The machine contains an installed g, a housing with a rotary cavity, perforated washing drum 1 for products, connected by means of FJOB- breeders with a drying and recovery system, having a fan 2, an air filter 3, a refrigerator 4 and feces. reefer 5. Pipeline 1 is connected through the trap 6 and the pump 7 to the tank 8 for storage; and the pure solvent 5 is the heat-efficient j and the tanks 9 and 10, filter I, connected through the plug 12 to the evaporator 13 of the distilled system, im. gr. Dust collector 14.

The evaporator 13 of the distilled system is connected through pipelines to a heat exchanger ISj, a condenser; b a separator 17 and tanks 8., 9, and 10.

The heat exchanger 15, installed between the evaporators 13 and the condenser 16, consists of: from the coaxially arranged pipes 18 and 19 ,, the inlet to the internal pipe 19 is connected to evaporate, p1; p; 13 ,, and the output - with a capacitor 16 "En:: - n pipe 18 is designed as truncated445

The outer tube 18 has an inlet 22 DL supply of cooling: Tsei Vod: in full.;:. The BKBi iHiiH pipe is located on the lateral surface of the pipe at the Granite with a large span of 20 s with the direction from top to bottom along the tangent to this height and the outlet 23 for discharging the cooled m /. the lateral surface of the Granzah L:; al; 1 with a base 21 and directed horizontally –1no tangentially to the side surface in the direction of the inlet nozzle 22. The inlet and outlet nozzles 22 and 23 are located in parallel planes, perpenes, cycls pp1, and the axis of the outer pipe 20.

The machine works in the following way. After loading the text: batch products into the washing machine. Raban 1 mortar: about pump 7 is fed from tank 10 to the sink} 1st drum to the first sink. At the end of the wash, the solvent from the washing drum 1 through the trap 6, to carry out the second wash, the solvent from the tank 8, the assassm 7 is fed to the washing drum 1,

In the process of washing, the washing tank takes place; and the solvent according to the scheme is drum 1 - catching 6 - pump 7 - filter 1 1 - washing, drum 1, - At the end of the second washing, the solvent from washing

the drum 1 is drained through the trap into the tank 10. To impregnate (impart certain properties to the product, such as water repellency, antistatic properties, etc.), the solvent from the tank 9 is pumped into the washing drum 1 by the pump 9. At the end of the impregnation, the solvent from the washing drum 1 through the trap 6 is discharged into the tank 9.

When distillation, solvent vapors coming from the evaporator 13 pass through the heat exchange 15. Here they condense, which significantly discharges the operation of the condenser 16, reducing its size, and, consequently, reducing the metal intensity of the machine.

When conducting experimental studies, the variants depicted in FIG. 3

 The location of the heat exchanger nozzles in; 1bir 1 was obtained from the condition of: maximal washing of one and the same ke of water with cooling, water, its surface (Fig. 3, PO 3.1 and 6).

At position 6, water moves linearly, does not mix, and only the boundary layer participates in heat exchange. The upper layers of water do not have time due to the high flow rate to take part in heat and mass transfer,

In positions 1, 3, and 5, the water moves in a spiral, it splashes, increasing the interactivity of contacting the entire mass of water, ensuring the interchangeability of the boundary layers due to mixing without any additional devices. At positions 2 and 4, the washing is less intense than at positions 1.3 and 5, since there are no spiral flows and there is no intensive mixing from above to the bottom of this surface, and the side for diverting the cooling positioned on the lateral border with a small base. horizontally horizontally to the side surface of the leg nozzle, with the elbow nozzle of the planes,

cooling the solvent vapors according to the heat exchanger – condenser of the distiller circuit due to more efficient heat exchange in the heat exchanger allows not only reducing the consumption of cooling water, but also the size and weight of the condenser of the distiller, and consequently, the machine as a whole. Experimentally, when measuring the specific consumption of water in l / kg of clean clothes, the angle between the side surface of the pipe and its axis is in the range from 6 to 10 °.
