Description
Technical field
The present invention relates to a kind of low-phosphorous retarding circulating water scaling corrosion inhibiter being suitable for using municipal middle water as moisturizing of environmental protection, belong to
In industrial circulating cooling water scale inhibitor processing technology field.
Background technique
Water is the natural resources of preciousness for the survival of mankind, and shortage of water resources has become worldwide hot topic.China
The occupancy volume of per capita water resource is about the 1/4 of world occupancy volume per person, is that world's per capita water resource is poorest after ranking hundred
One of country.Therefore, significant in China's water conservation, reasonable use of water.In local water-deficient area, water has become restriction
An important factor for industrial and agricultural development and threat safety in production.In industrial water there are about 50% it is used above with consumption in industry
On cooling water, so improving recirculated water concentration rate, reducing water amount of blowdown is the important channel for realizing that industrial production is water-saving.
Municipal middle water is used for industrial circulating cooling water system supplement water and has become a kind of important of effective use water resource
Approach, but since municipal middle water has the water quality characteristics such as high hard, high alkalinity, high sulfate radical, high organic matter, at present using in city
Water is generally lower as the circulation concentration rate of moisturizing, in addition using some with organic phosphine scale inhibition as main component
Agent can be such that total phosphorus content in recirculating water blowdown water increases considerably, give such as application No. is 200910148632.1 Chinese patent
Surrounding aqueous environment pollutes, and has certain environmentally friendly risk.Therefore to solve the above-mentioned problems, select a kind of efficient, environmental protection
Anti-incrustation corrosion inhibitor is just particularly important.
Summary of the invention
It is an object of the invention to overcome the above deficiencies in the existing technologies, and provide a kind of environmental protection it is low-phosphorous be applicable in
In the retarding circulating water scaling corrosion inhibiter using municipal middle water as moisturizing, the dense of the recirculated water using municipal middle water as moisturizing can be improved
Demagnification rate reduces water amount of blowdown.
Technical solution used by the present invention solves the above problems is: a kind of environmental protection it is low-phosphorous suitable for being made with municipal middle water
For the retarding circulating water scaling corrosion inhibiter of moisturizing, which is characterized in that the component including following parts by weight: poly-epoxy succinic acid (PESA)
2.0-2.3 part;2- phosphonobutane -1,2,1.6-1.8 parts of 4- tricarboxylic acids (PBTCA);Carboxylic acid-sulfonic-acrylic ester ternary polymerization
2.2-2.5 parts of object (AA-AMPS-HPA);Poly- 1.5-1.7 parts of citric acid (PCA);1.0-1.2 parts of zinc gluconate;Water 0.5-1.7
Part.
Medicament of the present invention is matched can be miscible with water, and (20 DEG C) of density are greater than 1.15g/cm3, solid content is greater than 32%, 1%
The pH of aqueous solution is between 3.0 ± 1.5, and for phosphonic acids salt content between 2.0-6.8%, finished medicament physical and chemical index meets DL/T
Regulation in 806-2013 " thermal power plant recirculated water anti-incrustation corrosion inhibitor " about low-phosphorus antiincrustation corrosion inhibitor.
Municipal middle water of the medicament of the present invention suitable for water hardness less than 15mmol/L and basicity less than 8mol/L, which is used as, to follow
The circulation scale inhibitor of ring water moisturizing uses.
Beneficial effects of the present invention are as follows: medicament of the present invention is with poly-epoxy succinic acid, carboxylic acid-sulfonic-acrylic ester ternary
Copolymer and poly- citric acid are host agent, compound a small amount of low phosphorous phosphonate and organic zinc salt, the scale inhibitor of collaboration enhancing medicament
Ability gives full play to drug effect.
Scale inhibitor agent prescription provided by the invention has the spies such as scale inhibitor effect is good, environment influence is small, adaptable
Point is suitble to add antisludging agent treatment process and the individually circulating water treatment process of addition antisludging agent using acid adding.It can be mentioned after use
The concentration rate of recirculated water of the height using municipal middle water as moisturizing reduces water amount of blowdown, and Reducing environmental impact saves water resource,
With good economic efficiency and social benefit.
By taking 2 × 600MW fired power generating unit as an example, the quantity of circulating water of 2 units is about 130000m3/ h, cooling tower evaporation loss
Amount is averagely about 1800m3/ h considers by 2.5 times of its recirculated water concentration rate, concentration rate can be made to mention using after medicament of the present invention
Height then saves more than 300 ten thousand tons of water of supplement to 4.0 times in year, saves about 20 tons of medicament, saves the expense about more than 560 ten thousand thus caused
(for water rate based on 1.8 yuan/ton, medicament is based on 1.2 ten thousand/ton), while large amount of sewage outlet is reduced, be conducive to water environment protection.
