Description

一种撬装式活性炭吸附及催化燃烧结合的废气治理装置 技术领域
本发明涉及环保废气处理技术领域，具体涉及一种撬装式活性炭吸附及催化燃烧结合的废气治理装置。
 背景技术
随着经济的发展，制造加工企业生产过程中，产生有机废气越来越多，且种类繁多。目前国内外传统的治理有机废气常采用方法有：直接燃烧、催化燃烧法、吸附法、生物净化、低温等离子、光催化氧化，以上几种方法，各有千秋。目前传统的有机废气治理工艺采用活性炭吸附+催化燃烧法进行治理。
直接燃烧，适用于浓度高，气量小的可燃性气体；但设备易腐蚀，运行维护处理成本高，易形成二次污染。催化燃烧法，在催化剂的作用下，使有机废气中的碳氢化合物在温度较低的条件下迅速氧化成水和二氧化碳；但催化剂易中毒，投入成本高。生物净化法，利用微生物把废气中的污染物分解转化成少或甚至无害物质；但净化设备占地面积大，且对调节池内酸碱度有要求。低温等离子，通过产生富含极高化学活性的粒子与有机废气发生反应，转化为二氧化碳和水；但一次性投资较高，存在着一定安全隐患。光催化氧化，利用特种紫外线波段，在特种催化氧化剂的作用下，将废气分子破碎并进一步氧化还原的一重特殊处理方式；但容易产生高浓度臭氧，污染周围环境。
吸附法，利用吸附剂吸附有机废气，净化效率高，成本低。目前大多数采用吸附法进行有机废气治理，也是传统的治理方法。常采用的吸附剂是活性炭；但活性炭吸附饱和后，需进行脱附再生才能继续使用。
目前，单一的处理方法，已经不能满足环保及持续处理的要求，因此，常采用吸附法+催化燃烧结合的方式对废气进行治理，以保证废气处理装置能持续使用。对于这类废气处理装置，现在都是将各个部件、风管、阀门、风机等散件发往现场，在现场进行组装，由于现场布局经常调整变化，风管需要增加或减少，风管都是保温管，现场调整非常困难，难以保证产品质量，给现场安装带来诸多不便。
 技术问题
有鉴于此，本发明的目的是提供一种撬装式活性炭吸附及催化燃烧结合的废气治理装置，不仅能自动控制温度和脱附时间，而且能解决各个部件现场组装的难题、减少现场施工难度、提高施工质量以及加快施工进度。

进一步，所述进风管道上延伸出进风支管，所述进风支管上设置有新风阀。
进一步，所述补风冷管道通过补冷风支管与排放口连通，在补冷风支管上设置有电动风阀D。
进一步，脱附风机的出风端通过三通分别与出风管道和出风支管连通，在出风支管上设置有电动风阀F，所述脱附气管道上设置有电动风阀E。
进一步，在进风管道上设置有温度检测A，在电动风阀E与催化燃烧装置出风端之间的脱附气管道上设置有温度检测B，在出风口与电动风阀E之间的脱附气管道上设置有温度检测C。
 有益效果

 本发明的实施方式
下面通过附图和实施例对本发明进一步详细说明。通过这些说明，本发明的特点和优点将变得更为清楚明确。显然,所描述的实施例仅是本发明的一部分实施例,而不是全部的实施例。
如图1-6所示，一种撬装式活性炭吸附及催化燃烧结合的废气治理装置，包括催化燃烧单元A和活性炭吸附单元B，所述催化燃烧单元包括底座1和固定安装在底座上的设备主体。
所述设备主体包括脱附风机10、催化燃烧装置3和补冷风机14，所述脱附风机10的进风端连接有带进风口6的进风管道，所述进风管道与脱附风机10连接的一端设置有电动风阀B13，电动风阀B13用于调控进风管道的导通与否，所述进风口6通过管道与活性炭吸附单元的出风端连通。脱附风机10的出风端通过出风管道与催化燃烧装置3的进风端连通，在出风管道与催化燃烧装置3连接的一端设置有进风口阻火器2，所述催化燃烧装置3的出风端连接有带出风口19的脱附气管道，所述脱附气管道上连接有带排放口8的排放管道，所述排放管道上设置有电动风阀A7，打开电动风阀A17，可以通过排放口8将燃烧后的气体和水排放。在脱附气管道与催化燃烧装置3连接的一端设置有出风口阻火器4，所述出风口19通过管道与活性炭吸附单元的进风端连通。所述进风口阻火器2和出风口阻火器4均通过金属过滤板将燃烧过程中火星颗粒（＞1毫米）过滤，然后经管道进入下到工序，避免火灾的发生。具体工作过程中，在脱附风机10的抽送作用下，进风口把活性炭解析出来的高浓度废气送至催化燃烧装置，在催化燃烧装置内，高浓度废气进行氧化反应，变成无害的水和二氧化碳，同时产生高温脱附气体，高温脱附气体经出风口送入活性炭设备对活性炭进行高温解析脱附再生，使活性炭恢复吸附能力。
所述补冷风机14的出风端通过补冷风管道与脱附气管道连通，在补冷风管道与脱附气管道连接的一端设置有电动风阀C16，通过补冷风管道可以向脱附气管道内吹送补冷风，以便调节脱附气体的温度，关闭电动风阀C16，可以停止向脱附气管道内吹送补冷风。
所述补风冷管道通过补冷风支管与排放口连通，在补冷风支管上设置有电动风阀D17。补冷风机启动时，一部分气流流入补冷风支管，可以提高排放口8的排放能力，同时，当排放口与吸附系统主管道连通时，可以把新鲜空气送至活性炭吸附系统主管道内，防止废气沉积导致废气浓度超过爆炸下限而带来安全风险。
所述进风管道上延伸出进风支管，所述进风支管上设置有新风阀12；脱附风机的出风端通过三通11分别与出风管道和出风支管连通，在出风支管上设置有电动风阀F20，所述脱附气管道上设置有电动风阀E18。在具体工作过程中，当进风口6停止进气时，打开新风阀12，使空气从进风支管流入，同时打开电动风阀F20，并调节电动风阀E，使脱附气管道内气流换向，这样，在脱附风机作用下，空气经出风支管流入脱附气管道，可以对催化燃烧单元进行反吹清洗。优选地，在新风阀处设置阀门护网，以便防止异物进入设备管路内。
在进风管道上设置有温度检测A15，温度检测A用于检测进风温度；在电动风阀E与催化燃烧装置出风端之间的脱附气管道上设置有温度检测B5，温度检测B5用于检测排放气温度和脱附气温度；在出风口与电动风阀E之间的脱附气管道上设置有温度检测C9，温度检测C用于检测脱附气温度。
综上所述，采用废气治理装置，一方面，催化燃烧单元为一体化集成式结构，结构紧凑、功能齐全、安装便捷，减少了现场施工难度、提高了施工质量以及加快了施工进度；另一方面，实现了自动脱附、吸附等，能自动控制温度和脱附时间，保证了废气处理的效率和效果。
最后说明的是，以上实施例仅用以说明本发明的技术方案而非限制，尽管参照较佳实施例对本发明进行了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换，而不脱离本发明技术方案的宗旨和范围，其均应涵盖在本发明的权利要求范围当中。
