The high-pressure water cleaning method is mainly used as a physical method for removing dirt on the surface of materials in industrial production. The high-energy water jet jetted out at a very high speed through a high-pressure nozzle hits the scale layer violently to achieve the purpose of descaling. High-pressure water cleaning has the advantages of short construction time, labor-saving, safe operation, and no damage to equipment. However, special equipment for high-pressure water cleaning is usually expensive and not universal.
Ultrasonic
When the ultrasonic waves propagate in the medium solution, the distance between the liquid molecules is changed,the molecular cohesion is greatly reduced, the surface tension and viscosity of the solution are significantly reduced, the crystallization induction period of the scaling salts is shortened, and the nucleation rate is increased. Promote scale salts to combine directly in the solution body to form crystals. At the same time, the cavitation effect of ultrasonic waves on the solution medium creates cavities in the liquid, and the strong pressure peak generated when it breaks can crush the precipitated scaling salt crystals into fine particles suspended in the medium, and then flow away with the liquid . The method has continuous equipment, high automation level, no chemical pollution, no need for special operation, greatly shortens the washing time, reduces labor intensity of workers, and has important significance in environmental protection, energy saving, improvement of work efficiency and other aspects. However, an additional ultrasonic device needs to be added,which consumes electric energy and causes ultrasonic pollution; in addition, the removal effect on oily dirt is not obvious.
Chemicals
Pickling is the most common descaling method in the industry. Dilute hydrochloric acid is mostly used to act on the hardened scale to generate soluble calcium chloride, which is discharged together with the waste liquid. The effect is remarkable, and it can act on most insoluble metal carbonates or basic carbonates. The disadvantage is the corrosiveness of the acid, which is not only corrosive to the equipment, but also cannot be used in situations where there are more precise flow control valves installed in the pipeline; it also poses a threat to the safety of the operators, and it also needs to be shut down during operation. Moreover, the waste liquid after pickling must be adjusted to neutrality before it can be transported to the wastewater treatment station for treatment, and direct discharge will cause environmental hazards.
Scale inhibitors are different from pickling. Complexing agents are added to the working fluid in a regular, quantitative, and slow-release manner. Scale inhibitors (usually phosphate or metacarboxylate) or calcium ions and complexes The mixture reacts to generate soluble complex ions, or makes the working medium weakly acidic, so that calcium carbonate cannot be formed, so as to achieve the purpose of scale inhibition. By adding antiscalants reasonably, a very good antiscaling effect can be achieved, and there is no need for descaling operations for a long time, which saves a lot of operating costs. The disadvantage is that the chemical composition of the fluid system is changed, the risk of environmental pollution is greater, and it is still corrosive to the equipment.
