1. Product Characteristics
Packed tower has the advantages of high efficiency, large production capacity, small resistance, small sluggage and no obvious amplification effect. In addition to the ripple inside the tower, the reasonable design of the inner parts of the tower also plays a great role, especially the lack of obvious amplification effect, which embodies the importance of the structure of the inner parts of the tower.
2. Main Structure
The inner parts of the tower are mainly composed of liquid collector, filter, liquid redistributor, packing support, packing ring, etc.
The collector is of shutter type, divided into two types: central collecting (type A) and jacketed annular collecting (type B). The design requirements of the collector are: to ensure that more than 98% of the liquid is collected, the gas passage is more than 50%, the necessary passage to ensure the smooth flow of the liquid, and the gas and liquid pass through the collector without resistance.
Prevent mechanical impurities and polymers that may be produced during operation from being brought into the distributor and clogging the liquid distributor.
The uniformity of gas velocity in the tower depends on the uniformity of liquid distribution. In order to distribute the liquid evenly, a row pipe distributor or a multi-stage slot distributor is used to meet the requirements of different corrugated packing and liquid load.
The supporting device is a grid, which is welded by flat steel and flat steel coil. It has simple structure and convenient manufacture. The free passage of the grating must be greater than 90%.
Prevent updraft from disturbing the top packing. Welding of flat steel or flat steel ring into well shape.
