Waste engine oil catalytic cracking device

Abstract

The invention provides a waste engine oil catalytic cracking device, and relates to the field of waste engine oil recycling. The device comprises a reaction tank, a feeding pipe, an air inlet pipe, a liquid distribution pipe and a waste gas pipe; the feeding pipe is arranged on the outer wall of one side of the reaction tank, the air inlet pipe is arranged on the outer wall of the other side of the reaction tank, the air inlet pipe and the feeding pipe are both communicated with the reaction tank, one end of the air inlet pipe is communicated with the output end of an air pump, the liquid distribution pipe is arranged on the outer wall of the top end of the reaction tank, the waste gas pipe is arranged on the outer wall of one end of the liquid distribution pipe, a slag discharging opening is formed in the outer wall of the bottom end of the reaction tank, and a filter plate mechanism is arranged on the inner wall of the reaction tank. According to the waste engine oil catalytic cracking device, impurities are prevented from entering the liquid distribution pipe and blocking the liquid distribution pipe, the impurities can be discharged in time along the slag outlet, meanwhile, the cleaning plate can also play a cleaning role on the limiting plate, and the impurities are prevented from being adhered to the limiting plate.

Description

technical field [0001] The invention relates to the technical field of waste engine oil recovery and utilization, in particular to a waste engine oil catalytic cracking device. Background technique [0002] The so-called waste engine oil refers to the fact that the engine oil is mixed with impurities such as water, dust, other miscellaneous oils and metal powders produced by machine wear during use, resulting in blackening of the color and increased viscosity; Acid, colloid and asphalt-like substances, the regeneration of waste engine oil is to remove impurities in the engine oil by sedimentation, distillation, pickling, alkali washing, filtration and other methods. They are toxic substances and belong to the solid hazardous waste marked by the state. [0003] During the catalytic cracking of waste engine oil, since the waste engine oil will contain a small amount of impurities that have not been completely removed, at the same time, in the process of catalytic cracking, the...
