Abstract
The utility model discloses a desulfurization tower which comprises a cylinder, wherein a support grid plate is mounted in the cylinder; multiple layers of grid filler plates are arranged above the support grid plate; the grid filler plates in the adjacent upper and lower layers rotate for 45 degrees relative to each other; the space between every two layers of the multiple layers of grid filler plates is gradually reduced from bottom to top; a slotted disc type liquid distributor is arranged above the grid filler plates; and a lower-opening type gas distributor is arranged below the support grid plate. According to the desulfurization tower disclosed by the utility model, the space between every two layers of the grid filler plates is gradually reduced from bottom to top, the gas H2S concentration and the driving force are gradually reduced, and the optimal operation is guaranteed; the liquid distributor is a slotted disc type liquid distributor while the gas distributor is a lower-opening type gas distributor; the gas-liquid distribution is uniform; and the slotted disc type liquid distributor maintains a certain liquid level in the slot, and even in the case of some deviation in the mounting process, the liquid in the slot is uniformly distributed due to the height of the liquid level.
Description
Technical field
The utility model relates to technical field of chemical, relates in particular to a kind of desulfurizing tower.
Background technology
Former semiwater gas desulphurizing tower adopts random packing (φ 76, φ 50PP cascade ring), and desulfuration efficiency is low, semiwater gas import H2S 1g/Nm
3, outlet H2 S 100mg/Nm., desulfurizing tower resistance 26mmHg, so desulfuration efficiency is low, resistance is large.Partly take off the obstruction of tower sulphur cream and often clean, can not guarantee normal production, especially output increases, desulfurizing tower is DN6000, if large tower is selected random packing, gas more easily produces bias current, the gas-liquid skewness, more stifled tower, can not guarantee stable normal production of long period.
The utility model content
The utility model purpose is exactly in order to make up the defective of prior art, to provide a kind of gas-liquid contact good desulfurizing tower.
The utility model is achieved through the following technical solutions:
A kind of desulfurizing tower, include cylindrical shell, the support screen is installed in described cylindrical shell, described support screen top is provided with multilayer grid filler plate, wherein the two-layer grid packing plate in adjacent up and down is 45 degree rotations, air-flow and the counter-rotating of liquid stream in whole tower, the mobile contact liq of eddy flow descends along filling surface by gravity, form liquid film at filling surface and present membranaceous flowing downward, gas flows and the liquid film contact mass transfer from bottom to top as continuous phase, forms between gas-liquid to drip or the film contact, along with gas speed increases, liquid drop from top to bottom attenuates, and gas-liquid contact is good; The every spacing between two-layer of multilayer grid filler plate is arrogant from top to bottom to be reduced gradually, is provided with trough-tray liquid distributor above the grid packing plate, is provided with under shed formula gas distributor below described support screen.
The side of described trough-tray liquid distributor is provided with the spout hole of differing heights, and the spout hole height can be regulated the flow of doctor solution.
The utility model has the advantages that: the every spacing between two-layer of grid packing plate of the present utility model is arrogant from top to bottom to be reduced gradually, gas H2S concentration and motive force reduce gradually from height, guarantee optimum operation, liquid distribution trough is selected trough-tray liquid distributor, gas is selected under shed formula gas distributor, uniform gas-liquid distribution, and trough-tray liquid distributor is to keep certain liquid level in groove, even in a little deviations of installation process, the height of liquid level also makes uniform liquid distribution in groove.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
as shown in Figure 1, a kind of desulfurizing tower, include cylindrical shell 1, be equipped with in described cylindrical shell 1 and support screen 2, described support screen 2 tops are provided with multilayer grid filler plate 3, wherein the two-layer grid packing plate 3 in adjacent up and down is 45 degree rotations, air-flow and the counter-rotating of liquid stream in whole tower, the mobile contact liq of eddy flow descends along filling surface by gravity, form liquid film at filling surface and present membranaceous flowing downward, gas flows and the liquid film contact mass transfer from bottom to top as continuous phase, form between gas-liquid and drip or the film contact, along with gas speed increases, liquid drop from top to bottom attenuates, gas-liquid contact is good, the every spacing between two-layer of multilayer grid filler plate 3 is arrogant from top to bottom to be reduced gradually, is provided with trough-tray liquid distributor 4 above grid packing plate 3, is provided with under shed formula gas distributor 5 below described support screen 2.
The side of described trough-tray liquid distributor 4 is provided with the spout hole of differing heights, and the spout hole height can be regulated the flow of doctor solution.
Claims (2)
1. desulfurizing tower, it is characterized in that: include cylindrical shell, the support screen is installed in described cylindrical shell, described support screen top is provided with multilayer grid filler plate, wherein the two-layer grid packing plate in adjacent up and down is 45 degree rotations, the every spacing between two-layer of multilayer grid filler plate is arrogant from top to bottom to be reduced gradually, is provided with trough-tray liquid distributor above the grid packing plate, is provided with under shed formula gas distributor below described support screen.
