Abstract
The invention relates to a sulfur-fixing agent. The invention is characterized in that the sulfur-fixing agent comprises marl, which contains 35 to 44% of calcium oxide and is a waste material of limestone used in a cement plant, and a mineralizer composed of fluorite powder and/or waste residues discharged by a chemical plant and containing calcium chloride, wherein, the marl is used as a main material of the sulfur fixing agent, the fluorite powder contains 60 to 40% of calcium fluoride, and the waste residues contain 40 to 30% of calcium chloride. The sulfur-fixing agent provided in the invention enables a circulating fluidized bed boiler to have an optimal desulphurization effect and residues of combustion to be modified into a 100% highly efficiently used hydraulic cementing material in the boiler, and therefore, combustion thermal efficiency of the boiler is improved and the problem of coking in the boiler caused by coal combustion is overcome; an application method for the sulfur-fixing agent has the advantages of a simple process, high efficiency, environmental protection and convenient usage.
Description
Technical field
The present invention relates to a kind of fluid fuel, relate in particular to a kind of sulphur-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 sulphur-fixing agent; It is characterized in that: said sulphur-fixing agent by calcium oxide content by dead meal muddy limestone, fluorite powder and/or the chemical plant of the used Wingdale in cement mill of (35-44) % row contain mineralizer that the waste residue of calcium chloride forms, and be the sulphur-fixing agent of major ingredient with the muddy limestone; Wherein fluorite powder fluorinated calcium is (60-40) %, and it is (40-30) % that this waste residue contains calcium chloride.
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 sulphur-fixing agent by calcium oxide content by dead meal muddy limestone, fluorite powder and/or the chemical plant of the used Wingdale in cement mill of (35-44) % row contain mineralizer that the waste residue of calcium chloride forms, and be the sulphur-fixing agent of major ingredient with the muddy limestone; Wherein fluorite powder fluorinated calcium is (60-40) %, and it is (40-30) % that this waste residue contains calcium chloride.
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.
