Definitions
- each recirculation and fresh air module is usually equipped with its own heating register.
- Direct heating converts electrical energy into thermal energy or heat by allowing the electrical current to flow through a resistive heating coil, a heating wire or similar.
- the thermal energy is transferred directly to the gas flow to be tempered, such as the circulating air flow or the fresh air flow, via heat conductors such as heating fins.
- the dryer exhaust air is cleaned independently of the dryer heating. Thermal processes are usually used to clean the solvent-containing and odorous exhaust air.
- Another disadvantage is that the total connected load of the individual electrical heating sources or heating registers is usually higher (by approx. 10%) than in the case of a central solution with only a single heating source.
- the treatment system comprises a treatment room which comprises several treatment room sections, each of which is assigned to one of several separate circulating air modules of the treatment system.
- the treatment system also comprises a heating system which comprises a self-contained heating gas duct, wherein several circulating air modules are coupled to the heating gas duct, in particular for heating the gas guided through the treatment room sections.
- the present invention is therefore based on the object of providing a treatment plant which enables sustainable operation.
- the treatment plant is in particular a drying plant for drying vehicle bodies.
- the treatment system comprises the following: at least one treatment room, which comprises one or more treatment room sections, wherein the at least one treatment room and/or the one or more treatment room sections are each assigned to one of several separate recirculation modules, and wherein each recirculation module is arranged to guide a separate, circulating gas flow; and a heat transfer system for indirectly heating the gas flows, which comprises a heating device, wherein it can optionally be provided that a) at least one recirculation module has a heat exchanger, by means of which the respective recirculation module is coupled to the heat transfer system; and/or b) several recirculation modules are integrated into one or more heating circuits, in particular heating gas circuits, which are coupled to the heat transfer system via a central heat exchanger.
- one or more heating gas circuits can be coupled to the central heat exchanger, into each of which one or more recirculation modules can be integrated.
- the heat transfer system comprises: a closed heat transfer circuit which has at least one flow line and at least one return line and in which a heat transfer medium, in particular a liquid heat transfer medium, circulates.
- the heating circuit carries a heating gas or another heat transfer medium to which heat energy from the heat transfer system has been transferred.
- this is mixed directly into the gas streams circulating in the recirculation modules, whereas in the case of another heat transfer medium
- the heating device is preferably installed centrally (e.g. in a non-explosive location) and the heat is supplied to individual consumers, such as recirculation and/or fresh gas modules, via a branched pipe network using the heat transfer medium or the heating gas.
- the heat transfer medium can be solid, liquid or gaseous.
- the aim is to keep the thermal oil temperature as low as possible in order to avoid the formation of low-boiling components (decomposition of the hydrocarbon chains into smaller fragments).
- decomposition results in a reduction in the flash point and increases the risk of the formation of an ignitable mixture on the one hand and the tendency to cavitation on the other, which can lead to increased wear on system components (e.g. pumps). If you avoid reaching the so-called film temperature of the thermal oil, you will promote or at least maintain the longevity of the oil.
- thermal oil also has a higher specific heat capacity and a higher density, which means that the pipe cross-sections of the heat transfer circuit can be significantly reduced compared to hot air ducts. Significantly smaller pipe cross-sections also mean significantly lower surface heat losses. Integration into existing systems is therefore easier.
- the central installation of the heating device has the advantage, particularly compared to the decentralized heating mentioned above, that a heat source can be easily replaced or several different heat sources can be kept in parallel. This option is particularly advantageous in times of the energy transition, as many operators cannot yet foresee which form of energy will be the energy of the future for their location.
- the central installation enables the heating device to be easily and gradually expanded.
- the advantage is that smaller cable cross-sections and lower cable losses can be achieved compared to low voltage. Savings can also be made if the center station cannot be set up in the immediate vicinity of the heating device and thus the lower costs for the cabling and the transformer center station more than compensate for the remaining costs (e.g. additional costs on the heater side).
- the transformation effort is reduced or the transformer center station can be saved if the electrical heating register can be operated directly at the medium voltage level of the system network. Compared to low voltage, however, A more complex medium-voltage technology on the heater side with the corresponding costs is required.
