Description

Technical Field

[0001] This utility model relates to the field of condensation technology, specifically a self-cleaning and scale-preventing condensation device. Background Technology

[0002] As is well known, scale buildup is the core problem that leads to decreased heat exchange efficiency and increased energy consumption in existing industrial condensing equipment during operation. Traditional anti-scaling technologies mainly rely on mechanical scraping, chemical cleaning or magnetization treatment, but these methods generally have obvious defects.

[0003] Specifically, mechanical scraping requires stopping and disassembling equipment, which not only affects production continuity, but also causes corrosion of pipe walls due to wear and tear of the coating after long-term use. Although chemical pickling can dissolve stubborn scale, the residue of the agent will pollute the cooling water system and pose a risk of corrosion to metal pipes. In addition, most devices rely on periodic manual inspections and cannot dynamically sense the thickness of the scale layer and trigger precise cleaning. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a self-cleaning, scale-preventing, and condensation-preventing device.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a self-cleaning anti-scaling condensation device, comprising a condenser tube, connecting pipes at both ends of the condenser tube, a cavity inside the condenser tube, a sliding component inside the cavity, a cleaning ring outside the sliding component, the cleaning ring being fitted and slidably connected to the inner wall of the cavity, a pulse generator inside the cleaning ring, and a scale monitor on one side of the cleaning ring.

[0008] To ensure stable sliding of the cleaning ring along the axial direction of the condenser tube, the present invention is improved as follows: the sliding assembly includes an electromagnetic slide, an electromagnetic ring, a limiting rod, and a limiting block. The electromagnetic slide and the limiting rod are symmetrically arranged on both sides of the cavity. The electromagnetic ring is on the electromagnetic slide and is electromagnetically slidably connected to it. The limiting block is on the limiting rod and is slidably connected to it. The cleaning ring is connected to the electromagnetic ring and the limiting block.

[0009] To achieve automatic removal of shed scale, the present invention is improved by providing a drain pipe at one end of the condenser tube, and a control valve for controlling the drain pipe is provided on the drain pipe.

[0010] To protect the inner wall coating from scratches, the present invention is improved by having an elastic rubber layer embedded in the cleaning ring and a nano-ceramic coating attached to its surface.

[0011] To monitor scale thickness in real time, the present invention features an improvement: the scale monitor is an ultrasonic probe.

[0012] To ensure the long-term stable operation of the pulse generator, the present invention includes the following improvement: the electrodes of the pulse generator are made of titanium alloy plated with platinum.

[0013] To enhance the physical removal effect of scale, the present invention is improved by uniformly distributing micro-brushes on the outer side of the cleaning ring.

[0014] In order to maintain the low temperature of the cooling water and improve the heat exchange efficiency, the present invention has the following improvements: the condenser tube adopts a double-layer vacuum glass structure, with cooling water flowing in the inner layer and the outer layer being vacuum-insulated.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a self-cleaning anti-scaling condensation device, which has the following beneficial effects:

[0017] This self-cleaning anti-scaling and condensation device is equipped with a cleaning ring and a pulse generator. The micro-brush on the outside of the cleaning ring directly scrapes away the scale adhering to the pipe wall, while the high-frequency pulse wave generated by the pulse generator interferes with the scale crystallization process. It works synergistically from both physical removal and chemical inhibition to significantly improve the anti-scaling effect.

[0018] The scale monitor (ultrasonic probe) detects the scale thickness on the inner wall of the condenser tube in real time. When the scale reaches the preset threshold, the cleaning program is automatically started, avoiding the lag of manual intervention and achieving cleaning on demand.

[0019] The sliding assembly adopts a symmetrical design of electromagnetic slide and limit rod, which allows the cleaning ring to slide stably along the axial direction of the condenser tube, avoiding displacement or jamming, and ensuring that there are no dead corners in the cleaning coverage.

[0020] The cleaning ring has an embedded elastic rubber layer and a nano-ceramic coating, which protects the inner wall of the condenser tube from scratches and reduces friction wear on the cleaning ring itself, thus extending its service life. Attached Figure Description

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.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0028] 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 invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] Please see Figure 1-4 A self-cleaning anti-scaling condensation device includes a condenser tube 1, with connecting pipes 11 at both ends of the condenser tube 1. A cavity is provided inside the condenser tube 1, and a sliding assembly is provided inside the cavity. A cleaning ring 7 is provided on the outer side of the sliding assembly, and the cleaning ring 7 is in contact with and slidably connected to the inner wall of the cavity. A pulse generator 5 is provided inside the cleaning ring 7, and a scale detector 10 is provided on one side of the cleaning ring 7. Micro-brushes are evenly distributed on the outer side of the cleaning ring 7. The scale detector 10 is an ultrasonic probe. A drain pipe 2 is provided at one end of the condenser tube 1, and a control valve 3 is provided on the drain pipe 2 to control the drain pipe 2.

