Collard ABSTRACT: An antipollution device for removing the smoke particles from exhaust gases of an incinerator or fuel burning apparatus, having a plurality of upwardly directed steam jets mounted against the walls of the chimney adjacent to its opening and supplied with steam under pressure produced by an independent source such as a steam generator. As an incinerator, the apparatus also utilizes a gas burner for igniting the refuse articles, and an air blower having an air jet manifold for maintaining a high temperature of combustion within the incinerator. The apparatus also includes a control panel connected to a temperature sensing device for operating the gas burner, and air blower to maintain a high temperature of combusu'on within its combustion chamber.

ANTI-POLLUTION INCINERATOR The present invention relates to an incinerator for commercial and industrial use which significantly reduces air pollution during the incineration of refuse articles.

More specifically, the present invention relates to an improved incinerator having a smoke precipitator at its exhaust outlet for removing smoke pollutants from the air.

Most air pollution devices which are connected to the chimneys of incinerators consist of spraying a stream of water onto the emerging smoke particles to precipitate the smoke from the exhaust gases. Other incinerators utilize fluid filter tanks whereby the smoke is scrubbed by a bath of fluids, such as water, before being exhausted. These conventional smoke precipitating devices suffer from the disadvantage in that they are not very effective in removing smoke pollutants from the exhaust gases and further require a complexity of unreliable equipment in order to remove pollutants from exhaust gases.

The present invention overcomes many of the above described disadvantages of conventional smoke precipitating devices by utilizing a plurality of steam jetsto scrub the exhaust gases as they emerge from the incinerator chimney. The steam is supplied by either an independent steam generator, or from a steam source which is used for heating the building which contains the incinerator apparatus. The incinerator is also provided with both a gas burner and air manifold to start and maintain the incineration of the refuse articles. The incinerator also includes a timeclock connected in a controllable panel for automatically operating the incinerator at preselected times, and a temperature control for regulating temperature during incineration.

The smoke particles which are precipitated from the exhaust gases of the incinerator according to the invention are collected at the base of the incinerator along with the ashes, and disposed of periodically.

it is therefore an object according to the present invention to provide an incinerator having an improved smoke precipitation apparatus for removing a substantial amount of the smoke particles from the exhaust gases.

It is another object according to the present invention to provide an improved incinerator which scrubs the exhaust gases emerging from the outlet of the chimney by means of a plurality of upwardly directed steam jets.

It is another object according to the present invention to provide a commercial and industrial apparatus for removing pollutants from the air which is simple in design, easy to construct, and reliable in operation.

Other objects and features of the present invention will become apparent from the following detailed description considered in connection with the accompanying drawing, which discloses an embodiment of the present invention. It should be understood however, that the drawing is designed for the purpose of illustration only, and not as a definition of the limits of the invention, as to which reference should be made to the appended claims.

in the drawing wherein similar reference characters denote similar elements throughout the main figure:

The FIG. of the drawing discloses partly in cross section, the

- smoke precipitating apparatus according to the invention.

Referring to the drawing, there is shown a steam generator 10, having a temperature control 11, connected to its boiler,

, and a steam safety valve 12 for relieving excessively high pressures. Generator also includes a water inlet 13 regulated by valve 14 for supplying the boiler of the generator with a supply of water. The outlet 15 of generator 10 is connected through valve 16 to a T-connection 19. T-connection 19 permits steam generated by the heating system of the building containing the apparatus of the invention to be supplied by line 17, through valve 18, into T-connection 19. The outlet of T-connection 19 is connected through line 20 to T-connection 23. The steam may be tapped ofi' the bottom of T-connection 23 by opening valve 21 leading to line 22. The output of T-connection 23 is connected to line 24 for conducting the steam to T-connec- 25, which are mounted vertically along walls 31 of the incinerator, and include a plurality of steam jets 27 communicatively mounted into pipes 25 and directed upwardly at an angle of approximately 45. With valves 18 and 21 maintained in a closed position, and with valve 16 open, steam produced by generator 10 and directed through pipes 15, 20, 24, and 25 will be directed out of jets 27, and upwardly toward a rectangularly-shaped screen cage 30 which collects the smoke emerging from chimney 31. The smoke will spread throughout the area of the rectangular cage 30 before emerging through the screen so that the steam emerging from jets 27 will have sufficient opportunity to saturate the smoke particles. The smoke particles 45 will precipitate upon contact with the condensed steam, and drop down chimney 31 as shown in the direction of arrow 47.

The incinerator is connected at the base of chimney 31, and includes slanted wall 39 connected to vertical wall 50, terminating at floor 44. The back wall 43, which rises from floor 44, is interrupted by a plurality of chutes 29, located at each floor of the building. Chutes 29 are provided with covers 28 which are hinged to the wall by means of hinges 32. Refuse articles may then be inserted into the incinerator by opening covers 28, and dropping them through chutes 29, into the interior of the incinerator. The incinerator also includes a shelf consisting of a grate 41, an inclined member 40 connected to the extending end of grate 41, and a step 42 joining incline member 40 towall 43. Disposed above grate 41 is a gas burner 33 having a norzle 34 directed through wall 50, for incinerating the refuse articles which gather on top of grate 41. As an alternate heating supply, the incinerator also includes an air pump 35 connected to a manifold 36 which is directed through wall 50, and includes the plurality of air jets 37 directed over gas burner 33 toward grate 41.

The air directed through jets 37 onto the burning refuse supported by grate 41 significantly increases the combustion temperature of the articles being incinerated. The increased temperature of combustion cuts down i significantly on the amount of smoke which will be produced by the burning refuse in order to reduce the air pollution of the exhaust gases emerging from chimney 31. The incinerator of the invention is also provided with a temperature regulator 38 which maintains the temperature at or below 1600 F. within the combustion chamber of the incinerator. A control panel 51 is also provided connected to temperature control 38 by means of conductor 52. Control panel 51 is further connected to air pump 35 by means of connector 53, and to gas burner 33 by means of conductor 54. Temperature signals transmitted by temperature control 38 will cause control panel 51 to shut off air pump 35 and/or gas burner 33, if the temperature of the incinerated articles increases above 1600" F. In a similar manner control panel 51 will also maintain gas burner 33 and air pump 35 turned on in the event the temperature of the combustion chamber of the incinerator decreases to a predetermined low temperature.

Control panel 51 is also connected through conductor 55 to steam generator 10, and regulates the amount of steam supplied to steam jets 27 in accordance with the temperature of the combustion chamber.

Although the present invention has been described for use with incinerators, it is also obvious that it is equally adaptable for use with oil and coal burning equipment, commonly em ployed by heating and-electrical generating plants. in this embodiment, the coal or oil burning equipment will be located in the combustion chamber of the incinerator together with the boiler so that the steam jets which are mounted at the outlet of the chimney will be directly upon the smoke particles from the exhaust gases.

While only a single embodiment of the present invention has been shown and described, it will be understood that many changes and modifications may be made thereunto without departing from the spirit and scope of the invention as defined by the appended claims.
