Abstract
The utility model belongs to the expansion joint compensation technical field and provides a straight pipe pressure-balancing type expansion joint for a gasoline adsorption and desulfurization device. The expansion joint is mainly composed of an inlet flange (1), a pull rod (2), a guide cylinder (3), a working corrugated pipe (5), a balancing corrugated pipe (9), a middle pipe (7) and an outlet plate (12), wherein the working corrugated pipe (5) and the balancing corrugated pipe (9) are connected by the middle pipe (7). The straight pipe pressure-balancing type expansion joint is characterized in that a guide cylinder positioning slot is arranged on the inlet flange (1) and the middle pipe (7), one end of the guide cylinder (3) is positioned in the positioning slot, and the other end of the guide cylinder (3) is in a staircase-shaped structure; the middle pipe (7) and a middle annular plate (8) are in the structure formed by integrally forming forgings; and the end part of the pull rod (2) is provided with a spherical conical-surface gasket (13). The straight pipe pressure-balancing type expansion joint ensures the strength of the guide cylinder and the flowing smoothness of mediums, reduces the abrasion of high-speed flowing adsorbent particles for the guide cylinder and prolongs the service life of the expansion joint.
Description
Technical field
The utility model belongs to expansion joint compensation technique field, relates generally to a kind of gasoline absorbing desulfurization device straight pipe pressure-equalizing type expansion joint.
Background technique
S-zorb catalytic gasoline desulfurizer comprises that mainly charging and desulphurization reaction, adsorbent reactivation, sorbent circulation and product stablize four parts, is used to produce low-cost sweet gasoline.This device is based on the suction-operated principle, by adopting fluidized-bed reactor, uses special sorbent to remove sulphur in the raw material, thereby reaches the purpose of gasoline being carried out desulfurization.
The operating temperature of S-zorb catalytic gasoline desulfurization pipeline is 470 ℃, working pressure is up to 4.26MPa, interior media is hydrogen and the higher absorbent particles of flow velocity, needs to adopt three cover straight pipe pressure-equalizing type expansion joints to be used in the pipeline and compensates the displacements such as thermal walking, equipment foundation settlement and pipeline installation deviation that piping produces.
This device adopts original straight pipe pressure-equalizing type structure, and life cycle is very short, has only about half a year, and main cause is that the guide shell structural design of protection bellows is unreasonable.Its guide shell is conventional turnup structure, and stressed is a cantilever beam structure, and guide shell can not be obtained too thick.And flowing of flange section block media, because medium is swiftly flowing absorbent particles, swiftly flowing particle constantly washes away the flange place, guide shell is thinner, and very fast flange place is worn through, and medium directly touches bellows, cause bellows wearing and tearing perforation, expansion joint was lost efficacy.In addition because piping pressure is higher, expansion joint be can absorption pressure thrust the restricted type structure, the gross distortion of stress members also can cause the inefficacy of expansion joint.
Summary of the invention
The purpose of this utility model is to propose a kind of gasoline absorbing desulfurization device straight pipe pressure-equalizing type expansion joint.
The utility model is finished the technological scheme that its invention task taked:
A kind of gasoline absorbing desulfurization device mainly is made of inlet flange, pull bar, guide shell, work bellows, balance bellows, intervalve and exit plate with straight pipe pressure-equalizing type expansion joint; Described work bellows is connected by intervalve with the balance bellows, and described inlet flange and intervalve are provided with the guide shell locating slot, and an end of guide shell is positioned at locating slot, and the other end of guide shell is a step structure; Described intervalve, middle ring flat-plate are the whole machine shaping structure of forging.
Described exit plate is the plate with two arc surfaces and two straight flanges.
The gasoline absorbing desulfurization device that the utility model proposes straight pipe pressure-equalizing type expansion joint; three guide shell inwalls and inner-walls of duct are evened up; guaranteed the unobstructed property of guide shell intensity and media flow; of the wearing and tearing of swiftly flowing absorbent particles have been reduced to guide shell; effectively protect bellows, improved expansion joint working life.The guide shell right-hand member is a step structure, in the time of can avoiding the displacement of bellows compensate for lateral, and guide shell and the interference of holding inner tube wall.Intervalve and outer pipe have reduced welding capacity after adopting the forging structure, have avoided the welding deformation of structural member, have strengthened the bearing capacity of structural member, have improved the stressed of structural member.Tie rod end is provided with the ball taper faced washer, has guaranteed that expansion joint can better absorb lateral displacement.
