【正文】 城市垃圾分選系統(tǒng) 設計說明書 1 某城市生活垃圾綜合分選處理系統(tǒng)設計 中文摘要 固體廢棄物處理通常是指通過物理、化學、生物、物化及生化方法把固體廢物轉(zhuǎn)化為適于運輸、貯存、利用或處置的過程。垃圾分選，是垃圾處理技術的瓶頸，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，導致下工序無法處理而使整條生產(chǎn)線都不能正常運行。 本文以設計處理量為 400t/天的某城市生活垃圾分選處理系統(tǒng)為目標，確定了垃圾分選系統(tǒng)中的垃圾儲料車間，行車與抓斗，破碎，篩分，風選等的工藝設計參數(shù)以及設計依據(jù)。同時確定了整個垃圾綜合分選處理系統(tǒng)的 工作流程、以及廠址的選擇，廠區(qū)的布置。每天可產(chǎn)生金屬 、玻璃 、可以進行堆肥的 、需要進行填埋的 。具有很好的環(huán)境效益、經(jīng)濟效益和社會效益。 關鍵詞 ： 城市生活垃圾，綜合分選處理，工藝流程設計，效益分析 THE DESIGNING OF A SORTING SYSTEM OF THE MUNICIPAL SOLID WASTE(MSW) DISPOSAL English Abstract Solid waste treatment usually refers to pass the physical, chemical, biological, chemical and physical way to solid wastes as for transportation, storage and use or disposal of solid wastes. Garbage sorting, is the bottleneck of the waste treatment technologies. Whether burning landfill process, or integrated treatment technology. Because of the garbage separation is not plete, lead to next procedure can39。t deal the whole production line can normal operation. In this paper. the design capacity for 350 t/a day of urban living garbage sorting processing system for the target, And make sure the garbage sorting processing prehensive work flow of the system, and the choice of the site, the arrangement of the factory. Every day can produce metal t/d, glass t/d, can the t/d, the need for t/d. It’s good for environmental benefits, economic benefit and social benefit. Key words: City life rubbish, prehensive treatment, sorting process design, benefit analysis 城市垃圾分選系統(tǒng) 設計說明書 2 目錄 第一章 緒 論 ................................................................................................................... 3 ........................................................ 3 ............................................ 3 ................................................ 3 ............................. 3 .......................................... 4 .............................................. 4 ........................................ 4 本課題研究的目的與意義 .............................................. 5 ...................................................... 5 ...................................................... 5 ...................................................... 5 ...................................................... 6 第二章 生活垃圾分選處理工藝設計 ............................................................................... 7 廠址選擇 ........................................................... 7 (見附圖 ) ................................................ 7 ...................................................... 7 ...................................................... 7 垃圾分選工藝設計計算 ................................................ 7 ............................................ 7 .............................................. 8 .................................................... 9 、抓斗的選擇 .............................................. 9 磁選設備的選擇 .............................................. 10 ............................................... 10 ................................................... 12 ..................................................... 13 ....................................................... 14 環(huán)境保護 .......................................................... 18 第三章效益分析 ............................................................................................................. 19 ......................................................... 19 ....................................................... 19 ....................................................... 20 ....................................................... 21 第四章 總 結(jié) ........................
