The inwall of the following conical cavity of described rotor is provided with spirality and leads sand launder.
The excircle position of described rotor is set with the ultrasonic wave ring.
The sidepiece of described rotor and sand collecting hopper is provided with steam, the hot water channel hole that is communicated with well head steam, hot water feed pipeline, on steam, the hot water feed pipeline condenser is housed.
The sidepiece of described rotor and sand collecting hopper is provided with the reflux pipeline that is communicated with oil circulating pump.
The oil-out of described reflux pipeline be arranged in rotor following circular cone cavity.
Described sediment outflow assembly comprises sediment outflow pipeline, electromagnetic valve and sediment outflow pump, and wherein, electromagnetic valve and sediment outflow pump are contained on the sediment outflow pipeline, and the sediment outflow pipeline is communicated with contaminated-oil basin.
The bottom of described contaminated-oil basin is provided with sand export, and top is provided with the oil return pipeline, and this pipeline is communicated with described reflux pipeline.
Centrifugal well head sand-hog according to the such scheme making, adopt the mode of carrying out desanding again behind the heating viscosity reduction, can remove rove grain and particulate in the crude oil effectively, thereby improve the transfer efficiency of crude oil greatly, guarantee the unimpeded of oil pipeline, prolonged the application life of petroleum pipeline and pump, realize that well head is online, the purpose of airtight desanding, and realized non-pollution discharge.This desander has simple in structure, reliable, easy to operate, and desanding effect is good, efficient is high and personnel, equipment are also as safe as a house, does not have any accident potential.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1.
The specific embodiment
Referring to Fig. 1, centrifugal well head sand-hog of the present utility model, form by rotor 3, last main body 12 and following main body 2, wherein, last main body 12 closely is connected by flange, securing member with following main body 2, and its axis part is a cylindrical housings, and rotor 3 is installed in this housing by bearing 16,17 and seal, and can rotate freely, the top of last main body 12 is connected and is communicated with removing the liquid pipeline by adpting flange 13.Rotor 3 is a cylindrical structural, is connected with driving mechanism 11 with the driving gear 9 that is engaged with by the gear ring 10 that installs on its excircle.The axis part of rotor 3 has and is the cavity of bell mouth shape up and down, and forms last circular cone cavity and the following circular cone cavity that is interconnected, and wherein descends to have spirality on the circumferential wall of circular cone cavity and lead sand launder.Rotor 3 is rotation at a high speed under the drive of driving mechanism 11, forms centrifugal force thus, and the oil-sand of its inner chamber is separated with fluid.The bottom of rotor 3 is provided with and following main body 2 close-connected sand collecting hoppers 1, rotor 3 and the corresponding respectively oil inlet passage hole that is provided with and comes liquid pipeline 7 to be communicated with of a side of upper and lower main body 12,2 and the hole, return flow line that is communicated with reflux pipeline 6, the opposite side correspondence offers steam, the hot water channel hole that is communicated with well head steam, hot water feed pipeline 20, in the fluid of rotor 3 inner chambers, to add steam injection or hot water, make fluid dilution, be convenient to separating of oil-sand and fluid.Sand collecting hopper 1 is a column structure, and its axis part has cup-shaped cavity, with the corresponding connection of inner chamber of rotor 3.The bottom of sand collecting hopper 1 is connected with sediment outflow assembly 22, and this assembly comprises sediment outflow pipeline 23, electromagnetic valve and sediment outflow pump (not shown), and wherein, electromagnetic valve and sediment outflow pump are contained on the sediment outflow pipeline 23, and sediment outflow pump and sediment outflow pipeline 23 are communicated with contaminated-oil basin 4.One side of sand collecting hopper 1 is provided with the through hole that is used to install reflux pipeline 6, and the liquid outlet of reflux pipeline 6 puts in the following circular cone cavity of rotor 3, and reflux pipeline 6 is communicated with oil circulating pump 8.The opposite side of sand collecting hopper 1 is provided with two access openings that are communicated with steam, 20 parallel connections of hot water feed pipeline, and the steam between the two passes hole, hot water feed pipeline 20 are provided with condenser 21, are used for the oil-sand in the sand collecting hopper 1 is diluted, and are convenient to the discharge of oil-sand.Be connected with the oil return pipe 5 that is communicated with reflux pipeline 6 by sump (waste oil) pump on the contaminated-oil basin 4, the backflow of the sump oil after the precipitate and separate can be entered rotor 3 and separate once more.Defeated for the collection that makes the unlikely harm fluid of contained trickle sand grains in the fluid after desanding is handled, can on eddy flow gas device 3 top excircles, install the ultrasonic wave ring additional, utilize hyperacoustic vibration, the little sand grains that is wrapped in the crude oil is removed.Number in the figure the 15, the 18th, bearing gland, label the 14, the 19th, body end cap.
Operating principle: sand-hog of the present utility model is fixedly mounted on shaft mouth side, it comes liquid pipeline 7 ends to be connected with the well head drain pipe, go liquid pipeline end to be connected with crude oil gathering pipelines, the crude oil of extraction can enter the following circular cone cavity of rotor 3, start driving mechanism 11, drive rotor 3 fast rotational by driving mechanism 11 by gear driving member, under its action of centrifugal force, sand in the fluid is separated, and lead sand launder by spiral and enter in the sand collecting hopper 1, and separated liquid oil under the pressure effect of rotary floating and bottom feed liquor through on the liquid outlet of circular cone cavity and last main body 12 enter crude oil gathering pipelines.The oil-sand of deposition can enter to staticly settle in the contaminated-oil basin 4 and separate by regular opens solenoid valve and sediment outflow pump in the sand collecting hopper 1.In order to guarantee the fluid tar sands not after desanding is handled, the bottom of circular cone cavity bigger the containing sand fluid and can be back to again in the following circular cone cavity of rotor 3 by reflux pipeline 6 and carry out the secondary centrifuging desanding of proportion nearby on the rotor.The crude oil that oil-sand is with that enters contaminated-oil basin 4 is after precipitate and separate, and its upper strata fluid can carry out centrifugal desanding by oil return pipe 5 and through reflux pipeline 6 together enters the following circular cone cavity of rotor 3 with backflow fluid in again.When carrying out thickened oil recovery or extraction fluid viscosity is bigger, when oil-sand is not easily separated, can heats or inject hot water and dilute by steam, hot water feed pipeline 20 steam in jections, be convenient to that oil-sand separates and sand collecting hopper 1 in oil-sand mobile.Through centrifugal branch
Still can contain tiny little sand grains in the fluid after desanding, can be on the excircle on rotor 3 tops suit ultrasonic wave ring, with the little sand grains fragmentation of oil-containing, can avoid collecting the line clogging in the defeated process and the damage of booster pump by ultrasonic wave.
