Definitions

  • the invention relates to a device for the treatment of solid, liquid and / or gaseous substances according to the preamble of claim 1.
  • Such a device is known from GB-A-1 101 981 and is used there for the production of curable compositions, in particular of building materials such as concrete, mortar and the like, where Binder, aggregate and liquid, preferably Water, simultaneously or as a batch in the activator with coaxial arranged opposing rows of blades, the particles of material in the activator from the inside out moved and crossing the rotating rows of outer blades be excited with increasing amplitude. Between two narrow rows of blades is a wide row of blades arranged, which has the consequence that the excitation frequency for a particle migrating outwards from the center fluctuates.
  • the impact blades used here have circular, Triangular or rectangular cross-section and have the disadvantage on them - especially when using highly erosive media - Subject to relatively high wear, because between the Blade surface and the moving particles high relative speeds of more than 200 m / s occur. At At these high speeds, there is no protective layer between the blade surface and the one on the impact blade form hurled particles.
  • Hardenable compositions of the type mentioned usually consist of a binder, from aggregates and from a liquid, in general water. In the case of concrete it is with the binder around cement. Sand is used as an aggregate used, however, partially or completely by Substitutes, such as ground rubble, are replaced can.
  • a disintegrator is known from EP-A-48 012, which can be used for the production of concrete. Through this known Disintegrator can with the same strength Cement portion of the concrete can be reduced.
  • AT-B-395 295 was an activator for mixing, crushing or the like.
  • the work tools run essentially radially from the inner edge to the outer edge of the respective ring washers, the spaces between the washers are sealed.
  • sealing elements for. B. flexible Plates or broom elements, at the radially inner end of the work tools arranged.
  • the size of the disc diameter and their widths, as well as the number of work tools per Disc and speed of rotation must be dependent be coordinated accordingly from the respective application.
  • Coal slurries are slurries of coal dust in Water and / or oil. Such slurries would be very suitable Transport coal in pipelines.
  • the sedimentation effects mentioned above however, prevent permanent provision such mixtures with a sufficiently high carbon content.
  • DE-A-32 20 328 is a disintegrator gas scrubber known, with the gases simultaneously with a washing liquid undergo mechanical treatment.
  • the disintegrator is based on a rotor / stator principle built up, that is, fixed and rotating alternate Row of blades off.
  • the object of the invention is the extent of the activation that can be achieved of the particles and thus the performance of the device as well as increasing the quality of the manufactured products without deteriorate the life of the device.
  • the individual particles are moving at speeds of more than 200 m / s against the blades and mainly hurled against each other and strong impacts exposed. Further investigations have shown that the individual Obtain particles between three and ten collisions. By these impacts occur with solid media in addition to shredding the grains to defects in the crystal lattice and macroscopic Defects that result in an increase in surface area to have. Furthermore, an improved binding of the liquid and solid components of the mixture reached.
  • the impact blades are concave and preferably from at least two substantially flat and there are angled plates.
  • the form is subject to a requirement during operation processing medium on the blades. This edition renewed is constantly protected and protected by the impact of particles the blades themselves largely from erosion and wear.
  • a better radial mass transfer is achieved in that between two adjacent flapping blades of the outermost Blade row a fan blade is arranged. Furthermore, it is advantageous if at the outer end of each beater blade the outermost row of blades on the in the direction of rotation side of the rotor, preferably at a right angle the impact blade connects to a fan blade.
  • Another object of the invention is to provide a method of treatment of several components having solid, liquid or gaseous substances with a device according to the invention to propose.
  • the particles of Fabrics when crossing the outside by at least their width 2%, preferably at least 5% and at most 10% decreasing rows of blades excited with increasing frequency will.
  • This method according to the invention has proven particularly useful in the production of coal dust suspensions, in which as Starting materials water and / or oil and coal dust are used will. Such suspensions are possible with the invention to produce with a high solids content that lasts for a long time Periods are stable.
  • the speed of the rows of blades is between 950 and 2800 rpm. This allows suspensions with special produce a high solids content.
  • This method according to the invention is for various cleaning processes suitable. So a liquid medium, like water or milk of lime, before introducing the gas into the activator be injected into the gas. However, it is also possible to inject such a medium directly into the activator.
  • the invention also encompasses dry processes, such as. the task of finely ground dolomite.
  • the cleaning medium before the injection Solids be one or more of the cleaning medium before the injection Solids added.
  • the cleaning medium before the injection Solids When entering the activator you can these solids in dissolved form or as suspended particles available. Is it about cleaning the Gases around a desulfurization process, as is the case with flue gases is often required, the serving as a carrier medium Lime, dolomite or the like are added. In the activator then in addition to an intimate mixture of all components also an activation and thus an almost complete one Implementation.
  • This process is characterized by its particularly high separation performance out.
  • the suction fan can also be used in power plants omitted.
  • the speed of the Bucket rows is between 900 and 3500 1 / min.
  • Figure 1 an inventive Activator partly in section; the figure 2 a section along line II / II of Fig.1; 3 shows a variant the blade shape and the Fig.4 another embodiment from that.
  • the activator shown in Fig. 1 and 2 consists of two opposing directions moving rotors 1 and 2, whose direction of rotation with the Arrows A and B are indicated. For the sake of simplicity the housing with central inlet and peripheral outlet omitted.
  • Get the processing of the goods to be treated three concentrically arranged rings 3, 4, 5 of impact blades 6.
  • At least that Impact blades 6 of the outer ring 5 are concave, e.g. angled.
  • the base level 7 of this blade is below made an angle ⁇ , as in Fig. 2 he is recognizable from one at the leading edge of the blade Plane 7 extending in the circumferential direction to the tangential plane 7 ' is measured.
  • the two inner rings 3 and 4 are concave Buckets 6 equipped, which consist of two substantially planes Plates 6 'and 6' 'exist.
  • This Edition which is designated with 11, is renewed by the Impact of particles continuously and protects the blades 6 even largely against erosion and wear.
  • the flapping blades are the angled part 6 'or 6' 'shorter than the remaining part 6 '' 'and is preferably the Half or less of the total length of the blades.
  • the angled end pieces 6 ', 6 '' can be on both ends of the part 6 '' 'or only on one End of the same, in the present case preferably on the trailing side Be provided at the end. They are expediently made of hard metal manufactured or occupied and can be replaced to be appropriate. However, it is also made from ceramic or plastic possible. Finally, there is also the possibility the outer edges of the Parts 6 ', 6' 'to be covered with protective strips 10.
  • fan blades 8 can have any shape and for example as Plate, fingers or the like. Are formed. You have the task the flow of the material to be treated from the inside out secure and also on the rotor axis facing Surface of the striking tools a protective layer from the form treating material, no matter how large the angle of attack ⁇ is. This can be used for certain work 15 ° while lying about it for other work, for example 20 to 35 °, may be more advantageous.
  • FIG. 3 shows schematically a section from three successive rings of the activator according to the invention. It is essential that the widths b 1 , b 2 and b 3 of the rings continuously decrease towards the outside by at least 2-5%. However, the maximum width should decrease by 10%. This means: 0.9 b 1 ⁇ b 2nd ⁇ 0.98 b 1 0.9 b 2nd ⁇ b 3rd ⁇ 0.98 b 2nd .
