Abstract
The utility model discloses a baffling device used for tubular and U-shaped heat exchanger and comprises a baffling plate body group which consists of at least two baffling plate bodies which are arranged in turn, the baffling plate bodies are provided with orifices for heat exchange tube banks to pass through, the baffling plate bodies are symmetrically provided with fan-shaped overflowing areas, and the fan-shaped overflowing areas of two adjacent baffling plate bodies are mutually vertical in space. Two adjacent baffling plate bodies with one being provided with an overflowing hole on the center are preferable. The flowing speed of fluid is evenly distributed on the whole section when the fluid passes through the baffling plate bodies during the operating process of a heat exchanger, and dead water area can not appear, thereby improving heat exchanging efficiency and corrosion prevention performance of the heat exchanger, and prolonging the service life of the heat exchanger.
Description
Technical field
The utility model relates to a kind of baffle means, relates in particular to a kind of baffle means that is used for tubulation and U type heat exchange of heat pipe.
Background technology
The deflection plate of existing tubulation and U type heat exchange of heat pipe shell-side is generally circle and lacks shape or annular, and during the heat exchanger operation, fluid flows through from circle is scarce, the circle that folds to down a slice deflection plate again lacks the place, in flow process, because the variation of circulation area reduces at the Kuan Mianchu flow velocity, the slough appears in the outside simultaneously, flow velocity is more slow, and heat exchange efficiency descends, and heat exchanger volume is big, the slough seriously corroded, the heat exchanger lost of life.
The utility model content
Technical problem to be solved in the utility model is to exist heat exchange efficiency to descend at the tubulation of scarce shape of existing employing circle or annular deflection plate and U type heat exchange of heat pipe, heat exchanger volume is big, the slough seriously corroded, defectives such as the heat exchanger life-span is short, thus a kind of efficient energy-saving, province's material, the baffle means that is used for tubulation and U type heat exchange of heat pipe in corrosion-resistant prolongation heat exchanger life-span are provided.
For solving the problems of the technologies described above, the technical solution of the utility model is: the baffle means that is used for tubulation and U type heat exchange of heat pipe, comprise that at least two baffling plate bodys are arranged in order the baffling plate body group of composition, described baffling plate body is provided with the pore that passes through for heat-exchanging tube bundle, be arranged with fan-shaped overcurrent district on the described baffling plate body, the described fan-shaped overcurrent district of described adjacent two baffling plate bodys is spatially vertical mutually.
As optimized technical scheme, be interval with the center flowing hole on the described baffling plate body of described baffling plate body group.
As further optimized technical scheme, described center flowing hole is circular.
As optimized technical scheme, described pore is circular.
As optimized technical scheme, total area of passage of described adjacent two baffling plate bodys equates.
Owing to adopted technique scheme, the baffle means that is used for tubulation and U type heat exchange of heat pipe, comprise that at least two baffling plate bodys are arranged in order the baffling plate body group of composition, described baffling plate body is provided with the pore that passes through for heat-exchanging tube bundle, be arranged with fan-shaped overcurrent district on the described baffling plate body, the described fan-shaped overcurrent district of described adjacent two baffling plate bodys is spatially vertical mutually.In the heat exchanger running, fluid during by the baffling plate body flow velocity in whole end face, be evenly distributed, the slough can not occur, thereby improve the heat exchange efficiency and the decay resistance of heat exchanger.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the baffling plate body of a kind of template among the utility model embodiment;
Fig. 2 be among the utility model embodiment with Fig. 1 in the structural representation of the adjacent baffling plate body of baffling plate body;
Among the figure: 1-baffling plate body, 2-pore, 3-center flowing hole, 4-overcurrent district.
The specific embodiment
As shown in Figure 1 and Figure 2, this baffle means comprises that at least two baffling plate bodys 1 are arranged in order the baffling plate body group of composition, baffling plate body 1 is provided with the pore 2 that passes for the heat exchanger tube in the heat exchanger, the bilateral symmetry of baffling plate body 1 is provided with fan-shaped overcurrent district 4, and the area of passage in all fan-shaped overcurrent districts equates.The difference of Fig. 2 and Fig. 1 only is: the center position of baffling plate body 1 shown in Figure 2 is provided with center flowing hole 4, with so that fluid by preventing the slough.
As shown in Figure 1 and Figure 2, the baffling plate body 1 among the utility model embodiment is installed along being installed as alternately on the heat-exchanging tube bundle length direction in heat exchanger, and promptly the fan-shaped overcurrent district 4 of two adjacent baffling plate bodys 1 is spatially vertical mutually arbitrarily.
This baffle means is adding man-hour, the number of pore 2 is corresponding with the radical of heat exchanger tube in the heat exchanger on the baffling plate body 1, the arrangement mode of pore 2 is consistent with tube bank in the heat exchanger, employed baffling plate body need be fixed together and join brill on same the heat exchanger, the pore two sides needs chamfering after the boring, the pore edge chamfer is 3 * 45 °, and still is fixed together behind brill, stamps steel seal to guarantee the uniformity of all baffling plate bodys.
Use the tubulation of this baffle means and U type heat exchange of heat pipe in running, fluid during by the baffling plate body flow velocity in whole section, be evenly distributed, the slough can not occur, thereby improve the heat exchange efficiency and the decay resistance of heat exchanger, prolong the life-span of heat exchanger.
Claims (5)
