Abstract
A method for treating hazardous waste contained in barrels (1), in which method the barrels (1) are cut up and/or crushed in a shearing device (9) so that the created waste mass can be pumped into a kiln furnace (4) by means of a paste pump.
Claims21
A method for treating waste contained in vessels such as barrels and the like, particularly hazardous waste, the said method including transporting the vessels (1) containing the waste by means of a charging conveyor (2), and burning the waste in a furnace, characterized in that the vessels (1) are shifted from the charging conveyor (2) into a shearing device (9), where the vessels are cut up and/or pressed to crush so that the waste can be treated with a paste pump (11), metal is separated from the waste before the waste is pumped into the kiln furnace (4) by means of the paste pump (11), and the separated metal is transported, by means of a band conveyor (13), into the same furnace as the waste proper.
A method for treating waste contained in vessels such as barrels and the like, particularly the hazardous waste, the said method including transporting the vessels (1) containing the waste by means of a charging conveyor (2), and burning the waste in a furnace, characterized in that the vessels (1) are shifted from the charging conveyor (2) into a shearing device (9), where the vessels are cut up and/or pressed to crush so that the waste can be treated with a so-called paste pump (11), and, in order to eliminate the danger of fire, an inert gas atmosphere is maintained within the shearing device (9).
A method for treating waste material, comprising delivering the waste material to a treatment location in a closed metal vessel, subjecting the vessel to a shearing operation, whereby the vessel is broken or crushed and the contents of the vessel are released, and conveying released waste material and parts of the broken or crushed vessel into a furnace.
A method for treating waste material that includes metal, comprising delivering the waste material to a treatment location in a closed vessel, subjecting the vessel to a shearing operation, whereby the vessel is broken or crushed and the contents of the vessel are released, separating metallic waste material from the non-metallic waste material, conveying the non-metallic waste material into the furnace, and conveying the separated metallic waste material into the furnace separately from the non-metallic waste material.
A method for treating waste material, comprising delivering the waste material to a treatment location in a closed vessel, subjecting the vessel to a shearing operation, whereby the vessel is broken or crushed and the contents of the vessel are released, the shearing operation being carried out under an inert gas atmosphere, and conveying released waste material into a furnace.
