Definitions
- the present invention relates to an oven for Smoldering of solids, e.g. garbage, after the Preamble of claim 1.
- the object of the present invention is to provide an oven to create the type mentioned, in which the in the Heat contained in the burner gases as far as possible Treatment chamber or the material to be smoldered delivered can be and spread over the width of the Treatment chamber even heating even elongated Treatment chambers can be achieved.
- the measures according to the invention ensure that on the one hand, a significantly increased burner gas volume flow is feasible by the vortex chamber arrangement and that the Capacity through a corresponding widening of the Conveyor in the furnace can be increased.
- the oval or elliptical cross section results in a relatively larger one Width of the conveyor a more constant heat transfer into the treatment chamber and thus on what is to be smoldered Good.
- the burner gases are in the relatively short Vortex chamber arrangement heated and mixed intensively and can specialize in the flat chamber Spread constant heat transfer.
- the one in the drawing according to a preferred one Embodiment of the present invention shown oven 10 has an elongated furnace housing 11, which in usually along all walls with refractory Material, for example concrete, is bricked up.
- the furnace 10 is used for Smoldering of solids, e.g. garbage, in particular shredded form.
- a treatment chamber 12 which is also called Smoldering chamber is called for the smoldering of supplied crushed solids arranged.
- the Treatment chamber 12 is on the top of a ceiling 13 of the Furnace housing 11 and the underside of a conveyor 14 limited.
- the conveyor 14, which is near a floor 15 of the furnace housing 11 is arranged, has the shape of a circumferential band 16, not shown in detail, a deflection roller 17 in the region of the treatment chamber 12 and its other deflecting roller 18 outside of Treatment chamber 12, for example.
- Below a feed for the to smoldering solids is provided.
- Within the Treatment chamber 12 is between the conveyor 14 and the ceiling 13 of the furnace housing 11 a device 50 for Guide the burner gases in the furnace 10 provided.
- the device 50 for guiding the burner gases in the Burning furnace 10 has a swirl chamber arrangement 51 and an associated flat chamber 21, both within the treatment chamber 12 are arranged. Both the Vortex chamber arrangement 51 as well as the flat chamber 21 run across essentially the entire width of the Treatment chamber 12 or the conveyor 14. In Direction of the longitudinal extent of the treatment chamber 12 takes the vortex chamber arrangement 51 has a smaller length section a as the flat chamber 21. Ex. takes the Vortex chamber assembly 51 approximately 1/4 to 1/3 the length of the Treatment chamber 12 a while the remaining length of the Treatment chamber 12 is occupied by the flat chamber 21. In addition, the swirl chamber arrangement 51 has approximately the three up to four times the height of the flat chamber 21 Furnace housing 11 adapted to these different heights. In other words, the furnace housing 11 has in the area of Vortex chamber arrangement 51 a step-like increase.
- the swirl chamber arrangement 51 is essentially composed of an im Cross-section oval outer jacket 52 and one for this concentric also essentially oval inner jacket 53 formed.
- the outer jacket 52 and the inner jacket 53 has an elliptical shape instead of the oval one have and / or be arranged eccentrically to each other.
- the burner gases are essentially oval (or elliptical) annular outer space 54 and within the Inner shell 53 is essentially oval in cross section (or elliptical) interior 55 is formed.
- the circumference closed outer jacket 52 and the circumferential side closed inner jacket 53 are at one axial end a wall 56 closed.
- This end wall 56 has a radial area, a cylindrical opening to which axially outwardly penetrating the furnace housing 11 ⁇ bgasrohr 57 connects that exclusively with the interior 55 communicates.
- the other axial end of Outer jacket 52 and inner jacket 53 is also one Wall 58 covered on two spaced apart arranged radial areas with one each cylindrical opening 61 and 62 is provided, of which the one in the interior 55 and the other in the exterior 54 the vortex chamber arrangement 51 opens. Both cylindrical Openings 61 and 62 are on the swirl chamber assembly 51 facing away from the flat chamber 21.
