Description
技术领域
本发明涉及环保设备领域,尤其涉及净化一体设备及净化一体系统。
背景技术
目前处理有机废气的方法种类繁多,特点各异,因此相应采用的治理方法也各不相同,常用的有吸收法、直接燃烧法、催化燃烧法、吸附法等。
1.吸收法
吸收法可分为化学吸收和物理吸收,大部分有机废气不宜采用化学吸收。物理吸收要求吸收剂应具有与吸收组分有较高的亲和力,低挥发性,吸收液饱和后经解析或精馏后重新使用。本法适合于中高浓度的废气,但要选择一种廉价高效的低挥发性吸收液也比较困难,同时二次污染问题较难解决,净化效果不理想。
2.直接燃烧法
本法亦称为热氧化法、热力燃烧法,是利用燃气或燃油等辅助燃料燃烧放出的热量将混合气体加热到一定温度(700~800℃),驻留一定的时间(0.3~0.5 秒),使可燃的有害物质进行高温分解变为无害物质。
本法的特点:工艺简单、适用高浓度废气治理;对于自身不能燃烧的中低浓度尾气,通常需助燃剂或加热,能耗大(运行成本比催化燃烧法高10倍以上);运行技术要求高,不易控制与掌握。此法在国内基本上未获推广,仅有少数厂家引进国外治理设备应用于较高浓度和温度的制罐印铁业废气治理中,但终因能耗大及运行不稳定,难以正常运转。
3.催化燃烧法
该法是将废气加热到200~300℃经过催化床燃烧,达到净化目的。其优点是能耗低、净化率高、无二次污染、工艺简单操作方便。可燃物在催化剂作用下燃烧,与直接燃烧相比,催化燃烧温度较低,燃烧比较完全。适用于高温高浓度的有机废气治理,不适用于低浓度、大风量的有机废气治理。
4.吸附法
(1)直接活性炭吸附法
有机废气通过活性炭的吸附,可达到90%以上的净化率,设备简单、投资小。该法不能对吸附饱和的活性炭进行再生,要求经常更换活性炭以保证净化效果,导致装卸、运输等过程中造成二次污染。

具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述。
如图1所示,本发明提出了一种净化一体设备,包括塔体1,所述塔体1下部设有第一进气口2,顶部设有第一出气口3;所述塔体1内自下向上依次设有第一喷淋管4、超级离心层5,所述超级离心层5包括支撑板6,所述支撑板6 上设有若干离心分离盘,所述离心分离盘包括中心块7,所述中心块7两侧设有过滤网,所述中心块7上连接有支撑杆8,其中超级离心层5,安装于电机上,并2300转/分钟高速旋转时,形成物理屏蔽,可将废气大量的油脂、尘埃、水蒸气、纤维等固相、液相物质拦截并通过离心原理分离出来,气体能很轻松的穿过细小的钢丝9拍出去。
其中,所述过滤网上连接有环形加强筋10,所述过滤网为圆盘形结构,所述圆盘结构上设有以中心块7为中心发散设置的钢丝9,钢丝9本身较细,强度较低,所以设置了环形加强筋10加固,同时使用支撑杆8连接中心块7进行支撑。
一种净化一体系统,包括上述的净化一体设备11、旋流塔12、过滤光解装置13、风机14和排气筒15,所述过滤光解装置13包括外壳16,所述外壳16 两端分别设有第二进气口17和第二出气口18,所述外壳16内设有初效过滤层 19和光解层20,初效过滤器适用于空调系统的初级过滤,主要用于过滤5μm以上尘埃粒子,初效过滤器有板式、折叠式、袋式三种样式,外框21材料有纸框、铝框、镀锌铁框,过滤材料有无纺布、尼龙网23、活性炭滤材24、金属孔网等,防护网有双面喷塑铁丝网和双面镀锌铁丝网,这里设计一层初效的主要原因就是防止离心失效了,在没有察觉的突发状况下,初效就可以发挥过滤作用,当离心做作用是,初效并不起作用。设计初效层就是起到一个双重保险的作用。
其中,所述光解层20包括UV紫外线灯,所述UV紫外线灯之间设有活性纳米氧化钛层,工业废气利用排风设备输入到高效光解氧化处理模块后,净化设备运用高能UV紫外线光束及臭氧对废气进行协同分解氧化反应,使废气中的恶臭气体物质降解转化成低分子化合物、水和二氧化碳,再通过排风管道排出室外。具体而言,高效光解氧化处理模块利用高能UV紫外线光束分解空气中的氧分子产生游离氧,即活性氧,因游离氧所携正负电子不平衡所以需与氧分子结合,进而产生臭氧。臭氧对有机物具有极强的氧化作用,对恶臭气体及其它刺激性异味有立竿见影的清除效果。
高效光解氧化处理模块利用高能高臭氧UV紫外线光束照射恶臭气体,裂解恶臭气体中氨、三甲胺、硫化氢、甲硫氢、甲硫醇、甲硫醚、二甲二硫、二硫化碳和苯乙烯,硫化物H2S、VOC类,苯、甲苯、二甲苯的分子键,使呈游离状态的污染物分子与臭氧氧化结合成小分子无害或低害的化合物,如CO2、H2O等。
高效光解氧化处理模块利用高能UV紫外线光束裂解恶臭气体中细菌分子键,破坏细菌的核酸(DNA),再通过臭氧进行氧化反应,彻底达到脱臭及杀灭细菌的目的,光催化主要成分为超级高活性纳米氧化钛,无机纳米材料,无毒无害,纯天然矿物改性,锐钛矿型纳米晶体,可迅速地吸附并分解甲醛、苯、甲苯、氨、 TVOC等有害气体。其主要性能为粒径超级小、分散性能好、催化活性高、性价比高。
优选的,所述风机14连接于所述第二出气口18,所述风机14上连接有所述排气筒15,所述排气筒15高20m。
优选的,所述旋流塔12包括机壳25、水泵26,所述水泵26上连接有至少两根第二喷淋管27,所述第二喷淋管27位于所述外壳16内;所述外壳16底部设有旋流电机28,所述旋流电机28上连接有若干旋流叶片30,所述旋流叶片 30成锥形设置,且锥形底部设有盲板31,所述旋流叶片30边缘设有导流槽,相邻的旋流叶片30的导流槽之间设有导流管29,塔板叶片如固定的风车叶片,气流通过叶片时产生旋转和离心运动,吸收液通过中间盲板31均匀分配到个叶片,形成薄液层,与旋转向上的气流形成旋转和离心的效果,喷成细小液滴,甩向塔壁后。液滴受重力作用集流到集液槽,并通过降液管流到下一塔板的盲板31区。具有一定风压、风速的待处理气流从塔的底部进,上部出。吸收液从塔的上部进,下部出。气流与吸收液在塔内作相对运动,并在旋流塔12板的结构部位形成很大表面积的水膜,从而大大提高了吸收作用。每一层的吸收液经旋流离心作用掉入边缘的收集槽,再经导流管29进入下一层塔板,进行下一层的吸收作用。
旋流喷淋塔的用水由水泵26从水箱中抽取,并经过滤后循环使用。多次循环后的污水,经简单处理后即可循环再使用。
对实施例的多种修改对本领域的专业技术人员来说将是显而易见的,本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下,在其它实施例中实现。因此,本发明将不会被限制于本文所示的这些实施例,而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
