查询词典 liquefied petroleum gas

The temperature of flue gas out of air preheater in boiler is normally about 120～180℃, the flue gas enter the absorb tower from the bottom via pre-deduster and is accelerated by venturi tube at the bottom of absorb tower, then is taken to circulating fluid bed. The materials are in the circulating fluid bed, due to the effect of flow, the gas-phase and solid-phase generate fierce turbulence and combination and are fully contacted, then form polymers constantly during the ascending and return downward, while the polymers are constantly disassembled during fierce turbulence and elevated by airflow, which makes the slip velocity between gas and solid reach the tenfold times of single slip velocity.

首先从锅炉的空气预热器出来的烟气温度一般为120～180℃左右，通过预除尘器后从底部进入吸收塔，然后烟气通过吸收塔底部的文丘里管的加速，进入循环流化床，物料在循环流化床里，气固两相由于气流的作用，产生激烈的湍动与混合，充分接触，在上升的过程中，不断形成聚团物向下返回，而聚团物在激烈湍动中又不断解体重新被气流提升，使得气固间的滑移速度高达单颗粒滑移速度的数十倍。