- a burner chamber 63 which is not in illustrated way with a burner for oil or gas is equipped.
- the burner chamber 63 has a feed opening 65 for from the treatment chamber 12 coming fuel or smoldering gases.
- the tangential arrangement of the supply of the combustion chamber 63 in the The outer space 54 of the swirl chamber arrangement 51 lies according to FIG. 3 in the lower area between oval outer jacket 52 and Inner jacket 53.
- Burner tube 66 which is not shown in detail is also equipped with a burner for oil or gas.
- the outer space 54 of the swirl chamber arrangement 51 has a Guide helix 71, which is at an axial distance of the wall 56 in the region of the tangential mouth of the Combustion chamber 63 begins and extends to the other wall 58 extends helically so that the combustion chamber 63 gases flowing in tangentially helically in the outer space 54 are guided up to the cylindrical opening 62, the Burner gases on the burner tube 66 for repeated and further Warming be carried out.
- the outer space 54 is within this helical path 72 with from the outer jacket 52 and / or from the inner jacket 53 to the inside protruding pegs 73 assembled.
- These swirl plates can be so long that they are only partially in lane 72 protrude, or so long that they extend from the outer jacket 52 to Extend inner shell 53 and are each attached there.
- the swirl plates 73 can have a certain geometric Arrangement or be provided arbitrarily, being preferably arranged obliquely or transversely to the direction of flow could be.
- the interior 55 within the inner shell 53 is equipped with baffle plates 74, which are radial extend and each to a radial side wall connect.
- the individual baffle plates 74 and 75 are in Distance alternately arranged in opposite directions, see above that the exhaust gas flow according to Figure 4 is a labyrinthine path 76 must go through.
- the baffle plates 74 and 75 run over the entire height of the interior 55 and in each case about 2/3 of the width of the interior 55.
- Within this Labyrinth-like track 76 are also vortex plates 77 provided, which are similar to the swirl plates 73 and can be arranged.
- the flat chamber 21, which is rectangular in cross section has two in the illustrated embodiment parallel channels 28, 29, one of which via the cylindrical opening 62 with the outer space 54 and the others through the cylindrical opening 61 with the interior 55 communicates. Both channels 28 and 29 are on their the end facing away from the vortex chamber arrangement 51 in one another Connection. According to Figure 2, the channels 28 and 29 are through an essentially flat upright partition 31 from each other Cut. It is understood that the partition 31 itself can be baffled or other measures for a chicanery-like and thus extended track for the Burner gases can be hit in the flat chamber 21.
- the passage of the gases through device 50 is as follows: The from the treatment chamber 12 in the manner mentioned Suction gases are extracted in the combustion chamber 63 by a Temperature from e.g. 450 ° Celsius to a temperature of 850 ° Celsius warmed and as burner gases in the outer space 54 of the Vortex chamber assembly 51 introduced.
- the burner gases are running along the helical path 72, are swirled there and in the area of the burner tube 66 again heated and through the opening 62 in one channel 28 of the flat chamber 21 guided.
- the from the channel 29 of the flat chamber 21st Recirculated exhaust gases pass through the cylindrical opening 61 in the interior 55 and are along the labyrinthine Lane 76 swirled and countercurrent to the burner gases in the Outside space 54 led to the exhaust pipe 57.
- the guidance of the solids to be smoldered on the Conveyor 14 takes place from the feed location 19 above the End of the conveyor 14 in the region of the circulation roller 18, so that the good to be smoldered in the area of the connection of the two channels 28 and 29 of the flat chamber 21 in the Furnace housing 11, as at a range of minimum temperature entry.
- the conveyor 14 arrives with the smoldering material below and along the flat chamber 21 in areas of the Treatment chamber 12, initially below the flat chamber 21 and then below the vortex chamber assembly 51, at the in Direction of travel seen end the maximum temperature is reached.
- the smoldering Solids via the deflection roller 17 below the Conveyor 14 returned to the entry end and there in not shown in a transport device brought.
