Abstract
The present invention relates to boiler superheater piping to hang technical field, it is specially a kind of to be used for boiler superheater hanging cartridge structure, it can solve the problem that connection heat transfer and thermal expansion problem, ensure normal operation, it includes backplate and superheater pipe clamp, it is characterized in that, described superheater pipe clamp connection bearing rib one end, the bearing rib other end is T-shaped head, bottom plate is installed on the backplate, it is close to the vertical bars of the backplate in the side at the first end of T-shaped of the bearing rib, bottom supporting is in the bottom plate upper surface, two are also equipped with the bottom plate to be arranged in the T-shaped head both sides and be close to the angular hook plate of the T-shaped head.
Description
Technical field
The present invention relates to boiler superheater piping to hang technical field, is specially that a kind of boiler superheater that is used for hangs deck
Structure.
Background technology
There is the superheater of part boiler tail at present using hanging pipe pendant, as shown in Figure 1, superheater area flue-gas temperature
800 DEG C or so, hanging pipe can use water cooling or vapour it is cold, so hang pipe using water cooling or vapour it is cold but after, it is ensured that by force
Degree and safety.But because hanging pipe uses pipe（Not less than φ 42）, certain space can be accounted for, so between superheater pipe
Away from can not be too small.So, superheater is just forced to use in-line arrangement mode, the superheater ratio of heat transfer coefficient mistake of in-line arrangement
The superheater heat transfer coefficient of row arrangement is low, and the area arrangement of superheater can be made more；Meanwhile because between the superheater of in-line arrangement
Away from can not be too small, so velocity of flue gas with regard to relatively low, can also influence heat transfer coefficient；The easy dust stratification of superheater of in-line arrangement, influence
Heat transfer coefficient.
If superheater is hung using pipe clamp, can solve the above problems, two panels pipe clamp thickness only has 8mm, so, mistake
Hot device can be used and is staggered in arrangement, it is also ensured that velocity of flue gas, improve the heat transfer coefficient of superheater.But the fixation of pipe clamp is
Individual problem, because in high-temperature region, if using ventilation beam form, ventilation beam must use exotic material, and need logical
Very thick flame-proof thermal insulation material is beaten around wind beam, ventilation beam can block flue, influence to conduct heat.If pipe clamp is fixed by gusset
It is welded on backplate, hanging gusset temperature is very high, and heat can be delivered on backplate by welding, and backplate surrounding is welded with pillar,
Backplate can not free wxpansion, can so cause structure problem.
The content of the invention
In order to solve the above problems, the invention provides one kind to be used for boiler superheater hanging cartridge structure, and it can be solved
Certainly connection heat transfer and thermal expansion problem, ensure normal operation.
Its technical scheme is such：One kind is used for boiler superheater hanging cartridge structure, and it includes backplate and superheater
Pipe clamp, it is characterised in that described superheater pipe clamp connection bearing rib one end, the bearing rib other end is T-shaped head, described
Bottom plate is installed, the vertical bars of the backplate, bottom supporting are close in institute in the side at the first end of T-shaped of the bearing rib on backplate
Bottom plate upper surface is stated, two are also equipped with the bottom plate and is arranged in the T-shaped head both sides and is close to the angular hook of the T-shaped head
Plate.
It is further characterized by, and the bearing rib is T-shaped gusset；
The angular hook plate weld is in the vertical bars of the backplate；
The superheater pipe clamp connects the bearing rib by riser.
After structure using the present invention, in T-shaped head both sides, it is real together with bottom plate can to catch on T-shaped head for the angular hook plate of arrangement
The fixation of existing bearing rib, while bearing rib and angular hook plate, bottom plate, the vertical bars of backplate are not welded, and contact surface is little,
Then thermal contact resistance is very big, and the heat on bearing rib is just not easy to be transferred on backplate, and backplate side is exposed in air, can
To be winding is effectively cooled, solve connection heat transfer problem, can be swollen upwards after being heated because bearing rib upper end is free state
It is swollen, thermal expansion is solve thed problems, such as, ensure that normal operation；Angular hook plate weld company of strengthening after in the vertical bars of backplate
Intensity is connect, further realizes the stable fixation of bearing rib.

Fig. 2 is schematic structural view of the invention；
Fig. 3 be in Fig. 2 A-A to profile；
Fig. 4 is enlarged diagram at A in Fig. 3.
Embodiment
See Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4, one kind is used for boiler superheater hanging cartridge structure, and it includes backplate 1 and mistake
Hot device pipe clamp 2, superheater pipe clamp 2 are welded in the one end of bearing rib 4 by riser 3, and bearing rib 4 is T-shaped gusset, one end T
Forming head, is provided with bottom plate 5 on backplate 1, the side at the first end of T-shaped of bearing rib 4 be close to the vertical bars 7 of backplate 1, bottom supporting in
The upper surface of bottom plate 5, for transmitting the vertical load of bearing rib 4, be also equipped with bottom plate 5 two be arranged in T-shaped head both sides and
It is close to the angular hook plate 6 of T-shaped head, transmits the eccentric bending moment of bearing rib 4, the angular vertical bars 7 for hooking plate 6 and being welded in backplate 1.
Claims (4)
