Thermal cleaning and separation of metal parts is performed by a stator from an electric motor. Windings embedded in an organic, insulating material are placed and heated to 250°–500° C. under controlled conditions in a heating chamber, evaporating organic material and loosened windings. Flue gas is evaporated organic substances conducted through a closed pipe system to a condensator, where organic gases condense. The pipe system is designed so that condensate is conducted-on in the closed pipe system to a partly liquid filled vessel. Contents of this vessel are air and water that flow concurrently with the condensed flue gas as condensate, increasing content of organic material in the vessel and separating condensate from air. Air may be conducted to the oven for renewed absorption of organic material. All organic material evaporated from the heating chamber is collected in the vessel for later disposal in an environmentally correct and secure way.
A method for thermal cleaning and separating of organic substances from metal parts, comprising the steps of placing and heating the organic substances and metal parts under controlled conditions in a heating chamber containing air, evaporating the organic substances, loosening the organic substances from the metal parts, conducting the evaporated organic substances via a closed pipe system to at least one condensator, condensing the evaporated organic substances to form condensate, conveying a mixture of the condensate from the condensator and the air from the heating chamber to a partly liquid filled vessel, cleaning the air, and supplying the cleaned air back to the heating chamber for use in a new heating cycle.
A machine for thermal cleaning and separation of metal parts from organic material comprising an oven including a heating chamber having air for receiving and heating the metal parts and the organic material, gas formed by separation and evaporation of the organic material from the metal parts, at least one condensator, a first closed pipe system connecting the heating chamber and the condensator for supplying the gas to the condensator, condensate formed in the condensator by condensing the gas, a partly liquid filled vessel connected to the condensator via the first closed pipe system, the condensate and the air being conducted from the condensator to the partly liquid filled vessel for absorption of the condensate and for generating cleaned air, and a second closed pipe system different from the first closed pipe system connecting the partially liquid filled vessel and the heating chamber for supplying the cleaned air from the partially liquid filled vessel back to the heating chamber for use in a new heating cycle.
