Claims23
A filtration system for removing a particulate material, comprising:
- a housing having an internally formed air path communicating between an inlet for incoming polluted air containing particulate material and an air outlet for emitting clean air filtered by removing the particulate material;
- a collection system provided in the air stream to collect the particulate material, said collection system including at least one collection belt;
- a cleaning system provided to clean the collected particulate material from the at least one collection belt;
- and
- a removal system for removing the collected particulate material from said housing;
- wherein said collection system comprises a toothed drive roll configured to engage openings in said at least one collection belt and thereby drive said at least one collection belt;
- and
- wherein said cleaning system comprises a toothed cleaning roll meshing with said toothed drive roll, said toothed drive roll cleaning the at least one collection belt engaged therewith, and said toothed cleaning roll cleaning the toothed drive roll.
A method of removing a particulate material from an air stream comprising:
- passing an air stream through a housing having an internally formed air path communicating between an inlet for incoming polluted air containing particulate material and an air outlet for emitting clean air filtered by removing the particulate material;
- collecting particulate from the air stream with a collection system including at least one collection belt;
- cleaning the collected particulate material from the at least one collection belt;
- and
- removing the collected particulate material from said housing;
- wherein said cleaning step includes driving the at least one collection belt on a toothed drive roll comprising a plurality of teeth;
- wherein said cleaning step further includes providing a toothed cleaning roll meshing with the toothed drive roll so as to remove particulate material from the toothed drive roll.
A filtration system for removing a particulate material, comprising:
- a housing having an internally formed air path communicating between an inlet for incoming polluted air containing particulate material and an air outlet for emitting clean air filtered by removing the particulate material;
- a collection system provided in the air stream to collect the particulate material, said collection system including at least one collection belt;
- a cleaning system provided to clean the collected particulate material from the at least one collection belt;
- and
- a removal system for removing the collected particulate material from said housing;
- wherein said removal system comprises a collection chamber and an air lock, particulate material collected from the at least one collection belt being collected in said collection chamber and removed from said housing via said air lock.
