Abstract

The invention relates to a pipeline system of a second condensation tank. The pipeline system contains a second condensation tank (1) and is characterized in that the lower part of the second condensation tank (1) is provided with a discharge pipeline (2); a return pipeline (3) is connected between the posterior section of the discharge pipeline (2) and a return port of the second condensation tank (1); the posterior section of the discharge pipeline (2) is also connected with a first condensation tank feeding pipeline (4); and two export pumps (2.1) are connected in parallel at the anterior section of the discharge pipeline (2). The pipeline system of the second condensation tank has advantages as follows: failure rate is low; and shut-down and maintenance of a production line are avoided effectively.

Description

technical field [0001] The invention relates to a second condensation tank, in particular to a pipeline system of the second condensation tank, and belongs to the field of chemical equipment. Background technique [0002] During the production of polyester, the material needs to be condensed by the second condensation tank. Once the discharge pipeline of the traditional second condensation tank fails, it needs to be shut down for maintenance, reducing production efficiency. For a large-scale production line, if it needs to be shut down for maintenance, a lot of time is wasted, and a lot of energy is also wasted when the production line is stopped and switched between operations. Therefore, the pipeline system of the second condensation tank with low failure rate and effective avoidance of production line downtime for maintenance is particularly important. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages and...
