Definitions

  • the invention relates to an incineration plant for the efficient incineration of waste substances.
  • an incineration installation which comprises mainly a combustion chamber for the incineration of waste, a burner connected to the combustion chamber and intended to heat the air and the smoke gases in the combustion chamber, an evacuation chimney connected to the combustion chamber and intended for the evacuation of excess flue gases, an evacuation opening provided in the combustion chamber and intended for the evacuation of the residues of the incineration, and a means for the supply of fresh air into the combustion chamber, and, according to the main characteristic of the invention, in the combustion chamber several adjustable waste carriers are provided one above the other and at a certain distance from each other and which in the horizontal position carry the waste to be incinerated and in a different position reject the residues from the incineration and free the passage into the combustion chamber.
  • the cylindrical combustion chamber 1 in which the waste is thrown and burned and which is surrounded by a heating chamber 2, around which is placed an insulating jacket 3.
  • the combustion 1 is extended by an exhaust chimney 4 for the evacuation of excess flue gases.
  • a screen 5 Between this evacuation chimney and the upper part of the combustion chamber is provided a screen 5, which reduces the passage to the evacuation chimney.
  • a filling opening 6 Under this screen, in the combustion chamber 1 is provided a filling opening 6, through which the waste to be incinerated is thrown into the chamber combustion 1.
  • several tilting grids 8 or other waste carriers provided with a rotation axis 7 adjustable by 180 ° are suspended at equal distances from each other. Each axis is axially coupled to the axis of an electric motor 9 and is provided with a cam disc 10.
  • each grid 8 and in the combustion chamber 1 is placed an adjustable detector 11, a photoelectric cell, a thermometer, a camera or other measuring means, which controls the electric motor 9 of the grid 8 placed under detector 11 at the set times or temperature.
  • each detector 11 acts in concert with a switch 12 which controls the circuit 13 of the electric motor 9 connected to it.
  • the cam disc 10 mounted on the extended axis of the corresponding electric motor 9 is capable of triggering the switch 12 so that the circuit of the corresponding electric motor is cut.
  • each cam disc 10 The cams are fixed in such a way on each cam disc 10 that the current towards the corresponding electric motor is interrupted each time when the grid 8 which operates with it is rotated by 180 °.
  • the circuit 13 of each electric motor 9 is further additionally controlled by a manual switch 14.
  • the suction line 15 of a fan 16 At the upper end of the combustion chamber 1 is connected the suction line 15 of a fan 16, which can be switched on. by means of a manual switch 17 and the discharge line 18 of which is connected to the heating chamber 2.
  • air supply openings 19 are provided under each grid and on the outer mantle of this wall thermal ribs 20 are provided.
  • the fan 16 ensures the passage of the partially aspirated hot gases from the combustion chamber 1 to the reheating chamber 2, cooling the wall of the combustion chamber 1 slightly, these gases are additionally heated by the heat emitted by said thermal walls and ribs, and they pass back into the chamber combustion 1 via the air supply openings 19.
  • a burner 21 which is controlled by a manual switch 22 and which, through the opening 23 of the installation, sets fire to the waste and can preheat the installation beforehand.
  • the lower end of the combustion chamber 1 is provided with an opening 24 and a reel 25 capable of closing said opening and of collecting and evacuating the residues of incineration coming from the grates 8.
  • the switch 22 of the burner 21 is pushed, so that the burner preheats sufficiently, preferably up to 700 ° C. inside the combustion chamber 1.
  • the waste is thrown into the combustion chamber 1 and onto the upper grate 8, and this waste ignites immediately.
  • the switch 17 of the fan 6 is pushed, it is put into service and the hot gases which are located above in the combustion chamber 1 are partially evacuated by the evacuation pipe 4 and partially sucked by the fan to then be brought into the heating chamber 2 around the combustion chamber 1.
  • the red-heated wall of the combustion chamber 1 is slightly cooled, the gases deflected along are heated and again brought through the openings air supply 19 into the combustion chamber 1 for the best possible incineration of waste.
  • the temperature in the combustion chamber 1 can be appreciably high.
  • each layer of waste on fire will activate the combustion of the layer of waste immediately above, so that the waste is effectively burned and reduced to ashes.
  • the detector 11 located above the aforementioned grid and the switch 12 closes the circuit of the electric motor 9, which will rotate 180 ° until one of the cams of the cam disc 10 pushes the switch 12, whereby the circuit of the electric motor is interrupted, and this motor stops with its cam disc 10.
  • the residues of the incineration or ashes fall, while the said 180 ° tilting grid, on the reel 24 placed below, which in turn discharges the waste residues in a bin placed below.
  • the shape, the dimensions and the number of the component parts described above can differ and that some of these component parts can be replaced by others which have the same purpose.
  • the tilting grids can be replaced by other waste carriers which would be placed, for example, with a hinge or in a sliding manner in the combustion chamber.
  • one or more gas purifiers or electrostatic filters could be placed and that in the combustion chamber 1 one or more vessels in the shape of a drum could be placed for the incineration of sludge, chemical waste, agricultural waste and semi-liquid and liquid waste substances.
