Definitions

  • ABSTRACT an incinerator system of the class including a lower tank for containing a liquid including apparatus for maintaining the liquid at a predetermined level, apparatus for supplying combustible scum containing material for flotation in a layer on the surface of the liquid; a medial ignition chamber mounted in fluid flow communication with the tank and having a burner device disposed therein; apparatus for supplying combustion air to the ignition chamber; an upper combustion chamber mounted in fluid flow communication with the ignition chamber and having apparatus for supplying combustion air to the combustion chamber; and a scrubber for receiving the products of combustion from the combustion chamber and discharging clean exhaust gas therefrom.
  • sewerage In view of todays so-called population explosion", the treatment of sewerage has become of the upmost importance. It will be appreciated that sewerage, by its very nature, presents difficult problems in the treatment thereof. It is oleaginous in character, whereby the solid material rises to the surface of the water, and when attempts are made to ignite these floatable combustibles, they are slow to ignite and it is difficult to obtain complete combustion. In view of the incomplete combustion, apparatus employed heretofore tended to discharge into the atmosphere particulate matter which, by todays standards, is intolerable. Related patents in this art include U.S. Pat. No. 3,356,622, issued Dec. 19, 1967; U.S. Pat. No. 2,194,136, issued Mar. 19, 1940; U.S. Pat. No. 2,537,467, issued Jan. 9, 1951; and U.S. Pat. No. 3,034,456, issued May 15, 1962.
  • this invention provides, in summary, an incinerator system characterized by an incinerator member having a lower tank portion for containing a liquid, means for maintaining the liquid in the lower tank portion at a predetermined level and means for supplying combustible scum containing material to the tank portion for flotation in a layer on the liquid.
  • a medial ignition chamber is mounted on the tank portion in fluid flow communication. This chamber contains burner means as well as means for supplying combustion air thereto.
  • An upper combustion chamber is mounted in fluid flow communication with the ignition chamber, and it also receives a supply of combustion air.
  • Conduit means are employed for transferring the products of combustion from the combustion chamber to a gas scrubber disposed adjacent the combustion chamber for cleaning be obvious herefrom or may be learned by practice with the invention, the same being realized and attained by means of the instrumentalities and combina tions pointed out in the appended claims.
  • the invention consists of novel parts, constructions, arrangements, combinations, methods and improvements herein shown and described.
  • FIG. 1 is a vertical sectional view showing the incinerator member portion of the incinerator system, constructed in accordance with the concepts of this invention.
  • FIG. 2 is a side elevation of the incinerator system, of the invention.
  • an incinerator system comprises an incinerator member 10 having a lower tank portion 12 mounted on a base plate 13, a medial ignition chamber 14 mounted in fluid flow communication with the tank portion, and an upper combustion chamber 16 mounted in fluid flow communication with the ignition chamber.
  • the lower tank 12 has an inlet 18 for receiving a continuous flow of oleaginous floatable materials contained in water from a sewer line, or the like.
  • the tank portion acts as a separator in which the floatable material is permitted to rise to the surface of the water below the ignition chamber.
  • There is a continuous flow of water Within the tank which discharges through an outlet 20 to an overflow conduit 22.
  • This conduit is substantially vertically disposed, and there is sufficient free flow communication with the tank 12 so that by maintaining a preselected water level in the conduit 22, as measured by an indicator 26, the same water level is maintained in the tank 12. It will be appreciated that by this means, accurate water level control can be maintained in the tank 12 in spite of the fact that the surface thereof is normally in a rather turbulent state for combustion purposes, as will be discussed more fully hereinafter.
  • a control valve 28, having a hand lever 30, serves to control the flow of water from the conduit 22 to a drain pipe 32, whereby controlling water level in the conduit 22, as well as in the tank 21.
  • Any suitable control valve may be employed, such as a Nichols level control valve, Model 100, as manufactured by the Nichols Engineering & Research Corporation, which is set by the hand lever 30 at an indicated water level 26 and will automatically discharge the necessary quantity of water into the drain 32 to maintain the so-selected water level.
  • a bypass valve 34 is interposed between the bottom of the conduit 22 and the drain 32.
  • the fioatable material or scrum rises in the tank 12 to the surface 40 of the water where it may constitute a thick layer.
