And after the high-temperature smoke enters the gas bin 530, the smoke is liquefied in the gas bin 530 when encountering cold due to the temperature difference between the smoke and the gas bin 530, and a smoke water outlet can be arranged at the bottom of the gas bin 530 or at the position of the side wall close to the bottom, so that the condensed water in the gas bin 530 can be conveniently pumped out by the smoke water draining pump 531. The diaphragm pump 580 operates to draw in the flue gas from the flue gas inlet nozzle 520 and then to pump the flue gas into the electrochemical sensor assembly 560, and the flue gas liquefies in the electrochemical sensor assembly 560 when it is cooled due to the temperature difference between the flue gas and the electrochemical sensor assembly 560, and the flue gas drain pump 570 pumps out the condensed water in the electrochemical sensor assembly 560 through the flue gas drain port 571. The apparatus body 500 may be provided with a waste water outlet, and the smoke drain pump 531 and the smoke drain pump 570 are respectively communicated with the waste water outlet, so that condensed water extracted by the smoke drain pump 531 and the smoke drain pump 570 can be discharged through the waste water outlet. Peristaltic pumps may be used for the smoke drain pump 531 and the smoke drain pump 570. The condensed water in the smoke sampling device can be discharged by the smoke draining pump 531 of the embodiment, and the condensed water of the electrochemical sensor component in the smoke sampling device can be discharged by the smoke draining pump 570, so that the service life of the electromechanical and measuring devices is prolonged, and the accuracy of the detection result is improved.

The sensor 563 may employ an O2 sensor, an SO2 sensor, an NO2 sensor, a CO2 sensor, or an H2S sensor, and the number of sensors may be configured according to the kind to be measured. Each sensor 563 is correspondingly installed in the sensor installation opening 565, the front plate 561 and the rear plate 562 enclose the sensor 563, the drain 572 and the air duct 564,

therefore, the flue gas enters the electrochemical sensor assembly 560 through the air inlet 567, then passes through the plurality of sensors 563 one by one through the air flue 564, finally is discharged from the air outlet 568, condensed water is formed by the flue gas in the air flue 564 when the flue gas is cooled and liquefied, and the flue gas drainage pump 570 discharges the condensed water in the air flue 564 through the flue gas drainage port 571, so that the service life of the sensors 563 is prolonged, and the accuracy of detection results is improved.

Through multiple experiments, it is found that when the flue gas flows through the plurality of sensors 563 through the air flue 564, the high-temperature flue gas is mainly concentrated at the first sensor 563 and the second sensor 563 and is liquefied most when encountering cold, and the reason is probably that after the high-temperature flue gas is liquefied when encountering cold at the first sensor 563 and the second sensor 563, the temperature of the flue gas is gradually reduced, the temperature difference between the flue gas after the temperature reduction and the following sensors 563 is not very large, and condensed water is less formed when the other subsequent sensors 563 are liquefied when encountering cold. Therefore, in order to drain the main condensate water at the fastest speed, two drainage channels 572 are provided, the first ends of the two drainage channels 572 are respectively communicated with the first installation opening and the second installation opening, the tail ends of the two drainage channels 572 are respectively communicated with the fume drainage opening 571, the fume drainage pump 570 drains the condensate water concentrated at the first sensor 563 and the second sensor 563 through the fume drainage opening 571 and the two drainage channels 572, and of course, after the condensate water at the first sensor 563 and the second sensor 563 is drained, the fume drainage pump 570 continues to work, and a small amount of condensate water at the other sensor installation openings 565 also reversely flows to the fume drainage opening 571 along the air flue 564 and is then drained. As shown in fig. 3, the first and second sensors 563 and the fume outlet 571 are in an inverted triangle shape, so that condensed water at the first and second sensors 563 can be more conveniently discharged.
