Definitions

  • This invention relates to a high efficiency separator with an anti-flush device for light liquids of specific gravity less than water. Interceptors are currently used within a drainage system to separate and retain accidental spillages of hydrocarbons.
  • a light liquid separator comprising a storage tank with an inlet at high level connected to an inlet chamber with a high level outlet pipe connected at low level to an outlet chamber which is set below a valve chamber with a spherical specific gravity sensitive valve floating freely inside the valve chamber above an annular seat with a coalescing filter tube fitted around the valve chamber.
  • figure 1 shows the interceptor with the removable valve chamber assembly in the working position.
  • the separator comprises a storage tank (12) with an inlet piped) at high level. This inlet piped) discharges into an inlet chamber (18) which reduces the velocity of the incoming liquid and promotes lamina flow.
  • a valve chamber assembly (13) is attached by sliding brackets(17) to a guide shaft (5) near to the outlet end of the storage tank (12).
  • the sides of the valve chamber (16) have a series of large slots to allow the free passage of water.
  • Around the outside of the valve chamber (16) a coalescing filter tube(2) is incorporated.
  • a handle (11) extends from the top of the valve chamber assembly (13) to the top of the access turret (10) and has a locking device(15) at the top.
  • At the base of the valve chamber assembly (13) is a tapered seat (7) against which a floating ball shaped valve(4) can seal. The floating ball shaped valve(4) is retained within the valve chamber (16) by a lid(9).
  • valve chamber assembly(13) sits on a tapered seat (3) set in the top of the outlet chamber (8).
  • the outlet chamber (8) is connected to the bottom of the outlet pipe(6).
  • the high efficiency anti-flush light liquid separator will operate in the following manner : -
  • Water and light liquids e.g. oil and or petroleum
  • Water and light liquids will enter the storage tank(12) through the inlet piped), to the inlet chamber which will direct the incoming flow significantly below the natural liquid level inside the storage tank(12).
  • the flow is introduced at such an angle as to cause the retained liquids to slowly rotate in a horizontal lamina flow.
  • the velocity of the incoming liquid is reduced gradually thereby eliminating virtually all turbulence allowing previously collected light liquids to remain as a continuous layer floating on the surface of the water.
  • a ball shaped valve(4) which has a specific gravity between that of a specified light liquid (e.g. oil or petroleum) and water. It will therefore float in water but sink in the light liquid.
  • a specified light liquid e.g. oil or petroleum
  • the layer of separated light liquid at the top of the tank will thicken and the boundary between the light liquid and the water will move down the tank.
  • the ball shaped valve(4) will sink until it seals against the seat (7) at the base of the valve chamber assembly (13). This will then prevent any further discharge from the separator.
  • a mechanical catch (15) is positioned at the top of the guide shaft (5) which, when released allows the valve chamber as ⁇ embly(13) to be withdrawn from the storage tank(12).
  • the valve chamber assembly(13) When the valve chamber assembly(13) is returned to it's working position, it seals against a tapered seat (3) on the top of the outlet chamber (6).
  • the valve chamber assembly(13) is retained in position by resetting the mechanical catch (15).
