Boiler water treatment agent

Abstract

The invention relates to a boiler water treatment agent which comprises the following components in percentage by weight: 15-40 wt% of copolymer of hydroxyl propyl acrylate, 15-40 wt% of sulfonated styrene, 10-24 wt% of copolymer of hydroxyethyl methacrylate, 10-18 wt% of sodium sulfite, 10-15 wt% of phosphino carboxylic acid, 10-15 wt% of trisodium phosphate and 3-6 wt% of sodium hydroxide. By using the boiler water treatment agent provided by the invention, the hardness of boiler water can be lowered, and the formation of water scale is reduced and inhibited. After the boiler water treatment agent is used, the oxygen content of boiler water is within the national standard range. The boiler water treatment agent provided by the invention also has the actions of residue and hard scale elimination and scale prevention.

Description

Technical field [0001] The present invention is a water quality purification technology field, and especially involves a water treatment agent for boiler stuffing and scale anti -anti -treatment. Background technique [0002] Boiler equipment is an indispensable energy supply equipment for industrial development. It has the characteristics of large volume, difficulty in installing and replacement. Therefore, regular maintenance and cleaning need to delay its aging speed as much as possible. [0003] Corrosion and scale attachment to shorten the life of the boiler device and reduce the heat conduction of the boiler is the cause of hindering the stable operation.Therefore, in the boiler device, it is usually used to suppress the above -mentioned corrosion and scale attachment.Using only soft water for deoxidation as water, it is difficult to effectively inhibit corrosion and stains.In the current technologies, chemical treatment and physical treatment are often used to remove disso...

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
