Abstract
The utility model relates to a glycol discharge system with a polyester device vacuum liquid sealing trough. The glycol discharge system comprises the polyester device vacuum liquid sealing trough (1). The discharge system is characterized in that two branch pipelines (4) are led out of the bottom of the polyester device vacuum liquid sealing trough (1), ball valves (47), branch pipeline butterfly valves (41), filters (42), centrifugal pumps (43), pressure meters (44), one-way valves (45) and stop valves (46) are sequentially arranged on the two branch pipelines (4) from front to back, connection pipelines (5) are connected on the two branch pipelines (4) among the ball valves (47) and the branch pipeline butterfly valves (41), and connection pipeline butterfly valves (51) are arranged on the connection pipelines (5). Complicated labor intensity is reduced, energy is saved, environmental pollution is reduced, more importantly, the discharge system is safe, reliable, less in investment, quick in effectiveness, convenient to operate, high in practicability and long in service cycle, and stable operation of a polyester device is effectively guaranteed.
Description
Technical field
The utility model relates to a kind of polyester device vacuum liquid sealing groove ethylene glycol discharge system.
Background technique
referring to Fig. 1, traditional polyester device vacuum liquid sealing groove ethylene glycol discharge system comprises polyester device vacuum liquid sealing groove 1, polyester device vacuum liquid sealing groove 1 bottom is connected with dreg discharging box 2 by pipeline, a main pipe 3 is drawn in polyester device vacuum liquid sealing groove 1 bottom, the front portion of main pipe 3 is provided with main pipe dish valve 31, the middle part of main pipe 3 is divided into two branch pipe(tube)s 4, be disposed with from front to back branch pipe(tube) dish valve 41 on two branch pipe(tube)s 4, filter 42, centrifugal pump 43, pressure gauge 44, one-way valve 45 and stop valve 46, be provided with connecting tube 5 between two branch pipe(tube)s 4 in branch pipe(tube) dish valve 41 the place aheads, be provided with connecting tube dish valve 51 on connecting tube 5, the rear portion of main pipe 3 is connected with ethylene glycol drencher 6.Traditional polyester device vacuum liquid sealing groove ethylene glycol discharge system when the Impurity deposition such as oligomer on tube wall, cause flow to descend, the pipeline buildup is stopped up and the trouble of shutdown that causes, the parking treatment loss is too large, cycle is longer, and labor intensity is high, and brings intractability because pipeline after stopping up exists the dead angle not dismantle when pipe blow-through, all need use hot NaOH buck iterative cycles to boil in the past and wash, also be difficult to dead angle area is processed clean.Therefore, be eager to seek a kind of polyester device vacuum liquid sealing groove ethylene glycol discharge system, can dismantle online to clear up after line clogging and effectively avoid causing trouble of shutdown because of the obstruction of pipeline buildup.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of polyester device vacuum liquid sealing groove ethylene glycol discharge system is provided, and can dismantle online to clear up effectively to avoid stopping up because of the pipeline buildup after line clogging to cause trouble of shutdown.
The purpose of this utility model is achieved in that
a kind of polyester device vacuum liquid sealing groove ethylene glycol discharge system, it comprises polyester device vacuum liquid sealing groove, described polyester device vacuum liquid sealing groove bottom is connected with dreg discharging box by pipeline, two branch pipe(tube)s are drawn in described polyester device vacuum liquid sealing groove bottom, be disposed with from front to back ball valve on described two branch pipe(tube)s, branch pipe(tube) dish valve, filter, centrifugal pump, pressure gauge, one-way valve and stop valve, be connected with connecting tube on two branch pipe(tube)s between described ball valve and branch pipe(tube) dish valve, be provided with connecting tube dish valve on described connecting tube, the rear portion of described main pipe is connected with the ethylene glycol drencher.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is drawn two branch pipe(tube)s bottom polyester device vacuum liquid sealing groove, can use a branch pipe(tube) feed, emptying ethylene glycol after another root branch pipe(tube) is isolated by valve just can be dismantled cleaning, branch pipe(tube) after processing again puts into operation, processes another branch pipe(tube) with same method.The utility model is the operation of steady production device further, avoids stopping up because of the pipeline buildup trouble of shutdown that causes, and simultaneously, has solved the difficult problem because not dismantling online after stopping up.The utility model has reduced complicated labor intensity, has saved the energy, has reduced again environmental pollution; Main is safe and reliable, little investment, instant effect, and easy to operate, practical, life cycle is long, and the stable operation of polyester device is provided a favorable security.
