Description

一种自循环新型冠状病毒空气净化方法及装置 技术领域
本发明属于空气净化设备技术领域，尤其涉及一种自循环新型冠状病毒空气净化方法及装置。
背景技术
根据最新的新型冠状病毒肺炎诊疗方案(第6版)，新型冠状病毒传染途径之一是：可以在公共空间内经过气溶胶或飞沫方式进行人际传染。对于公共空间的卫生防疫是当前高度重视的环节，目前常规的技术措施包括佩戴口罩，喷洒消毒水，采用紫外线灯杀菌，这些技术措施主要缺点在于：(1)佩戴口罩只能防止飞沫传播，常规的口罩质量难以防止病毒的气溶胶感染途径；(2)喷洒消毒药剂主要缺陷在于难以持续喷洒，消毒效果短；会引起空间异味，对空气造成二次污染，刺激人的呼吸系统引起不适；对周边的生态环境存在潜在污染；(3)采用紫外线灯进行消毒，这种方式一般在专用护理病房使用，紫外线灯的照射虽然具有杀菌效果，但是也对人的皮肤具有副作用，损害人体健康。目前市面上其它常用的空气净化器主要作用是净化空气中的颗粒物，有的型号净化器具有一定杀菌功能，但是对于新型冠状病毒杀灭效果不理想。
发明内容
为解决现有技术存在的难以防止新型冠状病毒在公共空间内经 过气溶胶途径进行人际传染的问题，本发明提供一种自循环新型冠状病毒空气净化方法及装置，有效克服常规技术和设备的缺点，能在医院、车站、电梯间、轮船、火车、商场等公共空间对新型冠状病毒进行有效杀灭，同时对周围的环境不产生二次污染，使用方便快捷，效率高，从而为医院提供更加安全的医疗环境，减少病毒感染医护人员几率，为方舱医院提供更加安全的隔离环境，减少病患交叉感染机会，为其它公共空间的人员提供安全的空气环境，减少病毒通过空气气溶胶感染扩散的机会。
为解决上述技术问题，本发明所采用的技术方案如下，一种自循环新型冠状病毒空气净化方法，其特征在于：包括如下步骤：
S1：外部空间的空气通入加热消毒单元，所述加热消毒单元对通入的空气进行高温水浴；
S2：空气由所述加热消毒单元的出风口通入氯化消毒单元，空气由下至上与所述氯化消毒单元的次氯酸钠溶液接触；
S3：空气由所述氯化消毒单元的出风口通入紫外消毒单元，空气与所述紫外消毒单元的紫外线灯充分接触；
S4：经过所述紫外消毒单元消毒的空气送入外部空间中。
作为优选，由风机将外部空间的空气通入所述加热消毒单元；可根据外部空间的高度调节所述风机的进风口高度。以便抽吸到不同高度的空气进行灭菌消毒，以及可对空气流通路径进行优化计算，保障空气流动过程中能耗最小，与加热消毒单元接触充分。
作为优选，空气通过回廊式风道结构上下回旋与所述紫外消毒单 元的紫外线灯充分接触。通过回廊式风道结构保证空气上下回旋和紫外线灯充分接触消毒。
进一步地，所述加热消毒单元高温水浴的温度范围为56℃～100℃；所述次氯酸钠溶液的浓度范围为30ppm～50ppm。在56℃下30min内新型冠状病毒可以灭活，提高温度新型冠状病毒灭活时间可以进一步缩短，高温水浴的温度根据消毒时间和风机的风量确定，消毒时间短，则需要高温水浴的温度高，风机的风量大，则需要高温水浴的温度高；一般的常规新型冠状病毒消毒采用30ppm的次氯酸钠溶液，如果外部空间受病毒污染严重，可提升次氯酸钠溶液浓度，有助于短时间内高效杀灭新型冠状病毒。
进一步地，所述加热消毒单元高温水浴的温度为80℃；所述次氯酸钠溶液的浓度为30ppm。
一种自循环新型冠状病毒空气净化装置，包括依次设置的加热消毒单元、氯化消毒单元和紫外消毒单元；
