experiment example

[0034] Use the nano-polyaniline-activated carbon of the present invention as the gas sensor of the gas-sensitive material coating to test a variety of common indoor pollutant gases, and detect the detection limit concentration and detection reaction time of the gas sensor to different gases. The target gases are formaldehyde, toluene, xylene and nitrobenzene, each target gas is tested 3 times, and the average value of the 3 times is calculated. The experimental results are shown in Table 1;

[0035] Table 1

[0036] Limit concentration (ppm) response time (ms) formaldehyde 0.129 607 Toluene 0.057 324 Xylene 0.061 298 Nitrobenzene 0.059 326

[0037] Comprehensive above-mentioned experimental example, its experimental result shows, the detection area of ​​nano polyaniline-activated carbon sensor of the present invention is bigger, can detect multiple common indoor polluting gases, the concentration of detection limit is at a better ...

Abstract

The invention particularly discloses an activated carbon air purifier capable of detecting harmful gas. The activated carbon air purifier comprises an air purifier box, and further comprises a controller, an air inlet pump, an air outlet pump, an air blower, a filter layer set and gas sensors; the filter layer set is detachable; and the controller, the air inlet pump, the air outlet pump, the air blower, filter layers and the gas sensors are electrically connected. The air purifier is provided with the multiple gas sensors, the quality of air obtained before and after purification can be detected, and it is guaranteed that the quality of the purified air reaches the standard; the controller can assess the air quality according to preset procedures and controls the working states of the air inlet pump, the air outlet pump and the air blower in real time according to data of the gas sensors, and a control panel can input the quality of the air in a zone into the corresponding preset procedure; activated carbon is adopted in the air purifier, extra working waste cannot be generated in the working process, and the activated carbon air purifier is green and environment-friendly; and the air purifier has a wide market prospect.

Description

technical field [0001] The invention relates to the technical field of air purifiers, in particular to an activated carbon air purifier capable of detecting harmful gases. Background technique [0002] Air purifier refers to a device that can absorb, decompose or degrade various air pollutants. General pollutants include PM2.5, dust particles, benzene decoration pollution, bacteria, etc. With the rapid development of the economy, the degree of urbanization is getting higher and higher, and the air quality in urban and rural areas is getting worse and worse. People have higher and higher requirements for the air quality of the home environment, but the current air purifiers rarely have activated carbon purification treatment, and it is difficult to completely purify the air. Contents of the invention [0003] Aiming at the above-mentioned deficiencies of the prior art, the present invention provides an activated carbon air purifier capable of detecting harmful gases, which...
