Description
Technical field
The present invention relates to heat abstractor technical field, be specially tubular heat exchanger.
Background technology
Tubular heat exchanger comprises housing, and housing both sides are provided with tube sheet and housing and are positioned at tube sheet outside and pass through end socketSealing, is provided with in housing and the tubulation of housing shaft line parallel, and tubulation two end supports is on tube sheet, and housing two ends have tube side and enterMouth, shell side outlet and tube side outlet, shell side entrance. The tube side distance of existing tubular heat exchanger equates with shell side distance, byBe subject to the restriction of installing space size in the axial length of housing, unsuitable long, shell side distance is shorter, directly causes shell and tube to changeThe tube side distance of hot device is short, heat exchanger time is short, heat transfer effect is poor.
Summary of the invention
The invention provides tubular heat exchanger, it can have longer tube side distance in the situation that shell side distance is shorterFrom, increase heat exchanger time, strengthen heat transfer effect.
Tubular heat exchanger, its technical scheme is such, comprises housing, described housing shaft is to both sides end face from inside to outsideTube sheet, end socket are installed successively, and the inner chamber of described housing is evenly placed with the tubulation with described housing shaft line parallel, described tubulationTwo end supports is in described tube sheet, and the corresponding described tubulation of described tube sheet installation site has the through hole with described end socket UNICOM, closeDescribed housing two ends, described housing is respectively equipped with shell side entrance and shell side outlet, it is characterized in that: also comprise longitudinal baffle, lengthFootpath lateral partitions and minor axis lateral partitions, the interior horizontally disposed length that has of cavity between end socket and the corresponding tube sheet of described housing one sideFootpath lateral partitions, cavity is divided into upper and lower two horizontal cavitys independently, the end socket of described housing opposite side and corresponding tube sheet by itBetween cavity in be longitudinally furnished with longitudinal baffle, this cavity is divided into two independently longitudinal cavitys by it, described in one of themLongitudinally horizontally disposedly in cavity there is minor axis lateral partitions, this longitudinal cavity is separated into and independently goes up local cavity, lower local chamberBody, described local cavity, lower local cavity respectively correspondence are provided with tube side entrance, tube side outlet.
It is further characterized in that:
Cavity interior horizontally disposed have major diameter lateral partitions, described length between end socket and the corresponding tube sheet of described housing one sideFootpath lateral partitions is specially N piece, natural number that wherein N is >=2, and it is individual upper and lower independently horizontal separately that it is divided into cavity (N+1)Cavity;
Described two independently longitudinally interval is horizontally disposed successively in cavity N piece minor axis lateral partitions, a described N piece minor axisLateral partitions by described two independently longitudinally cavity be separated into (N+2) individual local cavity and lower local cavity, institute of independently going upState minor axis lateral partitions and described major diameter lateral partitions corresponding, also in the same plane one by one;
Described shell side entrance and described tube side entrance are positioned at described housing the same side;
The radially both sides of the inner chamber of described housing, there are several deflection plates along the axial direction interlaced arrangement of described housing;
Described housing downside, close described tube side exit are provided with discharge outlet.
Adopt after the present invention, its beneficial effect is: longitudinal baffle, major diameter lateral partitions and minor axis lateral partitions have and changeThe effect of fluid direction, tube side inner fluid is under the guide functions of minor axis lateral partitions, longitudinal baffle and major diameter lateral partitionsSuccessively through tubulation repeatedly, extend the distance of tube side, increased heat exchanger time, strengthened heat transfer effect; Meanwhile, deflection plateSetting can extend the mobile flow process of shell-side fluid, further increased the time of heat exchange, strengthened heat transfer effect.
