Problems solved by technology

A high or low pH of the boiler water will cause harm to the safe operation of the boiler equipment: a low pH will cause acid corrosion in the feed water, return water, and drainage systems; Reduce the quality of air supply and endanger the safety of equipment
[0003] At present, the pH adjustment of industrial boiler feed water is mostly adjusted by ammonia water. This method has the following disadvantages: large dosage, high volatility of the product, great harm to the human body, and obvious attenuation after thermal deoxygenation

Abstract

The invention discloses a boiler pH regulator and application thereof. The boiler pH regulator comprises the following raw materials in percentage by mass: 5-15% of triethanolamine, 10-15% of octadecylamine, 10-25% of cyclohexylamine, 15-25% of diethylenetriamine and the balance of deionized water. The boiler pH regulator disclosed by the invention has the advantages of being small in usage amount, low in product volatility, simple in operation, less in harm to human bodies and excellent in heat stability, does not have obvious attenuation after thermal deaeration and has a certain corrosion inhibition performance, and the corrosion rate of a boiler system can be reduced, so that deposition of metallic corrosion products in the boiler is reduced, and boiler interior cleaning is facilitated. The boiler pH regulator disclosed by the invention can be applied to refinery enterprise boiler systems, power plants, chemical plants, caustic soda, papermaking and pharmacy.

Description

Technical field [0001] The invention relates to the technical field of boiler water treatment agents, specifically a boiler pH regulator and its use. Background technique [0002] Boilers are equipment that generate steam and hot water. The quality of boiler water has a great impact on the safe operation and efficiency of the boiler. The pH value is an important indicator, and its changes directly affect the safe and economical operation of boiler equipment. my country's current water quality standards for medium-pressure boilers stipulate that when steam boilers or hot water boilers are treated with chemical water in the pot or chemical water treatment outside the pot, the water quality standard pH (25°C) is greater than 7 for the feed water and 9-11 for the pot water. Boiler water pH that is too high or too low will cause harm to the safe operation of boiler equipment: if it is too low, it will cause acid corrosion to the water supply, return water, and drainage systems; i...
