Definitions
- a device for securing heat exchangers is for example from the DE 30 05 212 A1 known.
- Contaminants may be in the form of solvents, for example, which may escape from surface coatings of the articles when they are dried in a dryer or provided with a lacquer or other coating.
- the proportion of the purified process air which is not used as circulating air, can be supplied as a hot primary gas of a device of the type mentioned for its thermal utilization.
- thermal utilization does not mean that the primary fluid must always have a higher temperature than the secondary fluid. Even if the primary fluid has a lower temperature than the secondary fluid and the secondary fluid in the heat exchanger device thus based on When a starting temperature is cooled, the primary fluid is used thermally. This is reflected in the term "tempering", as used in the beginning.
- the secondary fluid coming from the heat exchanger device is usually used in other process steps, which need not be related to the origin of the primary fluid.
- operating parameters of the waste heat utilization and of the secondary fluid are monitored in a manner known per se, since in the event of a fault, the flow of primary fluid to the heat exchanger unit must be safely interrupted.
- There are existing standards, which for this purpose require a shutdown of the afterburner for certain safety-relevant incidents to ensure that no hot primary gas is generated anymore.
- the treatment process in the treatment cabin then also has to be interrupted since the process air arising there can no longer be treated. This will be discussed again below.
- a low-energy closing valve exist in the inlet line to and in the outlet of the heat exchanger unit.
- Such a valve can be brought, for example, electromotively or fluidically in its open position, as it is known per se. Accordingly, resources necessary for the operation of such a valve include an electrical power supply, a fluid supply, or the like.
- valve By combining such a valve with the control system, it is ensured in the event of a malfunction that reliable prevention of primary fluid from passing to the heat exchanger unit or passing through the heat exchanger unit where it comes into thermal contact with the secondary fluid. In this case, however, the primary fluid can flow off via the flow line and be removed.
- valve unit is arranged in the inlet line of the heat exchanger device and is a first valve unit and, in addition, a second valve unit is arranged in the outlet line of the heat exchanger device. Then, primary fluid that has flowed past the heat exchanger device can be prevented from flowing back through the outlet pipe to the heat exchanger unit. Furthermore, this second valve unit can be regarded as a redundant safety valve in the case of increased safety requirements since the flow path of the primary fluid through the heat exchanger device is blocked by the second valve unit can be if the first valve unit should fail.
- operating means are also necessary for the operation of the second valve unit, and also the second valve unit is set up in such a way that it assumes its closed position in the absence of the operating means. This means that then the second valve unit is a low energy closing valve.
- the volume flow of the primary fluid through the heat exchanger device can be advantageously set if the control and regulating device comprises a fan whose operating power is adjustable.
- the fan may be arranged downstream or upstream of the heat exchanger device, it being favorable when the fan is arranged in the outlet line or the inlet line of the heat exchanger device.
- the fan is arranged downstream of the heat exchanger unit and preferably in the outlet line of the heat exchanger device, since in this way already cooled primary fluid reaches the fan and its thermal load is thereby reduced.
- outlet line of the heat exchanger device is combined with the flow line to form a collecting line.
- a chimney has a large flow cross-section with a predefined straight flow direction, so that primary fluid can be discharged through the chimney above the roof in the event of a malfunction without obstructions.
- FIG. 1 There is shown schematically a generally designated 10 system for the treatment of objects, as known from the prior art.
- the Appendix 10 includes in on and for a known manner, a treatment cabin 12, in which the objects are subjected to a treatment, and an air system 14, by means of which the air budget of the plant 10 and the treatment cabin 12 is controlled and regulated.
- the treatment of the articles may, as mentioned above, be a drying, coating or other treatment.
- process air is produced in the treatment cabin 12 which removes impurities, for example solvents, from the treatment cabin 12 and is supplied thereto by means of a blower 16 via a process air line 18 to a thermal or regenerative afterburning device 20.
- the impurities are burned by means of a burner 22 in a manner also known per se, whereby purified hot exhaust air is produced, which leaves the afterburner 20 via an exhaust air line 24.
- bypass line 26 which bypasses the post-combustion device 22 and downstream of the afterburner 22 into the exhaust duct 24, where merging through the bypass line 26 process air with the hot exhaust air.
- the throttle valves 28, 30 are controlled by a process controller 32, which is schematically indicated by dashed lines Arrows is indicated, which do not bear a special reference number.
