Description

Technical Field

[0001] This utility model relates to the field of pipeline maintenance technology, specifically to an alloy physical scale inhibitor device. Background Technology

[0002] Scale buildup is a common technical problem in industrial production and pipeline transportation. Scale formation leads to a reduction in pipeline cross-sectional area, decreased heat transfer efficiency, and increased energy consumption. In severe cases, it can also cause safety hazards such as pipeline blockage and corrosion perforation, affecting production continuity and increasing maintenance costs.

[0003] Currently, scale inhibition technologies are mainly divided into two categories: chemical methods and physical methods. Chemical methods achieve their effect by adding scale inhibitors, but they suffer from drawbacks such as environmental pollution, equipment corrosion, the need for regular replenishment, and high costs, which do not align with the trend of green and environmentally friendly industrial development. Physical methods include electromagnetic treatment, ultrasonic treatment, and turbulent flow disturbance. Among these, electromagnetic physical scale inhibition equipment is widely used due to its advantages of no secondary pollution and low operating costs, but existing equipment still has many shortcomings.

[0004] On the one hand, the core components of existing physical scale inhibition equipment are mostly made of ordinary stainless steel or carbon steel, which are prone to corrosion and wear in high-hardness and high-corrosive water environments, resulting in a shortened service life of the equipment, and require a continuous supply of energy to maintain the existence of the electromagnetic field. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an alloy physical scale inhibition device, which aims to solve the above-mentioned technical problems.

[0006] An alloy physical scale inhibition device includes a rotating shaft, a fixed frame, a cylinder, and a pipe. The cylinder is provided with a disassembly assembly, and the cylinder and the pipe are detachably connected through the disassembly assembly. The fixed frame is fixedly connected to the cylinder, and the rotating shaft is rotatably connected to the fixed frame. A turbulence arm is provided on the rotating shaft.

[0007] The fixed frame, rotating shaft, and turbulence arm are all made of titanium alloy.

[0008] The turbulent arm is equipped with a permanent magnet, and an induction coil is wound around the outside of the cylinder. The two ends of the induction coil are electrically connected to a first electrode and a second electrode, respectively. The first electrode and the second electrode are coaxial rings, and their axis passes through the water flow in the cylinder.

[0009] The first and second electrodes are made of Hastelloy.

[0010] Optionally, the turbulent arm is a circular tube, with both its beginning and end fixedly connected to the rotating shaft, and the beginning and end of the turbulent arm are staggered in the axial direction of the rotating shaft.

[0011] Optionally, the turbulence arms are provided in multiple sets and are evenly distributed around the circumference of the rotation axis.

[0012] Optionally, the turbulence arm is an arc-shaped arm.

[0013] Optionally, the disassembly assembly includes a threaded ring and a nut. The threaded ring is coaxially and fixedly connected to the cylinder. Multiple threaded rings are evenly arranged along the circumference of the cylinder. The nut engages with the threaded portion of the threaded ring.

[0014] Optionally, the cylinder body is also provided with a positioning groove corresponding to the pipe.

[0015] This utility model has the following beneficial effects:

[0016] (1) This device does not require an external power supply and its operation depends entirely on the kinetic energy of the water flow in the pipeline. The device converts the kinetic energy of the water flow into the energy required for scale inhibition through the built-in rotor, which solves the problem of continuous power consumption of traditional electromagnetic scale inhibition equipment, improves the applicability of the device, and increases the energy-saving effect of the device.

[0017] (2) This device generates a time-varying magnetic field by rotating a permanent magnet and synchronously generates an alternating electric field based on the principle of electromagnetic induction. The synergistic effect of the rotating magnetic field and the alternating electric field can simultaneously interfere with the dynamic process and crystallization behavior of scale-forming ions from different physical perspectives, resulting in a more comprehensive and stable scale inhibition performance.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 Figures 1-5 As shown, this utility model is an alloy physical scale inhibition device, including a rotating shaft 1, a fixed frame 3, a cylinder 4, and a pipe 5. The cylinder 4, as the core carrier of the water flow channel, is detachably connected to the pipe 5 through a disassembly assembly, facilitating subsequent equipment maintenance, component replacement, and pipe cleaning. The fixed frame 3 adopts a structure adapted to the cylinder 4 and is assembled and fixed to the cylinder 4 through a fixed connection method. After assembly, the position of the fixed frame 3 relative to the cylinder 4 is stable, providing reliable installation support for the rotating shaft 1. The rotating shaft 1 and the fixed frame 3 adopt a rotatable connection structure, ensuring that the rotating shaft 1 can rotate flexibly relative to the fixed frame 3. A turbulence arm 2 is mounted on the rotating shaft 1. The rotation of the rotating shaft 1 drives the turbulence arm 2 to move synchronously, realizing the disturbance effect on the water flow inside the cylinder, and under the action of the water flow, the turbulence arm 2 rotates circumferentially along the axis of the rotating shaft 1.

