Definitions

  • This invention relates to a method for treating fibrous material, in which the material is treated on a foraminate conveyor belt with water, with a hydrocarbon solvent with strong 4extracting power, and with a tierce solvent which mixes partly with water and partly with the hydrocarbon solvent.
  • This previous method pertains particularly to the treatment of wool, while the present invention relates to the treatment of fibrous materials in general and thus among others to the treatment of Wool.
  • the material to be treated is-sprinkled in defined zones, separately with water, with a tierce solvent that mixes partly with Water and partly with a hydrocarbon solvent, and nally with this hydrocarbon solvent.
  • the purpose is to provide avmethod which is simpler and reduced to two steps of treatment.
  • the invention has for its object to provide a method which may be worked by means of an uncomplex installation.
  • the invention has also for its object to provide a method that insures aA fast and deep application of the various liquids used.
  • the treatment is essentially made in two zones, the liquids which have passed through the material being collected in the same decanting tank, the lower phase being returned at least partly over the material in the rst zone, the upper phase bein-g returned at least partially above the second zone.
  • the material is treated in the second zone with the upper phase in counter-current combined with closed-circuit circulations.
  • the invention also relates to an installation for working the above method.
  • the invention relates to an installation ⁇ for treating brous materials whichl comprises a foraminate conveying belt, sprinklers above the conveyor and a decanting tank underneath the conveyor.
  • the invention according to the present application however enables a complete treatment of the brous material by means of the liquids collected in the decanting tank the phases of these liquids being discharged only to recover materials which -have been extracted from the wool.
  • sprinklers above a first zone of the conveyor are connected to a sucking opening which is ice located in the lower part of the tank, while sprinklers above a second zone of the conveyor are connected to a sucking opening in the upper part of the tank.
  • the installation comprises a decanting tank which is divided into compartments by partitions that form overflows and which extend to some distance from the bottom so as to have a passage between the bottom and each partition.
  • each compartment is provided with a sucking opening which is located in the upper part theerof and which is connected, through a pump and a pipe, to at least one sprinkler which is provided above the collecting vessel which supplies .this same compartment.
  • FIG- URES la and lb shows diagrammatically an installation for treating brous material according to the invention.
  • the invention shown in the figure comprises an endless conveyor with foraminate belt 1, which is guided at the ends by two drums (not shown), one of said drums only ,guiding the conveyor while the other one guides and drives said conveyor.
  • the sprinkler 3 In the feeding ⁇ direction of the wool, the sprinkler 3 is followed by sprinklers 6 the output of which is regulated by valve 7 and to which is supplied liquid forced by a pump 8 into the outlet pipe 9 thereof.
  • the pump 8 sucks through a pipe 10, which is connected in turn to a sucking opening 11, the lower phase that forms in the decanting tank 12.
  • the various liquids which have passed through the wool are nally collected through collecting vessels 13 and pipes 14, into one and the same decanting tank 12.
  • These liquids are essentially comprised of the aqueous alcohol solution which is supplied by the pipes 2 and 15 and of a solution which is rich in hexane and which is introduced into the installation through the pipe 16.
  • the upper phase is thus hexane-rich and poor in isopropyl alcohol; due to this phase containing practically hexane, it does form a micella rich in grease.
  • This upper phase is designated by reference 17.
  • the lower phase 18 is an aqueous alcohol solution and comprises essentially the salts and notably those potassium salts which are Water-soluble.
  • An intermediate layer 19 comprises notably the mucilages and forms a defined separation between the clear upper phase, hexane-rich, and the muddy lower phase, which is essentially comprised of an aqueous alcohol solution.
  • a dragging chain 20, guided by the drums 21, is driven along the direction of arrows 22.
  • the bottom of the decanting tank 12 is provided with a slanting part 23 the upwards gradient of which corresponds to the feeding direction of the lower side of the dragging chain 20.
