Definitions

  • the invention relates to a ventilation device for ventilation an open space workplace in a workshop, in harmful gas, steam or dust emissions occur.
  • the task therefore arises of supplying a defined Open space painting area within a workshop with tempered supply air and effective, targeted pollutant removal secure from the open space workplace, through which the other areas of the workshop without separation must be kept free of pollutants by means of cabin walls.
  • Round and elongated air inlet elements are intended under the suction duct be understood as they are known from air conditioning technology are.
  • the forced air flow generated by the long throw nozzle exists from a support jet and a surrounding jet, for example rotationally paraboloidal air jacket flow. Which during of the work process developing or separating pollutants are detected by the air jacket flow and over a known suction device discharged. This is how each one is created selected workplace protective "air curtain", which always guarantees clean breathing air to the worker.
  • All workpieces can be moved to a location that is accessible to the crane can be processed within the hall. When painting priming and topcoating and also evaporating or drying in the same place without a Relocation of the workpieces is required.
  • This ventilation system is particularly suitable for large and bulky constructions, that are not placed in a paint booth can.
  • two long-throw nozzles are formed a ventilation section arranged side by side are that the air jacket flows overlap, and the suction channel each below the overlapping area of the air jacket flows a ventilation section is arranged.
  • Polluted particles contaminated air especially in the air jacket flow can be suctioned off in a targeted manner.
  • the strong support jet is created by the off-center suction hardly affected, causing turbulence from stressed can be reduced with pure indoor air.
  • the effectiveness of ventilation for example with a painting booth is comparable.
  • forced air flows are only established where they are is worked. So it is not necessary the whole Work piece with an air curtain to "envelop" the air quality secure at work and pollutant emissions in adjacent areas in the workshop.
  • the air supply channel at least an air heater is connected upstream, which is the sucked in Air warmed above the air temperature in the workshop, see above that tempering at the same time as ventilation and pollutant removal the room air is to be caused.
  • the air speed in the work area is at work, in those with the strong accumulation of suspended particles and / or Aerosols can be expected, advantageously at 0.30 to 0.45 m / s and thus twice as high as with conventional ventilation devices. This creates a high degree of air exchange and achieves a high cleaning effect.
  • the flow rate can be increased up to 2 m / s. This will Heat transfer significantly improved and the drying time reduced. It should therefore be borne in mind that usually such a rapid drying process is otherwise only possible in narrow, closed Cabins is possible.
  • blow-out or suction power is here as that per unit of time flowing air volume defined.
  • the ventilation device Invention creates a directed cross flow on the hall floor, those under elevated workpieces or parked Vehicles pulls in and pollutants from their underside away. At the same time, however, it shields the workplace Maintain air curtain so that also prevents will that pollutant from the workplace in the adjacent area arrive in the workshop.
  • the ratio of the first Suction power to the second suction power corresponds to the second blow-out rate. So will be on the first Long throw nozzle with 60% of the available air volume per unit of time blown out, so with this advantageous training of the method on the arranged below the first long throw nozzle Suction channel with 40% of the power sucked in and vice versa.
  • the sucked in fresh air can after step a) up to A specific temperature setpoint is reached by 2 ° to 5 ° warmed to the air temperature given in the workshop become. This is a progressive warming of the room air reached in the workshop.
  • the specified temperature increase is chosen so low that it is when blowing out the warmed air by means of the long-throw nozzles does not cause disturbances the air flow comes from convection.
  • the ventilation device 100 shows a ventilation device 100 according to the invention shown, which is installed in a workshop 200.
  • the ventilation device 100 consists essentially of a Row of long throw nozzles 110.1, ..., 110.6, on the hall ceiling 230 are arranged, and from suction channels 120.1, ..., 120.3, which are integrated in the hall floor 220.
  • the long throw nozzles 110.1, ..., 110.6 are above a gantry crane 210 arranged, which can be moved on a crane track 212 and are through a common air supply duct 112 fed.
  • a motorized, remotely controllable flap is arranged, with which the flow of each long throw nozzle passes through individually a control unit, not shown, can be regulated, to bring the air to the pollutant source and dissipate.
