Boiler pickling agent and preparation method thereof

Abstract

The invention discloses a boiler pickling agent and a preparation method thereof and belongs to the field of boiler washing. The boiler pickling agent is prepared from the following components in percentage by weight: 2 percent to 10 percent of EDTA (Ethylene Diamine Tetraacetic Acid), 1 percent to 7 percent of ammonia water, 2 percent to 10 percent of citric acid, 0.5 percent to 5 percent of benzylhexadecyldimethylammonium chloride, 0.1 percent to 0.3 percent of sodium dodecyl benzene sulfonate, 0.2 percent to 2 percent of hydrazine hydrate, 0.1 percent to 0.3 percent of sodium silicate, 0.3percent to 1 percent of urotropine and 60 percent to 80 percent of water; the product can be prepared by adding the components into a liquid stirrer according to a certain sequence and uniformly mixing. The invention aims at providing the boiler pickling agent which is stable in performance and strong in washing capability; meanwhile, the preparation method has the advantages of simplicity, easiness of obtaining raw materials, small damages to the environment and convenience for utilization and operation.

Description

technical field [0001] The invention belongs to the field of boiler cleaning, and in particular relates to a boiler pickling agent and a preparation method thereof, which are used for efficiently removing rust and carbonate scale inside the boiler. Background technique [0002] At present, most boilers will have scaling phenomenon on the water side during operation. Scaling of water-cooled wall tubes will seriously affect the heat exchange efficiency of the boiler, increase coal consumption, and increase the operating cost of the boiler. At the same time, scaling will seriously affect the operation safety of the boiler. , It will cause the boiler water-cooled wall tube to burst, cause the boiler to be shut down for maintenance, and cause a lot of economic losses. Scaling on the boiler water side has become one of the major problems in boiler operation. [0003] At present, for the scaling problem on the water side of the boiler, most of them will use a single inorganic acid ...

Problems solved by technology

[0002] At present, most boilers will have scaling on the water side during operation. Scaling of water-cooled wall tubes will seriously affect the heat transfer efficiency of the boiler, increase coal consumption, and increase the operating cost of the boiler. At the same time, scaling will seriously affect the operating safety of the boiler. , will cause the boiler water wall tube to burst, cause the boiler to be shut down for maintenance, and cause a lot of economic losses. Scaling on the water side of the boiler has become one of the major problems in the operation of the boiler

[0003] At present, for the scaling problem on the water side of the boiler, most of the shutdown cleaning will use a single inorganic acid or organic acid, etc., which will cause corrosion of the boiler and affect the service life and operation safety of the boiler.
