[0004] More importantly, after research, it is found that phosphorus elements will cause red tides, because a large amount of phosphorus, nitrogen and other elements will make seawater trophic, causing algae to multiply, resulting in the continuous expansion of algae plants, making marine animals hypoxic (because algae Dissolved oxygen is needed for reproduction, and a large area of ​​algae separates the atmosphere from water), eating poisonous algae by mistake, etc., r

Abstract

The invention discloses an environment-friendly efficient boiler water regulator for a drum boiler. The water regulator comprises, by mass, 65-90% of organic amine polymer, 10-30% of organic hydrazide compound and 1-5% of tungstate. The boiler water regulator disclosed by the invention can prevent and control the influence of acidic water quality on a system, can provide comprehensive protection for a boiler water supply system and a steam condensation water system, and does not generate a local amine enrichment phenomenon even if the pH value of the water system reaches about 10; corrosion of residual dissolved oxygen to pipelines and equipment can be effectively prevented, and a passivation effect is achieved; the boiler water regulator used in the invention can also effectively relieve the pipeline scaling phenomenon; and boiler water treated by the boiler water regulator for the environment-friendly and efficient drum boiler can be put into use after being settled, and the operation is simple and convenient.

Description

technical field [0001] The invention relates to the field of drum boiler additives, in particular to an environment-friendly and high-efficiency drum boiler boiler water conditioner. Background technique [0002] With the development of my country's economy, drum boilers are widely used in the boiler heating system of natural gas treatment plants, but there will be many problems in the process of use. Among them, due to the water in the drum boiler Pipes, headers and downcomers are circulated in the system, so the poor quality of boiler water may cause scaling, corrosion and salt accumulation problems to thermal equipment, which seriously affect the use of equipment. When the scaling problem occurs, it will lead to an increase in coal consumption. In addition, the cooling effect of the water is not good, which will cause the pipe to bulge or burst when the heating temperature is too high, which will shorten the service life of the boiler; Reducing the amount of water, again ...
