Abstract: The helical fractionating column according to the invention falls into the field of oil separation apparatus for the petroleum refining industry, which includes a column body (8), and is characterized in that the inside of the column body (8) is divided into three sections, the lower section being jet tray section, the middle section being packing section, and the upper section being floating valve section. The helical fractionating column has many advantages, such as having enhanced integrity of separation, decoloration and deodorization, simple structure, convenient manufacturing and maintenance, and low investment cost as well as high product quality etc. Thus, the present invention is worthy to be extended in the petroleum refining industry which uses waste plastics and rubbers as raw materials.

Abstract: A process and a device that produce gasoline, kerosene and diesel oil from waste plastic, rubber and machine oil, the device comprises sussively cracker, fixed bed, packed tower, fractionating tower, the top part of the fractionating tower connects with gasoline quencher, and the quencher links condenser, separator of oil and water, filter, and gasoline treating column in series, the latter is connected with filter, finished product tank; the kerosene fraction from the middle part of the fractionating tower and the diesel oil fraction from the lower part enter condenser, separator of oil and water, filter, and treating column in series respectively, the residue from the bottom returns back to the cracker. In this invention, quartz and sand are added during cracking; one step process is used in fixed bed; a chemical agent for removing the odor and changing the color is added during the fractionation.
