Therefore, they should not be construed as limitations on this utility model.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] An adjustable enthalpy difference compensation device, such as Figure 1 As shown, the system includes an inlet 1, a mist outlet, and a vortex chamber 2. Specifically, the inlet 1 and the mist outlet are located at opposite ends of the vortex chamber 2, forming a complete liquid flow channel. A spiral guide groove 3 is provided on the inner wall of the vortex chamber 2. Its function is to allow the wastewater to form a rotating film within the vortex chamber 2, thus providing a good foundation for the subsequent atomization process. Furthermore, the spiral guide groove 3 gradually narrows from the inlet end to the outlet end of the vortex chamber 2. This design can increase the rotation speed of the liquid and further optimize the atomization effect. At the outlet end of the spiral guide groove 3, a nozzle cavity 4 is provided to atomize the rotating film liquid into fine particles. By setting the nozzle cavity 4, the particles of the rotating film liquid can be further refined, so that the atomized liquid particles can be discharged from the mist outlet more concentratedly, ensuring the atomization effect.

[0025] Specifically, one end of the nozzle cavity 4 is installed on the rotational flow chamber 2 by a rotating connection, and the other end is provided with an adjusting assembly between the rotational flow chamber 2. Specifically, the adjusting assembly includes an adjusting block 6, which is rotatably connected to the outer edge of the nozzle cavity 4. A plurality of embedding grooves 7 are formed on the adjusting block 6 to accommodate the outer edge of the rotational flow chamber 2. The rotational flow chamber 2 and the nozzle cavity 4 are fixed by embedding the outer edge of the rotational flow chamber 2 into the embedding groove 7. By providing the adjusting block 6, the nozzle cavity 4 can be adjusted according to the need, so as to adjust the atomized particle diameter. The operator can deflect the nozzle cavity 4 by embedding the outer edge of the rotational flow chamber 2 into different embedding grooves 7 of the adjusting block 6, so as to change the spray angle and the size of the atomized particles, which can significantly improve the salt analysis efficiency and crystallization time, and optimize the purification effect.

[0026] Further, the nozzle cavity 4 and the rotational flow chamber 2 are also provided with a sealing cover 5. The sealing cover 5 has a folded state and an open state. When the nozzle cavity 4 is tightly fitted with the outer wall of the rotational flow chamber 2, the sealing cover 5 is in the folded state, effectively preventing liquid leakage. When the operator needs to adjust the angle of the nozzle cavity 4, the operator only needs to embed the outer edge of the rotational flow chamber 2 into different embedding grooves 7 to make the nozzle cavity 4 rotate. At this time, the sealing cover 5 also expands. The design of the sealing cover 5 not only improves the sealing performance of the device, but also enhances its reliability and stability, avoiding energy waste and equipment damage caused by liquid leakage. At the same time, the spray angle of the nozzle cavity 4 is 45°-90°, and the diameter of the sprayed atomized particles is controlled within 10-50μm. Such small particle size can ensure effective separation and precipitation of salt, while reducing wear and tear on subsequent equipment.

[0027] The inlet 1 is detachably connected with a filter screen 8. The filter screen 8 is used to filter impurities in the liquid entering the device. A ring groove 9 is formed on the inner wall of the inlet 1 to accommodate the embedding of the filter screen 8, ensuring stable installation of the filter screen 8. The outer wall of the filter screen 8 is provided with a rubber block 10 with a circular arc cross section, which is tightly fitted with the inner wall of the inlet 1, enhancing the sealing performance and effectively preventing impurities from entering the device. When the operator installs the filter screen 8, the operator only needs to press it into the inlet 1. At this time, the rubber block 10 is extruded and deformed. After the rubber block 10 enters the ring groove 9, the rubber block 10 returns to its original state and clamps the filter screen 8 in the inlet 1. The design of the filter screen 8 not only improves the service life of the equipment, but also reduces the maintenance cost. Users can easily replace the filter screen 8 according to their needs.

[0028] The rotational flow chamber 2 and the nozzle cavity 4 are both made of stainless steel material. Stainless steel material has good corrosion resistance and mechanical strength, which can ensure long-term stable operation in harsh working environment, reducing the maintenance frequency and cost of the equipment. In addition, stainless steel material also has good heat conductivity, which helps to improve the heat recovery efficiency.

[0029] In practical application, the device can be flexibly adjusted according to different working conditions, for example, when treating high-viscosity sewage, the operator can adjust the opening and closing degree of the nozzle cavity 4, and the size of the atomized particles can be adjusted to the best state, thereby improving the separation efficiency of salt, and at the same time, the spray angle of the nozzle cavity 4 can be adjusted according to the layout and demand of the equipment, to ensure that the atomized liquid can be uniformly distributed.

[0030] The above only describes the preferred embodiments of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments. Any technical solution falling within the concept of the present application shall fall within the protection scope of the present application. It should be noted that, for ordinary skilled persons in the art, some improvements and refinements without departing from the principles of the present application shall also be considered as falling within the protection scope of the present application.
