Special oil-sludge cracking device and oil-sludge cracking process

Abstract

The invention relates to a special oil-sludge cracking device and an oil-sludge cracking process, belonging to the technical field of equipment and processes for preparation of fuel oil from oil sludge. The special oil-sludge cracking device comprises a feeding system, a cracking furnace (4), a heating system (5) and a discharging system (6). The special oil-sludge cracking device is characterized in that the feeding system comprises a driving device (1) and a screw feeding mechanism (3), the screw feeding mechanism (3) comprises a conical screw propeller (301), the conical screw propeller (301) is provided with a conical screw section of which the diameter is decreased gradually, a feeding cylinder (302) which adapts to the conical screw propeller (301) is sleeved by the conical screw propeller (301), one end of the conical screw propeller (301) is used for driving through the driving device (1), the other end of the conical screw propeller (301) is extended into the cracking furnace (4), and the upper part of the conical screw propeller (301) is provided with a hopper (303). The special oil-sludge cracking device and the oil-sludge cracking process have the advantages that automatic and continuous feeding and discharging can be realized, oil and gas leakage can be prevented, and the efficiency is high.

Description

technical field [0001] The special cracking device and cracking process for sludge belong to the technical field of equipment and process for producing fuel oil from sludge. Background technique [0002] Oil sludge is the product formed when the residual oil in the oil field enters the nearby soil and mixes together. With the increasing amount of oil sludge, the pollution of the surrounding environment and soil is becoming more and more serious. If the oil sludge can be fully utilized for fuel oil extraction, it will not only solve the problem of environmental pollution, but also improve the utilization rate of waste resources. The development and utilization of energy provides a new way of thinking. Among them, extracting fuel oil by pyrolysis is the most economical, scientific, and high-efficiency fuel oil extraction method. However, due to the characteristics of oil sludge such as high viscosity, there is no special equipment and process for oil sludge cracking in the p...
