Abstract
This invention discloses a binding material for producing industrial waterproof briquette capable of being pressurization-gasified without drying process. The binding material is powdery, and is formed by: pulverizing Sorel cement 50%, bentonite 15%, steel slag 20%, and graphite tailing 10%, and trisodium phosphate 5%, and mixing. The briquette produced from the binding material has such advantages as high cold strength, good waterproof property, convenient transportation, low cost, simple process, convenient maintenance, high thermal stability, high gasification rate, and good sulfur-fixation effect. The binding material can solve the problems of low waterproof capacity, low gasification rate, low combustion efficiency, low thermal strength and no air permeability faced by conventional briquette.
Description
Affiliated technical field
The present invention is to coal in gasified industry type gas making continuously in producer gas generator, the binding agent of moulded coal air storage waterproof, seasoning.
Background technology
At present, there are a lot of defectives in the coal in gasified industry type of domestic existing production, and is non-watertight as moulded coal, needs oven dry, the cost height, cold strength is low, and gasification result is bad, and evil mind is arranged, and reductibility is poor, vaporization rate is low, the oxygen content height, and carbon monoxide yields poorly, and caloric power of gas is low.Be not suitable for mass production, can't transport for long-distance.Need add packing and also have the high problem of cost, binding agent price height is subjected to resource limit to human body, environment all is harmful to.
Summary of the invention
In order to overcome the deficiency that above-mentioned moulded coal exists, the invention provides a kind of pressure gasified, water-repellent, drying free agent for bonding coal in gasified industry type that is applicable to large-scale gas furnace gas making.The moulded coal cold strength height that this binding agent is produced, Heat stability is good, factor of created gase height, economize on coal, technology is simple.It is the binding agent that is applicable to various coals.
The technical solution adopted for the present invention to solve the technical problems is: this binding agent utilizes Sorel cement 50%, wilkinite 15%, steel melting furnace waste slag 20%, graphite tailing 10%, tertiary sodium phosphate 5% to mix, after stirring, present the inorganic binding agent of powdery, stir in the middle of then it being joined feed coal, add water aftershaping coal and need not oven dry, can use.
The invention has the beneficial effects as follows:
1, wider than other binding agent resource, price is low.Nuisanceless,, technology is simple, need not dry.
2, do not change the combustionproperty of moulded coal, do not reduce thermal value.
3, hot strength height, good mechanical property.
4, good waterproof performance, water logging is three months in molten device, and the not broken water that do not split does not mix, and cold strength does not reduce.
5, Well-recovered, burning is tree peony flowers type, and gasification performance is good, and lime-ash carbon residue amount is low.
6, captured sulfur result is higher 3 times than other binding agent, and dust-exhausting quantity moulded coal per ton reduces 3 kilograms than other coal.
7, low 0.5-1 Lin Geman that reaches of jet-black degree.The flue gas dust-exhausting quantity is 84.8 milligrams every cubic metre.Be the environmental protection optimum fuel, social benefit is good.
Embodiment
The present invention is further described below in conjunction with embodiment
The flour that utilizes cheap Sorel cement and wilkinite, steel-making waste slag, graphite tailing, tertiary sodium phosphate to mix, their ratio is respectively, Sorel cement 50%, wilkinite 15%, steel-making waste slag 20%, graphite tailing 10%, tertiary sodium phosphate 5%, by the disk feeder quantitative ingredient, through superfine grinding, present the inorganic binding agent of powdery after the stirring, stir in the middle of then it being joined feed coal, add water aftershaping coal and need not oven dry, can use.
Claims (1)
1, a kind of powder binder of pressure gasified, water-repellent, drying free coal in gasified industry type, the processing that it is characterized in that this binding agent is that (by weight) Sorel cement 50%, wilkinite 15%, steel melting furnace waste slag 20%, graphite tailing 10%, tertiary sodium phosphate 5% are mixed, and presents the inorganic binding agent of powdery after stirring.
