Abstract
The invention relates to a pipeline system of a blow-down gathering tank. The pipeline system comprises a blow-down gathering tank (1) and is characterized in that the upper part of the blow-down gathering tank (1) is connected with a gas-liquid separation tank (6); the upper part of the blow-down gathering tank (1) is also connected with a heat medium feeding pipeline (5); a discharge port of the blow-down gathering tank (1) is provided with a discharge pipeline (2) which is equipped with export pumps (2.1); there are two export pumps which are connected in parallel; the rear end of the discharge pipeline (2) is connected in parallel with a condensation tank feeding pipeline (3) and a blow-down gathering tank return pipeline (4); and the rear end of the blow-down gathering tank return pipeline (4) is connected with a return port of the blow-down gathering tank (1). The pipeline system of the blow-down gathering tank has advantages as follows: failure rate is low; and shutdown and maintenance of a production line are avoided effectively.
Description
Technical field
The present invention relates to a kind of emptying collecting tank, particularly relate to a kind of pipe-line system of emptying collecting tank, belong to field of chemical equipment.
Background technology
In production PET Process, need to use emptying collecting tank, traditional emptying collecting tank discharging pipeline, once break down, needs shutdown to keep in repair, and reduces production efficiency.For maximization production line, if need shutdown to keep in repair, waste a large amount of time, the switching between the stopping of production line and operation also wastes mass energy.Therefore less trouble, effectively avoid production line stop to keep in repair the pipe-line system of emptying collecting tank particularly important.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, the pipe-line system of emptying collecting tank provide a kind of less trouble, effectively avoiding production line stop to keep in repair.
The object of the present invention is achieved like this:
A kind of pipe-line system of emptying collecting tank, it comprises emptying collecting tank, the top of described emptying collecting tank is connected with knockout drum, the top of described emptying collecting tank is also connected with heating agent feed pipe, the discharging opening of described emptying collecting tank is provided with discharge pipe, described discharge pipe is provided with rear pump, described rear pump has been arranged in parallel two, the rear end of described discharge pipe is connected in parallel to cold drainer feeding pipeline and emptying collecting tank feed back pipeline, the rear end of described cold drainer feeding pipeline is connected with the charging aperture of cold drainer, the rear end of described emptying collecting tank feed back pipeline is connected with the feedback outlet of emptying collecting tank.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention has been arranged in parallel two rear pumps at discharging pipeline, when discharging pipeline has a rear pump to break down, can open another, thus ensures that the pipe-line system of emptying collecting tank does not need shutdown to keep in repair, and can carry out on-line maintenance.The advantage that the pipe-line system of this emptying collecting tank has less trouble, effectively avoids production line stop to keep in repair.
Accompanying drawing explanation
Fig. 1 is the structural representation of the pipe-line system of emptying collecting tank of the present invention.
Wherein:
Emptying collecting tank 1
Discharge pipe 2, rear pump 2.1
Cold drainer feeding pipeline 3
Emptying collecting tank feed back pipeline 4
Heating agent feed pipe 5
Knockout drum 6.
Detailed description of the invention
See Fig. 1, the pipe-line system of a kind of emptying collecting tank that the present invention relates to, it comprises emptying collecting tank 1, the top of described emptying collecting tank 1 is connected with knockout drum 6, the top of described emptying collecting tank 1 is also connected with heating agent feed pipe 5, the discharging opening of described emptying collecting tank 1 is provided with discharge pipe 2, described discharge pipe 2 is provided with rear pump 2.1, described rear pump 2.1 has been arranged in parallel two, the rear end of described discharge pipe 2 is connected in parallel to cold drainer feeding pipeline 3 and emptying collecting tank feed back pipeline 4, the rear end of described cold drainer feeding pipeline 3 is connected with the charging aperture of cold drainer, the rear end of described emptying collecting tank feed back pipeline 4 is connected with the feedback outlet of emptying collecting tank 1.
