Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a distributor disposed in the middle of a conduit for sending pulverized coal carried by a fluid, particularly a gas, to a burner section.

[Description of prior art]

A conventional distributor will be explained with reference to FIG.

A bent pipe portion 02 is provided at the tip of a straight pipe 01 through which a solid-gas mixed phase fluid flows.

The solid-gas mixed phase fluid passes through the straight pipe 01 and passes through the bent pipe section 02.
However, in the curved pipe section 02, the fluid flows along the bend. As a result, the solid content is 0 in the bent pipe part.
2, the concentration of solids in the fixed portion on the inner wall a side of the curved pipe section 02 becomes higher than the concentration of solids on the inner wall b side of the curved pipe section 02, and as a result, each outlet of the curved pipe section 02 The solid-gas mixed phase fluid is divided into high-concentration solids and low-concentration solids and sent.

[Problem that the invention attempts to solve]

Since the conventional distributor is equipped with the bent pipe part 02,
The distributor itself has become larger and the space it occupies has also become larger. Moreover, it is necessary to change the curvature of the curved pipe portion 02 depending on the solid content to be distributed, the type of gas, the distribution ratio, etc., which poses the problem of troublesome maintenance.

[Purpose of invention]

Therefore, an object of the present invention is to provide a distributor which can reduce the space occupied by the distributor and can easily respond to changes in the fixed amount to be distributed, the type of gas, the distribution ratio, etc.

[Means for solving problems]

The present invention provides a distribution pipe in which a bifurcated distribution pipe extending in the same direction is provided at the tip of a straight pipe through which fluid flows, and at least two blocks are arranged on opposite sides of the straight pipe with their positions shifted in the fluid flow direction. We provide equipment.

[Effect of invention]

In this invention, a straight pipe through which fluid flows has two branch pipes extending in the same direction at the tip thereof, and at least two blocks are arranged on opposite sides of the straight pipe at different positions in the fluid flow direction. Since the flow of fluid in the pipe is changed by the arrangement of the blocks, the distribution of solids in the fluid can be changed.
Moreover, the distribution ratio can be easily changed by shifting the arrangement position of the blocks, changing the shape of the blocks, etc.

〔Example〕

The present invention will be explained with reference to a first embodiment shown in FIG.

A bifurcated distribution pipe 2 extending in the same direction is provided at the tip of a straight pipe 1 through which a solid-gas mixed phase fluid flows, and two blocks 3 and 4 are shifted to opposite sides of the straight pipe 1 in the fluid flow direction. Place it. Further, a guide plate 5 is arranged inside the straight pipe 1 on the upstream side of the block 4.

The solid-gas mixed phase fluid flows through blocks 3 and 3 in the straight pipe 1.
4 and the guide plate 5, the distribution of the solid air is changed, and the solid air is discharged from each outlet of the distribution pipe 2 at a specific ratio. Further, the ratio of the distribution can be easily changed by changing the structure and arrangement position of the blocks 3, 4 and the guide plate 5.

Therefore, the number of curved parts of the distributor is reduced to one, which makes it possible to downsize the distributor, reduce the space occupied by the distributor, and easily change the distribution ratio of solid air. Maintenance is also easier.

Next, the present invention will be explained with reference to a second embodiment shown in FIG. , and only the differences in operation and effect due to the different parts will be explained.

A variable block 6 that can be protruded inward and retracted inward is provided at the bifurcated portion of the distribution pipe 2, and the protrusion and insertion of the variable block 6 can be operated from the outside of the distribution pipe 2.

By providing the variable block 6, in addition to the effects obtained in the first embodiment, by adjusting the protruding position of the variable block 6, the solid-gas mixed phase fluid sent to each outlet of the distributor 2 can be distributed. It has the advantage that the ratio can be easily adjusted.

[Effect of idea]

This invention has two branch pipes extending in the same direction at the tip of a straight pipe through which fluid flows, and at least two blocks are arranged on opposite sides of the straight pipe at different positions in the fluid flow direction. This makes it possible to downsize the distributor, reducing the space occupied by the distributor, and changing the flow of fluid in the pipe by arranging the blocks, making it possible to change the distribution of solids in the fluid. This can be easily done by shifting the arrangement position, changing the shape of the block, etc., making maintenance easy.
