Abstract

A system for treating objects includes a device for tempering objects in which a tempering tunnel having at least one air outlet and at least one air inlet is arranged in a housing. At least one heating unit, in which a hot primary gas flow can be generated, is assigned to the tempering tunnel, wherein the hot primary gas can be guided into a circulating air heat exchanger, in which air from the tempering tunnel can be heated by hot primary gas as circulating air, which can be fed back to the tempering tunnel in a circuit via the at least one air inlet. The heating unit is coupled in the manner of a combined heating and power plant to an electric generator in such a way that electrical energy is produced during operation of the heating unit.

First claim

The invention claimed is:

1. Installation for treating objects comprising:
a) a device for temperature control of the objects, in which a temperature control tunnel is accommodated in a housing, the temperature control tunnel comprising at least one air outlet and at least one air inlet;
b) the temperature control tunnel being assigned at least one heating unit, in which a hot primary gas flow can be generated;
c) the hot primary gas being leadable into a circulating air heat exchanger, in which air from the temperature control tunnel can be heated by hot primary gas and can be fed back to the temperature control tunnel as circulating air in a circuit via the at least one air inlet,
d) a Sabatier reaction unit is provided, in which a Sabatier reaction can be carried out
wherein
e) the heating unit is coupled in the manner of a combined heat and power unit to an electric generator in such a way that electrical energy is generated during the operation of the heating unit, and
f) methane CH 4 produced in the Sabatier reaction unit is used to produce a combustible gas which is provided to a burner of the heating unit.

2. The installation for treating objects according to claim 1 , wherein means are provided, by means of which tunnel atmosphere can be sucked out of the temperature control tunnel as exhaust air.

3. The installation for treating objects according to claim 2 , wherein exhaust air can be supplied at least partly to a burner of the heating unit in the form of combustion air.

4. The installation for treating objects according to claim 3 , wherein a mixing unit is provided, by means of which the exhaust air can be enriched with oxygen O 2 .

5. The installation for treating objects according to claim 4 , wherein an electrolysis unit is provided, in which oxygen O 2 can be electrolytically produced and can be supplied to the mixing unit.

6. The installation for treating objects according to claim 5 , wherein electrical energy required for the electrolysis in the electrolysis unit is generated at least partly by the electric generator.

7. The installation for treating objects according to claim 6 , wherein
a) an electrolysis of water can be carried out by means of the electrolysis unit;
b) the electrolysis unit is linked to the Sabatier reaction unit;
c) hydrogen H 2 produced in the electrolysis of water being leadable to the Sabatier reaction unit and/or water H 2 O produced in the Sabatier process being leadable to the electrolysis unit.

8. The installation for treating objects according to claim 7 , wherein a carbon dioxide separator is provided, by means of which carbon dioxide CO 2 can be separated from exhaust gas of the heating unit and can be supplied to the Sabatier reaction unit.

9. The installation for treating objects according to claim 1 , wherein an ORC reactor is provided, in which an Organic Rankine Cycle can be performed, which is coupled to an electric generator in such a way that electrical energy is generated during the operation of the ORC reactor.

10. The installation for treating objects according to claim 9 , wherein the ORC reactor can be supplied with thermal energy via a heating fluid which can be led in a heating circuit through a heat exchanger, where the heating fluid absorbs waste heat of the heating unit which it releases again as thermal energy in the ORC reactor.

11. The installation for treating objects according to claim 9 , wherein the ORC reactor can be supplied with thermal energy via a heating fluid which is led through a heat exchanger, where the heating fluid absorbs heat from exhaust air from the temperature control tunnel which it releases again as thermal energy in the ORC reactor.

12. The installation for treating objects according to claim 2 , wherein the device for temperature control of the objects comprises a cooling tunnel which is cooled by means of an adsorption refrigerating device which can be supplied with thermal energy from the exhaust air of the temperature control tunnel via a heat exchanger circuit, for which exhaust air can be led through a heat exchanger of the heat exchanger circuit.

13. The installation for treating objects according to claim 1 , wherein the installation further comprises a device for coating objects.

14. The installation for treating objects according to claim 13 , wherein the installation comprises a pyrolysis device, in which combustible residual materials arising in the coating device can be pyrolysed, resulting in pyrolysis gas, and
pyrolysis gas can be supplied in the form of combustible gas at least partly to a burner of the heating unit.

15. The installation for treating objects according to claim 13 , wherein the coating device comprises an adsorption filter device, by means of which process air of the coating device can be filtered, a regeneration device being provided, by means of which exhaust air from the drying tunnel can be led through the adsorption filter device for the purpose of regeneration.