- the gas-fired boiler is preferably used so that in the event of an increased power requirement when heating the cold treatment plant compared to the required production or operating output, an unnecessary electrical power installation can be dispensed with by providing the difference in power compared to the electrically provided operating power with a gas-fired boiler.
- concentrating solar thermal energy can be used as additional solar thermal heating for system heating in sunny locations with a high direct solar share.
- Fresnel collectors installed on the roof of the treatment plant can be integrated into the thermal oil circuit either directly or by means of a heat exchanger.
- the first approach of direct integration would have the advantage that the thermal oil circuit already provided could be used for solar thermal energy.
- the heating device can be operated using pure hydrogen heating or in a hybrid mode.
- the installed electrical power is preferably reduced by a hydrogen-assisted heating operation of the treatment plant,
- the demand for hydrogen can be covered with a hydrogen tank.
- Hydrogen heating offers the possibility of a CC>2-neutral operation of the system.
- the pipes are welded and are therefore permanently technically tight.
- a certain number of weld seams are regularly X-rayed and all threaded and flange connections must be checked regularly. It is advisable to implement hydrogen detection using one or more sensors and connect these to a gas warning system, which means that, for example, solenoid valves can switch off or block corresponding areas or sections in the event of an alarm.
- Outdoor installation is made possible by the fact that the thermal energy generated by the hydrogen-powered boiler or the hydrogen-powered central heating unit is transferred to the heating gas circuit via the heat carrier circuit and the central heat exchanger, whereby the central heat exchanger is preferably arranged within the building or hall of the treatment plant.
- the aforementioned heating gas circuit with a gaseous heat transfer medium is then suitable for heat distribution in the treatment plant area, whereby the heat supply to the recirculation modules is achieved by adding the heating gas.
- no heat exchangers are required in the recirculation modules, instead so-called mixing flaps are required to control and/or regulate the supplied heating gas volume flow.
- the return of the heating gas circuit to the central heat exchanger can also be designed as a simple return channel; preferably within the treatment room or the dryer tunnel ("triangular channel" in the rear wall-ceiling area), which means that there are almost no surface heat losses.
- the central heat exchanger is preferably located close to the treatment plant. This reduces the risk of the plant being contaminated with thermal oil and, as a result, significantly reduces the fire load. In other words, locating the central heat exchanger at the treatment plant means that fewer pipes need to be provided or shorter pipes can be laid, which reduces the total circulating volume of thermal oil and, in the event of an accident, also reduces the fire load.
- the heating device can already provide two or more different heat sources, so that depending on the
- the aim is to achieve the lowest possible exhaust gas temperature, which is achieved, among other things, by a heat exchanger downstream of the exhaust gas purification device, which further cools down the exhaust gas discharged from the treatment plant in order to utilize the calorific value effect.
- the boilers preferably require a minimum exhaust gas temperature in order to avoid condensation phenomena.
- the heating gas circuit comprises the following: at least one electrical heating device for heating the heating gas, at least one mixing device which is arranged downstream of the at least one electrical heating device, and at least one heat storage unit for storing and releasing heat, wherein the at least one heat storage unit is fluidly connected to the at least one mixing device.
- the intermediate buffering of the heat in the at least one heat storage unit of the heating gas circuit is preferably carried out by storing the heat during the weekend or during production breaks.
- the stored heat can thus be accessed in parallel with the heat provided or generated by the electric heating device when the treatment plant has to be heated up to operating temperature or when more heat is required during production peaks.
- heat storage units form a heat storage unit, wherein it is advantageous if the heat storage units can be individually charged or discharged with heat.
- the mixing device is designed such that heating gas heated in the electric heating device can be fed to the heat exchanger, or to the at least one heat storage unit for storing at least a portion of the heat contained in the heating gas, or to the heat exchanger with the addition of at least a portion of the heat stored in the at least one heat storage unit.
- the mixing device advantageously has at least three switching positions, via which the heating gas flow can preferably be directed.