[0029] In terms of material selection, the fixed frame 3, rotating shaft 1, and turbulent arm 2 are all made of titanium alloy. Titanium alloy has high strength, corrosion resistance, wear resistance, and good magnetic permeability adaptability, which can adapt to the complex working conditions of industrial water bodies, extend the service life of the equipment, and at the same time avoid the pollution of water bodies caused by the corrosion of the material itself, ensuring the cleanliness of the physical scale inhibition process. An adaptation installation space is reserved inside the turbulent arm 2 to securely install the permanent magnet 6. The arrangement direction of the permanent magnet 6 forms an adaptation angle with the water flow direction, ensuring that the magnetic field it generates can fully act on the water flowing through the cylinder 4. The induction coil 7 is coiled in a circular layout on the outside of the cylinder 4. The coiling density of the induction coil 7 is uniform, ensuring a balanced magnetic field distribution. The two ends of the induction coil 7 are electrically connected to the first electrode 8 and the second electrode 9, respectively, ensuring smooth circuit conduction. Both the first electrode 8 and the second electrode 9 are designed as coaxial ring structures. During installation, it is strictly ensured that their axes coincide with the water flow path in the cylinder 4, so that the electric field generated by the electrodes can fully cover the water flow channel. The first electrode 8 and the second electrode 9 are made of Hastelloy, which has excellent corrosion resistance, conductivity and high temperature stability. It can adapt to the working environment of humid and high temperature water flow such as cooling towers, while ensuring the long-term stable operation of the electrodes and avoiding electrode wear from affecting the electric field strength.

[0030] In one embodiment, the permanent magnet 6 is a neodymium iron boron strong magnet. This method is suitable for situations where the fluid flow rate in the pipe 5 is low. It can increase the magnetic field strength and magnetic flux formed by the permanent magnet 6. The disadvantage is that the cost is high and the strong magnetic field will affect the external metal.

[0031] Figure 3 This is one embodiment of the turbulent flow arm 2, which is suitable for situations where the fluid velocity in the pipe 5 is high. When the velocity is low, the diameter of the turbulent flow arm 2 can be appropriately increased or blades can be added to increase the force-bearing area of ​​the turbulent flow arm 2 on the water flow and increase the rotational speed of the turbulent flow arm 2.

[0032] The following details the synergistic scale inhibition principle of magnetic and electric fields. Scale is mainly composed of calcium and magnesium. Magnetic and electric fields can inhibit scale formation by physically disturbing ions and altering their crystallization behavior. Magnetic field scale inhibition relies on the Lorentz force. When water flows through the rotating alternating magnetic field formed by the permanent magnet, the charged calcium and magnesium cations and bicarbonate anions in the water are continuously acted upon by the Lorentz force, causing disordered deflection and spiral motion. This disrupts the process of ion directional aggregation and the formation of stable crystal nuclei, while simultaneously interfering with the crystallization path of carbonates, causing them to transform into loosely structured, non-adhesive aragonite and spherulite crystals that are difficult to adhere to the pipe wall, allowing the scale to flow through the water in a flocculent form. Electric field scale inhibition relies on the alternating electric field force. The first electrode 8 and the second electrode 9 are powered by the induction coil 7. An equivalent capacitor is formed between them, and an alternating electric field that penetrates the water is generated in the pipe 5 through the capacitive coupling effect. On the one hand, it drives the ions in the water to make periodic radial reciprocating oscillations, further destroying the growth and aggregation of crystal nuclei. On the other hand, it polarizes water molecules, weakens the electrostatic adsorption force between microcrystals and pipe walls, and reduces the possibility of scale adhesion. In this device, the rotating magnetic field and the coupled electric field are both driven by the same set of permanent magnets 6. The two are of the same origin, frequency and phase synchronization, forming a magnetoelectric synergistic scale inhibition effect. The spatial three-dimensional disturbance brought by the Lorentz force and the directional reciprocating drive brought by the electric field force are superimposed to interfere with the migration, collision and crystallization of calcium and magnesium ions, inhibit the formation of dense hard scale, reduce the adhesion of microcrystals to the pipe wall, and finally achieve the effect of delaying scale formation and reducing scale accumulation in pipe 5.

