Description

Technical Field

[0001] The utility model relates to the technical field of gasification furnace lining, in particular to a quick alignment structure of burner bricks of a gasification furnace. Background Art

[0002] Gasification is a modern high-temperature, high-pressure industrial process that uses coal as raw material. After coal is mixed with high-temperature water vapor and oxygen, a series of chemical reactions occur to convert solid coal into gases containing CO, H2, CH4, etc. It is used to produce chemical products such as synthetic ammonia, methanol and dimethyl ether, as well as direct and indirect liquefaction of coal, combined cycle power generation and multi-generation based on coal gasification. It is an important supporting process in my country's energy and chemical fields.

[0003] The refractory material at the burner of a four-nozzle water-coal slurry gasifier is a weak link in the gasifier. According to the steel shell structure of the gasifier, the refractory bricks can be divided into two parts: channel bricks and furnace bricks. The existing structure of the gasifier burner channel refractory bricks and furnace refractory bricks are two unconnected parts. In the past, during construction, it was necessary to manually pull the center line at the center of the burner channel, and then lay the furnace refractory bricks according to the center line position. In the actual operation process, the refractory bricks in the furnace may have a certain deviation, resulting in it not being on the same center line as the gasifier burner. During operation, the refractory bricks in the burner furnace are unevenly scoured and locally damaged quickly, affecting the service life of the overall burner bricks and increasing labor costs and material costs. Summary of the invention

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a gasification furnace burner brick quick alignment structure, which does not require manual pulling of the center line, ensures that the refractory bricks in the burner furnace and the refractory bricks in the burner channel are aligned in the center, improves construction efficiency, and can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a gasification furnace burner brick quick alignment structure, including burner channel refractory bricks, first burner furnace refractory bricks, second burner furnace refractory bricks and third burner furnace refractory bricks, the burner channel refractory bricks, the first burner furnace refractory bricks, the second burner furnace refractory bricks and the third burner furnace refractory bricks are sequentially spliced ​​by mortise and tenon structures.

[0006] As an optimal technical solution of the utility model, the mortise and tenon joints of the burner channel refractory bricks, the first burner furnace refractory bricks, the second burner furnace refractory bricks and the third burner furnace refractory bricks are all located at the edge of the burner channel and the burner channel composed of the four surfaces is a plane.

[0007] As a preferred technical solution of the utility model, the burner channel refractory bricks and the third burner furnace refractory bricks are L-shaped.

[0008] As a preferred technical solution of the utility model, the refractory bricks in the first burner furnace and the refractory bricks in the second burner furnace are Z-shaped.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows: the gasifier burner brick quick alignment structure is achieved by connecting and laying the burner channel refractory bricks, the first burner furnace refractory bricks, the second burner furnace refractory bricks and the third burner furnace refractory bricks in sequence through mortise and tenon structures, so that the center lines of the burner channel refractory bricks and the furnace refractory bricks coincide with each other. Since the center lines of the burner channel refractory bricks originally coincide with the center lines of the burner channel, the refractory bricks in the furnace and the center of the gasifier burner are aligned, thereby reducing the phenomenon of rapid local damage and extending the overall service life of the burner bricks.
