Abstract:
An industrial dust collector, comprising:at least one solids-gas separating compartment comprising at least one solids-gas separator for removing large particulates of dust from a dusty gas stream to provide a partially dedusted gas stream; at least one inlet conduit connected to said solids-gas separating compartment for feeding said dusty gas stream to said solids-gas separating compartment; simultaneously operating multiple filter compartments comprising at least a first filtering compartment and a second filtering compartment, said filtering compartment cooperating with each other and operating and filtering at the same time in the absence of purging and cleaning filters therein for filtering said partially dedusted gas stream from said solids-gas separating compartment; said first filtering compartment positioned generally along side and spaced laterally away from said solids-gas separation compartment and in offset relationship thereto, rather than in vertical alignment or completely above said solids-gas separation compartment, said first filtering compartment having at least one first filter for filtering a first portion of said partially dedusted gas stream, at least one first compressed air tank communicating with said first filtering compartment, and at least one first air injector operatively connected to said first compressed air tank for injecting compressed air with sufficient kinetic energy into said filter in said first filtering compartment to help clean said first filter in said first filtering compartment; a first discharge outlet conduit connected to said first filtering compartment for discharging said filtered first portion of said partially dedusted gas stream from said first filtering compartment; said second filtering compartment positioned generally along side and spaced laterally away from said solids-gas separation compartment and in offset relationship thereto, rather than in vertical alignment or completely above said solids-gas separation compartment, said second filtering compartment being spaced laterally away from said first filtering compartment rather in vertical alignment therewith, said second filtering compartment cooperating with said first filtering compartment and simultaneously filtering said partially dusted gas stream with said first filtering compartment, said second filtering compartment having at least one second filter for filtering a second portion of said partially dedusted gas stream, at least one second compressed air tank communicating with said second filtering compartments, and at least one second air injector operatively connected to said second compressed air tank for injecting compressed air with sufficient kinetic energy into said second filter in said second filtering compartment; a second discharge outlet conduit connected to said second filtering compartment for discharging said filtered second portion of said partially dedusted gas stream from said second filtering compartment; a hopper comprising a bin positioned below and supporting said solids-gas separating compartment and said first and second filtering compartments of said multiple filtering compartments, said bin having a collection compartment for receiving and collecting the removed large particulates of dust from said solids-gas separator and smaller particulates from said first and second filtering compartments; said bin being selected from the group consisting of a stationary bin, a moveable bin, a portable bin, an a towable bin; said first and second filtering compartments each defining an open bottom communicating with said bin for discharging filtered particulates from said first and second filtering compartments of said multiple filter compartments into said bin; and said open bottoms of said multiple filtering compartments providing passageways for upward flow of the partially dedusted gas stream from said solids-gas separating compartment upwardly through said multiple filtering compartments.