[0033] Optionally, the turbulence arm 2 is designed as a circular tube structure, with both its beginning and end securely assembled to the rotating shaft 1 via a fixed connection. In the axial direction of the rotating shaft 1, the beginning and end of the turbulence arm 2 are staggered. This structural design allows the turbulence arm 2 to create multi-directional, asymmetrical disturbances to the water flow as it rotates with the rotating shaft 1, breaking the laminar flow state, increasing the contact area and duration of the water flow with the magnetic and electric fields, and improving the scale inhibition effect.

[0034] Optionally, to further optimize the water flow disturbance effect, multiple sets of turbulence arms 2 are provided, with each set of turbulence arms 2 evenly distributed circumferentially along the axis of rotation 1. The evenly distributed structure ensures that the water flow is subjected to balanced disturbance in all areas of the cylinder 4, avoiding dead zones in the water flow, making it difficult for scale particles in the water to adhere and deposit, while ensuring the uniformity of the magnetic and electric fields in the water flow channel, thus improving the overall scale inhibition effect.

[0035] Optionally, the turbulent arm 2 is an arc-shaped arm. During rotation, the arc-shaped turbulent arm 2 can further disturb the water flow, further disrupt the conditions for scale crystal formation, and at the same time promote the discharge of already formed tiny scale particles with the water flow, thereby strengthening the synergistic effect of scale inhibition. Furthermore, increasing the rotation speed of the water-driven turbulent arm 2 improves the electro-induced scale inhibition effect.

[0036] Optionally, the disassembly assembly specifically includes threaded rings 10 and nuts 11. Multiple threaded rings 10 are evenly distributed circumferentially along the cylinder 4, and the thread specifications of the multiple threaded rings 10 are consistent. The thread structure of the nut 11 is adapted to the threaded portion of the threaded rings 10. During installation, after aligning the connection end of the pipe 5 with the cylinder 4, the nut 11 is locked and fixed by the threaded engagement of each threaded ring 10. Figure 5 The top of the threaded ring 10 shown is provided with a tapered ramp, which facilitates the threaded engagement of the nut 11 and the threaded ring 10 to complete the quick assembly of the cylinder 4 and the pipe 5. When disassembling, simply loosen the nut 11 to separate the cylinder 4 and the pipe 5. The operation is convenient and efficient, and it is convenient for the daily maintenance and repair of the equipment.

[0037] Optionally, to improve the accuracy and stability of the connection between the cylinder 4 and the pipe 5, the cylinder 4 is also provided with a positioning groove 12 corresponding to the pipe 5. The shape and size of the positioning groove 12 are adapted to the connection end of the pipe 5. During installation, the connection end of the pipe 5 can be embedded in the positioning groove 12 to achieve quick positioning, ensure the coaxiality of the cylinder 4 and the pipe 5, avoid connection deviation that may cause poor water flow or leakage, and enhance the structural stability after the connection, ensuring the reliability of the equipment during operation.

[0038] When this equipment is working, the rotating shaft 1 drives the turbulent arm 2 to rotate. The multiple sets of turbulent arms 2 with a torsional design and uniform distribution create an all-round, spiral disturbance to the water flow. The permanent magnet 6 inside the turbulent arm 2 generates a stable magnetic field. At the same time, the first electrode 8 and the second electrode 9 generate an electric field covering the water flow channel after being energized. The magnetic field and the electric field work together to destroy the formation and adhesion conditions of scale crystals, thus achieving physical scale inhibition. The detachable connection structure and positioning groove 12 ensure the convenience and stability of equipment installation and maintenance, and the overall equipment meets the requirements of high efficiency and long-term scale inhibition in industrial scenarios.
