Detailed Description
Embodiment one: referring to fig. 1, a 1-flashboard cavity, a 2-baffle plate, a 3-water inlet pipe, a 4-lifting lug and a 5-water outlet pipe are shown.
High temperature resistant long life flue flashboard contains flashboard cavity 1, is provided with lug 4 on the flashboard cavity 1, wherein: the flashboard cavity 1 is a hollow cuboid structure formed by welding surrounding steel plates in sequence, at least one baffle plate 2 (one baffle plate is arranged in the flashboard cavity 1, two baffle plates, three baffle plates are arranged according to the size of the flashboard cavity, generally, one baffle plate is arranged at intervals of about one meter), the baffle plate 2 enables the flashboard cavity 1 to be divided into mutually independent cavities, the upper end of each cavity is respectively provided with a water inlet pipe 3 and a water outlet pipe 5, the lower end of the water inlet pipe 3 is close to the bottom surface of the cavity, a distance of 15-20cm is reserved between the lower end of the water inlet pipe 3 and the bottom surface of the cavity, preferably 15cm is reserved, and the arrangement can enable cold water to be directly led to the bottom, so that the cooling effect is improved.
The preferable scheme is as follows: for the case that the flashboard cavity 1 is relatively large and/or the steel plate is relatively thin, longitudinal reinforcing rib plates and transverse reinforcing rib plates (not shown in the drawing) are arranged in the inner cavity of each cavity, so that the deformation of the plate surface of the cavity is prevented. Of course, an auxiliary support plate can be arranged between the lower end of the water inlet pipe 3 and the inner wall of the chamber to prevent the position of the water inlet pipe 3 from deforming.
The preferable scheme is as follows: the water inlet pipe 3 and the water outlet pipe 5 are all made of metal pipes with the diameter of 65mm, and the wall plate of the flashboard cavity 1 is made of stainless steel plates with the thickness of 16 mm.
