Detailed description of the invention
As shown in Figure 1-Figure 3, a kind of supporting construction of shell and tube reactor heat exchanger tube inner catalyst, comprise and assemble by spring-support plate handling instrument the spring-support plate 8 be placed in heat exchanger tube 10 lower end of shell and tube reactor, spring-support plate 8 is coaxial with heat exchanger tube 10, multiple circumferentially equally distributed resiliency supported pin 9 is connected with bottom spring-support plate 8, the machine-shaping of heat exchanger tube 10 lower end inner wall has a ring groove 11, resiliency supported pin 9 bottom spring-support plate 8 is supported in heat exchanger tube 10 inner groove 11, by spring-support plate 8 at heat exchanger tube 10 inner support catalyst granules 12.
If heat exchanger tube 10 diameter is D, the annular diameter that heat exchanger tube 10 inner groove 11 surrounds is D3, spring-support plate 8 diameter is D1, the round diameter that bottom spring-support plate 8, multiple resiliency supported pin 9 lower end surrounds is D2, spring-support plate 8 need be processed as its diameter D1 and be less than heat exchanger tube 10 diameter D, namely have annular gap between spring-support plate 8 and heat exchanger tube 10, the width of annular gap should be less than catalyst 12 grain diameter; Be designed to the round diameter D2 that resiliency supported pin 9 lower end surrounds to be greater than the annular diameter D3 that heat exchanger tube 10 inner groove surrounds simultaneously.
In spring-support plate 8, centrally axis direction arranges several through holes, and for medium circulation in heat exchanger tube 10, the diameter of through hole is less than the particle diameter of catalyst.
As Figure 4-Figure 7, spring-support plate handling instrument comprises straight-cylindrical urceolus 2, urceolus 2 top barrel is provided with back-up ring 4, and back-up ring 4 is fixed on urceolus 2 by holding screw 5, there is the breach 21 of multiple tracks channel shaped at nozzle edge, urceolus 2 top circumferentially even machine-shaping, in urceolus 2, coaxial rotation is provided with core bar 3, circular footstock 6 is installed in the nozzle of urceolus 2 top, footstock 6 upper end passes from urceolus 2 top nozzle, and footstock 6 upper end edge even circumferential is processed with several breach 21, footstock 6 lower end and core bar 3 top are threaded connection, urceolus 2 top, on footstock 6, breach quantity is identical with spring-support plate 8 bottom resilient feet 9 quantity, in the barrel of urceolus 2 lower end, also machine-shaping has the through hole 7 moved towards twist on urceolus 2 barrel, also include handle 1, be threaded connection on core bar 3 after the through hole 7 of handle 1 through spirality trend on urceolus 2 barrel,
During mounting spring gripper shoe, resiliency supported pin is blocked with the footstock breach of handling frock, by the ring groove position of spring-support plate jacking heat exchanger tube lower end, resiliency supported pin is flexible, shunk by the extruding of heat exchanger tube inwall when just having entered heat exchanger tube, when reaching heat exchanger tube ring groove position, resiliency supported pin opens automatically due to elasticity, is supported in heat exchanger tube annular groove firmly; After spring-support plate installs, catalyst loads from heat exchanger tube top, is supported, be full of whole heat exchanger tube by spring-support plate;
During dismounting spring-support plate, only block resiliency supported pin with the breach on handling frock urceolus, rotate urceolus, the round diameter size compression that the resiliency supported underfooting end of spring-support plate can be surrounded, can light pull-off spring gripper shoe to the internal diameter being less than heat exchanger tube.
In the utility model, footstock 6 upper end circumference is processed with several (quantity is with latch plate feet quantity) breach, in order to block spring-support plate, during mounting spring gripper shoe, according to the position of heat exchanger tube lower end pipe internal channel, the distance of back-up ring 4 to footstock 6 is transferred to required distance, spring-support plate jacking heat exchanger tube, promptly urceolus 2, pulls handle 1, handle 1 advances along the helicla flute on urceolus 2, can by the groove of spring-support plate jacking heat exchanger tube lower end.
Urceolus 2 upper end circumference is uniform is processed with several (quantity is with latch plate feet quantity) breach.During dismounting spring-support plate, only need to use urceolus 2, block the corresponding feet of spring-support plate with these breach of urceolus 2 upper end, rotate urceolus 2, can pull-off spring gripper shoe.
