Abstract
The utility model discloses a draining flow pattern multilayer step angle profile tray, whose gas and liquid contacting element is composed by angle profile, which also has a multilayer structure of orderly arraying in horizontal direction and vertical direction. The advantages of the utility model are that: (1), the tray has no directly communicated gas phase channel, when gas and liquid are flowed in reverse, inevitably, a mutually draining flow state is formed, which effectively prevents the phenomenon of gas phase short-circuit, increasing the corresponding phases mass transferring area of per tower height, improving the efficiency of the tray. (2), the tray is provided with an upward horizontal plane and concave surface, not easily occurring stacking of solid particles, which is suitable for the unit operating processes such as absorbing, distilling, stripping and chemical reaction of the gas-liquid system contained with solid particles. (3), the structure of the tray is simple, the stiffness is good, the manufacturing cost is low, and the installation and maintenance are convenient.
Description
Technical field
The utility model relates to a kind of flow through type multi-step angular tower plate.
Background technology
Plate column is as gas (vapour)---and liquid phase border mass transfer apparatus has obtained extensive use in engineering fields such as chemical industry, oil, light industry, metallurgy and environmental protection, the core component that determines its function quality is a column plate.Developed and dropped into the column plate numerous types that engineering is used, but for advance contain in the tower liquid or tower in generate the system of the solid particle of high fraction in the liquid phase, the accumulation of solid particle on column plate be all because can take place in the column plate of most types, causes plugging fault and can't stable operation.That has seen at present examples of industrial application has flow through type macroporous plate and a flow through type individual layer plane angular tower plate.The flow through type macroporous plate is because of still easy accumulated solids on the board plane between sieve aperture, remove deposit so have to adopt clear liquid to dash the pouring mode, thereby in tower, introduce a large amount of extra liquid, increased the liquid phase load of tower, increased that withdrawal rate and light component tower tail band go out total amount at the bottom of the tower, the technical and economic performance of separation process has been had a negative impact.Flow through type individual layer plane angular tower plate adopts the angle section rib to go up the angle section grizzly bar structure that is arranged in parallel in the horizontal direction dorsad, arranged bigger angle section interval of grid strip when being used for solids-laden system, thereby prevented the accumulation of solid particle on the plate face effectively, even solid content also can steady in a long-term be operated up to 20% in the liquid.But, thereby, cause plate efficiency low in middle part, gap generation gas phase short-circuit flow because the angle section spacing is bigger.Certain industrial tower measured data is shown the gas phase murphree efficiency of flow through type individual layer plane angular tower plate can be low to moderate below 10%, has seriously reduced the separating effect of tower, the economic performance of equipment and process is worsened.
Summary of the invention
The purpose of this utility model provides a kind of flow through type multi-step angular tower plate.
The gas-liquid contact element of flow through type multi-step angular tower plate is made of angle section, and has the sandwich construction of doing orderly arrangement in the horizontal and vertical directions.
The utility model has the advantages that:
1) column plate does not have straight-through gas phase channel, when gas, liquid when mobile, must form mutual percolation state, effectively prevented the gas phase short circuit phenomenon, increased the pairing interphase mass transfer area of unit tower height, improved plate efficiency.
2) column plate does not have horizontal plane and concave surface upwards, is difficult for taking place the accumulation of solid particle, is applicable to gas (vapour)---the unit processes such as absorption, distillation, stripping and the chemical reaction of liquid system that contain solid particle.
3) tower plate structure is simple, and good rigidity is cheap for manufacturing cost, and is easy to installation and maintenance.
Description of drawings
Fig. 1 is the structural representation of flow through type multi-step angular tower plate;
Fig. 2 is the working state schematic representation of flow through type multi-step angular tower plate.
The specific embodiment
Flow through type multi-step angular tower plate is made of the angle section of arranging in order on level and vertical both direction, and Fig. 1 is the structural representation of three layers of angular tower plate.Adopt equilateral angle section section bar, the angle section rib is gone up dorsad and is settled.Angle section on the same horizontal plane is arranged in parallel, and distance between axles is generally 1.2～3 times of angle section width in the angle section.The position parallel misalignment of neighbouring two-layer angle section is arranged, and promptly the upper strata angle section just in time shelters from the horizontal clearance between lower floor's angle section, constitutes step structure.The vertical interval of neighbouring two-layer angle section horizontal plane can be regulated as required, is generally 1.2～3 times of angle section width.The angle section number of plies on the vertical direction also can design as required, is generally 2～4 layers.The material of angle section adopts carbon steel, stainless steel, aluminium alloy, plastics, fiberglass, enamel or by its composite that constitutes.
Have said structure column plate duty as shown in Figure 2, when gas phase makes progress, when liquid phase flows downwards in opposite directions, must between neighbouring two-layer angle section, form mutual percolation state, effectively prevented the gas phase short-circuit flow, increase the pairing interphase mass transfer area of unit tower height, thereby improved plate efficiency.
Embodiment:
Be applicable to that internal diameter is the tower of 600mm, make three layers of compound flow through type angular tower plate with the angle section of 20 * 20 * 3mm, the horizontal centre-to-centre spacing of angle section is 42mm, vertical centre distance between two-layer up and down angle section is 28mm, the bottom backbar is with the angle section of 30 * 30 * 4mm, and the interlayer backbar is with the angle section of 20 * 20 * 3mm.Distance between plates between two adjacent groups multilayer angular tower plate is 300mm, and the horizontal direction of the angle section of two groups of column plates is the right angle each other.Be used to contain water slurry---the air system of 20% (weight) calcium carbonate granule (average grain diameter 100 μ m), stable operation does not have the clogging of accumulation.
