The utility model discloses a tobacco laser unpacking soot removing device which is characterized by comprising a box body, wherein the box body is provided with a smoke inlet and a drain outlet and is capable of accommodating a dust removing liquid, the box body is internally provided with a smoke distribution pipeline, and a smoke outlet is formed in the smoke distribution pipeline; the smoke distribution pipeline is communicated with the smoke inlet, the height of the liquid level of the dust removing liquid is higher than that of the smoke distribution pipeline, and a clearance is reserved between the liquid level of the dust removing liquid and the top of the box body; the upper end of the box body is provided with an exhaust fan, and an exhaust pipe of the exhaust fan is communicated with the interior of the box body. The tobacco laser unpacking soot removing device has the beneficial effects that the negative pressure is formed in the device by virtue of the exhaust fan, the theory that the pressure in the equipment is less than that of the atmosphere is used, so that the colloidal harmful gas is inhaled into a smoke suction removing machine by virtue of a laser drawing box machine, and the colloidal harmful gas is discharged out of the device by virtue of the water filtration. The contact area of the liquid is bigger due to the water filtration mode; because the liquid contains a glue melting additive, a colloidal matter in gas can be better and faster dissolved, only the water in the device needs to be replaced regularly, so that the cost of consumables is greatly lowered.
