Abstract
The invention relates to an ntiscaling boiler water treatment agent which comprises the following components in percentage by weight: 20-30 wt% of polyamine polyether methylene phosphonate, 20-30 wt% of copolymer of crylic acid/methyl acrylate, 3-18 wt% of HEDP, 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. By using the boiler water treatment agent provided by the invention, the hardness of boiler water can be lowered, and the formation of water scale is reduced and inhibited. After the boiler water treatment agent is used, the oxygen content of boiler water is within the national standard range. The boiler water treatment agent provided by the invention also has the actions of residue and hard scale elimination 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 deoxidizing method, 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.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 scale inhibition water treating agent for boilers, and its purpose is to provide a kind of 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 scale inhibition water treating agent for boilers is characterized in that: it is composed of the following components calculating it according to weight fraction:
Polyamino polyether methylene phosphoric acid 20-30wt%,
The multipolymer 20-30wt% of vinylformic acid/vinylformic acid formicester,
Hydroxy ethylene diphosphonic acid 3-18wt%,
Potassium sulfite 10-15wt%,
Ethylenediamine tetraacetic acid (EDTA) 2-8wt%,
Tertiary sodium phosphate 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:
Polyamino polyether methylene phosphoric acid 20wt%,
The multipolymer 20wt% of vinylformic acid/vinylformic acid formicester,
Hydroxy ethylene diphosphonic acid 9wt%,
Potassium sulfite 11wt%,
Ethylenediamine tetraacetic acid (EDTA) 6wt%,
Tertiary sodium phosphate 15wt%,
Yellow soda ash 15wt%,
With sodium hydroxide 4wt%.
Scale inhibition water treating agent for boilers of the present invention, wherein potassium sulfite has preferable deaerating effect; The multipolymer of polyamino polyether methylene phosphoric acid, vinylformic acid/vinylformic acid formicester and hydroxy ethylene diphosphonic acid are good Scale inhibitorss after mixing, and ethylenediamine tetraacetic acid (EDTA) 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 scale inhibition water treating agent for boilers has following beneficial effect:
(1) scale inhibition water treating agent for boilers of the present invention can make the boiler oxygen in water remove rapidly, solves the etching problem of boiler and pipeline, interchanger.
(2) scale inhibition water treating agent for boilers 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) scale inhibition water treating agent for boilers 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 11wt%; Polyamino polyether methylene phosphoric acid 20wt%; The multipolymer 20wt% of vinylformic acid/vinylformic acid formicester; Hydroxy ethylene diphosphonic acid 9wt%, ethylenediamine tetraacetic acid (EDTA) 6wt%, tertiary sodium phosphate 15wt%; Yellow soda ash 15wt%; With sodium hydroxide 4wt%, 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 90% and 85% 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.
