Abstract

The particulate collector assembly 10 removes solid particulates from a gas stream. The assembly 10 includes an outer housing 12, an intermediate housing 40, and interior housing 54 to form therebetween a clean gas chamber t14, a particulate-laden gas chamber 41, and a particulate chamber. A plurality or cyclone separator units 62 cooperate with the chambers to remove particulates from the gas stream. Each separator unit is fixedly secured to the intermediate housing and extends radially inward through the inner housing 54. A plurality of cyclone supports 82 are secured to a radially inward end of the cyclone housings and are also secured to a center support pipe 90 within the particulate chamber. This arrangement forms a wagon wheel-like structure which provides the desired rigidity to prevent sagging of the cyclone separator units yet allows the assembly components to expand freely and uniformly to minimize stresses to avoid distortions when exposed to high operating temperatures.

Claims19

Dependent claims

A method of supporting a plurality of cyclone separator units within a particulate collector assembly for removing solid particulates from a gas stream, the plurality of cyclone separator units each having a cyclone unit inlet in fluid communication with a particulate-laden gas chamber, a cyclone unit outlet in fluid communication with a clean gas chamber, a particulate outlet in fluid communication with a particulate chamber, and each cyclone separator unit including a cyclone housing and a cone member within the cyclone housing, the method comprising:

forming an outer collector housing including a gas inlet for receiving particulate-laden gas and a gas outlet for discharging clean gas;
forming an intermediate housing supported within the outer housing, the intermediate housing and the outer housing defining the clean gas chamber therebetween in fluid communication with the gas outlet;
forming an inner housing supported within the intermediate housing, the inner housing and intermediate housing defining the particulate-laden gas chamber therebetween in fluid communication with the gas inlet;
forming the particulate chamber within the inner housing for receiving separated particulates;
providing a central support member within the particulate chamber;
arranging the plurality of cyclone separator units circumferentially about the central support member;
fixedly securing a radially outward portion of each cyclone housing to the intermediate housing, each cyclone housing extending radially inward through the inner housing;
and
fixedly securing a plurality of cyclone supports to a radially inward end of a respective cyclone housing and to the central support member.
