Definitions
- the invention relates to a device and a method for the treatment of webs, in particular of textile webs, with at least one IR emitter, the IR radiator with a combustion air fan and fuel gas supply means and controllable in its heating capacity via a control device is.
- Such devices are particularly used for drying webs.
- the amount of fuel gas is known from practice controlled by a temperature controller. Dependent on the amount of fuel gas is then the required Combustion air through another control loop customized. The quantity is usually metered by throttle valves controlled by motors become. For the ignition of the IR emitter is also a separate facility is necessary.
- the invention is based on the object, the device according to claim 1 or the method according to claim 7 simplify and operational security too increase.
- the inventive device for treating webs has at least one IR radiator, wherein the IR radiator with a combustion air fan and fuel gas supply means in connection and via a control device in its heating capacity controllable is.
- the combustion air fan is in his Speed adjustable and stands with the control device in such a way that the speed to a desired Heating power can be adjusted.
- the Fuel gas supply means a pressure regulator, which the Amount of fuel gas depending on the combustion air fan generated air pressure regulates.
- the Fuel gas supply means a pressure regulator, which the Amount of fuel gas depending on the combustion air fan generated air pressure regulates.
- the Fuel gas supply can thus be completely motor-driven Throttle valves for metering the combustion air or the fuel gas can be dispensed with.
- IR emitters for example Ceramic emitters used, they glow due to their relatively large mass relative long after, causing damage to the web can. To protect the web in such cases, has therefore developed constructions in which the IR radiators can be swung away.
- Another known solution provides that between the web and IR illuminator is pulled up a protective curtain. such
- protective measures are relatively complex.
- the cooling time of the IR radiator compared to ceramic emitters considerably shorten because the ceramic spotlights due to their high Need a slightly longer cooling time.
- the combustion air fan is expedient via a frequency converter from the control device controlled to change the speed.
- the control device can with a temperature and / or humidity sensor related to the heat output of the IR radiator by changing the speed of the Combustion air fan to a desired value adapt.
- the frequency converter is used to ignite the IR radiator a certain speed of the combustion air fan driven. This can always be done with a exactly defined heating output can be started. A separate ignition bypass circuit is therefore not necessary.
- the control device in connection with the temperature and / or humidity sensor released so that the temperature or Moisture automatically to the preselected setpoint can be driven.
- the frequency converter limits the minimum and maximum fan speed. Thereby the minimum and maximum heating output of the IR radiator limited. Within this speed range continuous power control is guaranteed.
- the device shown in Figure 1 in a block diagram for the treatment of webs in particular points one or more IR radiators 1, a combustion air fan 2, fuel gas supply means 3 and a control device 4.
- the IR emitter 1 stands with the combustion air fan 2 and the fuel gas supply means 3 in conjunction with the control device 4 the speed of the combustion air fan 2 can be changed so that the speed to a desired Heating power can be adjusted.
- the IR radiators 1 are on one or both sides of a web 5, in particular one textile web, arranged.
- the web 5 is relative to the IR emitters 1 transported.
- the IR emitters 1 transported.
- the IR emitters 1 are two IR emitters above the web 5 shown.
- dashed lines are two further spotlights indicated on the underside. The number the arranged in and across the transport direction IR emitter depends on the respective requirements.
- a temperature and / or moisture sensor 6 In the area of the web or somewhere in the area of Exhaust air path of the device is a temperature and / or moisture sensor 6 is provided, its output signal the control device 4 is supplied.
- the Control device 4 controls a frequency converter 7 the speed of the combustion air fan 2 in order depending on the signal of the temperature and / or Moisture sensor 6 the heating power of the IR radiator 1 to adapt to a desired heating output.
- the fuel gas supply means 3 have in particular one Pressure regulator 30, which depends on the amount of fuel gas of the combustion air fan 2 generated Combustion air pressure regulates.
- the pressure regulator 30 stands thus via a sensing line 31 with the combustion air line 20 in connection.
- the pressure regulator 30 doses thus automatically the pressure of the fuel gas in the Fuel gas line 32.
- the desired ratio of combustion air pressure to fuel gas pressure can be on the pressure regulator set manually or electrically.
- the fuel gas supply means naturally have more known devices, such as solenoid valves 33, pressure indicators 34, pressure switch 35, another Pressure regulator 36 and a gas flow meter 37 on.
- a mixer 8 is provided in which the combustion air mixed with the fuel gas to form a gas-air mixture becomes.
- the mixer 8 can in particular be used as a DC mixer or countercurrent mixer.
- the mixer 8 designed as a counterflow mixer. Is on the input side the mixer 8 via the combustion air line 20 the combustion air fan 2 and via the fuel gas line 32 connected to the fuel gas supply means 3.
- the fuel gas line 32 thus opens into the combustion air line 20 a that the fuel gas 38 in countercurrent introduced to the combustion air 23 and with this is mixed to the gas-air mixture 11.
- the mixture in Counterflow mixer has compared to the DC mixer higher flow losses, however, is essential more intense, so that an evenly mixed gas-air mixture 11 arises. This in turn leads to a better and more even combustion.
- the gas-air mixture 11 is via the gas-air mixture lines 10 fed to the IR radiators 1.
- the IR radiators 1 can be used, for example, as ceramic radiators be trained. Leave particularly advantageous however, use IR radiators in the context of the invention, whose radiator surface consists of a metal mesh.
- a radiator is shown schematically in Fig.2 shown. It essentially consists of a distribution chamber 12 and a metal mesh 13, for example on a support grid, not shown is spanned.
- the metal mesh 13 can for example formed by a sintered metal mesh become.
- the actual firing zone 14 takes place on the outer Surface or inside of the metal mesh 13 instead of.
- the heat transfer can depend on the type of Firing conditions are done by radiation or convection.
- the control device 4 released so that the heating power automatically moved to the specified setpoint becomes. Via the signal from the temperature and / or humidity sensor 6, the control device 4, the heating power by changing the speed to a desired one Maintain level.
