Definitions

  • the invention relates to an injection device for wet cleaning of compressors during operation, by means of which the liquid cleaning agent can be introduced into the flow channel upstream of the compressor via a line.
  • An injection device of the type mentioned is known from FR-A-2418355. It concerns the wet cleaning of compressor stages, individually and in cascades. The last compressor stage is cleaned by supplying a liquid, after cleaning this the next higher stage is cleaned, etc. Between the stages the cleaning liquid is dewatered. Due to the pollution of the waste water, the cleanliness of the corresponding compressor stage is estimated. The way in which the cleaning liquid is introduced into the flow channel is not further explained in FR-A-2418355. This known cleaning technology cannot be used in modern (gas turbine) compressors due to their pressure-temperature characteristics.
  • Another injection device known from FR-A-2258102 describes the dry cleaning of the fan blades in the cement industry. No liquid is used for cleaning here, only fine particles are entrained by an air flow.
  • the invention seeks to remedy this. It is the object of the invention to create a device of the type mentioned at the outset, which on the one hand is adjustable in spraying power and spraying direction and on the other hand protects the compressor blading to a maximum degree from forcibly separated parts of the device.
  • liquid cleaning agent is injected by means of an atomizing nozzle which is mounted in a three-dimensionally adjustable manner in a ball joint in the housing wall of the compressor.
  • the advantage of the invention can be seen in particular in the fact that, due to the commercially available nozzle used, performance corrections and settings of the nozzle jet direction and the jet type can be carried out in a universal application with the compressor running without impairing the machine operation.
  • the agent to be injected is usually a mixture of a commercially available concentrate and treated water.
  • this mixture is injected into the flow-through channel 1 via a molecular atomizer 2.
  • This atomizer 2 is fastened in the interior of a ball joint 3 by means of a screw thread in such a way that the nozzle mouth is at least approximately flush with the ball surface.
  • the spray cone has an angle of approximately 90 °. This means that the longitudinal axis of the atomizer against the flow-limiting wall 4 of the compressor housing only has to be set at 45 ° to include the wall zones.
  • the ball joint 3 lies in a joint shell which is incorporated in a housing 5.
  • This housing of preferably cylindrical shape, which penetrates the compressor wall 2, lies with a flange-like bottom on the inside of the compressor wall.
  • the joint shell mentioned is arranged in this base.
  • the cylindrical part of the housing 5 protruding on the outside of the compressor wall is provided with both an internal thread and an external thread. Via the latter, the housing is firmly screwed to the wall 2 by means of a shaft nut 6 and locking plate 7. Via the internal thread, the ball joint 3 is pressed into the joint shell by means of a clamping nut 8 and held in the respective position.
  • the molecular atomizer 2 is connected to a feed tube 9, which at its other end carries a screw connection 10 for receiving a flexible hose connection 11 (FIG. 1), for example.
  • the diameter of the feed tube and the axial length of the cylindrical part of the housing 4 are coordinated with one another in such a way that the feed tube 9 can easily perform a swiveling movement over 90 °, both in the plane of the drawing and perpendicular to it. This means there are no limits to the adjustability of the spray angle.
  • the new facility is extremely easy to maintain. This means that all service work such as cleaning, correcting, checking and repairing can be carried out while the machine is running. Of course, this also applies to the actual replacement of the molecular atomizer in the event of a necessary change in its output or the shape of the nozzle jet. It has been shown that it takes around 15 minutes to replace a nozzle unit.
