The utility model relates to a production device for petrochemical engineering, particularly to a hexane reboiler for an HEPD device. The hexane reboiler comprises tube pass cylinders, glands, a hexane outlet, a mother liquor inlet, a mother liquor outlet, a hexane inlet connecting tube, a hexane inlet flange, a tube bundle, tube plates, a shell pass cylinder, baffle plates and tube spacers, wherein the upper end of the shell pass cylinder is fixedly connected with the upper tube pass cylinder and the upper gland, the lower end of the shell pass cylinder is fixedly connected with the lower tube pass cylinder and the lower gland, the hexane outlet is formed in the upper gland, and the hexane inlet connecting tube and the hexane inlet flange are arranged on the lower gland; the tube plates are arranged at upper and lower ends of the shell pass cylinder, more than one tube spacer is fixed on the tube plates, more than one baffle plate is fixed on the tube spacers, and the tube bundle penetrates the tube plates and the baffle plates perpendicularly; and the mother liquor inlet and the mother liquor outlet are formed in upper and lower ends of the shell pass cylinder respectively. According to the hexane reboiler, the original connecting tube is changed into a flange type, filling is facilitated, the tube bundle can be pulled out conveniently, and cleaning and maintenance operations are simplified; the tube spacers are added, so that the baffle plates are more stable; and expansion joints are added, so that the additional stress caused by temperature differences is compensated.
Description
Technical field
The utility model relates to a kind of petrochemical production device, relates in particular to a kind of high density polyethylene device hexane reboiler.
Background technology
Reboiler is the class interchanger for the bottom product of vaporizing, the industries such as widespread use and oil, chemical industry, power, the energy.The hexane reboiler used in the high density polyethylene device production process is the heat heating hexane medium that utilizes mother liquor steam.When carrying out heat exchange, the temperature head between cylindrical shell and heat transfer tube can cause additional stress, easily causes the damage of cylindrical shell.Traditional hexane reboiler, filling material difficulty, change narrow space, can only adopt packing class filler.If this type of filler snap-in force is inadequate or inhomogeneous, be easy to produce mother liquor or hexane and reveal, cause fire or blast, very harmful.When maintenance and cleaning, traditional hexane reboiler need to slice off original flange, overhauls and clean the complete new flange of burn-oning again, and so not only the process complexity has also caused the waste of manpower and financial resources.In addition, existing reboiler appearance is all smooth, is difficult for installing, and affects work-ing life of device because of shell-side cylinder and the interbank inequality of being heated.
Summary of the invention
The utility model, for above-mentioned the deficiencies in the prior art, provides a kind of high density polyethylene device hexane reboiler.
High density polyethylene device hexane reboiler of the present utility model, comprise tube side cylindrical shell, end socket, hexane outlet, mother liquor entrance, mother liquor outlet, hexane inlet connection, hexane inlet flange, tube bank, tube sheet, shell-side cylinder, traverse baffle, spacing tube, be fixedly connected with the tube side cylindrical shell in the upper end of shell-side cylinder and be fixedly connected with time tube side cylindrical shell and lower cover with upper cover, lower end, be provided with on upper cover on hexane outlet, lower cover and be provided with hexane inlet connection and hexane inlet flange; The upper/lower terminal of shell-side cylinder is provided with tube sheet, has fixed more than one spacing tube on tube sheet, has fixed more than one traverse baffle on spacing tube, and tube bank is vertical through tube sheet and traverse baffle; Be provided with mother liquor entrance, lower end in the upper end of shell-side cylinder and be provided with the mother liquor outlet.
As further improvement of the utility model, described hexane inlet connection is connected with the hexane inlet flange, hexane inlet flange upper end, lower end configure in pairs, internal floating head is covered with male flange, the hexane inlet flange is connected, adopts double-screw bolt, nut to fix with male flange, the male flange place is provided with multilayer expanded ptfe annular filler, and lower flange compresses multilayer expanded ptfe annular filler and is connected with the upper flange bolt of outer floating end cover.
As further improvement of the utility model, described shell-side cylinder both sides are provided with hanging support.
As further improvement of the utility model, described shell-side cylinder is provided with expansion joint.
High density polyethylene device hexane reboiler of the present utility model, change original adapter into the male flange form, facilitate filler, be convenient to the extraction of tube bank, simplified and cleaned and maintenance, set up spacing tube, made traverse baffle more stable, increase expansion joint, compensated the additional stress that temperature head causes.
