Fig. 2 is the structural representation in sensor storehouse in the utility model;
Fig. 3 is the schematic diagram of the utility model middle filtrator.
Embodiment
For making the technical solution of the utility model and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, clear complete description is carried out to the technical scheme in the utility model embodiment:
A kind of gas concentration detection apparatus as depicted in figs. 1 and 2, comprise the housing of hardware, in housing, be provided with filtrator 1, gas production pump 3 and sensor storehouse 2, gas carries out filtration treatment by filtrator 1 and then carries out gas concentration detection entering sensor storehouse 2.Filtrator 1 is for carrying out Impurity removal to the gas collected; Gas production pump 3 carries out compression pressurized treatments to the gas after filtration; Accommodate multiple dissimilar sensor in sensor storehouse 2 and Concentration Testing is carried out to gas.
The concrete structure schematic diagram in sensor storehouse 2 as shown in Figure 2, sensor storehouse 2 can be a leveling board 4, one end of leveling board 4 is provided with air admission hole 5 and vent port 6, leveling board 4 is disposed with the shrinkage pool 7 of multiple accommodation sensor, the internal face of shrinkage pool 7 is provided with the through hole 8 for gas circulation.Under duty: the gas after filtration enters in sensor storehouse 2 along air admission hole 5, because the shrinkage pool 7 all by the effect of through hole 8 communicates, therefore gas forms the loop of a gas circulation under the effect of air admission hole 5, shrinkage pool 7, through hole 8 and vent port 6, owing to arranging the sensor of the different size detecting gas concentration information in shrinkage pool 7 inside thus realizing the Concentration Testing of gas.
Further, the particular type of the shrinkage pool 7 in sensor storehouse 2 as shown in Figure 2 and structure, specifically comprise standard interface 21 and a square expansion interface 22 of multiple circle.A flow sensor interface 23, temperature sensor interface 24 and multiple gas sensor interface 25 is at least comprised in standard interface 21.Standard interface 21 in the utility model is set to 14, is provided with digital sensor in wherein 12, and set temperature sensor interface 24 in two other standard interface 21, another arranges flow sensor interface 23.Square expansion interface 22 is for the sensor of special requirement.
Further, as shown in Figure 3: in housing, be arranged side by side identical cylindric style filter 1, two filtrators 1 of two dimensions control to use by three-way solenoid valve.Two filtrators 1 are drum symmetric design back-to-back.A filtrator 1 built with PP material filter core, in normal sample process particle filter, another filtrator 1 is equipped with rich hole mineral adsorbent filler, for provide during zero correction zero point air, two filtrators are controlled by three-way solenoid valve.When equipment gas production detects, gas passes through from being equipped with PP material filter core, enters sensor and is detected; Arrive the fixed time or detect minimum value consecutive variations and be less than more than 5% time, by controlling three-way solenoid valve, allowing gas through being equipped with the filtrator of rich hole mineral adsorbent filler, carrying out automatic zero point correction.