所述加热消毒单元包括加热壳体、加热盘管和加热件，所述加热壳体内设置有加热液体，所述加热盘管和加热件均设置在加热液体内，所述加热盘管通过风机与外部空间连通；
所述氯化消毒单元包括氯化壳体和氯化管路，所述氯化壳体内设置有次氯酸钠溶液，所述氯化管路上开设有若干喷口，所述喷口设置在氯化壳体内的底部，所述氯化管路通过止回阀与加热盘管连通；
所述紫外消毒单元包括紫外壳体和若干紫外线灯，若干所述紫外线灯依次间隔设置在紫外壳体内的顶部，所述氯化壳体的出风口与紫 外壳体连通，所述紫外壳体的出风口与外部空间连通。
作为优选，所述紫外壳体内设置有回廊式风道结构；所述回廊式风道结构包括若干回旋隔板，所述回旋隔板分别设置在相邻两个紫外线灯之间，且相邻所述回旋隔板，其中一个所述回旋隔板的顶端与紫外壳体的上部之间具有间隙，另一个所述回旋隔板的底端与紫外壳体的下部之间具有间隙。通过回廊式风道结构保证空气上下回旋和紫外线灯充分接触消毒，回廊式风道结构简单可靠，提高紫外线灯的消毒效率，降低成本。
作为优选，该空气净化装置还包括电机、丝杠导轨、滑块、电机驱动器和控制系统，所述控制系统、电机驱动器和电机依次电连接，所述电机的输出端与丝杠导轨传动连接，所述滑块上下滑动设置在丝杠导轨上，所述风机的进风口通过连接风管与滑块固定连接。风机的进风口高度根据外部空间的高度可以调整，以便抽吸到不同高度的空气进行灭菌消毒，以及可对空气流通路径进行优化计算，保障空气流动过程中能耗最小，与加热消毒单元接触充分。
进一步地，所述加热消毒单元、氯化消毒单元、紫外消毒单元和风机集成设置在框架上，所述框架可移动设置。框架可通过人工拖拽移动或者电控自动移动，以满足在公共空间内运行地点根据需要随时变迁。
进一步地，所述加热件选用加热丝；所述加热液体选用水；所述喷口的直径为5mm。加热丝便于随时控制水的加热温度，结构简单，成本较低；若干直径为5mm的喷口设置在氯化壳体内的底部，便于 待消毒的空气从喷口送入次氯酸钠溶液中，并由下至上和次氯酸钠溶液充分接触消毒。
有益效果：
(1)本发明的自循环新型冠状病毒空气净化装置，相比传统的空气净化设备，该空气净化装置的加热消毒单元、氯化消毒单元和紫外消毒单元三重联合消毒，持续有效杀灭空气中以气溶胶形式存在的新型冠状病毒，对新型冠状病毒的杀灭效果显著，减少人群的交叉感染；
(2)本发明的自循环新型冠状病毒空气净化装置，因空气通入次氯酸钠溶液中，而不是传统的消毒药剂直接喷洒到空气中，次氯酸钠溶液不会直接溶解在空气中，具体地，因空气经加热消毒单元的高温水浴后，加热的空气再通入氯化消毒单元的次氯酸钠溶液中，空气中携带的新型冠状病毒受到溶液中的次氯酸钠氯化作用活性降低，同时空气中的部分热量传递到次氯酸钠溶液中，次氯酸钠受热分解，根据化学反应式NaClO→NaCl+O 2，次氯酸钠受热分解为氯化钠(食盐主要成分)和氧气，不会产生异味，同时增加了空气中氧气含量；以及氯化消毒单元的出风口设置在氯化壳体的顶部，出风收集的是次氯酸钠溶液顶部空间的空气，由于重力作用离次氯酸钠溶液液面较近的不被收集，湿度高的空气存在少部分次氯酸钠溶液，确保氯化消毒单元的出风中不存在次氯酸钠溶液的异味；以及空气通过回廊式风道结构上下回旋与紫外线灯充分接触消毒，即使空气中存在极少部分的次氯酸钠微小气溶胶，在紫外线灯照射下也会分解成氯化钠和氧气，进一 步确保不会产生对人体呼吸道刺激的次氯酸，因此最终的出风空气质量安全性得到保障，持续灭杀病毒的效果更加显著，空间异味感更小，对人体身体健康造成的潜在风险更小；
