Abstract

The invention relates to apparatus used in the chemical and petrochemical industries as well as other branches of industry for working with aggressive media under pressure, for example in the production of urea. The technical result achieved through the implementation of the invention is that of increasing the mechanical stability of the inner lining of the high pressure vessel and providing for the timely detection of penetrative defects in the weld seams of the lining. A high pressure vessel is proposed which comprises a main housing with through check holes and an inner lining made from sheets of corrosion-resistant material joined together by weld seams which have underplates disposed therebeneath. Each underplate is situated in a slot with gaps between the edges of the plate and the walls of the slot, while the slots themselves are located in the lining sheets on the side thereof that faces the vessel housing. The edges of the slot and plate which face the vessel housing may be beveled.

Description

СОСУД ВЫСОКОГО ДАВЛЕНИЯ  HIGH PRESSURE VESSEL
Область техники  Technical field
Изобретение относится к аппаратам, используемым в химической, нефтехимической и других отраслях промышленности для работы с агрессивными средами под давлением, например, в производстве карбамида.  The invention relates to apparatuses used in the chemical, petrochemical and other industries for working with aggressive environments under pressure, for example, in the production of urea.
Предшествующий уровень техники  State of the art
Известен сосуд высокого давления, содержащий несущий корпус и внутреннюю футеровку, выполненную из листов коррозионностойкого материала, соединенных сварным швом внахлестку (US 2172819, В23К 9/007).  Known high pressure vessel containing a bearing housing and an inner lining made of sheets of corrosion-resistant material connected by a weld lap (US 2172819, V23K 9/007).
Известен сосуд высокого давления, содержащий несущий корпус и внутреннюю футеровку, выполненную из листов коррозионностойкого материала, соединенных сварными швами, под которыми размещены подложки, выполненные из двух клиновых элементов, закрепленных на листах коррозионностойкого материала параллельно их кромкам на расстоянии от последних с образованием замкнутой кольцевой полости (SU 1058592, ВО 1J 19/02).  Known high pressure vessel containing a bearing body and an inner lining made of sheets of corrosion-resistant material connected by welds, under which are placed substrates made of two wedge elements, mounted on sheets of corrosion-resistant material parallel to their edges at a distance from the latter with the formation of a closed annular cavity (SU 1058592, BO 1J 19/02).
Общими недостатками данных конструкций являются повышенная возможность гофрообразования из-за уменьшения устойчивости обечайки футеровки вследствие изначально задаваемого отклонения формы от цилиндричности и отсутствие системы контроля герметичности сварных швов футеровки.  Common disadvantages of these designs are the increased possibility of corrugation due to a decrease in the stability of the shell of the lining due to the initially set deviation of the mold from cylindricality and the absence of a system for monitoring the tightness of the lining welds.
Наиболее близким к предложенному является сосуд высокого давления, содержащий несущий корпус со сквозными контрольными отверстиями и внутреннюю футеровку, выполненную из листов коррозионностойкого материала, соединенных сварными швами, под которыми размещены подкладные пластины, расположенные в пазах корпуса с зазорами между кромками пластины и стенками паза (Румянцев О.В. Оборудование цехов синтеза высокого давления в азотной промышленности, М.: Химия, 1970, с. 235).  Closest to the proposed one is a pressure vessel containing a bearing body with through-hole control holes and an inner lining made of sheets of corrosion-resistant material connected by welds, under which are placed backing plates located in the grooves of the body with gaps between the edges of the plate and the walls of the groove (Rumyantsev OV Equipment of high pressure synthesis workshops in the nitrogen industry, Moscow: Chemistry, 1970, p. 235).
