Device of phenolic constituents result is carried in extraction of well low temperature coal tar

The utility model provides a device of phenolic constituents result is carried in extraction of well low temperature coal tar and draw the method, including extraction apparatus, 1# distiller, 2# distiller, 1# extractant storage tank, 2# extractant storage tank to and 2# extractant regulation jar, wherein, the extraction apparatus is a plurality of and series connection, and jar 2# extractant quantity with assurance first order extraction apparatus is adjusted to the surplus 2# extractant that enters into mutually of the collection of the last grade of extraction apparatus at least, and the extract phase of the last grade of extraction apparatus enters into 1# extractant storage tank after distilling, the extract phase of other extraction apparatuss except that the last grade of extraction apparatus enters into the next stage extractant, the surplus 2# extractant storage tank that enters into after the distillation mutually of collection, the export of 2# extractant storage tank links to each other with all the other the extraction apparatus entrys except that first order extraction apparatus. The utility model discloses an extractant extracts many times, the content of impurity neutral oil in the reducible extract phase, and through 3 extractions, the relative purity of phenol can reach more than 97%, through 5 extractions, but the relative purity da genggao of crude carbolic acid.