- the heat generated from electrical energy in the at least one heating device is stored in the at least one heat storage unit at times when electricity prices are low and, conversely, stored when electricity prices are high. It is therefore advantageous if the control variable in this context is the electricity price. By storing heat generated from electrical energy, it would also be possible to react to a power shortage or a power outage.
- the heat exchanger is preferably a gas-liquid heat exchanger, wherein to protect against the entrainment of liquid or heat transfer medium from the heat transfer circuit into the heating gas circuit, the heat exchanger preferably has a double wall and a liquid detection device between the inner and outer tubes.
- the heat transfer system comprises a pump device with at least one pump for conveying the heat transfer medium through the heat transfer circuit and at least part of the heating device.
- the at least one pump can be a circulation pump, for example. It is also conceivable that two or more pumps are operated in parallel.
- the treatment plant comprises an exhaust gas purification device, in particular an electrically thermal exhaust gas purification device, for cleaning exhaust air, which can be fed from the treatment room to the exhaust gas purification device via an exhaust gas duct, wherein the exhaust gas purification device leads clean gas obtained by cleaning out of the treatment plant via a clean gas duct.
- an exhaust gas purification device in particular an electrically thermal exhaust gas purification device, for cleaning exhaust air, which can be fed from the treatment room to the exhaust gas purification device via an exhaust gas duct, wherein the exhaust gas purification device leads clean gas obtained by cleaning out of the treatment plant via a clean gas duct.
- an electrical thermal exhaust gas purification device is preferably an exhaust gas purification device which also uses electrical energy from renewable energy sources.
- catalytic afterburning is known as an exhaust gas purification process. This process is also known as catalytic oxidation and is preferably used to reduce hydrocarbon emissions.
- the advantage over thermal afterburning is the lower reaction temperature. A reaction temperature of around 790 °C is required so that the exhaust air is sufficiently cleaned, although this temperature is essentially independent of whether an RTO or thermal afterburning is used.
- certain ingredients in the paint can act as catalyst poisons and clog the catalyst. The maintenance requirements of the system and the risk of failure can therefore be high.
- a thermal process is therefore preferable for cleaning the solvent-containing and odorous exhaust air.
- a thermal process enables autothermal operation using the heat energy released by the oxidation of solvents.
- a low clean gas temperature level is obtained following the post-combustion and the clean gas enthalpy can be used to preheat the fresh gas supplied to the system.
- the low Clean gas temperature is basically due to the design or construction of the exhaust air purification device and is therefore essentially not a characteristic of the actual solvent combustion.
- an electrical and thus flameless operated, regenerative-thermal single-bed exhaust air purification device which achieves a high energy efficiency, is preferred for the exhaust air purification device.
- the flow through the electrically heated bed is controlled and/or regulated using disk valves and switched cyclically.
- the core is preheated; a chemical reaction takes place without the addition of combustion gas, but with the addition of electrical energy.
- the gas then cools down on the other half of the bed.
- the already preheated fresh gas flow only needs to be brought to the final or target temperature of the inlet or outlet lock of the treatment room, for example with the help of another downstream heat exchanger such as a thermal oil-gas heat exchanger, which is coupled to the heat transfer medium circuit.
- another downstream heat exchanger such as a thermal oil-gas heat exchanger, which is coupled to the heat transfer medium circuit.
- a fan for conveying the exhaust air is arranged in the exhaust gas duct.
- the one or more heating circuits each comprise at least one heating flow and at least one heating return, and wherein heating gas can be fed into the at least one treatment chamber and can be fed out of the at least one treatment chamber by means of the heating circuit.
- the heating circuit either supplies heating gas directly into the treatment room or is used to heat the gas flow fed into the recirculation modules using a heat transfer medium, such as thermal oil.
- the thermal energy generated by the heating device is primarily provided by a hydrogen-based boiler or a hydrogen-based heating unit,
- the heat transfer system is designed as a compact device in which at least the heating device, the central heat exchanger and the heat transfer circuit are integrated.
- the pump device can also be integrated into the compact device.
- the heat source of the heating device is or comprises an electrical heating register, in particular an AC medium-voltage heating register.
- an AC medium voltage (1 to 35 kV)
- a liquid heat transfer medium must flow around the heating element to ensure that heat is dissipated at elevated temperatures and to avoid temperature hotspots. The same applies to other voltage ranges.
