用生活垃圾和 /或有机废弃物制取烃类的
方法和设备 本发明领域 设备,特别是通过热裂解和催化裂解从生活垃圾和 /或有机废弃物 中制取烃类的方法和设备。 本发明技术背景
随着社会的发展和人们生活水平的提高,生活垃圾以及垃圾中 有机物成份含量不断提高, 并对人类的生存环境产生严重危害。有 效地处理这些废弃物使其无害化、资源化已成为全球普遍重视和研 究的课题。 生活垃圾成份复杂。现有技术中的焚烧法存在着投资大、尾气 污染大气、 余热发电成本高等弱点。 填埋法则存在大量占用耕地、 污染水源、 不能资源化的严重弊病。 现有技术已公开了一些解决此方面问题的技术方案, 例如: Chambers在 USP4, 235, 676中公开了由废轮胎和工业及生活废弃物 制取烃类的设备, 所公开的设备采用真空系统和固定反应釜, 因而 反应易结焦, 排渣难, 且生产不能连续性进行。 在 EP-A- 0607862 (申请人为 Mazda Motor Coporation)公升了 一种从废塑料或废橡胶制取烃类的方法和设备, 反应釜为立式, 其 中没有公开反应残渣的排放方法, 以上方法均不能同时和连续处理 成份复杂的生活垃圾和 /或有机废弃物。 本发明申请人在 PCT/CN97/00124 中, 公开了从有机或高分子 废弃物制取烃类的方法及设备, 采用卧式旋转裂解反应釜。 由于裂 解反应的全过程是在同一个反应釜中进行, 必须维持反应釜处于高 温状态下才能满足裂解反应所需热量。但高温状态下的对反应釜材 质要求严格, 而普通钢材易受热变形, 使反应釜旋转困难。 如使用 普通材质, 生产中只能降低反应温度来保持反应釜不变形, 如此则 导致裂解反应不完全, 使得原料的分解不彻底。裝料和排渣均属间 歇式。 本发明人为解決现有技术中的种种问题, 提出本发明。 本发明概述
因此, 本发明的目的是提供从生活垃圾和 /或有机废弃物中制 取烃类的方法和设备。 更具体地, 本发明提供将原料进行不同温度 下的两級裂解, 通过连续进料和连续排渣, 从生活垃圾和 /或有机 废弃物中制取烃类的方法和设备。 本发明中, 处理过程为两步进行, 在第一反应釜(卧式旋转反 应釜)中进行第一級裂解, 其中, 反应釜设计为较大体积, 以便尽 可能多地处理原料, 其具体尺寸可根据待处理原料的供应等情况而 定, 通常情况下可设计直径为 1. 0- 3. 0米。 原料经过第一反应釜裂解后, 引出裂解的气相成分。剩余成分 排入第二反应釜(螺旋搅拌反应釜)中, 此时原料的体积已大大減 少, 所以第二反应釜可以设计成体积较小的, 其具体尺寸可根据处 理原料的性质及条件而定, 通常情况下, 第二反应釜可设计为直径 约是第一反应釜直径的 1/2, 如设计为 0, 5- 1. 5米。 第二反应釜的裂解温度要大大高于第一反应釜,但由于其体积 较小, 且反应釜的圆柱形壳体固定不动, 所以在一定高温下反应釜 不易变形, 即使有轻微变形, 也不会影响其中裂解反应的进行, 因 而克服了现有技术中存在的问题。 本发明提供处理生活垃圾和 /或有机废弃物的方法, 包括: 将原料输入卧式旋转反应釜中, 进行第一級裂解反应; 以及 将经第一級裂解反应后的剩余成分输入螺旋搅拌反应釜中进 行第二級裂解反应。 上述方法中还包括分别收集第一和第二反应釜中引出的气相 烃的步骤。 所述方法中, 如需要, 反应原料可以进行预处理。 所述方法中,第一级裂解反应和第二級裂解反应包括热裂解反 应和 /或催化裂解反应。 所述的裂解反应可維持在常压或高压下进行, 通常在 0. 02 - 0. 6MPa下进行。 第一级裂解反应温度为 350-600 °C, 第二級裂解反 应温度为 600- 1200 °C。优选地,第一級裂解反应温度为 400- 500 °C, 第二级裂解反应温度为 600- 800 °C。 所述催化裂解反应所用的催化剂为 SR- 1型催化剂。 本发明还提供处理生活垃圾和 /或有机废弃物的设备, 主要包 括卧式旋转反应釜和螺旋搅拌反应釜。 所述卧式旋转反应釜包括: 圆柱形壳体; 圆形齿轮盘, 套在圆 柱形壳体外筒壁上; 圆形螺紋钢带, 均匀固定在壳体的内壁; 进料 器, 配置于卧式反应釜的一端; 第一处理室, 配置于卧式反应釜的 另一端(末端)。 所述的卧式旋转反应釜进一步包括内部加热装置。 所述的进料器包括: 螺旋进料器或活塞往复式进料器。 所述螺旋搅拌反应釜包括: 圆柱形壳体, 其一端与第一处理室 连接; 螺旋搅拌机, 安装在圆柱形壳体内部; 第二处理室, 配置于 圆柱形壳体的另一端; 以及螺旋排渣器, 配置于第二处理室的底 部。 所述的第一处理室和第二处理室中包括固定床,其分别置于第 一和第二处理室内部的上方。 本发明的设备, 根据需要, 还包括预处理装置, 通过它除去原 料中的水份。 预处理装置可以设针为类似于第一反应釜的形状,只是其热源 可以通过热气供给, 不需要第一反应釜那样高的温度。 本发明的设备进一步包括烃油收集装置,为本领域中常规使用 的汽油分离装置, 如可包括: 冷凝塔, 烃油收集罐和水封罐等。 附图的简要说明

