Description

Technical Field

[0001] The invention belongs to the technical field of air pollutant detection, and in particular relates to a fast and accurate air pollutant purification detection system. Background Art

[0002] Indoor air pollutants refer to harmful gases, particulate matter, biological factors, etc. that exist in the indoor environment and have adverse effects on human health. There are many types of indoor air pollutants, and their effects on human health are also different. There are five main indoor air pollutants that need to be focused on, namely formaldehyde, ammonia, radon, benzene and total volatile organic compounds (TVOC). Formaldehyde and some total volatile organic compounds are easily soluble in water, and volatilize faster under high temperature conditions. Therefore, the temperature and humidity conditions of the environment are crucial for the detection of indoor pollutants. Ensuring the accuracy and effectiveness of indoor pollutant detection is crucial to protecting people's health. If the detection work is not implemented in practice, it will threaten people's lives. However, in the process of implementing the detection work, many problems are reflected, such as insufficient accuracy of detection equipment, improper operation of equipment, low professional quality of personnel, unreasonable detection methods and other factors that directly affect the accuracy of detection. Therefore, it is necessary to adopt reasonable detection methods to ensure that the corresponding detection work highlights specific results.

[0003] The detection methods of indoor pollutants can be divided into the following categories: (1) Animal and plant detection methods, which judge the degree of indoor pollution by the reaction of animals and plants in the detection environment. For example, animals may lose activity, become sick or even die, and plants may shed leaves, turn green leaves yellow or wither. This detection method cannot determine the type of pollutant, and it is difficult to perform data analysis on the concentration. (2) Physical and chemical detection methods, which mainly include spectrophotometry, gas chromatography, pump-assisted electrostatic collection energy spectrum analysis, etc., are detected through professional experimental instruments and methods. This detection method is the most precise, but at present, it is also the most time-consuming and economically expensive. (3) On-site detection of detection instruments. With the advancement of technology, many small and portable pollutant sensors are now available on the market. They can monitor the concentration of indoor pollutants in real time, providing convenience for home users. However, the detection cycle of most equipment is relatively long, and it is impossible to perform data detection on the purification efficiency of materials in different physical states. In addition, few equipment can simultaneously monitor the temperature and humidity of the environment. Summary of the invention

[0034] Each standardized test box 1 is provided with a low-position interface 3 with a valve at the lower part of the left side wall, and a high-position interface 4 with a valve at the upper part of the right side wall, and the valves of the low-position interface 3 and the high-position interface 4 are both located outside the standardized test box 1. The air guide tube 2 is a transparent silicone tube, and the two air guide tubes 2 are respectively located on the left and right sides of the standardized test box 1, one end of the air guide tube 2 on the left side is fixedly connected to the air outlet end of the low-position interface 3 on the rear side, and the other end thereof is detachably fixedly communicated with the air inlet end of the low-position interface 3 on the front side, and one end of the air guide tube 2 on the right side is fixedly connected to the air inlet end of the high-position interface 4 on the rear side, and the other end thereof is detachably fixedly communicated with the air outlet end of the high-position interface 4 on the front side.

[0035] In one embodiment, for the above detection device, the detection device includes a pollutant data collector 7 and a temperature and humidity data collector 8. The pollutant data collector 7 and the temperature and humidity data collector 8 are both fixed on the front side wall of the standardized detection box 1 in an embedded manner. The probes of the pollutant data collector 7 and the temperature and humidity data collector 8 are located on the inner side of the standardized detection box 1. The pollutant data collector 7 and the temperature and humidity data collector 8 monitor the relevant data of the polluted air inside the standardized detection box 1 through their probes respectively. A gas flow meter 9 is provided inside the front standardized detection box 1. The gas flow meter 9 is provided on the high-level interface 4 on the front side.

[0036] The top of the standardized testing box 1 is an open structure and is equipped with a top cover.

[0038] In the working state, the air pump 10 can suck the indoor polluted air into the front standardized detection box 1 through the air hood 12 and the front low-position interface 3, and at the same time, discharge the original air in the standardized detection box 1 through the front high-position interface 4. After the indoor polluted air is collected inside the front standardized detection box 1, and the front standardized detection box 1 is full of indoor polluted air, the value of the pollutant data collector 7 is stable, and the valves of the front low-position interface 3 and the front high-position interface 4 are closed respectively, and the air pump 10 is turned off. After that, the air hood 12 is removed, and the other end of the air duct 2 on the left is connected to the air inlet end of the front low-position interface 3, and at the same time, the other end of the air duct 2 on the right is connected to the air outlet end of the front high-position interface 4, and then the air pump 10 is turned on, and the two standardized detection boxes 1 and the two air ducts 2 form a closed circulation loop.

