Abstract
The utility model relates to a pipeline system of a first condensing drum. The pipeline system of the first condensing drum comprises the first condensing drum (1) and is characterized in that the lower part of the first condensing drum (1) is provided with a first discharging pipeline (2) and a second discharging pipeline (3); a first feeding back pipeline (4) is arranged between the rear segment of the first discharging pipeline (2) and a feeding back port of the first condensing drum (1); the front segment of the first discharging pipeline (2) is in a parallel connection with two first output pumps (2.1) ; a second feeding back pipeline (5) is arranged between the rear segment of the second discharging pipeline (3) and the feeding back port of the first condensing drum (1); the rear segment of the second discharging pipeline (3) is further connected with a feeding back pipeline (6) of a heat medium feeding tank and a charging pipeline (7) of the condensing drum; and the front segment of the second discharging pipeline (3) is in a parallel connection with two second output pumps (3.1). The pipeline system of first condensing drum is advantaged by low failure rate, thereby effectively avoiding shutdown maintenance of a production line.
Description
Technical field
The utility model relates to a kind of the first drainer, relates in particular to a kind of pipe-line system of the first drainer, belongs to the chemical industry equipment field.
Background technology
In producing PET Process, need to carry out condensation to material with the first drainer, once the first traditional drainer discharging pipeline breaks down, need to shut down and keeped in repair, reduce production efficiency.For the maximization production line, if need to shut down, keeped in repair, waste a large amount of time, production line stop and moving between switching also waste mass energy.Therefore less trouble, effectively avoid the pipe-line system of the first drainer of production line stop maintenance particularly important.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, the pipe-line system of the first drainer of provide a kind of less trouble, effectively avoiding production line stop to keep in repair.
The purpose of this utility model is achieved in that
A kind of pipe-line system of the first drainer, it comprises the first drainer, the bottom of described the first drainer is provided with the first discharge pipe and the second discharge pipe, be connected with the first feed back pipeline between the feedback outlet of the back segment of described the first discharge pipe and the first drainer, the leading portion of described the first discharge pipe has been arranged in parallel two the first rear pumps, be connected with the second feed back pipeline between the feedback outlet of the back segment of described the second discharge pipe and the first drainer, the back segment of described the second discharge pipe also is connected with heating agent supplying tank feed back pipeline and drainer feed pipe, the leading portion of described the second discharge pipe has been arranged in parallel two the second rear pumps.
Compared with prior art, the beneficial effects of the utility model are:
The utility model has been arranged in parallel two rear pumps at the leading portion of discharging pipeline; when the leading portion of discharging pipeline has a rear pump to break down; can open another, thereby guarantee that the pipe-line system of the first drainer does not need shutdown to be keeped in repair, and can carry out on-line maintenance.The pipe-line system of this first drainer has advantages of less trouble, effectively avoids production line stop to keep in repair.
The accompanying drawing explanation
The structural representation of the pipe-line system that Fig. 1 is the utility model the first drainer.
Wherein:
The first drainer 1
The first discharge pipe 2, the first rear pump 2.1
The second discharge pipe 3, the second rear pump 3.1
The first feed back pipeline 4
The second feed back pipeline 5
Heating agent supplying tank feed back pipeline 6
Drainer feed pipe 7.
The specific embodiment
Referring to Fig. 1, the pipe-line system of a kind of the first drainer that the utility model relates to, it comprises the first drainer 1, the top of described the first drainer 1 is provided with a plurality of pipelines, described pipeline comprises the heating agent feed pipe, the preheater discharge pipe, the cylindrical shell discharge pipe, esterification heat exchanger discharge pipe and drainer feed back pipeline, the bottom of described the first drainer 1 is provided with the first discharge pipe 2 and the second discharge pipe 3, be connected with the first feed back pipeline 4 between the feedback outlet of the back segment of described the first discharge pipe 2 and the first drainer 1, the leading portion of described the first discharge pipe 2 has been arranged in parallel two the first rear pumps 2.1, be connected with the second feed back pipeline 5 between the feedback outlet of the back segment of described the second discharge pipe 3 and the first drainer 1, the back segment of described the second discharge pipe 3 also is connected with heating agent supplying tank feed back pipeline 6 and drainer feed pipe 7, the leading portion of described the second discharge pipe 3 has been arranged in parallel two the second rear pumps 3.1.
