Fig. 9 is the structural representation that pipeline cleanser of the present invention is followed the tracks of bullet.
The specific embodiment
With reference to Fig. 1.Pipeline cleanser shown in Figure 1 comprises that pressure source, the pneumatic supply 1 be made up of pneumatic supply 1 and hydraulic power source 2 are formed by connecting by air compressor 11, electrically-controlled valve 14, gas tank 12 and air cutoff valve 13 usefulness pipelines.On the pipeline between gas tank 12 and the air cutoff valve 13, pressure sensor 15 is housed, temperature sensor 16.Hydraulic power source 2 is formed by connecting by water pump 21, electrically-controlled valve 24, water storing tank 22, water stop valve 23 usefulness pipelines.Water pump 21 can be selected the sectional type centrifugal multistage pump multiple centrifugal pump for use.Pressure sensor 25, temperature sensor 26 and flow sensor 27 are housed on the pipeline between water storing tank 22 and the water stop valve 23.Electrically-controlled valve 14,24, pressure sensor 15,25, the holding wire of temperature sensor 16,26 and flow sensor 27 is connected with controller 10 respectively.Controller 10 is analyzed the signal that various sensors record, and calculates back control electrically-controlled valve 14 or 24 and opens pneumatic supply 1 or hydraulic power source 2.Pressure source is connected with 9 with the efferent duct 3 of two parallel connections.Efferent duct 3 is connected by the fluid intake 45 of stop valve 31 with the transmitting tube 44 of the emission cavity 41 that cleans ball emitter 4.At the construction field (site).Be earlier the top of pipe to be treated 8 to be severed, the centre plug with holes of burn-oning then makes efferent duct 9 be connected with pipe to be treated 8.Clean ball emitter 4 and weld together, so that make the cleaning bullet send into pipe to be treated 8 smoothly from oblique side direction and pipe to be treated 8.Clean ball emitter 4 by emission cavity 41 with shoot cabin 42 and forms, middle with globe valve 43 connections.Can hold 2 pieces of bullets simultaneously in the transmitting tube 44 of emission cavity 41.Under the situation of holding 2 pieces of bullets, normally will hereinafter will describe one piece with the cleaning bullet of low frequency generator with the tracking bullet that only has low frequency generator and do not have the cutting tool use that bonds together.Shoot cabin 42 and make taper usually, its bore is slightly larger than the cleaning bullet.Open ball valve 43 during use and will clean bullet and send in the transmitting tube 41, close ball valve 43 then and prepare emission.
With reference to Fig. 2 and Fig. 3.Fig. 2 and Fig. 3 represent the front view and the cross-sectional view of spiral knife-edge cleaning bullet respectively.Cleaning bullet 5 mid portions is matrix 51, and it is the 0.06-0.15 gram per centimeter by density
3Polyurethane foam plastics make, matrix 51 is soft.Glued joint the outside of matrix 51 has one deck by polyurethane-polyurea or polyurethane-epoxy resin-bicomponent structure type polyurethane layers 52 such as polyureas, and its thickness is the 15-20 millimeter.The cutting tool 53 that helical pattern is arranged is gluedd joint in outside at layer of polyurethane 52, and cutting tool 53 is made by impact-resistant alloy steel or wear-resisting alloy steel or alloy spring steel etc.Spirality can be right-hand screw and also can be left-hand screw, in the matrix 51 that cleans bullet 5 the low frequency generator (not shown) is housed.The supporting use of using on low frequency generator and the ground of removable low frequency signal receiver is cleaned the position of bullet 5 in pipe to be treated 8 so that measure.
