Water treating agent of boiler

Abstract

A boiler water treatment chemical consists of sodium hydrate, monometallic sodium orthophosphate, hydroxyl-ethylene phosphoric acid, ethylenimine, hydrazine, sodium humate, sodium sulfite, sodium phosphate and deionized water. It has better water quality and saves energy sources.

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 boiler water treatment agent. Background technique [0002] The equipment material of the boiler system is generally different from other industrial circulation equipment, and it is relatively easy to foul and often needs to be cleaned. At present, most of the existing pickling corrosion inhibitors are aimed at various circulation systems. When applied to boiler systems, their corrosion inhibition effects are greatly limited. [0003] A qualified boiler water treatment agent must effectively play the dual roles of scale and corrosion inhibition. Scale inhibition mainly refers to the scale inhibition of the boiler body, and the objects of corrosion inhibition include the boiler body and the pipes through which the steam passes, heat exchangers and condensate water pipes.

Problems solved by technology

Under acidic conditions, the corrosion of iron is greatly accelerated, and a large amount of iron dissolves into the condensed water, and sometimes the condensed water has to be drained. Due to the high temperature of the condensed water, this will inevitably cause a lot of waste of energy.
