背景技术
在家庭、 宾馆、 写字楼、 学校、 医院、 餐厅、 KTV包间、 车站、 候机楼等等 的室内空间， 空气的洁净直接影响人们的健康， 因此需要定期地对室内环境进 行杀菌、 消毒， 以确保室内环境卫生、 清洁， 防止居住者或者公众受到有毒有 害气体或病毒等致病物质的侵害而影响身体健康或罹患疾病。 现有的室内空气 消毒方法主要有用喷雾器喷洒消毒液或者用消毒液直接对室内物品进行擦拭； 或者使用空气净化机， 通过对室内空气进行循环过滤并经紫外线或消毒液进行 生物杀灭， 而所使用的消毒液多为过氧乙酸。
二氧化氯（C 102 )是长久以来国际上公认的最新一代的广谱、 安全、 高效的 A1 级杀菌、 消毒剂， 其对一切空气和水体传播的病原微生物均有很好的杀灭效 果， 且不产生抗药性， 尤其对伤寒、 甲肝、 乙肝、 脊髓灰质炎、 大肠杆菌、 艾 滋病毒等更有良好的杀灭效果。 并且二氧化氯杀菌消毒剂是一种无毒产品， 用 其杀菌、 消毒不会对口腔粘膜、 皮肤和头发产生损伤， 其在急性毒性和遗传毒 理学上都是绝对安全的。 在多种常用消毒剂中， 在相同时间内达到同样的杀菌 率， 二氧化氯所需要的浓度是最低的。 但是由于二氧化氯是一种气体并且其水 溶液不稳定， 二氧化氯易挥发， 容易从水溶液中以气态形式挥发出来， 此外由 于二氧化氯具有极强的氧化性和易光学分解的特点， 储运困难， 因此到目前为 止其作为杀菌剂应用于室内空气消毒还是非常有限。 实际上现有技术中尚没有 一种方法可以利用二氧化氯气体筒单、 方便、 高效地对窒内空气进行杀菌、 消 毒。

化学药剂： 硫酸氢钠（NaHS04)和亚氯酸钠（NaC102)混合粉末， 其重量比为 NaHS04: NaC102为 4: 3
试验方法： 化学反应和二氧化氯气体的稀释和排放在图 1 所示意的空气消 毒机中进行。 下面是这种消毒机结构的详细描述。
参看图 1、 图 2、 图 10, 空气消毒机包括依次连接的给药单元 1、 反应单元 2和排水送风单元 3以及加水单元 4、 加气单元 5, 还包括控制单元； 给药单元 1包括依次连接的药剂存储仓 11、 药剂定量输送装置 12和药剂投放装置 13; 反 应单元 2 包括依次连接的反应容器控制机构 21及反应容器 22; 药剂投放装置 12控制药剂投放口对准所述反应容器 22; 排水送风单元 3 包括与反应容器 22 连接送风系统以及排水系统； 控制单元包括控制给药单元 1、 反应单元 2、 排水 送风单元 3、 加水单元 4和加气单元 5的中心控制部 100以及设置于给药单元 1 和反应单元 2 中的传感部。 其中药剂定量存放在药剂瓶 111 内， 由控制单元控 制药剂输送和定量投放到反应容器 22的水中，进行化学反应生成二氧化氯气体。
由图 2和图 3中可知， 药剂存储仓 11包括药剂瓶 111, 该药剂瓶 111设置 在药剂瓶搁置架 112上， 药剂定量输送装置 12包括与药剂瓶搁置架 112连接的 输送机构 121以及驱动输送机构 121的动力部 122,中心控制部 100控制动力部 122工作。 药剂按每次的使用量定量放在药剂瓶 111中， 并搁置在药剂瓶搁置架 112上， 由药剂定量输送装置 12定量输送到药剂投放口。
输送机构 121为齿轮传动机构， 药剂瓶搁置架 112为回转结构， 输送机构 121包括连接动力部 122的主动齿轮， 设置在回转式药剂瓶搁置架 112外面、 与 所述主动齿轮啮合的齿圏 （如图 3所示）。 药剂瓶搁置架 112为圓形的搁置架， 沿圓周方向设有多个药剂瓶搁置位， 中心控制部 100每次通过动力部 122的主 动齿轮与齿圏配合控制药剂瓶搁置架 112 转动一定的角度， 将装有药剂的药剂 瓶转到投放口处， 投放完后， 将空药剂瓶移位， 也可在下一次投药前将空药剂 瓶移位。
由图 3中可知， 为使药剂在投放过程中保持稳定， 药剂定量输送装置 12还 包括设置于药剂投放口附近的药剂瓶固定机构 123,该药剂瓶固定机构 123连接 输送机构 121。
