Embodiment 1

[0032] like figure 1 As shown, a high-temperature gas quenching chamber in this embodiment includes a quenching shell 11 and a water-cooled wall descending cylinder 3. A quenching chamber 12 is formed in the quenching shell 11, and the water-cooled wall descending cylinder 3 is arranged on the quenching shell. In the inner cavity of 11, the upper part of the water-cooled wall descending cylinder 3 is provided with a high-temperature gas inlet 1 for entering high-temperature gas and gasified ash, and the lower part of the water-cooled wall descending cylinder 3 extends into the quenching water bath of the quenching chamber 12, The bottom of the quenching chamber 12 is provided with a slag outlet 5, the upper side wall of the quenching shell is provided with a gas outlet 7, the lower side wall of the quenching chamber 12 is provided with a gray water outlet 6, and the water wall descending tube The annular space between 3 and the quenching shell 11 is the annular space of the qu...

Embodiment 2

[0035] like figure 1 As shown, a high-temperature gas quenching chamber in this embodiment includes all the technical features in Embodiment 1. In addition, it also includes a quenching water inlet 8, which is arranged on the upper part of the quenching shell On the side wall, the chilled water inlet 8 is located below the gas outlet 7.

[0036]A high-temperature gas quenching chamber in this embodiment, high-temperature gas and ash enter the water-cooled wall descending cylinder 3 from the high-temperature gas inlet 1, and enter the water bath at the lower part of the quenching chamber 12 under the protection of the water-cooled wall descending cylinder 3. In the water bath at the lower part of the water wall, the quenching and washing of high-temperature gas is completed, and the temperature of the gas after quenching and washing drops below 300°C, and the gas outlet 7 on the upper part of the quenching chamber 12 goes to the rear section; the quenching water is imported thr...

Embodiment 3

[0039] like figure 1 As shown, a high-temperature gas quenching chamber in this embodiment includes all the technical features in Embodiment 1. In addition, the water-cooled wall descending tube 3 is a vertical tube water-cooled wall or a spiral coil water-cooled wall; the water-cooled The boiler tubes of the wall drop tube 3 are connected by fins or directly connected; it also includes a flow guide tube 4, and the bottom of the water-cooled wall drop tube 3 is connected with a flow guide tube 4; There is a partition 2 between the combustion chamber of the gasifier, the partition 2 is located on the upper part of the annulus of the quenching chamber 12, and the partition 2 is located above the gas outlet 7; the cross section of the water-cooled wall descending tube 3 is circular or polygonal .

[0040] In some optional embodiments, the upper diameter of the water-cooled wall descending tube 3 is not equal to the lower diameter of the water-cooled wall descending tube 3 .

Abstract

The invention discloses a high-temperature coal gas chilling chamber. A chilling chamber is formed in a chilling shell; a water-cooled wall descending cylinder is arranged in an inner cavity of the chilling shell; a high-temperature coal gas inlet for allowing high-temperature coal gas and gasified ash to enter is formed in the upper part of the water-cooled wall descending cylinder; the lower part of the water-cooled wall descending cylinder extends into a chilling water bath of the chilling chamber; a slag discharging port is formed in the bottom of the chilling chamber, a coal gas outlet isformed in the side wall of the upper portion of the chilling shell, an ash water outlet is formed in the side wall of the lower portion of the chilling shell, an annular gap between the water coolingwall descending cylinder and the chilling shell is a chilling chamber annular gap, and a water cooling wall of the water cooling wall descending cylinder is cooled through desalted water. The high-temperature coal gas chilling chamber has the effects that chilling water of a gasification furnace directly enters the chilling chamber through the pipeline, high-temperature coal gas and ash slag arecooled and washed in the chilling chamber, then coal gas containing part of fine ash enters a subsequent procedure to be treated, coarse slag enters a slag discharging system to be treated, and ash water containing fine ash enters the subsequent procedure to be treated.

Description

technical field [0001] The invention relates to the technical field of gasification of carbonaceous substances, in particular to a high-temperature gas quenching chamber, which can be used for high-temperature gasification of carbonaceous substances and gasification ash. Background technique [0002] At present, in the cooling and washing process of high-temperature gas for gasification of carbonaceous substances, chilled water is often used to chill and wash the high-temperature gas and gasification ash. This process is usually carried out in a gasification chilling chamber. The operation stability of the chilling chamber is directly related to the operation stability of the gasification device. [0003] In the quenching chamber of the gasifier, high-temperature coal gas and gasified ash enter from the upper part of the quenching chamber, and need to enter the water bath in the lower part of the quenching chamber through a descending tube. At present, a common practice is t...
