Definitions

  • the invention relates to mechanism for removing dust contained in gases and more particularly dust carried along in the smoke from a furnace.
  • My invention consists of a combination of instrumentalities, which 'in practice have been found to be highly successful.
  • Figs. 1 and 2 are vertical sections on planes at right angles to each other;
  • Fig. 3 is a plan view in section along line 3-3 of Fig. l.
  • a centrifugal blower a has inlets ai, a1 at its two ends for the gas coming through the foot b1, of a stack, the upper part of which is shown at b.
  • I'he casing c of the blower is of the usual snail type and is placed within the wall of the stack b b1. Ordinarily the casings of such blowers extend about one revolution of a spiral, to about the point d.
  • the casing proper of the blower is extended by extension e which conducts the gas around the casing c and up through a pipe f to the upper part b of the stack.
  • the dust in the gas by reason of the centrifugai movement induced by the blower a, is pro- :lected to the periphery of the casing and is carried beyond the point d and down into the extension e.
  • such an extension of thecasing hasbeenshapedandused asacatch box for the dust (from which it is removed at intervals).
  • the gyratory motion is obtained by ⁇ directing the pipe i tan'- -gentially to the periphery of the cyclone k. the opening of said pipe into the latter being shown at a behind the plane of Figure 1 .l .
  • the top of the cyclone k opens at h into the f oot ln of the open into said foot b1, the-blower withdraws the gas from the cyclone k through h, in and o1, and
  • a cyclone or gyration chamber has already been employed i'orseparating dust but not in combination with a centrifugal blower having an outlet directed to a cyclone adapted to cause gyration about a vertical axis. It is also known to allow dust to pass from the periphery of a centrifugal blower into a settling chamber, but the latter has not been formed as a cyclone or vertical gyration chamber, the extension not having been led tangentially to the periphery of such a settling chamber.
  • What I claim isz- 1. The combination with a smoke stack of a centrifugal blower enclosed in a casing within the stack with inlets communicating with the lower portion of the stack and with a main outlet leading to the upper part of the stack, of a centrifugal dust separator having a tangential inlet in communication with a small outlet through the casing of the blower and having its gas outlet communicating with the inlet of the blower so that the blower exerts a suction and causes the dust-laden gas to ilow through the separator with sufiicient velocity and centrifugal eect to separate the dust.
