Abstract
It is about an extension-type row tube heat exchanger. The utility model relating to operation equipment in chemical engineering unit, in particular to a novel row tube heat exchanger with extension configuration, is designed to offer an extension-type heat exchange tube bundle with an inner tube and an outer tube to substitute the conventional monotube type heat exchanger tube , to provide a circulatory flow in the pipe to substitute the cylindrical flow, and to reduce the depth of the stagnation strata to improve the heat transfer characteristic and increase the heat transmission coefficient and the heat transfer rate. The product includes: a tunnel body (7) with a low-temperature flow intake (10), a high-temperature flow vent (11), a heating steam intake (12) and a sweating vent (14), an up outer tube board (3) and an up inner tube board (4), fixed in the upside of the tunnel body (7), a lower outer tube board (5) and a lower inner tube board (6), fixed in the downside of the tunnel body (7), a bushing connected by an inner tube (1) and an outer tube (2), fixed on the tube board, two terminals of the tunnel body (7) connected with the shell cover. The product is designed to transfer heat between vapor and liquid two-phase or between the in-phase liquid.
Description
Technical field:
The utility model relates to a kind of chemical engineering unit operation equipment, more particularly, is the novel tubular heat exchanger with sleeve structure.
Background technology:
At present, the tubular heat exchanger of extensive use is formed tube bank by single heat exchanger tube, as shown in Figure 4, the two-phase fluid of its heat exchange flows respectively at pipe is inside and outside, conduct heat by tube wall, according to fluid in ducted flow behavior, central core flow velocity maximum, nearly tube wall detention layer is minimum, thermograde is bigger, and heat transfer coefficient is little, and rate of heat transfer is little, heat transfer temperature difference is big, wastes energy.
Summary of the invention:
The purpose of this utility model provides a kind of tubular heat exchanger with casing type heat exchanging pipe, casing type heat exchanging tube bank with pipe and outer tube in having replaces traditional single hose heat-exchanging tube bundle, make the plug flow of tube fluid become annular flow, make the detention layer attenuate, the bushing type tubular heat exchanger that heat-transfer character is improved.
Above-mentioned purpose realizes by following technical scheme:
The bushing type tubular heat exchanger, its composition comprises: the cylindrical shell with cryogen inlet, high temperature fluid outlet, heating steam inlet and condensate water outlet, described cylindrical shell internal upper part is fixed with upper exterior tube plate and last internal tube plate, the bottom is fixed with lower outer pipe plate and following internal tube plate in the described cylindrical shell, be fixed with a branch of sleeve pipe that is made of interior pipe and outer tube on the described tube sheet, described cylindrical shell two ends and end socket link.
Above-mentioned bushing type tubular heat exchanger, described interior pipe two ends are fixed on described upper exterior tube plate and the described lower outer pipe plate, and described going up on internal tube plate and the described internal tube plate down is fixed at described outer tube two ends.
Above-mentioned bushing type tubular heat exchanger, described sleeve pipe gather on tube sheet and arrange.
This technical scheme has following beneficial effect:
1. the utility model adopts the casing type heat exchanging pipe, makes tube fluid become annular flow by traditional plug flow, and heat-transfer character is improved, and heat transfer coefficient and speed improve, and heat-transfer effect improves, significantly energy savings.
2. the utility model adopts the casing type heat exchanging pipe, not only, flow regime make heat-transfer character improve because changing, and because the increase of interior pipe significantly increases heat transfer area, thereby the bigger raising of whole heat transfer coefficient and rate of heat transfer can make structural design compacter, efficient.
3. the utility model adopts the casing type heat exchanging pipe, and when heat transfer coefficient and rate of heat transfer improved, heat transfer temperature difference is also corresponding to be reduced, and makes the design dead space reduce, and the heat exchanger applications face enlarges, and is greatly favourable to operation of chemical industry heat exchange unit and production technology.
