Following further technical characterictic is that the present invention is exclusive:

The immersion depth of first liquid bath approximates the total length of wool in the grease fiber greatly, and for pure Mai Linuo wool, its depth bounds is the 75-105 millimeter.The belt speed of conveyer belt be 2-4 rice/minute; One is used to make liquid bath pond liquid level to be in the induction system of specifying immersion depth in first and second liquid baths; The intensity of load of conveyer belt is 2-3 kilogram/rice ²; The speed that solvent flows altogether makes it to have and the identical speed of conveying belt speed for promoting wool, and pressure is 100 pounds/inch ²; Jet speed is 50-100 at first liquid bath in the spray equipment, and 000 liter/hour, promptly being in to get on from the wool that soaks does not disarray the flow velocity of wool again except that grease and dirt; The conveyer belt of first and second liquid baths is a mesh-type, has 2 millimeters to 4 millimeters square hole so that allow solvent can see through conveyer belt; (for obtaining optimum, should be able to guarantee to remove to greatest extent dirt and grease on the wool by ejection of solvent and conveyer belt to the sharp liquid surface fluctuation that spatters generation of solvent, and not disarray wool.To those skilled in the art advantageously, the carrying material of conveyer belt, belt speed reaches flow velocity degree altogether, expulsion pressure and jet velocity can be adjusted with the wool that adapts to various different qualities and other animal fiber); The flow velocity that comes down in torrents of per hour handling first liquid bath of 750 kilograms of wools in the grease is 5000 liters/hour (in fact the speed of coming down in torrents with the distillation speed of distiller and second liquid bath is identical); In fact the second liquid bath speed equate with the first liquid bath speed; The filter that being used in second liquid bath further removed fine particle also can be used for residual dirt of filtering and sunit (soluble-salt of wool perspiration glandular secretion); This filter is the solvent cleaning as much as possible to guarantee to spray out between solvent liquid bath and spray equipment; Same filter also is arranged between the liquid bath (pond) and spray equipment thereof of first liquid bath.

To in conjunction with the accompanying drawings wool processed equipment and technology be described in detail by embodiments of the invention below.

Fig. 1 is the generalized section of wool processed equipment according to an embodiment of the invention;

Fig. 2 is the schematic flow sheet of the wool processed technology that proposes of the present invention.

Referring to accompanying drawing, in this embodiment of the invention, a kind of wool processed equipment 1 as shown in Figure 1, includes inlet roller 2, enters first liquid bath 3 by the wool in conveyer belt carrying access arrangement for example through this inlet roller 2.The liquid level of the solvent in first liquid bath 3 and second liquid bath 4 dots in the figure.Liquid bath 3 and 4 is separated by dividing plate 12.The solvent that is used as the wetting agent part in the liquid bath 3 is transported in the outlet 11 by pipeline, and after the wool that enters had just been crossed roller 2, they were transported in the liquid bath 3 again to soak these wools.The wool that soaked is like this fallen on the belt surface of the conveyer belt 5 in first liquid bath 3 then, and is being carried by conveyer belt 5 with certain speed and to advance.Another part solvent in the liquid bath 3 is sent to outlet 14, pressurized flows into the fall region that wool in the liquid bath 3 is fallen conveyer belt 5 then, thisly is used to guarantee to have the speed identical with the speed of service of conveyer belt with the wool that conveyer belt 5 is advanced by exporting the 14 common streams that flow out.Another part solvent in the liquid bath 3 passes a filter (not shown) and is transported in the spray equipment 7, and thus, this partial solvent pressurized sprays downwards and mixes to remove grease and the dirt of carrying on the wool on the conveyer belt 5 with solvent 13.Conveyer belt 5 and top contained wool thereof are elevated out the liquid level of solvent 13 between roller 16 and 17, and in this zone, and the solvent 13 that transports from second liquid bath 4 is crossed dike bank 8 flushing wools with grease and the dirt of further removing on it.

