Description

处理内燃机尾气的催化过滤装置 技术领域
本发明一般涉及处理内燃机尾气的装置， 特别是用于处理从内燃机排出的 尾气的催化过滤装置。 背景技术
内燃机已被广泛用于各种不同的交通工具。从内燃机排出的尾气含有 CO, C02, HC和 NOx, 这些气体是导致大气污染和地球温室效应的主要因素之一。
现有技术中， 处理尾气的方法主要集中于以下两种方式。 其一为贵金属催 化转化。 这种方法需要使用贵金属如 Pt、 Pd含量较高的催化剂， 从而导致较高 的成本。 此外， 即使是最不易被氧化的贵金属 Pt, 在尾气中含有的 NOx和氧 存在的情况下， 也会被慢慢氧化， 从而使催化剂失去活性。 另一处理尾气的方 法为采用过滤装置进行过滤。 现有的过滤装置通常艮难处理有机可溶性杂质。 此外， 现有的过滤装置很难阻止尾气在约 500Ό的温度下产生硫酸盐和在更低 的温度下吸附 HC。 因此， 需要为过滤装置设置再生处理装置。
本发明为解决现有技术的缺陷， 提出了一种用于处理内燃机尾气的催化过 滤装置。 本发明概述
本发明的目的之一是提供一种在处理内燃机尾气的过程中使用的催化过 滤装置， 包括： 外壳体， 具有相对而设的第一端面和第二端面;进气口， 位于外 壳体的第一端面上； 出气口， 位于外壳体的第二端面上;第一过滤罩体， 置于外 壳体内， 其一端与第二端面连接， 另一端封闭;第二过滤罩体， 置于第一过滤罩 体内， 其一端与第二端面连接， 另一端封闭， 其内腔与第二端面上的出气口连 通。 在本发明中， 第一过滤罩体和第二过滤罩体都为滤网栅结^， 第一过滤罩 体和第二过滤罩体之间填充有颗粒催化剂 , 尾气可从所述第一过滤罩体的外部 流入到所述第二过滤罩体的内部。
在本发明的一优选实施方案中， 催化过滤装置的外壳体内壁包括一保温 层。 在另一实施方案中， 催化剂为铝珠或陶瓷片或两者的混合物， 当然铂、钯、 或钴、 或其混合物， 以及铝珠或陶瓷片与铂、 钯、 钴的混合物也可应用于本发 明中。
本发明的催化过滤装置结构筒单， 催化剂原料成本低， 但可以达到很好的 处理内燃机尾气的效果。 附图筒要说明 - 图 1是根据本发明的催化过滤装置一实施例的示意图；
图 2是图 1所示的催化过滤装置的剖视图； 本发明优选实施例的详细说明
下面结合附图对本发明进行详细说明。
图 1和图 2显示了本发明一实施例的用于处理来自内燃机的尾气的催化过 滤装置 100。 该催化过滤装置 100包括： 外壳体 1000， 具有第一端面 10和第二 端面 20。第一端面 10具有进气口 11 ,来自内燃机的尾气通过该进气口 11进入 催化过滤装置 100。 设置在外壳体 1000内的催化过滤装置 106, 一端固定在 第二端面 20上， 另一端为封闭端 1061。 封闭端 1061与进气口 11间隔一定的 距离， 优选该距离尽可能地小， 使得尾气进入催化过滤装置后能够尽快进入催 化过滤装置 106。
催化过滤装置 106包括第一过滤罩体 1064, 在第一过滤罩体 1064内固定 有第二过滤罩体 1065。第一过滤罩体 1064和第二过滤罩体 1065分别由铝和铁 磁材料制成， 可以形成为包括圆柱体形状在内的多种形状， 并优选形成为圆柱 体形状。 第二过滤罩体的内腔与第二端面 20上的出气口 21连通。 第一过滤罩 体 1064和第二过滤罩体 1065共用相同的封闭端 1061。在第一过滤罩体与第二 过滤罩体之间填充有催化剂 1062。 催化剂为铝珠或陶瓷片或两者的混合物。
另外， 在本发明的优选实施例中， 在外壳体 1000中设置有保温层 108, 以 保证本发明催化过滤装置内的催化反应能够在较高的温度下进行。 这可以通过 在外壳体 1000内充填绝热材料如粘土和石棉或其混合物来实现。
外壳体 1000在第一端面 10和第二端面 20之间的内壁可以是 A1203层 109。 使得部分尾气在该 A1203层的作用下进行初步催化反应。
因此， 尾气流经第一过滤罩体 1064, 在催化剂 1062的作用下进行催化反 应后经第二过滤罩体 1065， 进入笫二过滤罩体的内部， 然后从出气口 21排出。 这样尾气中具有较高分子量的一些物质可以被进一步分解。 第一和第二过滤罩 体可以消除在尾气中存在的任何固体颗粒。 '
本领域的技术人员应当理解， 上述实施例和说明只是对本发明的举例说 明。 在本发明的精神和实质范围内的各种修改和变形都应属于本发明的范围。
