Abstract
The utility model relates to an indoor air quality detector which is mainly composed of a timing module, a constant-current sampling device, an absorption device, a lighting box and a data acquisition and processing module. The timing module is connected with the constant-current sampling device which is connected with the lighting box, the lighting box is connected with the data acquisition and processing module, and the data acquisition and processing module is connected with a printing device. The lighting box comprises a photoelectric sensor, and absorption liquid is arranged in the absorption device. The indoor air quality detector achieves temperature and humidity compensation in formaldehyde measuring and greatly improves measuring accuracy under different measuring environments.
Description
Technical field
The utility model relates to the collection method of formaldehyde gas, the detection method of penetrability, and what be specifically related to is determining instrument of indoor air quality.
Background technology
At present, methylene oxide detecting instrument adopts absorption reagent collection formaldehyde gas, detection test solution penetrability, processor to table look-up and draw the method for content of formaldehyde for the detection of content of formaldehyde; The topmost problem that exists in the traditional instrument design is to evade the impact of the humiture of measurement environment for the test solution penetrability; Secondly, the table of comparisons of penetrability and concentration of formaldehyde, need to be stored in detector in advance, makes continuous data relationship discretize, when the detector processor is tabled look-up, can produce larger error; Finally, there is the unsettled stage in the output of luminosity sensor, has had a strong impact on accuracy of detection.
The utility model content
In order to improve penetrability to the degree of accuracy of concentration of formaldehyde conversion and to overcome the unstable output of photoelectric sensor, the utility model has provided a kind of new indoor air quality detector, can pass through temperature and humidity compensation algorithm correcting measured results; And trueness error that " look-up table " bring and the unstable output of sensor have been avoided.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of determining instrument of indoor air quality, mainly by time block, constant-flow sampling device, absorption plant, daylighting box and digital sampling and processing, formed, described time block connects constant-flow sampling device, constant-flow sampling device connects the daylighting box, daylighting box connection data acquisition processing module, digital sampling and processing connects printing device.
Described daylighting box contains photoelectric sensor.
In described absorption plant, contain absorption liquid.
Described digital sampling and processing contains Temperature Humidity Sensor.
The beneficial effects of the utility model are: realized the temperature and humidity compensation of formaldehyde measurement, improved greatly the measuring accuracy under the different measuring environment.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Fig. 1 is structural representation of the present utility model.
The 1-time block; The 2-constant-flow sampling device; The 3-absorption plant; 4-daylighting box; The 5-digital sampling and processing; The 6-printing device.
Embodiment
By shown in Figure 1, at first by constant-flow sampling device 2, gather gas sample, time block 1 is guaranteed the accuracy of collection capacity; Absorption liquid in gas sample and absorption plant 3 reflects that fully rear generation detects sample, put into daylighting box 4, photoelectric sensor detects the test solution penetrability, be input to digital sampling and processing 5, the humiture situation that digital sampling and processing 5 will be measured in real time joins in the middle of the calculating to measurement result, realizes the error compensation of humiture, improves measuring accuracy, measurement result instant playback subsequently, and can by printing device 6, print as required.
