Embodiment Construction
[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.
[0016] like figure 1 As shown, a hole structure on the membrane wall, the hole is quadrangular, specifically, rectangular in this embodiment. A rectangular opening is formed by an upper header tube 1 , a lower header tube 2 , a first lateral header tube 3 and a second lateral header tube 4 . The upper header pipe 1 and the lower header pipe 2 are arranged horizontally and horizontally respectively, and the first lateral header pipe 3 and the second lateral header pipe 4 are vertically arranged on the upper header pipe 1 and the lower header pipe. Both sides of header pipe 2.
[0017] The first heat exchange tubes 5 above the upper header tube 1 between the first lateral header tube 3 and the second lateral header tube 4 are welded and connected to the tube body of the upper header tube 1. The cross-sectional area of the upper he...

The invention discloses a hole structure on a membrane wall. A hole is quadrilateral, and the quadrilateral hole is formed by an upper header pipe, a lower header pipe, a first lateral header pipe anda second lateral header pipe. The upper header pipe and the lower header pipe are transversely arranged up and down, the first lateral header pipe and the second lateral header pipe are arranged on the two sides of the upper header pipe and the two sides of the lower header pipe, heat exchange pipes above the upper header pipe are welded to and communicate with a pipe body of the upper header pipe, and heat exchange pipes below the lower header pipe are welded to and communicate with a pipe body of the lower header pipe. The two ends of the upper header pipe and the two ends of the lower header pipe are welded to and communicate with the first lateral header pipe and the second lateral header pipe correspondingly, and the upper end and the lower end of the first lateral header pipe and the upper end and the lower end of the second lateral header pipe are welded to and communicate with the heat exchange pipes correspondingly. The hole structure has the beneficial effects of being simple in structure, convenient to machine, capable of effectively reducing the machining cost, regular in hole and more convenient to use.
Description
technical field [0001] The invention relates to the technical field of membrane wall boilers, in particular to membrane walls. Background technique [0002] The membrane wall is not only easy to install, but also can effectively absorb the heat of high-temperature radiation, so as to make full use of the heat of the flue gas. [0003] Based on various functional requirements, it is usually necessary to open various holes on the membrane wall, such as inspection ports and so on. At present, the openings in the membrane wall are formed by bending the heat exchange tubes. The disadvantages of bending the heat exchange tubes are: to form a hole, more heat exchange tubes need to be bent, the bending is difficult and the workload is heavy, and the holes formed by bending are irregular. Contents of the invention [0004] The object of the present invention is to provide a hole structure on the membrane wall, the hole structure is simple, easy to process and regular in shape. ...
