Description

Technical Field

[0001] This utility model relates to the field of high-efficiency and energy-saving MVR evaporation technology, specifically to a high-efficiency and energy-saving MVR evaporator for water pollution treatment. Background Technology

[0002] MVR evaporators are highly efficient and energy-saving evaporation devices. Their core principle is to use a mechanical compressor to compress the secondary steam generated during the evaporation process, increasing its pressure and temperature, so that it can be recycled as heating steam, thereby significantly reducing dependence on external energy sources.

[0003] In the use of high-efficiency and energy-saving MVR evaporators for water pollution treatment, the raw liquid first enters the evaporator and then flows downward from the top of the inner wall of the heat exchange tube. At this time, the raw liquid forms a liquid film inside the heat exchange tube. During the flow, the heating steam outside the heat exchange tube heats the liquid film inside the tube, causing it to boil and evaporate as it flows downward. The secondary steam generated by evaporation is compressed and sent back into the heating chamber as heating steam, thereby achieving efficient recycling of thermal energy. In contrast, the inlet of the heat exchange tube in traditional high-efficiency and energy-saving MVR evaporators is recessed, which causes uneven mass of raw liquid flowing into the inner and outer heat exchange tubes, resulting in a decrease in falling film evaporation efficiency.

[0004] Therefore, a solution is proposed based on a high-efficiency and energy-saving MVR evaporator for water pollution control to address the problems mentioned above. Utility Model Content

[0024] 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. Example:

[0025] Please see Figure 1 - Figure 5 The high-efficiency and energy-saving MVR evaporator for water pollution treatment in this embodiment includes a shell 1 and a feed pipe 2 fixedly disposed on the upper surface of the shell 1. The lower end of the feed pipe 2 extends into the interior of the shell 1. A flow buffer outer wall 3 is fixedly disposed below the feed pipe 2. A flow buffer inner wall 4 is fixedly disposed inside the flow buffer outer wall 3. A fixing plate 7 is disposed below the flow buffer inner wall 4. The fixing plate 7 is fixedly connected to the shell 1.

[0026] A flow equalization groove 10 is provided on the upper surface of the fixed disk 7. Several arc-shaped rings 11 are fixedly installed on the lower surface inside the flow equalization groove 10. Several heat exchange tubes 8 are fixedly installed on the lower surface of the fixed disk 7. The heat exchange tubes 8 pass through the fixed disk 7, and the upper end of the heat exchange tubes 8 is fixedly connected to the arc-shaped rings 11.

[0027] Falling film evaporation involves the raw liquid flowing downwards from the top of the inner wall of the heat exchange tube 8. At this time, the raw liquid forms a liquid film inside the heat exchange tube 8. During the flow, heating steam is used to heat the liquid film inside the tube. This utility model only describes the part of the raw liquid entering the heat exchange tube. Since the other parts are existing known technologies in related fields, they are not described in detail in this embodiment.

[0028] The raw liquid enters the interior of the outer shell 1 through the feed pipe 2. Based on the connection between the feed pipe 2 and the outer wall 3 of the flow buffer, the raw liquid enters the interior of the outer wall 3 of the flow buffer. The inner wall 4 of the flow buffer is fixedly installed inside the outer wall 3 of the flow buffer. The raw liquid impacts the surface of the inner wall 4 of the flow buffer, at which point the flow rate of the raw liquid decreases, causing the raw liquid to flow downward along the surface of the inner wall 4 of the flow buffer. The raw liquid flows downward within the flow buffer cavity 9 formed by the inner wall 4 and the outer wall 3 of the flow buffer, allowing the raw liquid to flow smoothly into the flow equalization groove 1 on the upper surface of the fixed plate 7. 0, causing the stock solution to rise in the plane within the equalization tank 10. Based on the fact that the upper ends of all the arc-shaped rings 11 are at the same height, after the stock solution plane rises to the upper surface of the arc-shaped rings 11, the stock solution flows into the interior of all the arc-shaped rings 11 simultaneously. Based on the connection between the arc-shaped rings 11 and the heat exchange tubes 8, the stock solution flows into the interior of the heat exchange tubes 8. Through the setting of the arc-shaped rings 11, the stock solution reaches a certain height within the equalization tank 10 and flows into the interior of all the arc-shaped rings 11 simultaneously, achieving the effect of the stock solution flowing evenly into the inner and outer heat exchange tubes 8.