  • the sands and other solid materials comprised in the lower phase 18 are taken along by the chain 20 and fall into the pipe 24 which discharges them from the installation.
  • the sprinklers 6 are followed by a sprinkler 25 which is supplied by the pipe 15, a valve 26 regulating the liquid flow rate through the sprinkler 25.
  • the pipe supplies through the sprinkler an alcohol-richsolution. Water and alcohol are thus introduced in the installation through the pipes 2 and 15.
  • the sprinkler 25 is followed by two pressing rollers 27, one of which lies underneath and the other one above the upper side of the conveyor; the wool is thus freed from the larger part of the liquid by passing through the pressing rollers 27.
  • the wool then passes below a series of sprinklers 28.
  • Each sprinkler 28 is connected by a pipe 29 to the outlet of a pump 30.
  • Each one of the pumps 30 is supplied with the upper phase 17 of the liquids collected in the decanting tank 12 through a sucking opening 31 and a sucking pipe 32.
  • a valve 33 arranged in pipe 29 allows to regulate the output.
  • the sucking openings 31 are located in the upper part of the tank 12 somewhat below the level which is normally reached by the liquids in the tank.
  • the sprinklers 28 thus bring the upper phase 17 formed in the decanting tank 12 above the wool.
  • the wool is thus sprinkled with a hexane-rich micella.
  • the decanting tank 12 is divided in various compartments by partitions 34.
  • the height of these partitions is such as to allow the overflowing from one compartment to another.
  • these partitions 34 do not reach down to the bottom 35 of the decanting tank 12.
  • the lower phase 18, formed in the decanting tank 12 may thus pass from one compartment to another without being constricted by the partitions 34; the space left free between the lower edge of the partitions 34 and the bottom 35 of the decanting tank 12 is also necessary to let the lower side of the dragging chain 20 pass through.
  • the various partitions 34 are provided with an ejector 36 at the level of the intermediate layer 19 which separates the upper phase 17 from the lower phase 18.
  • the ejectors 36 are thus essentially provided to advance the intermediate layer 19 along the feeding direction of the lower side of the dragging chain 20.
  • Each ejector 36 is connected by a pipe 37 in which is arranged a valve 38, to a pipe 29 which is supplied by a sucking opening 31 located on the opposite side of the partition 34. Opening of the valve 38 t'nus causes advancing of the intermediate layer 19 along the feeding direction of the lower side of the dragging chain 20 by means of a liquid stream which is comprised of the upper phase 17, said liquid however entering the same compartment wherefrom it was sucked by the sucking opening 31.
  • the ejectors 36 thus do not inuence in principle the movement oi the upper phase from one compartment to another of the decanting tank.
  • a partition 39 separates the last one of the compartments connected through a sucking opening 31, pipes 32 and 29 and a pump 30, to a sprinkler 28, from a compartment 40 which is located on the discharge side of the conveyor 1.
  • the compartment 40 is supplied with the lower phase from the compartment adjacent the loading side, through the' opening 41 which is left free between the' bottom 35 of the tank 12 and the partition 39.
  • the compartment 40 vis supplied with hexane-rich solution by the pipe 16 through an ejector 42 which supplies at the same time the compartment 40 with the intermediate layer from said adjacent compartment.
  • a valve 43 regulates the liquid ow rate supplied by the pipe 16 through the ejector 42 into the compartment 40.
  • the liquid supplied through the pipe 16 comes from a refining and distilling installation which comprises a unit with the installation shown.
  • the compartment 40 thus receiving a hexane-rich solution, as well as the components of the lower'phase and of the intermediate layer of the preceding compartments of the decanting tank, in this compartment is formed a lower phase 45, an intermediate layer 46 and an upper phase 44.
  • a sucking opening 47, a pipe 48, a pump 49 and a pipe 50 bring the upper phase formed in the compartment 40 into the adjacent compartment which is located on the loading side of the conveyor.
