Problems solved by technology

If the water quality of the feed water is poor, the hazards are as follows: 1. Scale formation: Scale causes damage to the metal on the heating surface of the boiler, reducing the service life of the boiler; reducing the flow section in the heating tube, increasing the flow resistance of the water circulation in the tube; reducing thermal efficiency, Increase coal consumption or reduce boiler output; 2. Lead to boiler metal corrosion: Excessive use of cleaning agents, which contain more neutral salts, will cause metal corrosion; steam phenomenon, polluted steam
[0003] In general, if there is a problem with the water quality of the feed water, it will consume more energy to generate steam or hot water, and it will cause corrosion of the boiler and deterioration of steam quality. However, at this stage, cleaning agents for boiler water treatment are generally clean Insufficient and low cleaning efficiency, so an energy-saving synergist for boiler water treatment is needed to solve the problems caused by poor boiler feed water quality

Abstract

The invention discloses an energy-saving synergist for boiler water treatment and belongs to the technical field of boiler water treatment. The energy-saving synergist for boiler water treatment comprises the following raw materials in parts by weight: 10-20 parts of polyaspartic acid, 10-20 parts of 3-acrylamide dopamine, 5-10 parts of pH regulator, oxygen scavenger 3‑8 parts, 5‑10 parts of reinforcing components, 60‑70 parts of deionized water; wherein the reinforcing components are obtained by modifying guar gum with a modifier, and then oxidized, and the reinforcing components have quaternary ammonium salt side chains , can adsorb negatively charged ions and microorganisms, and after cross-linking and oxidation, the hydrogen bond interaction inside the molecule is reduced, making the network structure more expanded, and the effect of net capture and flocculation is better. It can be used in conjunction with other base materials to make The water treatment effect is better, the speed is faster, the energy consumption is reduced, and it has a good energy-saving and efficiency-enhancing effect.

Description

technical field [0001] The invention relates to the technical field of boiler water treatment, in particular to an energy-saving synergist for boiler water treatment. Background technique [0002] Boilers are steam or hot water generating equipment, and water is used as the heat transfer medium. Therefore, the quality of feed water is the core technology, and the use of qualified water quality is the prerequisite for ensuring the safe and stable operation of the boiler and the output of qualified steam or hot water. If the water quality of the feed water is poor, the hazards are as follows: 1. Scale formation: Scale causes damage to the metal on the heating surface of the boiler, reducing the service life of the boiler; reducing the flow section in the heating tube, increasing the flow resistance of the water circulation in the tube; reducing thermal efficiency, Increase coal consumption or reduce boiler output; 2.
