Description
Technical field
The utility model relates to pipeline cleaning technical field, and more particularly, the pollution-free high-efficient long-distance pipe that relates to a kind of wiper-synchronous passivation and degreasing construction is installed purging system.
Background technology
Pipeline can form during in rolling and roll skin at raw material steel pipe, steel plate, stainless steel etc.; Pipeline can form iron rust, welding slag and be the anticorrosion oily antirust agent being coated on pipeline, the impurity such as dust, sand, cement, insulation material in manufacture, accumulating and installation process.Above-mentioned normal use of rolling the various impurity such as skin, iron rust, welding slag, antirust agent and silt and have a strong impact on pipeline, therefore needs pipeline to clean, and makes to recover in pipeline material itself surperficial.
The method of existing pipeline cleaning mainly contains three kinds: 1, Chemical cleaning, Chemical cleaning pipeline is to adopt chemical agent, pipeline is carried out to interim transformation, carry out cyclic chemical cleaning from two of pipeline with temporary pipeline and water circulating pump station, before cleaning, will select cleaning agent for different equipment; Chemical cleaning, the rectifying column coke removal that mainly contains oilfield flooding pipeline network cleaned, long-distance transport pipes oil changes the number of chemical pipeline cleanings such as chemistry is cleaned, the front cleaning of industrial pipeline use, it is strong that this technology has flexibility, to pipe shape no requirement (NR), speed is fast, clean the features such as thorough, but also possesses following shortcoming: need a large amount of chemical cleaning solutions, and a large amount of cleaning fluids certainly will will cause a large amount of wastes and environmental pollution.2, high pressure water cleaning, adopts high-pressure water jet more than 50Mpa, inner surface of pipeline dirt is carried out to high-pressure water jet and peel off cleaning; Features such as it is fast that this technology has speed, and cost is low, but be mainly used in short distance pipeline, and more than pipe diameter must be greater than 50cm.3, PIG pigging: PIG pipeline cleaning system is mainly by PIG, PIG transmitter, PIG receiver, relevant detection system, power source and promote medium composition, PIG industry pigging technology is to rely on the motive force that pump propelling fluid produces to drive PIG (wiper) to promote forward in pipe, the scraping facility of PIG and wearing thereof will be piled up outside the dirt discharge pipe of in-line, thereby reaches the object of cleaning; This technology is widely used in the cleaning work such as all kinds of process pipes, oil field oil transportation gas pipeline, particularly carries the pipeline cleaning of fluid for long distance, has the irreplaceable advantage of other technologies.
At present domestic and international oil, chemical industry, natural gas, in the engineerings such as water supply conveyance system especially for air, oxygen, nitrogen, the cleanliness factor of the inner-walls of duct of hydrogen and various gases requires quite high, every profession and trade, company standard all has special special description to this, therefore, ensure that after installing, the cleanliness factor of inner wall of long-distance pipe is most important, traditional construction method is to adopt above-mentioned chemical cleaning method or PIG pigging method to use separately, in view of traditional chemical method needs a large amount of chemical cleaning solutions, and cause a large amount of wastes and environmental pollution to be replaced by PIG pigging method gradually.
Existing a large amount of method of utilizing PIG wiper pigging in prior art, as being published in " practical technique " the 13rd the 1st phase of volume " Pig pigging technology and application thereof ", author Niu Zhongyou in February, 1997; And for example within 2003, be published in " PIG cleaning technique changes the application on gas pipeline at oil " of " the cleaning world " the 19th volume o. 11th, author Wang Zhongtai, Liu Wenshan, Zhou Tianping, Zhang Henglu; And for example be published in " the cleaning world " the 21st the 1st phase of volume " PIG cleaning technique is in the ducted application study of reactor decommissioning " in January, 2005, author Wang Donghai, is all the methods that use separately PIG pigging.
In partial oxidation, the project under construction of nitrogen length apart from feed-line, relate to the inflammable and explosive media such as oxygen, according to national industry standard " degreasing engineering construction and acceptance specification " HG 20202-2000 requirement, must carry out degreasing operation; According to relevant regulations in national industry standard " construction of oil gas engineering in pipeline and acceptance specification " GB50369-2006, these long-distance transport pipes, after pressure testing finishes, need carry out the construction of wiper pigging simultaneously.Because the method for chemical degreasing is efficiently simple in degreasing operation, so need to use the method for chemical degreasing and physics wiper pigging in the pigging project of above-mentioned particular/special requirement simultaneously, be published in " Petroleum Engineering Construction " the 3rd phase in 1997 " application study in water injection pipeline cleans of PIG mechanical cleaning and chemical cleaning technique ", author Zhang Jincheng, Zhang Xianjun, Liu Suping, it in this paper, is the three-step approach that adopts PIG mechanical cleaning one chemical tendering liquid to clean a PIG mechanical cleaning, first at test pipe two ends, transmitter and receiver are housed respectively, adopt PIG mechanical cleaning method to carry out first step cleaning, then pull down transmitter and receiver, adopt the chemical tendering liquid of second step to clean, after end, reinstall again the mechanical cleaning method of PIG for the second time that transmitter and receiver carry out the 3rd step, finally also need to pull down transmitter and receiver, whole will mechanical cleaning and the chemical tendering stack cleaning process of cleaning in need installing/dismounting transmitter and receiver repeatedly, not only step bothers lost labor and time greatly, delay project progress.
