Definitions

  • the invention relates to a device for gassing liquids with at least one linear gasser according to the preamble of patent claim 1.
  • gases which also include gas mixtures
  • gases can be introduced into a liquid in two different ways.
  • a distinction is made between gassing into the liquid above or on the liquid surface by diffusion and gassing into the liquid below the liquid surface by pressure, whereby different operational concepts are implemented in each case, such as continuous or intermittent introduction or introduction of the gas with and without circulation of the liquid.
  • Feed systems for gassing below the liquid surface include, for example, rubber membrane or silicone membrane aerators or ceramic aerators in disc, tube or plate design. These aerators are installed on rigid piping systems or combined with hose systems, which are typically attached to the bottom of a tank or reactor as such or in conjunction with an aerator.
  • a disadvantage of known compressed air ventilation systems is the high cost of assembly with fixed and rigid connecting elements or the welding of plastic ventilation lines and the resulting high cost of disassembly in the event of repairs, cleaning or replacement. Problems with contamination and clogging are partly solved by manufacturers recommending in their operating instructions that the systems be subjected to the maximum amount of air and/or gas for a certain period of time each day in order to eliminate the impairments caused by the aforementioned contamination and clogging.
  • organic acids are added to the ventilation systems sporadically or at fixed intervals in order to dissolve organic particles that adhere to the openings and/or to the surfaces of the ventilation.
  • a sewage treatment plant ventilation device for biological or fully biological sewage treatment plants is disclosed, in which ventilation lines are connected to distribution lines.
  • a screw, press, snap or welded connection is generally disclosed for the connection.
  • the publication EN 101 50 180 A1 discloses a water aeration device with horizontally arranged pipes for supplying air and rubber bodies located thereon. A connection of a distributor pipe with aeration elements by means of a bushing and a bolt is disclosed.
  • the publication DE 42 21 357 A1 discloses a device for gassing liquids according to the preamble of claims 1 and 14, in which a ring consisting of pipes or molded parts is connected to cross pipes.
  • the ring comprises T-pieces for a plug connection to the cross pipes.
  • the invention is based on the object of providing a new concept of a leak-proof gassing device that allows easy handling.

  • the other end of the connecting piece is provided with a thread and screwed to the further component.
  • an intermediate piece, the connecting piece is provided, in whose one end of the linear gasifier is inserted via a rubber seal and the other end has a thread, whereby the connecting piece with the threaded end can be screwed to another component.
  • the solution according to the invention is characterized according to claim 14 in a second variant of the invention in that the connection between the linear gasifier and the further component is made via a plug connection which comprises a seal, wherein the plug connection is realized in that the seal is pressed into a connection bore of the further component and one end of the linear gasifier is inserted into the seal, wherein the linear gasifier is held in the seal in a force-fitting manner, wherein the seal has an elastic wall and a central opening into which the end of the linear gasifier is inserted, wherein the elastic wall and the central opening are designed in such a way that the end of the linear gasifier inserted into the central opening is held in the seal in a force-fitting manner.

  • a further advantage is that maintenance of the gassing device is made easier, since components can be easily cleaned, repaired or replaced instead of the entire ventilation system or parts of it, in each case with no or minimal interruption to operation.
  • the solution according to the invention enables all known boundary conditions such as natural irregular or artificial uniform geometry of each individual Water body or an adaptation to installation locations with several geodetic plateaus within a compressed air supply system and simultaneous demand-based control of the gas requirement required at any given time in the respective zones and locations of the respective water body ensures reliable gassing.
  • the linear gasifier is characterized by dimensional stability in the radial direction and elasticity in the axial direction. Due to the radial dimensional stability, it can be part of the plug connection without a special device or special tool and can be inserted into a seal, for example.
