Lining plate of pipelining flash-pot

A lining plate of a pipelining flash-pot relates to a pipelining flash-pot structure, in particular to an improved structure of the lining plate of a pipelining flash-pot used for aluminum oxide production, which is characterized in that the lining plate is roughly inverse-T-shaped, and an arc-shaped wing-shaped plate with two ends extending upward is integrated into a whole at the top end of thebasic body of the inverse-T-shaped lining plate. In the lining plate of the pipelining flash-pot provided by the utility model, the two ends on the outer sides of the lining plate extend upward, whichcompletely cover the joint part of the middle lining plate and the edge lining plate, thereby solving the abrasion problem of the joint part.