(13)直接落入另一螺旋搅拌反应釜(26)中, 反应产生的气相烃进入 固定床(14)与固定床(14)中的催化剂发生催化裂解反应 [如果固定 床(14)中没有催化剂, 则不发生催化裂解反应]。 反应生成的气相 烃经釜出口(15)流入冷凝器(23), 然后进入烃油收集罐(24)。烃油 可以按传统炼油方法进一步分馏提纯成汽油、 柴油和重油。 重油可 以再返回到反应釜(1)进行裂解或作为商品燃料油出售。 不被凝结 的气体进入水封罐(25), 并从水封罐(25)顶部排出, 返回到燃烧炉 (10)中燃烧再利用 。 此卧式旋转反应釜(1)具有物料不易结焦、 传 热效率高、 反应速度快、 生产连续化的特性。 然而, 为了满足工业 化生产要求, 此卧式旋转反应釜(1)必须具备相适应的容积。 反应 釜(1)的圆柱形筒体越长或直径越大, 都能增大反应釜容积, 但容 积增大导致反应釜的钢材在高温条件下容易受热变形, 导致反应釜 旋转困难。 因此, 采用较低温度条件有利于设备正常运转。 但是, 低温导致裂解反应不完全, 反应残存物中还有一定量的有机物成份 未被分解, 需要继续进行第二級高温条件下裂解反应, 以确保残渣 不含有机成份, 实现垃圾的无害化。 第二級高温裂解反应是在另一螺旋搅拌反应釜(26)中进行。用 煤、 重油或可燃性气体在燃烧炉(10)中燃烧生产高温烟道气经孔 (12)和加热室(11)给螺旋搅拌反应釜(26)供热, 用调速电机(4)驱 动釜(26)中螺旋搅拌机(19)转动, 经第一級裂解反应产生的残存物 在此螺旋搅拌反应釜(26)中发生第二級更高温度下的裂解反应。经 第一次裂解后, 残渣量減少, 该螺旋搅拌反应釜(26)直径也相应地 減小, 圆柱形壳体(21)固定不动, 所以在一定的高温状态下反应釜 (26)不易受热变形, 即使有轻微的变形, 也不影响反应釜(26)中螺 旋搅拌机(19)的旋转。 由于第二次裂解反应温度高, 残渣中的有机 物成份被深度裂解, 彻底分解变成气相烃, 气相烃进入釜(26)内固 定床(16)发生催化裂解反应,催化反应所需热量由反应釜(26)内热 量供给, 催化反应产生气相烃排出反应釜(26)后, 流入冷凝器(23) 并进入烃油收集罐(24), 不凝结的气体入水封罐(25), 并从罐(25) 的顶部排出, 返回到燃烧炉(10)中燃烧回收利用。 第二级高温裂解 反应剩余的残渣已成为无机残渣, 在螺旋搅拌机(19)的搅拌推动 下,排入反应釜(26)的第二处理室(27)底部,经底部螺旋排渣器(29) 的作用排出釜外。 经粉碎、磁选、提纯后得到无机填料和金属等工 业原料。 以下通过具体实施例更详细地说明本发明,但本发明并不受其 限制。 实施例 1 将北京冬天得到的生活垃圾用破碎机破碎成 35厘米以下的块 状物(不需分选), 经预处理 (脱水) 后, 用提升机装入料仓(28)和 螺旋进料器(3)中, 通过螺旋进料器(3)的旋转推动装入密闭的卧式 旋转反应釜(1)中。 反应釜(1)内的固定床(14)中装入一定量的 SR- 1型催化剂。驱动反应釜(1)旋转, 用燃烧炉(10)中产生的高温烟道 气给加热室(11)中的反应釜(1)供给热量。釜(1)中的物料在旋转滚 动和受热时发生第一級热裂解反应和催化裂解反应。 裂解反应在 0. 02-0. 3MPa及 400 - 500 °C条件下进行, 反应中产生的气相烃不断 地排出釜(1)外, 经冷凝器(23)流入烃油收集罐(24) , 成为低沸点 烃油。 不被凝结的可燃性气体 和 ( 4烃类通入水封罐(25) , 从 罐(25)顶部返回到燃烧炉(10)中燃烧回收再利用。第一級裂解反应 产生残渣落入第一处理室(13) , 并直接落入另一螺旋搅拌反应釜
(26)中, 进行第二级高温裂解反应, 用燃烧炉(10)中产生的高温烟 道气给反应釜(26)供热。反应在 0. 02-0. 3MPa及 600- 800 °C条件下 进行。第二級热裂解反应产生的气相烃不断地进入第二处理室(27) 内上方的催化固定床(16)中, 与固定床( 16)的 SR - 1型催化剂接触, 发生第二級催化裂解反应,催化反应所需热量由反应釜(26)内热量 供给。裂解反应剩余的无机残渣不断地排入反应釜(26)第二处理室
(27), 并经收集室(27)底部的螺旋排渣器(29)排出釜(26)外。 经粉 碎、磁选和分离提纯得到工业无机填料和金属, 作为商品出售。催 化反应所产生的低沸点气相烃流入冷凝器(23), 然后进入烃油收集 罐(24)成为低沸点的烃油。把第一、 二級裂解反应所收集的低沸点 烃油, 采用传统的炼油方法及设备进行分馏、 冷凝或提纯。 原料和经过上述裂解反应结果分析如下:
