Description

一种防疫通道及防疫方法 技术领域
本发明属于防疫技术，具体涉及一种防疫通道及防疫方法。
背景技术
2020年，全球爆发了新型冠状病毒肺炎疫情(世卫组织将其命名为COVID-19)，由于该病病毒传染力强、传播速度快，对社会生产秩序产生巨大影响，将对全球经济造成不可估量的损失。此外，由于新冠肺炎疫情的突发性和具备极强的传播能力，在某种程度上引起了一些社会恐慌，疫情防控任务艰巨。
2003年爆发的非典型肺炎疫情，中国内地累计病例5327例，死亡349人，造成中国直接经济损失达933亿元人民币。除此以外，冬季、春季是我国南方流行病、传染病高发季节，如流行性感冒、禽流感等，每年都有大量人员感染此类流行病，对生产生活造成极大影响。
疫情发生后，可在建筑入口设置防疫通道来开展疫情防控工作，目前，防疫通道主要采用一套回风循环通风净化系统在密闭通道内循环净化内部空气，再采用侧面对吹或者侧面对吹与顶部下吹组合的方式对人员表面进行吹淋净化，如果有感染人员进入通道内，回风循环后感染人员呼出的病毒可能继续存在于通道内，将会使后续进入的人员存在交叉感染风险，从而造成建筑内部的疫情扩散，存在较大的安全隐患。
因此，针对上述防疫通道存在的不足，研究一种用于防疫通道、避免交叉感染风险的防疫方法具有重要意义。
发明内容
本发明的目的之一在于提供一种防疫通道，实现杀菌消毒的同时避免交叉感染风险。
本发明的防疫通道包括一个通道本体，所述的通道本体设有进风系统、回风系统和排风系统，所述通道本体内分为上部区域和下部区域，所述进风系统包括进风口、进风机、第一过滤杀毒装置和安装于所述通道本体顶壁、上部区 域之侧壁由多个喷嘴构成的第一喷嘴组，所述进风机通过所述进风口引入外部新风，外部新风依次经所述进风口、所述进风机、所述第一过滤杀毒装置、所述第一喷嘴组喷淋净化所述通道本体的所述上部区域；所述回风系统包括回风口、回风机、第二过滤杀毒装置和安装于所述通道本体下部区域之侧壁由多个喷嘴构成的第二喷嘴组，所述通道本体内的空气依次经回风口、回风机、第二过滤杀毒装置和所述第二喷嘴组循环喷淋净化所述通道本体的下部区域；所述排风系统包括与所述通道本体两端底部设置的排风进风口、与排风进风口连通的排风管、排风机、第三过滤杀毒装置和排风出风口，所述通道本体内部排出的空气依次经所述排风进风口、所述排风管、排风机、第三过滤杀毒装置和排风出风口流向所述防疫通道外部。
本发明的防疫通道可设置于车站、机场、商场、小区等人们聚集场所的入口，对进入场所的人员进行净化消毒。人进入防疫通道后，外部新风先经进风机加压，再由第一过滤杀毒装置消毒，最后经第一喷嘴组喷射入通道本体内上部区域，其中，通道本体顶壁的喷嘴自上而下喷射外部新风，上部区域侧壁的喷嘴相对喷射外部新风，进风系统可迅速清除上部区域的病毒、细菌和尘埃，通过吹淋可对人处于上部区域的身体各部位全面消毒；回风系统用于引导通道本体内的气流方向，使通道本内体的空气经回风机加压，再由第二过滤杀毒装置消毒后，经第二喷嘴组喷射入通道本体的下部区域，下部区域侧壁的各喷嘴相对喷射气流，通过吹淋可对处于下部区域的身体各部位全面喷淋净化；排风系统用于抽离通道本体内的空气，从而和进风系统组合调控防疫通道内外的压差，抽离出的空气经第三过滤杀毒装置处理后从排风出风口排出，可避免排出空气产生的二次污染。本发明的进风系统、回风系统、排风系统同时作用，使通道本体内空气有组织有方向的流动，上部区域一直持续通入过滤杀毒处理后的外部新风，上部区域的空气持续流动至下部区域，持续的高速气流产生正压使下部区域的空气不会上流，保障人在上部区域吸入的为最新鲜的无毒空气。
