Abstract
A tubular heat exchanger comprises a shell body, wherein an upper tube box is arranged at the upper end of the shell body, the lower end of the shell body is provided with a lower tube box, a central tube is arranged in the shell body along the central axis of the shell body, and heat exchange tubes are arranged on the central tube, and are tightly wound on the central tube. The upper tube box is provided with an upper tube plate, the lower tube box is provided with a lower tube plate, and the two ends of the central tube are respectively connected with the upper tube plate and the lower tube plate. The heat exchange tubes are fixed on the central tube through tube hoops. A division bar is arranged between the heat exchange tubes, and is connected to the heat exchange tubes through the tube clamps. The tubular heat exchanger has a compact structure, a unit volume has larger heat transfer area, the operating pressure in the tube is high, the thermal expansion of the heat exchange tubes which are adopted can be automatically compensated, and a large scale production is easy to realize.
Description
Technical field
The utility model relates to a kind of heat transmission equipment, especially relate to a kind of pipe heat exchanger.
Background technology
Heat exchanger (heat exchanger) is with the equipment of the part heat transferred cold fluid of hot fluid, claims heat exchanger again.Heat exchanger is the common apparatus of chemical industry, oil, power, food and other many industrial departments, occupies critical role aborning.Heat exchanger can be used as heater, cooler, condenser, evaporimeter and reboiler etc. in Chemical Manufacture, uses more extensive.The heat exchanger kind is a lot, but can divide three major types basically according to the principle and the mode of cold and hot fluid exchange heat: dividing wall type, hybrid and heat accumulating type.In three class heat exchangers, dividing wall type heat exchanger is used at most.
Shell-and-tube (claiming shell and tube again) heat exchanger is most typical dividing wall type heat exchanger, and it has long history in industrial application, and dominate in all heat exchangers still so far.Shell-and-tube heat exchanger mainly contains housing, tube bank, tube sheet and end socket etc. partly to be formed, and how rounded housing is, and bundle of parallel tubes is equipped with in inside, and the tube bank two ends are fixed on the tube sheet.Carry out two kinds of fluids of heat exchange in shell-and-tube heat exchanger, a kind of mobile in pipe, its stroke is called tube side, and a kind of mobile outside pipe, its stroke is called shell side, and the wall of tube bank is heat-transfer area.Be to improve the extratubal fluid heat transfer coefficient, the horizontal baffle plate of some is installed in housing usually, baffle plate not only can prevent the fluid short circuit, increases fluid velocity, also force fluid in accordance with regulations the path repeatedly cross-flow by tube bank less turbulence is greatly increased.Plate washer commonly used has circle to lack two kinds of shape and discs, and the former uses more extensive.Fluid whenever once is called a tube side by tube bank in pipe, whenever once be called a shell side by housing.For improving the speed of tube fluid, suitable dividing plate can be set in the end socket of two ends, whole pipe average marks are divided into some groups, like this, fluid can only come and go tube bank repeatedly by the part pipe at every turn, is called the multitube journey; Equally,, vertical plate washer can be installed in housing make fluid, claim muitishell repeatedly by shell space for improving the outer flow velocity of pipe.
In shell-and-tube heat exchanger, because the inside and outside fluid temperature (F.T.) difference of pipe, the temperature of housing and tube bank is also different, very big as both temperature difference, very big thermal stress will appear in heat exchanger inside, may make tube bending, fracture or get loose from tube sheet, therefore, when tube bank and case temperature difference above 50 ℃ the time, should take suitable temperature difference compensation measure, eliminate or reduce thermal stress.
The utility model content
Be the defective that solves the problems of the technologies described above, the purpose of this utility model is to be to provide a kind of compact conformation, and unit volume has the pipe heat exchanger of bigger heat transfer area, the phenomenon of having avoided tube bending, fracture or having got loose from tube sheet.
The utility model is that the technical scheme that its technical problem of solution is adopted is:
Pipe heat exchanger includes housing, and described housing upper end is provided with upper tube box, and the lower end is provided with lower tube box, is provided with central tube in enclosure interior along the axis of this housing, and central tube is provided with heat exchanger tube, and this heat exchanger tube closely is wrapped on the central tube.
Aforesaid a kind of pipe heat exchanger, wherein, described upper tube box has upper perforated plate, and described lower tube box has lower perforated plate, and the two ends of described central tube are connected to upper perforated plate and lower perforated plate.
Aforesaid a kind of pipe heat exchanger, wherein, described heat exchanger tube is fixed on the central tube with pipe collar.
Aforesaid a kind of pipe heat exchanger wherein, is provided with parting bead between the described heat exchanger tube, and parting bead is connected in heat exchanger tube with pipe clamp.
The beneficial effects of the utility model are, this pipe heat exchanger compact conformation, and unit volume has bigger heat transfer area, the operating pressure height in the pipe, the thermal expansion of employed heat-transfer pipe can compensate voluntarily, realizes easily maximizing.
Description of drawings
Fig. 1 is the structural representation of the utility model pipe heat exchanger.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose with effect is easy to understand, below in conjunction with illustrating and specific embodiment, further set forth the utility model.
As shown in Figure 1, the pipe heat exchanger that the utility model proposes includes housing 100, in the upper end of housing 100 upper tube box 110 is installed, and the lower end is equipped with lower tube box 120; Axis in housing 100 inside along this housing is provided with central tube 130, this central tube 130 is provided with heat exchanger tube 131, this heat exchanger tube 131 closely is wrapped on the central tube 130, make its unit volume have bigger heat transfer area by this mechanism, the phenomenon of having avoided tube bending, fracture or having got loose from tube sheet.
In the present embodiment, described upper tube box 110 has upper perforated plate 111, and described lower tube box 120 has lower perforated plate 121, and the two ends of described central tube 130 are connected to upper perforated plate 111 and lower perforated plate 121.
Be fixed on the central tube 130 at heat exchanger tube 131 usefulness pipe collars, increased the central tube mounting stability.
In addition, it should be noted that between the heat exchanger tube 131 to be provided with parting bead that parting bead is connected in heat exchanger tube 131 with pipe clamp.
Based on above-mentioned, the utility model pipe heat exchanger compact conformation, unit volume has bigger heat transfer area, operating pressure height in the pipe, the thermal expansion of employed heat-transfer pipe can compensate voluntarily, realizes easily maximizing the phenomenon of having avoided tube bending, fracture or having got loose from tube sheet.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.