  • This last compartment thus receives in the upper part thereof a hexane-rich solution which comprises about 13% alcohol, but which is nearly substantially free of grease and other materials to be extracted from the wool.
  • the sucking opening 31 of this compartment brings this upper phase above the wool lwhich lies above that collecting' vessel 13 which is nearest the discharge side of the conveyor.
  • Circulating of the kupper phase with a large ow is thus produced for each one of the compartments 51 to 56, while at the same time there is produced a somewhat more restricted flow from the compartment 51 towards compartment 56 through compartments 52 to 55.
  • Each series of sprinklers 28 supplied from the same compartment is followed by pressing rollers 27, in such a way that the wool be freed from the largest part of the liquid thereof before passing to the zone covered by the sprinklers 28 nearer the discharge side of the conveyor.
  • pressing rollers 27 are also provided between the sprinkler 25 and the sprinklers 28 that correspond to compartment 56.
  • the wool fed to the upper side of the ⁇ conveyor 1 is thus sprinkled by the sprinklers 3, 6 and 25 with an aqueous alcohol solution which is comprised at least partly of the lower phase which forms in the decanting tank 12. Thereafter, the wool is sprinkled with a hexane-rich solution which is comprised of the upper phase formed in the decanting tank.
  • the intermediate layer 46 and the lower phase 45 of the compartment 40 are discharged through the pipes 57 and 58 to an installation for distilling the muds for-med by this lower phase 45 and this intermediate layer 46.
  • the pipe 57 is connected to a sucking opening 59 that lies at the level of the intermediate layer 46
  • the pipe 58 is connected to a sucking opening 60 which is located at the level of the lower phase 45.
  • a valve 61 is arranged in the pipe 57 and a valve 62 in the pipe 58.
  • the lower part of the decanting tank 12 also communi- Cates by an opening 63 with a compartment 64 which is separated from the tank proper by the partition 65- and serves as florentine.
  • the opening 63 is located in the lower part of the tank 12 and of the compartment 64, in such a way that only the lower phase 18 may enter the compartment 64 through the opening 63.
  • the compartment ⁇ 64 overflows into the pipe 66 which leads to the installation for distilling the muds, mentioned above.
  • a valve 67 allows to regulate said discharge.
  • the grease-rich micella comprised of the upper phase from the compartment 56 is sucked through the sucking opening 68 which leads by a pipe 69, in which is arranged a valve 70, towards an installation for distilling micella.
  • part of the liquid supplied by the pipe 69 may be returned through the pipe 71 into the compartment 51.
  • a valve 72 allows to regulate the rich micella flow which is sent towards the compartment 51 of the decanting tank 12, while an output-meter 73 ⁇ enables to control this flow.
  • This recycling of rich micella adds grease to the micella of the compartment 51 which is sent on the wool on the discharge side, in such a way that the amount of grease in the wool is adjustable. Indeed, the cleaning of the wool by means of the micella as described above would normally give a wool which is too poor in grease and consequently a frangible fiber. This drawback is avoided by making the micella richer in the last compartment.
  • the wool is essentially treated in a rst zone with an aqueous alcohol solution and in a second zone with a hexane-rich solution.
  • the sprinklers 3, 6 and 25 determine the Iirst zone.
  • the sprinklers 28 determine the second zone.
  • the upper side of the conveyor 1 passes through zones 'for evaporating the solvent, for eliminating the solvent gases and for conditioning, as already known from the above U.S. patent.
  • Method for treating brous material in which the material is treated on a forarninate conveyor belt with water, with a hydrocarbon solvent with stron-g extracting power, and with a tierce solvent which mixes partly with water and partly with the hydrocarbon sol-vent, which further comprises making the treatment essentially in two zones, the liquids which have passed through the material being collected in the same decanting tank, the lower phase being returned at least partly over the material in the -rst zone, the upper phase being returned at least partially above the second zone.
