Description

Technical Field

[0001] The utility model relates to the technical field of separator inner wall cleaning, in particular to a separator inner wall cleaning structure of an MVR evaporator. Background Art

[0002] The separator of the MVR evaporator refers to the component or device that separates steam and liquid in the MVR evaporator. The MVR evaporator is an energy-saving and environmentally friendly evaporation equipment that improves the energy utilization efficiency in the evaporation process by recompressing steam. During the MVR evaporation process, water is evaporated and easily forms scale and sediment. These sediments may adhere to the inner wall of the separator, affecting the normal operation of the equipment and may cause a decrease in heat transfer efficiency.

[0003] In the prior art, when cleaning the inner wall of the separator, a large amount of acid cleaning and flushing is used to clean the dirt on the inner wall of the separator. This cleaning method not only consumes a large amount of cleaning liquid, but also produces wastewater and waste liquid due to the large amount of acid cleaning agent, which may contain chemical substances harmful to the environment and cause environmental pollution.

[0004] Therefore, we propose a separator inner wall cleaning structure for an MVR evaporator. Utility Model Content

[0012] Beneficial Effects

[0013] The utility model provides a separator inner wall cleaning structure for an MVR evaporator, which has the following beneficial effects:

[0014] (1) The separator inner wall cleaning structure of the MVR evaporator can form a smaller annular space by setting a cleaning tank, and the space is filled with an acidic cleaning liquid to clean the separator inner wall. Such a setting does not require a large amount of cleaning liquid for cleaning and the cleaning liquid will not splash, thereby achieving efficient, accurate, low-pollution and low-cost cleaning.

[0015] (2) The separator inner wall cleaning structure of the MVR evaporator, when in use, the acidic cleaning liquid flows inside the cleaning tank to generate an impact force on the brush assembly.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1: A separator inner wall cleaning structure of an MVR evaporator, such as Figures 1 to 5 As shown, it includes a support base 1 and a separator tank body 2 fixed on the upper end of the support base 1, a cleaning assembly 3 is arranged at the upper end opening of the separator tank body 2, and the cleaning assembly 3 includes a group of head connecting pieces 31, a group of tail connecting pieces 33 and four groups of intermediate connecting pieces 32, the head connecting piece 31 and the tail connecting piece 33 are arranged adjacent to each other, one end of the head connecting piece 31 away from the tail connecting piece 33 is connected to the other end of the tail connecting piece 33 through the four groups of intermediate connecting pieces 32, the head connecting piece 31, the tail connecting piece 33 and the intermediate connecting piece 32 are all detachably connected to the components at the adjacent positions through the snap-fit ​​structure, and the head connecting piece 31, the tail connecting piece 33 and the intermediate connecting piece 32 are connected to each other. After being connected, an annular structure is formed, and cleaning grooves 4 are opened on the outer wall surfaces of the head connecting piece 31, the tail connecting piece 33 and the middle connecting piece 32. All the cleaning grooves 4 are connected head to tail to form an annular groove. An isolation plate 5 is fixedly connected to the side of the cleaning groove 4 of the head connecting piece 31 close to the tail connecting piece 33 to isolate the head connecting piece 31 from the cleaning groove 4 in the tail connecting piece 33. A water inlet pipe 7 for conveying liquid to the inside of the cleaning groove 4 of the head connecting piece 31 is connected to the top of the head connecting piece 31 near the isolation plate 5. A water outlet pipe 8 for draining water to the outside is connected to the bottom of the tail connecting piece 33 near the isolation plate 5. Brush assemblies 6 are arranged inside all the cleaning grooves 4.

[0027] When in use, the head connector 31, the tail connector 33 and the middle connector 32 are assembled in sequence to form a cleaning assembly 3, and the annular cleaning assembly 3 is horizontally placed inside the separator tank body 2. At this time, the annular groove formed by all the cleaning grooves 4 together contacts the inner surface of the separator tank body 2. At this time, acidic cleaning liquid is injected into the cleaning groove 4 through the water inlet pipe 7. Due to the obstruction of the isolation plate 5, the acidic cleaning liquid can only flow counterclockwise inside the cleaning groove 4. When the cleaning liquid fills the cleaning groove 4 and is discharged outwardly through the water outlet pipe 8, the entire cleaning assembly 3 is slowly moved up and down by hand when the acidic cleaning liquid flows inside the cleaning groove 4, and the brush assembly 6 cooperates with the cleaning liquid to clean the inner wall of the separator. By setting the cleaning groove 4, a smaller annular space can be formed, and the space is filled with acidic cleaning liquid to clean the inner wall of the separator. Such a setting does not require a large amount of cleaning liquid for cleaning and the cleaning liquid will not splash, thereby achieving efficient, accurate, low-pollution and low-cost cleaning.

[0028] Embodiment 2: Based on the above embodiment, Figure 2As shown, sealing rings 11 are connected to the edges of the outer sides of the head connector 31, the middle connector 32 and the tail connector 33 near the cleaning tank 4. The sealing rings 11 can further improve the sealing performance at the edges of the cleaning tank 4, and the sealing rings 11 made of soft material can wipe the positions where the entire cleaning component 3 moves vertically to prevent residual cleaning liquid on the inner wall of the evaporator.

[0029] Embodiment 3: Based on the above embodiment, Figures 2 to 4 As shown, the left side walls of the head connecting member 31, the middle connecting member 32 and the tail connecting member 33 are fixedly connected with a pin 10, and the right side walls of the head connecting member 31, the middle connecting member 32 and the tail connecting member 33 are provided with a slot 9 that is translationally engaged with the pin 10. The head connecting member 31, the middle connecting member 32 and the tail connecting member 33 are engaged and connected by the pin 10 and the slot 9 on both sides.

[0030] Embodiment 4: Based on the above embodiment, Figure 5 As shown, the brush assembly 6 includes a rotating shaft 61, a rotating disk 62 and a brush head 63. The rotating shaft 61 is a cylindrical rod and is fixed on the inner wall of the cleaning tank 4. The rotating shaft 61 is connected to the center position of the rotating disk 62. The brush head 63 is fixed on the side of the rotating disk 62 away from the rotating shaft 61. The rotating shaft 61 and the rotating disk 62 are movably connected at the center position.

[0031] When in use, the acidic cleaning liquid flows inside the cleaning tank 4 and generates an impact force on the brush assembly 6. Under the action of the impact force, the turntable 62 rotates and drives the brush head 63 to rotate, thereby increasing the contact force between the brush head 63 and the cleaning surface and improving the cleaning efficiency. At the same time, it can also reduce the wear of the brush head 63 in a single direction and extend the service life of the brush head 63.
