Description
Technical field
The present invention relates to a kind of vibration nixing sieve mixed by different materials, meanwhile, the invention still further relates to the hybrid system using this vibration nixing sieve.
Background technology
In the energy resource structure of China, the abundantest with coal resources, in fossil fuel is formed, coal resources account for 95.4 ﹪, and oil accounts for 3.3 ﹪, and natural gas accounts for 1.3 ﹪.The annual raw coal output of China about 2/3 for burning, wherein, Industrial Boiler uses 1/3, boilers of power plants 1/3, and Industrial Boiler need use the high fat coal of volatile matter, when using the coal compared with low volatile, during as Lean coal firing, operating mode is poor, boiler output and boiler hot effect all lower, hinder effective utilization of coal, cause waste.
In addition, in burning of coal process, also there is a large amount of environmental problem, existing Industrial Boiler is to the sulfur dioxide desulfurization equipment application in flue gas also just in popularization, and the quantity come into operation is also very low.Tradition desulphurization plant biases toward passively to be removed the sulfur dioxide in smoke evacuation, due to these desulphurization plants drop into after increase operating cost, troublesome poeration, secondary product harmless treatment after desulfurization is complicated, reclaims difficulty, often causes secondary pollution.Such as: on the basis of granite with water film (or spray) deduster, develop wet flue gas desulfurization equipment, as simple water washing washs mode desulfurization degree at about 18 ﹪, washings are recycled, water becomes acid gradually, serious to equipment corrosions such as circulating pump pipelines, iterative cycles uses and also wants discharge section acid waste water, causes secondary pollution.Add bases chemical products and can improve desulfuration efficiency, but the secondary product (sulfate etc.) after producing desulfurization in such water still can enter city, rural waters, further contaminated environment.Therefore, even if there is minority unit boiler to have desulphurization plant, also do not put into operation at ordinary times, just just buy the desulfurizing agent power of coming into operation when environment monitoring department checks, like this, the real target of protection of the environment is difficult to fulfill.Industrial boilers in China is added up according to the general survey of industry in 1998: use amount about 50.12 ten thousand, / 3rd of an annual output of coal to be burnt every year, owing to containing sulphur in coal, sulphur is converted into sulfur dioxide in combustion, air is entered through fume emission, contaminated environment, the sulfur dioxide in air is combined with rainwater and forms acid rain in rainfall.Acid rain brings high risks to crops, the whole nation is every year because acid rain economic loss caused just reaches 1,100 hundred million yuan according to statistics, coal-burned industrial boiler is to the improvement of SO 2 from fume, current nothing technologically, the input of equipment is also very low, add to desulfurization operation expense still higher, therefore, the contradiction between the desulfurization present situation of flue gas and environmental aspect is very outstanding, and sulfur dioxide harm is administered very urgent.
On the other hand, constantly occur peasant's crop straw burning at present, so namely waste bioenergy, again atmosphere pollution, even can bring disaster hidden-trouble, the dense smoke that large area Burning Straws produces even has influence on the takeoff and landing on airport.Improving constantly along with our people's living standard on the other hand, day by day increase the demand of coal, electric power, oil, natural gas equal energy source, coal equal energy source price is risen steadily, and imbalance between supply and demand displays day by day.And the branch, bark etc. of the pruning of the agricultural wastes forests and fruit industry that rural area is a large amount of simultaneously, agricultural crop straw as maize straw bottom, corncob, peanut shell is abandoned namely affects rural environment, and straw-returning needs certain condition and a certain amount of, and the amount of exceeding just goes wrong; The rotten value of stalk requires that soil moisture >=20 ﹪ will increase amount of nitrogenous fertilizer and need longer time, and it is not before forming rotten value matter, on different types of also field quantity lower season crops sowing and the larger impact of field management generation.If stalk can be processed into coal additive, in Industrial Boiler stove combustion, it can not produce black smoke, and smoke evacuation dark brown can reach lingemann value 0-1 grade.Therefore mixed preparing coal of the present invention is again one comparatively clean energy resource.Preparation or the reproducible energy, it is mixed mixed preparing coal, can greatly favourable burning of coal operating mode, lower to volatile matter by it, the Lean coal firing that burning-point is higher is very favourable, can play and improve combustion conditions, improve coal utilizaton rate, increase boiler heat load, improve burning of coal degree, play and economize on coal, improve boiler thermal output, alleviate the double benefit to atmosphere pollution.The present invention, as the novel preparation energy of one, can make a large amount of agricultural wastes crop straw refuse become resource, can be again Industrial Boiler and utilize volatile matter low, and meager coal, low volatile ature of coal that sulfur content is low, can Appropriate application, finds new approach.Make the utilization of resources of agricultural wastes crop straw refuse, save coal, improve the combination of boiler thermal output and protection of the environment.How to mix organic to discarded object agricultural crop straw and coal, make mixing of discarded object agricultural crop straw and coal play good effect in combustion and be one and have problem to be solved.
