Description

Structure for Prevention Collision of Boiler Tube

The present invention prevents the tube and tube which is optimally designed inside the boiler from colliding with each other due to its own shaking due to the operation of the boiler or by the conveyed material, thereby preventing the tube from being damaged and leaking accordingly. I did it.

In addition, while reducing the amount of installation of the collision preventing member to prevent the collision between the tube to reduce the material cost and manufacturing cost.

In general, an industrial boiler is a means for generating steam required for a power plant or an industrial purpose, to boil water or seawater to generate hot steam.

The hot steam generated by the boiler is fed to the turbine generator to generate the energy needed for the industry.

Looking at the components of the boiler, the boiler includes a main body for generating the necessary steam, a circulation tube for circulating or supplying steam, combustion means for supplying a heat source in the boiler through the supply and combustion of fuel, Discharge means for supplying the necessary air and for discharging the combustion gas are appropriately arranged.

1 and 2 illustrate an anti-collision structure of a general boiler tube. First, a base frame 12 is horizontally provided at one side of a fixed structure 10 installed inside the boiler. It is fixed to form a.

The base frame 12 is fixed to the corresponding side of the fixed structure 10 on the other side thereof.

In addition, the base frame 12, the first tube 14 for supplying the conveying material, specifically water, sea water, steam to the means is provided so as to penetrate in the longitudinal direction at a predetermined interval. The first tube 14 is welded with the base frame 12 to fix the position.

In addition, both sides of the first tube 14 are installed such that a plurality of second tubes 16 for conveying the conveyed object pass in the transverse direction with a predetermined interval from each other in a stacked state. There is a minimum gap L between the second tube 16 and the first tube 14.

The second tube 16 is connected to an integrated tube 18 that is made up of one piece to finally collect the conveyed material.

For reference, although not shown in the drawing, the first tube 14 is also connected to another integrated tube to collect the conveyed material.

In addition, the outer side of the second tube 16 is provided with an anti-collision member 20 made of a steel plate to accommodate all the stacked second tube 16, wherein the second tube 16 is a collision preventing member ( 20) passes in contact with each other and is not fixed to each other by welding. The anti-collision member 20 has both ends 22 welded to the base frame 12.

The first and second tubes 14 and 16 are each bent as they are thermally expanded by their own shaking due to the operation of the boiler or by the conveyed material. The distance L between the first tube 14 and the second tube 16 is increased. This narrows, and may try to collide with each other by shaking.

At this time, the anti-collision member 20 provided in the second tube 16 is holding the second tube 16, thereby preventing the collision between the first tube 14 and the second tube (16). do.

However, the collision preventing member 20 is installed in an arrangement structure for holding the second tube 16, so that the second tube 16 is installed more than the first tube 14, the collision preventing member ( The installation quantity of 20) naturally increases, and it is difficult to reduce the material cost and the manufacturing cost of the collision preventing member 20 with this arrangement.

When the collision preventing member 20 is not used to solve this problem, a method of further separating the gap L so as not to cause a collision between the first tube 14 and the second tube 16 may be considered. However, if the gap L is made larger, the installation space occupied by the first and second tubes 14 and 16 becomes large, and thus, it is difficult to optimize the design, thereby increasing the size of the boiler.

Therefore, the structure for minimizing the number of installation of the impact preventing member 20 to reduce the material cost and manufacturing cost while maintaining the optimized design of the first and second tubes (14, 16).

The present invention is designed to solve the above problems, and prevents the tube and the tube which is optimally disposed inside the boiler from colliding with each other by its own shaking or conveyed by the operation of the boiler, and the collision An object of the present invention is to reduce the number of installation of the prevention member to reduce the material cost and manufacturing cost.

The present invention for achieving the above object is installed in a state in which the collision preventing member is wrapped around the outer circumferential surface of the first tube by a predetermined length on the base frame so that the second tube is in contact with both sides of the outer side of the collision preventing member to pass through. Thus, there is a technical feature that the collision preventing member of the boiler tube is provided by the collision preventing member to maintain the gap between the first tube and the second tube to prevent the collision.

