Abstract
The invention relates to an efficient angle steel tray. The tray is formed by arranging multiple pieces of angle steel with upward apex at intervals, two sides of the angle steel are provided with streamline type overflow weirs, the lower edges at two sides of the angle steel are provided with sawteeth or fences and are installed on a bracing ring; and gas pores are arranged under the overflow weirs. A part of a gas passes the angle steel and the surface of a liquid-guiding plate, and a part of the gas is outwards injected from the interior of the angle steel, and thus gas-liquid mass transferring is finished. By additionally adding the streamline type overflow weirs at two sides of the angle steel, the liquid distribution is relatively uniform, and also the anti-blocking performance of the angle steel tray is improved. By additionally arranging the liquid-guiding plate, the gas-liquid mass transferring area is increased, and the tray efficiency is improved. Because of the sawteeth or fence structure at the edges of the liquid-guiding plate, a liquid uniformly falls off along the lower edge in a raining way, and gas-liquid contact is facilitated. Establishment of the gas pores increases the opening percentage, and the tray pressure reduction is effectively reduced. The angle steel tray is simple in structure, uniform in gas-liquid distribution, small in pressure reduction, large in mass transferring area, high in tray efficiency, and strong in anti-blocking performance, and is widely applicable to washing equipment, distillation equipment, absorption equipment, and other gas-liquid mass transferring equipment.
Description
Technical field
The present invention relates to a kind of high-efficiency angle steel column plate, belong to gas-liquid mass transfer (contact) equipment field.
Background technology
Angle iron tower plate is a kind of New Type of Tray that the seventies is developed by Japan.∨ type angle iron tower plate and ∧ type angle iron tower plate can be divided into by the placement location of angle steel.Angle iron tower plate has the advantages such as structure is simple, good rigidity, easy to process, pressure drop is low, is considered to a kind of column plate having promotional value and development prospect, is mainly used in the washing in chemical tower, temperature-reducing tower.But because angle iron tower plate gas liquid interfacial area is less, and angle steel shape makes gas-liquid contact in tower there is certain blind area, causes mass-transfer efficiency low, is further improved.
For the shortcoming of angle iron tower plate, Chinese invention patent 93226647.9 devises one and opens foraminate angle steel tower tray, is conducive to even gas distribution.Angle steel lower limb is opened sawtooth by Chinese invention patent 03257906.3,201120170253.5, is conducive to being uniformly distributed of liquid.But the angle steel tower tray related in above-mentioned patent all adopts the knockdown structure of top and seat angle, considerably increases pressure drop, reduces tray efficiency.
The object of the invention is to the shortcoming overcoming above-mentioned angle iron tower plate, a kind of anti-stifled high-efficiency angle steel column plate of design, has structure simple, uniform gas-liquid distribution, pressure drop is little, and mass-transfer efficiency is high, the advantages such as disposal ability is large, anti-clogging is strong, thus the mass-and heat-transfer efficiency improving angle iron tower plate further.
Summary of the invention
The object of the present invention is to provide a kind of high-efficiency angle steel column plate, improve mass-and heat-transfer efficiency and the anti-clogging of angle iron tower plate.
The object of the invention is to have come by following technical solution:
A kind of high-efficiency angle steel column plate, it is characterized in that column plate is made up of multiple angle steel gap arrangement, upwards, angle steel both sides arrange streamlined downflow weir to the top of the horn, and angle steel both sides lower edge arranges sawtooth or fence, and is installed on bracing ring; Downflow weir is to be arranged with pore.
The described direct crimp of both sides lower edge is draining plate, and draining plate lower edge is provided with sawtooth or fence, and the angle steel below downflow weir and draining plate are provided with pore.
The width range of described angle steel is 50mm ~ 600mm.
The angular range of described angle steel is 60 ° ~ 120 °.
The angle steel of its described upper and lower two-layer column plate is vertical or parallel.
Described streamlined height of weir plate is the 10%-50% of angle steel straight side width.
Described draining plate height is the 20%-200% of angle steel straight side width.
Described pore is tongue apertures, circular hole or rectangular opening.
Liquid is downward through angle steel the top of the horn, makes liquid distribution more even through downflow weir, under dropping liq is drenched by draining plate sawtooth or fence edge.Portion gas is from angle steel and draining plate surface process, and portion gas outwards sprays from angle steel is inner, completes gas-liquid mass transfer.
Compared with traditional angle steel, feature of the present invention is:
1. angle steel both sides add streamline downflow weir, make liquid distribution more even, and improve the anti-clogging of angle steel tower tray;
2. adding of draining plate adds gas-liquid mass transfer area, improves tray efficiency;
3. the sawtooth at draining plate edge or fence structure, make liquid along lower edge uniformly rain shape drench and fall, be conducive to gas-liquid contact;
4. offering of air rising hole adds percent opening, effectively reduces plate pressure drop.