The wool that washed like this continues to transmit on conveyer belt 5, after it crosses roller 17, falls on the conveyer belt 6 in second liquid bath 4.Partial solvent 13 in second liquid bath 4 flows solvent altogether by nozzle 15 conducts.A part of in addition solvent is sent to spray equipment 9 through a filter (not shown), thus, this partial solvent pressurized sprays downwards, mixes with the solvent 13 that is positioned at conveyer belt 6 zones with further removal to be stated from grease and dirt on the wool on the conveyer belt 6.The part of the conveyer belt 6 between roller 18 and 19 is lifted on the liquid level of solvent 13 in second liquid bath 4, carrying also is positioned at the wool on this part more than the horizontal liquid level of solvent 13 of second liquid bath 4, and is washed by passing the neat solvent that dike bank 10 enters second liquid bath 4 at this.The wool that cleaned like this continues to be transmitted by conveyer belt 6, cross roller 19, direction with arrow 20, be transported out equipment 1, be admitted in the centrifuge then, in this centrifuge, stick in residual solvent on the wool and be thrown out of gasification (or partial gasification, part still for liquid), and sent back to finally that (referring to Fig. 2) reused to send back to once more in the equipment among Fig. 1 in the initial clean solvent container.As 2 of flow charts clearly indicate ground, whole system among this embodiment of the present invention seals, and solvent recycles, and equate by the speed that dike bank 10 enters second liquid bath 4 with neat solvent from the speed of first liquid bath, 3 output solvents, like this, the liquid level of the solvent 13 in first liquid bath 3 and second liquid bath 4 just can keep stable basically in the system.

Shown in Fig. 2, the clean solvent of extracting out from the solvent storage case is crossed dike bank 10 and is entered liquid bath 4 with the last wool purificant before casing as wool.As described above, a part of solvent in second liquid bath 4 reenters in second liquid bath 4 by spray equipment 9 through a filter.Used solvent is transported in first liquid bath 3 by dike bank 8 in second liquid bath 4.Solvent in first liquid bath 3 comes back in first liquid bath 3 by spray equipment 7 after filtering once more.Used solvent will be through one group of filter in first liquid bath 3.The dirt that these filters filtered out enters in the dirt collection chamber after through a dirt drier, and in this chamber, these dirts are pulverulence and are collected in together.In addition, the dirt that filters out from spray filter also can be transported in this group filter and go.Solvent that comes out from these filters and grease are transported in a series of distillers, and at this, grease is separated and is collected in one or more grease collecting boxs.In these distillers, solvent is evaporated out these gasifications then from the mixture of solvent and grease solvent is condensed and turns back in the solvent storage case.Isolated solvent also is sent in this solvent storage case from the dirt drier, the vaporized solvent that results from liquid bath 3 and 4 is sent to condensation in the condenser, and, make these vaporized solvent also by in condenser owing to the air pressure in liquid bath 3 and 4 remains on the effect that produces a kind of power slightly less than the level of normal atmosphere (An).The vaporized solvent steam that comes from centrifuge and the dirt drier is sent in the condenser too.Vaporized solvent condensation in condenser also is transferred back in the solvent storage case, to be applied in the system again.

Whole system seals, and remain under the negative pressure, escape in the atmosphere with the vaporized solvent steam that is used for anti-locking system and to go, at this point, also used a steam reduction apparatus, this device is held the steam in the system under negative pressure, and is condensed to carry back in the neat solvent container, so that be used again.An activated carbon adsorption unit meets the severeest environmental protection standard as the tail gas adsorbent equipment to guarantee the tail gas of discharging.

Find in actual applications, owing to from system, contain 2% solvent composition in the isolated grease, make solvent that some trace losses be arranged, like this, add all a small amount of solvents of overflowing, the total losses amount of solvent estimates between every day 70-100 kilogram, and this is given for one, wool input quantity hourly is that 750 kilograms (containing grease) and solvent distillation speed hourly are 6500 kilograms system, and this loss is an acceptable.

Can estimate like this that one keeps constant per hour 5000 liters the neat solvent input quantity of second liquid bath 4 to be offset by the solvent output quantity of one per hour about 5000 liters second liquid bath, 4 to first liquid baths 3.The wool that soaks that enters second liquid bath 4 from first liquid bath 3 speckles with some solvents, like this since wool on solvent, in fact should be from the solvent that second liquid bath 4 flow back into first liquid bath 3 than per hour more than 5000 liters.By a suitable control valve, the spraying cycle solvent flow in first liquid bath 3 in second liquid bath 4.A liquid-level controller is used for detecting the solvent liquid level height of second liquid bath 4 and by above-mentioned control valve enough solvents is turned back in first liquid bath 3, makes it to keep a constant liquid level to offset the clean input quantity in the liquid bath 4.

