垃圾分选系统

一、 垃圾分选系统垃圾分选，历来是垃圾处理技术的瓶颈，不管是焚烧、填埋处理工艺，还是综合处理工艺，很多失败案例都是因为垃圾分选不彻底， 导致下工序无法处理而使整条生产线都不能正常运行。城市生活垃圾“ LJ”五化处理技术 - 垃圾分选系统，是该技术的核心， 该系统通过垃圾均匀给料、 大件垃圾自动分选系统、 大件垃圾破碎系统、袋装垃圾自动破袋、 大块有机物自动破碎系统、 全封闭机械化风选系统、塑料水选系统、有机物高温高压水解水热氧化“热选”系统等工艺处理后，可将城市生活垃圾分选为： 1) 无机物类； 2)砂土类； 3) 有机物类； 4)不可回收可燃物类 （若辅以简单人工分选， 还可以分出硬质塑料、 橡胶等）； 5)薄膜塑料类；6)铁磁物类 .以上垃圾，分选纯度均可达到 85%以上，薄膜塑料分选纯度可达到90%以上，为下工序垃圾处理的“资源化、产业化”打下了坚实的基础。混合是垃圾，分类是资源。Waste Sorting SystemWaste separation has always been the bottleneck of waste disposaltechnology,whetherincineration,landfilltreatmentprocess,orintegrated treatment process. Many failures are due to garbage sort notcomplete, leading that the next process can not handle, and the wholeproduction line can not run properly. Municipal solid waste“LJ” Fivetreatmenttechnologies-the core technologyofthe waste sortingsystem,is the key technology. By garbage uniform feeding, automatic sortingsystem of bulky waste, bulky waste automatic crushing system, automatictorn bags of garbage bags, bulkyorganic matterautomatic broken system,closed mechanization winnowing system, plastic water selection system,and “ hotelection ” systemofhigh temperature andpressureofhydrothermal hydrolysis of organic matter, urban house refuse can beseparatedtomanykinds: 1)inorganic;2)sands; 3)organic;4)irrecoverablefuel(ifsupplemented bysimple manual sorting,hardplasticandrubberetc willbeseparated);5) filmplastic;6)ferromagnetic materialsThe sortingrate of theabove garbage can reachmore than 85%, the sortingrate of film plastic reaches more than 90%, lay a solid foundation fornext treatment of“Resource and Industrialize”Mixing is Rubbish, while Classifying is Resource二、有机物高温高压水解水热氧化制肥系统该系统是“ LJ”五化处理技术的核心技术之一，前处理系统分选出来的有机物 , 经高温高压水解水热氧化釜在温度 193 C、压力 1.25Mpa 的条件下，反应 2 小时，彻底消灭了病虫害和杂菌， 并使有机物中的大分子链断成易于农作物吸收的小分子链，由于有机物在高温高压反应过程中， 产生了大量的糖分和腐殖酸， 所以该肥料养分充足， 是绿色食品的必用肥料。 根据市场需求， 配入其它养分即可生产出各种高效有机无机复混生态农作物专用肥。以有机物为主的垃圾，经过 2 个小时左右的“水解”处理后，其中， 95%以上的有机垃圾在水解喷爆过程中被膨化成棕褐色粉末， 降解为有益于农作物生长的优质有机肥，然后经过烘干、筛分，把有机质粉末与其它未降解物彻底分离。该工序能将不可降解的无机物与有机物彻底分选开来，所以也叫“热选” 。该工序所需热能来自焚烧系统的余热锅炉， 能源循环利用， 以垃圾处理垃圾， 大大地降低了垃圾处理成本。高温高压水解水热氧化技术的作用：1,把大分子链断为短分子链。2,加速糖类、腐殖酸的转换，提高有机肥的质量。3,灭菌彻底，完全实现了无害化处理。Organic High Temperature and Pressure Hydrolysisand OxidationCompostingSystemThesystem isthecore technologyin“LJ” Fivetechnologies,organicsortedoutofpre-treatmentsystem,inhydrothermalhydrolysisoxidationreactor, with 193 ,1.25Mpa,the react for 2 hours, completely eliminatepests and bacteria, and make the macromolecular chain in organic matterbroken into easily absorbed by crops small molecules chain. Due to lotsofsugarandacidgeneratedfromthehightemperatureand pressurereactionprocessoforganicmatter,thefertilizerisnutrientadequacy,and a must fertilizerto green food.According tomarket demands, itcanbe blended with other nutrients to produce a variety of organic andinorganic specific ecological compound fertilizer for crops.Thegarbagedominatedbyorganicwaste,afterabout2hours“ hydrolysis ” treatment,morethan95% organicwasteofthemwereextrudedintobrown