Abstract
The utility model discloses a steam-water heat exchanger, belongs to heat exchange equipment and particularly provides a tubular shell type steam-water heat exchanger. The steam-water heat exchanger comprises a heat exchanger shell with channels at two ends. A steam inlet is arranged in one side of the shell, and a condensed water outlet is arranged in the other side of the shell. A heat exchange tube bundle is installed inside the shell. A baffle plate perpendicular to the heat exchange tube bundle is fixed by a pull rod parallel to a heat exchange tube. A water inlet and a water outlet are respectively arranged in two sides of an upper channel. The steam-water heat exchanger is characterized in that an arc-shaped scour-preventing plate is arranged between the steam inlet and the tube bundle inside the shell, and air holes are evenly distributed in the scour-preventing plate. By means of a method of forming the air holes in the scour-preventing plate, the steam-water heat exchanger has the advantages of solving the problem of heat exchange dead zones caused by arrangement of the scour-preventing plate in the tubular shell type heat exchanger, and being capable of effectively improving heat exchange efficiency and prolonging service life of the heat exchanger. Due to the technical scheme, heat exchange capacity of the heat exchanger of the same specification can be improved by 5-10% according to tests.
Description
Technical field
The utility model belongs to heat transmission equipment, particularly shell-and-tube steam and water heat exchanger.
Background technology
Shell-and-tube steam and water heat exchanger is heat transmission equipment commonly used, for the impact that prevents the tube bank of steam heat exchanging has the people to be provided with impingement baffle on the opposite of steam inlet, it is exactly that the position of impingement baffle setting exists the heat exchange dead band that but there is the drawback of a maximum in the vapor-water heat exchanger that adopts this design, especially vapor heated, if steam inlet position impingement baffle arranges and improper or too smallly causes the direct impingement heat transfer pipe of steam easily, and cause the heat exchanger tube fracture.If impingement baffle arranges excessive, the heat exchanger tube under the impingement baffle parcel just might form the heat exchange dead band, influences the heat exchange effect.
The utility model content
For existing the heat exchange dead band, the impingement baffle position that overcomes existing vapor-water heat exchanger influences the deficiency of heat exchange efficiency, the utility model provides a kind of vapor-water heat exchanger, this vapor-water heat exchanger not only can prevent the impact of steam heat exchanging tube bank, and can avoid producing the heat exchange dead band because the erosion control version is installed.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of vapor-water heat exchanger, comprise that two ends are equipped with the heat exchanger shell of bobbin carriage, housing one side is provided with steam inlet, opposite side is provided with the condensate water outlet, heat-exchanging tube bundle is housed in the housing, fixed by the pull bar parallel with heat exchanger tube with the deflection plate that heat-exchanging tube bundle is vertical, the upper tube box both sides are respectively equipped with water inlet and delivery port, it is characterized in that: be provided with the impingement baffle of circular arc in housing between steam inlet and the tube bank, impingement baffle is provided with equally distributed air-vent.
The diameter of described air-vent is identical with the thickness of impingement baffle, air-vent be equilateral triangle distribution pitch of holes be bore dia 2-4 doubly.
Described housing bottom is provided with the shell side sewage draining exit, and the lower tube box bottom is provided with the tube side sewage draining exit.
The utility model is owing to the impingement baffle that circular arc has been installed between steam inlet and tube bank, and impingement baffle is provided with equally distributed air-vent.Impingement baffle can prevent that the direct impingement heat transfer pipe of steam from causing the destruction of exchange heat pipe like this, passage can make part steam can be heated by steam equally by the tube bank that makes the impingement baffle back again, has solved in the prior art to cause the impingement baffle back problem that the heat exchange dead band influences heat exchange efficiency to occur because increased impingement baffle.Owing to the solution of the heat exchange dead-time problem that causes because of impingement baffle, in large heat exchanger, can suitably strengthen the area of impingement baffle to improve the security of heat exchanger.
The beneficial effects of the utility model have provided and have a kind ofly solved shell-and-tube heat exchanger because of the technical scheme of the problem in the heat exchange dead band that impingement baffle is set causes by the method that passage is set at impingement baffle, can effectively improve the service life of heat exchange efficiency and heat exchanger, adopting present technique according to test can be the heat exchanger raising exchange capability of heat 5-10% of same specification.

Fig. 1 is structural representation of the present utility model,
Fig. 2 be the A-A of Fig. 1 to view,
Fig. 3 is the vertical view of impingement baffle among Fig. 2,
Fig. 4 is the expanded view of impingement baffle among Fig. 2.
Among the figure, 1. steam inlet, 2. impingement baffle, 21. air-vents, 3. housing, 4. tube bank, 5. condensate water outlet, 6. exhaust outlet, 7. shell side sewage draining exit, 8. delivery port, 9. upper tube box, 10. water inlet, 11. deflection plate, 12. heat exchanger tubes, 13. pull bars, 14. lower tube box, 15. tube side sewage draining exits, 16. bearings.
The specific embodiment
The specific embodiment of the present utility model is, as shown in the figure:
Embodiment 1, a kind of vapor-water heat exchanger, comprise that two ends are equipped with the heat exchanger shell 3 of bobbin carriage, housing one side is provided with steam inlet 1, and opposite side is provided with condensate water outlet 5, and heat-exchanging tube bundle 4 is housed in the housing, fixing by the pull bar 13 parallel with heat exchanger tube 12 with the vertical deflection plate 11 of heat-exchanging tube bundle, the upper tube box both sides are respectively equipped with water inlet 10 and delivery port 8, it is characterized in that: be provided with the impingement baffle 2 of circular arc in housing between steam inlet and the tube bank, impingement baffle is provided with equally distributed air-vent 21.
Described housing bottom is provided with shell side sewage draining exit 7, and the lower tube box bottom is provided with tube side sewage draining exit 15.
Described housing bottom is provided with shell side sewage draining exit 7, and the lower tube box bottom is provided with tube side sewage draining exit 15.
The diameter of described air-vent is identical with the thickness of impingement baffle, air-vent be equilateral triangle distribution pitch of holes be bore dia 2-4 doubly.
Owing to the impingement baffle of circular arc has been installed, and impingement baffle is provided with equally distributed air-vent between steam inlet and tube bank.The steam that enters heat exchanger from steam inlet stops that impingement baffle downstream obtains buffering and enters heat exchanger, can prevent that the direct impingement heat transfer pipe of steam from causing the destruction of exchange heat pipe, passage can make part steam can be heated by steam equally by the tube bank that makes the impingement baffle back again, has solved in the prior art to cause the impingement baffle back problem that the heat exchange dead band influences heat exchange efficiency to occur because increased impingement baffle.
