The valve 1 installed between the 20 and the liquid level tank 80 is closed to stop the supply of contaminated solvent, and the regeneration tank 20 continues to be heated by the steam or thermal oil pipe 100 in this state. do.

상기와 같이 용제의 공급이 중단된 상태에서 재생탱크(20)를 계속 가열하는 공정을 본 발명에서는 쫄임공정이라 하며, 이때 일정시간이 경과되면 재생탱크(20)에 설치된 밸브(2)(3)가 열려 재생탱크(20)의 전공을 해제하고, 동시에 재생탱크(20)와 슬러지탱크(50)의 사이에 설치된 밸브(4)가 열려 재생탱크(20)에 있는 완전 폐액(슬러지)은 슬러지탱크(50)로 방출된다.The process of continuously heating the regeneration tank 20 in a state in which the supply of the solvent is interrupted as described above is referred to in the present invention, the valve (2) (3) installed in the regeneration tank 20 when a certain time has elapsed Is opened to release the major of the regeneration tank 20, and at the same time, the valve 4 installed between the regeneration tank 20 and the sludge tank 50 is opened, and the complete waste liquid (sludge) in the regeneration tank 20 is discharged to the sludge tank. Is released at 50.

슬러지탱크(50)로 방출된 폐액은 냉각수라인(90)에 의해 냉각되어 외부로 드레인되어 본 공정이 완료되고, 본 공정이 끝나면 처음 공정을 반복하면서 계속하여 오염된 탄화수소계 용제를 재생한다.The waste liquid discharged to the sludge tank 50 is cooled by the cooling water line 90 and drained to the outside to complete the present process, and after the present process is repeated, the first process is repeated to regenerate the contaminated hydrocarbon solvent.

따라서, 이러한 오염된 탄화수소계 용제를 재생하여 세척수로 재활용할 수 있는 장점이 있으며, 이를 통해 오염된 탄화수소계로 인한 환연오염을 미연에 예방할 수 있는 장점이 있다.Therefore, there is an advantage that can be recycled to the wash water by regenerating such contaminated hydrocarbon solvent, through which there is an advantage that can prevent the pollution pollution caused by the contaminated hydrocarbon system in advance.
