Problems solved by technology

During the operation of the gasifier for more than 50,000 hours, the refractory bricks on the vault were severely scoured. At the end of the operation of the refractory bricks, the wall temperature of the gasifier exceeded the design temperature of the gasifier, posing a threat to the safe operation of the gasifier and affecting the gasification. Furnace benefits

Embodiment Construction

[0012] The present invention will be further described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0013] see image 3 , Figure 4 , the present invention includes a cylinder 1, a vault 2, an expansion joint 3, a conical top 4, a spherical middle part 5, and an inverted conical lower end 6. The expansion joint 3 is set at the connection between the cylinder 1 and the vault 2, so The upper half of the vault 2 is a space enclosed by a conical top 4 and a spherical middle part 5 tangentially, and the lower end near the expansion joint 3 is in an inverted conical shape, and the lower end 6 of the inverted conical shape is opposite to the expansion joint 3 in position. correspond. With this structure, the flow direction of the high-speed airflow is firstly adjusted at the inverted cone transition, avoiding the direct erosion of the expansion joint 3 by the high-speed airflow, meeting the configuration requirements of the airflow fiel...

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 ...
