DEVICE AND METHOD FOR PROCESSING OF SPRAY CANS

WIPO Patent Application WO/2019/216761

A3

Device for processing of spray cans, the de vice comprising a first space, separating means for separating spray cans in the first space, a second space, first transport means for transporting gas from the first space to the second space, and compressing means for compressing gas in the second space, characterized in that the device also comprises second transport means configured and suitable for transporting heat, released during compressing of the gas, from the second space to the first space. The second transport means for instance comprise here a conduit for having a fluid, preferably a coolant, flow therethrough. Also method for processing of spray cans by means of such a device. The term 'space' is understood in the context of the invention to mean 'a determined part of the device'. When process parameters such as heat flow, gas flow, temperatures and pressures are.set correctly, solid material, active substance and propellant are discharged separately, and can then separately be further processed, destroyed or reused. Heat which is released during the compressing / condensing of gas in the second space is used to compensate for cold which is released during expansion of gas and/or evaporation of liquid in the first space. Thus it is brought about that the first space does not become too cold and the second space does not become too hot, while the whole process is energy-efficient.
