Embodiment Construction

[0021] The anti-scaling agent is divided into dry powder and water agent. The three components in the dry powder and the first three components in the water agent are mainly used for medium and low pressure boilers, and the fourth component in the water agent is mainly used for high-pressure boilers. . The ingredients in the components are all available in the market.

[0022] The present invention is used for the alkaline multi-element anti-scaling agent for medium and low pressure boilers and the compound anti-scaling agent for polymaleic anhydride ethylene diammonium tetramethylene phosphate sodium composite anti-scaling agent for high-pressure furnaces. The agent integrates anti-scaling and anti-corrosion. At the same time, a smooth protective film is formed inside the furnace body, which hinders the corrosion of metal by hydrogen and oxygen molecules. After testing, the anti-scaling rate of the traditional method is 79%, and the anti-scaling rate of the medicament develo...

Abstract

The antiscale cleaning agent for boiler is divided into two kinds of dry powder and aqueous solution. Its dry powder components includes sodium carbonate, sodium humate, calgon and sodium phosphate, and its aqueous solution preparation composition includes sodium carbonate, sodium humate, calgon, sodium phosphate and water; polymaleic anhydride, sodium ethylenediamine tetramethylidene phosphate and water, its antiscale pH value is 8-10, and its cleaning pH value is 10-12. Said antiscale cleaning agent is applicable to various boilers.

Description

technical field [0001] The invention relates to an anti-scale and descaling agent for medium and low pressure boilers and high pressure boilers. Background technique [0002] At present, a large number of boilers are used in industry and civil use, of which high-pressure boilers account for 1 / 3, medium and low-pressure boilers account for 2 / 3, and the serious damage to boilers is the scaling problem, especially medium and low-pressure boilers (including hot water boilers). After fouling, the service life is shortened, thermal efficiency is affected, and energy is wasted. In order to prevent boiler scaling or descaling, traditional soda ash method, sodium ion exchange method, electronic anti-scaling instrument and other methods are mostly used, and each boiler needs to be pickled 1-2 times a year. Contents of the invention [0003] The purpose of the present invention is to provide a boiler anti-scaling agent in order to overcome the deficiencies of t...
