Phosphorus-free green environment-friendly water treatment agent for hot water boiler

Abstract

The invention discloses a phosphorus-free green environment-friendly water treatment agent for a hot water boiler. The phosphorus-free green environment-friendly water treatment agent comprises the following components in percentage by weight: 20-24% of maleic anhydride, 10-20% of ammonia water, 10-15% of disodium ethylene diamine tetraacetate, 13-18% of sodium polyaspartate, 10-12% of sodium hydroxide, 0.1-0.2% of a copper corrosion inhibitor, 3-6% of an auxiliary agent, 0.5-0.7% of imidazoline and 20-34% of water. According to the phosphorus-free green environment-friendly water treatment agent for the hot water boiler, the problems of boiler pipe explosion, pipe network leakage and the like caused by scaling of the boiler and a heat supply pipe network can be solved, water scales in a system are removed, formation of new scales is avoided, and metal corrosion of the system is slowed down; the product is a non-phosphorus green environment-friendly water treatment agent, and secondary pollution caused by water eutrophication and emission is avoided; and the device can replace softened water treatment equipment to directly soften water, so that water quality, hardness and other indexes meet national standard requirements, and a better use prospect is brought.

Description

technical field [0001] The invention relates to the field of boiler and circulating water treatment agent technology and water softening treatment, in particular to a phosphorus-free, green and environment-friendly hot water boiler water treatment agent. Background technique [0002] At present, my country's heat pipe network and boiler heat transfer medium are generally circulating water. The water quality is different in different parts of the country, and the content of calcium, magnesium and other salts in the water is different, and after heating, it precipitates and bonds to the metal surface to form scale. The thermal conductivity of scale is very small, which will deteriorate the heat transfer effect, reduce the heat transfer efficiency, cause local overheating of the boiler tube wall, and even cause tube explosion and corrosion under the scale of the tube network to cause leakage; [0003] Due to the structural characteristics and operation requirements of the pipe ...

AI Technical Summary

Problems solved by technology

The heating industry does not know enough about the quality and function of chemicals. They think that the effect of anti-corrosion and scale inhibitors is very small, and there is still time to deal with problems in the pipe network and boilers, or wait until the boiler bursts and replaces the pipes. The way to find the buried heating network pipeline and replace the pipeline will cause a waste of manpower and material resources, and more seriously affect the heating supply, which will rise to the issue of people's livelihood

Adding inappropriate anti-corrosion and anti-scaling agents will not only fail to achieve the effect of anti-corrosion and anti-scaling, but also may cause secondary scaling, which will further reduce the heat exchange efficiency of boilers and plate exchanges, and in severe cases will cause boiler tube bursts and pipe network leakage , affect the heating of the area, cause the loss of national property and the inconvenience of residents' lives, and do not meet people's requirements. For this reason, we propose a non-phosphorus, green and environmentally friendly hot water boiler water treatment agent
