Gas dehydration device for blast furnace

The utility model relates to the technical field of coal gas dehydration devices, and discloses a coal gas dehydration device for a blast furnace, which comprises a gas outlet pipe connected on a device body, the gas outlet pipe consists of two branch pipes, a dehydration assembly is connected between the two branch pipes, and the dehydration assembly comprises a connecting pipe. Two ends of the connecting pipe are respectively communicated with one branch pipe, and a filter element is fixedly connected in the connecting pipe. The connecting pipe is arranged between the branch pipes of the gas outlet pipe, the filter element is arranged in the connecting pipe, and the adsorption effect of the filter element on water vapor is utilized, so that secondary dehydration of coal gas is realized, the whole device can remove the water vapor in the coal gas as much as possible, and the dehydration effect of the coal gas is improved; therefore, the practicability and the safety of the coal gas are improved. 本实用新型涉及煤气脱水装
