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

Embodiment 1

[0031] According to the weight fraction calculation, it is made up of the following components: buy commercially available potassium sulfite 10wt%, polyepoxysuccinic acid 18wt%, polyacrylic acid 22wt%, the copolymer of acrylic acid / sulfoacrylamine / maleic acid 12wt%, 8wt% of sodium ethylenediaminetetraacetic acid, 10wt% of trisodium phosphate, 15wt% of sodium carbonate, and 5wt% of sodium hydroxide, pulverized and mixed evenly, diluted with 90% water and stirred evenly, and then packed into a barrel to prepare a medicine.

[0032] The above additives are used in a coal-fired boiler of a power plant. The dosage should be considered according to the water quality of the boiler. Add 0.2-0.4 kg of chemical per ton of water. Pump the liquid into the water supply pipe in proportion. After one cycle, measure the water quality.

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 ...
