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

Example Embodiment

[0030] Example 1

[0031] Calculated according to weight fraction, it is composed of the following components: buy commercially available potassium sulfite 11wt%, polyaminopolyether group methylene phosphoric acid 20wt%, copolymer 20wt% of acrylic acid / methyl acrylate, hydroxyethylene diphosphine Acid 9wt%, ethylenediaminetetraacetic acid 6wt%, trisodium phosphate 15wt%, sodium carbonate 15wt%, and sodium hydroxide 4wt%, pulverized and mixed evenly, added 90% water to dilute and stirred evenly, then filled into barrels to make medicine .

[0032] The above additives were used in a coal-fired boiler in a power plant. The amount of medicine should be considered according to the water quality of the boiler. Add 0.2-0.4 kg of medicine per ton of water, pump the medicine solution into the water supply pipe in proportion, measure the water quality after a cycle, and the oxygen removal rate and scale prevention rate reach 90% and 85% respectively.

Abstract

The invention relates to an ntiscaling boiler water treatment agent which comprises the following components in percentage by weight: 20-30 wt% of polyamine polyether methylene phosphonate, 20-30 wt% of copolymer of crylic acid/methyl acrylate, 3-18 wt% of HEDP, 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. 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 invention belongs to the technical field of water quality purification, and in particular relates to a water treatment agent for boiler deoxidation, scale inhibition and scale prevention. 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. However, after the boiler is used for a long time, fouling and rust will inevitably occur. In the boiler components, the corrosion of dissolved oxygen and the generation of scale will affect the service life of the boiler, reduce the heat transfer efficiency and waste energy. In order to prevent the corrosion of dissolved oxygen and the generation of scale, it is necessary to remove the dissolved oxygen in the boiler water and reduce the hardness of the water. [0...
