Abstract

The invention provides a device for joint production of fuel oil and cement semi-finished products by oil and sand pyrolysis. The device comprises a crusher, a first material discharger, a preheating dewatering tower, a material mixer, a lifting pipe and a pyrolysis reactor, wherein a material outlet of the crusher is connected with an inlet of the preheating dewatering tower through the first material discharger; a solid material outlet pipeline of the preheating dewatering tower is sequentially connected with the material mixer; the material mixer is positioned on the bottom part of the first lifting pipe; an outlet of the first lifting pipe is connected with the pyrolysis reactor; an air outlet of the pyrolysis reactor is connected with a fractionating tower; the downstream part of the fractionating tower is connected with a receiving device; a solid outlet pipe on the lower part of the pyrolysis reactor is connected with a heater. The device for joint production of fuel oil and cement semi-finished products by oil and sand pyrolysis has the advantage that the production cost is low.

Description

technical field [0001] The invention belongs to an oil sand cracking device, and in particular relates to a combined device for producing fuel oil and cement semi-finished products by cracking oil sand. Background technique [0002] Oil sands are sedimentary sands rich in natural bitumen. Therefore, it is also called "tar sand". Oil sand is essentially a mixture of asphalt, sand, rich ore clay and water, in which asphalt content is 10-12%, sand and clay and other minerals account for 80-85%, and the rest is 3-5% water. The bitumen is an oil sand bituminous oil with high density, high viscosity, high carbon-to-hydrogen ratio and high metal content. [0003] There are three main foreign oil sand separation technologies: hot water washing, solvent extraction, and pyrolysis and dry distillation. Depending on the structure of the oil sand, different separation methods are used. Generally, the water-lubricating oil sand is suitable for water washing separation, and the oil-lubr...