[0039] In one embodiment, for the above-mentioned mixing device, the mixing device includes a fan master control 6 and four fans 5. The fan master control 6 is arranged on the outer side wall of the standardized detection box 1, and the blades of the fans 5 are metal blades. The four fans 5 are arranged inside the standardized detection box 1, two of which are installed at intervals on the upper rear side of the standardized detection box 1, and the other two fans 5 are installed at intervals on the lower front side of the standardized detection box 1. The signal ports of the four fans 5 are all connected to the fan master control 6 for communication. The fan master control 6 controls the working status of the four fans 5 respectively. After the four fans 5 are turned on, the gas flow in the standardized detection box 1 can be accelerated, so that the polluted air is evenly mixed with the air in the standardized detection box 1 at the rear, and the accuracy of the monitoring data is ensured.

[0040] A filter paper board 13 and a sample tray 15 are provided inside the standardized detection box 1 at the rear side. The filter paper board 13 and the sample tray 15 are both made of transparent hard glass materials. The sample tray 15 is horizontally placed and installed at the lower part of the standardized detection box 1, and the filter paper board 13 is horizontally arranged above the sample tray 15.

[0041] Specifically, two protruding support bars are provided inside the standardized detection box 1, and the two protruding support bars are symmetrically fixed on the left and right inner walls of the standardized detection box 1. The filter paper board 13 has a number of regularly opened through holes, and its left and right sides are built on the upper surfaces of the two protruding support bars. The two protruding support bars support the filter paper board 13, so that the filter paper board 13 maintains a horizontal state at the rear side of the standardized detection box 1, and the filter paper board 13 is used to place glass fiber filter paper.

[0042] The working principle or general working process of a rapid and accurate air pollutant purification detection system is as follows: First, install the mixing device and the detection device on the standardized detection box 1 respectively to assemble into a material detection box, and connect one end of the two air ducts 2 to the low-level interface 3 and the high-level interface 4 of the material detection box respectively. After opening the top cover of the material detection box to place the detection material, close the top cover of the material detection box and the valves of the low-level interface 3 and the high-level interface 4. If the detection material is liquid, it is necessary to install a filter paper board 13, and fix the filter paper evenly coated with the experimental material on the filter paper board 13; if the detection object is a material in a gel or solid state, the detection sample is evenly placed on the sample tray 15.

[0043] The same mixing device and detection device are installed on another standardized detection box 1, and an air suction pump 10 is installed inside the standardized detection box 1. At the same time, an air suction hood 12 with a filter membrane 11 inside is installed on the low-level interface 3 of the standardized detection box 1 to assemble a gas collecting box. The top cover of the gas collecting box and the valves of the low-level interface 3 and the high-level interface 4 of the gas collecting box are closed.

[0044] Transfer the separately assembled gas collection box and material detection box to an indoor environment with air pollutants, open the valves of the low-level interface 3 and the high-level interface 4 of the gas collection box, start the suction pump 10, and the air pollutants in the indoor environment continuously enter the gas collection box until the measured data of the pollutant data collector 7 stabilizes, indicating that the original gas in the gas collection box is completely replaced by the indoor air containing pollutants. At this time, close the suction pump 10 and the valves of the low-level interface 3 and the high-level interface 4 of the gas collection box, and then remove the suction hood 12 of the low-level interface 3 of the gas collection box.

[0045] Afterwards, the other ends of the two air ducts 2 are connected to the low-level interface 3 and the high-level interface 4 of the gas collection box respectively. After the connection is completed, the rapid and accurate air pollutant purification detection system is formed to record the concentration of air pollutants in the gas collection box at this time. The low-level interface 3 and the high-level interface 4 of the gas collection box are connected to the low-level interface 3 and the high-level interface 4 of the material detection box through two air ducts 2 to form an air circulation system. Turn on the suction pump 10 of the gas collection box, all valves at the low-level interface 3 and the high-level interface 4 and the fan master control 6 switch in sequence, the air pollutants in the gas collection box are mixed with the air in the material detection box and continue to circulate, and when the data of the pollutant data collector 7 of the two boxes are basically the same and no longer change, record the pollutant concentration, temperature, humidity and airflow speed at this time. Theoretically, under the temperature, humidity and airflow speed conditions at this time, the purification efficiency of the detection material per unit space can be obtained.
