The pipeline may include but is not limited to a sodium hypochlorite pipeline.

[0044] Understandably, the quantum ring descaling device of a nuclear power plant can be a terahertz vibration wave descaling device, which can be made of high-silicon aluminum alloy materials doped with multiple elements to form a unique lattice structure with the characteristics of multi-level spectra in the terahertz band. It can be understood by referring to memory alloys such as neodymium iron fluoride permanent magnets. This alloy can store an almost unlimited number of spectra and emit oscillation waves into the water in a constant and stable form, which is basically unaffected by the ambient temperature. Terahertz wave radiation increases the electronic energy level of the lattice subatomic state, causing the lattice of the memory alloy material to vibrate, and the high-energy-level electrons exchange energy with the lattice simple vibration, generating quantum excitation and emitting phonons, forming terahertz wave excitation phonon wave radiation, which can penetrate metals and non-metals, but is easily absorbed by polar materials such as water and water-containing materials. After the terahertz vibration wave descaling device is excited, the material lattice will produce continuous oscillations due to the influence of the surrounding heat. The surrounding space above -60℃ has disordered thermal radiation of a certain energy level. When the disordered thermal radiation nearby exchanges energy with the electrons on the surface of the memory alloy material, the solid lattice absorbs the thermal radiation of the surrounding environment through electrons, and continuously excites phonon waves according to the spectral frequency of the lattice memory, thereby generating phonon wave radiation. This radiation is the pre-recorded active molecular oscillation, and the energy and quasi-momentum are conserved, thereby achieving continuous passive emission. The radiation energy is actually converted from the ambient thermal energy into phonon wave energy, without the need for special electrical, magnetic, or mechanical energy drive, so it becomes passive radiation. It can be understood that the internal structure of the quantum ring can be implemented using mature existing technologies.

[0045] It can be understood that two connecting parts are provided at one end of each semi-ring body, so that the two semi-ring bodies are more stable when connected together, and avoid the single connecting part causing the bolt and nut to loosen or detach due to factors such as vibration, causing the two semi-ring bodies to loosen or detach, resulting in the inability to continue the quantum descaling work.

The fluid molecules are activated to change the disordered water flow and the fluctuations caused by the micro-vibration waves, so that scale, sediments, etc. cannot adhere to the pipe wall. At the same time, as the disorder of the water flow changes to order, scale and other substances will be flushed out with the water flow.
