Description
Technical field
The utility model relates to the dry cleaner industry, refers more particularly to the solvent distilling apparatus in the dry cleaner.
Background technology
Dry cleaner be commonly used to wash those be not suitable for washing with water that machine washing is washed, than the article of higher gears.Generally all dispose the solvent distilling apparatus in traditional dry cleaner, its main application is: after repeatedly washing, cleaning solvent in the dry cleaner---unavoidably can be contaminated as tetrachloro-ethylene, messy, if continue to come laundering of textile fabrics, be certain to cause fabric not wash clean with this dirty cleaning solvent; Therefore, just must carry out the decontamination cleaning to cleaning solvent, the solvent distilling apparatus is exactly the device that is used for cleaning cleaning solvent specially, the structure of traditional solvent distilling apparatus as shown in fig. 1, mainly comprise: distillation case 2, the inside of distillation case 2 is separated into upper and lower two parts, top is distillation zone 3, the bottom is the thermal treatment zone 8, the casing of distillation zone 3 is provided with feed tube 5 and escape pipe 1, feed tube 5 is provided with feed liquor valve 4, and escape pipe 1 is connected with cooler 12, and cooler 12 directly is connected with liquid separator 11; In actual use, generally all heat with steam, thereby also be provided with steam inlet tube 7 and condensed water go out pipe 10 on the casing of the thermal treatment zone 8, steam inlet tube 7 is provided with steam valve 6, and condensed water goes out pipe 10 and is provided with drain valve 9; Above-mentioned cooler 12 generally all uses recirculated cooling water to cool off.The operation principle of above-mentioned distilling apparatus is: put into dirty cleaning solvent in the distillation zone 3 of distillation case 2 by feed tube 5, close feed liquor valve 4 then, in the thermal treatment zone 8, feed steam, cleaning solvent is heated, and make its boiling, consequent washing agent steam enters into cooler 12 by escape pipe 1, in cooler 12, washing agent steam is condensed into drop, and drop flow in the liquid separator 11, finally isolates clean cleaning solvent liquid by liquid separator 11.After distillation work finishes, be left starchy residue solvent in the distillation zone of distillation case, generally just this starchiness residue solvent cleaned out the distillation zone.The shortcoming of doing like this is: owing to also have a certain amount of, available solvent in starchy residue solvent, directly clean out very unfortunately, also caused the waste of cleaning solvent.
Usually in dry cleaner, also dispose solvent recovery unit, its main application is: when being washed after fabric washing finishes, to when being washed fabric drying, reclaim being mingled in the cleaning solvent of being washed in the fabric, to improve the utilization rate of cleaning solvent, cut the waste.The structure of this kind oven dry retracting device as shown in fig. 1, mainly comprise: inner bag shell 13, be provided with washing inner bag 14 in the inner bag shell 13, inner bag shell 13 is connected with a breather line 26, inner bag shell 13 constitutes a gas circulation channel with breather line 26, breather line 26 is provided with air-introduced machine 23, in breather line 26, also be disposed with cooler 25 and heater 24 and 22, be provided with recovery tube 19 below cooler 25, recovery tube 19 directly is connected with liquid separator 11; In actual applications, above-mentioned cooler 25 generally is made of the evaporimeter 25 in the refrigeration unit 21 that is arranged in the dry cleaner, the part that condenser 24 in the refrigeration unit 21 constitutes in the above-mentioned heater, above-mentioned heater also comprise a steam heater 22 of configuration separately.Its operation principle is: when the quilt in the dry cleaner is washed after fabric washing finishes, and the cleaning solvent in the venting dry cleaner washing inner bag 14 at first, and fabric dried, washing inner bag 14 is driven by belt 18 and belt pulley 15 by motor 16; Start air-introduced machine 23 then, and cooler 25 and heater 24 and 22 also started working---promptly: refrigeration unit 21 is started working, also in steam heater 22, feed high-temperature steam; Under the effect of air-introduced machine 23, air in inner bag shell 13 and the washing inner bag 14 enters into breather line 26 by the air inlet place of breather line 26, then again through subcooler 25---promptly: the evaporimeter 25 in the refrigeration unit 21, effect next part air at cooler 25 is condensed into drop, drop constantly splashes in the recovery tube 19, and flow in the liquid separator 11 by recovery tube 19, finally cleaning solvent is separated and reclaim by liquid separator 11; Another part air can continue again forward to flow behind subcooler 25, and through heater---promptly: the condenser 24 in the refrigeration unit 21 and the steam heater 22 of configuration separately, the effect of heater is exactly to add hot-air, air after heater via 24 and 22 heating continue not only to flow and the air outlet place by breather line 26 but get back to inner bag shell 13 and washing inner bag 14 in, the fabric in the inner bag 14 is carried out heating, drying; When hot-air adds heating fabric in inner bag 14, the cleaning solvent gas that will evaporate from fabric is again taken away together, when continuing to flow through cooler 25, can be condensed into drop by some gas again, drop constantly splashes in the recovery tube 19, and flow into again in the liquid separator 11 by recovery tube 19, another part air can continue again to flow forward behind subcooler 25 and through heater 24 and 22; So, gas constantly circulates in breather line 26 and inner bag shell 13 and washing inner bag 14, washed fabric drying the most at last, and most of cleaning solvent that will be mingled in the fabric recycles.Like this, both dry fabric, reclaimed the cleaning solvent in the fabric again, reduced the waste and the loss of cleaning solvent, reduced the washing cost.
Summary of the invention
The purpose of this utility model is: a kind of solvent distilling apparatus that the useable solvents in the starchiness residue in the distillation zone can be carried out recycling is provided.
The main technical principle that the utility model adopts is: when the solvent recovery unit in the dry cleaner at the oven dry fabric and when reclaiming cleaning solvent, hot blast in the breather line is drawn sub-fraction in the distillation zone of distillation case, and allow the air that flows out from the distillation zone be back in the breather line, thereby the useful composition that will remain in the starchiness residual washing-out solvent in the distillation zone reclaims again again.
The concrete technical scheme that the utility model adopts is: the solvent distilling apparatus in the described dry cleaner, mainly comprise: the distillation case, be provided with the distillation zone and the thermal treatment zone in the distillation case, the casing of distillation zone is provided with feed tube and escape pipe, feed tube is provided with the feed liquor valve, escape pipe is connected with cooler, and cooler is connected with the liquid separator; Be characterized in: on the casing of distillation zone, also be provided with blast pipe and discharge pipe, the air outlet place of the breather line in blast pipe and the dry cleaner is connected, the air inlet place of the breather line in discharge pipe and the dry cleaner is connected, blast pipe is provided with the air intake valve, and discharge pipe is provided with out air-valve.
The utility model has the advantages that: use above-mentioned solvent distilling apparatus, dry cleaner is when drying recovery operation, the useful composition that can will remain in the starchiness residual washing-out solvent in the distillation zone reclaims again, can further improve the utilization rate of cleaning solvent, reduces the washing cost.
