Description
Technical field
The invention belongs to chemical industry and technical field of petrochemical industry, and it is swollen with sliding tube sheet and inside that the invention proposes one kind
The vertical shell-and-tube heat exchanger of swollen section, especially suitable for heating low temperature process material using high temperature super heated steam, in particular for
In the dehydrogenation reaction technique of aromatic hydrocarbons.
Background technique
In chemical industry and petrochemical industry, heat exchanger using very extensive, be that indispensable common technique is set
It is standby, in daily life and it is seen everywhere.According to statistics, heat exchanger accounts for the 40% of equipment sum in oil refining and chemical plant installations
Left and right, investment account for the 30-45% of gross investment.Recently as the development of power-saving technology, high temperature, Low Temperature Thermal are carried out using heat exchanger
The recycling of energy brings significant economic benefit.Currently, maximum usage amount is shell-and-tube heat exchanger in heat exchange equipment.With
The development of petroleum industry and chemical industry, the shell-and-tube heat exchanger that various harsh conditions use is more and more, such as is refining oil
Be hydrocracked, kerosene hydrogenation, gasoline, diesel add hydrogen and lube oil hydrogenation, catalytic reforming, hydrofinishing etc., the second in chemical industry
Alkene cracking, ethylbenzene dehydrogenation, high-pressure and low-pressure polymerization, ammonia synthesis, natural gas conversion in chemical fertilizer etc., heat exchanger needs to bear pressure
Power is from vacuum to 35MPa, temperature is up to 700 ~ 900 DEG C of harsh use environment.Since the 21th century, with device enlargement
High speed development, the use of large heat exchanger is more and more wide, more and more frequently, technical difficulty is more and more big, reliability of equipment
It is required that higher and higher.How to ensure heat transfer effect, improve the thermal efficiency, improves the reliability of equipment, have become highly important
Research topic, the various large heat exchanger technologies applied under the conditions of special process emerge one after another, too numerous to enumerate.
Most common two kinds of heat exchangers are fixed tube-sheet exchanger and movable tube sheets heat exchanger in shell-and-tube heat exchanger.Such as
Shown in attached drawing 1 and attached drawing 2, since heat exchanger tube pass and shell-side fluid exchange heat, temperature difference is certainly existed, when temperature difference arrives greatly
It, just must be using the engineering measure for eliminating expansion when the temperature stress that can be born more than material.Such as attached drawing 1, in fixed tube sheet
In heat exchanger, since both ends tube sheet is fixed, so expansion joint can only be arranged on shell, when elongation or contracting occur for tube bank
In short-term, it can be compensated by the elongation and shortening of expansion joint, not leaked between tube side and shell side to ensure, guarantee base
This heat transfer effect.If attached drawing 2 does not have expansion joint in movable tube sheets heat exchanger on shell, so tube side one end uses fixing pipe
Plate, the other end (are raised the nose above water to breathe) using sliding tube sheet, and tube bank freely can extend and shorten in shell, but this measure solves
It is the problem of expansion, inevitable by bringing another question, i.e., the Fluid Sealing problem between tube side and shell side.In order to solve
This problem, common method are that, due to using sealing structure, necessarily have leakage, so only using packing box seal structure
It can guarantee that the amount of leakage controls within the scope of acceptable, such as no more than the 5% of total flow.
In these two types of heat exchangers, fixed tube-sheet exchanger and movable tube sheets heat exchanger, usually by dress pattern, there are two types of horizontal
Or it is vertical.Chinese patent CN200820151384.7 discloses a kind of horizontal shell with guided bearing and packing box seal
Formula heat exchanger;Chinese patent CN200710043304.6 discloses a kind of horizontal shell with guided bearing and inner expansion joint
Formula heat exchanger, it is intended to solve above as tube side, shell side thermal stress and expansion issues as caused by the temperature difference.In vertical floating head type
In heat exchanger, stuffing-box is able to maintain good stress, there is certain circumferential uniformity, can guarantee the amount control of leakage
Within the scope of acceptable.When case swells section is arranged in vertical heat exchanger, cutting when the unbearable earthquake of expansion joint occurs
Shear force, and when being designed to bear earthquake shearing power, and the expansion almost lost due to rigidity and intensity.But
Enlargement is that expansion joint is arranged on pressure hull, and reliability and device security are difficult to be guaranteed.
Summary of the invention
In order to overcome drawbacks described above, it is an object of the invention to propose a kind of novel vertical shell-and-tube heat exchanger, lead to
Setting built-in heat exchanger structure is crossed, the leakage of fluid between tube side and shell side is avoided, while guaranteeing that the tube side of heat exchanger can be with
