Abstract
The invention provides a draining composite column plate which is mainly used for fully utilizing the space in a column, improving the vapor-liquid mass transfer status of draining column plates, reducing the pressure drop of the column plate, reducing the entrainment, and improving the processing capacity, the operating elasticity and the separating efficiency of the draining column plates through arranging draining sieve plates with identical opening ratio on the draining column plates in a staggered manner and a layer of high regular filling material of 100-250 mm under the draining column plates. The novel draining composite column plate adopts the structure that 20-60 percent of sieve pores are arranged on the draining column plates; sieve plates with identical opening ratio are arranged in the position 3-6 mm away from the upper parts of the draining column plates; each sieve opening can be a circular hole with the diameter of 3-20 arranged on a plate of 2-10 mm, a diamond hole with equivalent opening area, and a strip-shaped bulge with a slot on the lateral surface; the circular hole, the diamond hole or the strip-shaped bulge on each sieve plate and the circular hole, the diamond hole or the strip-shaped bulge on each draining column plate are arranged in a staggered manner or a half staggered manner; the high regular filling material with the height of 100-250 mm is fixed under the draining composite column plate through a self bearing beam; upper bearing beams of the sieve plates are fixed among the plates of the composite column plate when the composite column plate is mounted; and the plate and a supporting ring are fixed by a connecting piece.
Description
1. technical field
The invention provides a kind of turbogrid type composite column plate, belong to the separation equipment field.
2. background technology
In petrochemical industry, the industrial departments such as petroleum refining, chemical industry, light industry, environmental protection, medicine and atomic energy, column plate and filler are widely used in distillation, absorption, extraction, absorption, washing, the unit processes in chemical synthesis such as cooling.The advantages such as it is high that filler has separative efficiency, and pressure drop is little, and disposal ability is large, but cost is larger, and operating flexibility is little, requires high to supporting tower internals; Operating flexibility of tray is large, anti-obstruction, and cost is low, and separative efficiency is relatively large, but pressure drop will be larger, and disposal ability is lower.Column plate is by having or not downspout can be divided into overflow-type column plate and throngh flowing type tray, and by contrast, existing throngh flowing type tray is simple in structure, and in tower, space availability ratio is high, and cost is low, and disposal ability is large, but vapour-liquid is short time of contact, and mass-transfer efficiency is low, and operating flexibility is little.The ideal column internals should have advantages of column plate and filler simultaneously, and namely low pressure drop, high efficiency, large operating flexibility, anti-obstruction, low cost, large disposal ability and Ta Nei space availability ratio are high.With column plate and filler compound be one of the effective way of tower internals of realizing ideal.
Compound overflow-type column plate compounded mix and the throngh flowing type tray compounded mix of mainly containing of column plate and filler, simple in structure due to throngh flowing type tray, to be easy to filler compound, is ideal column plate filler complex form.But existing dual-flow tray compounded mix is because the not high elasticity of composite plate and the load-bearing capacity of making of liquid flux of dual-flow tray is restricted.
3. summary of the invention
Purpose of the present invention is exactly a kind of turbogrid type composite column plate for the deficiency that overcomes the prior art existence.
Technical scheme of the present invention:
The objective of the invention is by increase the sieve plate of identical percent opening on dual-flow tray, arrange below dual-flow tray that one deck structured packing realizes, it can take full advantage of space in tower, improve the vapour-liquid mass situation of dual-flow tray, reduce plate pressure drop, reduced entrainment, improved the disposal ability of dual-flow tray, operating flexibility and separative efficiency.It is mainly by dual-flow tray, the formation such as sieve plate and structured packing, it is characterized in that having 20～60% sieve aperture on dual-flow tray, the distance of 3～6mm is provided with the sieve plate of identical percent opening at an upper portion thereof, sieve aperture can be the suitable diamond hole of φ 3～φ 20mm circular hole of opening on the thick plate of 2～10mm or perforated area, the strip bulge that cracks in the side, the wrong row of the circular hole of the circular hole on sieve plate, diamond hole or strip bulge and dual-flow tray, diamond hole or bar hole or half wrong row; Pass through self fixedly high structured packing of one deck 100～250mm of brace summer below dual-flow tray; During installation between composite plate plate and plate the upper support beam by sieve plate fix, fix by connector between plate and bracing ring.
The turbogrid type composite column plate that the present invention proposes, due to put on adopting sieve plate and under add structured packing, take full advantage of space in tower, increase at double air-flow time of contact, strengthened air-flow mixing intensity and contact interface renewal rate, improved plate efficiency, simultaneously due to the existence of sieve plate makes percent opening can be up to 60%, greatly improve disposal ability and the operating flexibility of column plate, reduced plate pressure drop and entrainment; Throngh flowing type tray serves as the liquid distribution trough of structured packing effectively, liquid is laterally mixed reach the desired perfect condition of filler; Conversely, the gas distributor of column plate has been served as again in structured packing, further improves the vapour-liquid mass situation, rationally effectively utilizes the advantage of column plate and filler, has reached both perfect adaptations.
