Abstract
The invention discloses a low-vibration tube-shell heat exchanger. The heat exchanger comprises heat exchange tubes and a tube plate. Tube holes for holding the heat exchange tubes are arranged on the tube plate and arranged with two parallel lines deviating from a horizontal or perpendicular symmetrical central line of the tube plate for different distances serving as a tube hole central line. A plurality of anti-vibration spherical protrusions are further arranged on the tube plate. Diameters of the heat exchange tubes are smaller than those of the tube holes, and the heat exchange tubes are welded with the tube holes. According to the low-vibration tube-shell heat exchanger, the tube holes are adjusted locally on the basis of conventional symmetrical distribution, and the whole tube plate forms a subtle asymmetric structure, accordingly, the tube bundle vibration state of the heat exchanger is changed, and the heat exchange capacity is improved; the plurality of the anti-vibration spherical protrusions are further arranged on the tube plate, so that interference in fluid vibration is provided, the tube plate vibration is prevented, a flow disturbing effect on the fluid is provided, and the heat transfer coefficient is improved; and the heat exchange tubes are welded with the tube holes, so that high sealing performances and strength performances are provided.
Description
Technical field
The present invention relates to heat exchanger and make the field, be specifically related to a kind of shell-and-tube heat exchanger of low vibration.
Background technology
Desalinization namely utilizes seawater desalination to produce fresh water.Be the increment technique of increasing income that realizes the water resource utilization, can increase the fresh water total amount, and not be subjected to space-time and climatic effect that water quality is good, price is gradually reasonable, can ensure stable water supplies such as coastal resident's drinking water and Industrial Boiler moisturizing.The forced condensation device is crucial heat exchanger wherein, tube side input seawater, shell side input steam, because steam flow rate is bigger, reach 13m/S, shell side has a plurality of vapour phase imports simultaneously, so just causes the vibration of heat exchanger tube, greatly reduced heat exchange effect, and reduced the service life of heat exchanger.Usually stringing design, be exactly how to arrange heat exchanger tube, make shell-side fluid flow evenly, to reach the purpose that heat exchange between the shell journey is good and save material, tube bank generally is arranged to horizontal regular hexagon, shell-side fluid and pipe are the cross-flow shape, because this layout evenly flows the most favourable to shell-side fluid.The present invention carries out part adjustment on the basis of conventional symmetry arrangement, whole tube sheet just forms delicate dissymmetrical structure, thereby changes the tube bundle vibration state of heat exchanger itself.
Summary of the invention
The object of the present invention is to provide a kind of shell-and-tube heat exchanger of low vibration,
The present invention is by the following technical solutions:
A kind of low vibrating tube shell heat exchanger comprises heat exchanger tube and tube sheet, and tube sheet is provided with the pore of arranging heat exchanger tube, it is characterized in that, arranges pore with two parallel lines that depart from tube sheet level or vertical symmetrical center line different distance as the pore center line.
Further, described distance is half to two pore diameter.
Further, pore evenly distributes in two parts that two pore center lines form, and distribution form is equilateral triangle, and the angle between each three adjacent pore line of centres is 60 °.
Further, the diameter of described pore is 19mm.
Further, also be provided with some antivibration spherical surface hills on the described tube sheet.
Further, the radius of described antivibration spherical surface hill is consistent or inconsistent.
Further, the diameter of described heat exchanger tube is less than pore diameter, and welds with pore.
Beneficial effect of the present invention:
Pore on the tube sheet of the present invention carries out part adjustment on the basis that routine is symmetrically distributed, whole tube sheet forms the dissymmetrical structure of microsecond, thereby changes the tube bundle vibration state of heat exchanger itself, improves heat-exchange capacity; The present invention also is provided with some antivibration spherical surface hills on tube sheet, have the interference fluid oscillation, prevents the tube sheet vibration, and convection cell has the effect of flow-disturbing, thereby improves heat transfer coefficient; Heat exchanger tube and pore adopt welding, have higher sealing property and strength character.
Description of drawings
Fig. 1 is tube plate structure schematic diagram of the present invention.
The specific embodiment:
Below in conjunction with accompanying drawing the present invention is done further explanation.
A kind of low vibrating tube shell heat exchanger comprises heat exchanger tube and tube sheet 1, and tube sheet 1 is provided with the pore 2 of arranging heat exchanger tube, the preferred 19mm of pore 2 diameters.The heat exchanger tube diameter is less than pore 2 diameters, preferably with pore 2 welding.Arrange pore 2 with two parallel lines that depart from tube sheet 1 level or vertical symmetrical center line different distance as pore 2 center lines, preferred half to two pore 2 diameters of distance.Pore 2 is preferred in two parts that two pore 2 center lines form evenly to distribute, and distribution form is equilateral triangle, and the angle between each three adjacent pore 2 line of centres is 60 °.Can also be provided with some antivibration spherical surface hills on the tube sheet 1, the radius of antivibration spherical surface hill is consistent or inconsistent.
With pore 2 diameter 19mm, offset level center line 9.5mm and 28.5mm are that example illustrates manufacturing process of the present invention.
Tube sheet of the present invention 1 designs according to GB151: the mark signature center line, upwards be offset 9.5mm respectively from horizontal center line, again to be offset 38mm under this alignment, (centre-to-centre spacing of adjacent two row's heat exchanger tubes is advisable so that septalium 3 can be set, the present invention is designed to 11mm) with these two center lines respectively as pore 2 center line stringings, carry out stringing by equilateral triangle, divide journey with tube sheet, every Cheng Guankong 2 quantity are equated as far as possible, draw pore 2 positions line, after stringing is finished, draw bolt hole again, the tie rod hole position line, septalium 3 positions line.When tube sheet 1 calculates, respectively in lower part stringing mode as symmetrical structure up and down, do twice calculating in top and the bottom stringing mode as symmetrical structure up and down again, by the design thickness of thicker person as tube sheet 1.
The above only is preferred embodiment of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
