Abstract
A nozzle for use with a pressurized water source as typically used in the offshore environment. The nozzle attaches to a hose or fixed work pipe installation and provides a channel through a body, on which is arranged a frusto-conical fluid deflector. Fluid flowing along the channel may impinge upon the fluid deflector and may travel along a surface of the deflector and out of the nozzle in a jet. Various embodiments are described for varying the width of the channel at the deflector to adjusting, a characteristic of the jet and for providing self-cleaning of the nozzle. Further a central channel is described which allows an additional nozzle to be included as are sensors which determine pressure, temperature and the like in the nozzle.
Claims27
A nozzle for a hose or fixed pipework installation, the nozzle adapted for forming a wall of fluid adjacent to a flare in a hydrocarbon well test operation and comprising:
- a body defining a channel therethrough, the body further defining a central beam or projection which extends into the channel;
- a fluid deflector attached to the central beam or projection, the fluid deflector having a deflecting surface;
- wherein the fluid deflector is arranged at or near a downstream end of the channel such that the deflecting surface and the body together define a circumferentially continuous outlet, the downstream end of the channel comprises a chamfered surface oriented substantially parallel to the deflecting surface, and the deflecting surface extends beyond an outer width of the body;
- and
- a spacer ring disposed in a gap or space between the fluid deflector and a shoulder of the body to alter the position of the fluid deflector relative to the downstream end of the channel, thereby varying the width of the outlet.
A kit of parts for a nozzle for forming a water wall adjacent to a flare in a hydrocarbon well-test operation, the kit of parts comprising a body which defines a channel extending therethrough, the body further defining a central beam or projection which extends into the channel, a fluid deflector having a deflecting surface, a coupling to connect the fluid deflector to the body, and a spacer ring to alter the position of the fluid deflector relative to the body, wherein the kit of parts when assembled forms the nozzle wherein:
- the fluid deflector is attached to the central beam or projection using the coupling;
- the fluid deflector is arranged at or near a downstream end of the channel and the deflecting surface and the body together define a circumferentially continuous outlet;
- the downstream end of the channel comprises a chamfered surface oriented substantially parallel to the deflecting surface;
- the deflecting surface extends beyond an outer width of the body;
- and
- the spacer ring is disposed in a space or gap between the fluid deflector and a shoulder of the body, thereby varying the width of the outlet.
A nozzle for a hose or fixed pipework installation, the nozzle adapted for forming a wall of fluid adjacent to a flare in a hydrocarbon well test operation and comprising:
- a body defining a channel extending therethrough, the body further defining a central beam or projection which extends into the channel such that the channel comprises a main channel portion upstream of the central beam or projection and a generally annular channel portion around the central beam or projection at a downstream end of the channel;
- a fluid deflector having a deflecting surface wherein the fluid deflector is attached to the central beam or projection, the fluid deflector is arranged at or near a downstream end of the channel such that the deflecting surface and the body together define a circumferentially continuous outlet, the deflecting surface extends beyond an outer width of the body, and wherein a maximum diameter of the generally annular channel portion is greater than a maximum diameter of the main channel portion;
- and
- a spacer ring disposed in a gap or space between the fluid deflector and a shoulder of the body to alter the position of the fluid deflector relative to the downstream end of the channel, thereby varying the width of the outlet.
A nozzle for a hose or fixed pipework installation, the nozzle adapted for forming a wall of fluid adjacent to a flare in a hydrocarbon well test operation and comprising:
- a body defining a channel extending therethrough;
- a fluid deflector having a deflecting surface and a central beam or projection which extends from the deflecting surface into the channel,
- wherein the fluid deflector is arranged at or near a downstream end of the channel such that the deflecting surface and the body together define a circumferentially continuous outlet, the central beam or projection is attached to the body upstream from the circumferentially continuous outlet, the downstream end of the channel comprises a chamfered surface oriented substantially parallel to the deflecting surface, and wherein the deflecting surface extends beyond an outer width of the body;
- fins extending between the central beam or projection of the fluid deflector and the body, wherein the fins secure the fluid deflector to the body;
- a coupling ring attached to the body to secure the fins in place;
- and
- a fixed ring or a spacer ring located between the coupling ring and the fins to position the deflector within the body.
A nozzle for a hose or fixed pipework installation, the nozzle adapted for forming a wall of fluid adjacent to a flare in a hydrocarbon well test operation and comprising:
- a body defining a channel extending therethrough;
- a fluid deflector having a deflecting surface and a central beam or projection which extends from the deflecting surface into the channel so as to define a main channel portion upstream of the central beam or projection and a generally annular channel portion around the central beam or projection at a downstream end of the channel;
- wherein the fluid deflector is arranged at or near a downstream end of the channel such that the deflecting surface and the body together define a circumferentially continuous outlet, the central beam or projection is attached by fins to the body upstream from the circumferentially continuous outlet, the deflecting surface extends beyond an outer width of the body, and a maximum diameter of the generally annular channel portion is greater than a maximum diameter of the main channel portion;
