Abstract
The invention discloses a high-efficiency circulating water corrosion and scale inhibitor. The high-efficiency circulating water corrosion and scale inhibitor comprises 20-30% of HEDP, 15-35% of PBTC, 15-25% of AA/AMPS, 1-5% of sodium hexametaphosphate, 5-15% of zinc sulfate heptahydrate and 20-30% of water. The high-efficiency circulating water corrosion and scale inhibitor has the advantages that circulating water concentration multiple is increased, pollutant discharge is reduced, self-prepared cost price is 5 Yuan/kg which is more than half cheaper than that in the market, and the high-efficiency circulating water corrosion and scale inhibitor is better than those in the market and more suitable for application of Xijiang River water quality to a circulating water system.
Description
Technical field
The invention belongs to antisludging agent technical field, specifically, relate to a kind of efficient recirculated water corrosion inhibiting and descaling agent and compound method thereof。
Background technology
In recent years, the communication of China maintains the good momentum of sustained, rapid and sound development, highway construction develops very fast, highway and town and country Country Road Construction all achieve historical breakthrough, become the important booster of socio-economic development, development highway construction, not only increases transport capacity, and improving the investment climate, optimize industrial pattern etc. in all can produce important effect。
Along with developing rapidly of highway construction, on domestic market, the demand of Colophonium is increasing, it is desirable to also more and more higher。
Gao Fu company Circulating Water Field processes the water yield and is about 1500t/h, supplies full factory process units 20 multiple stage water cooler and uses。Since going into operation from 1998, due to improper with agent, the leakage of water cooler of oil plant in 1999 aggravates suddenly, leaks 1, within 2000, has 2 leakages, and there are 3 leakages calendar year 2001。From water cooler appraisal during calendar year 2001 general overhaul, system there is the tube bank of quite a few water cooler block, identify that the dirty sample analysis of components value of water cooler can be seen that Fe2O3Bigger than normal with 550 DEG C of content of organics。
Summary of the invention
Instant invention overcomes shortcoming of the prior art, provide a kind of efficient recirculated water corrosion inhibiting and descaling agent and compound method thereof, scale inhibition effect is good, and than cheap on the market more than half, and better than medicament on the market, be more suitable for the utilization in circulation of the Xijiang River water quality。
In order to solve above-mentioned technical problem, the present invention is achieved by the following technical solutions:
A kind of efficient recirculated water corrosion inhibiting and descaling agent, including following component: HEDP；PBTC；AA/AMPS；Sodium hexameta phosphate；Zinc sulphate heptahydrate；Water。
Further, HEDP20-30%；PBTC15-35%；AA/AMPS15-25%；Sodium hexameta phosphate 1-5%；Zinc sulphate heptahydrate 5-15%；Water 20-30%。
Further, according to weight ratio, HEDP23.5%；PBTC20%；AA/AMPS18%；Sodium hexameta phosphate 3%；Zinc sulphate heptahydrate 10.5%；Water 25%。
Its compound method, adds said components blender stirring, is initially charged water, adds PBTC, HEDP and AA/AMPS, be eventually adding zinc sulphate heptahydrate and sodium hexameta phosphate。
Compared with prior art, the invention has the beneficial effects as follows:
The efficient recirculated water corrosion inhibiting and descaling agent of one of the present invention, improve recirculated water cycles of concentration, decrease the discharge of pollutant, autogamy cost price is 5 yuan/kg, than cheap on the market more than half, and better than medicament on the market, be more suitable for the utilization in circulation of the Xijiang River water quality。
Detailed description of the invention
Hereinafter the preferred embodiments of the present invention are illustrated, it will be appreciated that preferred embodiment described herein is merely to illustrate and explains the present invention, is not intended to limit the present invention。
A kind of efficient recirculated water corrosion inhibiting and descaling agent, including following component:
According to weight ratio, HEDP23.5%；PBTC20%；AA/AMPS18%；Sodium hexameta phosphate 3%；Zinc sulphate heptahydrate 10.5%；Water 25%。
AA/AMPS is that acrylic acid forms with 2-acrylamide-2-methyl propane sulfonic (AMPS) copolymerization。
Its compound method, adds said components blender stirring, is initially charged water, adds PBTC, HEDP and AA/AMPS, be eventually adding zinc sulphate heptahydrate and sodium hexameta phosphate。
During overhaul, equipment qualification inspection, aqueous phase tube bank and end socket all occur without obvious corrosion, dirt, and the water cooler situation of inspection is substantially better than the domestic same device required level of service same period。Meanwhile, improve recirculated water cycles of concentration, decrease the discharge of pollutant。GF-4 corrosion inhibiting and descaling agent autogamy cost price is 5 yuan/kg, this proportioning than cheap on the market more than half, and better than medicament on the market, be more suitable for the utilization in circulation of the Xijiang River water quality。
Last it is noted that these are only the preferred embodiments of the present invention; it is not limited to the present invention; although the present invention being described in detail with reference to embodiment; for a person skilled in the art; technical scheme described in foregoing embodiments still can be modified by it; or wherein portion of techniques feature is carried out equivalent replacement; but all within the spirit and principles in the present invention; any amendment of being made, equivalent replacement, improvement etc., should be included within protection scope of the present invention。
