Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of gasification furnace quenching chamber, concretely to a gasification furnace quenching chamber. BACKGROUND

[0002] The gasification furnace quenching chamber is an important component of the gasification furnace system. The temperature of the synthesis gas from the combustion chamber of the gasification furnace is usually very high, generally around 1400 DEG C. The quenching chamber sprays quenching water into the high-temperature synthesis gas, so that the synthesis gas directly contacts with the quenching water. The synthesis gas is rapidly cooled to a temperature range that can be handled by the subsequent process by using the heat absorption of water evaporation, generally to about 300 DEG C. This process not only protects the subsequent equipment and avoids damage due to high temperature, but also ensures that the synthesis gas is purified and processed at a suitable temperature. In the gasification process, the ash in the raw coal exists in the form of molten slag at high temperature, and some solid particles and dust are also carried in the synthesis gas. When the high-temperature synthesis gas enters the quenching chamber and contacts with the quenching water, the molten slag and dust are cooled and solidified by the quenching water. Part of the particles will settle at the bottom of the quenching chamber due to gravity and be discharged with the black water. Another part of the fine particles will be adsorbed by the water film or carried away with the water flow, thereby realizing the preliminary purification of the synthesis gas and reducing the load and wear of the subsequent purification equipment.

[0003] The Chinese patent with publication number CN211079061U discloses a gasification furnace quenching chamber with a flow guide cylinder. The quenching chamber includes a shell, a downcomer arranged inside the shell, a flow guide cylinder coaxially sleeved outside the downcomer, and an annular gap formed between the flow guide cylinder and the downcomer. One end of the downcomer is connected to a gasification furnace, and the other end is provided with a gas distribution device in the form of a conical section that is butted against the outer edge of the downcomer. The conical section is provided with gas holes. The utility model forms liquid circulation by setting the flow guide cylinder to prevent fine coal ash particles from depositing and effectively solve the problem of blockage caused by fine particles. By setting the gas distribution device, small bubbles can be effectively formed, the interfacial area of the bubbles is increased, and the effect of water bath humidification, dust removal, ash removal and cooling is greatly improved, thereby reducing the amount of coal ash carried by the synthesis gas into the next process.

[0004] Although the above-mentioned patent can prevent fine coal ash particles from depositing, it is not convenient for automatic and rapid cleaning of impurity particles in the gasification furnace quenching chamber. The particles can only be carried away by water, which can cause certain particle residues in the quenching chamber. Moreover, the water spray of the quenching ring in the quenching chamber disclosed in the above-mentioned patent cannot be adjusted in angle, which leads to a small coverage range and is not conducive to the full contact between the quenching water and the synthesis gas.
