说明书 一种含有机质废弃物的两级等离子体气化熔融裂解方法及其装置 技术领域
本发明涉及一种含有机质废弃物的的处理方法,具体涉及一种含有机质废弃物的两级 等离子体气化熔融裂解方法及其装置, 属气化熔融裂解技术领域。 背景技术
中国发明专利竹田 繁司等人 CN 1935399A一种有机物垃圾的分解处理方法及有机 物垃圾热分解器,介绍了释电材料在一定温度下释放电子作不规则运动,在周围设置的永 久磁场作用下, 激励加速螺旋运动, 伴随相互撞击, 轰击有机物质产生正离子和电子, 诱 发电晕等离子体反应, 出现极不稳定电场。而新产生的正离子和电子, 又随机地倍增诱发 电晕等离子体反应,使临近有机质产生正离子和电子,从而产生链式电晕热等离子体反应。 进而将有机质气化分解为水蒸气、带有负离子的气体和少量带有负离子的灰烬。经过空气 磁化器, 带有负离子的空气, 进入电晕等离子体反应区域, 在受扰动的原始磁场和不稳定 电场的共同激励下,产生紊流,促进链式电晕等离子体反映扩散开来,加速有机质的气化, 取得了较好的效果。但是出现的问题之一是,不便于处理含有大量无机质尤其是陶瓷和金 属废弃物, 特别是危险废弃物不能处理; 问题之二是由于反应温度一般在 150〜650°C, 会不可避免的产生焦油和二噁英;问题之三是使用得空气磁化器,并没有改变空气的组分, 大量的氮气带入, 只会加重后续尾气处理***的负担; 问题之四空气磁化器磁性较弱, 使 得空气离子化较弱,反应器中有机质的热解速度缓慢; 问题之五是高磁能积永久磁铁没有 设置冷却***, 显然永久磁铁由于居里点温度效应, 长期处于较高温度下, 会发生退磁, 直接会导致磁控等离子体效果的衰退; 问题之六, 所产灰渣必需额外处理, 特别是富集毒 性灰渣更需特殊处理。
国际专利山本 正一的 W0 2009/08463 K 日本专利青木 硕志等人的特开 2010-58103 与河源 武史等人的特开 2008-175511、 中国专利平久井健三的 CN 201069309Y和原田义 和等人的 CN2860646Y基本原理与中国发明专利竹田 繁司等人 CN 1935399A相似, 只是 反应器结构上有区别, 仍都存在上述六大问题, 即使经过结构上改进, 可以处理一些带有 少数量无机物质组分的废弃物,但得到的含有金属、陶瓷等混合灰渣仍需要后续工艺特别 处理。
日本专利中岛 和也等人的特开 2007-105703 中介绍了一种磁流体和磁单元处理器, 主要利用了 HALBACH阵列的高磁能积永久磁体组合体内部通道形成的高场强磁场, 将 流经此通道的流体进行磁化, 得到含有离子特性的活性流体。 比如, 此流体是空气, 则可 以得到与其它物质反应活性高的空气,但是空气组分并没有改变。如果应用到有机物质的 热解方面, 则占有空气的近 3/4的氮气几乎没有起到有效的作用, 反而会给后续尾气处理 带来不必要的负担。
本人的中国专利 CN 101088581、 CN 101648200和 CN 201496973U 中注重的是将废弃 物直接一步进入等离子体弧区熔融裂解, 虽然可一步回收金属、 玻璃体和合成气, 但是电 能消耗较高, 而且飞灰量较大, 如果后续燃气发电, 可能发出的电力不能自给自足。 发明内容

图 4与图 5是磁控等离子体气化室 2横截面和纵剖面结构示意图。中空外壳 201和内 胆 202共同组成三层炉壳, 在中空外壳 201和内胆 202之间填充有释电矿物材料 207, 内 胆 202在释电矿物材料 207填充高度以下部位设置栅形孔 213,便于释电矿物材料 207溢 出的电子进入磁控等离子体气化气化区域 208。在中空外壳 201和内胆 202之间设置高磁 能积的水冷永久磁体 205, 并且水冷永久磁体 205在内胆 202的内侧 N、 S极相间而设, N、 S极间距 20〜40CM, 从而使得进入磁场区域的离子、 电子在洛仑兹力作用下, 呈螺旋 式运动, 便于多次轰击有机质, 有机质在离子、 电子的轰击下, 产生正、 负离子及电子, 同时这些正、 负离子及电子, 在磁场控制下, 又继续在洛仑兹力作用下, 呈螺旋式运动, 再次轰击有机质, 再次产生正、 负离子及电子, 形成倍增诱发电晕等离子体反应。