Definitions

  • the invention relates to the preamble of claim 1, on an arrangement for cleaning the exhaust air from spray paint booths and finds in particular Use on so-called Venturi washout systems.
  • the washing liquid which absorbs the overspray and all other impurities e.g. production residues, such as film residues, plastic parts and the like, as well as other dirt particles, is fed to a collecting tank via one or more collecting troughs, partly disposed of and fed back into the feed system of the washing system.
  • Another problem with known systems is that particularly in the water distribution channels that for a constant and even sprinkling of the wall and / or floor surfaces of the spray booths, with the time stops the solid particles from being deposited, which is then still in a complex manner by Need to be eliminated from time to time.
  • FIG. 1 shows a spray paint booth in cross section with an underlying arrangement for Cleaning the exhaust air according to the invention.
  • a grate 2 of a cabin 1 are predominantly over the over the entire base area trickle sheets 3 and 4 arranged. These 3 and 4 are inclined on one side and Partially overlap, creating an air duct 14 arises.
  • the lower trickle plate 4 is at his to the washout nozzle 11 pointing, higher lying edge with a weir 6.
  • the elements 3, 4 and 6 are also arranged so that the air duct 14 essentially is off-center.
  • a collecting channel 8 which is preferably part of the pouring plate 4.
  • a so-called Venturi wash-out system is arranged downstream of these flow plates 3 and 4 and below these 3 and 4.
  • the washout nozzle 11 is arranged with a vertically oriented flow direction, and it itself 11 and the system of baffle plates following this 11 are eccentric, based on the cross-section of the spray paint booth, for acoustic reasons and are arranged under at least one pouring plate.
  • a further feed system 9 for washing liquid is assigned to the guide plates 10 upstream of the washout nozzle 11.
  • the exhaust air duct 15, which has previously been outside the basic dimensions of the cabin 1, is an integrated component according to the invention and is located under at least one trickle plate.
  • the dirty washing liquid and the Washing liquid containing paint particles thus clearly separated and in downstream systems disposed of or recycled.
  • the main advantages of Arrangement according to the invention are in the reduction the noise level, the reduction in susceptibility to interference of the continuous flow of production, one better condition for an almost complete "Overspray paint” recovery and in economically constructive Savings such as the diminished Space requirements.
  • distributor plates VT also run inclined to the horizontal, extend over the entire length of the channel R and are labyrinthine from both sides RS 1 and RS 2 of the channel R and partially overlap Ü are directed towards one another and are arranged at a height distance A from one another, the distributor or baffle plates VT furthermore variable or adjustable on the channel walls RS 1 in terms of their angle of inclination ⁇ and / or their effective length L and / or overlap Ü and mutual height distance A and RS 2 can be arranged.
  • each a collecting trough 8 is provided, the here too Collecting channel 8 is an integral part of the flow plates 3 'and 5 can be.
  • the outside of each gutter 8 is advantageously a weir 6 'or 6' ' educated. This variant takes place especially at very high dirt application.
  • trickle sheets 3 and 4 are preferred in the longitudinal direction of Appendix A. arranged inclined on one side.
  • a pouring plate 4 ' is provided at the same height as the pouring plate 4, indicated by dashed lines in FIG. 3.
  • the correspondingly narrower pouring plate 4 is located below the pouring plates 3 and 4 '.
  • the collecting channel 8 is preferably for the dirty water liquid on one and that Feed system 7 on the opposite end S of system A, see Fig. 3a.
