Definitions

  • the present invention relates to an apparatus for cleaning air and other gases, in which a liquid bath for washing the dusty air is arranged to the path of the dusty air through the purifier.
  • Air purifiers which use a liquid bath forwashing the air are in themselves known. They work as follows:
  • the dust-containing. air impinging with relatively great velocity on the liquid, on its path through the purifier, sets this liquid into wave motion. By its impact on the liquid surface, the air loses a part of the dust carried therewith, and
  • Figure 6 is a partial longitudinal section through a further form of the apparatus according to the invention
  • Figure 7 is a perspectiveview of further guiding vanes.
  • the air to be purified is fed to the casing I through the conduit 2, which according to Fig ure '1, extends centrally into t'hecasing I from below.
  • the arrangement isso chosen that this introductionpipe 2 for the dusty air, extends centrally from above downwards into the casing l.
  • a stationary leading or guiding member formed of sheet metal, and consisting of vanesfwhich wholly or partially dips into the liquid or arranged immediately above the same, is inserted in the'air path.
  • the guiding vanes are curved and so inserted in the leading or guiding member, that within this member, the flowing air receives a turning movement.
  • Figure 1 shows a longitudinal section through the apparatus according to the invention with passage of the air to be purified in an upward direction.
  • Figure 2 shows a plan of the guide member
  • the guide member 3 consistsin all forms of construction-of a plurality of guiding vanes or scoops which have the object of distributing the air as uniformly as possible over the whole circumference of 360 of the guide member outlet.
  • the liquid 5 serving to wash the dusty air. It is preferably at such'a level in the casing that the guide member as shown in' Figures 1 and 4 dips partially into the liquid. However the arrangement can be so chosen that the liquid completely covers the guide member, orthe liquid level can be immediately under the guide member (see Figure 6) without the mode of working of the apparatus being substantially affected.
  • This mixing can be obtained to a still greater extent by so forming and inserting the blades or scoops 4 that the air on flowing through the guide member is given a strong rotary motion, as
  • the apparatus according to the invention can be used with special advantage where it is a question of freeing very impure air from suspended particles, for example; for the cleaning of air drawn from grinding machines, the cleaning ing, upper and lower guide members in said housing arranged to impart a substantially horizontal direction of flow to the entire air to be purified, said guide members being substantially parallel to each other and the lower of said members beingin the form of a closed bottom, and a plurality of vanes arranged between said guide members to impart a rotating direction of flow tothe air passing between said guide members, .said vanes being essentially greater in diameter than the distance of said guide members from each other and the walls of saidhousing being curved and enlarged at least in the region of and above said guide members and above said liquid bath, said vanes extending almost to said curved and enlarged walls.
  • a'filter insert 8 in which it undergoes a subsequent purification
  • filter medium for the insert can be used-one of the known suitable materials forrthis purpose, such as perforated plates, fabrics, ring bodies etc.
  • the examples according to Figures 1 and 4 show an insert 8 having the form of a conical fr'ustum. It can of course, 'be formed in any other way, e. g, as a cylinder, or as illustrated in Figure 6, a disc.
  • a damping grating 9 Between the filter insert 8 and the wall 6 of the casing I is further arranged a damping grating 9,
  • Apparatus for purifying air and other gases comprising ahousing with curved ⁇ val1s,"aliquid bath in, said housing, upper and lower guide members arranged to impart a substantially hori- ,zontal'direction of fiow to the airgto be purified, said guide members being substantially parallel to each other and to the surface of said liquid bath, and the lower of said members being in the form of a closed bottom, a plurality of vanes arranged between said guide members to impart a rotating direction of flow to the air passing betweensaid'guide members, said curved housing wallsextending almost to said vanes, and a damping grating in the form of a truncated cone and exte'ndih'gf'rom the outlet of Said vanes along the upper portioh'of the housing walls.
