Description
Technical field
The present invention relates to a kind of vibration nixing sieve that different materials is mixed, simultaneously, the invention still further relates to the hybrid system of using this vibration nixing sieve.
Background technology
In the energy resource structure of China, the abundantest with coal resources, in fossil fuel constituted, coal resources accounted for 95.4 ﹪, and oil accounts for 3.3 ﹪, and natural gas accounts for 1.3 ﹪.About 2/3 of the annual raw coal output of China is used for burning, and wherein, Industrial Boiler uses 1/3; Station boiler uses 1/3, and Industrial Boiler need use the high fat coal of volatile matter, when the coal that uses than low volatile; When burning like meager coal, operating mode is poor, and boiler output and boiler hot are renderd a service all lower; Hinder effective utilization of coal, caused waste.
In addition, in the burning of coal process, also have a large amount of environmental problems, it also is that the quantity that comes into operation is also very low in popularization that existing Industrial Boiler is used the sulfur in smoke desulphurization plant.The tradition desulphurization plant biases toward passively to be removed the sulfur dioxide in the smoke evacuation, owing to increase operating cost after these desulphurization plant inputs, troublesome poeration, secondary product harmless treatment after the desulfurization is complicated, reclaims difficulty, often causes secondary pollution.For example: exploitation wet flue gas desulfurization equipment on the basis of granite with water film (or spray) deduster; Like simple water washing mode desulfurization degree about 18 ﹪; Recycle washings, it is acid that water becomes gradually, serious to equipment corrosions such as circulating pump pipelines; Recycle repeatedly and also want discharge section acid waste water, cause secondary pollution.Add the bases chemical products and can improve desulfuration efficiency, but the secondary product (sulfate etc.) that produces in such water after the desulfurization still can enter city, rural waters, further contaminated environment.Therefore, even there is minority unit's boiler that desulphurization plant is arranged, also do not put into operation at ordinary times, just buy the desulfurizing agent power of coming into operation when just checking in environment monitoring department, like this, the real target of protection environment is difficult to fulfill.Industrial boilers in China is added up according to the general survey of industry in 1998: about 50.12 ten thousand of use amount; Will burn 1/3rd of annual output of coal every year; Because contain sulphur in the coal, sulphur is converted into sulfur dioxide in combustion process, get into atmosphere through fume emission; Contaminated environment, the sulfur dioxide in the atmosphere combine to form acid rain with rainwater in rainfall.Acid rain brings very big harm to crops; The whole nation is annual because of economic loss that causes of acid rain just reaches 1,100 hundred million yuan according to statistics, and coal-burned industrial boiler is to the improvement of SO 2 from fume, does not have technologically at present, the input of equipment is also very low; It is still higher to add to the desulfurization operation expense; Therefore, the desulfurization present situation and the contradiction between the environmental aspect of flue gas are very outstanding, and sulfur dioxide harm is administered very urgent.
On the other hand, constantly occur peasant's crop straw burning at present, so promptly wasted bioenergy, atmosphere pollution again, even can bring disaster hidden-trouble, large tracts of land is burned dense smoke that agricultural crop straw produces even the takeoff and landing that have influence on the airport.On the other hand along with the improving constantly of China's living standards of the people, the increasing demand of coal, electric power, oil, natural gas equal energy source is increased, coal equal energy source price is risen steadily, imbalance between supply and demand displays day by day.And the simultaneously branch of the pruning of a large amount of agricultural wastes forests and fruit industry in rural area, bark etc.; Agricultural crop straw such as maize straw bottom, corncob, peanut shell is abandoned promptly influences rural environment; And straw-returning needs certain condition and a certain amount of, and the amount of surpassing just goes wrong; The rotten value of stalk requires soil moisture >=20 ﹪ will increase amount of nitrogenous fertilizer needs long time, it before not forming rotten value matter, to different types of also field following season of quantity crops sowing and the bigger influence of field management generation.If can stalk be processed into coal additive, in Industrial Boiler stove internal combustion, it can not produce black smoke, and the smoke evacuation dark brown can reach 0-1 grade of lingemann value.Therefore we can say that mixed preparing coal of the present invention is again a kind of than clean energy resource.Preparation is the reproducible energy still, and it is mixed the mixed preparing coal, can favourable greatly burning of coal operating mode; Lower to volatile matter by it, the higher meager coal of burning-point burns very favourable, can play and improve combustion conditions; Improve coal utilizaton rate, increase boiler heat load, improve the burning of coal degree, play and economize on coal; Improve boiler thermal output, alleviate double benefit atmosphere pollution.The present invention can make a large amount of agricultural wastes crop straw refuses become resource as a kind of novel preparation energy, can be Industrial Boiler again and utilize volatile matter low, and low meager coal, the low volatile ature of coal of sulfur content can rationally be utilized, and finds new approach.Make the utilization of resources of agricultural wastes crop straw refuse, practice thrift coal, improve the combination of boiler thermal output and protection environment.How mix discarded object agricultural crop straw and coal are organic, making the good effect of performance that mixes in combustion process of discarded object agricultural crop straw and coal be one has problem to be solved.
