Description
Technical field
The utility model relates to the checkout equipment of oil field cargo tank toxic gas, maybe needs to detect the filtration extend neck of hydrogen sulfide measuring instrument used in the platform cargo tank of hydrogen sulfide toxic gas especially for the gauging cabin on the FPSO of oil field.
Background technology
FPSO is a kind of production, storage, outer defeated floating production storage unit of collecting.From the crude oil of wellhead platform extraction, enter oil cargo tank through the processing of oil gas water and store, but in oil, can follow the volatilization of some toxic gases, or have entering of toxic gas in the coating gas in large cabin, can cause containing in cabin a large amount of toxic gases.Wherein hydrogen sulfide gas is the gas of tool harmfulness, for the moment is understood the gas-condition in the cabin of each oil storage, just needs carry out the detection of toxic gas to the young oil entering in large cabin every day, takes precautions against in possible trouble and prepares.Now utilize hydrogen sulfide tester to carry out determining of content to the hydrogen sulfide gas in large cabin.Often contain the oil droplet of liquid-in-gas from oil tank hatch gas out, due to the saturated positive air pressure in large cabin, while detecting hydrogen sulfide, gas can be taken a large amount of drops out of, and because hydrogen sulfide tester is very accurate and expensive, entering of liquid can damage instrument, again in conjunction with the actual conditions of field produces and maintenance, filter extend neck so now just need to design one between hatch and instrument, offshore oilfield is surveyed in the operating type of hydrogen sulfide in the past, there is no the use of this type of instrument.The way generally adopting is in the past that before measuring, operating personnel need wear gas mask at every turn, is with good clean rag, manually blocks the gauge hatch in large cabin with hand-held firmly rag, then the OD joint of instrument valve is placed on to the method for measuring on rag.In measuring process because large cabin noble gas malleation covers, the artificial method sealing of rag that uses is very poor, having oil-containing gases sprays outward, hydrogen sulfide gas also can overflow in a large number, rag and hand are made dirty by oil gas, and overflowing of hydrogen sulfide can affect other operating personnels' safety around, and dangerous and inconvenient method.
Through retrieval, do not find to be applied to filter plant in FPSO hydrogen sulfide measuring instrument.
Summary of the invention
The invention provides and a kind of filter extend neck for FPSO hydrogen sulfide measuring instrument, its object is to simplify the step that hydrogen sulfide is measured, and improves the efficiency that hydrogen sulfide is measured, and the raising economy that cuts down expenses, and safety while guaranteeing that operator measures, reduce operation on the sea risk.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of filtration extend neck for FPSO hydrogen sulfide measuring instrument, it is to be made up of filtering head, gas-liquid separation sleeve and cargo tank joint, described filtering head is mainly made up of joint and cartridge filter, one end of cartridge filter is connected with joint, the other end is connected with one end of gas-liquid separation sleeve, and cargo tank joint is connected with the other end of gas-liquid separation sleeve; Described joint is connected with the air inlet pipe of hydrogen sulfide measuring instrument, and the gauge hatch of described cargo tank joint and cargo tank is tightly connected.
Described gas-liquid separation sleeve is to be made up of cylindrical shell, three gas-liquid separation dividing plates and a circular gas-liquid separation plate, described three gas-liquid separation dividing plates are staggered spaced apart along axis direction in cylindrical shell, the surface of described circular gas-liquid separation plate has multiple through holes, and circular gas-liquid separation plate is located in cylindrical shell and is positioned at the top of three gas-liquid separation dividing plates.
The two ends of described gas-liquid separation sleeve are provided with internal thread, and one end of described cartridge filter is connected with the threaded one end of gas-liquid separation sleeve, and the other end is connected with cargo tank joint screw thread.
In the connector of described joint, be provided with internal thread, cartridge filter is threaded with the connector of joint.
Described joint adopts OD joint.
The beneficial effects of the utility model: owing to adopting above-mentioned version, without using breathing mask, rag, only need alignment to connect gauge hatch, greatly save the activity duration, also can save operating cost, improve operating personnel's security, extend the service life of measuring instrument.
