Spherical pig transmitter 6 has service cylinder, between service cylinder and the end of conveyance conduit 7, is connected adjustable pipe; Spherical pig receiver 9 has ball collecting chamber, between ball collecting chamber and the end of conveyance conduit 7, is connected adjustable pipe.The two ends of conveyance conduit 7 are used respectively elbow to be connected with straight tube, connect one section of straight adjustable pipe between elbow and service cylinder or ball collecting chamber.The logical ball equipment being made up of spherical pig transmitter 6 and spherical pig receiver 9, will bear in ball outlet and ball drain port place the thrust necessarily being transformed by pressure, therefore this structure on two sides need carry out certain reinforcing, in case pipeline displacement occurs or be out of shape because of stressed when stop-pass ball.
In conveyance conduit 7, evenly arranged and establish some spherical pigs 8 to spherical pig receiver 9 by spherical pig transmitter 6, this spherical pig 8 is straight slab bowl mixed type wiper.These spherical pigs 8, under the promotion of current, and are cleaned inboard wall of tube body along directed walking at uniform intervals one by one, until the water body that drainpipe 10 flows out meets cleanliness standard.
The operation process of the purging system of this seabed feed-line is:
(1) water intaking: again check before water intaking that whether storage tank 3 water inlets place are unobstructed, whether all energising circuits are normal, confirm errorless after give immersible pump 2 switch on, to the interior retaining of storage tank 3, flow-rate ratio flushing pump 4 flows of immersible pump 2 are large, meet the not requirement of empty water in storage tank 3, superfluous water adopts skirt to draw water tank.
(2) water filling, logical ball: after water filling completes, casing 3/4 place that water level arrives storage tank 3 suspends water filling, opens the outlet valve of flushing pump 4, opens the ball valve of spherical pig transmitter 6 water inlets simultaneously, starts flushing pump 4 to the interior water filling 30m of conveyance conduit 7
3left and right, the logical ball of order.
(3) draining processing: after logical ball starts, because conveyance conduit 7 is longer, therefore receipts pommel receives the time of water or foreign material and has a time difference, can constantly have Bas Discharged but receive pommel in the injecting process, should guarantee that discharge outlet, air bleeding valve are all in opening-wide state by special messenger's monitoring.Should, first by ball collecting chamber exhaust valve closure, only stay discharge outlet to carry out rinse water discharge when receiving after the water outlet of pommel.Rinse water will be discharged after treatment again, guarantees can not pollute natural environment.
(4) receive ball: receive after first spherical pig 8 when receiving pommel, service end stops flushing pump 4, opens ball collecting chamber and takes out the rear recovery of spherical pig 8, continues logical ball, spherical pig 8 below receives according to above program and repeats, until the water body that drainpipe 10 flows out meets cleanliness standard.
(5) criterion of acceptability: for guaranteeing clean the dirt removal in conveyance conduit 7, in pigging process, pigging operation is no less than 2 groups of balls, and the foreign material volume that last piece of spherical pig 8 clears out is no more than 5L or discharges solid matter and is no more than 0.1L/km, measure the spherical pig 8 using and there is no gross distortion and obvious cut, if cleannes do not reach requirement, increase time of pigging.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendments or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although more used fixed support 1 herein; Immersible pump 2; Storage tank 3; Flushing pump 4; Blind plate 5; Spherical pig transmitter 6; Conveyance conduit 7; Spherical pig 8; Spherical pig receiver 9; Drainpipe 10; Treatment tank 11 terms such as grade, but do not get rid of the possibility that uses other term.Use these terms to be only used to describe more easily and explain essence of the present utility model; They are construed to any additional restriction is all contrary with the utility model spirit.
