Abstract
A disposal unit for the safe disposal of aerosol containers and the like pressurized containers for inflammable gases or toxic chemicals, in which the containers are punctured or otherwise destroyed, by for example a shredder fed from a sealed hopper, and separated from fluid initially contained therein, in an enclosure through which a stream of air passes to an exhaust outlet but which is otherwise sealed against the egress of gases at normal operating temperatures and pressures. The stream of air passing through the enclosure is made sufficient to dilute the gases released following destruction of the containers to a level below the flash point of the gas/air mixture.
Claims11
A method of disposing of containers for aerosols, inflamable gases and toxic chemicals comprising the steps of:
- destroying said containers, by puncturing or otherwise, within an enclosure;
- separating fluid and gases initially contained within said containers from the destroyed containers;
- drawing a stream of air through a region having said destroyed containers and separated fluid to an exhaust outlet;
- said stream of air being sufficient to dilute any gases released by destruction of the containers to a level below the flash point of the gas and air mixture;
- conveying the destroyed containers on a continuous belt to a location outside said enclosure;
- draining through said continuous belt fluids separated from the containers during destruction;
- collecting the drained fluids into a bath below said continuous belt;
- heating the fluids drained into said bath;
- otherwise sealing said enclosure against the egress of gas at normal operating temperatures and pressures from said enclosure.
A disposal unit for containers of aerosols, inflammable gases, and toxic chemicals comprising:
- an enclosure;
- means for receiving said containers within said enclosure;
- means for destroying received containers, by puncturing or otherwise, thereby to separate said containers from their contents;
- means for drawing a stream of air through said enclosure, in the vicinity of the destroyed containers, to an exhaust outlet;
- means for otherwise sealing said enclosure against the egress of gas at normal operating temperatures and pressures;
- a conveyer having a continuous belt and positioned to receive destroyed containers, said conveyer extending out of said enclosure through a discharge opening;
- a bath positioned to receive liquid contents separated from said containers through said conveyer;
- said conveyer being permeable to liquid to permit liquids separated from said containers to collect in said bath;
- means for heating the liquid collected in said bath.
