Abstract
Organic materials being indirectly heated via hot air having the temperature required for their treatment, the process consists in the recycling of the vapours and gases evolving from the organic materials into a hot air circuit by forcing them into contact with the flame of a burner in order to burn the organic gases contained therein. The apparatus for executing the process comprises a double wall sealed tank; the outer wall being insulating and the inner wall being heat-conducting, the space, created by the walls, defines the hot air circuit.
Claims15
An apparatus for the thermal treatment of organic materials, said apparatus comprising:
- a. a tank having a bottom portion and comprising a inner wall made of heat conductive material and an outer wall made of insulating material, said inner wall and said outer wall defining a passage;
- b. a roof closing said tank and forming, with said inner wall, a treatment chamber adapted to receive organic materials;
- c. at least one access opening in communication with said chamber through which said organic materials can be introduced into said chamber;
- d. a burner opening into said passage and configured for sustaining a flame adapted to generate combustion gases, said combustion gases circulating through said passage for heating said organic material via said inner wall;
- e. a first conduit extending between said chamber and said burner for carrying gases evolving from said organic materials to said flame;
- f. a second conduit extending between said chamber and the exterior of said apparatus for introducing fresh air into said chamber;
- g. a mixer located inside said chamber;
- h. a heat exchanger connected to said passage and to said second conduit for transferring a portion of the heat of said combustion gases to said fresh air and to the ambient air inside said chamber, said heat exchanger being located inside said chamber.
A process for the thermal treatment of biologically contaminated organic materials, said process comprising the steps of:
- a. providing an apparatus adapted for the thermal treatment of organic materials, said apparatus comprising at least a tank, a burner and a temperature sensor;
- b. introducing a liquid inside said tank;
- c. preheating said apparatus with said burner;
- d. waiting until the inside of said tank reaches a biocidal temperature;
- e. introducing biologically contaminated organic materials inside said tank;
- f. thermally treating said biologically contaminated organic materials located inside said tank with said burner;
- g. recuperating gases and vapours evolving from said biologically contaminated organic materials under treatment;
- h. carrying said gases and said vapours to said burner for burning said gases and said vapours.
