Description

[Detailed Description of the Invention] The present invention relates to a distillation apparatus, and is for distilling a polluted solvent that has been washed or is being washed and reusing it as a clean solvent.

Conventionally, there have been various distillation apparatuses of this type, all of which have a heating mechanism for heating the polluting solvent and a cooling mechanism for condensing the evaporated vapor.

However, cleaning devices that use solvents for cleaning usually also have a cooling section, and this cooling section is only used for cooling and drying the objects to be washed.

The present invention eliminates the need for a cooling mechanism for the distillation apparatus by condensing the evaporated vapor using the cooling section of the washing apparatus.

An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes an evaporation tank having an outer circumferential wall 2 formed of a heat insulating material, which houses a polluting solvent 3 and a heating mechanism for heating and evaporating the polluting solvent 3. 4 is formed.

5. A flexible hose that can be bent is used as an outlet pipe for guiding the evaporated steam generated by heating by the heating mechanism 4 of the cigarette to the cooling section 7 of the washing device 6.

A cooling pipe is formed in the cooling part 7 to which the outlet pipe 5 of the 8-cigarette smoker is connected, and is wound around the upper inner wall surface of the washing device 6 and allows cooling water or cooling gas to flow therethrough.

Reference numeral 9 denotes an annular baffle plate located inside the cooling pipe 8 at an appropriate interval, and causes the evaporated vapor of the solvent introduced from the outlet pipe 5 through the introduction hole 10 to collide with the cooling pipe 8. This provides good contact and improves condensation efficiency.

11 is an annular socket groove formed on the outer periphery of the lower end of the cooling section 7;
The condensed solvent adhering to the cooling pipe 8 is collected by dripping, and is led to the water separator 13 that separates the solvent and water through the discharge pipe 12. After extracting only the solvent, it is sent to the cleaning device 6 through the reflux pipe 14. into the washing phase 15.

Reference numeral 16 denotes a connecting pipe that connects the lower end of the cleaning phase 15 filled with the solvent 17 of the cleaning device 6 and the upper part of the evaporation tank 1. A pump 18 is located in the middle of the pipe to suck out the contaminated solvent 17 of the cleaning phase 15 and evaporate it. It is led to tank 1, evaporated and used again as a clean solvent.

However, the polluted solvent 3 is not necessarily supplied to the evaporation tank 1 from the connected washing device, but may be supplied completely separately.

As described above, the present invention utilizes the cooling section of the washing device to condense the evaporated solvent, so there is no need to provide the evaporator with any cooling mechanism, making it possible to form the device at low cost and downsizing the device. It is also an extremely economical device that does not consume any extra energy for cooling.
