Definitions

  • the present invention relates to a device for binding or precipitation dust according to claim 1.
  • the devices previously used for dust deposition such as Jet pipes with different types of nozzles for generating a water jet, for example are known from the field of fire services, as well as devices from the Irrigation technology usually does not allow reliable rainfall or Binding of, for example, large quantities of building demolition Dust. Some of the known devices have an insufficient range, so that they do not allow dust to be deposited efficiently. Other known devices on the other hand, where a pure water jet is used, the resulting can Do not adequately bind dust particles. Another disadvantage with these Devices are also the high water consumption, high costs and consequential damage due to contamination of the environment and especially the sewers has the consequence. Especially when demolishing or dismantling contaminated parts of the building there is an increased carry-over due to the large amount of water.
  • the object of the present invention is thus to provide a device which is in effectively depositing or binding dust even in large quantities enables.
  • a device for the precipitation or binding of dust solved with a tubular housing with an air inlet side and a jet outlet side, a device for generating arranged in the tubular housing an air jet, at least one between the device for generating an air jet and the jet outlet side arranged in the tubular housing for Introducing a liquid into the generated air jet to create a jet of an air-liquid mixture generate, with the volume flow through the at least one Nozzle introduced into the generated air jet is adjustable.
  • the device according to the present invention thus generates a beam from one Air-liquid mixture in which the liquid in finely divided form from the air jet is transported and thus effectively the dust particles even large dust clouds bind and knock down.
  • the construction according to the present invention enables it, a jet of an air-liquid mixture with a long range generate so that the device according to the invention when used on construction sites and the like can be used effectively and reliably without constant change of location can.
  • the adjustability of the volume flow through one or more nozzles in the generated air jet liquid still allows an optimal adjustment to the respective requirements, such as the amount of that to be deposited Dust, so that water consumption can be minimized.
  • nozzles are provided in the tubular housing, wherein is the volume flow of the air jet that is introduced from each nozzle Liquid is individually adjustable.
  • the individual adjustability of the liquid volume flow of the individual nozzles independently of one another ensures an increased Flexibility and adaptability to the respective purpose and location of the device according to the invention.
  • one or more nozzles with one Pressure be applied the pressure to change the volume flow of the Liquid is adjustable.
  • the pressurization of the liquid ensures on the one hand a finer distribution of the liquid in the air jet, on the other hand can this causes an increased amount of liquid to be added to the air jet is particularly advantageous when it comes to the precipitation of very large amounts of dust.
  • the Adjustability of the pressure of the liquid in the respective nozzle ensures one optimal adjustment of the amount of liquid introduced into the generated air jet the respective requirements.
  • nozzles there are at least one nozzle on a longitudinal axis of the tubular housing and a plurality of nozzles are arranged on an inner wall of the tubular housing.
  • the drive power is also advantageous the device for generating the air jet changeable or adjustable to the To change the volume flow of the generated air jet. Through this measure, the Range of the jet from the air-liquid mixture arbitrarily between approx.
  • the device according to the invention is pivotally arranged on a carrying device.
  • the device according to the invention can be pivoted horizontally and / or vertically to orient the generated jet from the air-liquid mixture as desired can.
  • the carrying device can, for example, on a vehicle trailer or The like can be arranged to the device according to the invention quickly and easily to be able to move from one place to the next.
  • Figure 1 shows a cross section through an inventive device for binding or Precipitation of dust, which is arranged on a vehicle trailer.
  • the binding device 1 comprises or precipitation of dust a tubular housing 2, for example a can have a round cross-section.
  • the tubular housing 2 has an air inlet side 4 and a beam exit side 5.
  • air inlet side 4 air from an axial fan 7 sucked in and bundled into an air jet.
  • beam exit side 5 occurs the air jet enriched with a liquid, in the example shown with water the housing 2 out.
  • a grid 3 is arranged on the air inlet side 4 of the housing 2, the blades 8 extending radially from the axial fan 7 from damage protected by objects entrained with the air jet.
  • the axial fan 7 is in the housing by means of fastening devices, not shown 2 attached, the power supply of the axial fan 7 from the outside through the Fasteners runs.
  • the blades 8 of the axial fan 7 rotate in operation about a longitudinal axis L of the housing 2.
  • One of the beam exit side 5 facing front part 6 of the housing 2 has such inclined walls that the Diameter of the housing 2 reduced towards the beam exit side 5. Of the Front part 6 can be opened for service purposes.
  • a Nozzle 1 On one of the front of the axial fan 7 facing the beam exit side 5 is a Nozzle 1 arranged, which is located in the center of the housing 2 on the longitudinal axis L. Through this nozzle 10, water is fed into the axial fan 7 via a feed 12 generated air jet introduced.
  • On the inner wall of the front part 6 of the housing part 2 are further nozzles 11 mounted in the circumferential direction and spaced apart from one another which is also introduced into the air jet generated by the axial fan 7.
  • the liquid for the nozzles 11 is the housing 2 and the front part 6 of the Housing 2 supplied to the nozzles 11.
  • the feed 12 for the nozzle 10 also opens into the housing 2. The water is thus supplied to the nozzles 10 and 11 partially in or on the housing 2.
  • the housing 2 can be insulated on the inside, with an additional heater on the inside of the housing 2 can be provided to freeze the supplied water accordingly to avoid low temperatures.
  • the device for binding or depositing dust is as shown in FIG. 1 is attached to a vehicle trailer 16 by means of a support 15.

  • the high pressure pump 14 is adjustable so that the pressure at which the water is applied, can be changed as desired. In the example shown, this is the pressure for all nozzles 10 and 11 is set simultaneously. However, it is also possible independent pressure controls for each individual nozzle or for some of the nozzles to provide. Corresponding devices can also be provided, which an individual adjustment of the volume flow of the respective nozzle 10, 11 in individually regulate the generated air jet.