К недостаткам данной конструкции относятся ослабление несущей способности корпуса сосуда пазами, являющимися концентраторами напряжений и возможность образования гофр на футеровке в случае недостаточной величины осевого зазора между подкладной полосой и стенкой паза корпуса для компенсации разности линейного расширения материалов корпуса и футеровки. Также при сдвиге футеровки относительно корпуса подкладные пластины могут перекрывать контрольные отверстия в корпусе сосуда, что может затруднить доступ к ним продукта в случае возникновения протечек в швах футеровки и не позволит предпринять своевременные меры по ремонту футеровки, что, в свою очередь, может привести к повреждению корпуса сосуда. The disadvantages of this design include the weakening of the carrying capacity of the vessel body by the grooves, which are stress concentrators, and the possibility of corrugation in the lining in case of insufficient axial clearance between the backing strip and the wall of the housing groove to compensate for the difference in the linear expansion of the body materials and the lining. Also, when the lining is shifted relative to the body, the backing plates can overlap the control holes in the vessel body, which may impede product access in case of leaks in the lining joints and will not allow timely measures to be taken to repair the lining, which, in turn, can lead to damage vessel body.
Раскрытие изобретения  Disclosure of invention
Задача, решаемая предлагаемым изобретением, заключается в совершенствовании конструкции сосуда высокого давления с внутренней футеровкой, обеспечивающей улучшение надежности работы аппарата.  The problem solved by the invention is to improve the design of the pressure vessel with an inner lining, which improves the reliability of the apparatus.
Техническим результатом, полученным при осуществлении изобретения, является повышение механической устойчивости внутренней футеровки сосуда высокого давления и обеспечение своевременного обнаружения сквозных поражений сварных швов футеровки.  The technical result obtained by carrying out the invention is to increase the mechanical stability of the inner lining of a pressure vessel and to ensure the timely detection of through lesions of the welds of the lining.
Для достижения указанного результата предлагается сосуд высокого давления, содержащий несущий корпус со сквозными контрольными отверстиями и внутреннюю футеровку, выполненную из листов коррозионностойкого материала, соединенных сварными швами, под которыми размещены подкладные пластины, расположенные в пазах с зазорами между кромками пластины и стенками паза, о тл и ч аю щи й ся те м , что пазы расположены в соединяемых листах футеровки со стороны, обращенной к корпусу сосуда.  To achieve this result, a high pressure vessel is proposed, comprising a supporting body with through inspection holes and an inner lining made of sheets of corrosion-resistant material connected by welds, under which there are backing plates located in grooves with gaps between the edges of the plate and the walls of the groove, about t and, moreover, the grooves are located in the joined sheets of the lining from the side facing the vessel body.
На кромках паза и пластины, обращенных к корпусу сосуда, могут быть сделаны скосы.  At the edges of the groove and plate facing the vessel body, bevels can be made.
Размещение пазов с подкладными пластинами в стенке футеровки позволяет футеровке свободно перемещаться вдоль корпуса сосуда при разогреве и охлаждении футеровки, а, следовательно, позволяет избежать гофрообразования. При выполнении футеровки по данному способу сохраняется цилиндричность обечайки футеровки, обеспечивающая ее устойчивость при воздействии продольных сжимающих усилий. В случае протечки через сварной шов футеровки, продукт попадает в каналы системы контроля герметичности футеровки, образованные зазорами между кромками пластины и стенками паза, и выводится через контрольное отверстие в корпусе сосуда в систему регистрации утечек, что позволяет принять своевременные меры по ремонту футеровки, исключающие поражение корпуса. С целью уменьшения возможного влияния местных неровностей корпуса на свободу перемещения футеровки относительно корпуса, возможно выполнение скосов кромок паза и пластины, обращенных к корпусу сосуда. The placement of grooves with backing plates in the wall of the lining allows the lining to move freely along the vessel body during heating and cooling of the lining, and, therefore, avoids corrugation. When performing the lining according to this method, the cylindricality of the shell of the lining is maintained, which ensures its stability under the influence of longitudinal compressive forces. In case of leakage through the lining weld, the product enters the lining tightness control system channels, formed by the gaps between the plate edges and the groove walls, and is discharged through the inspection hole in the vessel body to the leakage registration system, which allows timely measures to be taken to repair the lining, excluding damage to the body. In order to reduce the possible effect of local irregularities of the housing on the freedom of movement of the lining relative to the housing, it is possible to make bevels of the groove and plate edges facing the vessel body.
