The number of chips 8 can be any combination of numbers between 2 and 15. The thickness of the chip 8 is 5 - 20 mm. The distance between adjacent chips 8 is 45 - 90 mm. The hole pattern of the chip 8 is a combined structure composed of a cross hole pattern 15, a semi-cross hole pattern 13, and a linear hole pattern 14, that is, a number of holes of the cross hole pattern 15, the semi-cross hole pattern 13, and the linear hole pattern 14 are distributed on the same chip 8 at the same time. See the attachment for details. Figure 3 , the layout of multiple hole patterns can be arranged regularly from the inside to the outside according to Figure 3 , or can be designed and arranged according to actual requirements. This combined hole pattern can increase the reaction contact area between the fluid and the chip 8, improve the descaling efficiency, and the resistance loss of the fluid passing through the chip 8 is smaller. The widths of the cross hole pattern 15, the semi-cross hole pattern 13, and the linear hole pattern 14 are any data between 2 and 12 mm. Figure 3Among them, the installation hole opened at the center of the chip 8 is for the long stud 9 to pass through. Multiple semi-cross hole types 13 are arranged circumferentially in the first inner ring, and multiple cross hole types 15 and multiple linear hole types 14 are arranged circumferentially in the second outer ring. The multiple linear hole types 14 are evenly interspersed between the multiple cross hole types 15. The material of the chip 8 is a special alloy material (using the alloy material in Chinese Patent CN111519065B, and this alloy material contains the following components in mass percentage: Cu: 45% - 55%, Zn: 22% - 35%, Ni: 11% - 25%, Sn: 2% - 4%, Al: 2% - 3.5%, Mn: 1.5% - 3.5%, Au: 0.01% - 0.1%). This material has excellent anti-scaling and anti-corrosion functions. By using the potential difference generated between alloy elements, countless tiny battery reactions are formed, precipitating a certain amount of divalent cations, increasing the solubility of scale and hindering the dissolution and precipitation of scale. Specifically, by using the potential difference between alloy elements, when the fluid medium contacts this alloy material, an electrode system of the multi-element alloy and the electrolyte solution is formed. The metal with a lower electrode potential in the alloy is first oxidized into ions and enters the solution. At the same time, electrons are released into the solution and form a stable material structure with Ca2+ and Mg2+, no longer forming scale (the principle that no scale is formed when the fluid medium contacts this alloy material is the prior art). The entire device of the present utility model has the functions of anti-scaling, anti-corrosion, anti-waxing and anti-saponification.

[0040] The operating principle of the device of the present utility model is as follows:

[0041] The device of the present utility model relies on the reducing joint 5 and the straight-through joint 2. Quick plugging and unplugging can be achieved between the two joints, and the installation process is simpler. Only the interface position needs to be inserted. The fluid flows into the device of the present utility model through the external device 1 and contacts the chip 8. The chip 8 is composed of a special alloy material. The surface of the chip 8 is provided with a combined hole type structure of cross hole types 15, semi-cross hole types 13 and linear hole types 14. This combined hole type structure increases the contact area between the fluid and the alloy material. During the process of the fluid passing through the combined hole type structure of the chip 8, by using the potential difference generated between alloy elements, countless tiny battery reactions are formed, precipitating a certain amount of divalent cations, increasing the solubility of scale and hindering the dissolution and precipitation of scale. Thus, the effect of preventing scale formation is achieved. The device of the present utility model is non-magnetic, non-electric, simple to maintain, convenient to install, environmentally friendly, and will not cause secondary environmental pollution, and has great application value.