[0029] A fixing ring 13 is fixedly installed at the center of the upper surface of the outer wall 3 of the flow buffer. The lower end of the feed pipe 2 is inserted into the inside of the fixing ring 13, and the feed pipe 2 penetrates the inner and outer surfaces of the outer wall 3 of the flow buffer.

[0030] The upper surface of the inner wall 4 of the flow regulator is provided with a flow regulating groove 6. The flow regulating groove 6 is set in an arc shape, and the connection between the edge of the flow regulating groove 6 and the upper surface of the inner wall 4 of the flow regulator is a smooth arc shape.

[0031] At least three fixing blocks 5 are fixedly installed on the upper surface of the inner wall 4 of the flow buffer. The end of the fixing block 5 away from the inner wall 4 of the flow buffer is fixedly connected to the inner surface of the outer wall 3 of the flow buffer.

[0032] The inner surface of the outer wall 3 of the flow regulator and the outer surface of the inner wall 4 of the flow regulator form a flow-regulating cavity 9, and the lower end of the flow-regulating cavity 9 is a narrow annular structure.

[0033] The raw liquid enters the interior of the outer shell 1 through the feed pipe 2. The lower end of the feed pipe 2 is inserted into the fixed ring 13, and the feed pipe 2 penetrates the inner and outer surfaces of the outer wall 3 of the slower. The raw liquid flows into the interior of the outer wall 3 of the slower through the feed pipe 2, and impacts the slowing groove 6 on the upper surface of the inner wall 4 of the slower. Based on the arc-shaped design of the slowing groove 6 itself, and the smooth arc-shaped connection between the edge of the slowing groove 6 and the upper surface of the inner wall 4 of the slower, the raw liquid moves along the surface of the slowing groove 6, and the slowing groove 6 reduces the impact force of the raw liquid. The raw liquid moves downward along the surface of the inner wall 4 of the slower, and flows into the slowing cavity 9 formed by the outer wall 3 and the inner wall 4 of the slower. Based on the narrow setting of the slowing cavity 9, the flow rate of the raw liquid is further reduced, and the raw liquid flows smoothly into the equalization groove 10 on the upper surface of the fixed plate 7.

[0034] Based on the fixed connection between the inner wall 4 of the flow buffer and the fixing block 5, and the fixed connection between the fixing block 5 and the outer wall 3 of the flow buffer, the relative positions of the inner wall 4 and the outer wall 3 of the flow buffer are fixed. The fixing block 5 is flat, so that it will not affect the flow of the original liquid. Based on the fixed connection between the outer wall 3 of the flow buffer and the fixing ring 13, the relative positions of the outer wall 3 and the fixing ring 13 are fixed. During installation, the heat exchange tube 8 is directly inserted into the inside of the fixing ring 13, so that the position of the fixing ring 13 is fixed, thereby fixing the positions of the outer wall 3 and the inner wall 4 of the flow buffer.

[0035] The fixed plate 7 is located directly below the inner wall 4 of the flow buffer, and the arc-shaped ring 11 is located directly below the inner side of the inner wall 4 of the flow buffer.

[0036] Arc-shaped rings 11 are evenly distributed on the lower surface of the flow equalization groove 10, and the connection between the outer surface of the arc-shaped rings 11 and the flow equalization groove 10 is a smooth, recessed arc shape.

[0037] A conical surface 12 is provided on the inner side of the arc-shaped ring 11, and the lower end of the conical surface 12 is smoothly connected to the inner wall of the upper end of the heat exchange tube 8.

[0038] The arc-shaped ring 11 is located directly below the inner side of the inner wall 4 of the flow buffer, so that the raw liquid will not flow directly into the arc-shaped ring 11 when it flows down along the flow buffer 9. Based on the smooth and recessed arc-shaped setting at the connection between the arc-shaped ring 11 and the flow equalization tank 10, the raw liquid will not be blocked when it rises, and the upper plane of the raw liquid inside the flow equalization tank 10 will always be consistent. When the raw liquid flows into the arc-shaped ring 11, based on the setting of the conical surface 12, the raw liquid forms a water film on the surface of the conical surface 12, so that the raw liquid enters the heat exchange tube 8 in the state of water film, and forms a liquid film on the inner wall of the heat exchange tube 8.

[0039] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
