Description

Technical Field

[0001] This utility model relates to an electromagnetic descaling device for pipes, belonging to the field of water treatment. Background Technology

[0002] In central circulating cooling water systems, carbon steel or galvanized steel pipes are mostly used for the circulation pipes. The circulating water is directly tap water, which contains chlorine. During circulation, this chlorine corrodes and oxidizes the pipes, causing them to rust. Rust flaking can then seep into the cooling tower's fins, affecting heat dissipation performance. Furthermore, calcium and magnesium ions in the circulating water, as the water evaporates and concentrates, can form scale, such as calcium carbonate and magnesium carbonate, which also impairs heat dissipation and increases energy consumption.

[0003] Existing solutions and their shortcomings:

[0004] The existing system uses two processes to solve this problem.

[0005] The first process involves a chemical dosing device that adds slow-release scale inhibitors and bactericides / algaecides.

[0006] The disadvantages of adding chemicals are twofold: firstly, the cost of use is very high; secondly, the added chemicals circulate continuously in the pipes and cooling towers, causing the concentration to increase and the circulating water to become very turbid. The pipes need to be cleaned regularly and manually drained, usually once every one to three months. This requires the discharge of a large amount of water, which is not conducive to energy conservation and emission reduction.

[0007] At the same time, adding too many chemicals can also affect the safety of circulating water.

[0008] The second process involves installing a softening filter: a branch line is branched off from the main pipeline, and a softening filter is installed. The softening resin in the filter softens and removes calcium and magnesium ions, thereby reducing scaling.

[0009] Disadvantages: First, because water evaporates every day, it needs to be replenished frequently; the softening filter has limited processing capacity; scale will still form on pipes and cooling towers, although the amount of scale will be slightly smaller. Second, the softening filtration is not continuous; the softening resin needs to be regenerated every 2-3 days. Third, there is the issue of wastewater discharge; resin softening and regeneration takes about 90 minutes, and additional regeneration agents are needed to rinse the resin, resulting in a large amount of wastewater discharge and increasing operating costs.

[0024] Figure 1 This is a schematic diagram of the electromagnetic scale removal device for pipes according to this utility model. Detailed Implementation

[0025] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0026] like Figure 1 As shown, the electromagnetic scale removal device for pipes includes: a housing 12, which houses the electromagnetic wave inner chamber and other core components. The housing 12 is typically made of metal to ensure strength.

[0027] Water inlet 1 is located on the upper part of the shell 12 and is connected to the incoming water pipe of the cooling water circulation system, so that the incoming water is introduced into the interior of the electromagnetic scale removal device for treatment.

[0028] The outlet 10 is located at the lower part of the shell 12 and is connected to the water outlet pipe of the cooling water circulation system, so that water enters the pipe behind it.

[0029] Water pressure gauge 2 is installed at water inlet 1 to monitor the incoming water pressure in real time.

[0030] Water pressure gauge 9 is installed at the water outlet 10 to monitor the water pressure in real time.

[0031] The magnetic wave generating control cabinet 7 is electrically connected to the electromagnetic wave inner chamber 6, generating electromagnetic waves to prevent scale formation. Furthermore, the magnetic wave generating control cabinet 7 is electrically connected to the inlet pressure gauge 2 and the outlet pressure gauge 9, receiving water pressure data from both gauges and calculating the difference. When the difference exceeds a predetermined value, it indicates that the electromagnetic scale removal device in the pipeline is clogged, prompting for cleaning.

[0032] The upper cover 3 is rotatably and sealingly connected to the upper opening of the housing 12. The upper cover 3 has a sealing strip on its edge, and after covering the opening of the housing 12 and being fastened with a snap fastener, it can prevent water leakage.

[0033] The latch 4 reversibly engages the upper cover 3 with the upper opening of the housing 12. When it is necessary to clean the inside of the device, the upper cover 3 can be opened by opening the latch 4.

[0034] In some embodiments, an electromagnetic wave inner cavity 6 is placed inside the housing 12, within the inner cavity of the housing 12.

[0035] In other embodiments, the number of electromagnetic wave inner chambers 6 is two or more, arranged side by side within the housing 12, to further improve descaling efficiency. Figure 1 The image shows a configuration with two electromagnetic wave inner chambers 6. Furthermore, two or more electromagnetic wave inner chambers 6 can be stacked vertically within the housing 12. When stacked, the frames of the two electromagnetic wave inner chambers 6 are connected by bolts or similar structures to facilitate removal and replacement of the inner chambers during cleaning.

[0036] The magnetic wave generating control cabinet 7 is electrically connected to the electromagnetic wave inner cavity 6.

[0037] The magnetic composite corrugated technology used in the electromagnetic wave inner chamber 6 is a non-chemical treatment method. Its main function is to reduce or prevent the formation of scale by calcium and magnesium ions in the water. The principle and mechanism of action are as follows:

[0038] The inner chamber 6 of the electromagnetic wave emits electromagnetic waves of a specific frequency, breaking the bonds between ions and causing them to recombine into non-depositing substances, thus preventing them from adhering to the inner wall of the pipe and forming scale.

