Definitions

  • the invention relates to a combination according to the preamble of claim 1. It thus relates to a combination of a building for waste treatment or waste utilization or from a warehouse for waste collection or waste disposal on the one hand, and a device for shielding openings of the building, in particular of gates or Doors of the building on the other hand.
  • the building may in particular also be a composting plant, waste recycling plant, waste incineration plant or a landfill bunker, which will also be referred to as waste landfills in the following description.
  • the device for shielding openings can be provided in particular at unloading, task orrapbunkem or other facilities for delivery, transport and storage of waste.
  • Object of the present invention is therefore to provide a structurally simple, inexpensive to manufacture and easy to handle device on a building of the type mentioned above, which provides a permanently safe and effective shielding of the environment against internal and polluting air conditions such as dust and odor and at the same time allows a simple and fast to prepare and be carried out dumping process in the landfill or plant, without undermining the required by the German Federal Immission Control Act conditions.
  • the device according to the invention provides a cost-effective shielding for waste treatment plants or landfills, which shields especially in the room separation opening contours, for example, the contour of an unloading vehicle safely and effectively against internal and polluting air conditions such as dust and odor.
  • a complex and time-consuming opening and closing of multiple lock gates during Abkippvor réellen is no longer necessary.
  • the device according to the invention is inexpensive to manufacture with a simple construction and easy to assemble and handle.
  • the fact that the previously required for shielding Vorschleuse can be omitted, leading to the operator of a landfill to significant cost savings in the purchase and operation.
  • the air not only the landfill opening per se, but also the contour of a vehicle located in the opening and also the spaces below a tipper or below the vehicle axles can be detected and securely sealed off.
  • the device of the invention uses the so-called “Coanda effect", so that the obliquely incident on the vehicle contour Nestle air jets at a certain angle on the vehicle and flow along the contour of the vehicle into the building.
  • the previously calculated air volume of this jet prevents on the one hand the escape of dust- and odor-laden air and thins on the other hand, because it is outside air, the odorous air inside the landfill, which in turn benefits the installed exhaust air purification.
  • the core air jets emerging from the core air jet nozzles are directed through the opening into the landfill at an angle of 15 ° -45 °. This allows a particularly safe and effective shielding can be achieved.
  • two core air jet nozzles are arranged on opposite sides of the opening.
  • the lateral core air jets are each formed by an extremely high narrow flat jet.
  • two core air jet nozzles can be arranged on mutually adjacent sides of the opening.

  • the core air jet nozzles are arranged in several planes in front of the opening.
  • the core air jet nozzles or the individually controllable sections of a core air jet nozzle extend uniformly or non-uniformly over the entire height or width of the opening. In this way, an optimal shielding of the landfill opening can be achieved and leakage of odor-laden or dust-laden air of the landfill bunker to the ambient air can be reliably prevented.
  • the core air jet nozzles are connected to the front side or laterally or longitudinally with the air blower.
  • a plurality of core air jet nozzles can be connected via connecting lines to a common air blower or each core air jet nozzle can be connected to a separate air blower, wherein the core air jet nozzles can then be operated with the same or with different volume flows.
