PROBLEM TO BE SOLVED: To provide a solid-liquid separation device which separates a solid-liquid mixture into solid and liquid using a liquefied substance prepared by pressurizing gaseous substance to the saturated vapor pressure thereof or higher, the running cost of which is reduced by reducing an amount of use of the liquefied substance and the safety of which can be improved.SOLUTION: There is provided the solid-liquid separation device for individually separating a solid-liquid mixture using a gaseous substance which is converted to a liquid at a saturated vapor pressure or higher. The device comprises: a compressor 5 for compressing the substance; a chiller 34 for liquefying the high-temperature high-pressure substance after being compressed ; an accumulator 6 for storing a liquefied substance; a valve 11 for controlling the flow of the liquefied substance at a position downstream of the accumulator; an atomizer capable of spraying the liquefied gas as a droplet at a position downstream of the valve; a treatment tank 2 capable of being filled with the mixture and having the vaporizer at an upper part; a filter for preventing outflow of a solid from the treatment tank 2; and a vaporizer 7 for vaporizing the substance from the mixture flowing out from the treatment tank 2. The upper space in the treatment tank 2 is filled with a substance in a gaseous state.SELECTED DRAWING: Figure 1 |
