The invention discloses a solution dehumidification device driven by low-temperature smoke gas, comprising a solution dehumidifier, a solution regenerator, a flue heater, a heat exchanger, a solution cooler, a concentrated solution trough, a diluted solution trough, a cooling tower, a water pump, a fan, a concentrated solution internal circulation pump, a concentrated solution external circulation pump, a diluted solution internal circulation pump, a diluted solution external circulation pump, a valve, an air inlet and an air outlet. The device takes a moisture-absorption solution as a dehumidizer to remove the water in the air; and the dehumidified air can be used for industrial combustion or used as the new air of an air conditioning system; and the device utilizes the low-temperature smoke gas exhausted by an industrial furnace as the heat source of the solution regenerator and drives the whole device to run by heating the solution with the flue heater. The device has the advantages of recovering the residual heat of the low-temperature smoke gas, saving energy resource, having high heat recovery rate and strong dehumidification capability, and the like.
