Description
Technical field
The utility model belongs to the chemical industry desulphurization plant, more particularly relates to a kind of design and improvement of wet desulfuration tower.
Background technology
Over past ten years, for effectively reducing SO in the flue gas
2Discharging, developed liquid spraying and absorbed desulphurization plants such as desulfurizing tower, venturi string moisture film tower, rotating stream tray scrubber and rectangle swash plate tower.These equipment all are external mature technology equipment, do not have technology property right problem.Liquid spraying absorption tower resistive connection dirt performance is good, the about 500Pa of resistance drop, but desulfuration efficiency only about 60%, the about 1L/m of the liquid-gas ratio of sweetening process
3The desulfuration efficiency about 70% of venturi string moisture film tower, the about 0.3L/m of liquid-gas ratio
3, because throat gas speed is up to 70m/s, the equipment pressure drop reaches 3000Pa, the energy consumption height; Rotating stream tray scrubber belongs to the equipment that Gas-Liquid Absorption and gas-liquid separation are combined, and has gas-liquid separation effect preferably, but desulfuration efficiency is less than 50%, thereby rotating stream tray scrubber is more suitable as gas-liquid separation equipment; The built-in swash plate of rectangle swash plate tower, gas liquid cross-flow contact twice, equipment pressure drop be less than 500Pa, but desulfuration efficiency is less than 60%, and the liquid-gas ratio of sweetening process is greater than 1L/m
3
Contrast as can be seen by the desulfurized effect to above-mentioned desulphurization plant: the desulfurized effect of venturi string moisture film tower is better, and its liquid-gas ratio is 0.3L/m only
3, but pressure drop reaches 3000Pa.
Summary of the invention
Technical problem to be solved in the utility model overcomes the defective that traditional desulphurization plant liquid-gas ratio is big, desulfuration efficiency is low exactly, provides that a kind of gas-liquid separation effect is good, desulfuration efficiency is high, liquid-gas ratio is littler, and the low wet desulfuration tower of pressure drop.
In order to solve the problems of the technologies described above the tower tray that the utility model comprises tower body, is positioned at air inlet, gas outlet, inlet and the liquid outlet on the tower body and is positioned at tower body.Tower body is square column tower or cylinder tower, and air inlet is positioned at the tower body lower side, and inlet is positioned at the tower body upper side, and the gas outlet is positioned at the tower body center of top, and liquid outlet is positioned at the tower body bottom center.Tower tray has multilayer, and every layer of tower tray comprises that a plurality of injection spinning liquid assembly monomers connect successively.Spray spinning liquid assembly monomer and comprise feed liquor reducing plate, air inlet reducing plate, median septum between feed liquor reducing plate and air inlet reducing plate, be connected to the feed liquor enlarging plate and the air inlet enlarging plate of feed liquor reducing plate and air inlet reducing plate upper end, be connected the outer panel of feed liquor enlarging plate upper end, be connected the interior plate of air inlet enlarging plate upper end, be connected the movable flow device of outer panel upper end and be installed in above-mentioned feed liquor reducing plate, air inlet reducing plate, median septum, feed liquor enlarging plate, air inlet enlarging plate, the end socket at outer panel and interior plate two ends.Feed liquor reducing plate and median septum constitute the feed liquor reducing, and air inlet reducing plate and median septum constitute the air inlet reducing, and inlet is connected with the feed liquor reducing of spraying spinning liquid assembly monomer.
Tower tray has 2～4 layers, and the fluid on upper strata is mixed the feed liquor reducing connection of mouth and lower floor between the adjacent two layers.
Every layer of tower tray comprises that 8～12 are sprayed spinning liquid assembly monomer, and the air inlet reducing plate of previous injection spinning liquid assembly monomer is connected with the next median septum that sprays spinning liquid assembly monomer.
This equipment organically combines a plurality of similar venturi ejection assemblies and cyclone hydraulic separators on one deck tower tray, finishes gas-liquid mixed fast and absorbs and gas-liquid separation.
According to the principle that venturi sprays, utilize the rising flue gas to be used as power, in the injection channel of slit-shaped, finish imbibition and gas-liquid mixed.At the slit place, less gas speed can drive liquid and move upward, and gas-liquid mixed is more abundant in the zonule, thereby the pressure drop of this equipment is low, is lower than 600Pa, and desulfurized effect is good, and the single-stage desulfuration efficiency is up to 75%.
The top of injection channel is connected with the semi-circular cyclone hydraulic separators of opening, because the difference of gas-liquid proportion is bigger, the difference of the centrifugal force that is produced is more obvious, make liquid be back to the tower tray bottom along the tangential direction of cyclone hydraulic separators outer edge, gas then baffling upwards passes through the last layer tower tray, thereby finishes the separation of gas-liquid.
Be similar to the Venturi tube structure miniaturization, on the one-level tower tray, can be arranged in parallel ten rows, even more spray the spinning liquid assembly.Gas enters the last layer tower tray by after spraying the spinning liquid assembly, and liquid is under the guide effect of cyclone hydraulic separators outer edge, turns back to the injection liquid that can be used as adjacent assemblies behind the tower tray.Like this, liquid can repetitive cycling use ten times on one deck tower tray, even more.After liquid is circulated to the afterbody assembly, just can enter down one deck tower tray.The liquid-gas ratio that sprays the spinning liquid tower tray only is 10% of a legacy equipment, can be lower than 0.1L/m
3, thereby can reduce the absorption liquid measure significantly, and then reduce the power consumption of carrying liquid.
The utility model has overcome the defective that traditional desulphurization plant liquid-gas ratio is big, desulfuration efficiency is low, provides that a kind of gas-liquid separation effect is good, desulfuration efficiency is high, liquid-gas ratio is littler, and the low wet desulfuration tower of pressure drop.It utilizes the rising flue gas to be used as power according to the principle that venturi sprays, and finishes imbibition and gas-liquid mixed in the injection channel of slit-shaped.At the slit place, less gas speed can drive liquid and move upward, and gas-liquid mixed is more abundant in the zonule.Thereby this installs that not only gas-liquid separation effect is good, desulfuration efficiency is high, liquid-gas ratio is littler, and pressure drop is low.The single-stage desulfuration efficiency is up to 75%, and total desulfurized effect can reach 90%, and pressure drop is less than 1500Pa.It can be widely used in SO in the flue gas
