Abstract
The present invention relates to a kind of briquette binder and method for making, it is to be made of by weight ratio following compositions: SODIUMNITRATE 20-50, magnesium chloride 10-30, sodium-chlor 10-20, ammonium chloride 5-20, light magnesium oxide 10-40, calcium oxide 5-20, Mierocrystalline cellulose 20-30.Advantage be cost low, can reach moulded coal desulfurization, waterproof, combustion-supporting, enhanced purpose simultaneously.
Description
Technical field
The present invention relates to a kind ofly be applied to moulded coal desulfurization, waterproof, combustion-supportingly be the binding agent of one and method for making.
Background technology
China is maximum in the world coal production state and country of consumption, owing to contain a large amount of sulfurous gas and dust in the flue gas that coal burning is discharged, caused great environmental pollution, China governments at all levels all attach great importance to problem of environmental pollution, and utilize various laws, rules to curb environmental pollution, also advocate each coal-fired enterprise simultaneously energetically and use low sulfur-bearing coal or use the environment protection clean moulded coal of handling through desulfurization to reduce coal-fired pollution to environment.Also have coal resources shortage in recent years, energy shortage has become whole society's Focal Point of Common Attention.In order effectively to solve the energy dissipation phenomenon, governments at all levels extremely pay close attention to briquette production and use, but moulded coal makes this New-type fuel of moulded coal can not get effectively promoting the use of producing, processing the restriction that has been subjected to several technical problems in using.The technical problem of restriction moulded coal development mainly contain following some:
1) moulded coal adds bonding component and has increased pit ash for moulding, makes moulded coal not on fire, and temperature of combustion is low, and calorific value descends, can not perfect combustion.
2) limit because of prior art and use cost and can't solve moulded coal waterproof, protection against the tide, make moulded coal in transportation, be restricted when storing.
3) because of moulded coal is the synthetic coal, frangible, breakage rate is high because ultimate compression strength, physical strength can not satisfy productions, transportation, storages, use desirable strength, waste and lose seriously.
4) because the process for processing cost is limit, effectively desulfurization causes environmental pollution.
Prior art can only singlely solve the problems referred to above, can not solve desulfurization in the briquette production, waterproof, combustion-supporting problem simultaneously.
Summary of the invention
The purpose of this invention is to provide a kind of cost low, can reach simultaneously moulded coal desulfurization, waterproof, combustion-supporting, strengthen and be the briquette binder of one and method for making.
A kind of briquette binder is characterized in that it is to be made of by weight ratio following compositions: SODIUMNITRATE 20-50, magnesium chloride 10-30, sodium-chlor 10-20, ammonium chloride 5-20, light magnesium oxide 10-40, calcium oxide 5-20, Mierocrystalline cellulose 20-30.
The method for making of described briquette binder, make by following steps:
1) above composition separated pulverizing is become the 60-350 order, by required weight part metering, stand-by;
2) after the weight part proportioning by the prescription requirement, above-mentioned raw materials is put into mixer, mix and stir, standby after mixing;
3) with the product of stirring and evenly mixing through after the assay was approved, the packing warehouse-in.
More than in each composition, SODIUMNITRATE, sodium-chlor, Mierocrystalline cellulose play combustion-supporting effect in reaction process, and make coal improve the combustion reactions activity, reach the abundant perfect combustion of moulded coal coal briquette; Magnesium chloride, sodium-chlor, light magnesium oxide, calcium oxide generate the glued composition of magnesia and play bonding, waterproof, enhancement in reaction process.Light magnesium oxide, calcium oxide play solid sulphur effect in reaction process, sulfurous gas reaction generation sal epsom, calcium sulfate in the fire coal are remained in the lime-ash, make fume emission reach environmental requirement.
Compared with prior art, the invention has the beneficial effects as follows:
1) use cost is low, and minute quantity increases the coal briquette ash content, does not influence the calorific value of feed coal, can improve coal briquette combustion reactions activity, quick combustion, and flame is long, and can burn cmpletely.
2) water resistance is strong, and coal briquette can soak oven dry in 8 hours in water after, ultimate compression strength reaches 810SSD (N/) and compares no considerable change with initial ultimate compression strength 808SSD (N/).In water, soak after 72 hours the spheroid no change.But coal briquette air storage is fully easily stored.
3) physical strength is 98.7%, and is not broken in production, transportation, storage, the use, do not have damaged loss.
Do not discharge black smoke when 4) coal briquette burns, have only a small amount of pearl opal flue gas to discharge, sulfur-fixing rate reaches more than 60%, is ideal energy-conserving and environment-protective products.
