Medicament for treating composite water in hot water boiler as well as preparation method and use method thereof

Abstract

The invention discloses a medicament for treating composite water in a hot water boiler. The medicament comprises the following components by mass percent: 0.1-3% of inorganic phosphate, 0.1-2% of organic phosphoric acid and / or organic phosphate, 0.1-4% of component A, 0.1-3% of component B, 0.6-1.0% of organic amine deoxidizer, 0.1-2% of tannin and / or chitosan and the balance of water, wherein the mass percent of the components is 100%, the component A is one or more of an organic antisludging agent, an organic dispersant and an organic dispersible antisludging agent, and the component B is one or more of an organic carboxylic acid corrosion inhibitor, an organic carboxylate corrosion inhibitor and sodium methylene dinaphthalenesulfonate. The invention further discloses a preparation method and a use method of the medicament, the preparation process is clean, and the medicament is low in toxicity for body health and environment in the using process. The medicament is excellent in corrosion resistance and scale inhibition effects and simple and convenient to store and transport, and the corrosion and scale inhibition effects cannot be reduced after the medicament is stored and transported for a long term.

Description

technical field [0001] The invention relates to a composite water treatment agent for a hot water boiler, a preparation method and a use method thereof. Background technique [0002] With the advocacy of a resource-saving society, energy saving and cost reduction of boilers have also been put on the new agenda. In the reclaimed water system such as cooling water system, boiler water system and exhaust dust water system, there is a requirement to save water. For this reason, in recent years, researchers have devoted themselves to developing technologies that can reduce the amount of water overflowing the system and operate at high concentrations. [0003] During the use of the hot water boiler, after the feed water containing impurities (mainly hardness components) enters the boiler, due to the high concentration of scale components such as calcium and magnesium in the water, when it reaches saturation through continuous evaporation and concentration, the solid Deposits are...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to overcome the problem that traditional phosphate water treatment agents are mixed with tannin oxygen scavengers to form insoluble salts, reducing the descaling effect, and traditional boiler deoxidizers are harmful to the human body and the environment and are difficult to degrade To deal with the defects, provide a hot water boiler composite water treatment agent and its preparation method and use method
