Abstract
The utility model relates to chemical fiber wire production equipment field, especially a kind of terminal polymerization kettle circulation EG spray equipment, it comprises EG spray equipment, EG hot well, oligomer cleaning plant and EG circulating pump, and described EG spray equipment, EG hot well, oligomer cleaning plant and EG circulating pump are in turn connected to form the circulatory system by pipeline; EG hot well is directly connected by pipeline with between EG circulating pump simultaneously; Pipeline between EG circulating pump and EG spray equipment is provided with heat exchanger, has been arranged in parallel doubling pipeline at the two ends of heat exchanger, and be provided with control valve on doubling pipeline.This terminal polymerization kettle circulation EG spray equipment, when EG own temperature is lower, can make EG enter EG spray equipment in doubling pipeline, thus reduce the amount of EG through heat exchanger, reduce the fouling in heat exchanger, and the pressure drop that EG can be made to spray reduces, improve spraying effect.
Description
Technical field
The utility model relates to chemical fiber wire production equipment field, especially a kind of terminal polymerization kettle circulation EG spray equipment.
Background technology
When autumn and winter, equitemperature was lower, terminal polymerization kettle circulated sprinkling EG temperature is in below design temperature for a long time, even if but in this case, circulated sprinkling EG still can only walk tubular heat exchanger 1262-H01, due to the continuous fouling in tubular heat exchanger tube side, the circulated sprinkling EG pressure drop entering 1262-H01 is caused to increase gradually, in order to maintain the stable of flow, the frequency and the cleaning 1262-H01 that improve circulated sprinkling EG pump 1262-P01 just become very necessary, this not only wastes electric energy, also add the labour intensity of operative employee.
Utility model content
The purpose of this utility model is deficiency in order to solve above-mentioned technology and provides a kind of structure simple, the terminal polymerization kettle circulation EG spray equipment in the utilization rate that can reduce heat exchanger and the service life of improving heat exchanger.
In order to achieve the above object, terminal polymerization kettle circulation EG spray equipment designed by the utility model, it comprises EG spray equipment, EG hot well, oligomer cleaning plant and EG circulating pump, and described EG spray equipment, EG hot well, oligomer cleaning plant and EG circulating pump are in turn connected to form the circulatory system by pipeline; EG hot well is directly connected by pipeline with between EG circulating pump simultaneously; Pipeline between EG circulating pump and EG spray equipment is provided with heat exchanger, has been arranged in parallel doubling pipeline at the two ends of heat exchanger, and be provided with control valve on doubling pipeline.
Technique scheme, in summer practical process, because the temperature of circulation EG is relatively high, need before entering spray system to lower the temperature to EG, thus adopt heat exchanger to lower the temperature to EG, EG all passes through from heat exchanger inside, but when the autumn and winter, temperature was lower, control valve is opened, impels EG from process in doubling pipeline, reduce the amount of EG from process in heat exchanger, reduce in the fouling of EG in heat exchanger, the serviceability of heat exchanger can be improved, increase the cleaning frequency, increase work efficiency.
As optimization, the structure of described oligomer cleaning plant comprises screw feeder, EG collecting tank and is arranged on the vibratory sieve on EG collecting tank top, be connected by screw feeder between EG collecting tank with EG hot well and transmit EG and oligomer, the oligomer got rid of from screw feeder and EG enter vibratory sieve, and the EG collecting tank of vibratory sieve corresponding position is provided with oligomer outlet.This structure is discharged from bottom due to oligomer and part EG, utilize screw feeder to be promoted to upper end and enter on the vibratory sieve in EG collecting tank, in shaker vibration process, EG enters in EG collecting tank, oligomer is discharged from oligomer outlet simultaneously, realize being separated, simple and convenient, the waste of EG can be reduced in oligomer scale removal process.
Vibratory sieve on described EG collecting tank is obliquely installed, and oligomer outlet is positioned at the lowest part of vibratory sieve.This structure is in shaker vibration process, and the oligomer on vibratory sieve top can move toward lower along vibratory sieve, discharges, excellent result eventually through oligomer outlet.
Described heat exchanger is tubular heat exchanger.This structure heat transfer effect is obvious.
The terminal polymerization kettle circulation EG spray equipment that the utility model obtains, when EG own temperature is lower, EG can be made in doubling pipeline to enter EG spray equipment, thus reduce the amount of EG through heat exchanger, reduce the fouling in heat exchanger, and the pressure drop that EG can be made to spray reduces, improve spraying effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below by embodiment, the utility model will be further described by reference to the accompanying drawings.
Embodiment 1:
