Description

Technical Field

[0001] This invention belongs to the field of water treatment and is used for the evaporation of concentrated brine, specifically relating to a simulated solar evaporation device. Background Technology

[0002] With the acceleration of industrialization and the continuous growth of water demand, the treatment of high-salinity wastewater (concentrated brine) has become increasingly prominent. Concentrated brine mainly originates from industries such as chemical, power, metallurgy, and seawater desalination. It has high salt content and complex composition, and direct discharge or improper disposal will cause serious pollution to soil, water bodies, and the ecological environment. Currently, common methods for treating concentrated brine include multi-effect evaporation, mechanical vapor recompression, reverse osmosis, and natural evaporation. However, these methods still have many shortcomings in practical applications. For example, while multi-effect evaporation and mechanical vapor recompression are highly efficient, they consume a lot of energy, have high equipment investment and operating costs, and require strict operating conditions. Reverse osmosis technology is prone to membrane fouling and scaling problems when treating high-salinity wastewater, affecting system stability and service life. Natural evaporation is severely limited by climatic conditions, has a low evaporation rate, requires a large area, and is difficult to meet the needs of continuous, large-scale treatment.

[0003] In recent years, solar evaporation technology has attracted widespread attention due to its green and low-energy characteristics. This technology utilizes solar energy as its energy source, converting light energy into heat energy through photothermal materials to promote water evaporation, thereby reducing the volume of concentrated brine and recovering resources. However, relying entirely on sunlight for evaporation requires a large land area, making practical application difficult. Therefore, there is an urgent need to develop a high-efficiency evaporation device that can simulate sunlight, has a reasonable structure, stable operation, and is easy to maintain, in order to overcome the limitations of natural conditions and achieve rapid, continuous, and energy-efficient treatment of concentrated brine. Summary of the Invention

[0004] To overcome the above-mentioned defects, the purpose of this invention is to provide a simulated solar evaporation device with a smaller footprint, thereby solving the problem of large footprint in existing concentrated brine solar evaporation methods.

[0005] To achieve the above objectives, the simulated solar evaporation device of the present invention includes a cylindrical reactor, with a simulated light source disposed at the center of the reactor; Evaporation material is provided on the side wall of the reactor corresponding to the simulated light source; A water distribution device is provided on the reactor corresponding to the evaporation material.

[0006] Furthermore, a fixing device is also provided inside the reactor corresponding to the evaporation material.

[0007] Furthermore, the fixing device is an evaporation material limiting cage.

[0008] Furthermore, a light-absorbing layer is provided on the side of the evaporation material facing the simulated light source in the reactor; or the surface of the evaporation material is integrally composited with a light-absorbing layer.

[0009] Furthermore, the water distribution device includes a water distribution plate disposed on the reactor, and a plurality of water distribution holes are provided on the water distribution plate corresponding to the evaporation material.

[0010] Furthermore, the water distribution plate is ring-shaped, and the simulated light source is suspended inside the reactor through the middle of the water distribution plate; a vent is formed in the middle of the water distribution plate.

[0011] Furthermore, a water distribution baffle is formed by the upward protrusion of the vent on the water distribution plate.

[0012] Furthermore, the bottom of the reactor is provided with an annular water storage plate; the center of the water storage plate is a vent, and the vent of the water storage plate is convex upward to form a water storage baffle.

[0013] Furthermore, a water level detection device is installed on the water storage baffle.

[0014] The present invention has the following advantages: Highly efficient and stable evaporation: By simulating sunlight tubes to provide continuous and stable illumination, the uncertainty of natural light is overcome, and highly efficient and continuous evaporation of concentrated brine is achieved.

[0015] The structure is reasonably designed: the water distribution plate and the water storage base plate work together to ensure uniform liquid distribution and avoid local drying or water accumulation. At the same time, the water storage base plate can temporarily store unevaporated liquid, which can be reused by the evaporating material through capillary action, thus improving the water resource utilization rate.

[0016] Easy maintenance and material replacement: The design of the evaporation material limiting cage makes it easy to install, fix and replace soft evaporation materials, extending the service life of the device and reducing operation and maintenance costs.

[0017] Excellent ventilation performance: The upper and lower ventilation openings form convection, which effectively promotes the escape of water vapor, maintains a low humidity environment inside the device, and accelerates the evaporation process.

[0018] In summary, this invention has a compact structure, is easy to operate, and has high evaporation efficiency. It is suitable for the treatment and resource utilization of various high-salt wastewaters and has broad application prospects. Attached Figure Description

Detailed Implementation

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

[0024] In the description of this invention, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0025] 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 technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0026] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0027] like Figures 1 to 3 As shown, the cylindrical reactor 11 includes an evaporation zone, a water distribution plate 21, and a water storage bottom plate 31. Concentrated brine is sprayed in through the water distribution plate and evaporates in the evaporation zone. The concentrated brine that has not yet evaporated is temporarily stored in the water storage bottom plate until it is completely evaporated.

[0028] A schematic diagram of the water distribution plate structure is shown below. Figure 2 Several water distribution holes 22 are opened near the edge, and there is a vent 24 in the center. The area around the vent is raised to form a water distribution baffle 23, which is used to prevent water from overflowing.

[0029] The reactor has a water storage plate at the bottom. A vent 34 is located at the center, with the lower vent 34 and upper vent 24 located at the bottom and top of the cylindrical reactor, respectively, facilitating ventilation and promoting the outflow of evaporated water vapor. A water storage baffle 33 is formed around the vent 34 to temporarily accumulate unevaporated concentrated brine. To prevent excessive water distribution and brine overflow, a water level detection device is installed on the water storage baffle 33. When the water level detection device detects that the water level exceeds a predetermined value, the water distribution pipe is closed, stopping water distribution.

[0030] In the evaporation zone, solar evaporation material is placed close to the inner wall of the reactor. Since most evaporation materials are relatively soft and not rigid, they cannot support themselves to adhere to the inner wall. Furthermore, the evaporation materials may need to be replaced frequently and are not suitable for fixing to the inner wall. Therefore, an evaporation material limiting cage 41 is designed to confine the evaporation material between the limiting cage and the inner wall, i.e., the evaporation material zone 42.

[0031] The lamp tube 51 (xenon lamp can be selected) is suspended from the water distribution plate vent into the reactor. The lamp tube emits simulated sunlight to evaporate the concentrated brine.

[0032] The evaporation material should ideally be a hydrophilic porous material. To facilitate effective light absorption, a light-absorbing material layer, such as black mesh or a black transparent or semi-transparent plastic sheet, can be placed on the side facing the lamp tube. Alternatively, an integrated material (such as graphite felt) can be used. The hydrophilic material serves to absorb and store water. If the water distribution speed is too fast, the water distribution should be paused, and excess water should flow into the water storage base. Once the water in the evaporation material has evaporated, it can absorb water from the water storage base through capillary action for further evaporation.

[0033] The present invention has been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the embodiments described above. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Many other changes and modifications made without departing from the concept and scope of the present invention should be considered within the scope of protection of the present invention.

[0034] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0035] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