  • This layer could be covered by ash after partial ignition and, thereby, tend to cake so as to prevent complete combustion.
  • This is prevented by agitating the scum by means of fingers 42 mounted on a transverse shaft 44, rotatably mounted on the tank, as at 46, and driven at a very slow rotational speed by means of a drive gear or pulley 48, driven by motor means 49, FIG. 2 provided for the purpose.
  • the floatable combustibles usually constitute only a small proportion of the liquid passing through the separator, and consequently the accumulation of such combustibles at the surface of the liquid is relatively slow, such as from about 12 hours to about 24 hours, for example.
  • ignition burners 50 which are angularly directed at an angle of about 45 towards said liquid surface and which burn oil or other suitable fuels.
  • a steel ring 59, FIG. 1 is mounted on gusset plates 61 to extend partly above and partly below the water level 40.
  • air jets 52 mounted around the periphery of the ignition chamber.
  • jets are supplied by way of an annular header 54 connected to an inlet 56 which, in turn, is connected to a distributing valve 58, FIG. 2, leading from a combustion air fan 60.
  • Secondary combustion air is supplied to the ignition chamber 14, as by means of jets 62, FIG. I, mounted around the periphery of the ignition chamber and supplied by an annular header 64, through an inlet 66, connected to the distributing valve 58, leading from the combustion air fan 60.
  • the jets 52 and 62 are directed tangentially, or at an angle with respect to the radius, for creating turbulence in the chamber.
  • the pressure of the secondary air is substantially lower than that of the primary air and, accordingly, such control is effected by means of manipulating the distributing valve 58, provided for the purpose.
  • the upper wall 70 of the ignition chamber is of shallow dome configuration and directs the products of combustion to a connecting passage 72 of substantially reduced diameter with respect to the diameter of the ignition chamber 14 and the combustion chamber 16.
  • a baffle 74 fabricated from refractory material, is mounted on the bottom of the combustion chamber 16, encompassing the upper end of the connecting passage 72 to thereby direct the products of combustion to enter the combustion chamber in a generally radial flow pattern.
  • the baffle forms an annular open-topped passage 76, with a shallow dishshaped lower wall, in the bottom of the combustion chamber.
  • Combustion air jets 78 mounted around the periphery of the combustion chamber, supply combustion air to the passage 76, preferably directed tangentially or at an angle with respect to the radius, to create sufficient turbulence to ensure substantially complete combustion.
  • the jets are supplied by an annular header 80, having an inlet 82 connected to the distributing valve 58, leading from the combustion air fan 60.
  • the distributing valve 58 is so-manipulated that the air flow through the jets 78 is maintained at such a volumn as to maintain a preselected temperature of the order of from about l200 to about l600F. in the combustion chamber 16, to ensure substantially complete combustion of the combustible material.
  • the combustion chamber 16 is provided with a generally shallow dome-shaped upper wall 84 leading to an outlet 86 or reduced diameter with respect to the diameter of the combustion chamber, for discharging the products of combustion.
  • the water tank portion 12 is preferably fabricated from a circular steel shell 88, FIG. 1, and the ignition chamber 14 and the combustion 16 includes a circular steel shell 90, lined with block insulation 92 which, in turn, is lined with refractory material 94.
  • the ignition chamber 14 and the combustion chamber 16 are fabricated as separate elements and fixedly connected to each other, as at 96. These chambers are provided with access doors 98 and 100, respectively, for maintaining, observation and the like purposes.
  • a discharge adaptor 102 is mounted on the outlet 86.
  • This adaptor is connected to a elbow 104, which is provided with a butterfly valve 106 to control the flow of combustion gases therethrough.
  • the elbow directs the gases downwardly into a quencher 108, which cools and increases the velocity of the moving gases.
  • Any suitable type of quencher may be employed such as the water spray injection type described in US. Pat. application Ser. No.
  • a transfer conduit 110 interconnects the quencher with an induced draft fan 112, that accelerates the flow of the cooled products of combustion into an entrance duct 114 at the foot of a cylindrical gas scrubber 116, which is of any suitable construction, such as that described in the aforementioned US. Pat. application Ser. No. 850,265, for example.
  • the gas scrubber has a lower outlet 118 for the discharge of particulate matter and an upper exhaust stack 120 for the discharge of pollution free exhaust gases.
