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為垃圾分選不徹底， 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、 大塊有機物自動破碎系統(tǒng)、 全封閉機械化風(fēng)選系 統(tǒng)、塑料水選系統(tǒng)、有機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) 無機物類； 2) 砂土類； 3) 有機物類； 4)

2、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、 橡膠等）； 5) 薄 膜塑料類； 6) 鐵磁物類 . 以上垃圾，分選純度均可達到 85%以上，薄膜塑料分選純度可達到 90%以上，為 下工序垃圾處理的“資源化、產(chǎn)業(yè)化”打下了堅實的基礎(chǔ)。 混合是垃圾，分類是資源。 Waste Sorting System Waste separation has always been the bottleneck of waste disposal tec

3、hnology, whether incineration, landfill treatment process, or integrated treatment process. Many failures are due to garbage sort not complete, leading that the next process can not handle, and the whole production line can not run properly. Municipal solid waste “LJ” Five tre

4、atment technologies- the core technology of the waste sorting system, is the key technology. By garbage uniform feeding, automatic sorting system of bulky waste, bulky waste automatic crushing system, automatic torn bags of garbage bags, bulky organic matter automatic broken

6、rganic; 4) irrecoverable fuel (if supplemented by simple manual sorting, hard plasticand rubber etc will be separated); 5) film plastic; 6) ferromagnetic materials The sorting rate of the above garbage can reach more than 85%, the sorting rate of film pl

7、astic reaches more than 90%, lay a solid foundation for next treatment of“Resource and Industrialize ” Mixing is Rubbish, while Classifying is Resource 二、有機物高溫高壓水解水熱氧化制肥系統(tǒng) 該系統(tǒng)是“ LJ”五化處理技術(shù)的核心技術(shù)之一，前處理系統(tǒng)分選出來的有機物 , 經(jīng)高溫高壓水解水熱氧化釜在溫度 193 C、壓力 1.25Mpa 的條件下，反應(yīng) 2 小時，徹底消滅了病蟲害和雜

8、菌， 并使有機物中的大分子鏈斷成易于農(nóng)作物吸收的小分子鏈，由于有機物在高溫高壓反應(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)出各種高效有機無機復(fù)混生態(tài)農(nóng)作物專用肥。 以有機物為主的垃圾，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)有機肥，然后經(jīng)過烘干、篩分，把有機質(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物與有機物徹底分選開來，所以也叫“熱選” 。該工序所需熱能來自焚燒系統(tǒng)的余熱鍋

9、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, 把大分子鏈斷為短分子鏈。 2, 加速糖類、腐殖酸的轉(zhuǎn)換，提高有機肥的質(zhì)量。 3, 滅菌徹底，完全實現(xiàn)了無害化處理。 Organic High Temperature and Pressure Hydrolysis and Oxidation Composting System The system is the core technology in “LJ”

10、Five technologies, organic sorted out of pre-treatment system, in hydrothermal hydrolysis oxidation reactor, with 193 ℃,1.25Mpa,the react for 2 hours, completely eliminate pests and bacteria, and make the macromolecular chain in organic matter broken into easily absorbed by cro

11、ps small molecules chain. Due to lots of sugar and acid generated from the high temperature and pressure reaction process of organic matter, the fertilizer is nutrient adequacy, and a must fertilizer to green food. According to market demands, it can be blended

12、with other nutrients to produce a variety of organic and inorganic specific ecological compound fertilizer for crops. The garbage dominated by organic waste, after about 2 hours “ hydrolysis ” treatment, more than 95% organic waste of them were e

13、xtruded into brown powders during the hydrolysis jet explosion process, and degrade to quality organic fertilizer benefit for the growth of crops. And though drying and screening, absolutely separate organic powders and other undegraded matter. This process can comp

14、letely separate the undegraded inorganic waste and organic waste, so called “hot election ”. The heat required by this process from the waste heat boiler system can recycle, use waste to dispose waste, will greatly reduce the waste disposal costs.

15、 The role of high pressure and temperature hydrothermal oxidation hydrolysis: Macromolecular chain is broken into shorter chains Accelerate the conversion of sugars and humic acid, improve the quality of organic fertilize

16、r Complete sterilization, the full realization of the sound processing 三、不可回收類可燃物焚燒、余熱利用系統(tǒng) 經(jīng)綜合風(fēng)選機分選出來的高熱值可燃物，如竹木制品、硬質(zhì)塑料、廢橡膠、破衣物及其它可燃物， 具有不可回收、 但熱值很高的特點， 此類垃圾配入能抑制和吸附氯化物、防止二惡英產(chǎn)生的添加劑和粘接劑， 按一定比例混合， 進入焚燒爐焚燒。由于添加劑對可燃物燃燒過程中產(chǎn)生的 Hce 氣體有特殊的吸附作用，所以，有效地抑制了 “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

17、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)保科技 , 提倡綠色焚燒。 Non-recyclable fuel burn and residual heat utilize system

18、Fuel of calorific value elected by integrated air separation unit, such as wood products, rigid plastic, rubber, broken clothes and other fuel, are all irrecoverable and high calorific. We add some additives and adhesives, which have quality of inhibition and absorption of chlor

19、ide, and can prevent the generation of dioxins into the incinerator. For the special absorption of Hce during the burning by additives, effectively inhibit the generation of harmful gases, like “Dioxin ” . The heat generated from the incinerator supply heat boiler, whi

20、ch can generate superheated steam supplied to hydrothermal oxidation of fat hydrolysis plant. And excess heat can generate power and central heating supply for residents, hotels, and bath center etc. The incinerator is vertical-type oxygen incinerator, fuel fe

21、ed from the top to the bottom, reserve the line of the blame, burning with the drying, and grate within the slag is the rotating tower structure, so it can completely burn without adding coal or fuel. For the thorough sorting classification of the former, there

22、is little plastic to burn, and generate little harm gas, which significantly saves the cost of waste gas treatment, only one-fifth of other incinerators.
