Preparation method of environment-friendly boiler anti-scaling and scale-removing inhibitor

Abstract

The invention discloses a preparation method of an environment-friendly boiler anti-scaling and scale-removing inhibitor. The method comprises the following steps: adding smashed lignite, an extracting solution and sodium carbonate into a reaction kettle for reacting, and after the reaction is finished, standing and separating; extracting a clear solution, and feeding the extracted clear solution into a refining workshop; recycling non-reacted reactants by separating, and feeding reaction liquid into the refining workshop; evaporating the refined reactant, concentrating and drying; packaging dried products, metering and warehousing qualified products. The series of products provided by the invention integrates scale prevention, scale removal, corrosion inhibition and prevention of manual water loss, and a pioneer technology is created in China. The environment-friendly boiler anti-scaling and scale-removing inhibitor has the advantages of no toxicity, no pollution, no corrosion, excellent water solubility, high chemical stability, high temperature resistance, remarkable oxidation resistance, high complexing and chelating capabilities on metal ions such as calcium ions and magnesium ions in water, wide application range of water quality, and superior scale prevention and scale removal performance under severe environmental conditions.

Description

technical field [0001] The invention belongs to the field of corrosion inhibitors, in particular to a preparation method of an environment-friendly boiler anti-scaling, descaling and corrosion inhibitor. Background technique [0002] The development of boiler water treatment technology, from a certain safety performance to safety and economic performance, and then to safety, economy, and environmental protection performance, is the progress of society, the harmony and unity of human nature, and the need for sustainable development. Boiler water treatment includes boiler water treatment and boiler water treatment. Boiler water treatment chemicals are one of the earliest technologies applied to water treatment. From the perspective of its development history, it has generally gone through four development stages; it was originally used as a boiler water treatment product as a network formula. It started at the end of the 20th century and was an effective formula used by many ...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the embodiments of the present invention is to provide a preparation method of an environmentally friendly boiler anti-scaling, descaling and corrosion inhibitor, aiming to solve the problem that the existing technology cannot achieve industrial water treatment, boiler water treatment requires both anti-scaling and descaling, and ensures that the boiler and Its auxiliary equipment runs smoothly and safely; it also needs to prevent corrosion and prolong the service life of the equipment; it also needs to pay attention to environmental protection and energy saving and emission reduction, so it is difficult to grasp the perfect balance point
