Description

A kind of U-tube arrangement mounting structure of tubular sheet heat exchanger
Technical field
The utility model relates to tubular sheet heat exchanger technical field, especially a kind of U-tube arrangement mounting structure of tubular sheet heat exchanger.
Background technology
In tubular heat exchanger, major embodiment be the heat transfer problem of two kinds of cold fluid and hot fluids, the problem that namely heat exchanger heat exchange area is large and small, defines the minimum bending radius R of U-tube bend loss, R=1/2H in GB151-1999.In actual applications, tubular heat exchanger often can run into following several problem: 1, tubulation diameter is little, and soil-pipe interaction quantity is few, and heat exchange area is just little; 2, the minimum bending radius R of U-tube bend loss is little, the problem of bad stewing pipe in actual production operation.
Summary of the invention
The purpose of this utility model is to make up the deficiencies in the prior art part, the U-tube arrangement mounting structure providing a kind of and can increase heat exchange area, reduce the tubular sheet heat exchanger simmering pipe difficulty.
The purpose of this utility model is realized by following technological means:
A kind of U-tube arrangement mounting structure of tubular sheet heat exchanger, comprise tube sheet and U-tube, septalium is made at the middle part of tube sheet, uniformly on the tube sheet of septalium both sides make multiple pore, tube sheet is installed and arranges U-tube more, the two ends of each U-tube are arranged in the pore of septalium both sides respectively, it is characterized in that: be positioned at the U-tube of first row for being obliquely installed, and the pore of its two ends institute plug-in mounting is for shifting to install.
And, on the left of described first row, the two ends of first U-tube are inserted in the 3rd pore of first pore and downside on the upside of septalium respectively, on the left of first row, the two ends of second U-tube are inserted in the 4th pore of second pore and downside on the upside of septalium respectively, and the rest may be inferred for the mounting means of other U-shaped pipes of first row.
Advantage of the present utility model and good effect are:
1, in this arrangement mounting structure the U-tube of first row for being obliquely installed, its hypotenuse is minimum bending radius, therefore relative to traditional vertical set-up mode, when obtaining same minimum bending radius, this structure is adopted to be equivalent to decrease the centre distance H of septalium both sides adjacent tubes, therefore make soil-pipe interaction increasing number, finally make the increase of tubular heat exchanger heat exchange area, heat transfer effect enhancing.
2, this arrangement mounting structure increases U-tube minimum bending radius C, simmers pipe and operates conveniently, thus reduces operation easier, improve production efficiency and ensure that product quality.
3, the utility model is the U-tube arrangement mounting structure of ingenious, the simple and reasonable tubular sheet heat exchanger of a kind of design science, adopt this mounting structure can strengthen stringing quantity, increase heat exchange area, reduce stewing pipe difficulty, enhance productivity, in production application, obtain good effect.
Accompanying drawing illustrates:
Fig. 1 is tube bank arrangement figure of the present utility model;
Fig. 2 is soil-pipe interaction figure of the present utility model.
Detailed description of the invention
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing; It should be noted that, the present embodiment is narrative, is not determinate, can not limit protection domain of the present utility model with this.
A kind of U-tube arrangement mounting structure of tubular sheet heat exchanger, comprise tube sheet 3 and U-tube, septalium 5 is made at the middle part of tube sheet, uniformly on the tube sheet of septalium both sides makes multiple pore 4, tube sheet is installed and arranges U-tube more, the two ends of each U-tube are arranged in the pore of septalium both sides respectively.
Innovative point of the present utility model is: be positioned at the U-tube 2 of first row for being obliquely installed, and the pore of its two ends institute plug-in mounting, for shifting to install, is not symmetrical arranged.That is: on the left of first row, the two ends of first U-tube are inserted in the 3rd pore of first pore and downside on the upside of septalium respectively, on the left of first row, the two ends of second U-tube are inserted in the 4th pore of second pore and downside on the upside of septalium respectively, and the rest may be inferred for the mounting means of other U-shaped pipes of first row.The U-tube 1 of other rows still adopts traditional vertical mounting structure.
Operation principle of the present utility model is:
First row U-tube stringing is that inclination shifts to install, and its minimum bending radius is the hypotenuse C of right angled triangle, the right angled triangle namely in Fig. 2.With tube sheet median septum groove both sides adjacent tubes centre distance H with wherein the distance A of three pores is for right-angle side in first row pore, C is hypotenuse (as shown in Figure 2), can try to achieve C by the principle of Pythagorean theorem.
As shown in the above, when ensureing that the minimum bending radius C of first row U-tube bend loss meets processing request, the centre distance H of first row U-tube in tube sheet median septum groove both sides adjacent tubes suitably can be reduced.Because first row U-tube reduces at septalium both sides adjacent tubes centre distance H, therefore other row's U-tube also can reduce in septalium both sides adjacent tubes centre distance thereupon, stringing can be compacter, therefore can arrange more U-tube with on the tube sheet of homalographic, thus add heat exchange area.