  • the suction channels 120.1, ..., 120.3 are covered with gratings and are arranged below the hall floor 220 Intake duct 122 connected to each other. At every Suction channel 120.1, ..., 120.3 is a motor-operated, remote controllable flap arranged.
  • Fresh air is supplied by a radial fan 130 via a Pre-filter sucked in.
  • the degree of contamination of the pre-filter is, for example, via signal displays on the control unit displayed.
  • the fresh air is in a downstream Air heater 114, which with hot water or directly with gas or Oil is heated to a temperature difference of approx. 2 ... 5 K. warmed above the hall temperature.
  • the regulation of the supply air temperature takes place automatically via the control unit.
  • a fuse for the air heater 114 is a minimal and a maximum thermostat built in, making overheating impossible is.
  • a first ventilation section 112.1 Form two adjacent long throw nozzles 110.1 and 110.2 a first ventilation section 112.1, in which contaminated Air blown down and through an exhaust duct 120.1 is suctioned off.
  • the exhaust air duct 122 is the exhaust air loaded with pollutants from the workshop 200 removed. The exhaust air is washed out in a known manner and / or filtered dry and then either fed back to the circuit via an air shaft 132 or blown out through a chimney 134.
  • each of the long throw nozzles shown in Figure 1 110.1, ..., 110.6 are distributed over the length of the hall Long throw nozzles arranged. So that in every ventilation section 112.1, ..., 112.3, which are indicated by the dashed lines 5.2 and 5.3 are indicated, an air curtain is generated. Within of each ventilation section 112.1, ..., 112.3 is a Open space job created. A larger one is preferred Open space workstation 240A between the ventilation sections 112.1 and 112.2 or an open space workplace 240B created between ventilation sections 112.2 and 112.3.
  • the suction channels 120.1, ..., 120.3 are arranged so that air is out the air jacket flow 4.1 of the forced air flows 4.1, 4.2 one Ventilation section 112.1 is suctioned off during the support jet 6.1, 6.2 next to the suction duct 120.1 on the hall floor 220 hits.
  • FIG. 2 the inventive method for ventilation of an open space workplace 340 in one Workshop 300 explained with a ventilation device.
  • an inventive one Ventilation device installed in a workshop 300, in which a vehicle 350 on all sides, also from the bottom, can be painted.
  • Fresh air is drawn in, possibly in a not shown Air heater warmed up and into an air supply duct 112, the ceiling 330 of the workshop 300 is appropriate.
  • the fresh air is supplied with a first blowout blown out through a first long throw nozzle 110.1, whereby a first forced air flow 4.1 is caused which the hall floor 320 is directed.
  • a second forced air flow 4.2 with a second blowout, which is smaller than the first blow-out line, blown out by a long throw nozzle 110.2.
  • the regulation takes place by means of Adjustable flaps on the long throw nozzles 110.1, 110.2 and / or are attached in the air supply duct 112.
  • a division of the air flow can also be in a ratio of the blowing rate for air flows 4.1, 4.2 from 60% to 40% to 90% up to 10%.
  • the suction channels 120.1, 120.2 and the working pit 324 are connected to a common exhaust duct 122.
  • About the Extraction ducts 120.1, 120.2 become the exhaust air on hall floor 320 sucked out of the air jacket 5.1, 5.2. This is below the first forced air flow 4.1 with a first suction power on the suction channel 120.1 and below the second Forced air flow 4.2 with a second suction at the Suction channel 120.2 extracted.
  • the suction power on the suction channels 120.1 and 120.2 set so that the blow out under 80% power Long throw nozzle 110.1 arranged suction channel 120.1 is only operated on 20% of the possible suction power and vice versa.
  • the smaller portion of the air flow 4.1, 4.2 when blowing out and suction serves to maintain a sideways next to the vehicle 350 flowing air curtain.
  • the ventilation device is also in accordance with the drying mode the method of the invention used in cross-current operation, to e.g. for a painted commercial vehicle 350 the lower one Area with warm air and an improved and / or to effect accelerated drying.
