Abstract
A dust separator including a cylindrical housing that is separated by a pair of spaced apart tube sheets into an upper incoming air distributor, an intermediate tube compartment and a lower settling chamber. Large diameter air permeable filter tubes are suspended between the tubes to conduct airborne particles and dust captured inside the tubes into the settling chamber. A dirty air inlet is provided in the distributor while an air outlet connected to a blower is mounted in the lower part of the tube compartment. The blower draws air from the distributor through the tube walls so that the air is cleansed of airborne materials. A perforated control baffle is placed in front of the discharge opening to provide for a uniform and even flow of air through the tubes.
Claims18
Apparatus for separating particulate materials having a high concentration of dust from an air stream that includes a cylindrical vertically disposed housing having an air distributor in the top section thereof, a settling chamber in the bottom section thereof and a tube compartment between the distributor and the settling chamber, an upper tube sheet separating the distributor from the tube compartment, a lower tube sheet separating the settling chamber from the tube compartment, a series of air permeable filter tubes connected between the tube sheets, air inlet means connected to the distributor for admitting air containing a particulate material into the housing, an air discharge opening in the lower part of the bag compartment that is connected to a blower means for drawing air from the distributor through the walls of the air permeable tubes whereby air entrained materials are captured on the inside of the tubes and directed downwardly into the settling chamber, and a perforated flow-control baffle mounted in front of the air discharge opening so that a portion of the discharge air passes through the perforations and the remainder passes around the baffle.
Apparatus for separating fine particulate material from entraining gas stream that includes a vertical housing having an upper distributor, a lower settling chamber and a tube compartment situated therebetween, an upper tube sheet separating the distributor from the tube compartment, a lower tube sheet separating the settling chamber from the tube compartment, gas permeable filter tubes extending between the tube sheets, gas inlet means connected to the distributor for admitting gas containing fine particulate material into the housing, a gas discharge means located in the lower part of the tube compartment that is connected to a blower means for drawing gas from the distributor through the walls of the gas permeable tubes whereby particulate material is captured inside the tubes and directed downwardly into the settling chamber, control means for distributing the flow gas moving through the housing uniformly through the tubes said control means having a perforated baffle mounted in spaced apart relationship in front of the gas discharge opening, whereby part of the discharge flow passes through the perforations and the remainder passes around the baffle.
