Alloy anti-scaling device for scaling prevention of salt-containing sewage

Abstract

The invention relates to the technical field of scale removal devices, and provides an alloy scale prevention device for scale prevention of salt-containing sewage. The device comprises a cover plate, a descaling cylinder, an overturning unit, a water inlet, a water outlet and a filter cylinder. The filter cartridge comprises the following components: Cu, Fe, Ni, Zn, Au, Se, Sb, Bi and a rare earth RE element. The aperture of meshes in the filter cartridge is 0.1 mm-50 mm, and a mounting ring is arranged at the top of the filter cartridge; a filtering space is defined between the filtering cylinder and the descaling cylinder. The scale inhibitor has the outstanding advantages of no addition of chemical reagents during scale prevention, no pollution, high efficiency, long acting distance, long validity period, no magnetism, no electricity, no (less) maintenance, wide application range, low cost and the like. The system can be widely applied to areas where scaling is caused by flowing media in petroleum, chemical engineering, coal and thermodynamic systems. The filter cartridge has two functions, namely an anti-scaling function and a function of filtering and isolating large-particle impurities; therefore, the filter cartridge is mounted at the water inlet end of the sewage pipeline and can play a role in scale prevention for a long time.

Description

technical field [0001] The invention relates to the technical field of scale removal devices, in particular to an alloy scale prevention device for salty sewage. Background technique [0002] At present, there are many prevention and control methods for sewage systems at home and abroad, mainly divided into chemical methods, physical methods and mechanical methods. The anti-scaling mechanism of the chemical method is to use some characteristics of the chemical anti-scaling agent to prevent the formation of scale; the anti-scaling mechanism of the physical method is to use the functions of certain physical instruments and equipment to inhibit the formation of scale; the process rule is to change or control certain Operating process conditions to destroy or reduce the chance of scale formation. There are many types of chemical antiscalants, and their descaling efficiency varies. Although they are widely used, their limitations are obvious. For example, for oilfield water with...