磁控等 离子体气化室 2, 通过磁控等离子体气化室底座法兰 209、 磁控等离子体气化室顶部法兰 211用螺栓分别与多功能脉冲强化旋风效应室 3和可控布料式料仓 1相连接,连接处保证 良好的密封效果。在磁控等离子体气化室 2的上部侧面设置气化剂补给口 210, 根据需要 添加气化剂, 气化剂可以使氧气、水蒸汽和或空气等。在磁控等离子体气化室 2的中部和 底部分别设置热电偶 206和 215,以便对磁控等离子体气化区域的不同位置进行测温监控, 进而可以调节气化剂的加入量和或废弃物的加入高度和进料速度。在磁控等离子体气化室 2的上、 下部分别设置有密封式瞭望窗口 212、 密封式检修孔 214, 对于设备维护和废弃 物气化状况观察都起到了重要作用。
磁控等离子体气化区域内, 气化温度从上至下可以控制在室温〜 95CTC范围内。
在由中空外壳 201和内胆 202共同组成三层炉壳上连接有含有低密度等离子体富氧空 气发生器 203 , 该发生器根据需要可以是图 6中所示的, 也可以是图 9中所示多级磁场 处理器, 每个磁场处理器, 又由 4个磁场处理单元 Ml、 M2、 M3、 M4按照图 7、 图 8所 示螺旋式前进状磁场布置而成。 图 6 含有低密度等离子体富氧空气发生器磁场处理单元 横截面结构示意图, 图 7 含有低密度等离子体富氧空气发生器磁场处理器结构示意图, 图 8 含有低密度等离子体富氧空气发生器磁场处理器的 4个磁场处理单元 M M2、 M3、 M4的螺旋式磁场布置示意图, 图 9是含有低密度等离子体富氧空气发生器多级磁场处理 器串联示意图。 如图 7所示, 每个磁场处理单元磁极由两种高磁能积永久磁体组合而成, 分别是无孔永久磁体 20301、 有孔 (N2溢出通道) 永久磁体 20302, 无孔永久磁体 20301 分布在磁场处理单元的 4个角部, 有孔(N2溢出通道)永久磁体 20302分布在正方形的 4 个边的中部, 但这些有孔(N2溢出通道)永久磁体 20302的充磁方向与所处的位置有关, 同样 4个角部的无孔永久磁体 20301的充磁方向及其布置也并非随便, 8块永久磁体组合 是按照 HALBACH方式排列的。 为了使磁场单元处理器内部通道中磁场达到最强, 一般 使得内部空气通道磁场强度比常规排列方式磁场强度增至 1.5〜3倍, 在此通道内设置有 孔 (N2溢出通道) 山形磁极头 20305, 和有孔 (N2溢出通道) 抗磁质山形结构体 20306, 更加增大了此区域的磁场梯度值, 在此处梯度磁场作用, 顺磁性氧气聚集于通道之中, 而 抗磁性氮气则通过设置在永久磁体上 N2溢出通道 203021与磁极头贯穿的小孔 N2溢出通 道 203051和有孔(N2溢出通道)抗磁质山形结构体 20306上小孔 N2溢出通道 203061顺 利溢出, 从而完成氧气的聚集; 溢出的氮气汇集通过有孔 (N2溢出通道) 抗磁质封堵板 20308的 N2溢出通道 203081溢出磁场处理器。 4个磁场处理单元按照内部空气呈现旋流 方式组合为磁场处理器,在每个磁场处理单元之间采用抗磁质隔离板 20309进行隔离,尽 量避免各单元磁场的相互干扰。 磁场处理器的采用外壳抗磁方管 20304 , 内壳采用抗磁 有孔 (Ν^≤出孔) 方管 20303, 其上有 203031 出孔, 这些设计均是为氮气的顺利外 排的结构上的保证。为了得到较好的处理效果,我们还可以将多个磁场处理器用抗磁质出 气管 20312及抗磁质连接弯管 20311相互连接,形成多级磁场处理器。多级磁场处理器抗 磁质进气管 20307连接有气阀 20310, 可以对空气的进入量进行有效的控制。
由于氧气顺磁性和氮气等气体的抗磁性, 在梯度磁场中, 聚集氧气, 排斥氮气, 而且 磁场越强, 磁场梯度越大, 越有利于氧气的聚集, 科技界已成共识, 在此不再重复介绍其 机理。但是在磁场中可以使氧气得到活化, 产生低密度等离子体, 还鲜为人知。将高磁能 积永久磁体按照 HALBACH阵列排列成方形管段状磁场处理单元 Ml、 M2、 M3、 M4, 使得内部空气通道磁场强度比常规排列方式磁场强度增至 1.5〜3倍, 在此通道内设置山 形磁极头, 更加增大了此区域的磁场梯度值; 4个磁场处理单元按照内部空气呈现旋流方 式组合为磁场处理器,在每个磁场处理单元之间采用抗磁质隔离板 20309进行隔离,尽量 避免各单元磁场的相互干扰。为了得到较好的处理效果,我们还可以将多个磁场处理器串 联形成多级磁场处理器。
