Technical Field

The invention relates to a chilling ring structure, in particular to a novel chilling ring structure for a coal water slurry gasifier, and belongs to the technical field of coal water slurry gasifiers.

Background

The chilling ring commonly used for the water-coal-slurry gasification furnace has a special main body structure, the whole body is commonly manufactured by adopting a whole forging piece, the consumption of raw materials is large, and the manufacturing cost is high. The chilling ring channel is made of a semi-circular ring pipe, has large thermal deformation in the processing and welding process, is difficult to correct, and easily causes uneven water distribution of the chilling ring. Because the area of the chilling water channel is not large, the risk of blockage is easy to exist in the long-period operation process, and the operation period of the gasification furnace is influenced.

Disclosure of Invention

The invention aims to solve the problems of high manufacturing cost, high manufacturing difficulty and short operation life of the existing chilling ring for the coal water slurry gasifier, and further provides a spiral water-cooling slag tapping pipe for a circulating fluidized bed boiler, so as to reduce the cost of the chilling ring and prolong the service life of the chilling ring.

The technical scheme adopted by the invention for solving the problems is as follows:

the chilling ring structure for the coal water slurry gasification furnace comprises a first connecting flange, and further comprises an outer ring component and an inner ring component, wherein the outer ring component is connected with the first connecting flange, the inner ring component is connected with the upper end of a descending cylinder of the coal water slurry gasification furnace, and the outer ring component is connected with the inner ring component.

Furthermore, the outer ring component is composed of an outer upper ring plate, an outer side plate and an outer lower ring plate, the outer upper ring plate, the outer side plate and the outer lower ring plate are sequentially connected end to form a first C-shaped structure, and the outer upper ring plate is fixedly connected with the first connecting flange.

Furthermore, a bevel cut is arranged between the outer side of the outer lower ring plate and the inner wall of the descending cylinder.

Furthermore, the inner ring component comprises an inner upper ring plate, an inner side plate and an inner lower ring plate, the inner upper ring plate, the inner side plate and the inner lower ring plate are sequentially connected end to form a second C-shaped structure, the second C-shaped structure is embedded in the first C-shaped structure, and the inner upper ring plate and the inner lower ring plate are fixedly connected with the inner wall of the descending cylinder.

Furthermore, a plurality of obliquely arranged partition plates are uniformly distributed between the outer upper ring plate and the inner upper ring plate.

Further, the partition plate is inclined at an angle of 25 ° to 35 °.

Furthermore, the chilling ring structure for the coal water slurry gasifier further comprises a chilling water inlet pipeline and a second connecting flange, one end of the chilling water inlet pipeline is welded with the first connecting flange, and the other end of the chilling water inlet pipeline is welded with the second connecting flange.

The invention has the beneficial effects that:

1. except the first connecting flange 1, other parts are welded by adopting plates, the overall quality is reduced by 30 percent, the manufacturing cost is reduced, and the distribution space of chilled water is enlarged.

2. Through the arrangement of the partition plate 8, the chilling water is distributed in a rotating tangential direction after entering, so that the disturbance of water flow is increased, and the risk of blocking the interior of the chilling ring is avoided.

3. The invention is suitable for the water-coal-slurry gasification furnace, and aims to reduce the manufacturing cost and the manufacturing difficulty of the chilling ring for the water-coal-slurry gasification furnace, increase the chilling water flow, optimize the water distribution effect, reduce the risk of the blockage of the chilling ring, prolong the service time of the chilling ring and increase the operation period of the gasification furnace.
