Abstract
The utility model provides a pair of air heater, including flange 1, heat exchange tube 2, tube sheet 3 and casing 4, 2 cross -under of heat exchange tube flange 1, both ends are connected with respectively tube sheet 3, 3 one sides of tube sheet are fixed one side of casing 4, the opposite side with be located 4 interior unsteady head 5 fixed connection of casing, float head 5 with there is the clearance in casing 4 to make tube sheet 3 can with the head 5 that floats is in together it is unsteady in the casing 4, be equipped with condensate outlet A, noncondensable gas discharge port B, D and steam inlet C on the casing 4, steam inlet C is equipped with steam inlet pipe 7, steam inlet pipe 7 with the head 5 that floats is connected. The utility model provides a pair of air heater can solve because of the difference in temperature produces stress, and the problem that makes the bond open lead to equipment to appear revealing has improved equipment safety greatly.
Description
Technical field
The utility model relates to air temperature modification technical field, particularly a kind of air heater.
Background technology
At present, along with scientific and technological progress, everybody also gets more and more to the use of air heater, front heater, due to two ends be all by welding mode steam inlet tube and end socket, heat exchanger tube, tube sheet and case weld are together, because the temperature difference is comparatively large, causes heat exchanger tube different with housing thermal expansion, easily produce stress at housing and Tube-sheet Welding place, after welding is split, revealing appears in equipment, there is very large potential safety hazard.
Utility model content
Technical problem to be solved in the utility model is to provide and solves because the temperature difference produces stress, makes bond open, causes equipment to occur a kind of air heater of leakage problem.
For solving the problems of the technologies described above, the utility model provides a kind of air heater, comprises flange 1, heat exchanger tube 2, tube sheet 3 and housing 4; Flange 1 described in the cross-under of described heat exchanger tube 2, two ends are connected to described tube sheet 3; Described tube sheet 3 side is fixed on the side of described housing 4, opposite side and be positioned at described housing 4 one float end socket 5 be fixedly connected with, there is gap with described housing 4 in described floating end socket 5, thus tube sheet 3 can be floated together with described floating end socket 5 in described housing 4; Described housing 4 is provided with condensation-water drain A, fixed gas outlet B, D and steam inlet C; Described steam inlet C is provided with steam inlet tube 7, and described steam inlet tube 7 is connected with described floating end socket 5.
Further, also comprise stuffing box sub-assembly 6, described stuffing box sub-assembly 6 is between described steam inlet tube 7 and described housing 4.
Further, described flange 1 is square.
A kind of air heater that the utility model provides, owing to being fixed tube sheet side, opposite side is fixed on floating end socket, effectively eliminates the stress between tube sheet and housing, makes the basic No leakage of equipment, substantially increases device security.
Accompanying drawing explanation
A kind of air heater front view that Fig. 1 provides for the utility model embodiment.
A kind of air heater sectional view that Fig. 2 provides for the utility model embodiment.
Detailed description of the invention
See Fig. 1, Fig. 2, the utility model embodiment provides a kind of air heater, comprises flange 1, heat exchanger tube 2, tube sheet 3 and housing 4; Heat exchanger tube 2 cross-under flange 1, two ends are connected to tube sheet 3, and concrete connected mode can be welding or be spirally connected, or other equal substitute modes.But flange 1 tube sheet 3 shape rectangle.The shape of flange 1 can be square.Housing 4 points is located at flange 1 both sides.Tube sheet 3 side is fixed on the side (specifically can welding with the end socket being welded on this housing 4 side) of housing 4, opposite side and be positioned at housing 4 one float end socket 5 be fixedly connected with, fixing mode can be described as welding or is spirally connected, or other equal substitute modes.There is the gap that floating end socket 5 can be made to float with housing 4 in the end socket 5 that floats, thus tube sheet 3 can be floated together with floating end socket 5 in housing 4.The side of housing 4 is provided with condensation-water drain A, fixed gas outlet B, D and steam inlet C; Steam inlet C is provided with steam inlet tube 7, and steam inlet tube 7 is connected with floating end socket 5.Fill at steam inlet tube 7 and housing 4 junction stuffing box sub-assembly 6, also substantially increase the sealing of equipment.
A kind of air heater that the utility model provides, owing to being fixed the side of tube sheet 3, opposite side is fixed on floating end socket 5, effectively eliminates the stress between tube sheet and housing, makes the basic No leakage of equipment, substantially increases device security.
It should be noted last that, above detailed description of the invention is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to example, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
