the two heating devices and is also equipped with a liquid storage tank to store the liquid after the condensing device 1 condenses the steam, realizing water resource recovery and compliant treatment of exhaust gas. Both the first feeding tank 4 and the second feeding tank are equipped with vacuum systems, which can lower the boiling point of the waste liquid to improve the evaporation and concentration efficiency, and further enhance the airtightness of the chamber to meet the safety standards for the treatment of low-to-medium radioactive waste liquid.
[0056] like Figure 7 As shown, the working process of the high-concentration saline wastewater heating separation and purification device provided by this utility model is as follows:
[0057] First, when a large volume of waste liquid needs to be treated, the first electromagnetic induction coupling heating device is selected: the first feeding bucket 4 is placed on the resistance furnace base 9 and transported by the conveyor roller 11 to the area below the medium frequency electromagnetic induction heating component. Then, the screw lifting mechanism 12 drives the conveyor roller 11 to rise, so that the first feeding bucket 4 enters the inner cavity of the first electromagnetic induction coupling heating device and is sealed with the first sealing cover 5 to form a closed treatment chamber. At this time, the electrical control system starts the metering pump and quantitatively delivers the waste liquid to be treated temporarily stored in the feeding tank to the first feeding bucket 4 through the feeding pipeline. When the liquid level in the bucket reaches the highest level, the metering pump stops adding liquid. If the liquid level is at the lowest level, the pump continues to add liquid.
[0058] After feeding is completed, the device starts the electromagnetic induction coil 6 and the resistance wire of the resistance heating component 3 to carry out the coordinated heating mode. The electromagnetic induction coil 6 generates an alternating magnetic field to heat the barrel body and the resistance wire supplements the heating of the bottom of the barrel to quickly raise the temperature. At the same time, the vacuum negative pressure system is started to reduce the boiling point of the waste liquid and improve the evaporation efficiency.
[0059] During the heating process, an infrared temperature sensor on the outer shell 7 of the heating furnace monitors the temperature in real time, and the electrical control system maintains a stable processing state by regulating the temperature and pressure inside the tank. The steam generated by the evaporation of waste liquid enters the condensation device 1 through the exhaust port of the first sealing cover 5. The condensation heat exchanger supplied by the cooler condenses the steam into liquid. The condensate flows into the condensate storage tank and is then transported to the subsequent processing via a metering pump. The cooler also cools the medium-frequency heating components.
[0060] Once the waste salt in the feeding tank reaches the maximum salt level, the device continues drying until the moisture content meets the standard. Then, the vacuum pump is stopped, the conveyor roller 11 descends to a safe position and starts operating, transferring the drying tank containing the waste salt to the next process.
[0061] When a small amount of waste liquid needs to be treated, select the second electromagnetic induction coupling heating device 15: manually add the waste liquid to the second feeding tank, and heat the tank body through the second electromagnetic induction heating jacket 19. The steam generated by its evaporation also enters the condensing device 1 through the exhaust port of the second sealing cover 18 to complete condensation. After drying is completed, open the cover of the second feeding tank through the second lifting and rotating module 16, and manually remove the waste salt.
[0062] In summary, the high-concentration saline wastewater heating separation and purification treatment device of this utility model adopts electromagnetic induction and resistance synergistic coupling heating, which effectively improves the uniformity, controllability and temperature rise efficiency of heating; at the same time, it is equipped with two different heating stations, which can adapt to the work needs of automated batch treatment of large-volume waste liquid and manual treatment of small-volume waste liquid, effectively reducing costs and space requirements and shortening the treatment cycle; it can also drive the feeding tank to rise and abut the sealing cover through the lifting device, and quickly form a sealed chamber with the vacuum system of the feeding tank, avoiding the leakage of radioactive vapors and meeting the safety standards for the treatment of medium and low radioactive waste liquid.
[0063] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