(3)本发明的自循环新型冠状病毒空气净化装置，空气经加热消毒单元的高温水浴加热灭菌后，加热的空气再通入氯化消毒单元的次氯酸钠溶液中，空气中携带的新型冠状病毒受到溶液中的次氯酸钠氯化作用活性降低，且空气与次氯酸钠溶液热量传递，空气湿度受次氯酸钠溶液作用也会增加，空气再经紫外消毒单元的回廊式风道结构上下回旋与紫外线灯充分接触，空气的温湿度进一步得到调节，有益人体身体健康，相比传统空调设备，该空气净化装置同时具备对于新型冠状病毒的杀灭效果；另外由于室内空间存在空气流动的死角，局部空间的空气存在病毒污染风险，该空气净化装置的风机的进风口高度可上下调节，以及可通过拖拽该空气净化装置在待消毒的外部空间移动，能有效消除公共空间内消毒死角，消毒更加彻底安全。

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，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本发明及其应用或使用的任何限制。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
实施例1
如图1和图2所示，一种自循环新型冠状病毒空气净化装置，如图1所示，包括依次设置的加热消毒单元1、氯化消毒单元2和紫外消毒单元3；所述加热消毒单元1包括加热壳体11、加热盘管12和加热件13，所述加热壳体11内设置有加热液体，本实施例的所述加热液体选用水，所述加热盘管12和加热件13均设置在加热液体内， 本实施例的所述加热件13选用加热丝，所述加热盘管12通过风机4与外部空间连通；所述氯化消毒单元2包括氯化壳体21和氯化管路22，所述氯化壳体21内设置有次氯酸钠溶液，所述氯化管路22上开设有若干喷口221，所述喷口221设置在氯化壳体21内的底部，本实施例的所述喷口221的直径为5mm，所述氯化管路22通过止回阀23与加热盘管12连通，有效防止次氯酸钠溶液倒流至加热盘管12；所述紫外消毒单元3包括紫外壳体31和若干紫外线灯32，若干所述紫外线灯32依次间隔设置在紫外壳体31内的顶部，位于所述氯化壳体21顶部的出风口与紫外壳体31连通，所述紫外壳体31的出风口与外部空间连通；为了保证空气上下回旋和紫外线灯32充分接触消毒，在本实施例中，所述紫外壳体31内设置有回廊式风道结构33，所述回廊式风道结构33包括若干回旋隔板331，所述回旋隔板331分别设置在相邻两个紫外线灯32之间，且相邻所述回旋隔板331，其中一个所述回旋隔板331的顶端与紫外壳体31的上部之间具有间隙，另一个所述回旋隔板331的底端与紫外壳体31的下部之间具有间隙。
如图2所示，该空气净化装置还包括电机51、丝杠导轨52、滑块53、电机驱动器54和控制系统55，所述控制系统55、电机驱动器54和电机51依次电连接，所述电机51的输出端与丝杠导轨52传动连接，所述滑块53上下滑动设置在丝杠导轨52上，所述风机的进风口41通过连接风管42与滑块53固定连接，便于风机的进风口41高度根据外部空间的高度进行调整，以便抽吸到不同高度的空气 进行灭菌消毒，以及可对空气流通路径进行优化计算，保障空气流动过程中能耗最小，与加热消毒单元1接触充分。