由于构成物质的基本粒子——电子自旋(自禀)运动, 导致自旋电子产生电磁以太蜗 旋形成磁偶极和磁矩, 因此所有化学元素的原子进入一定强度的磁场中, 当电子自旋磁极 和外磁场的方向相反时,在磁力作用效应达到或超过该元素的电离能时, 电子就可以挣脱 原子核的吸引成为光电子, 即产生量子跃迁现象。 电子受激发使原子的基态进入激发态, 实现了从磁能到电离能的转化, 显然, 磁的电离效应与磁的穿透作用有密切的联系。 磁场磁能的计算公式是 W = j'ii >H, 其中 W表示磁场磁能, H、 B分别为磁场强 度和磁感应强度,积分遍及磁场存在的空间,这表明可以将磁场存在的空间分成无数体积 元, 即每个体积元的磁能为 dv, 总的磁能则是他们的求和 (积分)。 磁场能量密度 ' I , 由于高磁能积钕铁硼材料, 随着金属钕的含量增加, 磁能积从 260kJ/M3已 经可以增到 500 kJ/M3以上, 再加上 HALBACH阵列的特殊性, 这里的磁场处理单元通道 内的磁场能量密度已可高达 650 kJ/M3以上。 又由于氧元素和氮元素的第一电离能分别为 13.618eV 和 14.53eV, 换算可得氧元素和氮元素的第一电离能分别为 1313.95kJ/mol 和 1401.95kJ/mol , 如不考虑其它因素, 氧元素和氮元素的第一电离能又可分别换算为 58685.5kJ/NM3和 62486.4 kJ/NM3。 显然该磁场处理单元通道内可以为空气中氧气和氮气 电离提供了足够的磁能, 也就是说, 在该磁场处理单元通道内可以电离约 1%的空气, 其 中氧气电离能力是氮气电离能力的 1.07倍。 如果考虑多级处理, 在加上氧气的逐级含量 数值增加, 小部分电离后的富氧空气, 出现了低密度等离子体和活性氧。
作为气化反应基本热量的保证, 通过独创的含有低密度等离子体的富氧空气发生器, 为链式电晕等离子体反应提供含有低密度等离子体的富氧空气,富氧空气中的低密度等离 子体中的正负离子、 自由电子在进入磁场后, 在洛伦兹力作用下, 作螺旋式运动, 轰击有 机质, 强化了已有的电晕等离子体反应; 低密度等离子体的富氧空气中活性氧, 如单线态 氧 (singlet oxygen), 它是基态氧接受了磁能而转变成的。 单线态氧有两种: §02状态比 基态氧的能量高出 93.7kJ(22.4kcal) ; l∑g+状态则更活泼比基态氧的能量高出 156.9kJ (37.5kcal), 从而更使得等离子体气化进程加快了速度。
一般情况下, 该磁场处理器可以富集增加氧气近 1〜3个百分点, 而燃烧反应中参与 反应空气中每增加 1个百分点氧气, 就可以增加反应温度约 50°C, 所以根据气化反应所 需控制温度,选择磁场处理器的串联级数,这也就是此处根据需要设置多级磁场处理器的 主要原因。
图 10与图 11是多功能脉冲强化旋风效应室 3正视俯视结构示意图。之所以称之为多 功能, 是因为, 在这里作为 "炉腰", 它不仅对上部的磁控等离子体气化室 2和下部等离 子体弧熔融裂解室 5起到承上启下的作用,而且在这个区域还完成了另外 3项功能,具体 说明如下:
在多功能脉冲强化旋风效应室 3的外壳双层中空蒸汽产生器 307上设置了与其相贯通 的中空水冷十字齿轮支持架 301,在这个中空水冷十字齿轮支持架 301之上通过设置 4个 齿轮支持轮 302支撑着可以旋转的大齿轮 303, 在小齿轮驱动减速电机 317和小齿轮 305 的驱动下, 大齿轮 302得以旋转。 大齿轮 302的轮辐上设置有带有炉箅子 320。 在齿轮中 心定位销 304上根据需要, 可以设置与大齿轮 302 同步旋转的拨料器, 以防止上部废弃 物在气化过程中结块。磁控等离子体气化室 2产生的气化气在下部等离子体弧熔融裂解室 5内负压牵引下下行, 灰烬及其它金属等无机物通过炉箅子 320, 落入下部等离子体弧熔 融裂解室 5, 未彻底气化成小分子的有机物残物及中间长链焦油、残碳也随之进入等离子 体弧熔融裂解室 5, 这是作为 "炉腰"起到的承上启下的重要的炉箅子隔离作用。
