Description

Technical Field

[0001] This utility model relates to the field of evaporator technology, specifically to a high-efficiency, high-thermal-conductivity evaporator for wastewater treatment. Background Technology

[0002] With rapid industrialization, wastewater treatment has become an increasingly serious problem, especially the treatment of high-concentration organic wastewater, heavy metal wastewater, and high-salinity wastewater. Traditional methods (such as biological treatment and chemical precipitation) are often inefficient, costly, or fail to meet standards. Evaporation and concentration technology has been widely used in the field of wastewater treatment due to its advantages such as high efficiency and strong adaptability. However, the performance of its core equipment, the evaporator, directly affects the treatment efficiency and energy consumption.

[0003] Chinese utility model patent CN222729529U discloses a high thermal conductivity wastewater evaporator, but its design still has the following drawbacks:

[0004] 1. Although the design of hollow spheres and corrugated gaps improves the steam dispersion efficiency, relying solely on a single steam inlet pipe may result in uneven steam distribution within the evaporator body, especially in areas far from the inlet where preheating is slower.

[0005] 2. The openings of the uniformly distributed plate are fixed and densely distributed. If the wastewater contains suspended solids, it is easy to clog and cannot adapt to different flow requirements.

[0006] Therefore, we propose a high-efficiency, high-thermal-conductivity evaporator for wastewater treatment to address the aforementioned problems. Utility Model Content

[0007] The purpose of this invention is to provide a high-efficiency, high-thermal-conductivity evaporator for wastewater treatment, in order to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A high-efficiency, high-thermal-conductivity evaporator for wastewater treatment includes a shell, a feed section, a rotating assembly, an adjusting assembly, and a filtering assembly. The shell contains multiple straight tubes, and its outer surface is respectively provided with a steam inlet, an exhaust outlet, and a waste liquid outlet.

[0010] The feeding section is located at the top of the shell, and a liquid guide tube is provided in the middle of the top of the feeding section. Furthermore, a flow guide plate and a distribution plate are respectively provided in the feeding section, with the flow guide plate located above the distribution plate.

[0011] The rotating assembly is disposed between the inner walls of the feed section, and the rotating assembly is meshed and driven with the uniform distribution plate;

[0012] The top of the guide plate is concave, and a through hole is provided in the middle of it. The adjustment component is flexibly disposed in the through hole.

[0013] The filter assembly is disposed between the inner walls of the regulating assembly.

[0014] According to the above technical solution, the rotating component includes a drive gear, which is rotatably disposed between the inner walls of the feed section. A plurality of tooth grooves are evenly opened on the outer circumferential surface of the uniformly distributed plate, and the drive gear meshes between the tooth grooves.

[0015] According to the above technical solution, the adjustment component includes an adjustment member, which is composed of a frustum and a cylindrical part. The frustum is located at the top of the cylindrical part, and the cylindrical part is a hollow structure. The lower surface of the frustum can be adapted to the concave surface of the guide plate. Several through holes are opened on the cylindrical part along its circumference. When the through holes are exposed, the waste liquid can flow out through the through holes and from the bottom of the adjustment member.

[0016] According to the above technical solution, a slider is provided on the outer surface of the adjusting component. The slider slides along the inner wall of the guide plate for adjustment. An adjusting spring is provided below the slider and is always in contact with it. A distance sensor is also embedded on the top surface of the slider.

[0017] According to the above technical solution, the filter assembly includes a filter element, which is installed between the inner walls of the adjusting member by a threaded connection, and a toggle block is also provided on the bottom wall of the filter element.

[0018] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0019] (1) By setting a rotating component on one side of the uniform distribution plate, the uniform distribution plate is driven to rotate by the meshing of gears, so that all the straight tubes installed on the uniform distribution plate can be preheated in close contact with the steam inlet, thereby effectively improving the preheating effect of the straight tubes.

[0020] (2) By setting an adjustment component and a filter component in the middle of the guide plate, the filter component is used to filter the impurity particles in the wastewater, thereby reducing the impurity content in the wastewater. At the same time, the adjustment component controls the flow of wastewater in a flexible manner. When the wastewater cannot flow, the filter component needs to be replaced.

[0027] 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.

[0028] Please see Figure 1-5 The present invention provides the following technical solution:

[0029] A high-efficiency, high-thermal-conductivity evaporator for wastewater treatment includes a shell 1, a feed section 2, a rotating assembly, an adjusting assembly, and a filtering assembly. Multiple straight tubes 5 are distributed inside the shell 1. The straight tubes 5 are arranged vertically, and steam inlet, exhaust outlet, and waste liquid outlet are respectively arranged on the outer surface of the shell 1 in a downward direction.

