Abstract
A bag house is mounted on a portable trailer and has a tube sheet with depending filter bags in part defining a first plenum for receiving a gas stream with fines and a second plenum for receiving clean gas from the filter bags. The fines are collected in one or more hoppers below the filter bags. A screw conveyor in each hopper has reverse flighting adjacent opposite ends for conveying separated fines longitudinally along and from adjacent opposite ends toward a central location intermediate the length of the housing. An elevation conveyor having an inlet located in the central location conveys the collected separated fines out of the housing to an external outlet for discharge into a surge operator.
Claims25
A bag house for removing fines from a gas stream, comprising:
- an elongated housing;
- a separator within the housing for separating fines from the gas stream, said separator including a fines filter separating first and second plenums one from the other respectively in part defining the gas stream with fines and a clean gas stream without fines on opposite sides of the filter;
- at least one fines collection hopper within said housing and extending longitudinally of said housing, said first plenum and said fines collection hopper lying in communication with one another enabling the fines collection hopper to receive the separated fines;
- a longitudinally extending collection conveyor for conveying the separated fines from adjacent opposite ends of said hopper and in opposite longitudinal directions along the hopper to a location intermediate the opposite ends of the hopper;
- and
- a longitudinally extending inclined elevating conveyor having an inlet within said housing adjacent said intermediate location for receiving the separated fines from the longitudinal extending collection conveyor and conveying the separated fines to an outlet elevated above said inlet for discharge from the housing.
A method of removing fines from a gas stream containing fines and supplied to a bag house, comprising the steps of:
- (a) providing an elongated housing having a separator within the housing having first and second plenums on opposite sides of a fines filter for separating the fines from the gas stream and providing an elongated hopper within the housing for collecting the separated fines received from said first plenum;
- (b) conveying the separated fines from adjacent opposite ends of said hopper and in opposite longitudinal directions along the hopper to a location intermediate the opposite ends of the hopper;
- (c) conveying the separated fines from said intermediate location to a location external to one end of the housing, the step of conveying including providing an elevating conveyor having an inlet within said housing at said intermediate location for conveying the separated fines to an elevated location external to said housing having an outlet for discharging the separated fines into the discharge hopper;
- and (d) discharging the separated fines adjacent said one end of the housing into a discharge hopper.
A bag house for removing fines from a gas stream, comprising:
- an elongated housing;
- an elongated separator within the housing for separating fines from the gas stream, said separator including a fines filter separating first and second plenums one from the other respectively in part defining the gas stream with fines and a clean gas stream without fines on opposite sides of the filter;
- at least one fines collection hopper within said housing and extending generally coextensively with the separator within the housing, said first plenum and said fines collection hopper lying in communication with one another enabling the fines collection hopper to receive the separated fines;
- a collection conveyor for conveying the separated fines from adjacent opposite ends of said hopper and in opposite directions along the hopper to a location intermediate the opposite ends of the hopper;
- and
- a fines removal conveyor within said housing having an inlet adjacent said intermediate location for receiving the separated fines from the collection conveyor and conveying the separated fines to an outlet external to said housing for discharge from the housing, said fines removal conveyor extending in an upwardly inclined direction from said inlet to said outlet.
A method of removing fines from a gas stream containing fines and supplied to a bag house, comprising the steps of:
- (a) providing an elongated housing having a separator within the housing having first and second plenums on opposite sides of a fines filter for separating the fines from the gas stream and providing an elongated hopper within the housing in communication with said first plenum for receiving and collecting the separated fines;
- (b) conveying the separated fines from adjacent opposite ends of said hopper and in opposite directions along the hopper to a location intermediate the opposite ends of the hopper;
- (c) conveying the separated fines from said intermediate location to a location external to the housing, the step of conveying including providing an elevating conveyor having an inlet within said housing at said intermediate location for conveying the separated fines to an elevated location external to said housing having an outlet for discharging the separated fines into the discharge hopper;
- and
- (d) discharging the separated fines from said location external to the housing into a discharge hopper.
