Abstract
The invention relates to a multifunctional water treatment agent which comprises the following components by weight: 15-30 wt% of polyepoxysuccinic acid, 15-30 wt% of polyacrylic acid, 6-18 wt% of acrylic acid/sulfo allylamine/maleic acid, 10-15 wt% of potassium sulfite, 2-8 wt% of ethylene diamine tetraacetic acid, 10-15 wt% of trisodium phosphate, 15-25 wt% of sodium carbonate, and 3-7 wt% of sodium hydroxide. The boiler water treatment agent of the invention can decrease boiler water hardness, reduce and prevent the formation of scale; with the water treatment agent, the oxygen content of boiler water is within national standard ranges; the boiler water treatment agent of the invention also has the functions of residual hardness removal and scale prevention.
Description
Technical field
The invention belongs to the water purification technology field, relate in particular to a kind of water treatment agent that is used for boiler scale-inhibition, antiscale.
Background technology
Boiler plant is the indispensable energy supply arrangement of industrial development, and it is big that it has a volume, installs, changes the characteristics that are difficult for, and therefore needs regular maintenance and cleaning, to delay its aging speed as far as possible.
In the present technology, often use the method for chemical treatment and physical treatment to remove dissolved oxygen.In chemical treatment, the oxygen scavenger that has been widely used is like sumptuous, light amine groups or carbohydrate etc.When using light amine groups to carry out chemical treatment, light amine can produce acid like nitric acid, thereby has increased the corrosion to boiler.And the defective of carbohydrate is to be difficult to measure its residue concentration in feedwater, thereby is difficult to control correct add-on, and carbohydrate runs into steam can produce foul smell.Usually adopt methods such as soda ash method, sodium ion exchange process, electronics antiscale appearance for clean the boiler and antiscale, but the aforesaid method descale effect is all undesirable.
Simultaneously, the Scale inhibitors that prior art provides has been obtained different effects in different application scenarios, but for high calcium, high sulfate radical, high dissolubility silicon water quality, does not also have satisfied Scale inhibitors product at present.Under above-mentioned condition of water quality, prevent and reduce the fouling on film surface, be the problem that presses for solution in the water treatment industry.
Summary of the invention
The present invention has designed a kind of multifunctional water treating agent, and its purpose is to provide a kind of water treatment agent that is used for boiler scale-inhibition, antiscale.
To achieve these goals, the present invention has adopted following scheme:
A kind of multifunctional water treating agent is characterized in that: it is composed of the following components calculating it according to weight fraction:
Poly-epoxy succinic acid 15-30wt%,
ROHM 15-30wt%,
The multipolymer 6-18wt% of vinylformic acid/sulfo group allylamine/toxilic acid,
Potassium sulfite 10-15wt%,
YD 30 is received 2-8wt%,
Tsp 10-15wt%,
Yellow soda ash 15-25wt%,
With sodium hydroxide 3-7wt%.
As a preferred embodiment of the present invention, it is composed of the following components calculating it according to weight fraction:
Poly-epoxy succinic acid 18wt%,
ROHM 22wt%,
The copolymer 1 2wt% of vinylformic acid/sulfo group allylamine/toxilic acid,
Potassium sulfite 10wt%,
YD 30 is received 8wt%,
Tsp 10wt%,
Yellow soda ash 15wt%,
With sodium hydroxide 5wt%.
Multifunctional water treating agent of the present invention, wherein potassium sulfite has preferable deaerating effect; The multipolymer of poly-epoxy succinic acid, vinylformic acid/sulfo group allylamine/toxilic acid and ROHM are good Scale inhibitorss after mixing, and YD 30 is received has good corrosion inhibitive function; Tsp can form passive film on metal; Yellow soda ash and sodium hydroxide play the effect of regulating the pH value.
This multifunctional water treating agent has following beneficial effect:
(1) multifunctional water treating agent of the present invention can also make boiler water quality hardness reduce, and reduces and stop the formation of incrustation scale, and the oxygen level of using the back feedwater is in the national standard scope.
(2) multifunctional water treating agent of the present invention also has except that residual hard and anti-scaling action.
Embodiment
Below in conjunction with embodiment, the present invention is further specified:
Embodiment 1
Calculating it according to weight fraction is to be grouped into by following one-tenth: buy commercially available potassium sulfite 10wt%, poly-epoxy succinic acid 18wt%, ROHM 22wt%; The copolymer 1 2wt% of vinylformic acid/sulfo group allylamine/toxilic acid, YD 30 receive 8wt%, tsp 10wt%; Yellow soda ash 15wt%; With sodium hydroxide 5wt%, mix after the pulverizing, add 90% the water dilution and the back barrelling that stirs and process medicament.
Above-mentioned additive is used for certain power station coal firing boiler.Dosage is considered to press boiler water quality, and water adding medicine 0.2-0.4 kilogram per ton adds water-supply pipe to soup with pump in proportion, and through measuring water quality after the circulation, deoxygenation rate and antiscaling rate reach 91% and 83% respectively.
Combine specific embodiment that the present invention has been carried out exemplary description above; Obvious realization of the present invention does not receive the restriction of aforesaid way; As long as the various improvement of having adopted method design of the present invention and technical scheme to carry out; Or design of the present invention and technical scheme are directly applied to other occasion without improving, all in protection scope of the present invention.
Claims (2)
