The invention discloses a device and a method for recovering organic solvents in flammable explosive high-
viscosity polymer waste. A far-
infrared furnace, a
buffer tank, a filter and a condenser are connected in sequence; the condenser is connected with a
solvent recovery tank while connected with a water tank via a
vacuum pump; the side surface of the water tank has an overflow port; the heatingelement of the far-
infrared furnace is a
silicon carbide plate arranged out of the furnace and coated with a far-
infrared paint; a far-infrared heating wire is arranged in the
silicon carbide plate; and one surface, coated with the far-infrared paint, of the
silicon carbide plate clings to the outer wall of the far-infrared furnace. According to the invention, waste
slurry blocks and solvents in flammable and explosive materials adhered onto
metal surfaces are recovered in a
vacuum state by heating and condensing; the far-infrared furnace is employed for heating, so uniform heating in the furnace is realized, local high temperature and open flames do not occur, and the phenomenon of flash explosion is eliminated; the waste
slurry blocks and the flammable and explosive melt materials adhered onto
metal surfaces are separated under high vacuum and high temperature, and the separated and evaporated flammable and explosive organic solvents are condensed into liquid which is collected for recycling; so
spinning solvents can be recycled,
raw material consumption is reduced, and production cost is lowered.