本发明的防疫通道可作以下优化改进：
本发明所述通道本体的顶壁和侧壁设有中空的夹壁层，且所述夹壁层包括上层和下层，所述上层与所述下层之间隔断使空气无法相互流通，所述上层的顶部与所述进风机的出口连通，所述上层还与所述的第一喷嘴组连通，且所述 上层内设置所述的第一过滤杀毒装置；所述下层的底部与所述回风机的出口连通，所述下层还与所述的第二喷嘴组连通，且所述下层设置所述的第二过滤杀毒装置；所述上层内设置有用于连通相对侧壁上两个夹壁层之下层的风管。
本发明所述通道本体的顶部设有进风箱体，所述进风箱体的两端开设所述的进风口，所述进风机位于所述进风箱体中。
本发明所述的回风口位于所述通道本体内部的一个侧壁上，所述回风口和所述夹壁层的下层之间通过所述的回风机连通。
本发明所述通道本体的的两端底部边缘设置所述的排风箱体，所述排风箱体开设有所述的排风进风口，所述排风箱体与所述的排风管相连通，排风管连接至排风机。
本发明所述第一过滤杀毒装置、第二过滤杀毒装置和第三过滤杀毒装置为初效过滤器、高效过滤器、高压杀菌过滤器、紫外线消毒器等过滤消毒设备的一种或任意两种的组合，用于空气杀菌、消毒和净化。
本发明的目的之二在于提供一种应用上述防疫通道的防疫方法，其中，第一喷嘴组和第二喷嘴组的各喷嘴为喷射方向可调节的喷嘴，通过进风系统、回风系统和排风系统控制所述通道本体内的空气和外部空气的压力差，并且控制所述通道本体内气流流速和流向，形成上、下两个空气区域，通过进风系统的第一喷嘴组向所述通道本体内的上部区域送入经第一过滤杀毒装置处理后的外部新风，喷淋净化所述上部区域，通过回风系统的第二喷嘴组向所述通道本体的下部区域循环送入经第二过滤杀毒装置处理后的空气，喷淋净化所述下部区域，对进入所述通道本体内的人员进行喷淋消毒，并且所述第一喷嘴组持续将所述上部区域的空气吹向下部区域，保障人员吸入空气为所述上部区域经第一过滤杀毒装置处理后的外部新风。
本发明的防疫方法保障通道本体内一直为经过滤杀毒后的无毒空气，尤其上部区域供人吸入的空气持续更新为新鲜的无毒空气，避免交叉感染。
本发明所述防疫通道高度根据使用人员身高确定，当成年人使用时通道本体内部高度为1.9米，儿童使用时为1.6米，其他使用场合可根据需求调整。所述上部区域的高度≥所述通道本体内部高度的2/5，即使所述通道本体内人的腋部以上的身体部位位于所述上部区域。
综上所述，本发明具有如下优点：
(1)本发明利用进风系统、回风系统和排风系统将防疫通道内部划分为上部区域和下部区域两个空气区域，上部区域的空气气流持续向下流动，来自上部区域的气流产生的正压作用使得回风循环只发生在下部区域内，确保上部区域无呼出气体残留，上部区域为从外界引入并经过滤杀毒后的新鲜无毒空气，供人员吸入；进风系统吹淋净化上部区域，回风系统循环利用通道内的部分空气过滤杀毒后通过吹淋净化下部区域，排风系统使防疫通道内空气有组织有方向的流出。使每一个进入通道的人员呼吸区域均是经过滤杀毒处理的新风，不会发生交叉感染，实现防疫目的。
(2)本发明的排风系统将排出防疫通道的空气进行杀毒处理，避免二次污染。
