[0031] The cooling assembly can cool the second adsorption tower 18 by the cooled airflow, thereby preventing the use of dry product gas to cool the second adsorption tower 18, and preventing the occurrence of resource waste, thereby increasing the usability of the adsorption dryer in use.

[0032] The first heat exchanger 20 can cooperate with the second heat exchanger 23 to cool the gas twice, thereby improving the cooling efficiency of the adsorption dryer.

[0036] The second adsorption tower 18 and the fourth butterfly valve 4 are fixedly connected with a seventh butterfly valve 2, the seventh butterfly valve 2 and the first adsorption tower 17 are fixedly connected with an eighth butterfly valve 1, one end of the first adsorption tower 17 is fixedly connected with a first check valve 15, the first check valve 15 and the second adsorption tower 18 are fixedly connected with a second check valve 16, the first check valve 15 and the second check valve 16 are provided with an air outlet pipe 26, and the eighth butterfly valve 1 and the seventh butterfly valve 2 are provided with an air inlet pipe 27.
