Description
Technical field
A kind of chemical fiber wire production equipment field is the utility model is related to, especially a kind of polyester EG circulatory systems.
Background technology
The existing EG circulatory systems generally comprise terminal polymerization kettle, spray condenser, EG collecting tanks, circulating pump, cooling body,
Regulating valve and EG hot wells, terminal polymerization kettle are provided with charging aperture and discharging opening, and spray condenser is connected with the discharging opening on terminal polymerization kettle, spray
Leaching condenser links into an integrated entity with EG collecting tanks, is linked into an integrated entity between EG collecting tanks and EG hot wells by a delivery pipe, and
Circulating pump and gate valve are additionally provided with connecting tube；EG steam in terminal polymerization kettle and oligomer are delivered in spray condenser and carried out
Spray process, when EG steam is sprayed in spray condenser, polyester EG and substantial amounts of oligomer can be produced and together conveyed
To EG collecting tanks, and EG collecting tanks liquid level constantly raises, and at this moment needs to emit unnecessary EG by regulating valve, and
During EG is emitted, oligomer is also discharged away together, but oligomer can be sticked in delivery pipe in discharge process, when
Between it is long, pipeline will be blocked, and so as to can not discharge removing in time, influence normally to produce.
For problem above, it is badly in need of us and solves.
Utility model content
The purpose of this utility model is overcome the deficiencies in the prior art, there is provided one kind ensures that delivery pipe will not be by oligomer
Block, so as to lower the polyester EG circulatory systems of maintenance cost.
In order to achieve the above object, a kind of polyester EG circulatory systems designed by the utility model, it includes terminal polymerization kettle, control
Mechanism, spray condenser, EG collecting tanks, liquid level sensor, circulating pump, regulating valve, EG hot wells, flowmeter, gate valve and EG processed add
Hot tank；Terminal polymerization kettle is provided with charging aperture and discharging opening, and spray condenser is connected with the discharging opening on terminal polymerization kettle, in EG collecting tanks
Inwall is provided with a liquid level sensor, and liquid level sensor transmits a signal to controlling organization, spray condenser and EG collecting tanks
Link into an integrated entity, linked into an integrated entity between EG collecting tanks and EG hot wells by No.1 delivery pipe, and in No.1 connecting tube successively
Provided with circulating pump, gate valve and flowmeter, flowmeter transmits a signal to controlling organization；EG heating tanks are provided with charging aperture and discharging
Mouthful, the discharge outlet on EG heating tanks is connected with No. two connecting tubes, and is connected EG heating tanks with No.1 by No. two connecting tubes
Pipe is linked into an integrated entity, and gate valve, controlling organization control circulating pump, regulating valve and gate valve work are additionally provided with No. two connecting tubes.
In order to which the oligomer that will be preferably blocked on No.1 connection inside pipe wall melts away, one end of No. two connecting tubes and EG
Heating tank is connected, and the other end of No. two connecting tubes is attached with the No.1 connecting tube close to EG collecting tanks one end.
The polyester EG circulatory systems actual use when operation principle be：EG steam in terminal polymerization kettle and oligomer is defeated
Deliver to and spray process is carried out in spray condenser, when EG steam is sprayed in spray condenser, polyester EG and big can be produced
The oligomer of amount is simultaneously together delivered in EG collecting tanks, and when EG collecting tank liquid levels there were not liquid level sensor, liquid level sensor will
Signal is transferred to controlling organization, controlling organization control circulating pump, regulating valve and gate valve work, so that will be unnecessary in EG collecting tanks
Polyester EG is emitted into EG hot wells by No.1 connecting tube, when the flowmeter being arranged in No.1 connecting tube detects that No.1 connects
When the EG flows of outflow are reduced in pipe, controlling organization control EG heating tanks and gate valve work, the EG after heating is delivered to No.1
In connecting tube, so as to which the oligomer being attached in No.1 connecting tube is melted and entered in EG hot wells by the EG of heating,
So as to ensure will not to be blocked the No.1 connecting tube that EG collecting tanks link into an integrated entity with EG hot wells by oligomer.
In accordance with the above, a kind of polyester EG circulatory systems designed by the utility model, are set by unique structure
Meter, the connecting tube for ensureing to link into an integrated entity EG collecting tanks with EG hot wells will not be blocked by oligomer, so as to ensure equipment just
Often operation, reduce the maintenance cost of equipment.Therefore, it has the characteristics that simple in construction, easy to use and reasonable in design.
