Definitions

  • the invention relates to a method for cleaning roads according to the preamble of claim 1 and to an apparatus for carrying out this method.
  • the aim of the invention is to propose a method of the type mentioned, in which not only the dust load, but also the particulate matter pollution is reduced as much as possible.
  • the individual water droplets should not be too large, so that a given amount of water as large a number of water droplets can be formed, resulting in a correspondingly large number of collisions with particulate matter.
  • the individual water droplets should not be too small because Otherwise they will be carried away by the air flow due to the low mass.
  • the proposed minimum size has the advantage that the individual water droplets leaving the nozzles at high speed have sufficient mass to not be immediately entrained by the air flow, and therefore a relatively large number of collisions of the water droplets with the particles comes, which leads to a binding of the particles, in particular dust particles, through the water.
  • Another object of the invention is to propose an apparatus for carrying out the method according to the invention.
  • the size of the droplets ensures that, due to their kinetic energy, they can penetrate to a sufficient extent to the middle of the suction line, so that essentially the entire cross section of the suction line is moistened by the nozzles distributed over the circumference.
  • the features of claim 6 may be provided. Even with such nozzles, it is possible to keep the size of the droplets in a narrow band.
  • the nozzles can essentially only be optimized for one operating state. With a change in operating parameters such as air velocity in the suction line, dimensions of the line and the pressure with which the nozzle is operated, a new optimization should be made.
  • FIG. 1 shows schematically a device according to the invention
  • Fig. 2 shows a detail of this device.
  • the device according to the invention e.g. can be installed in a street cleaning vehicle, has a suction line 1, which opens into a collecting container 2.
  • a suction line 1 which opens into a collecting container 2.
  • devices for the deposition of particles are installed (filters, baffles ).
  • the interior of this collecting container 2 is connected to the suction side of a suction fan 3, wherein air laden with particles flows into the collecting container 2 via an inflow opening 4 of the suction line 1.
  • the particles e.g. Road dust, isolated.
  • the air enters the suction fan 3 and flows through an exhaust duct 5 into the open air.
  • the outflow opening 6 of the exhaust air line 5 is arranged near the inlet opening 4 of the suction line 1.
  • nozzles 7 are arranged in the form of a nozzle ring and protrude into the interior of the suction line 1. These nozzles 7 are connected via a pressure line 8 with a pressurized water source 9 (eg pressurized container). The water pressure can also be applied via a pump 10.
  • a pressurized water source 9 eg pressurized container.
  • the water pressure can also be applied via a pump 10.
  • the nozzles 7 are preferably designed as 2-fluid nozzles with internal atomization or as 2-fluid nozzles with beam shaping by laterally arranged compressed air nozzles to produce a flattened spray.
  • the water droplets in the specified size range ensures that the droplets have a sufficiently large kinetic energy to penetrate to the middle of the suction line 1 flowing through the air flow and also to be able to fly a certain distance against the air flow. This leads to numerous collisions of the droplets with the particles contained in the air flow, and these are moistened accordingly.
  • the nozzles 7 have in the best working range for the larger drops an initial speed of about 6 m / s, for the smaller droplets such of about 4 m / s. Most of the speed is lost in the first centimeter flight path, as the air resistance increases with the 3rd power of the speed.
  • droplets After a 500 mm flight path, droplets have a velocity of 0.19 to 1.58 m / s, depending on the size.
  • the droplets emerging from the nozzles 7 counter to the direction of flow of the air stream are decisive for the cleaning effect since they bind most of the dust due to the higher number of collisions with particles contained in the air stream.
  • the airflow with the flying droplets have only a small effect.
  • the nozzles 7 have a device for beam shaping.
  • tongue nozzles are appropriate.
  • another wetting agent may be used or the water may also contain additives such as surfactants or the like.
