Multifunctional water-treating antisludging agent of boiler

Abstract

A multifunctional boiler water treatment scale inhibitor consists of 1-amino-pyrrolidine, monometallic sodium orthophosphate, sodium sulfite and ethylenimine and deionized water. It has wide pH range and better dispersion ability, it can control scale effectively under the conditions of high-hardness, high-iron content, high-base content, high-pH and high-temperature.

Description

technical field [0001] The invention belongs to the fields of chemical industry and water treatment, and relates to a water treatment agent. Furthermore, the invention relates to a multifunctional scale inhibitor for boiler water treatment. Background technique [0002] After long-term use of equipment such as boilers, scaling and corrosion will inevitably occur. Scaling control is a major mission of industrial water treatment. Scaling control is to control the calcium carbonate scale produced due to "instability" in the process of industrial water operation, and the barium sulfate and strontium sulfate scale produced due to "incompatibility". Since polyphosphate, phosphate and zinc salt are used as the Calcium phosphate or zinc phosphate scale formed by the combination of corrosion inhibitor and calcium in water, as well as iron oxide scale due to corrosion, sedimentation and scaling caused by the introduction of sediment, and microbial proliferation caused by microbial ba...

AI Technical Summary

Problems solved by technology

Although these antiscalants can solve the scaling problem of industrial water treatment to a certain extent, there are still many defects, such as their low tolerance to calcium in water, and the ability to inhibit scale in iron-containing and oil-containing water. Compounding and compatibility with other water treatment corrosion and scale inhibitors are unsatisfactory, etc.