[0039] The modulation signal generator in the magnetic wave control cabinet 7 generates a complex frequency modulation signal, which is transmitted to the inside of the pipe through a signal cable, forming a molecular force dynamic interference field, or ADDMF signal field. This interference field can change the physical structure of fluid and dissolved salt molecules, generating an electromagnetic field of specific frequency and intensity to affect the water flow through the equipment. When water containing calcium and magnesium ions passes through the electromagnetic field, the original associated chain-like macromolecules break into individual water molecules. The positive and negative ions of dissolved salts in the water are surrounded by individual water molecules, reducing their movement speed, the number of effective collisions, and the electrostatic attraction. This prevents calcium and magnesium ions in the water from combining with carbonate ions to form calcium carbonate and magnesium carbonate, thus achieving an anti-scaling effect. When calcium and magnesium ions in the water combine with carbonate ions, they would originally form hard and dense calcite crystals, which easily adhere to the pipe wall. The electromagnetic field changes the distribution of the ion electron cloud through induced polarization, causing the crystal growth direction to shift and transforming it into loose aragonite crystals. Aragonite crystals have weak surface charge and low adhesion, so they are suspended in water and can be adsorbed into filter screens or filter media. Once they accumulate to a certain extent, the filter screen can be cleaned or the filter media can be replaced.

[0040] At the same time, as the water absorbs a large number of excited electrons, the dipole moment of the water increases, and the affinity of the positive and negative ions of salt increases, which makes the original scale on the pipe wall gradually soften and fall off, achieving an effective descaling effect.

[0041] Electromagnetic fields of specific frequencies and intensities can also inhibit the growth of microorganisms in water. The electromagnetic waves generate turbulence in the water, disrupting ion channels in cell membranes. This alters the cells' internal control currents and the environmental conditions necessary for survival, causing them to lose their ability to live and die. Simultaneously, the stimulated water molecules can surround and block dissolved oxygen in the water, cutting off the oxygen source needed for microbial life processes, thus achieving a good bactericidal and algae-killing effect and preventing the formation of biological sludge.

[0042] The electromagnetic wave inner chamber 6 has an external filter frame to intercept or filter larger scale particles in the incoming water.

[0043] The inner hook 5 of the filter screen is located on the upper part of the filter frame and is hooked to the hanging point inside the housing 12. The hanging point can be a protrusion on the inner cavity of the housing, or a horizontal bar or reinforcing rib on the filter screen, etc., that can provide a hanging position.

[0044] The filter frame contains multiple layers of filter screens, each with a different pore size. This allows for the filtration of dirt and debris of varying sizes. During cleaning, only the filter layers that trap more dirt can be replaced, shortening cleaning time and reducing downtime for the cooling water circulation system.

[0045] In some embodiments, the filter layer located on the inner cavity 6 of the electromagnetic wave chamber has an upward-facing sealing edge that fits into the inner cavity of the housing 12, thereby enhancing the filtration effect on large dirt particles in the incoming water.

[0046] Removable filters are installed at the water inlet and outlet to filter out large pieces of dirt and debris from the incoming water.

[0047] Cleaning is quick; simply open and remove the generator to clean it.

[0048] It also features a flow meter, located at the water outlet 10. The magnetic wave generating control cabinet 7 is electrically connected to the flow meter to monitor the circulating water flow rate in real time. When the flow rate is too low, it issues a warning signal to ensure the effectiveness of the electromagnetic scale removal device in the pipeline.

[0049] In some embodiments, the housing 12 also contains a water hardness sensor, which is electrically connected to the magnetic wave generating control cabinet 7 to detect the concentration of calcium and magnesium ions in the water in real time, investigate the causes of water quality changes, and indicate the intensity required for scale cleaning or to improve the quality of incoming water in advance.

[0050] The circuit, chip, connects to two pressure sensors, calculates the difference, and when it exceeds a predetermined value, an alarm is displayed on the controller's screen, prompting the descaling unit to be cleaned.

[0051] The magnetic wave generating control cabinet 7 contains a microcontroller and corresponding differential amplifiers and signal generators, as well as other electrical chips in the field, all of which use mature commercial chips and circuits in the field.

[0052] When it is necessary to clean the electromagnetic scale removal device for pipes, simply open the latch 4, open the upper cover 3, lift the inner hook 5 of the screen, take out the electromagnetic wave inner chamber 6, clean the dirt inside, put it back in, and close the latch 4.

[0053] The electromagnetic scale removal device for pipes described in this embodiment achieves a significant reduction in the pipe structure of the cooling water circulation system without the need for additional chemicals or softening resin. Furthermore, the cleaning process is simple and quick, minimizing downtime of the cooling water circulation system. It also provides both descaling and sterilization effects.
