Tangential distribution-type large-diameter multi-inlet gas distributor and application thereof in carbon dioxide adsorption tower

Abstract

The invention discloses a tangential distribution-type large-diameter multi-inlet gas distributor and an application thereof in a carbon dioxide adsorption tower. The tangential distribution-type large-diameter multi-inlet gas distributor is arranged in an adsorption tower of which the diameter is more than 1200mm, and comprises a plurality of intake pipe mouths respectively and evenly distributed on the outer side of the distributor; the intake pipe mouths are all arranged from bottom to top; an included angle alpha between the central axis of intake pipes and a normal plane parallel to an overlooking plane is 35-40 degrees; and an included angle beta between the central axis of the intake pipes and a tangential plane parallel to a main sight plane is 35-45 degrees. The gas distribution evenness of the carbon dioxide adsorption tower during charging is realized; the design of the internal part of the traditional gas distributer is simplified, so that gas distribution is evener, and the pressure drop is lowered; and the phenomenon that an upward baffling mode is adopted because the traditional gas distributer adopts the feeding multiphase state can be omitted, thereby bringing convenience for collecting separated liquid phase and ensuring that only gas phase upwards flows to realize the purpose of gas phase and liquid phase separation. The tangential distribution-type large-diameter multi-inlet gas distributor has an important meaning in a large tower device of the type.

Description

technical field [0001] The invention relates to an air intake uniform distribution equipment for large-diameter carbon dioxide absorption tower equipment, in particular to a gas distributor capable of simple structure, promoting uniform gas distribution and reducing pressure drop in a single gas phase air intake state. Background technique [0002] The tower is a gas-liquid, liquid-liquid contact mass transfer equipment widely used in the petroleum and chemical industry. In the past ten years, with the increasing maturity of packing technology, large packed towers have gradually been successfully applied in industrial production. For a packed tower with good performance, the high performance of the packing itself is important, but the matching tower internals, especially the liquid distributor and gas distributor, are also crucial, otherwise the high performance of the packing cannot be fully realized. Especially for the packed tower with large diameter and shallow bed, the...

Problems solved by technology

And when the intake state is a single gas phase, using the traditional gas distribution to experience a feed baffle and upward process will not only increase the unnecessary pressure drop, but also the internal parts will affect the uniformity of the gas distribution process. sexual influence
