Abstract
An oil-base coal slurry fuel is prepared from oil (10-40 wt.%), water (10-30), coal (40-60) and emulsifier and disperser (0.5-3) through breaking raw coal, wet grinding, superfine processing, filtering, adding it to oil-water emulsifying system, and high-speed stirring. The slurry fuel has good fluidity and stability, can save a large amount of fuel oil, has low ash content and high heat value of 5000-8000 kcal/kg, and can be widely used for replacing combustion oil for low-load operation of industrial boilers, industrial kilns and power plants.
Description
The present invention relates to oil-base coal fluid fuel and preparation technology, i.e. oil base ternary fuel slurry and the preparation technology who forms with oil, water, coal.
Two big hot issue-energy and environmental protection of current society, with regard to China, quite be difficult to change in period based on the energy general layout of coal, the future source of energy environmental problem is outstanding, developing clean coal technology is the selection of reality, and the coal slurry technology is an important content in the clean coal technology.In in the past more than 20 year, what coal oil mixture and coal water slurry fuel were used for oil-firing boiler has caused people's common concern for oil fuel, because they are a kind of coal-based generation flow of oil fuel, can be used on Industrial Boiler, station boiler, industrial furnace cellar for storing things previous generation's oil or for gas firing, and also play a part certain reducing environmental pollution.But because the coal oil mixture fuel-economizing is few, and viscosity height, price are expensive, thereby replaced very soon by coal water slurry, coal water slurry has very big superiority in fuel-economizing aspect transporting safely, solved large-scale production process at home and abroad, but coal water slurry is being had relatively high expectations aspect the selection of slurrying coal, its burning-point is higher, calorific value is lower, be only applicable to the high bituminous coal of high volatile, coal water slurry is also higher to the requirement of pipeline and nozzle in addition, the improvement expenses costliness.
The purpose of this invention is to provide that a kind of burning-point is lower, calorific value is higher, fuel-economizing, improvement expenses is lower, is used to replace the oil-base coal fluid fuel and the preparation technology of Industrial Boiler, Industrial Stoves and power station underrun.
Oil-base coal fluid fuel of the present invention, but with fuel oil, water, coal add emulsifying agent in proportion, dispersion agent is uniformly mixed into slurry, its content is respectively: oil accounts for 10~40%, and water accounts for 10~30%, coal accounts for 40%~60%, and emulsifying agent and dispersion agent respectively account for 0.5~3% (weight percent).Used emulsifying agent adopts Span-85, Span80 series nonionic surface active agent, and dispersion agent is Sulfonates, alkylphenol polyoxyethylene class and oleic-acid, and dispersion agent is the mixture of nonionic surface active agent and aniorfic surfactant; But fuel oil can be gasoline, diesel oil, heavy oil, residual oil or crude oil.
The preparation technology of oil-base coal fluid fuel of the present invention: with the raw coal fragmentation, through wet-milling super-fine processing, filtration, join then (that is: oil and dispersion agent stir, and add the system of emulsifying agent and water stirring and emulsifying again) in the oil-water emulsion system, through high-speed stirring emulsification pulping.
Oil-base coal fluid fuel of the present invention and preparation technology, the oil base ternary fuel slurry and the preparation technology that adopt oil, water, coal to form, this fuel slurry flowability and good stability can be saved a large amount of oil fuel, and its point of ignition is lower than coal water slurry; This fuel slurry fine size, ash content is low, thereby the unit volume calorific value is higher: 5000~8000kcal/kg can be widely used in the burning oil when replacing Industrial Boiler, Industrial Stoves and power station underrun, its economic benefit and obvious social benefit have practicality widely.
Below in conjunction with embodiment the present invention is further described:
Oil-base coal fluid fuel of the present invention, but by fuel oil, water, coal add emulsifying agent in proportion, dispersion agent is uniformly mixed into slurry, wherein emulsifying agent adopts Span-85, Span80 series nonionic surface active agent, and dispersion agent is Sulfonates, alkylphenol polyoxyethylene class and oleic-acid.Dispersion agent is the mixture of nonionic surface active agent and aniorfic surfactant, but fuel oil can be gasoline, diesel oil, heavy oil, residual oil or crude oil.
Its preparation technology:,, join then (that is: oil and dispersion agent stir, and add the system of emulsifying agent and water stirring and emulsifying again) in the oil-water emulsion system, through high-speed stirring emulsification pulping through wet-milling super-fine processing, filtration with the raw coal fragmentation.
Embodiment 1: with oil 300 grams (30%), add emulsifying agent 16.1 grams, add water 180 grams (18%), high-speed stirring emulsification adds dispersion agent 3.9 grams (emulsifying agent and dispersant dosage 2%) again, coal dust after the super-fine processing (granularity<20 μ m) 500g (50%), fully mix, high-speed stirring emulsification pulping is 10 minutes again, promptly makes stable oil-base coal fluid fuel, when shear velocity was 100 seconds, viscosity was 960mPa..S.
Embodiment 2: with oil 200 grams (20%), add emulsifying agent 8 grams, add water 290 grams (29%), high-speed stirring emulsification adds dispersion agent 2 grams (emulsifying agent and dispersant dosage 1%) again, coal dust after the super-fine processing (granularity<20 μ m) 500g (50%), fully mix, high-speed stirring emulsification pulping is 10 minutes again, promptly makes stable oil-base coal fluid fuel, when shear velocity was 100 seconds, viscosity was 780mPa..S.
Embodiment 3: be heated to 70-80 ℃ with oil 350 grams (35%), add emulsifying agent 17 grams, add water 130 grams (13%), high-speed stirring is even, adds dispersion agent 3 grams (emulsifying agent and dispersant dosage 2%) again, adding is through coal dust (granularity<20 μ m) 500 grams (50%) of super-fine processing, fully mix, high-speed stirring emulsification pulping is 8 minutes again, promptly makes oil-base coal fluid fuel, when shear velocity was 100 seconds, viscosity was 1000mPa..S.