In addition, the anti-collision member is formed in a 'U' shape is configured to partially wrap the outer peripheral surface of the first tube.

In addition, the anti-collision member is formed in a circular structure to surround the entire outer peripheral surface of the first tube.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Example 1

As shown in FIGS. 3A and 3B, the first tube 14 penetrates the base frame 12 in the longitudinal direction and is laterally adjacent to both sides of the first tube 14. In the second tube 16 passing in the direction, the outer surface of the first tube 14 is installed in a state in which the collision preventing member 40 made of iron plate directly wrapped so that one side of the collision preventing member 40 It is placed on the upper surface of the base frame 12.

In addition, the surface on which the collision preventing member 40 is placed and the base frame 12 are welded to each other. The anti-collision member 40 is formed in a "U" shape as shown in Figure 3 (c) is made to partially wrap the outer peripheral surface of the first tube (14).

In addition, the inner surface of the collision preventing member 40 is formed of a curved surface 42 having the same curvature as the curved surface of the first tube 14 so that there is no vibration between the first tube 14 and the collision preventing member 20. It is desirable to.

Then, both sides of the anti-collision member 40 are passed through the second tube 16 in contact with each other to maintain the optimized design. The reason why the second tube 16 is in contact with the collision preventing member 40 passes through the first tube 14 and the second tube when the second tube 16 is spaced apart from the collision preventing member 40 and the second tube 16. This is because it is difficult to maintain an optimized design between the tubes 16, which results in a larger boiler. Therefore, the second tube 16 is disposed to contact the side of the collision avoidance member 40.

Example 2

As illustrated in FIGS. 4A and 4B, an anti-collision member 50 is installed in the first tube 14 so as to receive an outer circumferential surface thereof. One side is placed on the upper surface of the base frame 12, and the surface on which the collision preventing member 50 is placed and the base frame 12 is fixed to each other by welding.

As shown in FIG. 4 (c), the receiving hole 52 is formed in a circular shape to surround the outer circumferential surface of the first tube 14, and the receiving hole 52 is formed inside the collision preventing member 50. Silver is preferably formed in the same shape as the shape of the first tube (14).

Then, both sides of the collision preventing member 40 is passed in a state in which the second tube 16 is in contact with each other in order to maintain an optimized design, and the collision preventing member 50 and the second tube 16 are welded. Do not fix

Therefore, the impact preventing members 40 and 50 are not separately installed in the second tube 16 as described above, but the first and second states of the first and second tubes 14 and 16 are maintained. The outer circumferential surface of the tube 14 is partially or partially wrapped to maintain the minimum distance L between the first and second tubes 14 and 16, thereby preventing the occurrence of a collision.

In addition, since the first tube 14 has a smaller number of installations than the second tube 16, the number of installation of the collision preventing members 40 and 50 is naturally reduced, thereby reducing material costs and manufacturing costs.

Particularly, the anti-collision member 40 shown in FIG. 3 (b) is fixed to the base frame 12 while partially covering the outer circumferential surface of the first tube 14, and is also attached to the exemplary drawing. The anti-collision member 50 shown in FIG. 4 (b) is welded and fixed to the base frame 12 while completely covering the outer circumferential surface of the first tube 14.

Therefore, when the first tube 14 is about to bend due to expansion, the bending is prevented by the collision preventing members 40 and 50.

Accordingly, the minimum spacing L is more stably maintained between the first tube 14 and the second tube 16, so that the optimization according to the arrangement of the first and second tubes 14 and 16 can be achieved.

As described above, the present invention is installed in a state in which a collision preventing member surrounds part or all of the outer circumferential surface of the first tube, thereby preventing collision between the first and second tubes by the collision preventing member, thereby preventing damage to the tube. It is effective.

In addition, the anti-collision member is fixed to the base frame to surround the first tube, thereby preventing the first tube from bending due to thermal expansion.

In addition, while maintaining the optimum design between the first tube and the second tube to prevent the collision between the tubes with a minimum amount of installation, there is an effect that can reduce the material cost and manufacturing cost according to the production of the collision preventing member. .

In addition, the amount of installation of the anti-collision member is reduced can be expected to reduce the installation time.
