Description
Technical field
The present invention relates to a kind of corrosion inhibiting and descaling agent, specifically, is related to a kind of environmental-protection circulating water corrosion inhibiting and descaling agent.
Background technology
The wretched insufficiency of water supply will influence normal production and living, have a strong impact on expanding economy.
In order to alleviate the contradiction of shortage of water resources and economic growth, recirculated cooling water is the rich and influential family of industrial water, with
The concentration of circulating cooling impurities in water, cause recirculating cooling water system that the outstanding problems such as fouling, corrosion and biofouling occur,
The thermal efficiency is declined in the order of magnitude, not only waste mass energy, and because pipeline, equipment etc. are got rusty, greatly reduce whole
The service life of individual system.
The corrosion inhibiting and descaling agent of single compound is difficult to be fully solved simultaneous corrosion and fouling barrier in water treatment system
Hinder, it is difficult at the same in solution system more materials that may be present etching problem, it is necessary to utilize collaboration between various medicaments to increase
Effect acts on, and to meet the design requirement of water treatment system, ensures the normal continuous operation of system.
Domestic industry recirculated cooling water uses phosphorus line formulation mostly at present, adds expense to subsequent wastewater treatment, and make
Into secondary pollution.With the discharge standard more and more higher of environmental protection, the Con trolling index of total phosphorus is less and less, the application of phosphorus line formulation
Limited by environmental protection.
The content of the invention
Instant invention overcomes in the prior art the shortcomings that, there is provided a kind of environmental-protection circulating water corrosion inhibiting and descaling agent, scale inhibition
Effect is good, ensures the normal continuous operation of system, and reduces the discharge of phosphorus, avoids the pollution of phosphorus.
In order to solve the above-mentioned technical problem, the present invention is achieved by the following technical solutions：
A kind of environmental-protection circulating water corrosion inhibiting and descaling agent, including following component：HEDP, PBTC, AA/AMPS, DTPMP, zinc and
Water.
Further, including following component：According to mass ratio, HEDP 5-15%, PBTC 5-15%, AA/AMPS 15-
25%th, DTPMP 5-15%, zinc 2-10% and water 30-50%.
Further, including following component：According to mass ratio, HEDP 10%, PBTC 10%, AA/AMPS 20%,
DTPMP 10%, zinc 5% and water 45%.
Further, compound method is：By said components add mixer stirring, first add water, add HEDP, PBTC,
AA/AMPS, DTPMP, zinc.
Further, it is 60mg/L to add concentration.
Compared with prior art, the beneficial effects of the invention are as follows：
(1) corrosion inhibition is stronger, and test tube and lacing film surface cleaning, no spot corrosion and corrosion, corrosion rate is in normal water quality bar
Part is issued to fine rank, and rank has been issued in harsh condition of water quality.
(2) there are excellent scale-inhibiting properties, under conditions of cycles of concentration is 4.5-5.5, it adheres to speed in normal water
Reach fine rank under matter and harsh condition of water quality.
(3) there is stronger water resistant matter pollution capacity, still can be with control corrosion rate and fouling under harsh condition of water quality.
Embodiment
The preferred embodiments of the present invention are illustrated below, it will be appreciated that preferred embodiment described herein is only used
In the description and interpretation present invention, it is not intended to limit the present invention.
Environmental-protection circulating water corrosion-mitigation scale-inhibition agent prescription
AA/AMPS is that acrylic acid forms with 2- acrylamide-2-methyl propane sulfonics (AMPS) copolymerization.
1st, it is as follows to be formulated static test situation：
Note：Adding of agent concentration is 60mg/L.
2nd, it is formulated dynamic analog test
Note：Test water quality：1. normal water quality is-water source Xin Shui；2. harsh water quality is the-new water repairing 50mg/L in water source,
Total iron 1.5mg/L.
3rd, industrial amplification test
| Time | Corrosion rate mm/a | Adhere to speed mcm |
| 2016 | 0.050 | 4.24 |
| The first quarter in 2017 | 0.006 | 5.05 |
| The second quarter in 2017 | 0.033 | 2.90 |
| The third season in 2017 | 0.002 | 0.56 |
| Run overall average | 0.023 | 3.19 |
Note：It is 60mg/l to add concentration.
Run conclusion
By practice more than a year, during overhaul in May, 2017, equipment qualification inspection, aqueous phase tube bank and end socket are without bright
Aobvious corrosion, dirt occur, the water cooler situation of inspection is substantially better than domestic same device same period required level of service, it was demonstrated that from
The corrosion inhibiting and descaling agent matched somebody with somebody is more suitable for company's water quality, circulating water quality is formd benign cycle, reduces the discharge of phosphorus, avoids
The pollution of phosphorus.
Finally it should be noted that：The preferred embodiments of the present invention are these are only, are not intended to limit the invention, to the greatest extent
The present invention is described in detail with reference to embodiment for pipe, and for those skilled in the art, it still can be to preceding
State the technical scheme described in each embodiment to modify, or equivalent substitution is carried out to which part technical characteristic, but it is all
Within the spirit and principles in the present invention, any modification, equivalent substitution and improvements made etc., it should be included in the guarantor of the present invention
Within the scope of shield.