[0030] During use, the connecting pipes 11 at both ends of the condenser tube 1 are connected to the cooling water circulation system (such as industrial equipment or air conditioning refrigeration system), allowing cooling water to flow through the internal cavity of the condenser tube 1 to complete the normal heat exchange task. At this time, the scale monitor 10 (ultrasonic probe) continuously emits high-frequency ultrasonic signals to the inner wall of the condenser tube 1. By receiving the intensity and time difference of the reflected waves, the ultrasonic probe calculates the thickness and distribution of scale on the inner wall in real time. When the scale thickness exceeds a preset threshold (e.g., 0.5 mm), or when uneven scaling occurs in a local area, the monitor sends a signal to the control system to trigger the cleaning program. After receiving the cleaning command, the control system activates the electromagnetic drive function of the sliding component, causing the cleaning ring 7 to reciprocate along the length of the condenser tube 1. During the process, the micro-brushes (made of nylon or carbon fiber) evenly distributed on the outer side of the cleaning ring 7 are closely attached to the inner wall of the condenser tube 1, and the attached scale layer is directly scraped off by mechanical friction. Especially for crystalline hard scale, the pulse generator 5 inside the cleaning ring 7 is activated simultaneously. Its titanium alloy platinum-plated electrode releases high-frequency pulse current in the water, generating periodic pressure waves. The pulse energy interferes with the electrostatic adsorption of calcium and magnesium ions in the water, preventing the detached particles from redepositing. At the same time, the pulse wave forms micro-bubbles in the liquid and collapses instantly, generating local high-pressure shock waves, which further peel off stubborn scale that the brushes have not reached. The scale fragments that are detached during the cleaning process flow into the drain pipe 2 with the cooling water. When the cleaning cycle is completed, the control valve 3 on the drain pipe 2 is opened to discharge the scale-containing wastewater.

[0031] In actual use, it is necessary to ensure that the cleaning ring 7 slides stably along the axial direction of the condenser tube 1 to improve reliability. In order to meet the above requirements, in this embodiment, the sliding assembly includes an electromagnetic slide 4, an electromagnetic ring 6, a limiting rod 8 and a limiting block 9. The electromagnetic slide 4 and the limiting rod 8 are symmetrically arranged on both sides of the cavity. The electromagnetic ring 6 is on the electromagnetic slide 4 and is electromagnetically slidably connected to it. The limiting block 9 is on the limiting rod 8 and is slidably connected to it. The cleaning ring 7 is connected to the electromagnetic ring 6 and the limiting block 9.

[0032] When the electromagnetic slide 4 is energized, it generates a periodic alternating magnetic field distributed along the axial direction. Through electromagnetic induction, it interacts with the electromagnetic coil 6 (embedded permanent magnet or electromagnetic material), pushing the electromagnetic coil 6 to move linearly along the slide. The limiting rod 8 is arranged symmetrically parallel to the electromagnetic slide 4, and the limiting block 9 on it cooperates with the limiting rod 8 to allow only axial sliding and restrict radial offset or rotation. The electromagnetic slide 4 controls the moving direction (forward / backward) and speed of the electromagnetic coil 6 through changes in the magnetic field, providing active driving force.

[0033] In actual use, it is necessary to adaptively fit the pipe wall to protect the inner wall coating from being scratched. In order to meet the above requirements, in this embodiment, the cleaning ring 7 is embedded with an elastic rubber layer and the surface is coated with a nano-ceramic coating.

[0034] In practical use, it is necessary to ensure that the pulse generator 5 works stably for a long time and reduce the frequency of component replacement. In order to meet the above requirements, in this embodiment, the electrodes of the pulse generator 5 are made of titanium alloy plated with platinum.

[0035] In actual use, it is necessary to isolate external heat interference, maintain the low temperature of cooling water, and improve heat exchange efficiency. In order to meet the above requirements, in this embodiment, the condenser tube 1 adopts a double-layer vacuum glass structure, with cooling water flowing in the inner layer and the outer layer being vacuum-insulated.

The embodiments described herein are merely illustrative of the technical solutions of this application and are therefore intended to limit the scope of protection of this application.
