Definitions

  • the invention relates to a multi-chamber Hydrocyclone separator with a large number of individual Hydrocyclones for the separation of solids or Liquids from liquids, especially for separation of oil from an oil-water-sand mixture like it in oil production in the off-shore area, whereby the hydrocyclone separator is an inlet opening for the Oil-water-sand mixture, an outlet opening for the water carrying the sand and an outlet opening for the oil.
  • hydrocyclone separators of the aforementioned type deposits on the surfaces of the individual hydrocyclones.
  • the interior of the chambers of the Hydrocyclone separators narrowed at the relevant points. This leads to a lower performance of the hydrocyclone separator.
  • the deposits eventually lead to that within relatively short intervals individual hydrocyclones or the entire hydrocyclone separator need to be replaced. This results in very frequent downtimes for those concerned Installations, which causes considerable costs.
  • a cleaning of the relevant parts from the deposits would require a very high level of chemical and abrasive Require detergents.
  • the invention is based, which in the known hydrocyclone separators and the exchange that becomes necessary individual hydrocyclones or the entire hydrocyclone separator to prevent or at least significantly reduce to achieve a longer service life.
  • the task is solved by one Hydrocyclone separator of the type mentioned in the that the surfaces of the individual hydrocyclones with a layer of a highly slidable and highly wear-resistant Plastic are provided.
  • the layer of highly slidable and highly wear-resistant Plastic causes it to surface on the hydrocyclones solid particles reaching the smooth Slip off the plastic layer and do not stick can.
  • the formation of deposits on the Prevents hydrocyclones As a result, they always remain original cross sections and thus the original Get flow rates. It is therefore in the extreme case only at very large intervals the hydrocyclones must be replaced.
  • PTFE polytetrafluoroethylene
  • the thickness of the layer expediently consists of highly slidable and highly wear-resistant plastic at least 8 ⁇ m, preferably about 17 ⁇ m.
  • the individual hydrocyclones before Applying the layer of a highly lubricious and highly wear-resistant plastic has a rough surface on.
  • the roughness is sufficient Surface of the individual hydrocyclones by appropriate mechanical processing, for example by to form a grinding process.
  • the roughness of the surface of the individual hydrocyclones can also be done in a simple manner by laser treatment or can be achieved by an etching process.
  • Hydrocyclone separators will increase the roughness of the Surface of the individual hydrocyclones by thermal Spraying of hard material granules achieved.
  • the hydrocyclone separator 1 shown in FIG. 1 has a first chamber 2 into which through an inlet opening 3 the oil-water-sand mixture enters.
  • Water can be sea water, for example.
  • the first chamber 2 there are a large number of individual ones Hydrocyclones 4, only a few of which are shown are.
  • the oil-water-sand mixture passes into the Hydrocyclones 4 provided openings 5 in the hydrocyclones 4, in which the oil from the sand-bearing water is deposited.
  • the sand-bearing water emerges from the ends of the hydrocyclones projecting into a second chamber 6 4 and thus first reaches the second Chamber 6. From there, the sand-bearing water is over disposed of an outlet opening 7.
  • the oil occurs on the other End of the hydrocyclones 4 and enters one third chamber 8. From there the oil is passed through a Discharge opening 9 deducted.
  • Fig. 2 In the hydrocyclone 4 shown in Fig. 2 is one Layer 10 made of a highly slidable and highly wear-resistant Plastic indicated by dash-dotted lines. As can be seen from Fig. 2, extends the layer 10 from the highly slidable and highly wear-resistant Plastic along the entire length of the Hydrocyclones 4.
