Description

TECHNICAL FIELD

[0001] The utility model relates to scale removing technical field, concretely relates to electromagnetic scale removing device of high hardness industrial circulating water. BACKGROUND

[0002] In industrial production, circulating water systems are widely used. However, when the hardness of circulating water is high, calcium, magnesium and other ions in the water are easy to form scale on the surface of the pipeline and equipment. The presence of scale can reduce heat exchange efficiency, increase energy consumption, and may also cause problems such as pipeline blockage, equipment corrosion, shorten the service life of equipment, and increase maintenance costs and downtime.

[0003] The existing scale removal methods include chemical scale removal, mechanical scale removal, etc. Chemical scale removal produces chemical wastewater, pollutes the environment, and may corrode equipment over a long period of use; mechanical scale removal requires shutdown operation, affecting production continuity, and the scale removal effect inside some complex pipelines and equipment is not good.

[0004] As a physical scale removal method, electromagnetic scale removal technology has the advantages of environmental protection and no need to stop production, but the existing electromagnetic scale removal devices are not ideal for scale removal of high hardness industrial circulating water. Since most of these electromagnetic scale removal devices directly wrap coils around pipelines with regular surfaces, the magnetic field generated by the coils cannot effectively act on the circulating water in the center of the pipeline, resulting in insufficient magnetic field strength and uneven magnetic field distribution. In addition, since the circulating water flows uniformly along the pipeline, the ion distribution in the circulating water is uneven, affecting the scale removal effect. SUMMARY

[0012] Preferably, the coil is wound in the annular groove, the permanent magnet ring is a detachable structure, is fixedly arranged in the annular groove, and only one coil or permanent magnet ring is arranged in each annular groove.

[0014] Preferably, the pipeline is fixedly connected with flanges at both ends.

[0015] Preferably, the pipeline is fixedly connected with a fan for heat dissipation of the pipeline and the coil.

[0016] Preferably, the air output direction of the fan corresponds to all the annular grooves.

[0017] Preferably, the pipeline is fixedly connected with a flow guide assembly for guiding the circulating water to be uniformly dispersed into the annular cavity in the pipeline.

[0022] 1. By setting several annular grooves on the pipeline, the inside of the pipeline can form regions with continuously alternating sizes of inner diameter, when the circulating water flows in the pipeline, turbulence can be generated, at the same time, the coil is installed in the annular groove, which can increase the area of the circulating water corresponding to the coil, reduce the distance between the coil and the circulating water in the center part of the pipeline, and improve the electromagnetic range and descaling effect without increasing the number of coils, the ions in the water can be more uniformly distributed in the water flow through the turbulent circulating water, avoiding the formation of scale caused by the local high concentration of ions, further improving the electromagnetic descaling effect;

[0023] 2. By setting a permanent magnet ring for assisting the coil, the magnetic field strength can be improved, the presence of the permanent magnet ring makes the magnetic field maintain a certain stability at different frequencies and strengths, further improving the descaling effect;

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope protected by the utility model.

[0033] Referring to Figures 1-4 The utility model provides electromagnetic descaling device of high hardness industrial circulating water, including pipeline 1, the surface of pipeline 1 is equidistant along the axial direction of pipeline 1 and is provided with a plurality of annular grooves 2;

[0034] Pipeline 1 is fixedly connected with electromagnetic generating assembly 4, electromagnetic generating assembly 4 has a plurality of coils 8, and the surface of pipeline 1 is fixedly connected with a plurality of permanent magnet rings 3, and a plurality of coils 8 and a plurality of permanent magnet rings 3 are alternately arranged in a plurality of annular grooves 2.

[0035] Electromagnetic generating assembly 4 is prior art, adopts general type, is mainly composed of power supply, controller, coil 8, and its working principle is that power supply provides electric energy, and controller controls the frequency, intensity and other parameters of electric current, so that coil 8 generates specific alternating magnetic field.

[0036] As optional implementation, coil 8 is wound in annular groove 2, permanent magnet ring 3 is detachable structure, is fixedly installed in annular groove 2, and only one coil 8 or permanent magnet ring 3 is arranged in each annular groove 2.

[0037] The purpose of setting permanent magnet ring 3 is that the constant magnetic field generated by permanent magnet ring 3 and the alternating magnetic field generated by coil 8 are superimposed on each other, the comprehensive effect of the magnetic field is enhanced, the existence of permanent magnet ring 3 makes the magnetic field maintain a certain stability under different frequencies and intensities, and the descaling effect is further improved.

[0038] Permanent magnet ring 3 includes two arc magnets 12, and the two ends of the arc magnets 12 are fixedly connected with connecting plates 13. Correspondingly, the two connecting plates 13 are fixedly connected by nuts 14 and bolts 15. This design facilitates the installation of the permanent magnet ring 3.

[0039] The flanges 5 are fixedly connected to the two ends of the pipeline 1.

[0040] The fan 6 is fixedly connected to the pipeline 1, which is used for heat dissipation of the pipeline 1 and the coil 8. Since the circulating water has heat, the pipeline 1 is cooled by the fan 6, so that the circulating water can be cooled when passing through the pipeline 1. At the same time, the coil 8 also generates heat when working, and the fan 6 can cool the coil 8.

[0041] The air flow output direction of the fan 6 corresponds to all the annular grooves 2, and the annular grooves 2 increase the surface area without changing the length of the pipeline 1, thereby improving the heat dissipation efficiency of the circulating water.

[0042] The pipeline 1 is fixedly connected with a flow guide assembly 7 for guiding the circulating water, so that the circulating water is uniformly dispersed into the annular cavities in the pipeline 1. By arranging a plurality of annular grooves 2 on the pipeline 1, regions with continuously alternating sizes of inner diameters can be formed in the pipeline 1, and the part with a larger inner diameter is the annular cavity.

[0043] The flow guide assembly 7 can further improve the turbulence degree of the circulating water flowing in the pipeline 1.

[0044] The flow guide assembly 7 includes a mounting rod 9 fixedly connected in the pipeline 1, and a plurality of conical caps 11 fixedly connected on the mounting rod 9.

[0047] The circulating water is guided by the conical cap 11, so that the flow direction of the circulating water corresponds to the annular cavities in the pipeline 1, and the annular cavities can cause the circulating water originally flowing along the length direction of the pipeline 1 to be turbulent.

[0048] By arranging a plurality of annular grooves 2 on the pipeline 1, regions with continuously alternating sizes of inner diameters can be formed in the pipeline 1. When the circulating water flows in the pipeline 1, the inner wall of the pipeline 1 is not smooth, so that the circulating water can collide with the inner wall of the pipeline 1, thereby causing the circulating water to be turbulent.

[0049] The coil 8 is arranged in the annular groove 2, which can increase the area corresponding to the coil 8 and the circulating water, thereby improving the electromagnetic range without increasing the number of coils 8. The turbulent circulating water can make the ions in the water more uniformly distributed in the water flow, avoiding the formation of scale caused by the local high ion concentration, and also helping to improve the efficiency of the magnetic field on the ions.

[0050] The permanent magnet ring 3 is arranged to assist the coil 8, which can improve the magnetic field strength.

[0051] The above merely describes a specific implementation of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
