Description
Technical field
The utility model discloses a kind of gathering line corrosion inhibiter coating device, especially for the corrosion inhibiter coating device of high sulfur-bearing moisture gathering line.
Background technology
In gas industry, the function of moisture gathering line is further to process transporting to gas treatment factory without the natural gas of separation and purified treatment in the gas gathering station.Between pipeline and the external environment condition heat exchange can occur in the moisture course of conveying, a part is recombinated branch's condensation out when the heat conduction makes tube wall temperature be lower than the steam dew point, thereby produces hydrops.For the acid gas pipeline that contains hydrogen sulfide and carbon dioxide, having under the hydrops existence condition, can cause the electrochemical corrosion that pipeline is serious, cause tube wall attenuate even perforation, thereby cause poisonous medium to leak, and then cause poisoning or the accidents such as fire, blast.In the actual industrial production usually employing regularly carry out the method that pipeline corrosion inhibitor films and prevent pipeline corrosion.Namely by the corrosion inhibiter of annotating in pipeline, corrosion inhibiter is fully contacted with inside pipe wall, corrosion inhibiter is by special close metallicity chemical b `, and meeting and the strong combination of pipe inner metal surface form layer protecting film.Usually adopt two wipers when tube wall is filmed, corrosion inhibiter is annotated between former and later two wipers, forms the liquid plug of a sealing.Two wipers in the wings under the gas push at walking in pipe, the corrosion inhibiter liquid plug that is enclosed between two wipers contacts with tube wall, thereby tube wall is filmed.But in the actual operation process of filming; because wiper kinetic characteristic in pipeline is subjected to various factors; former and later two wiper speeds of service are often inconsistent; when the place ahead wiper speed of service during greater than the rear wiper; spacing between two wipers of front and back can increase; the corrosion inhibiter that be enclosed between two wipers this moment will no longer be full of whole pipeline; but generation layering; thereby cause the top tube wall owing to failing to contact with corrosion inhibiter; can not form diaphragm; therefore the corrosion rate of overhead line produces so-called pipeline top part corrosion much larger than the pipeline bottom.
US Patent No. 6874193 proposes a kind of ejection-type corrosion inhibiter coating device.This device core component is mounted in the Venturi nozzle of head, and Venturi nozzle and device afterbody are communicated with.When the wiper backside gas arrives Venturi nozzle; because circulation area is dwindled suddenly; fluid is accelerated; to produce negative pressure according to bernoulli principle; cause parital vacuum; thereby the liquid that is deposited on the pipeline bottom is carried via the liquid suction tube enters nozzle, carried secretly to tube wall top by air-flow and spray, the corrosion inhibiter coating protective is carried out on pipeline top.But in use there are the following problems for this device: the one, because the wiper backside gas constantly enters two enclosure spaces that wiper forms, thereby two wiper spacings are increasing before and after causing, the liquid height that is enclosed in therebetween is more and more lower, it is also increasing that liquid enters the difficulty of nozzle, even entirely ineffective; The 2nd, wiper may rotate in running, thereby causes nozzle ejection position deviation pipeline top, thereby causes the tube wall top may not receive atomizing of liquids; The 3rd, the amount of liquid that sprays is subjected to the various factors such as pipeline backside gas flow velocity, pipeline structure, can't keep constantly, can not guarantee pre-film quality.
Article " top part corrosion of moisture pipeline and protection " (corrosion and protection, the 4th phase of the 28th volume in 2007: 167-170) mentioned a kind of rotary-type coating device.This device is a cylinder, periphery is processed with many spiral grooves, when device was advanced by gas push in pipeline, the air-flow in the spiral groove can promote spreader and ceaselessly rotate, thereby the liquid phase corrosion inhibiter that will be filled into duct bottom takes the pipeline top to.In fact, because the frictional resistance between wiper and the inside pipe wall is quite large, wiper is difficult to rotate in running, bottom liquid can't be carried to the top, therefore can't be applied in the actual production.
Patent of invention CN 102266838 discloses a kind of gathering line corrosion inhibiter coating device, by battery compartment, and motor bin, impeller forms, and blade is installed on the impeller, and impeller rotates under motor-driven, by blade pipeline bottom corrosion inhibiter is carried to the pipeline top, covers whole inner-walls of duct.The method adopts the battery driven motor rotation, and limited by battery capacity its running time, is difficult to be applicable to the long gathering line of distance.Simultaneously, because device exists electrical equipment to connect, explosion-proof is had higher requirements, carrying inflammable, explosive gathering line use to have potential safety hazard.
