Abstract
The utility model discloses a recovery device for ethylene glycol (EG) in a production process of chemical fiber. The recovery device comprises a rack, a recovery drum, a rough filter drum and a fine filter drum, wherein the rough filter drum and the fine filter drum are arranged on the rack. The rough filter drum is provided with a first rough filter mesh and a second rough filter mesh inside, and the second rough filter mesh is arranged under the first rough filter mesh. The aperture of filter holes of the second rough filter mesh is smaller than that of the first rough filter mesh. The fine filter drum is provided with a fine filter mesh inside, and a compression air pipe is connected with the fine filter drum. A reducing valve and an air pressed valve are arranged on the compression air pipe. A middle pipe is connected between the rough filer drum and the fine filter drum, and is provided with a middle valve. The lower portion of the fine filter drum is connected with the recovery drum through a discharging outlet pipe. The recovery device for EG in the production process of the chemical fiber can effectively separate and recover the EG in waste residues, simultaneously saves energy and avoids unnecessary waste.
Description
Technical field
The utility model relates to the retracting device in a kind of production of chemical fibres, the EG retracting device in especially a kind of production of chemical fibres.
Background technology
Along with the progress of society, the chemical fibre industry high speed development, polyester device also emerges in an endless stream.Existing polyester device has common characteristics: the reaction in the polycondensation phase of polyester device is all carried out in vacuum state, between each reactor and vavuum pump, be provided with scraper condenser, after catching, the oligomer cooling that will be carried secretly out in vacuum behind the EG spray by scraper condenser drops in the EG liquid seal trough, in the EG liquid seal trough, be provided with filter plate and filter basket that waste residue filters usefulness, and the later stage vacuum that more arrives reaction requires can be higher, the thing of thereupon carrying secretly must be more, therefore, must be often the filter plate of liquid seal can or the waste residue on the filter basket be cleared up and prevent that filter plate or filter basket from stopping up and cause system's wharf explosion.In cleaning waste slag process in the past, owing to not adopting the waste residue retracting device, therefore the EG in the waste residue can't be carried out the filtered and recycled recycling, caused the serious waste when producing.
Summary of the invention
The purpose of this utility model is design for the deficiency that solves above-mentioned technology a kind of with the EG retracting device in the EG production of chemical fibres that effective separation also reclaims from waste residue.
EG retracting device in the designed production of chemical fibres of the utility model, comprise frame and recycling bin, also comprise the previous cleaning barrel and the smart lauter tub that are arranged on the frame, be provided with the first coarse strainer and the second coarse strainer in the described previous cleaning barrel, described the second coarse strainer is positioned at the first coarse strainer bottom and filter opening aperture less than the first coarse strainer, be provided with in the described smart lauter tub on smart filter screen and the described smart lauter tub and also be connected with compressed air hose, compressed air hose is provided with pressure-reducing valve and presses empty valve; Be connected with intervalve between described previous cleaning barrel and the smart lauter tub, intervalve is provided with intermediate valve, and described smart lauter tub bottom connects recycling bin by discharge nozzle.
As preferably: also comprise controller and liquid-level switch, described liquid-level switch is arranged on the previous cleaning barrel, and described level switch signal inputs to described controller, and described controller is controlled the empty valve of described pressure, and automaticity is higher like this.
During use, pour waste residue and EG mixture into previous cleaning barrel, the first coarse strainer separates oarse-grained waste residue with EG, mixture after the separation is further separated behind the second coarse strainer, thereby the EG that enters in the smart lauter tub is liquid substantially, and then intermediate valve cuts out, opens the empty valve of pressure, smart lauter tub is under the standby state of pressing, in smart lauter tub under the effect of smart filter screen, can be with the suspension among the liquid EG, the filtering of granule waste residue, the EG that enters at last recycling bin can reuse.Wherein, smart lauter tub links to each other with compressed air hose, so that smart lauter tub can have certain pressure, can guarantee the rate of filtration in the situation that smart filter screen mesh is less.
EG retracting device in the production of chemical fibres of the utility model gained, can be with EG effective separation and recovery from waste residue, and this partially recycled EG is in the past can only be processed with waste residue, can greatly save thus the cost in production of polyester, simultaneously also save the energy, avoided unnecessary waste.
Description of drawings
Fig. 1 is embodiment 1 structural representation;
Among the figure: frame 1, recycling bin 2, previous cleaning barrel 3, smart lauter tub 4, the first coarse strainer 5, the second coarse strainer 6, compressed air hose 7, pressure-reducing valve 8, the empty valve 9 of pressure, intervalve 10, intermediate valve 11, discharge nozzle 12, controller 13, liquid-level switch 14, smart filter screen 15.
The specific embodiment
The utility model will be further described by reference to the accompanying drawings below by embodiment.
Embodiment 1:
As shown in Figure 1, EG retracting device in the described production of chemical fibres of the present embodiment, comprise frame 1 and recycling bin 2, also comprise the previous cleaning barrel 3 and the smart lauter tub 4 that are arranged on the frame 1, be provided with the first coarse strainer 5 and the second coarse strainer 6 in the described previous cleaning barrel 3, described the second coarse strainer 6 is positioned at the first coarse strainer 5 bottoms and filter opening aperture less than the first coarse strainer 5, be provided with in the described smart lauter tub 4 on smart filter screen 15 and the described smart lauter tub 4 and also be connected with compressed air hose 7, compressed air hose 7 is provided with pressure-reducing valve 8 and presses empty valve 9; Be connected with intervalve 10 between described previous cleaning barrel 3 and the smart lauter tub 4, intervalve 10 is provided with intermediate valve 11, and described smart lauter tub 4 bottoms connect recycling bin 2 by discharge nozzle 12.Also comprise controller 13 and liquid-level switch 14, described liquid-level switch 14 is arranged on the previous cleaning barrel 3, and described liquid-level switch 14 signals input to described controller 13, the empty valve 9 of the described controller 13 described pressures of control, and automaticity is higher like this.
During use, pour waste residue and EG mixture into previous cleaning barrel 3, the first coarse strainer 5 separates oarse-grained waste residue with EG, mixture after the separation is further separated behind the second coarse strainer 6, thereby the EG that enters in the smart lauter tub 4 is liquid substantially, then intermediate valve 11 cuts out, opens the empty valve 9 of pressure, smart lauter tub 4 is under the standby state of pressing, in smart lauter tub 4 under the effect of smart filter screen 15, can be with the suspension among the liquid EG, the filtering of granule waste residue, the EG that enters at last recycling bin 2 can reuse.Wherein, smart lauter tub 4 links to each other with compressed air hose 7, so that smart lauter tub 4 can have certain pressure, can guarantee the rate of filtration in the situation that smart filter screen 15 mesh are less.The effect of liquid-level switch 14 is: when the EG liquid level reach a certain height in the smart lauter tub 4, it was opened and presses empty valve 9 to controller 13 signal prompts.
