Abstract

The utility model discloses a dissolution extension-type heat exchanger. Inner pipes (1) are fixed inside an outer pipe (2), the number of the inner pipes (1) is more than four and the inner pipes (1) are distributed on the circumference with an axis of the outer pipe (2) as a center. Compared with the prior art, by increasing the number of the inner pipes and changing the arrangement mode of the inner pipes, the aim of raising comprehensive heat transfer coefficient of equipment can be achieved.

Description

A kind of dissolving-out cannula formula heat exchanger
Technical field
The utility model relates to the inner tube in a kind of heat-exchange apparatus, particularly double pipe heat exchanger.
Background technology
Along with improving constantly of alumina producing technology, production capacity is also increasing year by year.Various device faces the maximization demand in succession.Stripping is as the core of process for making alumina, and the maximization of its equipment design is also quite concerned.By the calculating of complex heat transfer coefficient as can be known, under the equal conditions, the complex heat transfer coefficient of dissolving-out cannula is apparently higher than autoclave.Just be based on this reason, strengthening all recommend adoption double pipe heat exchangers of stripping.Three sleeve pipes of present industrial application and Quadruplet pipe be because the unit heating surface (area) (HS is less, causes that pipe range is long, tube side is more; And the quantity that increases the sleeve pipe inner tube namely can increasing device inlet amount, can well address this problem again.This is the thinking of dissolving-out cannula formula heat exchanger maximization design just.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of dissolving-out cannula formula heat exchanger is provided, and its complex heat transfer coefficient is improved, and guarantees best heat transfer effect.
Technical solutions of the utility model are: by increasing the inner tube quantity of double pipe heat exchanger, more than four, satisfy the requirement of equipment enlarging with this.Arranging of the inner tube of sleeve pipe adopted fork row mode as far as possible simultaneously, is distributed on the circumference centered by the outer axial tube line.By adjusting the arrangement mode of inner tube, improve the complex heat transfer coefficient of equipment.Particularly when the heat medium outside the inner tube is the steam class, need also to consider that inner tube pipe outer wall steam condensate drippage is on the impact of other inner tube pipe outer wall steam-condensation films.Avoid being attached to possibility that the condensation film of pipe outer wall thickens, to guarantee its complex heat transfer coefficient maximum as far as possible.
The utility model and conventional art compare: by increasing the quantity of inner tube, change simultaneously its arrangement mode, reached the purpose that improves the equipment complex heat transfer coefficient.
Description of drawings
Fig. 1~Fig. 2 is the schematic diagram that the five sets of tube exchangers inner tube is arranged;
Fig. 3~Fig. 5 is the schematic diagram that six double-tube heat exchanger inner tubes are arranged;
Fig. 6 is the schematic diagram that seven double-tube heat exchanger inner tubes are arranged.
The specific embodiment
Embodiment 1
Such as Fig. 1~Fig. 2, the distribution of five sleeve pipe inner tubes 1 comprises dual mode, and five inner tubes 1 among Fig. 1 are arranged in the outer tube 2 in mode uniform on the concentric circles.An inner tube 1 is placed in the middle among Fig. 2, and four inner tubes 1 are peripheral at this pipe, are arranged in the outer tube 2 in mode uniform on the concentric circles.Contrast two kinds of arrangement modes, except the fork of foundation thermal conduction study augmentation of heat transfer row formula cloth principle, when also having considered to be the steam class for heat medium, inner tube 1 pipe outer wall steam condensate drippage is on the impact of condensation film thickness.Although when heat medium is high-temperature molten salt, do not relate to steam condensate drippage to the impact of condensation film thickness, even if the dissolving-out process that heats with fused salt need to utilize the secondary vapour that decrease temperature and pressure after its stripping produces equally.Usually these secondary vapour are used for the preheating ore pulp, so the arrangement mode among Fig. 1 is better than the arrangement mode among Fig. 2.
Embodiment 2
Such as Fig. 3~Fig. 5, the distribution of six sleeve pipe inner tubes 1 comprises three kinds of modes, and the six roots of sensation inner tube 1 among Fig. 3 is evenly arranged on the circumference centered by outer tube 2 axis, and the inner tube 1 among Fig. 4 and Fig. 5 has one at the center, and all the other five are distributed on the circumference.Contrast three kinds of arrangement modes, except the fork of foundation thermal conduction study augmentation of heat transfer row formula cloth principle, when also having considered to be the steam class for heat medium, inner tube 1 pipe outer wall steam condensate drippage is on the impact of condensation film thickness.Although when heat medium is high-temperature molten salt, do not relate to steam condensate drippage to the impact of condensation film thickness, even if the dissolving-out process that heats with fused salt need to utilize the secondary vapour that decrease temperature and pressure after its stripping produces equally.Usually these secondary vapour are used for the preheating ore pulp, so the arrangement mode among Fig. 4 and Fig. 5 is better than the arrangement mode among Fig. 3.
Embodiment 3
Such as Fig. 6, the inner tube 1 of seven sleeve pipes has one at the center, and all the other six roots of sensation are distributed on the circumference centered by outer tube 2 axis.This arrangement mode is the optimal alignment of seven sleeve heat exchangers.
