Abstract
The invention relates to a preparation method for an efficient sulfur-fixing agent, which relates to the fields of circulating fluidized bed boiler combustion, desulfurization and ash modification. The efficient sulfur-fixing agent is burned together with coal, so that a hydraulic gelled material is generated; the calcium oxide content of marlite is (35-44) percent; and a mineralizer can be added into the marlite, and is a uniform mixture of a small amount of fluorite powder which contains (60-40) percent of calcium fluoride and calcium chloride-containing waste residues discharged by a chemical plant serving as auxiliary materials. Due to the adoption of the preparation method, an optimal desulfurization effect is achieved for a circulation fluidized bed boiler, burning residues can be modified into a 100 percent efficiently-utilized hydraulic gelled material in a furnace, the burning thermal efficiency of the boiler is increased, and the problem of coking in the furnace caused by coal burning is solved. A use method disclosed by the invention has the advantages of simple process, high efficiency, environmental friendliness and convenience for using.
Description
Technical field
The present invention relates to a kind of fluid fuel, relate in particular to a kind of preparation method of efficient sulfur-fixing agent.
Background technology
Coal water slurry be a kind of coal-based liquid state for oil fuel, be divided into conventional coal water slurry, Coal Slurry and low heat value coal water slurry.Why coal slurry fuel can replace oil, and its important characteristic can atomize rapidly for making coal water slurry as oil with pump delivery and atomizing rapidly in stove exactly, often needs the low coal water slurry of viscosity, and the low concentration that certainly will influence coal slurry of viscosity.Concentration is low, and unit volume heat energy just reduces, so " high density, LV " becomes technological difficulties.
Summary of the invention
The purpose of this invention is to provide that a kind of technology is simple, efficient, the preparation method of environmental protection, coal based fluid fuel easy to use.
For achieving the above object; The solution that the present invention adopts is: a kind of preparation method of efficient sulfur-fixing agent; It is characterized in that: described method comprises burning in circulating fluid bed boiler, solid sulphur and lime-ash modification, generates hydraulic cementing materials behind this efficient sulfur-fixing agent and the coal combustion; The basal component of said efficient sulfur-fixing agent is the dead meal of the used Wingdale in cement mill---muddy limestone, and this malmy calcium oxide content is (35-44) %; Said muddy limestone also can add mineralizer, this mineralizer by fluorite powder and/or chemical plant row contain the waste residue of calcium chloride, this fluorite powder fluorinated calcium is (60-40) %, it is (40-30) % that this waste residue contains calcium chloride; Said sulphur-fixing agent is to be major ingredient with the muddy limestone, and being arranged the waste residue that contains calcium chloride with a spot of fluorite powder and/or chemical plant is the uniform mixture that auxiliary material is formed.
The present invention makes circular fluid bed that best sweetening effectiveness arranged and can make the modification in stove of incendiary resistates become the 100% efficient hydraulic cementing materials that utilizes; The combustion thermal efficiency of boiler is improved; Also solved coking problem in the coal-fired stove that is brought, method of use technology of the present invention is simple, efficient, environmental protection, easy to use.
Embodiment
A kind of preparation method of efficient sulfur-fixing agent, described method may further comprise the steps:
Step 1: burning in circulating fluid bed boiler, solid sulphur and lime-ash modification generate hydraulic cementing materials behind this efficient sulfur-fixing agent and the coal combustion;
Step 2: the basal component of said efficient sulfur-fixing agent is the dead meal of the used Wingdale in cement mill---muddy limestone, and this malmy calcium oxide content is (35-44) %;
Step 3: said muddy limestone also can add mineralizer, this mineralizer by fluorite powder and/or chemical plant row contain the waste residue of calcium chloride, this fluorite powder fluorinated calcium is (60-40) %, it is (40-30) % that this waste residue contains calcium chloride; Said sulphur-fixing agent is to be major ingredient with the muddy limestone, and being arranged the waste residue that contains calcium chloride with a spot of fluorite powder and/or chemical plant is the uniform mixture that auxiliary material is formed.
The present invention makes circular fluid bed that best sweetening effectiveness arranged and can make the modification in stove of incendiary resistates become the 100% efficient hydraulic cementing materials that utilizes; The combustion thermal efficiency of boiler is improved; Also solved coking problem in the coal-fired stove that is brought, method of use technology of the present invention is simple, efficient, environmental protection, easy to use.
The above embodiment is not whole or unique embodiment of the present invention, and the conversion of any equivalence that those of ordinary skills take technical scheme of the present invention through reading specification sheets of the present invention is claim of the present invention and contains.
