Definitions

  • the present invention relates to incinerators and more particularly to a novel scrubber for use in incinerator systems which operates under control of automatic means and is substantially self-cleaning.
  • the primary concern of the present invention is the reduction of pollution in the air we breathe as a result of inefficient incinerators.
  • the invention provides a method and apparatus for scrubbing incinerator gases in an economical manner and having few moving parts so as to provide a high quality and yet simple and reliable structure.
  • the present invention is characterized by providing a system which effectively reduces particulate and other undesirable material from incinerator emissions, while doing so in a simple straightforward and highly reliable manner.
  • the present invention is comprised of barrier means within the exiting flue for constraining the emitted particulate bearing emission to flow in a tortuous path.
  • Automatic smoke detector means are provided in the neighborhood of the barrier for selectively energizing a water spraying device to emit a fine water spray upon a porous barrier, only in the presence of an emission.
  • the emission in passing through the porous barrier, is thoroughly washed, causing particulate to be removed therefrom through the combined cooperation of the porous material and the film of water sprayed upon one surface of the barrier. Particulate so removed from the emission is carried together with the water into a collection device where it may be simply and easily removed.
  • the water spray serves the further function of continuously washing the porous barrier so as to provide a substantially self-cleaning system.
  • FIGURE shows an incinerator system incorporating the principals of the present invention.
  • the incinerator system 10 may for example, be installed within a multifloor building such as an apartment house.
  • the drawing shows a schematic flow diagram of the progress of emissions from a primary combustion chamber provided in the lowest level thereof to the point where the emission enters into the atmosphere.
  • Occupants of the building may drop their waste and garbage into a chute-flue 1, through suitable hingedly mounted doors 17, which are preferably biased (by means not shown) to remain in a normally closed position.
  • the refuse drops downwardly, by gravity, into a primary combustion chamber 2 where the flames or heat source 2A, burns the refuse.
  • the charging flue gate 3 is moved to the closed position.
  • the combustion gases follow the path indicated by arrow A into a tortuous shaped secondary chamber 4.
  • the combustion gases pass a gas fired after burner 5, located within a portion of the tortuous shaped chamber, to burn and thereby reduce the fly ash content within the combustion emission.
  • the combustion gases continue substantially in the upward vertical direction, where they pass through a by-pass chamber section 6 and enter into the main flue 1.
  • the combustion gases continue to move vertically upward until they reach a barrier plate 8 which constrains the gases to move along a tortuous path as indicated by the arrows B.
  • An automatic smoke detector device 7 is located beneath the underside of barrier plate 8, so as to be directly in the path of movement of the combustion gases.
  • the smoke detector 7 is coupled to a water spray device, the connection being designated by phantom line 7a.
  • the water spray device has a spray head 9 whose valve (not shown) is operated under control of the smoke detector device so as to permit the passage of water through the valve mechanism and thereby emit a water spray 9a upon one surface of a porous barrier member 10.
  • the porous barrier member 10 may preferably be a screen, diagonally positioned within chamber 1 1, so as to cause any emissions directed toward the porous barrier to be constrained to pass therethrough.
  • Trough 12 is also further preferably inclined from one end to the other to cause the water collected therein to drop by gravity to its lower end through a downspout 12b, which is positioned above a liquid refuse container 13.
  • An overflow pipe 14 is positioned approximately half-way up the vertical side of the liquid refuse container 13 to permit the water reaching the intermediate level 13a to run off through pipe 14 and be collected within a second container 15 provided at a lower floor.
  • the wetted down pollutants are caused to settle at the bottom of container 13 and may be periodically collected therefrom.
  • the water film and screen jointly cooperate to remove the harmful components carried by the gaseous emission while at the same time providing a unique an rangement for self-cleaning of the system.
  • Apparatus for removal of particulate and other polluting material from an incinerator emission comprising:
  • a flue having an inlet and an outlet for carrying the combustion gases from its inlet, which gases are emitted from an incinerator, to the outlet thereof, whereby the emission may enter into the atmosphere;
  • a barrier plate being provided within said flue and extending from one wall of said enlarged chamber and aligned substantially transverse to the path of movement of exiting gases through said flue for causing exiting gases to move around said barrier plate;
  • porous barrier means positioned upon said barrier plate near the outlet end of said enlarged chamber, to occupy and fill the entire space defined by said outlet end and said barrier plate for constraining gaseous emissions passing therethrough in moving toward the outlet of said flue, said porous barrier means being aligned at an angle to the vertical direction;
