Zusammenfassung:	The invention discloses a method and a device for cooling and dehydrating blast furnace gas desorption gas, relates to the technical field of blast furnace gas desorption gas recycling, and aims to solve the problem that an existing device cannot meet the separation requirement of the blast furnace gas desorption gas. The method comprises the following steps: introducing blast furnace gas desorbed gas into a lithium bromide refrigerator for preliminary cooling, continuing to introduce the cooled gas into an indirect heat exchanger for secondary cooling, and dehydrating the obtained gas-water mixed medium through a rotational flow dehydrator; wherein cooling water of the indirect heat exchanger comes from outlet water of an evaporator of the lithium bromide refrigerator; the steps and the structure are simple, the blast furnace gas desorption gas can be cooled and dehydrated so as to meet the requirements of the subsequent process, the lithium bromide refrigerator is used for conducting primary cooling, energy
