一种便携式室内甲醛检测装置A portable indoor formaldehyde detection device

技术领域technical field

本实用新型涉及室内空气质量检测技术领域，具体而言，涉及一种便携式室内甲醛检测装置。The utility model relates to the technical field of indoor air quality detection, in particular to a portable indoor formaldehyde detection device.

背景技术Background technique

人们生活水平不断提高，对于居住的要求也越来越高。目前装修材料多是胶结材料或含油漆等，这些材料多半带会释放有毒物质，如苯、甲苯、二甲苯、甲醛等。装修短时间内，苯、甲苯、二甲苯浓度较高，甲醛浓度较低；但随着时间推移，苯、甲苯、二甲苯浓度逐渐下降，甲醛的浓度呈升高趋势，这些物质会严重影响人体的健康。随着人们对于健康的重视，以及家装行业的兴起，典型污染物的检测也成为当前研究的重点之一。甲醛危害持久、后果严重的特点，所以目前市面上的检测大都是针对甲醛。甲醛分析的国家标准方法可分为分光光度法和气相色谱法两大类，但这两类方法均需先在监测现场采集气体样品，再回实验室分析，分析周期长，成本高，步骤繁琐，不能实时地反映室内空气甲醛污染的状况。如要使得测量快速且便携，则可以采用传感器测量法，目前市面上使用的家用便携式测量仪使用就是电化学传感器。With the continuous improvement of people's living standards, the requirements for living are also getting higher and higher. At present, the decoration materials are mostly cement materials or paints, etc. Most of these materials will release toxic substances, such as benzene, toluene, xylene, formaldehyde, etc. In a short period of time, the concentration of benzene, toluene and xylene is high, and the concentration of formaldehyde is low; but with the passage of time, the concentration of benzene, toluene, and xylene gradually decreases, and the concentration of formaldehyde shows an increasing trend. These substances will seriously affect the human body. of health. With people's emphasis on health and the rise of the home improvement industry, the detection of typical pollutants has also become one of the focuses of current research. Formaldehyde has the characteristics of lasting harm and serious consequences, so most of the current tests on the market are aimed at formaldehyde. The national standard methods for formaldehyde analysis can be divided into two categories: spectrophotometry and gas chromatography, but these two types of methods require gas samples to be collected at the monitoring site first, and then returned to the laboratory for analysis. The analysis cycle is long, the cost is high, and the steps are cumbersome. , can not reflect the indoor air formaldehyde pollution situation in real time. To make the measurement fast and portable, a sensor measurement method can be used, and electrochemical sensors are currently used in household portable measurement instruments on the market.

市面上普遍存有甲醛测试仪、甲苯测试仪，这些测试仪器通常都是单独分开的。以甲醛测试仪为例，目前市面上销售的甲醛测试仪多利用DART Sensor 公司的电化学传感器，但该电化学传感器输出电流只有nA 级，信号微弱，很容易受到外界的干扰，而且价格比较昂贵，很难做到低成本。同时，在测量数据时候该传感器不能有效的保存数据，不具备无线通信的方式，且布线繁杂，成本高，拓展性和移动性差。而且，对于测试数据的处理实时显示，这不能对居住空间的质量分析及判断提供有效的参考依据。鉴于以上种种不足，研制一种新的快速、连续、自动、廉价的监测仪就成了一项十分有意义的工作。Formaldehyde testers and toluene testers are widely available on the market, and these testers are usually separate. Taking the formaldehyde tester as an example, most of the formaldehyde testers on the market use the electrochemical sensor of DART Sensor, but the output current of the electrochemical sensor is only nA level, the signal is weak, it is easy to be interfered by the outside world, and the price is relatively expensive. , it is difficult to achieve low cost. At the same time, when measuring data, the sensor cannot effectively save data, does not have a wireless communication method, and has complicated wiring, high cost, and poor scalability and mobility. Moreover, for the real-time display of test data processing, this cannot provide an effective reference basis for quality analysis and judgment of living space. In view of the above shortcomings, developing a new rapid, continuous, automatic and inexpensive monitor has become a very meaningful work.
