 The device contains an additional filter, additional means for returning the purified solvent to solvent spraying means in the first tank 1 (not shown conventionally in the drawing). The main and additional filters are mounted with the possibility of separate input of solvent from tanks 1 and 13. The device is equipped with a refrigerator, means for heating solvent vapors from tanks 1 and 13 and a centrifuge in the refrigerator, means for transferring solvent from the refrigerator to the tank, an output trap for receiving residual vapors from the refrigerator, made in the form of an activated angle adsorber in communication with the atmosphere, by an auxiliary filter group for receiving the used solvent from the first tank and with impurities and fat inclusions, means for transferring waste material from the main and additional filters to the auxiliary filter group, a dryer and a number of distillation cubes for transferring grease inclusions and solvent to them from the filter group, means for removing solvent from the dryer and distillation cubes and transfer it into the tank, a chamber for collecting foreign material from the dryer and an additional tank for collecting fat inclusions from distillation cubes (not shown conventionally in the drawing). The device is sealed from the surrounding atmosphere for operation below atmospheric pressure.

 The device operates as follows.

 The wool is moistened and fed to the input zone 3. The wool falls on the surface of the conveyor belt 5 in the tank 1 and is transmitted through it at a given speed.

 Part of the solvent 2 in the tank 1 is directed to the medium 12, where it is forced to flow into the endless belt of the conveyor 5. An additional part of the solvent 2 in the tank 1 is passed through the filter to the solvent spraying means 7, where it is forced to flow vertically downward for mixing with the solvent 2 to remove grease and foreign material from wool. The endless tape 5 and the wool passed through it are raised above the surface of the solvent 2 between the rollers 17 and 18 of the tape, in a raised section 6, the wool is washed with a solvent 2 sent from the second tank 13 through the drain 11 to further remove grease and foreign particles in this wool.

 Thus washed wool is transferred along the endless belt of the conveyor 5, falls onto the endless belt of the conveyor 15 in the second tank 13 and then part of the solvent 2 in the second tank 13 is used as a joint liquid flow through the means 21. Another part of the solvent 2 is transmitted through the filter to the means 19 from where it is transferred under pressure vertically downward for mixing with the solvent 2 in the zone of the endless belt of the conveyor 15 to further remove grease and foreign particles from the wool.

 A part of the endless belt 6 rises above the level of solvent 2 in the tank 1 between the rollers 17 and 18, and the wool transferred to the raised section 16 is washed with a clean solvent supplied to the tank 13 through the drain 20. The washed wool is sent along the endless belt of the conveyor 15 to the exit 14, then it is transferred to a centrifuge, where the remaining solvent mixed with wool is removed and transferred in the form of steam (or partially in the form of steam and liquid) to return to the tank with a clean solvent and to the device.

 The solvent removed from the tank 1 at the same speed as the pure solvent is transferred to the tank 13 through the drain 20, and the level of solvent 2 in the tanks 1 and 13 is kept constant. Pure solvent is pumped from the solvent tank into the tank 13, while it enters the tank 13 through the drain 20 as a final washing of the wool until the wool reaches the cassette. Part of the solvent in the tank 13 is passed through the filter and then again introduced into the tank 13 through the means 19. The solvent used in the tank 13 is transferred to the tank 1 through the drain 10. A part of the solvent in the tank 1 is again filtered to be introduced into the tank 1 through the tool 7. The solvent used is passed from tank 1 through a series of filters. From these filters, foreign material is passed through a dryer to a foreign material collection chamber, where it is collected in powder form. Additional weed impurities from filters of means 7 and 19 are also transferred to this row of filters. The solvent and fat are transferred from these filters to a group of distillation cubes, from where the fat is extracted and collected in one or more collecting tanks.

 In distillation cubes, the solvent is evaporated from a mixture of solvent and fat, and such an evaporated solvent condenses and is returned to the solvent tank. The solvent from the weed dryer is also sent to the solvent tank. Vapors from blocks 1 and 13 are sent to the refrigerator refrigerator, while in tanks 1 and 13 the pressure is maintained at slightly lower than normal air temperature to create an effort to transfer the vapor to the refrigerator. Centrifuge vapors and impurity dryers are also transferred to the refrigerator, from where the solvent is returned to the clean solvent tank for recycling in the system.

 The whole system is sealed and is under atmospheric pressure to prevent the release of vapor into the atmosphere. In this regard, a vapor recovery means is used, into which the vapor from the system is drawn under atmospheric pressure. These vapors are condensed and transferred to the tank from a pure solvent for reuse in the system. A trap in the form of an activated carbon adsorption device is used for the final vapor recovery, so that the vapor emission is compatible with the most stringent environmental regulations.