由图 2和图 4中可知， 药剂投放装置 13包括药剂瓶开启机构以及控制该机 构动作的动力机构 134, 药剂瓶开启机构为曲柄滑块机构， 包括滑动臂 131以及 与其铰接的摆动臂 132, 动力机构 134为回转式动力机构， 摆动臂 132—端偏心 铰接在动力机构 134的输出盘 133上或者铰接在输出盘 133的摆杆 1331上， 滑 动臂 131的自由端设有透孔 1311。药剂投放装置 13的作用就是当药剂瓶被推到 投放口时， 由药剂投放装置 13实现药剂投放， 其作用原理是， 当药剂瓶被推到 投放口时， 由中心控制部 100控制动力机构 134的输出盘 133转动， 此时摆动 臂 132的一端也随输出盘 133运动， 由于是偏心设置的， 所以， 这种转动在摆 动臂 132的另一端反映为直线运动， 由此带动滑动臂 131 实现直线运动， 药剂 瓶 111端盖上设有翘起的拉钩， 在滑动臂 131移动到其上方的时候， 该拉钩穿 入滑动臂 131 自由端的透孔 1311中， 当滑动臂 131向回拉时， 通过该拉钩将药 剂瓶 111的盖子揭掉， 药剂可以从瓶口投放到反应单元 2的反应容器 22中。
由图 5和图 6中可知， 反应单元 2中的反应容器 22包括罐体 221, 反应容 器 22的控制机构 21为机械结构， 包括用于封闭罐体 221开口的移动封盖 211 以及控制该移动封盖 211动作的控制机构 212, 移动封盖 211包括盖体 2111以 及套在罐体 221 口部 229边上的弹性密封装置， 所述弹性密封装置包括与罐体 221口部 229相适应的环状密封圏 2112, 该环状密封圏 2112的下表面设有环形 沟槽 21121,罐体 221口部 229嵌入该沟槽 21121内； 还进一步包括与环状密封 圏 2112连接的支撑板 213,该支撑板 213与反应容器支架 23之间设有压缩弹簧 214。 反应容器控制机构 21的作用就是打开或封闭反应容器 22, 并保证其密封 性能， 当药剂要投放时， 控制机构 212控制移动封盖 211的盖体 2111移开， 打 开罐体 221的投料口， 药剂投入后， 控制机构 212再控制移动封盖 211的盖体 2111移动到罐体 221 的投料口并盖严和密封好。 环状密封圏 2112在压缩弹簧 214的作用下可以适度上下移动， 当盖体 2111盖上时， 环状密封圏 2112在压缩 弹簧 214的作用下上顶， 保证与盖体 2111之间的密切接触， 达到良好的密封效 果。 盖体 2111上还设置有电磁铁压紧装置， 当盖体 2111盖上时， 电磁铁压紧 装置动作， 将盖体 2111更好地压紧于罐体 221的口部达到更好的密封。
控制机构 212包括驱动机构 2121和传动机构 2122, 驱动机构 2121固定在 反应容器支架 23上的， 驱动机构 2121通过传动机构 2122连接移动封盖 211; 所述驱动机构 2121为驱动电机， 传动机构 2121为齿轮传动机构， 包括设置在 驱动电机输出轴上的主动齿轮以及设置在盖体 2111连接轴上的从动齿轮。
由图 5、 图 7和图 9可知， 反应容器 22还包括设置于罐体 221侧壁上的进 风口 222、 出风口 223以及进水口 224, 以及设置于罐体 221底部的出水口 225。 由于药剂投放时是粉末状的， 需要在水溶液中进行化学反应， 所需要的水通过 罐体 221侧壁上的进水口 224输送到反应容器 22中。 反应过程中送风系统送入 的稀释用空气则通过进风口 222输入， 二氧化氯和空气的混合气体则经过出风 口 223散发到周围空间中去。 反应结束后所产生的废液经由出水口 225进入排 水系统。
