Abstract
The invention relates to a multifunctional boiler water treatment agent, which is characterized by comprising the following components: 40-58 wt% of catalyzed potassium sulfite, 5-10 wt% of isoascorbic acid, 2-8 wt% of diethylenetriamine, 10-15 wt% of trisodium phosphate, 16-20 wt% of sodium carbonate and 5-8 wt% of sodium hydroxide. The multifunctional boiler water treatment agent of the invention can remove dissolved oxygen from boiler water rapidly, and solves the corrosion problem of boilers, pipelines and heat exchangers. The multifunctional boiler water treatment agent provided in the invention can also lessen the boiler water hardness, reduce and prevent scale formation, and employment of the treatment agent can control the boiler water oxygen content within the scope of national standards. The multifunctional boiler water treatment agent in the invention also has residual hard scale removing and scale prevention effects.
Description
Technical field
The invention belongs to the water purification technology field, relate in particular to a kind of multi-functional water treatment agent that is used for boiler deoxidizing method, scale inhibition, antiscale.
Background technology
[0002] 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.But boiler unavoidably fouling, rust can occur behind life-time service.In boiler component, the generation of the burn into incrustation scale of dissolved oxygen can influence the work-ing life of boiler, reduces heat transfer efficiency, wastes energy.For the generation of the burn into incrustation scale that stops dissolved oxygen, need remove the dissolved oxygen in the feedwater, reduce water hardness.
In the existing 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.Summary of the invention
The present invention has designed a kind of multi-function boiler water conditioner, and its purpose is to provide a kind of multi-functional water treatment agent that is used for boiler deoxidizing method, scale inhibition, antiscale.
To achieve these goals, the present invention has adopted following scheme:
A kind of multi-function boiler water conditioner; It is characterized in that: calculate it according to weight fraction and form: catalysis potassium sulfite 40-58wt%, saccharosonic acid 5-10wt%, diethylenetriamine 2-8wt% by following component; Tertiary sodium phosphate 10-15wt%, yellow soda ash 16-20wt% and sodium hydroxide 5-8wt%.
As preferred embodiment a kind of; It is to be grouped into by following one-tenth that multi-function boiler water conditioner of the present invention calculates it according to weight fraction: catalysis potassium sulfite 50wt%, saccharosonic acid 7wt%, diethylenetriamine 3wt%; Tertiary sodium phosphate 15wt%, yellow soda ash 20wt% and sodium hydroxide 5wt%.
Multi-function boiler water conditioner of the present invention, wherein the catalysis potassium sulfite comprises potassium sulfite and Resorcinol, behind the adding saccharosonic acid, it has preferable deaerating effect; Diethylenetriamine has good corrosion inhibitive function; Tertiary sodium phosphate can form passive film on metal; Yellow soda ash and sodium hydroxide play the effect of regulating the pH value.
This multi-function boiler water conditioner has following beneficial effect:
(1) multi-function boiler water conditioner of the present invention can make the boiler oxygen in water remove rapidly, solves the etching problem of boiler and pipeline, interchanger.
(2) multi-function boiler water conditioner 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.
(3) multi-function boiler water conditioner 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 catalysis potassium sulfite 50wt%; Saccharosonic acid 7wt%; Diethylenetriamine 3wt%; Tertiary sodium phosphate 15wt%; Yellow soda ash 20wt% and 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 0.2-0.5 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 90% and 80% respectively.
Combine specific embodiment that the present invention has been carried out exemplary description above; Obvious realization of the present invention is not subjected to 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.
