Description

Horizontal multi-stage separator
Technical field
The present invention relates to gas treatment equipment fields, and in particular to a kind of horizontal multi-stage separator.
Background technology
Natural gas refers to naturally contain the mixture of the hydro carbons and non-hydrocarbon gases in stratum.In petroleum geology, It is often referred to casing-head gas and reservoir gas.It is formed based on hydro carbons, and contains non-hydrocarbon gas.Natural gas is contained in underground porous gap rock In layer, including casing-head gas, reservoir gas, coal bed gas, gas of mud volcano and biology generation gas etc., also have on a small quantity for coal seam.It is excellent Matter fuel and industrial chemicals.
Natural gas is mainly used for making fuel, can manufacture carbon black, chemicals and liquefied petroleum gas, by natural gas production Propane, butane are the important source materials of modern industry.
In the gathering and transportation technology in natural gas production gas field, mined natural gas is usually with some liquid from gas well Body and solid impurity, such as condensate, condensation water, water flooding and landwaste dust, it is necessary to carry out gas-liquid in well site and gas gathering station (Gu)Separating treatment is separated them from natural gas.Therefore separator become natural gas production processing during Key equipment, it is desirable that separator separates light component, water and the impurity in natural gas as far as possible, reduces and is flowed into subordinate Journey avoids influencing normal production and safety.
At present, the Chinese patent of Publication No. CN104056503A discloses a kind of multipurpose horizontal natural gas separating and filtering Device, it includes cylinder, blind plate, blind plate retaining mechanism, and latch plate sliding cavity, blind plate are formed back to the one side of separating and filtering chamber in blind plate Retaining mechanism includes latch plate, center dish axle, spider, towing plate and spider operation handle, in spider back to the one of blind plate Side fixed center disk casing, spider casing is vertical with spider, is set on wall body of the blind plate back to the one side of separating and filtering chamber Cylinder pressure release response means are put, which is engaged with spider, in the circumferencial direction of blind plate mating interface And cleaning hole is opened up corresponding to the position of blind plate lock slots, sealing screw is arranged in cleaning hole.
Although this multipurpose horizontal natural gas separator-filter can fast and easily implement blind plate lock slots clear It is clean, but since natural gas is directly with filter core making contact, while need to control the ingress rate of natural gas, after practical for a long time Filter core is easily damaged, reduces its compressive resistance and filter efficiency, reduces filter effect.
The content of the invention
The object of the present invention is to provide a kind of horizontal multi-stage separators, and multistage filtering can be carried out by having, and be hardly damaged The advantages of filter core, raising filter efficiency and filter effect.
The present invention above-mentioned technical purpose technical scheme is that:
A kind of horizontal multi-stage separator, the end socket including cylinder and arranged on cylinder both ends, cylinder both sides be respectively equipped with inlet tube and Outlet, cylinder is interior to be equipped with by-pass filtration unit, secondary filtration unit and three-stage filtration successively from inlet tube to outlet direction Unit is isolated between by-pass filtration unit and secondary filtration unit by installing plate, if by-pass filtration unit include filter core and Dry root is circumferentially positioned at outside filter core for the flow-guiding bar for guiding natural gas to filter core, is additionally provided on installing plate and is penetrated installing plate and set It puts and connects the diversion pipe of secondary filtration unit, filter core is set on diversion pipe.
By using above-mentioned technical proposal, natural gas enters from inlet tube in separator, and passes sequentially through by-pass filtration list Member, secondary filtration unit and three-stage filtration unit are filtered, and in by-pass filtration unit, natural gas encounters flow-guiding bar and forms one Grade filtering, makes big impurity particle be separated under collision, also avoids natural gas and directly generates collision to filter core;Flow-guiding bar is by day Right gas is drained to filter core position, completes filtering, then enters secondary filtration unit by diversion pipe.
Natural gas can so be filtered three times, while impurity in natural gas will not be made to filter core direct collision, It cannot be easily caused the damage of filter core, additionally it is possible to improve whole filter efficiency and the filter effect to natural gas.
Further set:Filter core is set in truncated conical shape, and the one end being relatively large in diameter is set on diversion pipe.
By using above-mentioned technical proposal, air-flow can be drained on the smaller one end of filter core diameter by flow-guiding bar, be passed through The filtering of filter core, then by natural gas discharge to diversion pipe, make it into secondary filtration unit.Natural gas can be shunted, made It is preferably filtered.
Further set:Secondary filtration unit includes being arranged on the in vivo wire mesh demister of cylinder, and wire mesh demister is in disk form Shape, diameter are identical with the internal diameter of cylinder.
By using above-mentioned technical proposal, wire mesh demister can pool together the liquid in natural gas, and pass through Drain pipe on cylinder outwards discharges, and improves whole filter effect.
Further set:Tertiary filter includes the filter plate arranged on outlet position, and filter plate is arc-shaped shape setting, and card is set Below outlet, and it is embedded on cylinder inboard wall.
By using above-mentioned technical proposal, the setting of filter plate can achieve the effect that three-stage filtration, be embedded on inner wall Replacement of the personnel to filter plate can be conveniently operated, improves the filter effect of whole service life and entirety.
Further set:Cylinder is outer to be equipped with liquid trap towards ground one side, and drain pipe, by-pass filtration are communicated on liquid trap Unit, secondary filtration unit are equipped with the delivery pipe for connecting liquid trap with the cylinder body bottom of three-stage filtration cell position.
By using above-mentioned technical proposal, the liquid of filtering gained can be discharged into liquid trap by delivery pipe and deposit in natural gas It stores up and passes through drain line drains, personnel easy to operation discharge the in vivo sewage of cylinder.
Further set:Outlet is equipped with pressure gauge connection.
Further set:Inlet tube is located on cylinder towards the position of diversion pipe, and flow-stopping plate, baffle are fixed on diversion pipe Plate corresponds to inlet tube setting.
By using above-mentioned technical proposal, the setting of flow-stopping plate can stop inlet tube, avoid air-flow direct to pipeline It is impacted, the service life of pipeline can be extended, so as to improve filter effect.
Further set:Displacement pipe is communicated on the cylinder of by-pass filtration cell position, cylinder is by being arranged on the saddle of its bottom Seat supports.
By using above-mentioned technical proposal, cylinder can tively firm be supported by saddle, by replacing setting for pipe It puts personnel easy to operation and cleans cylinder.
In conclusion the invention has the advantages that:
Natural gas can be filtered three times, while the impurity in natural gas will not be made to filter core direct collision, it is not easy to be made Into the damage of filter core, additionally it is possible to improve whole filter efficiency and the filter effect to natural gas.
