According to this embodiment, in the first dehumidifying chamber 612, the adsorption mesh plate 611 adsorbs a large amount of moisture, and then flows to the second dehumidifying chamber 613 through the mesh holes of the adsorption mesh plate 611. In the second dehumidifying chamber 613, the adsorption mesh plate 611 can adsorb a small amount of moisture, thereby dehumidifying the gas. So that the drier gas can be delivered to the infrared detection device 50 for concentration detection. Compared with the prior art, the adsorption screen 611 is arranged to enable the adsorption screen to adsorb moisture of the flowing gas in the first dehumidifying chamber 612 and to adsorb moisture of the flowing gas in the first dehumidifying chamber 612 for the second time, so that the moisture content of the gas can be reduced, and the gas is ensured to be drier.

According to the embodiment, by the arrangement, the staff can intuitively grasp the current gas concentration and take early warning measures in time.
Referring to fig. 1, in some embodiments, the case 10 has at least two handles 13 disposed opposite to each other.
According to this embodiment, this is arranged so as to be easily taken by a worker.

According to this embodiment, after the suction pump 70 draws in the gas, the gas is monitored by the humidity detection meter 80. When the humidity of the gas meets the standard, the three-way electromagnetic valve 90 is communicated with the dehumidifying device 60, so that the gas enters the dehumidifying device 60 for dehumidification. Conversely, when the humidity of the gas does not meet the standard, the three-way electromagnetic valve 90 is directly communicated with the air cleaning device 20. In this way, on one hand, the detection efficiency can be improved, and on the other hand, the heating and drying time is reserved for the adsorption screen 611, so that the adsorption screen has good adsorption capacity.
In addition, a silica gel surface layer may be adhered to the inner wall of the first housing 61. Therefore, when the gas flows and contacts with the silica gel surface layer, the moisture in the gas can be adsorbed.
Specifically, the working principle of the infrared gas analyzer is as follows: after the gas is drawn in by the pump 70, the gas is monitored by the humidity sensor 80. When the humidity of the gas meets the standard, the three-way solenoid valve 90 is communicated with the intake pipe 6211 so that the gas flows from the intake chamber 621 to the first dehumidifying chamber 612. In the first dehumidifying chamber 612, the adsorption mesh plate 611 adsorbs a large amount of moisture, and then flows to the second dehumidifying chamber 613 through the mesh holes of the adsorption mesh plate 611. In the second dehumidifying chamber 613, the adsorption mesh plate 611 may adsorb a small amount of moisture. The drier air then flows to the exhaust chamber 622 and from the exhaust 6221 through the air cleaning device 20, the air flow meter 30 and the vacuum pump 40 to the infrared detection device 50 while being detected at the infrared detection device 50.
It should be noted that, the model specifications of the gas flowmeter 30, the vacuum pump 40, the electric heating tube, the electric heating wire, the air pump 70, the humidity detecting instrument 80 and the three-way electromagnetic valve 90 need to be determined by selecting the model according to the actual specifications of the device, and the specific model selection calculation method adopts the prior art in the field, so that detailed description is omitted.
