Description

A kind of novel kettle type reboiler

Technical field

The utility model is related to Fractionator Bottom material is used in oil, petrochemical industry, chemical industry, rubber, metallurgy industry process units A kind of process equipment of heating, and in particular to novel kettle type reboiler.

Background technology

Mixed material carries out component in fractionating column in the industry productions device such as oil, petrochemical industry, chemical industry, rubber, metallurgy It usually needs to heat materials at bottom of tower the requirement that could meet separation accuracy in separation process, materials at bottom of tower mode of heating point To directly heat and indirectly heat, the mode of directly heating is divided into stripped vapor heating or electrical heating, and both mode of heatings by Dielectric property and thermal load conditions are limited, and are only applied under fewer operating mode, and most widely used mode of heating surely belongs to Indirectly heat, indirect heating manner are mainly that materials at bottom of tower is released by heating equipment tube bank heat exchange to obtain external heat source Heat, most common heating equipment has heating furnace, reboiler in indirect heating manner, and heating furnace will suitable for materials at bottom of tower temperature Seek higher occasion, for column bottom temperature under oil, petrochemical industry, chemical industry majority operating mode be not required for it is very high in the case of, then More use reboiler.

Reboiler is also reboiler, be during the industry productions such as oil, petrochemical industry, chemical industry, rubber, metallurgy it is most commonly seen, A kind of Fractionator Bottom heating equipment the most commonly used is a kind of indispensable particularly in oil, petrochemical industry, chemical industry Important technological equipment, it is exchanged heat usually using steam or other high-temperature mediums as heat source by tube bank, the material for carrying out bottom of towe It is returned in tower after heating vaporizes, so as to which materials at bottom of tower be made to obtain the heat needed for fine separation.

Common reboiler has, kettle type reboiler（With reference to figure 1）, thermosiphon reboiler（With reference to figure 2）, pump forced circulation Formula reboiler（With reference to figure 3）, thermosiphon reboiler can be divided into horizontal thermosiphon reboiler and vertical thermosiphon weight again Device is boiled, pump forced cyclic type reboiler is identical with thermosiphon reboiler pattern pattern, and tower is only increased outside reboiler The forced circulation conveying function of substrate material, kettle type reboiler only have a kind of horizontal form.

The function of three kinds of reboilers is identical, and effect is all heating materials at bottom of tower, but applicable elements are then different.

Pumping forced cyclic type reboiler applicable elements is：When materials at bottom of tower viscosity is very high, or it is heated for a long time easily decompose or Malleable product coloration should select pump forced cyclic type reboiler when physical characteristics or easy fouling.

Thermosiphon reboiler has that tower product surge volume is big, operating flexibility is big, flow rate high stability, is not easy to draw The advantages that playing the fluctuation of downstream process equipment manipulation, but there is also bottom of towe space requirement is big, installation height difference requirement is big, rate of gasification It is low, material import and export temperature is slightly higher, less than one piece theoretical plate, liquid phase circulation amount are big, heat-exchanging tube bundle washes away that strong, vibration is big, pipe Easily it is thinned that perforation, service life is short, the later stage replaces that tube bank probability is high, the larger pipe arrangement of caliber is difficult, total investment expenses are more The shortcomings of.

Existing kettle type reboiler have bottom of towe space can reduce, install height difference require it is small, rate of gasification is high, operating flexibility Greatly, material import and export temperature is low, is equivalent to one block of theoretical tray, liquid phase circulation amount is small, heat-exchanging tube bundle wash away it is weak, with small vibration, no Easily thinned perforation, service life length, later stage replacement probability is low, caliber smaller conduit arrangement is easy, total investment expenses relatively province etc. is excellent Point, but tower product surge volume is small, flow rate stability is poor there is also going out, and easily causes lacking for downstream process equipment operation fluctuation Point.

Thermosiphon reboiler is using most common reboiler with kettle type reboiler, and the two applicable elements are essentially identical, It only has any different due to process conditions or different site layout project condition, it is tighter that vertical thermosiphon reboiler is usually used in project land used The project opened, in most cases using horizontal thermo-syphon reboiler.

Application reference number is 201220730065.8, and the applying date is the utility model of 2012-12-26《A kind of vibrationproof autoclave Reboiler》, application No. is 201621321302.X, the applying date is the utility model of 2016-12-05《A kind of kettle type reboiler》, There are the above problems.

On engineer application, existing kettle type reboiler is due to by equipment itself heat-exchanging tube bundle length, device frame planar junction The limitation of structure size so that the liquid storage volume of kettle type reboiler can not be designed sufficiently large, limit kettle type reboiler in large size Design application in engineering project so that the advantage of kettle type reboiler can not be applied performance, if it is possible to solve existing kettle The defects of formula reboiler fluid cushion volume is small, then kettle type reboiler is then than horizontal thermosiphon reboiler with more using excellent Gesture, this is also the crucial the very crux that current kettle type reboiler cannot be widely applied.

Utility model content

The purpose of this utility model is that solve the problems, such as that existing kettle type reboiler fluid storage space is insufficient, provides one The novel kettle type reboiler of kind, based on existing kettle type reboiler principle, by sleeved embedded structure pattern, kettle is placed in by original The storage space of formula reboiler tail end is changed to kettle type reboiler closure periphery, and an entirety is combined by the montage in structure Equipment increases liquid storage space, and novel kettle type reboiler craft science is compact-sized, and manufacture is feasible, easy to use, especially suitable Application may be selected in the operation item of thermosiphon reboiler or kettle type reboiler for that can use.
