The utility model discloses can go on fast multiple hazardous gas such as the nitrogen oxide in the mist, carbon monoxide, sulfur dioxide, metal vapor, the accurate detection.
Description
Technical field
The utility model relates to mixed gas and detects analysis technical field, is specifically related to a kind of toxic and harmful real-time detection apparatus.
Background technology
Along with the modern industry scale constantly expands, create the multiple toxic and harmfuls such as a large amount of oxides of nitrogen, carbon monoxide, sulphuric dioxide, metallic vapour in the process, detect above-mentioned toxic and harmful, to improving atmospheric environment, there is important directive significance.Carry out sampling and quantitatively detect being the prerequisite of it being carried out to qualitative recognition to toxic and harmful.And in detection space there is the impact such as skewness and environmental factor interference in gas usually, when there is mixing in multiple harmful gas, between gas, interference causes major component Character losing mutually, conventional detection method is difficult to certain composition responding tested gas selectively, has larger impact to the precision of gasmetry.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of toxic and harmful real-time detection apparatus, can carry out the multiple toxic and harmful in mixed gas detecting fast, accurately.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of toxic and harmful real-time detection apparatus, comprise sampling box, the bottom of sampling box is provided with the blower fan of exhausting outside box, the perisporium of sampling box is provided with and multiplely leads to detection space admission line everywhere respectively, be provided with the sensor array be made up of multiple toxic and harmful sensor in sampling box, and the output terminal of each sensor is connected with sampling controller respectively.
Further, described sensor array is listed in sampling box and is provided with one or more, and is respectively one or more in NOx sensor array, carbon monoxide transducer array, SO 2 sensor array or metallic vapour sensor array.
Further, described multiple sensors array isoplanar in sampling box is laid.
Further, multiple toxic and harmful sensor settings of sensor array are formed on wire side.
Further, described toxic and harmful sensor is that photoionization formula, electric chemical formula or infrared ray measure device.
The beneficial effect adopting technique scheme to produce is:
The utility model can carry out detecting fast, accurately to multiple toxic and harmfuls such as the oxides of nitrogen in mixed gas, carbon monoxide, sulphuric dioxide, metallic vapours.The utility model uses bionics (human olfactory) principle, adopt active detection means, the gas of different for many places in detection space sampled point is drawn in enclosed sampling box and detects again, overcome the uneven interference brought with environmental factor of distribution of gas in detection space.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in the figure, the utility model discloses a kind of toxic and harmful real-time detection apparatus, comprise sampling box 1, the bottom of sampling box 1 is provided with the blower fan 2 of exhausting outside box, the perisporium of sampling box 1 is provided with and multiplely leads to detection space admission line 3 everywhere respectively, be provided with the sensor array be made up of multiple toxic and harmful sensor in sampling box 1, and the output terminal of each sensor is connected with sampling controller respectively.Multiple toxic and harmful sensor settings of composition sensor array are on wire side, and during detection, gas can pass through from the mesh wire side, does not affect the flowing of gas.Sensor array is listed in sampling box 1 and is provided with one or more, and is respectively one or more in NOx sensor array, carbon monoxide transducer array, SO 2 sensor array or metallic vapour sensor array.When adopting multiple sensors array, multiple sensors array isoplanar in sampling box 1 is laid.Toxic and harmful sensor is that photoionization formula, electric chemical formula or infrared ray measure device, and structure multiple sensors array, to overcome the cross-sensitivity between all kinds of gas sensor.
The utility model achieves and detects in real time the signal of the multiple toxic and harmfuls such as oxides of nitrogen, carbon monoxide, sulphuric dioxide, metallic vapour, utilizes gas sensor array to carry out detection to gas and has fast response time, highly sensitive and make the advantages such as simple.The utility model uses bionics (human olfactory) principle, use for reference " active detection " means that some is similar, the gas of different for many places sampled point is drawn in airtight sampling box 1 and detects again, overcome the uneven interference brought with environmental factor of distribution of gas in detection space.Sampling controller of the present utility model controls testing process, and stores testing result, and testing result carries out the input signal as neural network recognization system after signal transacting, to carry out qualitative recognition to mixed gas.
