PURPOSE:To transfer the slurry circulating liquid in annular pipes successively to the annular pipes of the next stages without causing any trouble by providing the lead-in part nozzle of each connecting pipe to the bent part of the annular pipe into which the circulating liquid descends, in the direction outward of the bent part and below the horizontal line. CONSTITUTION:An annular pipe 1 consists of straight pipes and bends which are communicated into a ring shape and it is erected perpendicularly. The annular pipe 1 of the previous stage and the annular pipe 1' of the next state are connected by means of a connecting pipe 3, whereby a plurality of annular pipes are connected successively into multiple stages. The circulating liquid 4 in the annular pipe 1 is circulated in the arrow direction by a circulating pump 5, and this circulating liquid 4 is transferred to the annular pipe of the next stage through the lead-in part nozzle 3a and lead-out part nozzle 3b of the connecting pipe 3. The mounting direction of the nozzle 3a of the connecting pipe 3 is required to be the direction outward of the bent part and below the horizontal, in the bent part 2, and the direction inclined by 45 deg. in a horizontal direction or circulating flow direction is suitable. |
