Abstract
The utility model relates to a high-speed three-dimensional mass-transfer tower plate with super-large air flow. A plurality of caps are arranged on the tower plate, a separating cover is arranged outside the caps, and an inlet is provided with a liquid down-flow pipe while an outlet is provided with a down-flow weir. The top of each cap is provided with an opening which has a form of a cyclone shutter, and the opening rate of the cap is larger than that of the tower plate.
Description
One, technical field
The utility model relates to a kind of high speed combined trapezoid spray tray of super large tolerance, belongs to chemical machinery field.
Two, background technology
In petrochemical industry, industrial departments such as petroleum refining, chemical industry, light industry, environmental protection, medicine and atomic energy, column plate and filler are widely used in unit processes in chemical synthesis such as distillation, absorption, extraction, absorption, washing, cooling.Advantages such as filler has the separative efficiency height, and pressure drop is little, and disposal ability is big, but cost is bigger, and operating flexibility is little, supporting tower internals is required high; Operating flexibility of tray is big, the anti-obstruction, and cost is low, and separative efficiency is relatively large, but pressure drop will be bigger, and disposal ability is lower.Under the gas liquid ratio of routine, column plate and filler all can satisfy the needs of commercial Application, but for some special operating modes, need the tower internals of some special constructions to meet the needs of production, as high liquid-gas ratio (stripping section), ultralow liquid-gas ratio (as absorption tower, washing deentrainment tower), high liquid residence time (as reaction fractionating tower, biochemical reaction tower).Operating mode for super large tolerance such as flue gas desulfurization, ethylene quenching tower, coking fractional distillation column, synthesis gas liquid desulfurization and decarburization towers, tower diameter is excessive on the one hand causes equipment investment sharply to strengthen, liquid flowing strength is low excessively under rational liquid-gas ratio on the other hand, column plate plate face difficult arrangement, the increasing liquid flowing strength that is compelled against one's will causes separating energy consumption to increase.Existing in addition tower internals, void tower operating gas velocity only about 1m/s, space utilization deficiency in the tower, the expansion amount that significantly improves disposal ability is transformed difficulty.
Three, summary of the invention
The purpose of this utility model just provides a kind of high speed combined trapezoid spray tray of super large tolerance, and it mainly is made up of column plate, calotte, separation hood, downspout, downflow weir, calotte hole, central tube, air rising hole etc.Column plate has a plurality of air rising holes, and top, hole is equipped with calotte, and the calotte outside is provided with separation hood, and arrival end has downspout, and the port of export is provided with downflow weir.The air rising hole form is flat hole or splayed, and percent opening accounts for 6%～50% of column plate cross section.Calotte (2) is that 3～10mm or calotte bottom have liquid inflow port of the same area with column plate (1) crack spacing; Calotte and separation hood crack spacing are 10～50mm; The calotte upper top has the calotte hole, and open-cellular form is the eddy flow shutter, and percent opening is greater than the percent opening of column plate.Separation hood is that individual layer or bilayer revolve tube.
High 50～the 500mm of height of weir plate, downspout aspect ratio overflow height of weir 200～600mm.