由图 8、 图 9中可知， 反应容器 22的罐体 221底部设置有微孔隔层 226 , 微孔隔层 226的微孔平均孔径小于 1 加气单元包括气泵和加气管 228 , 加气 管 228与罐体 221底部出水口 225共用一段管道， 其下接有三通 331 , 气泵与三 通 331的支路连接， 气泵设置在高于反应容器 22内液面的位置可以防止在气泵 不工作时水流向气泵。 气泵通过加气管 228经微孔隔层 226向反应容器内输入 压缩空气， 这样， 一方面在反应过程中， 压缩空气经由微孔隔层 226 的微孔吹 入反应液， 在反应溶液中形成大量细小气泡， 可起到良好的搅动作用， 使反应 生成的二氧化氯气体分子充分、 加速逸出和使反应充分完全； 还可防止药剂颗 粒沉淀或者反应产物结晶在微孔垫层 226表面， 影响废水的渗透。 另一方面设 置的微孔隔层在反应过程中对反应液的流出起到延緩、 阻止的作用； 反应结束 后的废液可以通过渗透穿过微孔隔层， 从出水口 225 流出。 为了保证反应所需 的温度， 提高反应速度和效果， 反应容器 22还包括设置于罐体下部外侧壁的加 热装置 227 , 按照控制单元的指令给反应容器 22进行加热。
由图 1、 图 8、 图 9中可知， 加水系统包括清水箱、 水泵以及连接到反应容 器 22进水口 224的管路。 送风系统 32包括风机 321以及连接到反应容器 22进 风口 222的进风管。 排水系统包括与三通 331下部直管连接的排水管路 33和连 接排水管路 33的废液箱， 排水管路 331上装有电动阀门。
由图 1 0中可知， 中心控制部 100为单板机或 PLC , 为可编程控制器件， 可 以根据实际需要编程控制消毒机的整个动作过程。
由图 6和图 1 0中可知， 传感部包括在反应容器支架 23上围绕盖体 21 11连 接轴设置的两个光电传感器 101 , 该两个光电传感器 101连接中心控制部 100 , 移动封盖 211的盖体 21 11边缘突设有感应片 211 3 ,感应片 211 3随盖体 2111的 转动而在上述两个光电传感器 1 01之间移动。 上述光电传感器 101主要是用于 控制盖体 21 11的转动角度， 当移动封盖 211转动到全部打开反应容器 22投料 口时， 感应片 211 3正好移动到其中一只光电传感器 101之间， 控制单元控制移 动封盖 21 1停止转动， 当移动封盖 21 1转动到完全封盖反应容器 22投料口时， 感应片正好移动到另一只光电传感器 101之间，控制单元同样控制移动封盖 211 停止。 由图 7和图 10中可知， 传感部还包括设置于反应容器 22 内的液位传感器 102, 该液位传感器 102连接所述中心控制部 100, 液位传感器 102为一对石墨 棒电极棒或碳纤电极棒， 反应容器 22的进水口 222对准所述电极棒。 液位传感 器 102是用于测量反应容器 22中的水位高低， 采用石墨电极或碳纤电极有很好 的防腐效果， 由于反应过程中， 会产生结晶吸附在电极上， 所以， 当反应完成 后， 用水沖洗电极棒， 保证测量的精密度和灵敏度并可长期使用不失效。
由图 8和图 10中可知， 为了控制反应容器 22中的温度， 传感器部还包括 设置于反应容器 22的温度传感器 103, 该温度传感器 103连接中心控制部 100。
由图 2和图 10中可知， 传感器部还包括设置于药剂投放口附近的位置传感 器 104, 该位置传感器 104连接中心控制部 100。 当药剂被送到投放口的时候， 该位置传感器 104向中心控制部 100发出信号， 输送机构 121就停止工作， 药 剂投放装置 13和反应容器控制机构 21开始工作。
试验时， 启动消毒机， 控制单元自动控制向反应容器 22加水 50ml, 加热至 水温度达到 32°C时， 给药单元 2动作， 向反应容器 22投一支化学药剂（8.6g), 然后送风风机 321开启向反应容器 22的进风口 222送风、 气泵通过加气管 228 从反应容器 22的底部通入压缩空气通过微孔隔层 226后对反应液鼓出大量微小 气泡， 保持 32 °C温度下进行化学反应， 检测出风口 223二氧化氯（C102) 的浓 度为 17~20ppm。 开机工作 30min后， 消毒空间 C102的浓度为 7 ~ 8ppm, 对白色 葡萄球菌的杀灭率为 100%、 自然菌的消亡率为 94.35 %、 大肠杆菌的杀灭率为 99.99 %、 金黄色葡萄球菌杀灭率为 99.99 %、 鼠伤寒沙门氏菌为 99.9 %。
