Abstract

The oil sludge cracking device comprises a cracking kettle provided with an oil sludge inlet, a gas outlet, an ash residue outlet and a gas inlet; the gas inlet is connected with a combustor, a plurality of temperature sensors are arranged in the cracking kettle, and the oil sludge cracking device further comprises a controller. The process comprises the following steps: turning off the gas supplyof the combustor after cracking, directly introducing air into the cracking kettle, combusting organic gas generated by cracking of the oil sludge to provide heat required by cracking, and controlling the supply amount of the air according to the real-time temperature in the cracking kettle to control the temperature in the cracking kettle to be a preset standard value. The continuous cracking ofthe oil sludge can be realized, the cracking efficiency and yield are improved, and the energy consumption is reduced; more importantly, organic gas generated in the cracking process is combusted, self-heating is achieved, and the purpose of controlling the cracking temperature is achieved by strictly controlling the air supply amount and adjusting the sufficiency of internal combustion.

Description

technical field [0001] The invention relates to the technical field of oil sludge treatment, in particular to an oil sludge cracking device and process. Background technique [0002] Oil sludge is mainly produced in the crude oil drilling process, the scum of the oil processing process, the bottom of the oil tank of the petrochemical plant, the bottom of the tanker and other environments. Its components mainly include 5-60% water, 5-70% oil (asphalt, rubber quality, etc.) and 10-40% mud. Oil sludge has considerable recyclable value because of its oil content. [0003] At present, oil sludge is treated by cracking. The main steps include distillation dehydration (to make water and light oil evaporate into gas and discharge) and heating cracking (380-550 ° C, to crack the residual sludge oil after distillation to produce non-condensable gas, Oil and charcoal), the processing equipment is a rotary cracking furnace, the furnace body is equipped with multiple burners, first put...
