Description
Technical field
The present invention relates to the preparation method of organic particle fuel, particularly relate to the method that high carbonaceous black shale mixed biologic material prepares organic particle fuel.
Background technology
Along with world's Nonrenewable energy resources are petered out, people start to find new surrogate, and from shale, obtain fuel such as shale gas etc. has become the recent tendency of current world energy sources industry.As OSAT LLC's application, publication number is disclose name in the patent documentation of CN101506331A to be called that releasing organics is to produce the method for liquid shale fuel from shale and similar substance, the method by by vartex motion, wave motion, acoustic streaming turbulent flow, or in their combined treatment liquid medium shale oil powder and from shale oil and similar solid matter the method for releasing organics matter.
And with regard to domestic, the development and utilization shale energy also gradually by people cognition, its medium high carbon matter black shale is exactly a kind of mineral species of worth development and utilization.Black shale refers to the shale being rich in organic matter and DISPERSE YELLOW iron ore, spathic iron ore and aobvious black, little fossil, the very thin bedding of normal tool, outward carbonaceous shale seemingly, but does not contaminate hand.When thickness is large, good Source Beds can be become.Generally the reducing environment formation in the lake under warm humid climate, marsh.The metalliferous deposits such as uranium, copper, molybdenum, vanadium, nickel are found that there is in black shale.Black shale can as the instruction stratum of oil.
The high carbonaceous black shale in south China area is widely distributed, and organic content is high, aboundresources, but because its fuel value is not high enough, ash content is many, is developed preferably for a long time.Meanwhile, China's agricultural-forestry biomass energy raw material is very abundant, is only utilized to lesser extent, more as agricultural and forestry production waste or directly burn, and brings certain environmental problem.By adding biological energy raw material toward high carbonaceous black shale, ash oontent in carbonaceous black shale can be reduced, improve its fuel value, becoming available Energy resources.But, there is no the method effectively utilizing high carbonaceous black shale as fuel in prior art.
Summary of the invention
The object of the invention is to overcome prior art defect; a kind of high carbonaceous black shale mixed biologic material is provided to prepare the method for organic particle fuel; the method utilizes high carbonaceous black shale and biomass material to be mixed with fuel; high carbonaceous black shale and agricultural-forestry biomass raw material are made full use of, and this can not only increase economic efficiency and can also preserve the ecological environment.Not only cost is low for the organic particle fuel of preparation, and superior performance, partly can replace traditional fuel.
The present invention is achieved in that the present invention is the method that high carbonaceous black shale mixed biologic material prepares organic particle fuel, calculate by mass percentage, organic carbon content in described high carbonaceous black shale is 10% ~ 20%, sulphur content is no more than 1.0%, nitrogen content is less than 0.5%, ash oontent is less than 12%, volatile content is 20 ~ 25%, method of the present invention with high carbonaceous black shale and biological material for raw material, be high carbonaceous black shale by mass fraction proportioning raw materials: biological material=1:1 ~ 1:3, described biological material is a kind of or the biomass combustiblematerials of more than two kinds composition mixing.Specifically, biological material refers to conventional wooden fuel and the animal excrement etc. such as the agricultural crop straw such as corn, wheat, paddy rice, wood chip, reed, branch.Biological material adds more, as high carbonaceous black shale: when biological material=1:3, prepare solid particle fuel to have good burning performance, but black shale utilization ratio will reduce, if reduce black shale addition further, then the utilization ratio of black shale just seems insignificant, thus causes solving technical problem of the present invention.Biological material adds not enough, the solid particle fuel fuel value prepared then is difficult to reach requirement, as high carbonaceous black shale: when biological material=1:0.8, the solid particle fuel fuel value prepared just cannot meet the demands certainly, also can cause solving technical problem of the present invention.
The concrete steps that high carbonaceous black shale mixed biologic material of the present invention prepares the method for organic particle fuel are: high carbonaceous black shale and biological material are pulverized respectively, this pulverizing first high carbonaceous black shale is milled to 90 ~ 110 orders, biomass material is crushed to powder particle size simultaneously and is less than 5mm; Then prepared using sieve apparatus after pulverizing is screened, extract relatively large thing and foreign material; Dry the raw material after screening, high carbonaceous black shale raw material drying machine working temperature is 70 ~ 80 DEG C, and biomass material drying machine working temperature is about 80 DEG C; By proportioning raw materials by high carbonaceous black shale and biological material Homogeneous phase mixing; Then utilize particle processing machinery to carry out pressurizeing, density, shaping; Finally shaping rear product is delivered to cooling apparatus to carry out cooling and can obtain granular fuel finished product.
Preparing organic particle fuel finished product is cylindrical shape solid molding fuel, and its diameter is 6 ~ 8mm, and length is 3 ~ 4 times of its diameter, thermal value is 3000kcal/kg ~ 4000kcal/kg, sulphur content is no more than 0.8%, and nitrogen content is less than 0.5%, and ash oontent is less than 10%.
Technique effect of the present invention: the preparation cost of the organic particle fuel that the present invention utilizes high carbonaceous black shale and biomass material to prepare is cheap, energy consumption is low; Obtain the alternative parts of traditional fuel of organic particle fuel; High carbonaceous black shale and biomass material abundance, production technique is simple, and product has higher environment and'economy benefit, has great significance to the recycling of high carbonaceous black shale and agricultural-forestry biomass raw material, ecological environmental protection.
Society, environmental benefit:
1, the destruction of environment being caused because adopting traditional fuel can be reduced;
2, the recycling of high carbonaceous black shale and agricultural-forestry biomass raw material can be promoted, increase agricultural and forestry production person's income;
3, fuel cost and the dependence to traditional fuel can be reduced.
Along with Chinese national economy sustained and rapid development, the hurried increase of energy consumption.China's Energy resources total amount is abundanter, but per capita energy's resource owning amount is lower, and coal and waterpower resourses per capita owning amount are equivalent to 50% of world average level, and oil, the Sweet natural gas per-capita quantity of the resources are only about 1/15 of world average level.30% of cultivated land resource not enough world per capita share, constrains the exploitation of biomass energy.The trend of current energy source development: scientific development substitute energy, Optimization of Energy Structure, realizes providing multiple forms of energy to complement each other, and ensures the stable supply of the energy; Adhere in development, realizing protection, promoting development in protection, realize Sustainable development.And high carbonaceous black shale mixed biologic material prepares the birth of organic particle fuel technology; comply with this trend just; both effectively supplemented for power supply provides, and facilitated again recycling and ecological environmental protection, can remarkable economy, environment, social benefit be produced.
