<p>The invention relates to a furnace for the thermal desorption of petroleum silts. According to the invention, the furnace consists of a receiving and transporting subassembly (A) which is in connection with a subassembly (B) taking over the semi-solid petroleum cake from the sump, mounted on a reaction subassembly (C) which is enveloped in a subassembly (D) representing the fuel combustion chamber, mounted in connection with a radial rotation and supporting subassembly (E), which is in connection with a horizontal motion and scraping subassembly (F) and with a secondary vertical supporting subassembly (H) located above the subassembly (G), a subassembly (I) for the control of the subassembly (E) being attached thereto, the reaction subassembly (C) resting on a support subassembly (J) and the subassembly (A) comprising two semi-buckets (1 and 2) driven by a mechanism, from a crane, where the subassembly (B) consists of a truncated cone oriented with the apex downwards, externally provided with a heating jacket, having two sliding covers (3, 4) at the top part and a trap (5) at the bottom part, the subassembly (C) comprises a shaft (E) on which there are mounted two equidistant rows of six-arm scrapers (F), the shaft (E) resting, at its extremities, on a bearing support subassembly (H) provided with rolling thrust bearings, the bearing supports resting on two metal legs (G), at its top part, the subassembly (C) having four connection pieces, namely one connection piece (6) for the supply with starting material and three connection pieces (7, 8 and 9) for the discharge of the reaction products, some rectifying columns (a, b, c) with inclined baffle plates and Raschig filler being mounted as an extension of the connection pieces (7, 8, 9), after charging the hopper, the sliding covers (3, 4) being closed and the discharge trap (5) being actuated, the furnace heating being started by means of a burner (K) which is initially supplied with light liquid fuel.</p> |
