Definitions
- Temperature control device for surface-treated objects such as vehicle parts
- the invention relates to a tempering device for surface-treated objects such as vehicle parts, with a tempering, in which a surface-treated object is tempered, a high boiler exhaust air stream with high-boiling organic compounds from the temperature control and a combustion device for the thermal aftertreatment of the high boiler exhaust air stream.
- the invention relates to a method for tempering a surface-treated article with such a tempering device.
- tempering is understood here to mean the effect of a temperature change of an object, which may be an increase in temperature or a reduction in temperature, and in particular an evaporation process falls under such a temperature change process Solvent under, for example, slightly elevated room temperature.
- Exhaust air is understood to mean the exhaust air taken from the temperature control room, which is loaded with organic compounds, for example due to a temperature control process taking place in the temperature control room.
- organic compounds mentioned in the introduction reach the ambient air.
- These organic compounds can be dispensed from the painted article to the ambient air, for example, during an evaporation process after a painting process or during a drying process subsequent to the painting process. They usually have different boiling points. Some of the organic compounds boil below a temperature of 200 ° C and thus represents solvents or solvents in the narrower sense. This part is referred to herein as Niedersieder and is often already released at room temperature.
- Another part of the organic compounds boils only in the range of this temperature of 200 ° C, for example between 150 ° C and 220 ° C, or above. This part is often only released during drying processes at the appropriate temperature and is referred to herein as high boilers.
- the high boiler exhaust air flow is not accessible due to the aforementioned problems of a regenerative afterburning and can not be mixed with the low boiler exhaust air stream.
- the temperature of the high boiler exhaust air stream would be below the boiling point of the high boiling organic Compounds fall and the high boiler components contained would, as already indicated, condense. Consequently, the high-boiler exhaust air flow with higher energy consumption must be supplied to a thermal afterburning.
- a particular disadvantage of this solution is that two separate exhaust air treatment plants for the two different exhaust air streams must be maintained, which increases the design effort, maintenance and thus the financial burden of the entire tempering disadvantageously.
- the tempering device according to the invention for surface-treated articles such as vehicle parts has a tempering space in which a surface-treated object can be tempered, a high-boiler exhaust air stream with high-boiling organic compounds from the temperature control chamber and a combustion device for the thermal after-treatment of the high-boiler exhaust air stream.
- a device for pyrolysis of the high-boiler exhaust air stream for such a temperature control device.
- chemical bonds are broken in the organic constituents contained in the exhaust air stream, thus splitting up larger molecules into smaller ones.
- the molecular mass decreases and the boiling point of the compounds contained falls within a desired range, which permits a mixture of the high boiler exhaust air stream after pyrolysis with the low boiler exhaust air fraction without undesired condensation processes. It is then Consequently, it is possible to supply both exhaust air streams to a common combustion device.
- Both exhaust air streams ie the low boiler exhaust air stream and the high boiler exhaust air stream, can each also contain small amounts of the other fraction.
- the high boiler exhaust air stream may have between 5% and 15% low boiler components.
- between 5% and 15% of high boiler components may be present in the low boiler exhaust air stream.
- the pyrolysis device is arranged between the temperature control chamber and the combustion device.
- a pyrolysis treatment and subsequently an introduction into the combustion device can take place.
- the high boiler exhaust air stream which can be supplied to the pyrolysis device preferably comprises organic compounds having a boiling point in a range of about 200 ° C., that is to say, for example, in a range from 150 ° C. to 200 ° C. These organic compounds are preferably free from drying coatings such as coatings, if they are at a significantly elevated air temperature in a range of 200 ° C, that is, for example, at a temperature of 150 ° C - 220 ° C, dried.
- the low boiler exhaust air stream with low-boiling organic compounds has a boiling point below 200 ° C
- the low boiler exhaust air stream of the combustion device for thermal treatment, especially a regenerative thermal treatment can be fed.
- the low boiler exhaust air stream may for example have a temperature of 40 ° C - 60 ° C.
- the high boiler exhaust air flow and the low boiler exhaust air flow can be removed from the temperature control chamber at different process stages.
- the low-boiler exhaust air stream in an evaporation zone and the high-boiler exhaust air stream in a drying zone can be removed.
- the combustion device is designed in an advantageous embodiment as regenerative thermal afterburning.
- the pyrolysis device has a preheating area and a reaction area.
- the preheating area serves for preheating the high-boiler exhaust air stream provided for the pyrolysis.
- the preheating region can be heated, for example, by means of heat of the reaction region. This has the advantage that the energy used for the pyrolysis can be used as waste heat for preheating the high-boiler exhaust air stream.
- a concrete embodiment of such a pyrolysis device may have a longitudinal axis along which the high boiler exhaust air stream flows during the pyrolysis and wherein the pyrolysis device has an air guide which is designed so that the high boiler exhaust air flow can flow into the pyrolysis device tangentially to this longitudinal axis.
- the tangential inflow of the high-boiler exhaust air flow can be carried out in particular in the preheating area. In the tangential inflow, a particularly good heat transfer between the preheating and the high-boiler exhaust air flow can take place.
- the preheating is at least partially formed as a hollow cylinder.
- the high boiler exhaust air flow within the hollow cylinder more precisely within the wall of the hollow cylinder, are performed.
- This shape allows a particularly good heat transfer between the inner surfaces of the preheating area and the high boiler exhaust air flow.
- the reaction area may be at least partially disposed within the hollow cylinder.
- the reaction region can be arranged within the passage of the hollow cylinder and thus enclosed by the preheating region. This causes additional thermal insulation and thus contributes to energy efficiency.
- a displacement body for influencing the flow velocity is arranged within the reaction space.
- the amount of heat transferred between the reaction area and the preheater area can be influenced.
- the reaction region can be heated by means of a burner.
- the burner may be formed, for example, as a gas lance and cause heating of the high boiler exhaust air by at least 50 ° C, preferably by 80 ° C, more preferably by 100 ° C-150 ° C.

