Description
Technical field
The invention belongs to heat transmission equipment, particularly a kind of for the large temperature rise of Low Temperature Difference the pure reverse stream pipe shell heat exchanger of multipaths without heat exchange between phase-change liquid.
Background technology
The large temperature rise of Low Temperature Difference without the heat exchange between phase-change liquid be mainly used in space-heating system that the discrepancy in elevation is larger every pressing heat transmission equipment and plant drainage cooler, the temperature difference generally only have 5 DEG C～10 DEG C actual be more low better, and the pressure of equipment higher be generally that plate type heat exchanger can not bear at 2.5～4.5MPa, and must pure adverse current just can realize, currently used heat transmission equipment form is mainly traditional shell-and-tube, many cascaded structures of fixed tube-sheet exchanger meet temperature difference requirement or separate unit is realized under the low flow velocity of heat exchange extreme difference, this just need to sacrifice very large heat exchange area.Adopt the structure of the pure adverse current of separate unit multipaths, because shell-side multipaths is difficult to realize by traditional shell-and-tube heat exchanger structure.Those skilled in the art are devoted to design a kind of can solution all the time and realize the effective high-performance heat exchanger of the pure countercurrent flow of shell side multipaths for this reason, but at present only, not yet have new breakthrough
Summary of the invention
In order to solve the deficiency that still there is no the effective high-performance heat exchanger of the pure countercurrent flow of shell side multipaths, the object of this invention is to provide the pure reverse stream pipe shell heat exchanger of a kind of multipaths, the pure reverse stream pipe shell heat exchanger of this multipaths has not only been realized the pure counter-flow designs of monomer heat exchanger multipaths, make it have high temperature high voltage resistant, heat-transfer effect is good, running resistance is little, compact conformation, to tube bank without impact etc. feature.
The technical solution adopted for the present invention to solve the technical problems is: the pure reverse stream pipe shell heat exchanger of a kind of multipaths, comprise front-end pipe box, rear end header, shell side, it is characterized in that: shell side is made up of the outer water conservancy diversion entrance end of shell-side, front tube sheet, back tube sheet, pass partition, heat-exchanging tube bundle, rod baffle group, distinguish housing
The outer water conservancy diversion entrance end of described shell-side is made up of external flow guiding cylinder body and inner draft tube body that shell side import and shell side outlet are housed, external flow guiding cylinder front end and front tube sheet are welded to connect, and rear end and distinguish housing are welded to connect, and inner draft tube front end is vacant, rear end is connected to distinguish housing front end
Heat-exchanging tube bundle is through rod baffle group and front tube sheet, back tube sheet, and heat-exchanging tube bundle two ends are connected with front tube sheet, back tube sheet welding or expanded joint respectively, and centre is supported by rod baffle group;
Middle pass partition and front tube sheet and external flow guiding cylinder, inner draft tube, distinguish housing are welded to connect, middle pass partition central plate and back tube sheet are welded to connect, be provided with tube side import and export front header in be provided with the front end pass partition corresponding with middle pass partition, in rear header, be provided with the rear end pass partition corresponding with middle pass partition central plate.
The middle pass partition exporting near described shell side and external flow guiding cylinder, inner draft tube surround the outlet diversion cavity of semicircle annular, and the middle pass partition of close described shell side import and external flow guiding cylinder, inner draft tube surround the import diversion cavity of semicircle annular.
Described distinguish housing is at least 2 lobes, and composition circular cylinder body after welding with middle pass partition.
Described middle pass partition is parallel to each other, and flow process number is at least 2 journeys.
The invention has the beneficial effects as follows: owing to adopting the pure counter-flow designs of multipaths to there is good effect of heat exchange, can realize the heat exchange of Low Temperature Difference high temperature rise; Owing to adopting the traditional heat exchangers form of circular shell, there is high temperature high voltage resistant and repair and maintenance feature easily, be that plate type heat exchanger is not available; Because adopting deflection bar type supporting construction, shell-side tube bundle support makes it have the feature that good effect of heat exchange fluid resistance is little; Because shell-side is imported and exported the outer water conservancy diversion buffer structure of employing, the circulation area of not only having avoided fluid to increase import to restraining the impact of direct generation has reduced liquid entrance flow velocity greatly, and the end that fluid flows backward to tube bank is entered to tube bank makes to restrain heat exchange without dead band; Owing to adopting the exterior version distinguish of shell side housing distinguish to be no less than two lobes, make comparatively complicated shell side multipaths structure in the housing suit situation that cannot realize, the spiral-lock of the housing by distinguish comparatively simply realizes, manufacture and design thereby realize shell side multipaths, shell-side is divided into multipaths with middle pass partition by circular shell; Equipment simple in structure, easily manufactured, be a kind of energy-saving heat-exchange equipment efficiently.
