After a period of absorption, the formaldehyde concentration in the detection box 1 is detected by the formaldehyde detector 13, and the formaldehyde purification rate of the material is obtained according to the corresponding logic, and the detection is completed;

[0030] like Figure 1 , Figure 2 , Figure 4-Figure 8As shown, the displacement unit in the detection box 1 includes a lifting mechanism 301, which is installed on the detection box 1.

The heat exchange tube 14 and the temperature sensor 18 work using existing technology. During the detection process, the temperature in the detection box 1 is detected by the temperature sensor 18, and the detection result is transmitted to the external controller. According to the temperature detected by the temperature sensor 18, the external temperature control device transports the heat exchange material to the heat exchange tube 14 in the detection box 1, and the temperature in the detection box 1 is adjusted by the heat exchange tube 14, thereby adjusting the temperature in the detection box 1, so that the detection box 1 is at the optimal formaldehyde adsorption temperature, thereby increasing the speed at which the adsorption material absorbs formaldehyde and reducing the time for detecting the formaldehyde purification rate of diatom mud.