- the exhaust air lines 24, 28 may each also be a plurality of exhaust air lines.
- the evaporation zone exhaust air line 24 connects the temperature control chamber 16 with a regenerative thermal afterburner 30, also referred to as RNV.
- the RNV 30 may for example be designed so that ceramic bodies are alternately supplied with the exhaust air 26 and with already purified clean air via a rotating Heilverteilsystem. In this way, the clean air heats the ceramic body, which then give the ge stored heat to the exhaust air 24. To achieve the necessary temperature a burner is provided.
- the high boiler exhaust air stream 26 is fed via the drying zone exhaust air line 28 to a pyrolysis device 32.
- the thus pyrolysed exhaust air stream 34 can then be fed together with the low boiler exhaust air stream 22 of the RNV 30.

- the housing 35 is provided on its outside with a thermal insulation 38 and has in the interior a arranged along the longitudinal axis A reaction tube 43.
- the high-boiler exhaust air 26 After the high-boiler exhaust air 26 has entered the exhaust air supply line 36, the high-boiler exhaust air 26 is located in a hollow-cylindrical preheating region 40 which, to a certain extent, surrounds an outflow region 42 of the reaction pipe 43 as the preheating region annular gap 41.
- Heat is transferred from the outflow region 42 located in the interior of the reaction tube 43 into the preheating region 40 surrounding the reaction tube 43 via the annular gap 41, so that this region can be referred to as the heat exchanger region 44.
- the reaction area annular gap 48 is located between the reaction tube 43 and the housing 35 and connects to the preheating area 40.
- the reaction region annular gap 48 surrounds the actual reaction region 50 located in the interior of the reaction tube 43.

- the process gas discharge line 37 connects.
- the high-boiler exhaust air 26 enters the preheating region annular gap 41 of the preheating region 40 via the exhaust air supply line 36, which is here formed, for example, as an inlet connection 39. Due to the formation of the preheating region 40 as a hollow cylinder or annular gap, the exhaust air 26 charged with high boilers is twisted, which leads to an intensive surface contact of the exhaust air 26 with the outer surface of the reaction tube 43.
- the reaction tube 43 in particular in the outflow region 42, located and already pyrolyzed exhaust air 34 gives off a portion of their heat to the high-boiler exhaust air 26 and heats this example, by about 100 ° C. This means that a high boiler exhaust air flowing in at 200 ° C.
- the high-boiler exhaust air 26 is heated to the entry into the reaction region 50 via the Einströmweg 54 only slightly, for example by 20 ° C.
- the burner 56 provides an inflow of a hot fuel gas for heating the high boiler exhaust air 26 by 100 ° C-150 ° C, so that the exhaust air 26 is heated from the prevailing at entry temperature of for example 320 ° C, for example, 470 ° C. , At this temperature, as explained above, a pyrolysis of the high boiler Shares in the exhaust air 26 instead, so that the high boiler content, for example, reduced to ⁇ 5%.
- the process gas lingers for about 1 second in the reaction zone 50 and flows, for example, at a speed of 50 m / s.
