Abstract

PURPOSE:To miniaturize the drive system for a lance pipe of the soot blower and to smplify the lance pipe support structure by a method wherein a cylindrical section which is rotated by steam injected through the lance pipe is provided on the top end of the lance pipe. CONSTITUTION:The rotary cylindrical section 22, a shaft 23 and wings 24 are connected together integrally; bearings 26, 29, spacers 27, 30, a seal 32 and a stopper 33 are fitted in the lance pipe 2; and a stopper 25 is removably connected to the lance pipe. The steam blown through the lance pipe from the left as shown by the arrow flows along a steam guide inner cylinder 28 provided inside the lance pipe and is sprayed onto the wings 24 provided on the shaft 23 so that the cylindrical section 22 rotates by the power of steam. Further, as the lance pipe performs linear motions, it is possible to inject the steam from a fluid injection hole 7 drilled in the side surface of the cylindrical section with the steam made to draw a helical locus.

Now, in order to remove the soot attached to the tube in the boiler by the steam ejected from the nozzle opening at the tip of the lance tube (force), it is necessary to apply not only a linear movement in the front and back direction but also a rotational movement. It is necessary to spray steam over a wide area.For this purpose, the lance tube drive system (1) needs to supply power that can give linear and rotational motion to the lance tube.In addition, the grooved beam (3 The structure of the lance tube support (6) at the tip of the lance tube (6) is also complex so that both rotational and linear movement is possible.

Problems such as outbreaks were occurring. As described above, in the conventional structure, in order to rotate the opening at the tip of the lance tube, the entire lance tube is rotated, so the structure is complicated.

Next, to explain the operation, the arrows in FIG. 4 indicate the flow of steam. Now, first of all, the steam blown into the lance pipe (2) from the left side as shown by the arrow flows along the steam guide cylinder provided inside the lance pipe (2), and flows through the rotating cylindrical part (inside the two The shaft attached to the bottom is blown onto the rotating cylindrical part (2). A force is applied, and the blade (2 (A)), the shaft (2 (To)), the rotating cylinder part (221
Since they are integral, the rotating cylindrical part (2) attached to the tip of the lance tube (2) rotates around the axis of the lance tube (2). Therefore, the rotating cylindrical part (the steam in the two bottom parts B rotates The lance tube (2) does not rotate, but the cylindrical portion at the tip of the lance tube (by rotating, the lance tube (2) opens into the cylindrical portion (22) Since the bearing has forces in the thrust direction and lateral direction, the bearing t
26) 09) is installed between the lance tube (2) and the rotating cylindrical part (2).The bearing deteriorates in function when it becomes high temperature, so it needs to be cooled (temperature inside the boiler: approx. °C1 ejection steam temperature: approx. 200-800°
C) For this purpose, steam is passed through the bearing C) G) (291) by providing a steam vent hole 01). However, from the bottom B' of the rotating cylinder, the lance pipe (2) Since leakage of steam to section C must be prevented, a seal section 0, for example a labyrinth seal, is used between the bearing 09) and the mating end section C.

In this way, the steam blown inside the non-rotating lance tube (2) is ejected from the opening (7) provided in the cylindrical portion (2) at the tip of the lance tube while drawing a spiral trajectory. This means that the lance tube moves in a straight line back and forth, and the cylindrical part (22) attached to the tip of the lance tube
This is because the rotational motion is caused by the power of steam.
