Description
Technical field
It the utility model is related to experimental branch line equipment technical field, the polyester oligomer in especially a kind of ethylene glycol is removed
Device.
Background technology
In existing polyester device, the effect of 1252-T03 capture pots is most important, and it, which is primarily served, catches 1252-
The bulk reacting oligomer that T01 hot wells are extracted out from spray condenser 1252-S01（That is oligomer caused by prepolymerization reaction）.And
The 1252-T03 of existing apparatus needs periodic cleaning（About every 5 days once）, it is necessary to enter to 1252-T03 in scale removal process
Row emptying, if during emptying, having bulk oligomer to fall in pipeline, discharge pipe line blocking will be caused, it is necessary to clear up pipeline.
The cleaning pipeline consuming time is longer, substantially reduces operating efficiency.And discharge process bulk oligomer is more, blocking phenomenon takes place frequently.
Utility model content
The purpose of this utility model be in order to solve the deficiency of above-mentioned technology and provide it is a kind of simple in construction, can be by hot well
Polyester oligomer remove and the polyester oligomer remove device in the ethylene glycol that is resulted in blockage to pipeline can be avoided.
In order to achieve the above object, the polyester oligomer remove device in a kind of ethylene glycol designed by the utility model,
It includes prepolymerization kettle, spray condenser, hot well, capture pot and overflow launder；Wherein prepolymerization kettle is connected to spray condenser, is spraying
The bottom of condenser is provided with efferent duct, and efferent duct stretches into the middle lower end of hot well, and is provided between hot well and spray condenser
Circulating line；The lower end of hot well is connected in capture pot by pipeline, and one is provided with the pipeline between hot well and capture pot
Number valve, is connected by pipeline between described capture pot and overflow launder, is set on the pipeline between overflow launder and capture pot
One filter, No. two valves are set on the pipeline between filter and capture pot.
It is close to each other between described filter and capture pot.
Above-mentioned technical proposal, during the ethylene glycol in hot well carries out spraying cooling, No.1 valve is opened, then is sprayed
During caused polyester oligomer can be deposited on by pipeline in capture pot, after certain time, capture pot need cleaning when,
No.1 valve is then closed, opens No. two valves, now, the ethylene glycol in capture pot can enter overflow launder by pipeline, and second two
The small-sized polyester oligomer in part can be driven to enter pipeline in alcohol flow process, but can be intercepted by filter, so as to cause
The situation that follow-up most pipeline and overflow launder block, it is only necessary to after the polyester oligomer cleaning in capture pot, together
When filter is cleared up, it is simple and convenient, can greatly improve operating efficiency.
The polyester oligomer remove device in a kind of ethylene glycol obtained by the utility model, can by the setting of filter
Polyester oligomer during capture pot discharge ethylene glycol is collected in the filter, filter is also clear when clearing up capture pot every time
Reason once, can effectively avoid pipeline from situation about blocking occur, greatly improve operating efficiency, labor intensity is low.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below by embodiment combination accompanying drawing, the utility model will be further described.
Embodiment 1：
As shown in figure 1, the polyester oligomer remove device in a kind of ethylene glycol of the present embodiment description, it includes prepolymerization kettle
1st, spray condenser 2, hot well 3, capture pot 4 and overflow launder 5；Wherein prepolymerization kettle 1 is connected to spray condenser 2, is condensed in spray
The bottom of device 2 is provided with efferent duct 6, and efferent duct 6 stretches into the middle lower end of hot well 3, and is set between hot well 3 and spray condenser 2
There is circulating line 7；The lower end of hot well 3 is connected in capture pot 4 by pipeline, is set on the pipeline between hot well 3 and capture pot 4
No.1 valve 8 is equipped with, is connected between described capture pot 4 and overflow launder 5 by pipeline, between overflow launder 5 and capture pot 4
One filter 10 is set on pipeline, No. two valves 9 are set on the pipeline between filter 10 and capture pot 4.Described mistake
Close to each other between filter 10 and capture pot 4, i.e., the pipeline between capture pot 4 and filter 10 is short as far as possible.
Claims (2)
