Description

一种改进的除甲醛装置 技术领域
本实用新型涉及一种改进的除甲醛装置。
背景技术
装修污染物中甲醛对人体危害最严重，潜伏期最长，被称为“室内污染第一杀手”；被WHO世界卫生组织确定为“致癌和致畸性物质”。长期接触低剂量甲醛，能引起慢性中毒，引发呼吸系统、神经系统、生殖系统等疾病。
发明内容
本实用新型的目的在于提供一种改进的除甲醛装置。
本实用新型通过如下技术方案得以实现：
一种改进的除甲醛装置，包括反应池、进气管、排气管和风机；其中，用于存储甲醛溶解酶溶液的反应池的底部连通有更换溶液用的管道，该管道上设有阀门；所述进气管的出口端与所述反应池连通并延伸至反应池的底部，该进气管的入口端与大气连通并设有收集罩，收集罩内设有过滤网，该进气管内、于入口端与反应池之间设有第一活性炭过滤层；所述排气管的入口端与所述反应池连通，该排气管的出口端设有风机，自入口端至出口端依次设有无水硫酸铜干燥层和第二活性炭过滤层。
优选地，所述反应池的材质为聚四氟乙烯。
优选地，所述过滤网为除PM2.5高效过滤网。
本实用新型的优点：
本实用新型提供的除甲醛装置可以有效去除空气中的甲醛，结构简单，易于生产。
附图说明
图1为除甲醛装置结构示意图；其中，1为反应池，2为进气管，3为排气管，4为更换溶液用的管道，5为阀门，6为收集罩，7为第一活性炭过滤层，8为风机，9为无水硫酸铜干燥层，10为第二活性炭过滤层，11为甲醛溶解酶溶液，12为除PM2.5高效过滤网。
具体实施方式
下面结合附图和实施例具体介绍本实用新型实质性内容。
如图1所示的一种改进的除甲醛装置，包括反应池1、进气管2、排气管3和风机8；其中，用于存储甲醛溶解酶溶液11的反应池1的底部连通有更换溶液用的管道4，该管道上设有阀门5；所述进气管2的出口端与所述反应池1连通并延伸至反应池1的底部，进气管2的入口端与大气连通并设有收集罩6，收集罩内设有除PM2.5高效过滤网12，该进气管2内、 于入口端与反应池1之间设有第一活性炭过滤层7；所述排气管3的入口端与所述反应池1连通，该排气管3的出口端设有风机8，自入口端至出口端依次设有无水硫酸铜干燥层9和第二活性炭过滤层10。反应池1的材质为聚四氟乙烯。
工作原理：在反应池1中装有甲醛溶解酶溶液11，启动风机8，含有甲醛的大气经收集罩6进入进气管2，通入甲醛溶解酶溶液11中，去除甲醛的气体经排气管3排出。进气管2中的第一活性炭过滤层7可以有效滤除空气中的灰尘等杂质，减少对甲醛溶解酶溶液11的污染。除PM2.5高效过滤网12增加一次过滤，延长第一活性炭过滤层7中活性炭的使用寿命。排气管3中的无水硫酸铜干燥层9可以对气体进行干燥，避免第二活性炭过滤层10中的活性炭受潮结块。排气管3中的第二活性炭过滤层10对气体进一步吸附除杂后排向大气中。
本实用新型提供的除甲醛装置可以有效去除空气中的甲醛，结构简单，易于生产。
上述实施例的作用在于具体介绍本实用新型的实质性内容，但本领域技术人员应当知道，不应将本实用新型的保护范围局限于该具体实施例。
