2, it is separated by specific gravity into waste water 39 and solvent 40,
As mentioned above, some solvent remains in the separated water in a dispersed state. When the wastewater 39 exceeds a certain amount, the excess amount is led to the water pipe 29 and stored at the bottom of the wastewater treatment device 30. When this drainage volume reaches a certain amount (preferably at the end of the day's work),
The steam valve 36 is opened to blow steam into the waste water 39.

公害発生を未然に防止できる。 The waste water 39 is heated and stirred by the injection of water vapor, and as the temperature of the waste water rises, the solvent in the waste water mainly evaporates and is discharged outdoors through the duct 34, and the solvent content in the waste water 39 is gradually reduced. Decrease. According to the results of the experiment, 100% of wastewater with a solvent concentration of 400ppm
When g/min of water vapor is injected, 115 ppm after 3 minutes,
After 7 minutes, the solvent concentration in the waste water decreased to 5 ppm.
After the solvent concentration has decreased, if the valve 32 is opened and the wastewater is disposed of outside the system, there is no risk of groundwater contamination.
Pollution can be prevented from occurring.

In this embodiment, the other end of a water pipe 29 attached to a conventional water separator 22 opens into a wastewater treatment device 30, and the lower part of the wastewater treatment device 30 is covered with a steam jacket 44, and the water pipe 29 is attached to a conventional water separator 22. The top of the jacket 44 communicates via a valve 47 with a steam pipe 49 to a steam supply (not shown). A drain discharge device consisting of a steam trap 46 is provided at the bottom of the steam jacket 44. Further, the upper part of the waste water treatment device 30 is open to the outdoors via a duct 34.

4 and heated by steam supplied from the steam pipe 49, the waste water 39 discharged to the waste water treatment device 30 is heated and evaporates into water vapor. As the wastewater 39 evaporates, the solvent contained in the wastewater 39 also becomes a solvent gas and is discharged outdoors through the duct 34 along with water vapor. Therefore, there is no wastewater containing solvents, and there is no risk of groundwater contamination, making it possible to prevent pollution from occurring.
Note that it is also possible to provide a temperature detection section at the bottom of the waste water treatment device 30 and open and close the valve 47 depending on the presence or absence of the waste water 39 to control the steam supplied to the steam jacket in order to save money.