- the heat transfer circuit and the heating gas circuit are coupled to one another via the central heat exchanger for heat transfer.
- the treatment chamber has an inlet lock and/or an outlet lock, and wherein fresh gas can be supplied to the inlet lock and/or the outlet lock via a fresh gas supply.
- a fresh gas silhouette By supplying fresh gas into the locks, a fresh gas silhouette can be formed there, by means of which the atmosphere of the treatment room can be separated from the ambient atmosphere.
- At least one fresh gas module is arranged in the fresh gas supply, by means of which the supplied fresh gas can be tempered, in particular heated.
- Heating of the fresh gas is necessary to prevent condensation in the area of the locks, which could otherwise impair the workpiece treatment in the treatment room.
- a first fresh gas module is arranged in the fresh gas supply, by means of which at least part of the thermal energy of the clean gas can be transferred to the fresh gas, and that a second fresh gas module is arranged downstream of the first fresh gas module, by means of which the fresh gas can be heated to a target temperature.
- the second fresh gas module comprises an electric heating register and/or is coupled to the heat transfer medium circuit. Since treatment plants such as drying plants for vehicle bodies are usually equipped with an exhaust air cleaning device, it is advantageous to use the waste heat from the cleaning process by using the cleaned, hot clean gas enthalpy stream with the help of a heat exchanger to preheat the fresh gas or fresh air.
- the fresh air flow is already preheated and only needs to be brought to the final or target temperature for the inlet and/or outlet lock in a second step or stage.
- waste heat or the thermal energy contained in the cleaned clean gas is particularly suitable if the drying plant and the exhaust air purification device are not installed too far apart from each other.
- the drying system and the exhaust air purification device are installed too far apart from each other (for example, if the exhaust air purification system is outside the building and/or on a different system level), then preheating the fresh gas is not economically viable.
- the only preheating or heating stage used is a fresh gas module with a heat exchanger that is coupled to the heat transfer medium circuit, or an electric heating register contained in the fresh gas module to heat the fresh gas.
- each recirculation module is assigned at least one control and/or regulating device, in particular a 3-way control valve, for controlling and/or regulating the temperature of the gas flows guided by the recirculation modules, wherein the control and/or regulating devices are preferably arranged in the flow of the heat transfer medium circuit and/or in the heating gas flow of the heating gas circuit.
- the control and/or regulating device thus supplies the recirculation modules and, if applicable, the affected fresh gas module with the required amount of thermal oil or - in the case of a central heat exchanger - the recirculation modules with the required amount of heating gas, whereby the controlled variable is the recirculation air temperature in the treatment room or the treatment room sections.
- the heat exchanger of each treatment room section or each zone is designed according to the greater heating output in the operating or heating case.
- the control and/or regulating devices or control groups can now distribute the central, relatively constant electrical heating output of the heating device to the treatment room sections depending on the operating mode, whereby it must be taken into account that the necessary heating output in the operating and heating cases differ considerably from one another.
- each treatment chamber section is also assigned at least one control and/or regulating device, by means of which the respective volume flow of the heating gas returned to the central heat exchanger can be controlled and/or regulated.
- the process is used to treat workpieces, in particular to dry vehicle bodies.
- the procedure includes the following steps:
- the heating device has i) at least one exchangeable heat source; and/or ii) at least two different heat sources for parallel and/or alternating heating of the heat transfer medium.

- the heat transfer medium circuit 122 which has a flow line 128 and a return line 130, preferably carries a liquid heat transfer medium such as a thermal oil, water or an ionic liquid in a circuit.
- a thermal oil is preferably used as the heat transfer medium, ideally with a flow temperature of 250 °C and a return temperature of 230 °C.
- the heating device 124 further comprises an expansion tank (not shown) which is connected to the one or more heat sources 132 via a non-closable expansion line (not shown), whereby the heat transfer medium can expand.
- a nitrogen blanket ensures the required pressure equalization and a closure against an oxygen supply, which in the case of thermal oil as a heat transfer medium prevents oxidation of the thermal oil.
