when the gas detection device is used, gas subjected to adsorption treatment is injected into the inner position of the detection box 3 through the first connecting pipe 8, the detector 18 detects the content of acid gas in the gas, when the content of acid gas in the gas is lower than a threshold value, the second exhaust pipe 7 is in a communicated state, the gas is discharged through the second exhaust pipe 7 at the moment, the discharged gas is qualified, when the content of acid gas in the gas is higher than the threshold value, information is transmitted into the control box 15 at the moment, the control box 15 closes the valve of the second exhaust pipe 7 and opens the valve of the first exhaust pipe 6, so that the gas is discharged through the first exhaust pipe 6 and enters the injection pipe 5 to be subjected to adsorption treatment again, the gas introduced after the adsorption liquid is saturated is prevented from being incompletely discharged, and the perforations 17 are arranged in a staggered mode, the retention time of the gas in the detection box 3 is prolonged, and detection is convenient;

when the adsorption liquid cannot be adsorbed during use, the second pump body 44 is actuated to suck out the adsorption liquid in the adsorption tank 1 through the seventh connecting pipe 50 and inject the adsorption liquid into the temporary storage tank 43, so that the second floating plate 47 moves upwards until the trigger switch 49 is pressed, at this time, all the adsorption liquid in the adsorption tank 1 is injected into the temporary storage tank 43, the trigger switch 49 actuates the fourth pump body 40 to suck out the adsorption liquid in the active tank 4 through the eighth connecting pipe 41 and inject the adsorption liquid into the adsorption tank 1 through the fifth connecting pipe 42 for continuous adsorption, so that the continuity of adsorption operation is improved, and then the control box 15 actuates the third pump body 45 to inject the adsorption liquid in the temporary storage tank 43 into the active tank 4 through the sixth connecting pipe 46;

when the adsorption liquid is injected into the interior of the active tank 4, the adsorption liquid is heated through the temperature in the cooling liquid outside the active tank 4, so that the dissolution rate of the acid gas is reduced, so that the acid gas overflows, the activation of the adsorption liquid is accelerated, meanwhile, the recycling of heat energy is facilitated, the electric push rod 37 is started simultaneously, the electric push rod 37 drives the negative pressure plate 39 to move upwards, the lower end position of the negative pressure plate 39 forms negative pressure, the discharge efficiency of the acid gas is improved, the activation of the adsorption liquid is accelerated, and then, the air pump 35 is started, so that the discharged acid gas is discharged through the corrugated hose 38 and the fourth connecting pipe 36.
