Tower plate bearing structure of large-scale cross-flow plate type tower

Abstract

The invention discloses a tower plate bearing structure of a large-scale cross-flow plate type tower. Shaft sleeves are arranged on the upper ends of various upright posts at the bottom of the tower; pull rods are arranged among various shaft sleeves; liquid-receiving long grooves are supported in layers among the upright posts and between the upright post and a tower wall; the upright posts are supported at the two ends of the groove in a sliding mode; one end of the liquid-receiving long grooves between the upright posts and the tower wall is fixed with a tower ring; supporting unit tower plates are respectively arranged between each layer of the liquid-receiving long grooves and the tower ring; the layered tower plate consists of unit tower plates; and each unit tower plate is provided with gas lifting pores; liquid-outlet boxes are arranged above central parts of each unit tower plate of each layer of the tower plate arranged below the top layer of the tower plate; the periphery and the bottom of the liquid-outlet box are provided with liquid-outlet holes; and each liquid-outlet box is respectively provided with pipelines which are adjacently communicated with the groove bottom of the upper layers of each liquid-receiving long groove. The tower plate bearing structure overcomes the defect that a space between the tower plates caused by supporting beams of the traditional tower plates is oversize, thereby ensuring enough rigidity support of multiple upper layer and lower layer of tower plates, satisfying liquid-distribution and separation requirements, and being favorable to improving the whole-tower effect and reducing the cost of the tower.

Description

technical field [0001] The invention belongs to a tray tower, in particular to a tray supporting structure of a large cross-flow tray tower. Background technique [0002] The mass transfer of the cross-flow plate column is realized by the rising gas passing through the plate and contacting the liquid on the plate. The mass transfer and heat transfer usually only occur on the plate, and the liquid pool area on the plate is the gas-liquid transfer. The mass area, above the liquid pool is the gas-liquid separation area and the downcomer area, which resolves most of the entrained gas and makes the liquid fully mixed and then redistributed into the next layer of trays, which belongs to the step-by-step contact mass transfer. [0003] In the prior art, each tray of the tray tower is supported by cross-beams of sufficient strength, and the cross-sectional height of each cross-beam of sufficient strength will inevitably cause an excessive gas-liquid separation zone and downcomer zon...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, each tray of the tray tower is supported by cross-beams of sufficient strength, and the cross-sectional height of each cross-beam of sufficient strength will inevitably cause an excessive gas-liquid separation zone and downcomer zone between the two trays. , which reduces the space utilization rate in the tower, which is equivalent to reducing the mass transfer area, so the efficiency of the existing cross-flow plate tower is low, and the cost of the tower is also increased
