Embodiment 1

[0024] A small and medium-sized packed tower includes a tower body 1, a liquid distributor 2, packing 3, a support plate 4 and a gas distributor 5. The upper part of the tower body 1 is provided with a liquid distributor 2; the lower part of the liquid distributor 2 is provided with a support plate 4 for supporting packing; the lower part of the support plate 4 is provided with a gas distributor 5. The packing 3 is a layer of catalytic packing and a layer of structured packing stacked sequentially on the support plate 4 from top to bottom. Described catalytic packing layer 6 is a regular packing disc and includes two expanded nets, the packing layer 6 between the expanded nets and the spring 7 that is evenly arranged on one side of the expanded net along the width of the expanded net, and the length of the expanded net is the same as that of the spring 7 The length is equal, and the uniform concentric circle is rolled into a spiral shape. The liquid distributor 2 is a ring pl...

Abstract

The invention discloses a medium-and-small sized packing tower. The medium-and-small sized packing tower comprises a tower body, a liquid distributor, a packing, a support plate and a gas distributor, wherein the liquid distributor is arranged at the upper part of the tower body; the support plate used for supporting the packing is arranged under the liquid distributor; the gas distributor is arranged under the support plate; the packing comprises a catalytic packing layer and a structured packing layer which are sequentially stacked on the support plate from top to bottom; the liquid distributor is an annular plate which is fixed on the inner wall of the tower body; a cylindrical distribution slot is formed below the lower part of a middle pore channel of the annular plate and an interval is formed between the cylindrical distribution slot and the middle pore channel; a liquid redistribution pore plate is arranged at the bottom of the cylindrical distribution slot; liquid pores are formed in the liquid redistribution pore plate. The packing is high in porosity; the pressure reduction is reduced; a gas phase and a liquid phase can fully react. The medium-and-small sized packing tower is reasonable in structure, reliable to use and good in distillation effect, and is suitable for being widely popularized and used.

Description

technical field [0001] The invention belongs to the technical field of chemical equipment, in particular to a medium and small-sized packed tower. Background technique [0002] Packed column is one of the most commonly used gas-liquid mass transfer equipment, which is widely used in distillation, absorption, desorption, stripping, extraction, chemical exchange, washing and heat exchange and other processes. The tower body of the packed tower is a vertical cylinder, and the bottom is equipped with a packing support plate, and the packing is placed on the support plate in a random pile or a whole way. A packing hold-down plate is installed above the packing to restrict the movement of the packing with the updraft. The liquid is added from the top of the tower, sprayed onto the filler through the liquid distributor, and flows down along the surface of the filler. The gas is fed from the bottom of the tower, and after being distributed by the gas distributor, it flows counterc...
