Protecting device of dissolving tank inner wall of alkali recovery furnace

Abstract

The invention discloses a protecting device of a dissolving tank inner wall of a alkali recovery furnace, comprising a alkali recovery furnace dissolving tank (1), and the alkali recovery furnace dissolving tank (1) is provided with a liquid protecting device (2) which can lead the liquid to flow along the dissolving tank inner wall. Through arranging the liquid protecting device at the alkali recovery furnace dissolving tank, the liquid protecting device can lead the whole dissolving tank inner wall to form a liquid protecting curtain from top to bottom; when the chute silencing or liquid melt dissolution and explosion occurs, and partial liquid melt flies toward the inner wall, the liquid melt is firstly contacted with the liquid protecting curtain of the inner wall, thereby avoiding that the high-temperature liquid melt is directly contacted with the dissolving tank inner wall, and the corrosion of the liquid melt to the dissolving tank inner wall of the alkali recovery furnace is effectively prevented; meanwhile, the liquid protecting curtain at the inner wall can wash away the liquid melt to the dissolving tank, and the long-term corrosion caused by bonding of the liquid meltat the dissolving tank inner wall is effectively avoided, and the continuous operation of the device and the safety factor of the device and the operator are increased.

Description

technical field [0001] The invention relates to a protection device for the inner wall of a dissolution tank, in particular to a protection device for the inner wall of a dissolution tank of an alkali recovery furnace. Background technique [0002] In industrial production, the main silencing methods for the molten material in the chute of the alkali recovery furnace are steam, dilute white liquor or water silencing methods. Because the high-temperature molten material is prone to explosion during the process of silencing and dissolving, and the high-temperature molten material has a strong The corrosiveness of the alkali recovery furnace makes the inner wall (especially the front wall) of the dissolution tank of the alkali recovery furnace easily splashed by the melt when the sound is silenced. When the alkali recovery furnace runs for a long time, the inner wall of the dissolution tank will be silenced by the chute or the melt will explode The splashed high-temperature alk...

[0002] In industrial production, the main silencing methods for the molten material in the chute of the alkali recovery furnace are steam, dilute white liquor or water silencing methods. Because the high-temperature molten material is prone to explosion during the process of silencing and dissolving, and the high-temperature molten material has a strong The corrosiveness of the alkali recovery furnace makes the inner wall (especially the front wall) of the dissolution tank of the alkali recovery furnace easily splashed by the melt when the sound is silenced. When the alkali recovery furnace runs for a long time, the inner wall of the dissolution tank will be silenced by the chute or the melt will explode The splashed high-temperature alkali is corroded and damaged, resulting in the leakage of the alkali solution in the dissolution tank, which seriously endangers the safety of equipment and operators. When the damage to the chute of the alkali recovery furnace is serious, the entire alkali recovery furnace will be shut down.
