The invention relates to a dehumidifier, in particular to a structure improvement of a dehumidifier capable of recycling a cooled heat source of coal gas. The dehumidifier comprises a shell as well as a pre-cooling heat exchanger (2), a cold water cooler (3), a brine cooler (4) and a recuperative heater (5) which are arranged inside the shell and connected in sequence. The dehumidifier is characterized in that the internal medium of the pre-cooling heat exchanger (2) and the internal medium of the recuperative heater (5) are connected through a recycling pipe (6). Therefore, the dehumidifier provided by the invention has the advantages of satisfying a basic dehumidifying function, realizing residual-heat utilization inside a system and reducing operation cost by flexibly using the two-level dehumidifier comprising the cold water cooler and the brine cooler in operation.
