Description
Technical field
The utility model relates to a kind of vibration nixing sieve that different materials is mixed, and simultaneously, the utility model also 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 consisted of, 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, wherein, Industrial Boiler uses 1/3, and boilers of power plants 1/3, Industrial Boiler need use the high fat coal of volatile matter, when the coal that uses than low volatile, during such as Lean coal firing, 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, also have a large amount of environmental problems in the burning of coal process, it also is that the quantity that comes into operation is also very low in popularization that existing Industrial Boiler is used the sulfur dioxide desulfurization equipment in the flue gas.The tradition desulphurization plant biases toward passively to be removed the sulfur dioxide in the smoke evacuation, because these desulphurization plants increase operating cost after dropping into, and troublesome poeration, the secondary product harmless treatment after the desulfurization is complicated, reclaims difficulty, often causes secondary pollution.For example: at the basis exploitation wet flue gas desulfurization equipment of granite with water film (or spray) deduster, such as simple water washing mode desulfurization degree about 18 ﹪, washings are recycled, it is acid that water becomes 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 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 of the 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, owing to contain sulphur in the coal, sulphur is converted into sulfur dioxide in combustion process, enter atmosphere through fume emission, contaminated environment, the sulfur dioxide in the atmosphere are combined with rainwater in rainfall and are formed acid rain.Acid rain brings very big harm to crops, the whole nation just reaches 1,100 hundred million yuan because of economic loss that causes of acid rain every year according to statistics, coal-burned industrial boiler is to the improvement of SO 2 from fume, at present without technologically, the input of equipment is also very low, it is still higher to add to the desulfurization operation expense, therefore, 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, peasant's crop straw burning constantly occurs at present, so namely wasted bioenergy, atmosphere pollution again, even can bring disaster hidden-trouble, the dense smoke that the large tracts of land Burning Straws produces even have influence on the takeoff and landing on airport.On the other hand along with the improving constantly of China's living standards of the people, the demand of coal, electric power, oil, natural gas equal energy source is increased day by day, 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 namely affects 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, on different types of also field lower season of quantity crops sowing and field management produce larger impact.If stalk can 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 mixed preparing coal of the present invention is again a kind of than clean energy resource.Preparation or the reproducible energy, it is mixed the 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 the burning of coal degree, play and economize on coal, improve boiler thermal output, alleviate the double benefit to 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 again Industrial Boiler 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, save coal, improve the combination of boiler thermal output and protection of the environment.How mix discarded object agricultural crop straw and coal are organic so that discarded object agricultural crop straw and coal mix that the good effect of performance is a problems to be solved in combustion process.
