Abstract
The invention belongs to the field of chemical fibre production equipment, and especially relates to a polyester stable EG adding device. The polyester stable EG adding device comprises a fresh EG tank and a fresh EG pump; the fresh EG tank is connected with the fresh EG pump via a pipeline; the fresh EG pump is connected with a spraying system and an EG outlet via pipelines respectively; the pipeline between the fresh EG pump and the EG outlet is provided with a sluice valve, a check valve, and a low thermal pressure alarm switch successively from the fresh EG pump to the EG outlet; and a pipeline is arranged between the fresh EG pump and the EG outlet via parallel connection, and the pipeline is provided with a stable EG tank, a stable EG pump, and a control valve successively. According to the polyester stable EG adding device, the polyester stable EG adding device is provided with the stable EG tank and the stable EG pump, so that when output pressure is not high enough, the stable EG pump can be used for auxiliary conveying, and conveying stability is ensured; and at normal working conditions, electricity consumption is reduced, and energy is saved.
Description
Technical field
The present invention relates to field of chemical fiber production equipment, especially a kind of stable polyester EG adding set.
Background technology
In existing polyester device, the effect of stablizing EG is most important, and strengthening esterification while it ensures the mobility of material in pipeline, is indispensable a kind of pipeline auxiliary material additive in Du Pont's device polyester process.Existing EG directly inputs spray equipment and delivery port by fresh EG pump, if this system in use breaks down, then system can be caused out of service, causes to produce to interrupt.
Summary of the invention
The object of the invention is the deficiency in order to solve above-mentioned technology and provide a kind of structure simple, the stable polyester EG adding set that operation stability is high.
In order to achieve the above object, stable polyester EG adding set designed by the present invention, it comprises fresh EG tank, fresh EG pump, fresh EG tank connects fresh EG pump by pipeline, fresh EG pump is connected with sprinkling system and EG delivery port respectively by pipeline, and the pipeline between fresh EG pump and EG delivery port is disposed with gate valve, vacuum breaker, the low report switch of thermal pressure by fresh EG pump to EG delivery port direction; Between fresh EG pump and EG delivery port, be parallel with a pipeline, this pipeline be disposed with stable EG tank, stablize EG pump and control valve.
In technique scheme, fresh EG pump is utilized EG to be delivered to sprinkling system and EG delivery port, and when EG normally carried by new E G pump, the display of thermal pressure low report switch is normal, then system worked well, and when the low report switch alarm of thermal pressure, then the output flow representing EG delivery port is not enough, now stablize EG pump startup, control valve opens, then utilize and stablize the flow that EG pump output EG supplements EG delivery port; To ensure that the flow of EG delivery port remains stable.
As optimization, be arranged in parallel EG pump for subsequent use at the two ends of fresh EG pump.When fresh EG pump breaks down, EG pump for subsequent use can be used to replace, ensure the normal operation of equipment, avoid the situation of shutting down.
The stable polyester EG adding set that the present invention obtains, utilizes the setting of stablizing EG tank and stable EG pump, when the pressure exported is inadequate, stable EG pump can be utilized to carry out auxiliary conveying, guarantee the stability of carrying; And can electric quantity consumption be reduced in normal operating conditions, save energy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below by embodiment, the invention will be further described by reference to the accompanying drawings.
Embodiment 1:
As shown in Figure 1, the stable polyester EG adding set that the present embodiment describes, it comprises fresh EG tank 1, fresh EG pump 2, fresh EG tank 1 connects fresh EG pump 2 by pipeline, fresh EG pump 2 is connected with sprinkling system 3 and EG delivery port 4 respectively by pipeline, and the pipeline between fresh EG pump 2 and EG delivery port 4 is disposed with gate valve 8, vacuum breaker 9, the low report switch 10 of thermal pressure by fresh EG pump 2 to EG delivery port 4 direction; Between fresh EG pump 2 and EG delivery port 4, be parallel with a pipeline, this pipeline is disposed with stable EG tank 5, stablize EG pump 6 and control valve 7; EG pump 11 for subsequent use has been arranged in parallel at the two ends of fresh EG pump 2.
