Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be described in detail the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to the scope of protection of the invention.
Shown in ginseng Fig. 1 to Fig. 4, gas product cooler, comprise housing 1, and be arranged at front header 2 and the rear header 3 at housing two ends, housing 1 limits a shell side space 11, the end of housing 1 both sides is respectively arranged with front tube sheet 4 and back tube sheet 5, heat exchanger tube 6 is fixed with between front tube sheet 4 and back tube sheet 5, front header 2 limits a tube side space 21 be communicated with heat exchanger tube 6, the wear-resisting distribution plate 7 of the erosion control be oppositely arranged with front tube sheet 4 is provided with in front header 2, the wear-resisting distribution plate of erosion control 7 offers multiple installing hole 71, one end of heat exchanger tube 6 to extend in tube side space 21 and fixes with installing hole 71.
In this technical scheme, the setting of the wear-resisting distribution metallic plate of erosion control greatly reduces the wearing and tearing of lining on catalyst powder foot couple front tube plate that gas product carries, a large amount of catalyst is carried in course of reaction when the apparatus is in operation due to the reactor of front end, the hardness of these catalyst is harder, just run often due to the wearing and tearing of catalyst normally, lining and tube head on the tube sheet of front end is caused to be worn, equipment is caused normally to run, this device thoroughly eliminates the wear problem of tube sheet and tube head, greatly improves the security of equipment.
Heat exchanger tube 6 comprises the sleeve pipe 61 and outer heat exchanger tube 62 that are set in together, the two ends of outer heat exchanger tube 62 are located on front tube sheet 4 and back tube sheet 5 respectively, one end of sleeve pipe 61 is fixed in the installing hole 71 of the wear-resisting distribution plate 7 of erosion control, and the other end is arranged in one end of outer heat exchanger tube 62.
In common reactor product cooler, if the gas product of high temperature is by during directly by heat exchanger tube, the gas product of high temperature can the welding point of direct contact heat-exchanging pipe and tube sheet, instability simultaneously owing to running, the temperature of gas product is fluctuated, fatigue damage is caused to the weld seam at this place, in order to address this problem, metal dispensing tube is set, isolation high-temperature gas contacts with the direct of pipe joint weld seam, revolutionize the weld seam stress between heat exchanger tube and tube sheet, extend the service life of equipment, save resource.
Front header 2 has the entrance 22 of a taper, and this entrance 22 increases gradually along airintake direction opening.
The lining pre-buried checked spun antung antifriction metal (AFM) lining 8 of front header 2.The lining pre-buried checked spun antung antifriction metal (AFM) lining 8 of rear header 3.
Because the pellet hardness of catalyst is large, too large to the wearing and tearing of lining, due to the wearing and tearing being also difficult to this catalyst of opposing of wearing layer, complete being also difficult to of Lining wear is found, once find that housing is worn, in order to prevent destroying, checked spun antung metal being set and being embedded in below lining, greatly improving the wearability of equipment.
Shell side space 11 is separated into strengthening cooling chamber 111 and general cooling chamber 112 by a point chamber plate 9, strengthening cooling chamber 111 is near described front tube sheet 4 one end, the top of strengthening cooling chamber 111 and general cooling chamber 112 is respectively equipped with steam (vapor) outlet 113, be provided with at least one piece of rigidity deflection plate 114 in general cooling chamber 112, rigidity deflection plate 114 forms the fluid passage set in shell side space together with the inwall of housing 1; Strengthening cooling chamber adopts low temperature water-cooled to cool fast.
At shell side near high temperature tube sheet, scope determines this section of length strengthening separately cooling chamber depending on the diameter of equipment, adopt monoblock gripper shoe every live opposite side fluid heat exchange evaporating area, the fluid of one low temperature is introduced separately between high temperature tube sheet and gripper shoe, forced convertion is carried out between high temperature tube sheet and gripper shoe, quick cooling high temperature tube sheet above, benefit is the heat transfer temperature that improve high-temperature product gas and low-temperature material, enhance heat transfer, low-temperature material upwards washes away high temperature tube sheet and high temperature tube bank, produce steam to go out from above, whereabouts drum is separated, this has been apt to the stressed of high temperature tube sheet to this device greatly, the temperature reducing tube sheet improves the allowable stress of material, improve the security of equipment.
Further, the width range 600mm-1900mm of independent strengthening cooling chamber, import low temperature caliber 50-500mm, outlet caliber 80-600mm, gripper shoe separate space plate thickness 6-35 millimeter, low-temperature material import is in lower end, outlet is at top, specification all size between 25mm-89mm of heat exchanger tube, containing pipe made in Great Britain, material is, 20g, 20, 15CrMo, SA-179, SA-213T12, cylinder material Q345R, 15CrMOR.SA516-70, SA387G12 etc., reactor product cooler diameter range 600mm-3200mm, heat exchanger tube length 3m, 3.5m, 4.0m, 4.5m, 5m, 5.5m, 6m, 6.5m, 7m, 7.5m, 8m, 8.5m, 9m, 9.5m, 10m.10.5m, 11m, 12m, 13m, 14m, 15m, 18m.Heat exchanger tube spacing is 1.3-3.5 times of heat exchanger tube external diameter.
In this technical scheme, the design of strengthening cooling chamber, greatly change the Temperature Distribution of high temperature tube sheet, change a shell side flowage structure of conventional cooler, reduce the temperature of high temperature tube sheet, improve the allowable stress value of tube sheet, improve the safety coefficient of tube sheet, when high temperature gas flow is through front end tube sheet, one cold water independent of strengthening cooling chamber can be lowered the temperature to this tube sheet fast, avoid high temperature cracking and the fatigue damage of tube sheet, greatly reduce the probability of tube head weld cracking, improve the security performance of equipment, enhance the heat exchange of temperature end simultaneously, improve the efficiency of equipment.
In the present embodiment; tube side medium enters front header from tube side import; then through erosion control antifriction metal (AFM) baffle plate; metal sleeve enters heat exchanger tube; come in first to clash into erosion control antifriction metal (AFM) distribution plate after bobbin carriage at the gas product of high temperature; separate some catalyst; protect the welding point of heat exchanger tube and tube sheet; substantially increase the impact capacity of tube head; the front end wear-resisting layer covering of tube sheet simultaneously; this wearing layer also possesses heat insulation effect, greatly reduces the weld seam temperature of heat exchanger tube and tube sheet, improves the safety coefficient of tube head.Shell side medium enters general cooling chamber from strengthening cooling chamber, carry out heat-shift with medium in the pipe of temperature end after coming in, particularly take away the heat on tube sheet in a large number, reduce the temperature of tube sheet, improve the metal allowable stress of tube sheet inside, improve the safety coefficient of equipment, one enters from traditional cooling system, enters high-temperature medium that is rear and tube side and carries out heat exchange, produce steam, go out from the outlet of shell side upper end, enter the heating system of engineering, supply technique uses.Front header and tube sheet are covered with the lining of pre-buried checked spun antung antifriction metal (AFM) after also having rear header, greatly reduce the wearing and tearing of catalyst, and the tube head that housing and temperature end often occur traditional cooler is worn leakage phenomenon, causes huge loss to normal driving.
