Embodiment 1-6

[0024] Table 1 embodiment 1-6 steam boiler water treatment medicament formula and use effect

[0025]

[0026] 1. Preparation of steam boiler water treatment chemicals:

[0027] Ethylenediaminetetramethylenephosphonic acid, 2-phosphonobutane-1,2,4tricarboxylic acid (PBTC), sodium humate, extract and monoethanolamine, nitrogen tetrasubstituted phenylenediamine (TMPD) and sodium sulfite Mix with the mass percentage shown in Table 1, make up to 100% with water.

[0028] 2. The scale and corrosion inhibition performance of steam boiler water treatment chemicals is evaluated by the dynamic method of "Evaluation Method for Boiler Water Treatment Agent Performance" in the chemical industry standard HG / T3924-2007 of the People's Republic of China. In this standard, see Table 2 and Table 3 for the water quality indicators of scale inhibition performance test feed water preparation and corrosion inhibition performance test feed water preparation water.

Abstract

The invention discloses a steam boiler water treatment agent which comprises the following components by mass: 0.6-0.8% of organic phosphate, 1.4-2.0% of a carboxylate corrosion-inhibiting scale-inhibiting dispersant, 0.4-0.6% of sodium humate, 0.2-0.4% of monoethanolamine, 0.4-0.5% of N,N,N',N'-tetra-substituted phenylenediamine, 0.6-0.8% of a deoxidant, and water, and also comprises 0.2-0.3% of tannin extract and / or chitosan, and the balance of water. The invention also discloses a preparation method and an application method of the agent; the preparation process is clean; the application process has less toxicity on human health and environment; the agent is biodegradable, and has no harm to environment. The steam boiler water treatment agent of the invention not only has the effects of inhibiting scale in the boiler water system, and inhibiting corrosion of the steam and condensed water system, but also is simple and convenient for storage and transportation, and the corrosion inhibition and scale inhibition effects are not reduced after long-time storage and transportation.

Description

technical field [0001] The invention relates to the field of water treatment medicaments, in particular to steam boiler water treatment medicaments and their preparation and use methods. Background technique [0002] During the operation of the steam boiler, due to the high temperature and pressure of the furnace tube wall, the stress on each part of the equipment is great. If the water quality is poor, the impurities in the water will concentrate and precipitate in the boiler to form deposits, which will cause fouling of the water vapor system, Faults such as salt accumulation and metal corrosion will also lead to the deterioration of the quality of the superheated steam of the boiler, affect the normal operation of the steam turbine, and may cause the boiler tube to burst. [0003] In actual operation, chemical treatment method is usually used to treat boiler water, that is, adding appropriate chemical agent to boiler feed water to achieve the purpose of preventing boiler ...
