Description

Guide plate mounting structure of boiler superheater

Technical Field

The utility model particularly relates to a boiler superheater guide plate mounting structure.

Background

A superheater is a part of a boiler that heats steam from a saturation temperature to a superheat temperature, and is also called a steam superheater. The superheater can be divided into a convection type, a radiation type and a semi-radiation type according to the heat transfer mode; according to the structure characteristics, the device can be divided into a serpentine tube type, a screen type, a wall type and a wall wrapping type. They are all composed of a plurality of parallel pipes and inlet and outlet headers; because a plurality of tubes are arranged in the superheater in parallel, and more elbow joints are arranged, in the actual use process, only the tube with the corresponding length needs to be cut off and replaced after the tube at the straight tube is worn, but the elbow is connected with a plurality of tubes at the same time, the replacement and maintenance are not changed, and the engineering quantity is large, therefore, all boiler designs and manufacturers are designed, guide plates are installed above the elbow of the superheater, the direction of ash is changed, the elbow of the superheater is prevented from being worn by the ash in the flue gas, and the detailed description refers to the attached drawing figure 1 of the specification, wherein the installation structure of the existing guide plates is shown. But the guide plate is designed to be installed on a superheater pipeline and has defects, the boiler is shut down in the actual use process due to the fact that the expansion with heat and the contraction with cold are large, the welded fixed point is usually cracked, the guide plate is deformed, the boiler generally continuously runs for 6 months, the boiler cannot be processed in the running process, the elbow of the superheater pipe is abraded, and the maintenance workload is large.

A guide plate mounting structure of a boiler superheater comprises

A side wall 6;

the pipe comprises a plurality of first pipe bodies 1 and a plurality of second pipe bodies 2, wherein the first pipe bodies 1 and the second pipe bodies 2 are mutually intersected and communicated, and elbows 4 are formed at the intersection and communication positions of the first pipe bodies and the second pipe bodies; the first pipe body 1 is fixedly arranged on the side wall 6;

guide plate 3, guide plate 3 includes first plate body 31 and second plate body 32, first plate body 31 with one side fixed connection of second plate body 32, after the connection first plate body 31 with set for the contained angle has between the second plate body 32, first plate body 31 set firmly in side wall 6, just guide plate 3 will elbow 4 shields.

Further, in this embodiment, it is preferable that the set included angle between the first plate 31 and the second plate 32 is 90-130 °.

Further, in this embodiment, preferably, a plurality of avoiding channels 311 are formed at one end of the first plate 31, which is far away from the second plate 32, the avoiding channels 311 correspond to the first pipe body 1, and the size of the avoiding channels 311 is not smaller than the size of the outer contour of the first pipe body 1.
