Examples:
as shown in fig. 1, a pure oxygen bubbling combustion device comprises bubbling bricks 7 fixed on a wall body 1, wherein the bubbling bricks 7 are connected with bubbling connecting pipes 6 for supplying pure oxygen.
The position of the bubbling brick 7 and the bubbling pipe 6 is shown in fig. 2, the bubbling brick 7 is provided with a through hole, a connecting pipe 74 is arranged in the through hole, and the position of one end of the bubbling pipe 6 extends into the through hole and is connected with the connecting pipe 74 in a threaded manner as shown in fig. 3 and is shown in an enlarged schematic view of a part A of fig. 2. Specifically, a gap is formed between the connection pipe 74 and the inner wall of the through hole, the gap being larger than the wall thickness of the nipple 6 to accommodate the nipple 6. When the bubbling connecting pipe 6 is replaced, the screw thread is unscrewed, so that the replacement is convenient, and the disassembly is convenient. The gap is provided with a sealing ring 10, the inner ring of the end part of the bubbling pipe 6 is an arc-shaped surface, and the end part is abutted against the sealing ring 10.

Pure oxygen sent through the air supply pipeline is flushed out by the bubbling brick 7 after passing through the bubbling connecting pipe 6, so that the soft cushion 12 is sent into the molten salt pool, bubbling is formed in molten salt after the pure oxygen enters the molten salt pool, flowing of the molten salt is disturbed, combustion-supporting organic gas is combusted, and bubbling combustion is realized.
The utility model can effectively improve the treatment efficiency of the organic matters in the waste salt and avoid the residual organic matters in the waste salt (especially the organic matters contained in the waste salt at the lower part of the molten pool).
The pure oxygen bubbling combustion technology has the following advantages:
1. the bubbling devices are distributed at the bottom of the waste salt molten pool, and the gas supply system is used for supplying gas to effectively disturb the liquid molten salt, so that the waste salt is uniformly heated, and organic matters can be decomposed more quickly and completely.
