Abstract
The utility model discloses a kind of ethylene glycol plate heat exchanger exhaust pipes to improve structure, including plate heat exchanger, plate heat exchanger material inlet connects ethylene glycol inlet tube, the material outlet of plate heat exchanger connects ethylene glycol outlet, the ethylene glycol inlet tube of plate heat exchanger also passes through evacuated tube and connects low row general pipeline, exhaust pipe is additionally provided on ethylene glycol outlet, exhaust pipe is connected to by auxiliary exhaust pipe with low row general pipeline.The ethylene glycol plate heat exchanger exhaust pipe, which improves structure, reduces the waste of ethylene glycol and consumption in production of polyester, reduces ethylene glycol effect on environment.
Description
Technical field:
The utility model relates to field of polyester fiber, are especially a kind of ethylene glycol plate heat exchanger exhaust pipe improvement knot
Structure.
Background technique:
Plate heat exchanger is one of ancillary equipment important in polyester process production, and major function is to utilize cooling water and second
Heat is transmitted between two kinds of circulation mediums of glycol, the main circulation medium ethylene glycol that we are needed reduces temperature, to reach me
Technique production requirement.From the point of view of the design scheme of Yuan Zhongfang institute, as shown in Fig. 2, ethylene glycol exports on plate heat exchanger 1
22 position of pipe devises eminence exhaust pipe, and the gas that plate changes interior retention is discharged by opening exhaust pipe 3 when changing filling so as to plate
Body makes ethylene glycol be completely filled with whole platen type heat exchanger 1 and pipeline, and ethylene glycol pipeline will not be occurred by guaranteeing when using stops now
As influencing technique production.But in exhaust process, part ethylene glycol is gone out along exhaust pipe, directly drops onto floor ground
Surface causes some effects to environment, meanwhile, the consumption and waste of ethylene glycol in technique production are also increased for no reason.
Utility model content:
Technical problem to be solved by the utility model is to provide the wastes and consumption of ethylene glycol in a kind of reduction production of polyester
Dosage, the ethylene glycol plate heat exchanger exhaust pipe for reducing ethylene glycol effect on environment improve structure.
The technical solution of the utility model is to provide a kind of ethylene glycol plate heat exchanger exhaust pipe improvement structure, packet
Rubbing board type heat exchanger, plate heat exchanger material inlet connect ethylene glycol inlet tube, and the material outlet of plate heat exchanger connects second two
Alcohol outlet pipe, the ethylene glycol inlet tube of plate heat exchanger also pass through evacuated tube and connect low row general pipeline, also set on ethylene glycol outlet
There is exhaust pipe, exhaust pipe is connected to by auxiliary exhaust pipe with low row general pipeline.
After using the above structure compared with prior art, the utility model, which has the advantage that, passes through auxiliary for exhaust pipe
Exhaust pipe accesses low row general pipeline, and being vented the air being discharged when operation and part ethylene glycol will all be entered by the low row general pipeline of ethylene glycol
Ethylene glycol collecting tank in technique, is recycled by process cycles, it is entirely avoided waste and consumption for no reason, meanwhile, second two
It is directly entered low row general pipeline after alcohol discharge, will not be splashed in external environment, it is entirely avoided ethylene glycol is discharged for environment
Pollution and influence.
Preferably, being respectively equipped with switch valve in exhaust pipe and evacuated tube.
Further, the total pipe end of low row connects ethylene glycol collecting tank.
Detailed description of the invention:
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of the prior art.
Specific embodiment:
The utility model is described in further detail with reference to the accompanying drawings and detailed description:
As shown in Figure 1, a kind of ethylene glycol plate heat exchanger exhaust pipe improves structure, including plate heat exchanger 1, plate-type heat-exchange
The cold medium import of device 1 connects cooling water inlet pipe 24, and the cold medium outlet of plate heat exchanger 1 connects cooling water outlet pipe 23,
1 material inlet of plate heat exchanger connects ethylene glycol inlet tube 21, and the material outlet of plate heat exchanger 1 connects ethylene glycol outlet
22, the ethylene glycol inlet tube 21 of plate heat exchanger 1 also connects low row general pipeline 5 by evacuated tube 6, also sets on ethylene glycol outlet 22
There is exhaust pipe 3, exhaust pipe 3 is connected to by auxiliary exhaust pipe 4 with low row general pipeline 5, and auxiliary exhaust pipe 4 and exhaust pipe 3 are integrally formed,
Exhaust pipe is extended downwardly and is connected to low row general pipeline, low 5 end of row general pipeline is also connect with ethylene glycol collecting tank, is convenient for back
With.Preferably, being respectively equipped with switch valve 7 in exhaust pipe 3 and evacuated tube 6.
Main improvement part is to extend ethylene glycol eminence exhaust pipe and be connected to the low row general pipeline of ethylene glycol, and extension tube caliber is big
Small identical as exhaust pipe, diameter DN20, extending length is about 150cm, will be welded after low row general pipeline's cut, guarantees pipeline and weldering
It stitches closed all right.
Exhaust pipe is accessed into low row general pipeline by auxiliary exhaust pipe, is vented the air being discharged when operation and part ethylene glycol all
The ethylene glycol collecting tank in technique will be entered by the low row general pipeline of ethylene glycol, is recycled by process cycles, it is entirely avoided nothing
The waste and consumption at end, meanwhile, it is directly entered low row general pipeline after ethylene glycol discharge, will not be splashed in external environment, keep away completely
Pollution and influence of the ethylene glycol discharge for environment are exempted from.
Only the utility model preferred embodiment is described above, but is not to be construed as the limit to claim
System.All equivalent structure or equivalent flow shifts done using the utility model specification and accompanying drawing content are included in this
Within the scope of patent protection of utility model.