- one of the two throttle valves 28, 30 can be dispensed with. If there is no bypass line 26, these throttle valves 28, 30 are dispensed with.
- the air flowing through the exhaust line after the discharge point of the bypass line 26 can thus be formed only by untreated process air, by a mixture of process air and exhaust air in almost any desired mixing ratio or only by hot exhaust air from the afterburner 22 , In the normal case, however, the entire process air is supplied to an afterburner, which is why usually only hot exhaust air from the afterburner 22 flows through the exhaust air line 24. This is assumed below for the sake of simplicity.
- the exhaust air duct 24 leads the exhaust air now in a system area 34 to a device 36, by means of which the hot exhaust air can be used thermally. There forks the exhaust pipe 24 in two lines 38, 40th
- the first line 38 forms an inlet line, via which the hot exhaust air can flow into a heat exchanger 42, where it is guided past a heat exchanger unit in the form of a heat exchanger coil 44 and thereafter flows out of the heat exchanger 42 via an outlet line 46.
- the hot exhaust air thus forms a primary fluid, which is why the hot exhaust air is hereinafter referred to as hot primary air.
- the second line 40 is a flow line through which this hot primary air can be fluidly routed past the heat exchanger 42, so that this primary air does not get to the heat exchanger 42.
- the flow line 40 is brought together downstream of the heat exchanger 42 with the outlet line 46 to a manifold 48, via which the primary air reaching there is now discharged at a lower temperature to a chimney 50 and from there via roof.
- a chimney defines a straight flow direction, as is well known in the art.
- filter stages can still be flowed through to free the primary air of impurities still present.
- a liquid secondary fluid is conveyed by means of a pump 52 through the heat exchanger coil 44, which receives heat from the hot primary air.
- the secondary fluid may be, for example, water or an oil, so that depending on the starting temperature of the hot primary air hot water, hot water or steam or correspondingly heated thermal oil can be generated, as it is known per se.
- a gas can also be used; in this case, a blower is provided instead of the pump 52.
- the respective proportion of the hot primary air flowing via the exhaust air line 24 into the system area 34, which is guided past the heat exchanger 42 or via the flow line 40 via the inlet line 38, is adjusted by means of two throttle valves, wherein a heat exchanger throttle valve 54 in FIG the inlet pipe 38 and a flow throttle valve 56 is arranged in the flow line 40.
- the throttle valves 54 and 56 can be controlled by means of a heat exchanger control 58, which is again illustrated by dashed arrows without their own reference numerals.
- throttle valves 54, 56 may - as well as throttle valves 28, 30 in connection with the post-combustion device 42 - for example, electromotive or fluid operable valves are used, as they are known per se.
- the resources such as an electrical power supply or a fluid supply necessary for the operation of these valves are provided by the heat exchanger controller 58.
- the throttle valve 54 and 56 thus form together with the heat exchanger control 58, a control device 60 through which the respective proportion of the primary air is adjustable, which passes into the heat exchanger device 42 and into the flow line 40.
- the operating parameters of the device 36 for the thermal utilization of the hot process air are also monitored in a manner known per se, as are operating parameters of the secondary fluid and, if appropriate, of system parts which use this secondary fluid.
- the determined monitoring data are transferred to a safety controller 62 of a safety device 64, which is outlined by a dashed double line.
- the safety controller 62 evaluates the operating parameters. In the event of a malfunction of a safety-relevant function, ie a so-called "Safety Instrumented Function", SIF for short, the inflow of hot primary air into the heat exchanger coil 44 must be completely and safely interrupted. For this purpose, it has established itself taking into account existing standards, such as the "Technical Rules for Steam Boilers", short TRD, the operation of the burner 22 to be on the safe side, so that certainly no hot primary gas is generated. In this case will the operation of the burner 22 is therefore interrupted by the safety controller 62. The control of the burner 22 by the safety controller 62 is again shown by a dashed arrow. As a result, the safety device 64 thus reduces the temperature of the primary air flow, whereby a secure state is achieved even in the event of a failure of the closing function or sealing function of the valve 54.
- a safety-relevant function ie a so-called "Safety Instrumented Function"
- SIF Safety Instrumented Function
- FIG. 2 shows now as the first inventive embodiment, a system 10, in which in the event of a fault in connection with the coming of the heat exchanger device 42 secondary fluid treatment process must not be interrupted.
- components that follow those of Appendix 10 FIG. 1 correspond, the same reference numerals.
- Appendix 10 shown comprises a modified apparatus for thermal utilization of the primary air, which carries the reference numeral 66. There is no valve disposed in the flow line 40.
- a valve unit in the form of a first safety valve 68 and additionally in the outlet line 46 a valve unit in the form of a second safety valve 70, which are covered by the safety device 64.
- the safety valves 68 and 70 are characterized in that, in the absence of resources, i. without supply of energy, be it electrically, fluidly or otherwise, assume a closed position and close the associated line 38 or 46 and completely block. In other words, the safety valves 68 and 70 are energy-free closing valve units.
- a fan 72 by means of which hot primary air from the exhaust air line 24 can be sucked into the heat exchanger 42, is arranged in the outlet line 46.
- the operating power of the blower 72 can be changed. In this way, the volume flow and thus the proportion of process air can be adjusted, which flows through the heat exchanger 42 and through the flow line 40.
- the fan 72 may also be disposed in the inlet conduit 38 of the heat exchanger 42.
- the safety valves 68, 70 may be designed as valves without throttling action.
- this spring-loaded flap valves are used with servomotor, which occupy their closed position without energy supply by the spring force and fully open when operating energy.
- the fan 72 can be dispensed with.
- the safety valves 68, 70 are designed as throttle valves, so that the volume flow of hot primary air to the heat exchanger coil 44 depending on the opening degree of the safety valves 68, 70 can be adjusted.
- throttle valves can also be used in conjunction with the fan 72.
- the safety valves 68 and 70 and the blower 72 are controlled by means of the heat exchanger control 58.
- the safety controller 62 is not in control connection with the burner 22 of the post-combustion device 20, but works directly with the heat exchanger controller 58 and so together with this forms a safety system through which the resources for the safety valves 68, 70 can be blocked.
- the safety controller 62 interrupts the power supply from the heat exchanger controller 58 to the safety valves 68 and 70 and to the blower 72.
- the safety controller 62 disables the resources for the safety valves 68 and 70 and the blower 72. This results in an immediate closure of both the inlet line 38 and the outlet line 46 of the heat exchanger 42 and to an immediate end of the conveying action of the blower 72nd
- the hot primary air from the exhaust air line 24 can thus flow only via the flow line 40 to the heat exchanger 42 over into the manifold 48 and from there into the chimney 50 and roof. Since the hot primary air through the post-combustion device 20 is purified air, this is also environmentally safe.
- the safety controller 62 may also communicate directly with the safety valves 68, 70 and with the fan 72, bypassing the heat exchanger control 58, and immediately interrupt the operating means there.
- FIG. 3 is shown as a second inventive embodiment, a further modified system 10, in which already explained components are again provided with the same reference numerals.
- the chimney 50 in this case also forms a main flow path 74 for the hot primary air coming from the afterburner 20.
- the flow path of the hot primary air to and through the heat exchanger 42 follows a bypass flow path 76, which includes the heat exchanger 42 with its inlet line 38 and its outlet line 46 and outside of the main flow path 74 of the hot primary air coming from the post-combustion device 20.
- the bypass flow path 76 thus branches off from the main flow path 74 and flows back into the main flow path 74 downstream of the branch.
- control flow in the event of a fault related to the secondary fluid corresponds to the control flow in the first embodiment FIG. 2 ,
- the arrangement of the heat exchanger 42 in the Bypassströmungsweg 76 has in the specific embodiment, especially flow and thermal advantages, since the flow of exhaust air in the event of a fault, ie when the Bypassströmungsweg 76 is closed, unhindered and largely rectilinearly through the main flow path 74, ie by the fireplace 50, can be done. Thus, cumbersome turbulence and turbulence in the outflowing air can be avoided, resulting in additional safety, for example in the case of failure the sealing or closing function of valves 68 or 70 leads.
- two or more safety valves 68 and 70 can also be arranged in series one behind the other in the inlet line 38 and / or the outlet line 46 of the heat exchanger device 42.
- a secure closing of the corresponding line 38 or 40 is ensured even if one of these several valves 68, 70 should fail and remains open despite missing resources.
- this technique can also be used in systems in which achieved by switching off the Benners 22 no safety-effective cooling of the primary fluid can be. This can be the case, for example, in the case of regenerative afterburner systems, in which hot primary air is still generated by the high heat storage even after switching off the burner, if the process air supply is not terminated.
