Antiscaling compound and method for preventing and removing scale

Abstract

The invention relates to an antiscaling compound and a method for preventing and removing scales; the ingredients of the antiscaling compound comprises: 20-50 percent of natural zeolite, 25-20 percent of TiO, 10-40 percent of V2O5, 20-40 percent of SiO2, and 5-20 percent of NdFeB; the antiscaling compound is an ensemble of regular or irregular solid fine particles or an ensemble of solid porous particles; the average diameter of the fine particles of the antiscaling compound is 0.5-15mm; when the average diameter of the particles of the antiscaling compound is more than 15mm, porous particles are adopted, the pore diameter of the particle is more than 20mum and penetrates through the particle; the density of the antiscaling compound is 1.2-5g / cm<3>; the method for preventing and removing scales is that: the antiscaling compound is placed in water of a heating jacket of a water system freely for preventing and removing the scales in the water system, a filter screen is arranged at the outlet of the water jacket to prevent the antiscaling compound particles from being drained; or the antiscaling compound is placed in a volume body with meshes to form a water processor, the processor is placed nearby the heater and is arranged at the water charging port of the water system to processing charged water. The invention can process the scales efficiently for a long time without secondary pollution, the water treatment is safe, real-time on-line scale removal can be carried out, and the installation and usage are convenient and rapid.

Description

technical field [0001] The invention relates to the technical field of a physical anti-scaling substance and its anti-scaling and descaling method, which is used for preventing or removing scales on the surfaces of heaters and anti-scaling substances in contact with water. [0002] The utility model relates to a device mainly composed of an anti-scaling material or an anti-scaling material, which can prevent or remove scales on the surface of a heater in contact with water and the surface of the anti-scaling material at low cost, conveniently and automatically. Background technique [0003] In the process of heating water by the heater, the scale formed on the heating surface has an adverse effect on the heat transfer efficiency, service life and safety performance of the heater. It is a hygienic and safe method to prevent the formation of scale and remove the formed scale. One of the key technical issues of energy conservation and environmental protection. [0004] Some me...

Problems solved by technology

These patents are practical, but have their own shortcomings. The descaling mechanism of Chinese patent 200420047737.0 is the contact effect of the sphere flowing with hot water, so it is emphasized that the sphere with a specific gravity close to 1 (slightly larger or slightly smaller) that is most conducive to moving with hot water is emphasized. , while ignoring the more important descaling effect of heterogeneous nucleation on the surface of the sphere, so no attempt has been made to fully utilize the surface of the sphere, which limits the descaling efficiency; Automatically cleans the scale problem, it is very inconvenient to use for a long time
