  • a filter device preferably being connected between the at least one suction wall opening and the suction device in the collecting line.
  • the smoke vapors that occur in various work processes often contain harmful particle emissions that can be above the respectively permitted limit value. Problems of this kind have occurred particularly in the galvanizing processes in the metalworking industry.
  • the white smoke generated by galvanizing metal objects by evaporating the middle of the river must be detected and fed to a filter system.
  • Modern systems are equipped with an enclosure that encloses the entire zinc bath area. This consists of a self-supporting steel structure, which is usually passed through in the middle.
  • the system fan is started up in order to set the suction quantity required for the process. Then the dipping process is carried out, which results in a very strong smoke gas development.
  • the object of the invention is therefore to provide a system of the type mentioned at the outset, with which emission of flue gases from the passage gap of the dwelling can be avoided.
  • Another object of the invention is to provide a system that enables an existing system to be upgraded with a low installation cost.
  • this is achieved in that at least one suction duct is provided outside the housing, the suction opening of which is at least partially arranged in the region of the outer edge of the passage gap, via which suction duct the smoke gases escaping from the housing through the gap can be extracted.
  • the suction opening of the at least one suction channel is arranged in the region of one of the two longitudinal edges of the passage gap.
  • suction opening cross-section is substantially at right angles to the gap cross-section.
  • the smoke gas detection system according to the invention can also be retrofitted into an existing system with little construction effort, and a high degree of efficiency can be achieved with the additional extraction.
  • An advantageous embodiment of the invention can consist in that the suction opening cross section is approximately the same size as the gap cross section.
  • a design in this form results in flow velocities for the flue gases to be sucked in, which enable a very efficient implementation of the used suction power.
  • suction opening cross section is rectangular.
  • the suction channel is box-shaped and with a side wall parallel to the housing ceiling, and that the suction opening cross section is formed by at least one longitudinal opening and an outlet cross section by at least one opening on the opposite long side of the box-shaped suction channel, which outlet cross section is connected to another suction device.
  • Such a box can easily be retrofitted onto an existing housing in order to completely remove the smoke gases that are produced.
  • outlet cross-section is composed of a plurality of longitudinal openings in the intake duct, each opening being led via a funnel-shaped extension into a branch line, which branch lines open into a further collecting line.

  • the further manifold for the branch lines of the suction channel together with the manifold coming from the housing are guided via a controllable throttle valve into a main line which opens into the suction device.
  • a further embodiment of the invention can consist in that a further suction channel is arranged in the area of the other edge of the passage gap opposite one another.
  • This measure can further increase the efficiency of the additional suction at the passage gap.
  • an air ejection channel is provided outside the housing, and that the ejection opening is arranged opposite the suction opening cross section, the passage gap being located between the ejection opening and the suction opening.

  • a flue gas detection system is shown with a schematic representation of the flue gas flow caused by the suction, the paths traversed by the extracted gas are symbolized by arrows.
  • a discontinuously emitting flue gas source 13, which is fed by the reaction of a galvanizing bath 21 (FIG. 2) when an object is immersed, is surrounded by a double-shelled housing 5, 14, so that an interior space 6 formed by the housing 5, 14 by suction from the Flue gas emissions from the flue gas source 13 can be exempted.
  • an elongated passage gap 25 is provided in the ceiling 14 of the housing 5, 14, through which a supporting cable 20
  • a crane system 18 (FIG. 2) runs through which the part to be galvanized is moved into the housing and this is immersed in the bath.
  • a suction device (not shown) is provided, which is connected to the interior 6 of the housing 5, 14 via a suction wall opening 7, a branch line 4 and a main line 22. Between the suction wall opening 7 and the suction device there is also connected a filter device, not shown, which separates the dust and the smoke particles. In the interior 6 of the housing 5, 14, a negative pressure thus arises which prevents the flue gas from flowing out laterally during operation.
  • the invention now consists in that a suction channel 1 is provided outside the housing 5, 14, the suction opening 16 of which is at least partially arranged in the region of the outer edge of the passage gap 25.

  • FIG. 1 A further possibility of the still improved extraction of smoke gases passing through the passage gap 25 can be seen in FIG. 1.
  • An air ejection channel 2 is provided outside the housing 5, 14, the ejection opening 27 of which is arranged exactly opposite the suction opening cross section 26, the passage gap 25 being located between the ejection opening 27 and the suction opening 26.
  • air is blown in the direction of the suction cross section 26, as a result of which even more smoke gas particles can be entrained into the suction channel 1.
  • the suction opening cross section 26 is approximately the same size as the gap cross section 25 and the suction opening cross section 26 is rectangular. In this way, there is a uniform suction of the flue gas along the elongated gap 25.
  • the suction channel 1 is box-shaped and formed with a side wall parallel to the housing ceiling 14, the suction opening cross section 26 being realized by a longitudinal opening and an outlet cross section 29 by an opening on the opposite long side of the box-shaped suction channel 1. Furthermore, the outlet cross section 29 is connected via a short line 8, which widens to a funnel 10, to a further suction device, which is not shown in FIG. 1. As in the exemplary embodiment according to FIG. 2, this further suction device can also be created by allowing another collecting line 31 to open into the main line 22 of the suction device for the interior of the housing 5, 14.
  • the main part of the suction is distributed over several wall openings 7 in order to enable the most favorable detection of all smoke gas components of the interior 6 along the gap 25.
  • This further manifold 31 is brought together with the manifold 30 coming from the housing 5, 14 by means of a controllable throttle valve in the main line 22, which conducts the collected flue gases to the filter and suction device, not shown.
  • the inner throttle valve can now be adjusted as required so that a distribution of the suction flows which is favorable for the galvanizing process is achieved.
  • wooden strips 40, 41 are arranged above the suction duct 1 or the air ejection duct 2 and the passage gap 25, partially overlapping on both sides in the longitudinal direction thereof, which further reduce the passage gap 25 and make it more difficult for smoke gases to escape.
  • the wooden strips 40, 41 have the advantage that their wear, which occurs over time due to the back and forth of the suspension cable , only wooden parts or wood chips can fall into the galvanizing bath 21, which do no further damage to it, while rubber components can get into the bath 21 when they are detached from the housing ceiling and can impair its effectiveness.