Per hour 5000 liters the solvent that comes from the wool treatment facility 1 flow in one first distiller that moves under being lower than atmospheric pressure, in order to obtain constant content from this first distiller is 30% yolk, is taken out yolk continuously with about 330 kilograms/hour speed from first distiller and is sent in the after-fractionating device by the first distiller grease drawing pump.And the solvent of condensation is extracted out and is delivered in the clean solvent container by the solvent drawing pump of first distiller again.

In the after-fractionating device, come from grease in first distiller and be concentrated to 80% grease concentration, oil pump in the after-fractionating device with 120 kg/hour speed the grease of this concentration is pumped in the 3rd distillery, and the clean solvent of condensation is pumped in the pure solvent container by the solvent drawing pump of after-fractionating chamber again.In the 3rd distiller, distillery is electrically heated, and the solvent that has gasified is to extract out by the injection pump in the solvent compartment that is immersed in cooling solvent under the normal pressure.This chamber makes the solvent condenses of gasification, this condensation that the liquid level in the solvent compartment is risen by air conditioner cooling and wherein solvent is overflowed and flows in the clean solvent container.Therefore, in the 3rd distillery, no longer need the liquid solvent drawing pump.

Solvent in the clean solvent container is pumped in second liquid bath 4 by the clean solvent pump with 5000 liters/hour constant speed.Liquid level in the clean solvent container is controlled by liquid-level controller.If cause the liquid level of container to descend because the quantity of solvent that flows back to from equipment is less than the quantity of solvent (owing to solvent loss) of the equipment of pumping into, then a solvent make-up pump can be in addition accumulates the case some solvents of extraction from a solvent and delivers in first distiller and go.

When the liquid level in the clean solvent container rose, the part that then wherein has more can directly be overflowed, and accumulates in the case and flow back into solvent.

As the residue of distiller, yolk is progressively concentrated, and when it took out from distiller at last, its concentration surpassed 95%.

Because the use of various pumps, the circulation of solvent has expended considerable energy.These pumps comprise the spraying cycle pump, flow the drawing pump of pump and solvent and yolk altogether.In order to prevent that the solvent temperature that is arranged in

liquid bath

3 and 4 from rising so high, on each liquid bath, be provided with refrigeration, and these preferably are positioned at the bottom of the inlet zone of liquid bath around pipe around pipe.The cold air that comes out from total distilled refrigeration device is supplied these around pipe, and like this, by a simple numerical attemperating unit, the temperature in the liquid bath is just adjusted at an easy rate.

Vaporized solvent control is peculiar technical characterictic important in the system of the present invention.All solvent apparatus for placing, for example liquid bath 3,4, and filter, container, centrifuge or the like all are under the little negative pressure.So only can each closely junction the inflow of little air appear, and air/vaporized solvent is flowed out, thereby avoid the solvent loss of extra gasification.In order to keep a desirable negative pressure value, a small fan is connected the suction side of all solvent apparatus for placing.The air that contains the solvent that gasifies of being discharged by this fan is admitted to the gaseous solvent steam reduction apparatus that a refrigerating plant and activated carbon adsorption unit combine.Wherein, set refrigerating plant can make the steam that contains the solvent that gasifies be cooled to subzero 30 degree.Cooled vaporized solvent is reheated environment temperature.At cooling stage, vaporized solvent is condensation, and in residual gas residual only about 4% vaporized solvent.By the activated carbon adsorption unit of a less relatively and lower cost, this device can adsorb 98% residual gaseous solvent to this residual gas then.Make the lost loss of vaporized solvent reach 17 kg/day like this.The gas that comes out from the vaporized solvent reduction apparatus is discharged from the factory building that is provided with this device, and is discharged at last by an exhaust duct.

Therefore; whole system sees it is can be received from point of view of environment protection; all dirts can both not removed from wool on solvent and the wool because whole system can or can not be overflowed hardly; and be collected; specifically; dirt can collect as fertilizer sources, and grease can be used for above-mentioned further processing, and vegetable matter can be used for tradition processing subsequently.Therefore the product of whole system is clean, that put in order, that quality is high wool, pulverous dirt and than the high yolk of traditional washing process rate of recovery.Wash out contain grease dirt and the protide industrial waste is considered to usually, river for example, pollutant.System of the present invention has then avoided these refuses fully.
