High-pressure boiler water treatment agent and application thereof

Abstract

An embodiment of the invention discloses a high-pressure boiler water treatment agent and application thereof. The high-pressure boiler water treatment agent comprises, by weight, 40-75 parts of monoethanolamine, 3-20 parts of sodium polyaspartate, 2-20 parts of hydroxyethylidene and 130-330 parts of ultrapure water. The application includes adding the high-pressure boiler water treatment agent into high-pressure boiler water. The high-pressure boiler water treatment agent and the application in the embodiment of the invention have the advantages that the high-pressure boiler water treatment agent is a multifunctional treatment agent with total organic polymers, efficient dispersing agents, auxiliaries and the like; hard scale in the boiler water can be chelated and dispersed by the aid ofserial reaction, scaling and potential corrosion due to general deposition of iron, copper and the like on parts of boiler tubes can be prevented, the problem of pipeline and valve corrosion can be solved, scaling and deposition of the boiler water can be effectively controlled, boiler water entrainment can be prevented, the concentration multiples can be increased, pollution discharge can be reduced, and the quality of steam can be improved.

Description

technical field [0001] The invention relates to the technical fields of chemical industry and environmental protection, in particular to a high-pressure boiler furnace water treatment agent and its application. Background technique [0002] High-pressure boiler equipment is an indispensable energy supply equipment for industrial development. It has the characteristics of large volume and difficult installation and replacement. Therefore, it needs regular maintenance and cleaning to delay its aging speed as much as possible. [0003] Corrosion and scale adhesion shorten the life of the boiler unit and reduce the thermal conductivity of the boiler, which hinders stable operation. Due to the limitation of the boiler system on the condition of feed water, most boilers use demineralized water or demineralized water as make-up water. The hardness of make-up water is low, and metal corrosion is very easy to occur during the operation of the boiler system. Incomplete boiler water ...

AI Technical Summary

Problems solved by technology

Boiler corrosion not only shortens the service life of the equipment itself and causes economic losses, but also increases the impurities in the water due to the metal corrosion products entering the water, which intensifies the scaling process on the heating surface with high heat load, which in turn aggravates the corrosion of the boiler

Therefore, boiler corrosion problems will seriously affect the safe and economical operation of boiler equipment.

The traditional control method is the collaborative control method of sodium phosphate and oxygen scavenger. This control method greatly increases labor consumption, increases the production cost of the enterprise, and reduces the efficiency of the enterprise.
