(54) СПОСОБ ОЧИСТКИ ВНУТРЕННИХ ПОВЕРХНОСТЕЙ ПОЛЫХ ИЗДЕЛИЙ(54) METHOD FOR CLEANING INTERNAL SURFACES OF COMPLETE PRODUCTS
1one
Изобретение относитс к способам очистки внутренних поверхностей полых изделий, например , емкостей, трубопроводов от загр знений нроизводственного и эксплуатационного характера и может быть использовано в машиностроении и других отрасл х народного хоз йства.The invention relates to methods for cleaning the inner surfaces of hollow articles, for example, containers, pipelines from industrial and operational pollution, and can be used in mechanical engineering and other public goods.
Известны способы промывки полых изделий от загр знений путем введени в ноток моющей жидкости наполнител , например, шарообразных гранул полиэтилена с удельным весом менее единицы 1, или рабочего тела в виде цепи из неискрового материала 2 или алюминиевых опилок 3, или водорастворимого гликолевого эфира 4, или бой форфора или подобных абразивных материалов, металлическа дробь, опилки 5, или гранулы микропористого губчатого материала размером не более 3 мм 6, или неорганические твердые веш,ества с частицами определенной формы 7.Methods are known for washing hollow articles from contamination by introducing into the notes of washing liquid a filler, for example, spherical polyethylene pellets with a specific weight of less than 1, or a working medium in the form of a chain of non-sparkling material 2 or aluminum sawdust 3, or water-soluble glycol ether 4, or Combating porphyry or similar abrasive materials, metallic shot, sawdust 5, or granules of microporous spongy material with a size of not more than 3 mm 6, or inorganic solid particles with particles of a certain shape 7.
Известен также способ промывки, прин тый за прототип, в котором по водопроводным трубам пропускают массу губчатых элементов из синтетической смолы с помощью воды 8.There is also known a washing method, adopted as a prototype, in which a mass of synthetic resin cancellous elements is passed through water pipes using water 8.
Недостатки известных способов - низка эффективность промывки внутренней поверхности изделий (полости), а главное - невозможность полного удалени наполнител изThe disadvantages of the known methods are low efficiency of washing the inner surface of the products (cavity), and most importantly, the impossibility of completely removing the filler from
промываемого издели (особенно со сложной внутренней конфигурацией) после процесса промывки.washed product (especially with a complex internal configuration) after the washing process.
Перечисленные наполнители интенсифицируют отрыв загр знений, но процесс удалени их из полости весьма сложен.These fillers intensify the separation of contaminants, but the process of removing them from the cavity is very complicated.
Цель изобретени - повышение эффективности промывки и обеспечение возможности полного здалени остатков наполнител изThe purpose of the invention is to increase the efficiency of washing and to ensure the possibility of complete discharge of the residue of the filler from
промываемого издели .washed product.
Достигаетс цель тем, что в качестве наполнител используют гранулы легкоиспар емого вещества, например, «сухого льда. В результате перемещени потока гранул наполнител внутренн поверхность изделий очищаетс без механических поврелодений промываемого издели . Частицы «сухого льда и образующийс при его испарении углекислый газ разрущают ламинарный подслой у стенок промываемого издели , тем самым интенсифициру процесс промывки и повышени ее качества. Благодар образованию при испарении «сухого льда углекислого газа не требуетс дополнительного подвода газа в моющий поток дл интенсификации промывки . «Сухой лед в процессе промывки полностью испар етс и удал етс из промываемой системы. Пример. В поток очищенной жидкостиThis is achieved by using granules of highly evaporated material, for example, dry ice, as a filler. As a result of the flow of filler granules, the inner surface of the products is cleaned without mechanical damage to the product being washed. The particles of dry ice and carbon dioxide formed during its evaporation destroy the laminar sublayer against the walls of the product being washed, thereby intensifying the washing process and improving its quality. Due to the formation of carbon dioxide during the evaporation of dry ice, no additional gas supply to the washing stream is required to intensify the washing. "Dry ice during the washing process is completely evaporated and removed from the flushing system. Example. Into the stream of purified liquid
ввод т гранулы «сухого льда, и полученна dry ice granules are introduced and the resulting
смесь подаетс в промываемую систему, например трубопровод. При выходе из промываемой системы от жидкости отдел етс газ и остатки «сухого льда, и жидкость очищаетс от загр знений.the mixture is fed to a flush system, e.g. When leaving the flushing system, gas and residues of dry ice are separated from the liquid, and the liquid is cleared of contaminants.
Очищенна жидкость снова поступает после добавлеии «сухого льда в промываемую систему. По окончании промывки производитс продувка системы газом, в результате которой испар ютс остатки «сухого льда.After the addition of dry ice to the flushing system, the purified liquid is again fed. At the end of the flushing process, the system is purged with gas, resulting in evaporation of "dry ice" residues.
