Definitions
- 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.
- 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.
- 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.
- 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.
- a high pressure vessel 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.
- bevels can be made.
- 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.
- the cylindricality of the shell of the lining is maintained, which ensures its stability under the influence of longitudinal compressive forces.
- 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.
- FIG. 1 to 4 schematically depict the proposed lined pressure vessel.
- FIG. 1 shows a longitudinal section through a pressure vessel
- FIG. 2 node A of FIG. 1, which shows the junction of the lining sheets in the area of the test hole, in FIG. 3 - the node In FIG. 1, which shows the junction of the lining sheets in an area without a control hole.
- FIG. 4 shows the junction of the lining sheets with the beveling of the edges of the groove and plate facing the vessel body.
- the proposed pressure vessel comprises a supporting body 1 with through inspection holes 2 and an inner lining 3 made of sheets of corrosion-resistant material connected by welds 4, under which the underlay plates 5 are located in the grooves 6, with a gap 7 between the edge of the plate and a groove wall.
- the inner lining 3 moves freely along the vessel body 1.
- the product enters into the gaps 7, which function as channels of the system for monitoring the tightness of the lining, and is discharged through the control holes 2 in the vessel body into the leak detection system (not shown in Figs. 1-4).
- the invention can be used in the chemical, petrochemical and other industries in apparatus for working with aggressive environments under pressure, for example, in the production of urea.
