Abstract
The invention relates to a multifunctional energy-saving water treatment agent for a boiler to deoxidize and block and prevent scale, comprising the following components by weight percent: 50-57 percent of catalytic sodium sulfite, 5-10 percent of 2, 3-diamino-piperidine, 3-8 percent of cyclohexane, 10-15 percent of trisodium phosphate, 20-25 percent of sodium carbonate and 5-8 percent of sodium hydroxide. The multifunctional energy-saving water treatment agent can reduce the rigidity of water in the boiler, quickly remove dissolved oxygen in the water, avoid the corrosion of the boiler, pipelines and a heat exchanger, control the oxygen content of the boiler water to be in a state standard range, reduce the water-quality discharge capacity and has the functions of removing residual hardness and preventing scale.
Description
Technical field
The invention belongs to the water purification technology field, be specifically related to a kind of multifunctional energy-saving water treatment agent that is used for boiler deoxidizing method, scale inhibition, antiscale.
Background technology
At boiler component (as boiler body, be arranged in the heat exchanger and the economizer at boiler body upwelling place and be arranged in boiler body following current place steam and condensate pipe) in, 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 as hydrazine, azanol group or carbohydrate etc.When using the azanol group to carry out chemical treatment, azanol can produce acid as 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 instrument for clean the boiler and antiscale, but the aforesaid method descale effect is all undesirable.
Summary of the invention
At the problems referred to above of prior art, the invention provides a kind of multifunctional energy-saving water treatment agent that can be used for boiler deoxidizing method, scale inhibition, antiscale.
For achieving the above object, the invention provides a kind of multifunctional energy-saving water treatment agent, it is to be grouped into by following one-tenth: catalyzed sodium sulfite 50-57 weight %, 2,3-diamino-piperidines 5-10 weight %, hexahydroaniline 3-8 weight %, tertiary sodium phosphate 10-15 weight %, yellow soda ash 20-25 weight % and sodium hydroxide 5-8 weight %.
Above-mentioned multifunctional energy-saving water treatment agent preferably is grouped into by following one-tenth: catalyzed sodium sulfite 55 weight %, 2,3-diamino-piperidines 6 weight %, hexahydroaniline 4 weight %, tertiary sodium phosphate 10 weight %, yellow soda ash 20 weight % and sodium hydroxide 5 weight %.
Multifunctional energy-saving water treatment agent of the present invention, wherein catalyzed sodium sulfite comprises S-WAT and Resorcinol, it has preferable deaerating effect; 2,3-diamino-piperidines plays katalysis in stove water oxygen removal process; Hexahydroaniline has corrosion inhibitive function; Tertiary sodium phosphate can form passive film on metal; Yellow soda ash and sodium hydroxide play the effect that increases the pH value.
Beneficial effect of the present invention is that multifunctional energy-saving water treatment agent of the present invention can make the boiler oxygen in water remove rapidly, solves the corrosion of boiler and pipeline, interchanger, and boiler water quality hardness is reduced, and reduces and stop the formation of incrustation scale.The oxygen level of using the back feedwater is in the national standard scope.The energy-conservation medicament of multi-functional processing of the present invention also has except that residual hard and anti-scaling action.
Embodiment
Embodiment 1
1. the preparation of multifunctional energy-saving water treatment agent:
With commercial catalyzed sodium sulfite 55 weight %, 2,3-diamino-piperidines 6 weight %, hexahydroaniline 4 weight %, tertiary sodium phosphate 10 weight %, yellow soda ash 20 weight % and sodium hydroxide 5 weight % mix after pulverizing, and add the even back barrelling of 90% water dilution and make medicament.
2. above-mentioned additive for fire coal is used for certain power station coal firing boiler.
Dosage is considered to press boiler water quality, and 0.2～0.5 kilogram of water adding medicine 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 are as shown in table 1.
