Problems solved by technology

The quenching ring with this structure is divided into two paths, so the cooling speed is slow in the actual process, resulting in damage to the gasifier
The quenching liquid ring gap opened on the outer lip ring of the quenching ring is variable and easy to block, resulting in uneven distribution of the quenching liquid. The working temperature of the chilling ring is too high, which reduces the service life of the chilling ring. At the same time, the high-temperature syngas and molten slag also directly wash the chilling ring, which greatly reduces the service life of the chilling ring

Embodiment Construction

[0011] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0012] A gasifier quench ring, such as figure 1 , 2 As shown, it includes a downcomer 10, an annular outer lip ring 2, an annular inner lip ring 3 and a coolant delivery pipe 6. The annular outer lip ring and the annular inner lip ring form a quench liquid distribution chamber 4, and the annular inner lip ring forms a quenching liquid distribution chamber 4. The lip ring is fixedly connected with the downcomer 10, and the quenching liquid annular gap 7 is formed between the lower part of the annular outer lip ring 2 and the downcomer 10, and it is characterized in that the outside of the quenching liquid distribution chamber 4 is fixedly connected with a cooling liquid The delivery pipe 6, the coolant delivery pipe 6 communicates with the quench liquid distribution chamber 4, the center line of the coolant delivery pipe 6 forms an included angl...

Abstract

The invention discloses a quenching ring for a gasification furnace, with good quenching effect and long service life, comprising a downcomer, an external annular lip ring, an internal annular lip ring and a cooling fluid conveyer pipe. The external annular lip ring and the internal annular lip ring form a quenching liquid distribution room. The internal annular lip ring is fixedly connected with the downcomer. An annular quenching liquid space is formed between the lower part of the external annular lip ring and the downcomer. The external part of the quenching liquid distribution room is fixedly connected with the cooling fluid conveyer pipe which is communicated with the quenching cooling distribution room. The included angle between the centerline of the cooling liquid conveyer pipe and the centerline of the external lip ring and the internal lip ring is 45 degrees and the included angle between the centerline of the cooling liquid conveyer pipe and the quenching liquid distribution room is 45 degrees.

Description

technical field [0001] The invention relates to a quenching ring of a pressurized gasification furnace for coal water slurry or pulverized coal. Background technique [0002] Coal gasification technology is a clean coal technology that can efficiently and cleanly utilize coal. The key equipment of pressurized gasification technology for coal water slurry or pulverized coal is the gasifier, and the coal water slurry or pulverized coal is placed in the combustion chamber of the gasifier Incomplete combustion generates high-temperature synthesis gas at about 1270-1500 °C and molten slag enters the quenching chamber. The key component of the chilling chamber is the chilling ring. The function of the chilling ring is to evenly distribute the chilling liquid on the inner wall of the downcomer to form a water film. The purpose of the chilling ring is to chill the high-temperature syngas and molten slag. , and protect the downcomer from being burned by high-temperature syngas and m...