With reference to Fig. 4-Fig. 9.Fig. 4 and Fig. 5 represent that cutting tool is the cleaning bullet of scopiform, and Fig. 6 and Fig. 7 represent that cutting tool is that knife-edge in upright arrangement is cleaned bullet, and Fig. 8 represents that cutting tool is the cleaning bullet of convex concave.Harder for pipeline scale, thicker should select for use spiral knife-edge or knife-edge in upright arrangement are cleaned bullet; Softer to fouling, the thicker scopiform of should selecting for use is cleaned bullet, before thin or pipeline is about to clean and will finish to fouling, should select for use convex concave to clean bullet.Cleaning the diameter of bullet should be determined according to diameter and thickness of structure, character, the state of the pipeline that is cleaned, generally than the big 12-20% of average fouling diameter, and last the cleaning, cleaning the bullet magnitude of interference must not be greater than 12%.Fig. 9 is a structural representation of following the tracks of bullet, follows the tracks of bullet and is which is provided with bonding cutting tool with the difference of cleaning bullet, adds low frequency generator 30 in the inside of matrix.When being cleaned the less or crooked radian of pipeline internal diameter hour, in its matrix, install low frequency generator because of cleaning the long-pending less inconvenience of body additional, the tracking bullet that has low frequency generator can be bonded in this moment to clean and play the back, in cleaning the de-sludging process, follow the tracks of bullet and move together, so that determine to clean the position of bullet in being cleaned pipeline by the low frequency signal receiver of outside with cleaning bullet.
The pipeline cleanser course of work of the present invention is as follows:
Before to the pipeline washing and cleaning operation, as to pipeline trend, curved number of spots and radian etc. when indeterminate, should take following program: earlier with the pipeline both ends open that is cleaned, cleaning ball emitter 4 shown in Figure 1 in the head end welding is installed contaminants collector 6 endways and is cleaned bullet receiver 7.Usually pressure source, contaminants collector 6 and cleaning being played recover 7 installs on the ground.With the washing test bullet of the suitable specification transmitter 4 of packing into, start compressor 11, open gas tank 12 and control section, accurately control and gaging pressure, until the washing test bullet till the recover of the pipeline other end reclaims.The purpose of above-mentioned test mainly is that the adaptability of bullet and the road ability of bend are cleaned in checking, obtains to clean to play thrust, and item number certificates such as the speed of service prevent to occur in the cleaning process blocking the bullet accident of cleaning.
When pipeline is carried out washing and cleaning operation, at first should determine the material of pipeline, the design pressure-bearing, carry which kind of fluid, discharge pressure, the pipeline trend, the discrepancy in elevation, buried depth, the elbow radian, service time etc. data, again according to caliber, foulant state and character, thickness determines to be cleaned the each length of cleaning of pipeline (general length should be determined at 1KM-5KM), to clean the bullet transmitter of packing into then, select to promote to clean the power source (pneumatic supply or hydraulic power source) of bullet work and promote medium (water or air), start pneumatic supply or hydraulic power source, accurately controlled pressure, (flow), promote medium and clean bullet in the pipeline that is cleaned, to produce friction, cutting waits effect to remove all kinds of foulant.
Higher to foulant hardness, the pipeline that dirty matter is thicker should adopt the way that increases cleaning bullet bore gradually repeatedly to clean in reality is cleaned.
Pipeline scaling thing composition complexity, the two kinds of different types of cleaning bullets of transmitter of can once packing into.
Conditions permit, former pumped (conveying) medium do not have inflammable, explosive danger also can promote to clean bullet work as power source with former pumped (conveying) medium.
According to measuring, the safe operation speed of cleaning bullet in being cleaned pipeline can not be lower than 8 times of foulant free-falling velocity, and the work speed of service of promptly cleaning bullet is between the 0.9-1.9m/s.The speed of service is too slow or be in operation and stop cleaning bullet to occur and be stuck in the danger that is cleaned in the pipeline at work to clean bullet.
Tube cleaning arrangement of the present invention is applicable to the pipeline that cleaning is more straight, to repeatedly reducing, threeway, bypass pipeline more, in confused situation can not clean.Tube cleaning arrangement of the present invention can be used for cleaning oil transportation, water delivery, sewer line, also can be used for the cleaning of pipelines such as natural gas.