[0030] The feed section 2 is fixed to the top of the housing 1 by bolts, and a liquid guide tube 21 is fixed to the middle of the top of the feed section 2 by threaded connection. In addition, a guide plate 3 and a uniform distribution plate 4 are respectively provided in the feed section 2. The guide plate 3 is located above the uniform distribution plate 4. The guide plate 3 is fixed to the inner wall of the feed section 2 by bolts. The uniform distribution plate 4 is rotatably set between the inner walls of the feed section 2. Limiting rings are provided on the top and bottom surfaces of the uniform distribution plate 4. The limiting rings are fixed between the inner walls of the feed section 2 by screws. Several evenly distributed mounting holes 41 are opened on the uniform distribution plate 4. The top of the straight tube 5 is installed and fixed in the mounting holes 41 by threaded connection.

[0031] It should be further explained that the wastewater enters the feed section 2 from the liquid guide pipe 21, flows to the uniform distribution plate 4 after being guided by the guide plate 3, and then flows into each of the straight tubes 5 from the uniform distribution plate 4. Before treatment, high-temperature steam is introduced into the shell 1 through the steam inlet to preheat the inside of each of the straight tubes 5. After treatment, the efficiency of wastewater evaporation can be directly improved. The evaporated gas is discharged from the exhaust port, while the generated waste liquid is discharged from the waste liquid outlet.

[0032] The rotating assembly is disposed between the inner walls of the feed section 2 and is meshed with the uniform distribution plate 4 for transmission. The rotating assembly includes a drive gear 22, which is rotatably disposed between the inner walls of the feed section 2. Several toothed grooves 42 are evenly opened on the outer circumferential surface of the uniform distribution plate 4. The drive gear 22 meshes between the toothed grooves 42. A rotary motor is installed on the top surface of the feed section 2 by bolts. The output shaft of the rotary motor is connected to the drive gear 22 and drives it.

[0033] Limiting buckles 23 are also installed between the inner walls of the feeding section 2 by insertion. The limiting buckles 23 are U-shaped and, after assembly, they form a space with the cavity opened in the feeding section 2 for the drive gear 22 to rotate.

[0034] It should be further explained that by starting the rotary motor, it drives the drive gear 22 to rotate. Under the action of the meshing transmission of the drive gear 22, the uniform distribution plate 4 rotates synchronously. Since the straight tubes 5 are installed on the uniform distribution plate 4, the straight tubes 5 can rotate synchronously when the uniform distribution plate 4 rotates. This allows the straight tubes 5 at different positions to have close steam contact with the steam inlet, thereby improving the uniformity of steam preheating.

[0035] The top of the guide plate 3 is concave, and a through hole is provided in the middle. The adjustment component is flexibly disposed in the through hole. A vertical groove is provided on one side of the through hole of the guide plate 3 along its height direction. The adjustment component includes an adjustment member 31, which is composed of a frustum and a cylindrical part. The frustum is located at the top of the cylindrical part, and the cylindrical part is a hollow structure. The lower surface of the frustum can be adapted to the concave surface of the guide plate 3. Several through holes are provided on the cylindrical part along its circumference. When the through holes are exposed, the waste liquid can flow out through the through holes and from the bottom of the adjustment member 31.

[0036] A slider 32 is provided on the outer surface of the adjusting component 31. The slider 32 slides along the inner wall of the vertical groove for adjustment. A guide rod 33 is also fixed in the vertical groove along its height direction. An adjusting spring is provided below the slider 32 and is always in contact with it. The adjusting spring is sleeved on the guide rod 33. A distance sensor (not shown in the figure) is also embedded on the top surface of the slider 32. The distance sensor detects the distance between the top surface of the slider 32 and the top surface of the vertical groove.

[0037] It should be further explained that when wastewater enters the feed section 2 from the liquid guide pipe 21 and falls onto the guide plate 3, the wastewater flows along the concave surface of the frustum and flows out from the bottom of the through hole in the middle. In the early stage of treatment, there are not many impurity particles filtered in the wastewater, so the downward force generated by the wastewater flowing downward from the regulating member 31 is not enough to move the entire regulating member 31 to fit the frustum with the concave surface of the guide plate 3. Therefore, during this process, the through hole always has an exposed part for the wastewater to pass through. As the treatment time continues to extend, the impurity particles blocked in the wastewater gradually increase and accumulate in the filter element 34, thereby increasing the weight of the filter element 34 (and indirectly increasing the total weight of the regulating member 31). Then, when the downward force generated by the wastewater flowing downward from the regulating member 31 is sufficient to move the entire regulating member 31 to fit the frustum with the concave surface of the guide plate 3, the distance sensor is triggered. At this time, the filter element 34 needs to be cleaned and replaced before it can be used again.

[0038] The filter assembly is disposed between the inner walls of the regulating component. The filter assembly includes a filter element 34, which is installed between the inner walls of the regulating component 31 by means of a threaded connection. A toggle block is also threadedly connected to the bottom wall of the filter element 34.

[0039] It should be further explained that the filter element 34 is used as the medium for filtering impurity particles in the wastewater, so that the filtered impurity particles are blocked inside the filter element 34 until it needs to be cleaned and replaced. When it is removed, the filter element 34 is removed from the bottom of the adjusting member 31. When removing it, hold the toggle block and rotate the filter element 34 outward from the adjusting member 31 so that it gradually separates from the adjusting member 31.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
