Abstract
The invention relates a sand coal compound fuel and the production process, which is that: one or more in soft coal, simmer coal or anthracite are grinded into coal dust with a diameter less than 0.2 mm by a coal pulverizer. One or more in mountain sand, riverbed sand, scree, sandstone, conglomerate, basalt, basalt and siliceous shale which have a major component of silicon dioxide are processed into sand powder with a diameter less than 0.2 mm by a Raymond mill, a T-mill or other ore mill. The coal dust and the sand powder are mixed by a weight ratio of 1:3; a coal slurry and the sand powder or quartz sand are mixed by a weight ratio of 1:2, and then mixed with water to be mud, finally is shoveled into blocks to dry. The mud also can be processed into coal briquette, honeycomb briquette or coal brick by a briquette machine, a coal briquette machine or a brick machine for building.
Description
The present invention relates to a kind of New-type fuel, the particularly husky a kind of fuel that combines with coal.Nearly two over 100 years, and coal becomes the human topmost energy, is widely applied in the productive life, is called as " grain of industry " as the most important energy, and still, coal has also brought unprecedented disaster to the mankind when promoting human industrial development---
The first, directly right coal can produce a large amount of carbonic acid gas, causes Greenhouse effect, causes global warming, and then causes eco-catastrophe.The expert of foreign country calculates climate warming and can cause 5.9 trillion dollars loss to the mankind, and the Asia has 1,000,000,000 people's lacks of water, and the germ that hundreds of millions of people can be multiplied devitalizes.
The second, directly coal-fired meeting produces multiple obnoxious flavoures such as carbonic acid gas, carbon monoxide, sulfurous gas, meeting polluted air, infringement HUMAN HEALTH.
The 3rd, when directly coal-fired, coal can not fully burn, and can produce a large amount of lime-ash, has not only caused the waste of coal, but also has caused environmental problem.
The 4th, the annual coal resources that all consume flood tide in the whole world, it is exhausted to cause coal resources to be about to.
In order to address these problems, many in the world scientists seeking a kind of new energy to solve the difficult problem of climate warming, solve environmental problem and energy problem." Reference News " once reported, in the laboratory, the burn experiment of sand of a Japanese scientist, after this scientist allowed sand burn in nitrogen, the energy that calculates one kilogram of silicon release of burning will be far longer than one kilogram of energy that coal discharged of burning, and free from environmental pollution.Also having many on the internet is the report of future source of energy about sand, if any one piece of article " human following oil-sand ".The Chinese Central Television (CCTV) also has sand can become the report of human future source of energy.
(4) Fa Ming content:
The present invention relates to the fuel composition that Sha Yumei (bituminous coal, stewing charcoal hard coal) combines by a certain percentage, sand accounts for many parts in the said composition, and coal has accounted for small part.To burn sand serves as that main burning coal is auxilliary.Sand composition in this fuel itself can not produce deleterious greenhouse gases such as carbonic acid gas, carbon monoxide, sulfurous gas when burning.The main component of sand is a silicon-dioxide, and silicon can generate " lime-ash " such as carborundum, silicon hydride, silicon sulfide, silicon nitride, silicon fluorides with reactions such as carbon in the coal, hydrogen, nitrogen, fluorine when burning with coal, should.These resultant of reaction finally also can be reduced into harmless sand, do not pollute the environment.Coal in this fuel has been processed to the burning of powder thereby energy fullest, can not cause the waste to coal.This fuel has become sand can give birth to the energy by incendiary; the carbonic acid gas that this fuel produces is less than the simple combustion carbonic acid gas that the matchmaker produced far away; can reduce carbonic acid gas isothermal chamber gas purging to greatest extent; will effectively contain or mitigation of global climate warms, alleviating energy crisis and ecotope crisis.
According to the present invention, comprise with silicon-dioxide in the above-mentioned fuel composition being the husky component (A) of main component and being the coal component (B) of main component with carbon.Component (A) is:
(A) (1) is processed into particle diameter to the sand on riverbed sand or the Da Sha mountain less than 0.2 millimeter husky powder with grinding machinery (as Raymond mill, T type mill), if above-mentioned sand is better with effect after sieving and washing husky equipment and removing the purity of impurity raising silicon-dioxide such as dust in the sand; Being that any or several rocks in the cobble, sandstone, conglomerate, basalt, volcanics, siliceous shale of main component are pulverized to grind with the ore disintegrating apparatus and are machined into particle diameter less than 0.2 millimeter husky powder with silicon-dioxide.
(A) (2) natural quartz sand.
Component (B) is:
(1) bituminous coal is worn into the coal dust of particle diameter≤0.2 millimeter with coal-grinding machinery.
(2) bituminous coal is worn into the coal dust of particle diameter≤0.2 millimeter with coal-grinding machinery.
(3) bituminous coal is worn into the coal dust of particle diameter≤0.2 millimeter with coal-grinding machinery.
(4) coal slime
The consumption of component (A) account for component (A) and component (B) gross weight-
When using (A) (1) with (B) (1), preferably 75%
When using (A) (1) with (B) (2), preferably 70～77.5%
When using (A) (1) with (B) (3), preferably 70～80%
When using (A) (1) with (B) (4), preferably 66%
When using (A) (2) with (B) (4), preferably 66%
Said components is mixed back water and become mud according to the above ratio, produce with spade and piece dry or pile up and just dry and to have used.In order better to use this fuel, make honeycomb briquette, coal briquette, briquet with briquetting press, honey-comb briquet, clay-brickmaking machine for building, dicer and used with regard to more convenient.
I am that usefulness and original manual method thereof are developed these husky powder and coal dust because there is not the pulverising mill control equipment.In test, directly add 1/3rd husky powder in the raw coal, coal still can trouble-free burning, three/ for the moment just needs to wear into coal when husky powder surpasses≤0.2 millimeter coal dust.When husky powder account for sand coal composite fuel 30～75% the time, effect of combustion is all very good.
Do not have absolute in the world, if the dioxide-containing silica in the sand is lower, can suitably reduce the ratio of sand, if it is the dioxide-containing silica in the sand than higher, can suitably increase the ratio of sand, same, if the carbon content of coal is lower, the ratio of coal can be suitably increased,, the ratio of coal can be suitably reduced if the carbon content of coal is higher.Dioxide-containing silica reaches the percent 90-99. ratio that Sha Fenyu simmers charcoal when above and can reach 1 to 4 in the sand, and husky powder can reach 1 to 5 with anthracitic ratio.
In test, the sandy soil on this human coal dust and the outdoor any vacant lot are by 3 to 1 mixed, Jia Shui with become mud, shovel and piece dry, just can burn.
In test, the maximum ratio of husky coal once reached 1 to 8, and still, husky effect of combustion is just bad later on above 80%.
I usually am used for cooking, heat up water and warm oneself with sand coal composite fuel in test.
It is as follows that this invention and background technology are compared the beneficial effect that is had:
Traditional coal fuel can produce a large amount of deleterious " greenhouse gases " such as carbonic acid gas in when burning, harm humans health not only, and cause global temperature to rise with surprising rapidity, cause environmental disaster.The ratio of coal only accounts for sub-fraction in the sand fuel, and the ratio of sand has accounted for exhausted big part, and coal not only incendiary is abundant, and combustion products all can be reduced into sand, can reduce discharge of harmful gases such as carbonic acid gas to greatest extent.