 Loss of solvent will be minimized since the fat in the wool recovered from the system has a solvent content of approximately 2%. In addition to any slight vapor yield, this represents the sum of the total solvent losses of 70-100 kg / day. This is considered acceptable provided that the system is designed for a wool feed rate (non-fat-free) of 750 kg / h and a solvent distillation rate of 6500 kg / h.

 The inlet stream of 5000 l / h of pure solvent in the second tank will be kept constant, and this inlet stream will be balanced by the exit stream of about 5000 l / h from the second tank 13 into the first tank 1. Wet wool entering the second tank from the first tank will also carry with it a certain amount of solvent, so the return flow to the first tank will actually be higher than 5000 l / h by an amount carried forward by wet wool. The return flow to the first tank 1 is carried out from the second tank 13 in the form of a jet circulation stream through the corresponding control valve. The level controller will detect the level of solvent in the second tank 13 and send a sufficient amount of solvent back to the first tank 1 through this control valve to balance the total inlet stream and maintain a constant level of solvent.

 The solvent stream from the washing device of 5000 l / h enters the primary distillation cube, which operates at a pressure below atmospheric. To maintain a constant 30% concentration of wool fat in the primary distillation cube, approximately 330 kg / h is pumped out of the evaporator bath to extract fat from the primary distillation cube and sent to the secondary distillation cube. Then, the recondensed liquid of the pure solvent is pumped to extract the fat from the primary distillation cube into the tank for the pure solvent.

 In the secondary distillation cube, the liquid from the primary distillation cube is concentrated to a fat concentration of 80%. The stream of 120 kg / h is removed from the evaporation bath by a pump for extracting fat from the secondary distillation cube, and it is transferred to the third distillation cube. The recondensed liquid of the pure solvent is pumped to remove the solvent from the second distillation cube into the tank for pure solvent.

 In the third distillation cube, the bath is heated by electric means, and solvent vapors are removed from the distillation cube by an injection pump immersed in a cold solvent bath at atmospheric pressure. The bath is cooled by cooling and the solvent vapor is condensed inside the bath. This causes the bath level to rise and the solvent stream overflows into the clean solvent tank. Thus, a third pump is not required to recover the liquid solvent.

 In the second tank 13 is constantly pumped with a pump 5000 l / h of solvent from the tank for storing pure solvent. The level in the tank with pure solvent is regulated by a level regulator. If the level in the tank decreases due to the fact that the return flow from the washing device is less than the flow pumped into the washing device (as a result of solvent losses), then the solvent feed pump will pump additional solvent from the storage tank into the primary distillation cube.

 If the level in the tank with pure solvent rises, the excess will be returned to the tank for storing the solvent.

 The fat from the wool is gradually concentrated in the residues from the distillation cubes to a concentration of over 95% fat when unloading from the final distillation cube.

 Various pumps in the system add significant energy to the circulating solvent. These pumps include jet circulation pumps, co-flow pumps, and solvent and grease recovery pumps. To avoid an excessive increase in the temperature of the solvent in the tanks 1 and 13 in each tank in the injection zone under the return tank installed refrigerated coil refrigerator. Cooling can be supplied to this coil from the main distillation unit for distillation cubes, and the temperature in the tank can be easily adjusted using a simple thermostat with a dial.

Vapor control is important. All solvent-containing devices, such as filters, tanks, centrifuges, etc. support under pressure slightly below atmospheric. This creates a small flow of incoming air during any leakage, and not the outgoing flow of air / solvent, thereby eliminating the loss of vapor of the solvent. To maintain the required pressure below atmospheric, a small fan is connected on its suction side to all devices containing solvent. Solvent-loaded air and discharged from the fan is directed to a vapor recovery system using refrigerated and absorption recovery of coal vapor. It is possible to apply the refrigeration system for cooling the saturated solvent vapor to approximately -30 ° ^C. After cooling the solvent vapors will be reheated to ambient temperature. During the cooling step, the solvent vapor condenses, leaving only about 4% of the vapor in the air. This stream is then sent to a relatively small and inexpensive coal absorption system, which absorbs approximately 98% of the remaining solvent vapor, and thus the emission loss of the solvent vapor is reduced to about 17 kg / day. The release of steam from the regeneration system is carried out out of the room in which the system is located through an exhaust pipe.

 The whole system is environmentally friendly, since there is no solvent leakage from the system, all foreign material is removed from the wool and collected, particles in the form of weed impurities can be used as fertilizer, fat for further processing, plant substances for subsequent processing in known processes. The products of the system are pure, high-quality non-tangled wool, impurities in powder form and more highly reduced fat from wool.