双层中空蒸汽产生器 307上设置的气囊 308上, 布置有脉冲电动文丘里喷嘴 (4套) 309, 脉冲气体可以采用氮气、 水蒸气、 和或空气, 在脉冲气体作用下, 使得多功能脉冲 强化旋风效应室 3中呈现脉冲强化旋风效应,使得气化气携带的大量粉尘滞留于耐火材料 炉壁上, 同时增长了气化气在装置内的停留路径, 达到一定厚度或熔化、 软化点, 沿炉壁 流下进入等离子体弧熔融裂解室 5熔池 512。这称之为脉冲强化旋风效应完成炉内拦截飞 灰主要作用, 同时延长气化气的炉内停留时间。
上部磁控等离子体气化室产生的气化气往往需要重整,作为重整用过热水蒸气的产生 便在双层中空蒸汽产生器 307里, 所以其上设置必须的液位计 314、 水蒸气出口管 306、 冷水补入口 319、 调整产气量用热水排出口 321, 气化重整用水蒸气入口 318。
由于本装置为了使等离子体弧熔融裂解室 5熔池 512 中的金属熔体和玻璃体出炉顺 畅,整个装置设置旋转机构,旋转轴就设置在多功能脉冲强化旋风效应室 3的外壳双层中 空蒸汽产生器 307上,为了使合成气顺利与合成气净化***对接,又由于对接位置要相对 静止, 将合成气出口设置在中空旋转轴内, 左右中空轴的端部均设有中空轴法兰 310。 左 中空轴 316内设置热电偶 315, 用于测量多功能脉冲强化旋风效应室 3内温度, 作为合成 气通道右中空轴 311附近又设置水冷垂直合成气通道 312并与之贯通,而水冷垂直合成气 通道 312下方与等离子体弧熔融裂解室 5上设置的出炉合成气水冷器 502实现密封对接。
图 12与图 13是等离子体弧熔融裂解室 5正视与俯视结构示意图, 在此室内, 金属重 熔,其他无机物玻璃化,残余有机物包括中间有机物焦油等彻底裂解为对环境友善的小分 子气体 CO、 H2、 HC1等, 残碳在水蒸气等离子体弧作用下, 完成彻底转化和或煤气化反 应, 得到可回收的贵重金属、 可直接用于建材领域的玻璃体、 富氢高能合成气, 这也是本 发明的基本点之一。
在等离子体弧熔融裂解室 5上设置有直流等离子体弧发生器 501及其拖动*** 50101, 为室内反应提供 3000°C〜10000°C的等离子体弧高温区,保障等离子体弧熔融裂解室 5"炉 膛"温度在 1250°C〜1550°C,保证合成气出炉温度为 1250°C。直流等离子体弧发生器 501 可以使用中心带孔通入水蒸汽等载气的石墨电极,也可以使用转移弧或非转移弧水冷金属 等离子体弧炬,直流等离子体弧发生器 501数量至少 1个,为了调节多个直流等离子体弧 发生器与熔池的距离, 在炉底耐火材料中设置炉底电位测试引出极 503, 用于取出电位信 号。合成气出炉通道 505设置在熔池上方侧面耐火材料 511炉壁上,与之密封对接的是的 出炉合成气水冷器 502,其上设有合成气水冷器密封盖 50201、合成气水冷器出水口 50202、 合成气水冷器进水口 50203、 合成气水冷器对接法兰 510。 为了设备运行时便于控制, 在 等离子体弧熔融裂解室 5上还分别设置有观测孔通道 506, 观测孔密封盖 50601, 高温摄 像*** 507。 熔池 512中玻璃体以及金属熔体通过 508 水口 I渣口通道和水 I渣咀 509 允许渣金同流出炉浇注,在锭模中完成自然分层,也可以分别设置渣口和水口,分别浇注。 测温热电偶 513可以准确反馈出等离子体弧室平均温度,测温热电偶 514可以准确反馈出 合成气的出炉温度。 为了便于检修, 在等离子体弧熔融裂解室 5上还设置有检修孔 504, 其上通过检修孔密封盖 50401进行可靠密封。
特别说明, 由于下部等离子体弧热量辐射和传导,在上部的磁控等离子体气化室的物 料还可以接受预热,因此对于含有机质较少的危险废弃物如垃圾焚烧飞灰和或合成气净化 飞灰, 经过造球制粒, 可以进入装置预热 100°C〜500°C, 经过旋转炉箅子调控处理速度, 进入等离子体弧熔融裂解区域玻璃化及其金属熔融。
