Abstract
A chemical waste collection and disposal system for fluorescent lamps that allows for the safe collection and disposal of crushed or broken fluorescent lamps, while recovering substantially 100% of the hazardous mercury vapors contained within the lamps. A fluorescent lamp is inserted within a drum and broken into fragments by one or more blades, with the fragment falling to the bottom of the drum. The mercury vapors that are emitted from the broken fluorescent lamps are forced out of the drum by negative positive pressure created by a vacuum/filter assembly. Once through the filter assembly, which includes a HEPA filter and activated carbon filter, the gases are permitted to escape into the environment virtually 100% free of mercury toxins.
Claims19
A fluorescent lamp collection and disposal system, said fluorescent lamp containing a hazardous material comprising:
- a housing having a side wall and bottom surface defining an interior area;
- a cover member having a top surface, said cover member including a tube member protruding upward from said top surface for receiving a fluorescent lamp and providing access through the cover member to the interior area of the housing for the fluorescent lamp;
- means for breaking the fluorescent lamp received by said tube member into a plurality of pieces and releasing a hazardous material contained by the fluorescent lamp prior to being broken;
- a hose member connected at a first end to the cover member such that the hose member is in communication with the interior area of the housing:
- a multi stage filtering and vacuum assembly having a plurality of filter members and a vacuum motor, said vacuum motor positioned after a final filter of the multi stage filtering and vacuum assembly, said vacuum motor creating a negative pressure vacuum within the interior of the housing;
- wherein a second end of the hose member is connected to the multi-stage filtering assembly such that the hose member is in communication with a first filter member of the multi stage filtering assembly;
- wherein the negative pressure vacuum created by said vacuum motor causes at least a substantial portion of the hazardous material to be drawn through the hose member and into the multi stage filtering assembly wherein at the end of filtering by the multi-stage filtering assembly substantially hazardous material free gas is exhausted out of said multi-stage filtering assembly;
- wherein at least some pieces of the plurality of pieces of the broken fluorescent lamp are retained within the interior area of said housing;
- wherein said cover member further including a lamp receiving member depending upward from the top surface of the cover member, said lamp receiving member having a bottom surface, sidewalls and a top portion, wherein said top portion is connected to said bottom surface such that the movement of the top portion to an open position moves the bottom surface to a closed position for placement within said lamp receiving member of a lamp to be crushed and the movement of the top portion to a closed position moves the bottom surface to an open position to permit the placed lamp to enter the interior of the housing and for breakage by said means for breaking.

A fluorescent lamp collection and disposal system, said fluorescent lamp containing a hazardous material comprising:
- a drum having a side wall and bottom surface defining an interior area;
- a cover member having a top surface, said cover member including a tube member protruding upward from said top surface for receiving a linear fluorescent lamp and providing access through the cover member to the interior area of the drum for the linear fluorescent lamp, said cover member further including a lamp receiving member depending upward from the top surface of the cover member, said lamp receiving member having a bottom surface, sidewalls and a top portion, wherein said top portion is connected to said bottom surface such that the movement of the top portion to an open position moves the bottom surface to a closed position for placement within said lamp receiving member of a non-linear lamp to be crushed and the movement of the top portion to a closed position moves the bottom surface to an open position to permit the placed non-linear lamp to enter the interior of the housing;
- means for breaking a linear fluorescent lamp received by said tube member or a non-linear lamp placed within said lamp receiving member into a plurality of pieces and releasing a previously contained mercury vapor from the linear fluorescent lamp or non-linear lamp prior to being broken;
- a vacuum hose connected at a first end to the cover member such that the hose member is in communication with the interior area of the housing;
- a multi stage filtering and vacuum assembly having a plurality of filter members and a vacuum motor, said vacuum motor positioned after a final filter of the multi stage filtering and vacuum assembly, said vacuum motor creating a negative pressure vacuum within the interior of the housing;
- wherein a second end of the hose member is connected to the multi-stage filtering assembly such that the hose member is in communication with a first filter member of the multi stage filtering assembly;
- wherein the negative pressure vacuum created by said vacuum motor causes at least a substantial portion of the mercury vapor to be drawn through the hose member and into the multi stage filtering assembly wherein at the end of filtering by the multi-stage filtering assembly substantially mercury vapor free gas is exhausted out of said multi-stage filtering assembly;
- wherein at least some pieces of the plurality of pieces of the broken linear fluorescent lamp or non-linear lamp are retained within the interior area of said housing.
