Description
技术领域
本发明大体上涉及流体处理领域,且主要涉及用于处理气体的方法和装置。更具体地,本发明涉及用于处理含化学和/或生物污染物的呼吸气体例如空气的方法、装置和制品。
背景技术
由于近来恐怖主义的增多,世界各国政府已经变得越来越关注化学战剂、生物制剂、工业化学品及其它高毒性物质的影响。由于各国储备用于工业应用和作为战剂两者的这样的物质,因而,通过直接暴露和通过环境污染,这样的生物和化学污染物表现出对武装部队和平民等的潜在危险。
通常已知的化学战剂包括基于有机硫的化合物例如2,2′-二氯二乙硫醚(HD、芥子、芥子气、S芥子气或硫芥子气),它们被称为“糜烂性”或“疱肿性”毒剂且大剂量时可致死。其它化学战剂包括基于有机磷(“OP”)的化合物例如甲基硫代膦酸O-乙基S-(2-二异丙氨基)乙酯(VX)、甲基氟代膦酸2-丙酯(GB或沙林)和甲基氟代膦酸3,3′-二甲基-2-丁酯(GD或索曼),它们通常被称为“神经”毒剂,由于它们攻击中枢神经系统,且它们可在短时间内导致麻痹以及可能导致死亡。其它化学污染物包括一些工业化学品、杀虫剂和农药例如对硫磷、对氧磷和马拉硫磷,它们也可具有有害的影响。
用于对暴露于化学战剂的表面进行净化的方法和材料是本领域已知的。Yang等人的“Decontamination of Chemical Warfare Agents”,Chem Rev.Vol.92,第1729-1743页(1992)。这些净化剂溶液和材料趋于通过与所述毒剂化学反应和/或吸附所述毒剂而起作用。早期的基于化学的净化剂包括漂白粉、高锰酸钾、过氯化漂白剂、以及含有碱金属盐如碳酸钠、氢氧化钠和氢氧化钾的溶液。这些净化剂合成物中的许多趋于具有一些不期望的性质,包括腐蚀性、可燃性和毒性。另外,当暴露于水和二氧化碳时,一些基于化学的净化剂降解,这要求在与其使用的同时制备和应用溶液。
迄今为止的许多有关生物和化学药剂的研究集中在对已暴露于所述药剂的表面进行净化的立即需要。因此,虽然已经设计了用于对运载工具、设备、人员等进行净化的方法和合成物,但它们在对空气或其它呼吸气体中的生物和化学污染物进行去除、失活或解毒方面不是非常适合或有效的。
用于控制空气质量的基本方法已包括物理过滤、在固体吸附剂例如活性炭上的吸收、静电沉积、化学转化例如通过使用臭氧、以及用各种形式的辐射的处理,所述辐射包括热、紫外线和微波。过滤方法趋于受过滤器的孔径大小的限制,且通常不能去除许多种生物和化学污染物。而且,对于许多应用,超小的孔径大小以及由过滤器上的颗粒引起的堵塞可导致跨越过滤器的无法接受的压力降。粒子的静电沉积通过如下工作:使粒子带电,然后将它们从气流中移出到带相反电荷的表面例如收集板上。该技术不适于高速气流、含有挥发性化学污染物的流体或其它难以带电的污染物。化学反应,例如通过使用臭氧的化学反应,典型地仅对小体积的气体有效,且对于许多应用来说是不实用的。虽然加热对于从气体中去除许多种生物和化学污染物是有效的,但加热对于较高速度的气流趋于是无效的。紫外光也是有效的,但对于在较大的气体体积上执行可为困难的,因为所述光趋于仅对气流中紧靠光源的部分中的那些污染物有效。
通过吸附剂的气体吸附在吸附剂与气体是特定匹配时可为有效的。例如,活性炭要求炭粒子的特性与待吸附的气体的性质匹配。然而,所需要的是能够从各种气体中吸附不同组的生物和化学污染物例如细菌、病毒、神经毒剂、糜烂性毒剂、农药、杀虫剂及其它高毒性的化学药剂的固体吸附剂,所述固体吸附剂可容易地结合到各种气体处理装置中。

在一些应用中,水溶性的玻璃如美国专利No.5,330,770、6,143,318和6,881,766中所述的那些可为适当的聚合物粘结剂。在此将所提及的文献中的这样的玻璃的描述引入作为参考。在另外的应用中,还可使用通过流体吸收而溶胀的材料,该材料包括但不限于聚合物例如合成制得的聚丙烯酸和聚丙烯酰胺以及天然存在的有机聚合物例如纤维素衍生物。能生物降解的聚合物例如聚乙二醇、聚乳酸、聚乙烯醇、共聚丙交酯乙交酯等也可用作聚合物粘结剂。

此外,可将所述聚集体合成物引入过滤器基底中或涂覆到过滤器基底上。合适的过滤器基底可由所述粘结剂和基底材料例如烧结陶瓷、烧结金属、微孔碳、玻璃纤维和玻璃珠、以及纤维素纤维如棉、纸和木材形成。基底结构将取决于应用而变化,但可包括多孔膜、过滤料或其它流体渗透性结构形式的织物和无纺物。基底还可包括具有所需形状和外形尺寸的多孔且流体渗透性的固体。这样的基底可包括网状物、筛子、管、蜂窝状结构、整体料、以及包括圆筒形和环形的各种形状的块状体。

在接触所述气体之后,所述聚集体合成物可含有化学污染物以及活性的和失活的生物污染物两者。因此,在重新使用或处理之前,对所述合成物进行杀菌可为有利的。此外,在初始使用之前对该合成物进行杀菌以去除任何在使用前可存在的生物污染物可为期望的。杀菌方法可包括:热处理,其中所述合成物暴露于升高的温度或升高的压力或两者;辐射杀菌,其中使用紫外线、红外线、微波和电离辐射使所述合成物经受提高的辐射水平;以及化学杀菌,其中所述聚集体合成物暴露于提高水平的氧化剂、还原剂或其它化学物质。更具体地,可用于化学杀菌的化学物质可包括卤素、反应性氧物质、甲醛、表面活性剂、金属以及气体例如环氧乙烷、溴化甲烷、β-丙内酯和环氧丙烷。还可使用这些方法的组合,且应进一步认识到,在所述合成物处于使用中的同时可间歇或连续地运用这样的杀菌方法。
所述方法可任选地包括检测已接触所述聚集体合成物且污染物贫化的气体以测定或计算何时更换该合成物合适的步骤。检测气体可通过常规手段实现,例如标记和检测气体中的污染物,测量流速、温度、压力,检测细粒的存在,以及取样和进行化验(array)。
