垃圾分選系統(tǒng).doc

1、一、 垃圾分選系統(tǒng)垃圾分選，歷來是垃圾處理技術(shù)的瓶頸，不管是焚燒、填埋處理工藝，還是綜合處理工藝，很多失敗案例都是因?yàn)槔诌x不徹底， 導(dǎo)致下工序無法處理而使整條生產(chǎn)線都不能正常運(yùn)行。城市生活垃圾“ LJ”五化處理技術(shù) - 垃圾分選系統(tǒng)，是該技術(shù)的核心， 該系統(tǒng)通過垃圾均勻給料、 大件垃圾自動分選系統(tǒng)、 大件垃圾破碎系統(tǒng)、袋裝垃圾自動破袋、 大塊有機(jī)物自動破碎系統(tǒng)、 全封閉機(jī)械化風(fēng)選系統(tǒng)、塑料水選系統(tǒng)、有機(jī)物高溫高壓水解水熱氧化“熱選”系統(tǒng)等工藝處理后，可將城市生活垃圾分選為： 1) 無機(jī)物類； 2)砂土類； 3) 有機(jī)物類； 4)不可回收可燃物類 （若輔以簡單人工分選， 還可以分出硬質(zhì)塑料、

2、 橡膠等）； 5)薄膜塑料類；6)鐵磁物類 .以上垃圾，分選純度均可達(dá)到 85%以上，薄膜塑料分選純度可達(dá)到90%以上，為下工序垃圾處理的“資源化、產(chǎn)業(yè)化”打下了堅實(shí)的基礎(chǔ)。混合是垃圾，分類是資源。Waste Sorting SystemWaste separation has always been the bottleneck of waste disposaltechnology,whetherincineration,landfilltreatmentprocess,orintegrated treatment process.

7、高壓反應(yīng)過程中， 產(chǎn)生了大量的糖分和腐殖酸， 所以該肥料養(yǎng)分充足， 是綠色食品的必用肥料。 根據(jù)市場需求， 配入其它養(yǎng)分即可生產(chǎn)出各種高效有機(jī)無機(jī)復(fù)混生態(tài)農(nóng)作物專用肥。以有機(jī)物為主的垃圾，經(jīng)過 2 個小時左右的“水解”處理后，其中， 95%以上的有機(jī)垃圾在水解噴爆過程中被膨化成棕褐色粉末， 降解為有益于農(nóng)作物生長的優(yōu)質(zhì)有機(jī)肥，然后經(jīng)過烘干、篩分，把有機(jī)質(zhì)粉末與其它未降解物徹底分離。該工序能將不可降解的無機(jī)物與有機(jī)物徹底分選開來，所以也叫“熱選” 。該工序所需熱能來自焚燒系統(tǒng)的余熱鍋爐， 能源循環(huán)利用， 以垃圾處理垃圾， 大大地降低了垃圾處理成本。高溫高壓水解水熱氧化技術(shù)的作用：1,把大分子鏈斷

8、為短分子鏈。2,加速糖類、腐殖酸的轉(zhuǎn)換，提高有機(jī)肥的質(zhì)量。3,滅菌徹底，完全實(shí)現(xiàn)了無害化處理。Organic High Temperature and Pressure Hydrolysisand OxidationCompostingSystemThesystem isthecore technologyin“LJ” Fivetechnologies,organicsortedoutofpre-treatmentsystem,inhydrothermalhydrolysisoxidationreactor, with 193 ,1.25Mpa,the react for 2 hours, c

14、地抑制了 “二惡英”一類有害氣體的產(chǎn)生。 焚燒爐產(chǎn)生的熱能供給余熱鍋爐，余熱鍋爐產(chǎn)生的過熱蒸氣供給本廠水解水熱氧化制肥車間， 多余熱能或發(fā)電或給居民集中供熱或給酒店、賓館、洗浴中心供熱水。該焚燒爐為立式富氧焚燒爐， 可燃物進(jìn)料自上而下， 焚燒爐火焰自下而上， 可燃物與火焰逆向而行， 邊焚燒邊烘干， 加之內(nèi)部出渣爐箅為塔形旋轉(zhuǎn)結(jié)構(gòu)， 所以焚燒徹底，無需加煤或噴油。由于前分選分類比較徹底，很少有塑料焚燒，所以很少產(chǎn)生有害氣體，大大節(jié)約了廢氣處理成本，為其它焚燒爐的五分之一。創(chuàng)新環(huán)?？萍?, 提倡綠色焚燒。Non-recyclable fuel burn and residual heat util
