Abstract
The utility model relates to a shell-and-tube heat exchanger. Two shells of the shell-and-tube heat exchanger are fixedly arranged side by side; a heat exchange pipe is arranged in each shell; the heat exchange pipes in the two shells are communicated; the two shells are communicated; the heat exchange pipe in each shell is integrally formed by two connecting parts and a heat exchange section; the connecting parts with smooth outer surfaces are formed at both ends of the corresponding heat exchange pipes; each heat exchange section is formed between the two corresponding connecting parts; and the outer surfaces of the heat exchange sections are full of threaded bulges. The shell-and-tube heat exchanger can improve the heat transfer efficiency, has a compact structure, not only saves the space, but also meets the heat exchange requirement.
Description
One, technical field:
The utility model relates to the chemical industry equipment heat exchanger that uses in the petroleum and petrochemical industry, what be specifically related to is a kind of shell-and-tube heat exchanger.
Two, background technology:
Heat exchanger is the heat-transfer equipment of petroleum chemical industry extensive use, all can finish by heat exchanger the cryogen heating or the high temperature fluid cooling, and heat exchanger has become exchange heat and the indispensable equipment of transmission in the chemical process realized.Development along with petroleum chemical industry, requirement to chemical industry equipment is also more and more higher, the pursuit low-cost, that high efficiency becomes people, traditional heat exchanger generally is single housing, the outer surface of the heat exchanger tube in the housing is smooth, make advantage simple, easy to maintenance although traditional shell-and-tube heat exchanger has, compare with plate type heat exchanger and still exist the problem that traditional heat exchanger volume is huge, heat exchange efficiency is low.
Three, summary of the invention:
The purpose of this utility model provides a kind of shell-and-tube heat exchanger, and this shell-and-tube heat exchanger is used for solving low, the bulky problem of conventional tube shell heat exchanger heat exchange efficiency.
The technical scheme that its technical problem that solves the utility model adopts is: two housings of this shell-and-tube heat exchanger fixedly mount side by side, are provided with heat exchanger tube in each housing, and two interior heat exchanger tubes of housing are connected, and communicate between two housings; Heat exchanger tube in each housing is by connecting portion and the integrated formation of heat exchanging segment, and the two ends of heat exchanger tube are the connecting portion of smooth outer surface, are heat exchanging segment between two connecting portions, and the heat exchanging segment outer surface is full of the screw-type projection.
The inwall of the heat exchanging segment of heat exchanger tube has metal porous layer in the such scheme.
Beneficial effect:
1, the utility model can improve heat transfer efficiency, and its heat transfer efficiency is up to 2-3 times of the conventional tube shell heat exchanger.
2, the utility model is that two heat exchangers are installed together side by side with design of heat exchanger under the constant prerequisite of heat exchanger area, and compact conformation had both been saved the space, had satisfied again the heat exchange demand.
Four, description of drawings:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of heat exchanger tube in the utility model.
On 1 upper shell, 2 lower houses 3 in the heat exchanger tube import 46 times heat exchanger tubes of 5 times heat exchanger tube imports of heat exchanger tube outlet export 7 upper shell imports, 8 upper shells and export 9 lower house imports, 10 lower houses and export 11 connecting portions, 12 heat exchanging segments, 13 metal porous layers.
Five, the specific embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1, the upper shell 1 of this shell-and-tube heat exchanger and lower house 2 fixedly mount side by side, be provided with heat exchanger tube in two housings, heat exchanger tube is fixed in the housing by gripper shoe, gripper shoe is staggered installation of on inner walls, the heat exchanger tube of upper shell 1 is connected with the heat exchanger tube of lower house 2, communicates between upper shell 1 and the lower house 2.Thermal medium enters from upper heat exchanger tube import 3, enters lower heat exchanger tube import 5 by upper heat exchanger tube outlet 4, finally discharges from lower heat exchanger tube outlet 6; Cold medium enters from upper shell import 7, enters lower house import 9 by upper shell outlet 8, finally discharges from lower house outlet 10, thereby realizes heat exchange.
As shown in Figure 2, heat exchanger tube in the utility model in each housing is by connecting portion 11 and heat exchanging segment 12 integrated formations, the two ends of heat exchanger tube are the connecting portion 11 of smooth outer surface, be heat exchanging segment 12 between two connecting portions 11, heat exchanging segment 12 outer surfaces are full of the screw-type projection, the inwall of heat exchanging segment 12 has layer of metal porous layer 13, metal porous layer 13 by powder metallurgic method at high temperature sintering form.The heat transfer system of the common smooth heat exchanger tube of ratio of heat transfer coefficient of this heat exchanger tube can improve 3 times.
