The invention relates to the technical field of ethane
cracking, in particular to an anti-blocking quench
tower of an ethane
cracking device, which comprises a
tower body, two sections of random packing and one section of
structured packing are sequentially arranged in the
tower body from top to bottom, an angle steel tray is arranged below the
structured packing, a vapor-liquid two-phase feeding
distributor is arranged below the angle steel tray, and the gas-liquid two-phase feeding
distributor is arranged below the angle steel tray. The invention has the following beneficial effects: the outlet pressure of the furnace tube of the
cracking furnace is low, the cracking
hydrocarbon pressure is low, the
ethylene product selectivity of the cracking furnace is improved, and the
material consumption is reduced; separation of heavy components and diluted steam in the quench tower is facilitated; low-level heat of
pyrolysis gas can be recovered, and
heat exchanger load between compressor sections can be reduced;
mass transfer and
heat transfer in the quench tower are facilitated, and the
mass transfer and
heat transfer efficiency of the tower is improved; heavy components,
styrene and the like in the tower can be prevented from being subjected to
polymerization reaction to generate a
polymer to block a filler layer; the production of the device is not limited, and full-load or overload production can be met.
