Description

冷藏集装箱空气洁^殳备 技术领域 本发明涉及一种用于运输果蔬花卉的冷藏集装箱上的箱内空气洁净设 备, 属于集装箱空气洁净设备结构技术领域。 背景技术 我国是农产品生产大国, 蔬菜、 果品和花卉的总产值在我国农业总产值 中成为列在粮食之后的第二位和第三位的农村经济支柱产业。 同时花卉生产 也成为我国近年来高效农业新的增长点。 但是由于我国果蔬花卉釆收以后的保鲜储运设施落后,导致出现腐烂严 重、 品质衰败, 每年损失数以百亿计。 据调研, 其中一个重要原因是一直未 能解决果蔬花卉釆后储运期间的储藏空间内的空气洁净问题, 有害有机挥发 物特别是乙烯和病原体得不到有效清除。
20世纪 50年代初, 国际园艺界专家经深入研究确认了乙烯 ( C2H4 ) 是一种可促进园艺产品成熟衰老的极敏感生长激素, 无论是内源性乙烯, 外 源性乙烯当在储运环境中达到一定浓度时, 都会刺激釆后的果蔬花卉发生呼 吸强度增大、 叶绿素下降、 硬度下降、 加速衰老等一系列不可逆转的生理变 化, 最终导致品质下降, 提前衰败。 据研究表明, 香蕉、 菠萝、 猕猴桃、 梅、 芒果、 苹果、 梨、 桃、 黄瓜、 菜花、 番茄等许多果蔬产品都属于乙烯高敏感型, 当储运环境中的乙烯浓度 仅 0.02 P.P.M时, 即可引起 "扳机', 式后熟反应。 国际国内许多案例都证实 了由于储运环境中的乙烯含量未控制在安全极限以下, 轻者造成整库、 整集 装箱的果蔬品质劣变, 重者造成果蔬全部腐烂。 目前用于冷藏集装箱的果蔬保鲜设备主要有气调设备、安装在冷藏集装 箱内的乙烯清除设备和箱内空气自动通风换气设备。 但上述设备都有不足, 详述如下:
1. 冷藏集装箱气调设备价格高昂、 操作复杂、 对各种果蔬花卉产品的 贮藏适用性差, 对冷藏集装箱的维修、 管理和集装箱装货后的箱体密封水平 有极高的技术要求, 因此现阶段实用性很差, 在进出口果蔬保鲜储藏运输中 极少使用。
2. 安装在集装箱内使用的乙烯脱除设备, 安装复杂、 占用箱内货物的 装载空间、 需要在果蔬产品装箱前安装使用, 而且安装设备时将对箱内保温 层的结构造成损害, 在运输过程中设备如发生故障, 则无法进入集装箱维修 保养, 导致果蔬产品腐烂变质。
3. 安装在冷藏集装箱上的箱内空气自动换气设备, 是靠检测箱内二氧 化碳气体浓度进行自动换风的。 这样一是不能完全换风, 箱内仍存在损害果 蔬品质的有害气体和病原体, 对果蔬产品造成损害。 二是因换风造成箱内相 对湿度过低, 果蔬花卉因千耗失水而造成失重和千缩损失。
4. 上述设备没有杀菌功能或杀菌功能不足, 不能有效地杀灭冷藏集装 箱内空气中的病原体(细菌、 病毒、 花粉螨、 霉菌、 芽孢和真菌等)、 达到延 长果蔬花卉寿命的目的。 发明内容 本发明目的在于解决上述已有技术存在的不足之处,提供一种釆用复合 纳米二氧化钛光催化技术和独特结构设计的, 催化氧化效率高、 脱除有机混 合物 (VOC)特别是乙烯、 乙醛、 乙醇等有害气体效果好、 杀菌能力强、 结构 合理、 安装拆卸快捷、 维修方便, 能够实现自我检测、 自动控制的冷藏集装 箱空气洁净设备。 本发明的特点是将空气洁净设备安装在冷藏集装箱制冷机组蒸发器盘 管风扇维修孔处, 通过制冷机组的循环风道与集装箱内空气进行交换, 达到 清除冷藏箱内空气中的有害有机混合物 (VOC)特别是乙烯气体和病原体的目 的, 保持箱内空气洁净, 使箱内的果蔬花卉产品的储运时间延长, 品质得到 保证。 本发明是通过以下技术方案实现的: 冷藏集装箱空气洁净设备, 安装在冷藏集装箱箱体外部的制冷机组 21 蒸发器盘管风扇维修孔处, 通过制冷机组 21 的蒸发器风扇 17 , 将从进风口 19吸入箱内的空气经本洁净设备杀菌清洁后, 再经蒸发器 18、 循环风道 16 送到出风口 20 , 进行送回风循环达到制冷恒温的目的; 特殊之处在于包括由 外盖板 1和内盖板 2组成的壳体, 内盖板 2的上下两端分别设有出风口 5和 进风口 4 ,进风口 4通过制冷机组蒸发器风扇 17或设备自带的风扇 9收集来 自集装箱内的空气与进风过滤网 3连通, 壳体内设有外周带保温层 10的光 催化反应槽 7 , 槽内设多个紫外线杀菌灯管 8 , 在灯管与灯管之间的空间内 均匀填充表面涂有多层光催化剂的高硅硼玻璃载体 11 , 进风口 4与光催化反 应槽 7之间设有恒温加热板 6 , 用于对进入光催化反应槽 7的空气进行提前 加热; 壳体的外盖板 1上设有控制器, 壳体下部分别设有与灯管 8连接供电 的宽输入电压开关电源或降压变压器 12、 用于监控灯管工作时间的累时器 14 , 控制器中自动监测箱内气体浓度的监控记录模块 13的微处理器 23连接 传感器探头 24、 显示器 25、 控制电路 26; 控制电路 26控制连接带镇流器的灯管 8、 风扇 9、 累时器 14; 所述紫外线杀菌灯管 8的波长均为 254nm; 所述光催化剂釆用复合纳米二氧化钛; 当釆用制冷机组蒸发器风扇 17时, 因蒸发器风扇 17外围设挡板 22 , 挡板 22的上下产生压差形成风道, 挡板 22与壳体的内盖板 2之间设有密封 隔条 15将进风口和出风口隔开, 保证机内空气正常循环。 本发明的冷藏集装箱空气洁净设备, 釆用填埋光源式设计, 光催化剂釆 用复合纳米二氧化钛, 经过表面多层涂敷有复合纳米二氧化钛的微型玻璃载 体均匀疏松地填充在反应槽内紫外线灯管周围, 将紫外线灯管完全填埋, 这 样光程短、 光照均勾、 光照表面积大, 光催化氧化效果极好。 光催化氧化反 应槽内紫外线光源全部釆用 254nm杀菌灯管后,既与二氧化钛催化剂在紫外 线光能的激发下产生的羟基结构结合能有效地提高杀菌效果, 而灯管本身也 产生杀菌效果, 二者结合达到高效广谱杀菌、 清除空气中病原体的目的。 本设备安装在冷藏集装箱制冷机组蒸发器盘管风扇的维修安装孔上,安 装、 拆卸和维修保养异常方便, 而且不占用任何箱内空间, 果蔬花卉产品可 随时装入集装箱, 用户可根据果蔬花卉的品种和实际需要决定是否安装本设 备。 附图说明
