Novel power plant cooling water scale inhibitor corrosion inhibitor

Abstract

The invention discloses a novel power plant cooling water scale inhibitor corrosion inhibitor. The novel power plant cooling water scale inhibitor corrosion inhibitor is prepared from the following raw materials: acrylic acid, methyl acrylate, cis-butenedioic acid, 2-itaconic acid, ammonium persulfate and sodium hydrogen sulfite. Compared with the prior art, the novel power plant cooling water scale inhibitor corrosion inhibitor has the following advantages: in the prior art, the scaling problem of the power plant cooling water system cannot be thoroughly solved, which results in the scaling of the system; the scaling of a power plant steam condenser directly increases the terminal temperature difference and decreases the vacuum degree, and the power generation cost is increased; after anoil cooler is scaled, the temperature of a whole lubricating oil system is high, and the scaling of an air cooler influences the air cooling temperature; the scaling of a cooling tower filler influences the cooling effect of a cooling tower; the problems in the prior art increase the power generation cost of a power plant and influence the operation stability of the power plant; Zhongrui 863 scale-inhibition corrosion inhibitor thoroughly solves the scaling problem of the power plant cooling system, and the power plant cooling system is operated at an optimum state; and the power generation cost is maximally reduced, the stable operation time can be prolonged, and the scales do not need to be cleaned after the power failure.

Description

technical field [0001] The invention relates to the technical treatment field of scale inhibition and corrosion inhibition technology for cooling circulating water, and more specifically relates to a novel scaling and corrosion inhibitor for cooling water in power plants. Background technique [0002] Scale and corrosion inhibitors are composed of organic phosphine, high-quality copolymers and copper corrosion inhibitors. They have excellent corrosion inhibition performance on carbon steel, copper and copper alloys, and excellent scale and dispersion performance on calcium carbonate and calcium phosphate. This product is mainly used in open circulating cooling water treatment systems, especially suitable for systems containing copper equipment. [0003] At present, there are many scale and corrosion inhibitors available, but the common problem is that the scale inhibition efficiency is low, and the scale inhibition rate cannot be 100%, and all of them are slowly scaling duri...

Problems solved by technology

[0003] At present, there are many scale and corrosion inhibitors available, but the common problem is that the scale inhibition efficiency is low, and the 100% scale inhibition rate cannot be achieved, and all of them are slowly scaling during operation.

In order to increase the scale inhibition effect, concentrated sulfuric acid will be used for alkali reduction and solubilization. Excessive use of sulfuric acid will increase the corrosion rate
