In the energy recovery system of the catalytic cracking unit of the oil refining division, a third-stage cyclone separator (called three-cyclone for short) is one of key equipment, the performance of the third-stage cyclone separator and the design and manufacturing quality of the third-stage cyclone separator directly influence the service efficiency and the service life of a smoke machine and directly influence the economic benefit of enterprises. In recent years, catalytic cracking adopts a new technology of completely burning high-temperature regenerated carbon monoxide, so that a new process for catalyzing residual oil and heavy oil is realized, and the pressure and the temperature of a regenerator are greatly improved. In order to save energy, reduce consumption and increase benefits, the catalytic cracking energy recovery system is inevitably paid attention by various domestic oil refineries. Whether the energy recovery system unit can run for a long period or not is determined by the main factor of the energy recovery system unit, except the design and manufacturing quality of the energy recovery system unit, namely the quality of smoke entering a smoke machine. Since the flue gas from the regenerator contains a certain amount of catalyst, the catalyst will abrade the tobacco smoke blades, and when the tobacco smoke blades lose weight to some extent due to abrasion, the energy recovery system will be rendered ineffective. A large number of tests and theoretical researches prove that the concentration of the smoke catalyst and the particle quality entering the smoke machine are main factors causing abrasion to the blades of the smoke machine. In order to ensure the quality of the smoke entering the smoke machine (the concentration of catalyst dust contained in the smoke is less than 200mg/m3, and the maximum dust diameter is less than 10 μm), the smoke coming out of the regenerator must be dedusted and purified by a third-stage cyclone separator before entering the smoke machine.
