Definitions

  • the invention relates to methods for removing contaminated air from rooms according to the preamble of claim 1. It further relates to devices according to the preamble of claim 4 for carrying out the method.
  • suction devices are positioned in the rooms at one or more places. These suction devices consist of a hood to which an exhaust fan is connected. In order to work under it, the hoods would have to be positioned as high as possible. But then the suction effect is reduced. To be effective, these suction hoods are thus positioned as close as possible to the source of the load. However, this considerably limits the freedom of movement in this area.
  • the present invention has for its object to provide a method and a device suitable for carrying out the method, by means of which it is possible in a simple manner to reduce or eliminate the burden of indoor air and at the same time to maintain freedom of movement.
  • the present invention is based on the principle to transport the loaded air with the help of at least one laminar, directed to the suction air jet targeted to the extraction point.
  • Such an air jet sucks the polluted air as it were, being mixed with the air of the air jet.
  • the polluted air is both diluted and cooled or heated as needed.
  • a plurality of bundled air jets are blown from a plurality of mutually spaced nozzles to the suction point. In this way, with only one suction point, an almost arbitrarily large amount of the polluted air per unit time can be eliminated.
  • the device according to the invention is particularly simple. It consists of a suction point positioned in the space of conventional type and at least one nozzle, which blows a bundled, laminar air jet into the room, wherein the air jet is directed to the suction point. Due to the pressure difference between the bundled air jet and its surroundings, the contaminated ambient air is sucked into the air jet and transported to the extraction point. The amount of air sucked in has the positive effect that it increases the amount of air moved accordingly, so that the air jet carries very far. The larger the distance between the nozzle and the extraction point, the greater the amount of ambient air sucked in. The extracted air quantity is therefore much larger than the amount of air injected through the nozzle. The system of the invention thus requires little additional energy.
  • the nozzle has a circular cross-section. It has been found that such nozzles bring the best effect.
  • the nozzle has a conical opening. This also contributes to the optimal effect.
  • nozzle box In the case that a plurality of nozzles are used, they can be combined in a nozzle box according to a preferred embodiment.
  • the nozzle box consists of a tube whose one end is closed by means of end cap and in the other end of a blower fan is used.
  • the nozzle box a heating or a cooling coil can be assigned.
  • the nozzle box and an air filter can be connected upstream, for. B. to prevent contamination with dust and the like.
  • a suction funnel 1 of conventional type, for example, mounted under the ceiling of a room, to which a suction fan (not shown) is connected.
  • a nozzle 2 is positioned below the suction funnel 1. This has a circular cross section and a conical opening. From the nozzle 2 emerges a bundled laminar air jet 3, which is directed to the suction hopper 1. Due to the pressure difference between the air jet 3 and the ambient air parts 4 of the ambient air are sucked and transported together with the bundled air jet 3 to the suction hopper 1. With the sucked in ambient air 4, the existing there pollutants and pollutants such as dusts, fumes, odors, humidities, etc. are sucked.
  • Fig. 2 shows a nozzle box 10 with integrated fan 11.
  • the nozzle box 10 consists of a tube 12, in one end of the fan 11 is seated and the other end is closed with an end cap 13.
  • Special air outlet nozzles 14 are arranged in series and produce a stable one with a relatively small amount of air Air jet belt, which serves for receiving and transporting contaminated room air. With a special tripod (not shown) for holding the nozzle box 10, the air jet can be directed in almost any direction.
  • Fig. 3 shows an application example of the invention.
  • the nozzle box 10 with integrated fan 11 is mounted vertically standing next to a welding table 5, 6, so that the air jets 3 emerging from the nozzles 14 flow past the table surface 6 approximately horizontally.
  • the suction hood 1 On the opposite side of the welding table 5, 6, they meet the suction hood 1, which is also mounted there in a standing position.
  • nozzle box 10 a heating or cooling register to the nozzle air depending on Need to heat up or cool down.
  • an air filter box can be connected upstream in the recirculation mode.
