A petroleum hydrocarbon catalytic cracking device

Abstract

The invention relates to the technical field of petroleum processing equipment, in particular to a catalytic cracking device for petroleum hydrocarbon. The catalytic cracking device comprises a base,a tank body, a stirring mechanism, a storing mechanism, a traction mechanism, a first separating mechanism, a first cooling tank, a second cooling tank, a third cooling tank, a second separating mechanism, a third separating mechanism, a cold air pipe and an air delivery pipe, wherein the traction mechanism can drive the storing mechanism to move upwards; when a user pulls a top plate outwards andunscrews storing cylinders, a catalyst can be replaced, the operation is simple and convenient, and less time is consumed; cold air in the first separating mechanism can enter the second separating mechanism through the cold air pipe, and the cold air in the second separating mechanism can enter the third separating mechanism through the cold air pipe, so that precooling for a next stage of separating mechanism is realized, energy consumption needed when the next stage of separating mechanism works is reduced, flowing cold air can counteract external heat, the heating speed is decreased, theconstant temperature remaining time of the separating mechanisms is longer, and the energy consumption is lower.

Description

technical field [0001] The invention relates to the technical field of petroleum processing equipment, in particular to a petroleum hydrocarbon catalytic cracking device. Background technique [0002] Catalytic cracking is the process of high-temperature cracking of petroleum hydrocarbons to produce low-carbon olefins such as ethylene, propylene, butene, and light aromatics at the same time in the presence of a catalyst; due to the presence of a catalyst, catalytic cracking can reduce the reaction temperature, increase the yield of low-carbon olefins and light aromatics, and improve the flexibility of cracking product distribution. [0003] The contact surface between the current catalyst and petroleum is limited, the catalytic efficiency is insufficient, and it is troublesome to replace and maintain; when cooling and collecting petroleum mixed gas, it needs to consume a lot of energy to ensure the temperature in each cooling equipment. In view of this, the present inventio...
