Second step, the temperature that described extractor is arranged is about 120 DEG C, pressure is 0.1Mpa, it is simultaneously entered the low-pressure steam of 0.1Mpa, the second rabbling mechanism coordinating described extractor to arrange makes water and soil mixture react further, the time of reaction is about 60 minutes, and water and soil mixture fully enters described flash tank from the top of described extractor by described two-way valve afterwards；
3rd step, water and soil mixture enters described flash tank, fully enters settlement separation tank from top from top, and the saturated steam produced in flash process enters mixing channel by the pipeline described in claim 4, recycles；
4th step, the temperature that described settlement separation tank is arranged is about 90 DEG C, and the settlement separate time is about 30 minutes, after being sufficiently separated, described dimer (fatty acid) yl is derived by the mouth of leading described in claim 5, and described clay dregs is completely drawn out by the second pump described in claim 5, and mummification is reclaimed.
The beneficial effects of the present invention is:
(1) in the hargil after reclaiming, the content of dimer (fatty acid) yl is reduced to 1% from the 7% of traditional method, improves the response rate, more environmentally-friendly, and is easy to promote；
(2) greatly reduce the loss of human and material resources, and improve the efficiency of recovery.
