Description
Technical field
Patent of the present invention is related to the fields such as environmental conservation, garbage disposal and recovery and reuse of waste and in particular to pulverizing knot screen to a kind of biomass.
Background technology
The energy and environmental problem are the topmost problems that the 21 century mankind are faced.
China's natural gas yield is average annual nearly ten years increases by 13%, and Natural Gas Consumption Using increases by 16% every year.The natural gas of China in 2010 proportion in energy resource structure is 4.4%, and accounting is 5.4% within 2012, and accounting is 5.9% within 2013.Annual natural gas Apparent con- sumption is 1676 billion cubic meters within 2013, and natural gas consumption exceedes Iran, becomes global the third-largest natural gas consumption state, and external dependence degree reaches 31.6%（53000000000 cubes）.
" bio-natural gas " refer to the biological flue gas based on methane content being transformed into various organic biomass by anaerobic fermentation.Exploitation bio-natural gas are significant to alleviating gas supplying pressure, cause and extensively pay attention to both at home and abroad.
The stock number of 5 traditional class bio-natural gas resources of China is huge：（1）Changing food waste, year can collect 30,000,000 tons,；（2）Domestic sewage factory mud, year 40000000 tons of yield；（3）Biomass in house refuse, year can 1.2 hundred million tons of collecting amount；（4）Feces of livestock and poultry, year can be 2,200,000,000 tons by collecting amount；（5）Agricultural crop straw and about 100,000,000 tons of residual processing thing year amount usable.Calculate by the average methane content 60% and bio-natural gas methane content 97% of biogas, can year 129500000000 cubes of biogas of output and 80,000,000,000 cubic natural gas.
Changing food waste and house refuse, because the debris that many is not suitable for fermenting also are contained in the inside, need biomass are carried out in pretreatment, the stone of removal the inside, sandstone, plastics etc..
House refuse and changing food waste, through pretreatment, still suffer from that screening efficiency is low, screening is artificial measures big, the low key issue of mechanization degree at present.Pretreatment efficiency is low, not only affect the economic and technical norms of engineering project, more importantly have a strong impact on follow-up anaerobic fermentation process because the sandstone inside biomass slurry can wear and tear pipeline, blocking valve, anaerobic fermentation tank bottom deposit reduce tank body dischargeable capacity；The plastics of the inside and fibre debris not only easily block pipeline, also can swim in anaerobic fermentation tank liquid surface, form a scab when serious.These impurity that the inside is contained also directly affect quality and the selling price of biogas residue organic fertilizer.
Therefore, research and develop biomass pre-processing device, provide for anaerobic fermentation system the serosity of high-quality extremely important.At present, pretreating process and pre-processing device progressively molding in its effectiveness, but yet suffer from several difficult points, such as：Desanding efficiency low or cannot desanding it is impossible to homogenate to anaerobic fermentation requirement etc..And, current biomass pulverize impurity removing equipment seldom, majority be provided purely for pulverizing or single carry out remove impurity, so not only high cost, process put into big, and, often traditional disintegrating apparatus cannot meet the broken requirement of biomass.
In order to be able to organically combine and production department's biological flue gas the anaerobic ferment process of the pretreating process of leading portion and rear end, a kind of tentatively pretreated biomass are pulverized and the equipment of remove impurity is just particularly important.
Content of the invention
The present invention is mainly aiming at above-mentioned the deficiencies in the prior art and demand, a kind of novel device being applied to Chinese rubbish present situation, efficient pulverizing separating biomass is provided, solve the problems, such as the advanced treating of the biomass that rubbish tentatively screens out, with the abundant feed needs adapting to anaerobic ferment process.
The feature of this equipment is, using special crushing cutter group and paddle blade structure, biomass effectively can be pulverized in shattering process, simultaneously little to the degree of fragmentation of plastics, fabric, the biomass pulverized are under the centrifugal action that high-speed rotary main shaft produces, separated by screen drum, the little material of the degree of fragmentation such as plastics, fabric passes through guide helical feed to debris discharging opening, is not repeatedly pulverized in the presence of clear material spiral by the biomass of fully pulverizing simultaneously.The special construction of this equipment and design are it is ensured that good to biomass crushes and impurity-eliminating effect.And this equipment profile is exquisite, floor space is little, treatment effeciency is high, treating capacity is big, broken thorough, for ease of maintenaince.