powders duringthehydrolysisjetexplosionprocess,and degrade toqualityorganicfertilizerbenefitforthe growthof crops.And though dryingand screening,absolutelyseparateorganicpowders andotherundegraded matter.Thisprocesscancompletelyseparatetheundegraded inorganicwaste and organicwaste, so called“hotelection ”.The heat required by this process from the waste heat boiler system canrecycle,usewasteto disposewaste,willgreatlyreducethewastedisposal costs.Theroleofhighpressureandtemperaturehydrothermaloxidationhydrolysis:Macromolecular chain is broken into shorter chainsAccelerate the conversion of sugars and humic acid, improve the quality of organic fertilizerComplete sterilization, the full realization of the sound processing三、不可回收类可燃物焚烧、余热利用系统经综合风选机分选出来的高热值可燃物，如竹木制品、硬质塑料、废橡胶、破衣物及其它可燃物， 具有不可回收、 但热值很高的特点， 此类垃圾配入能抑制和吸附氯化物、防止二恶英产生的添加剂和粘接剂， 按一定比例混合， 进入焚烧炉焚烧。由于添加剂对可燃物燃烧过程中产生的 Hce 气体有特殊的吸附作用，所以，有效地抑制了 “二恶英”一类有害气体的产生。 焚烧炉产生的热能供给余热锅炉，余热锅炉产生的过热蒸气供给本厂水解水热氧化制肥车间， 多余热能或发电或给居民集中供热或给酒店、宾馆、洗浴中心供热水。该焚烧炉为立式富氧焚烧炉， 可燃物进料自上而下， 焚烧炉火焰自下而上， 可燃物与火焰逆向而行， 边焚烧边烘干， 加之内部出渣炉箅为塔形旋转结构， 所以焚烧彻底，无需加煤或喷油。由于前分选分类比较彻底，很少有塑料焚烧，所以很少产生有害气体，大大节约了废气处理成本，为其它焚烧炉的五分之一。创新环保科技 , 提倡绿色焚烧。Non-recyclable fuel burn and residual heat utilize systemFuel of calorific value elected by integrated air separation unit, suchas wood products, rigid plastic, rubber, broken clothes and other fuel,are all irrecoverable and high calorific. We add some additives andadhesives, which have quality of inhibition and absorption of chloride,and can prevent the generation of dioxins into the incinerator. For thespecial absorption of Hce during the burning by additives, effectivelyinhibitthegenerationof harmfulgases, like“Dioxin ” .Theheatgenerated from the incinerator supply heat boiler, which can generatesuperheated steam supplied to hydrothermal oxidation of fat hydrolysisplant.And excessheatcan generatepower and central heatingsupplyforresidents, hotels, and bath center etc.The incinerator is vertical-type oxygen incinerator, fuel feed from thetop tothe bottom,reserve thelineofthe blame,burningwiththe drying,and grate within the slag is the rotating tower structure, so it cancompletely burn without adding coal or fuel. For the thorough sortingclassificationoftheformer,thereislittleplastictoburn,andgenerate littleharm gas, which significantlysaves the costof waste gastreatment, only one-fifth of other incinerators.Innovative Environmental Technologies, Promote Green incineration四、无机物制造建筑材料系统经综合风选机分选出来的无机物类垃圾、 可燃物类垃圾在焚烧过程中产生的炉渣用于制砖。由于炉渣是通过高温焚烧形成的产物，一方面自身具有一定的强度，相当于 110 号的成品水泥， 另一方面高温焚烧彻底， 无污染，符合 GB508.3-1996 危险废物鉴别标准浸出毒性鉴别 。本套系统产生的无机物垃圾、炉渣可以综合利用，将无机物垃圾、炉渣制成空心砖、道板砖等系列建材产品。既可增加垃圾处理厂的收入，减轻运行费用，又解决了无机物垃圾、炉渣的出路。主要品种为：增光西班牙道板、机压西班牙道板、增光草坪砖、机压六角砖、机压扭曲砖、机压彩色路沿石系列、机压空心砖等。生产的多孔固化垃圾多孔砖需达到烧结多孔砖 （GB13544-2000）的标准的同时，还需满足 Q/JK01-2004固化垃圾多孔砖的标准。Inorganic Building Materials Manufacture SystemInorganic garbage and slag generated by combustible waste in the incineration process, which is separated by integrated air separation unit can be used to make brick.
