Multifunctional water treatment agent

Abstract

The invention relates to a multifunctional water treatment agent which comprises the following components by weight: 15-30 wt% of polyepoxysuccinic acid, 15-30 wt% of polyacrylic acid, 6-18 wt% of acrylic acid / sulfo allylamine / maleic acid, 10-15 wt% of potassium sulfite, 2-8 wt% of ethylene diamine tetraacetic acid, 10-15 wt% of trisodium phosphate, 15-25 wt% of sodium carbonate, and 3-7 wt% of sodium hydroxide. The boiler water treatment agent of the invention can decrease boiler water hardness, reduce and prevent the formation of scale; with the water treatment agent, the oxygen content of boiler water is within national standard ranges; the boiler water treatment agent of the invention also has the functions of residual hardness removal and scale prevention.

Description

technical field [0001] The invention belongs to the technical field of water quality purification, and in particular relates to a water treatment agent used for scale inhibition and scale prevention of boilers. Background technique [0002] Boiler equipment is an indispensable energy supply equipment for industrial development. It has the characteristics of large size and difficult installation and replacement. Therefore, it needs regular maintenance and cleaning to delay its aging speed as much as possible. [0003] In the current technology, chemical treatment and physical treatment are often used to remove dissolved oxygen. In chemical treatment, oxygen scavengers such as iodine, light amine groups or sugars have been widely used. When chemically treated with light amine groups, light amines generate acids such as nitric acid, which increases corrosion to boilers. The disadvantage of sugar is that it is difficult to measure its residue concentration in boiler water, so ...

AI Technical Summary

Problems solved by technology

When chemically treated with light amine groups, light amines generate acids such as nitric acid, which increases corrosion to boilers

The disadvantage of sugar is that it is difficult to measure its residue concentration in boiler water, so it is difficult to control the correct addition amount, and sugar will produce odor when it encounters steam

Soda ash method, sodium ion exchange method, electronic anti-scaling instrument and other methods are usually used for boiler descaling and anti-scaling, but the descaling effect of the above methods is not ideal

[0004] At the same time, the scale inhibitors provided by the prior art have achieved different effects in different applications, but there is no satisfactory scale inhibitor product for high calcium, high sulfate, and high soluble silicon water quality.