为了该空气净化装置可便携移动，满足在公共空间内运行地点根据需要随时变迁，所述加热消毒单元1、氯化消毒单元2、紫外消毒单元3和风机4集成设置在框架上，所述框架可移动设置(图中未示意出)，。
如图1和图2所示，一种自循环新型冠状病毒空气净化方法，包括如下步骤：
S0：根据外部空间的高度调节风机的进风口41高度，具体地，当用户设定进风口高度后，控制系统55发出指令给电机驱动器54，电机驱动器54驱动电机51旋转，电机51驱动滑块53沿丝杠导轨52上下移动，滑块53带动进风口沿丝杠导轨52上下移动调整高度；
S1：风机4将外部空间的空气通入加热消毒单元1的加热盘管12中，同时加热件13加热水，对通入加热盘管12的空气进行高温水浴加热灭菌；
S2：空气由加热盘管12的出风口通入氯化消毒单元2的氯化管路22中，空气再通过喷口221喷出，并由下至上与次氯酸钠溶液充分接触进一步灭活消毒；
S3：空气由氯化壳体21顶部的出风口通入紫外消毒单元3的紫外壳体31内，空气与紫外线灯32充分接触消毒，具体地，空气通过回廊式风道结构33上下回旋与紫外线灯32充分接触消毒；
S4：经过紫外消毒单元3消毒的空气由紫外壳体31的出风口送 入外部空间中；
S5：根据待消毒的外部空间，可通过拖拽该空气净化装置在待消毒的外部空间移动。
在步骤S2中，加热消毒单元1高温水浴的温度范围可为56℃～100℃，本实施例的加热消毒单元1高温水浴的温度为80℃，具体地，在56℃下30min内新型冠状病毒可以灭活，提高温度新型冠状病毒灭活时间可以进一步缩短，高温水浴的温度根据消毒时间和风机4的风量确定，消毒时间短，则高温水浴的温度高，风机4的风量大，则高温水浴的温度高。
在步骤S3中，次氯酸钠溶液的浓度范围可为30ppm～50ppm，本实施例的次氯酸钠溶液的浓度为30ppm，具体地，一般的常规新型冠状病毒消毒采用30ppm的次氯酸钠溶液可杀灭新型冠状病毒，如果受病毒污染严重的空间，次氯酸钠溶液浓度提升，有助于短时间内高效杀灭新型冠状病毒。
该空气净化方法及装置不引起外部空间异味和二次污染，还能调节空气的温湿度，因空气通入次氯酸钠溶液中，而不是传统的消毒药剂直接喷洒到空气中，次氯酸钠溶液不会直接溶解在空气中，具体地，因空气经加热消毒单元1的高温水浴加热灭菌后，加热的空气再通入氯化消毒单元2的次氯酸钠溶液中，空气中携带的新型冠状病毒受到溶液中的次氯酸钠氯化作用活性降低，同时空气中的部分热量传递到次氯酸钠溶液中，空气湿度受次氯酸钠溶液作用也会增加，而次氯酸钠受热分解，根据化学反应式NaClO→NaCl+O 2，次氯酸钠受热分解 为氯化钠(食盐主要成分)和氧气，不会产生异味，同时增加了空气中氧气含量；以及本实施例的氯化消毒单元2的出风口设置在氯化壳体21的顶部，出风收集的是次氯酸钠溶液顶部空间的空气，由于重力作用离次氯酸钠溶液液面较近的不被收集，湿度高的空气存在少部分次氯酸钠溶液，确保氯化消毒单元2的出风中不存在次氯酸钠溶液的异味；以及空气通过回廊式风道结构33上下回旋与紫外线灯32充分接触消毒，空气的温湿度进一步得到调节，即使空气中存在极少部分的次氯酸钠微小气溶胶，在紫外线灯32照射下也会分解成氯化钠和氧气，进一步确保不会产生对人体呼吸道刺激的次氯酸，因此最终的出风空气质量安全性得到保障。
以上，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，根据本发明的技术方案及其发明构思加以等同替换或改变，都应涵盖在本发明的保护范围之内。
