Abstract

The invention discloses a dome of a coal-water slurry gasifier. The dome includes a conical top and a spherical middle part. The feature is that the lower end of the dome is in an inverted cone shape. The lower end of the vault of the present invention is in an inverted cone shape, so that the vault structure forms a conical, spherical, and inverted cone-shaped space, and the high-speed airflow is first adjusted at the transition of the inverted cone shape, avoiding the direct erosion of the expansion joint by the high-speed airflow , to adapt to the configuration of the air flow field of the gasifier, reduce the erosion of the refractory brick by the air flow field in the furnace, and prolong its service life.

Description

technical field

[0001] The invention relates to the field of a coal-water slurry gasifier device, in particular to a vault of a coal-water slurry gasifier. Background technique

[0002] The multi-nozzle opposed coal-water slurry gasification technology uses process nozzles to atomize the coal-water slurry with high-pressure oxygen and then sprays it into the gasifier for gasification reaction to generate water gas for use in subsequent systems. It is currently being widely used at home and abroad. Promote apps.

[0003] High-temperature-resistant refractory bricks are built inside the multi-nozzle opposed gasifier. The refractory bricks include cylinder 1', vault 2', expansion joint 3', etc., see figure 1 , figure 2 , the original design of the vault 1' is a spherical cone structure, the upper part of the vault 2' is a space enclosed by a cone and a sphere tangentially, the lower end is a straight cylinder, connected with the cylinder 1', and an expansion joint is set at ...
