The invention discloses a pipeline arrangement structure of a
hydrolysis acidification tank, which comprises a plurality of overflow risers arranged in the
hydrolysis acidification tank, overflow outlets are installed on the upper ends of the overflow risers, and the bottom ends of each overflow riser are respectively connected to overflow horizontal pipes, and the overflow The horizontal
pipe extends to the outside of the
hydrolysis and acidification tank, and expansion joints are installed on the overflow horizontal
pipe located outside the hydrolysis and acidification tank, and at least one side of the overflow riser is equipped with an emptying device; the overflow
system only includes several overflow risers and One overflow horizontal
pipe, when emptying, just pull the water outlet end of the emptying device into the overflow port, and it will be discharged from the overflow vertical pipe and overflow horizontal pipe, so the overflow vertical pipe and overflow horizontal pipe are also used as part of the emptying pipeline. The use of pipelines and related
control valves and expansion joints is reduced, and valve wells outside the
pool are omitted. In addition, the
layout of pipelines outside the
pool can be reduced, and the sealing points between the pipeline and the hydrolysis acidification tank are reduced, which simplifies the project and reduces
engineering difficulty.
