Abstract
The utility model discloses an anti-splash structure for a spraying layer of a flue gas desulphurization absorption tower. The spraying layer of the absorption tower is in a multi-layer structure, the anti-splash structure is a circle of anti-splash check ring mounted on the upper side of the splash part on the side wall of the topmost spraying layer of the absorption tower, and is used for reducing flow speed of flue gas within the side wall area and preventing the splashed slurry from being brought out of the tower. The anti-splash check ring is mounted on one side of the tower body, is supported by an anti-splash check ring supporting pipe and is in a horizontally downward inclined state, and glass flakes for preventing corrosion are lined on both the surface of the anti-splash check ring and the surface of the anti-splash check ring supporting pipe. The anti-splash structure disclosed by the utility model can effectively prevent splashed slurry drops from being brought out of the tower, the conditions of scale formation on the inner wall of the tower and blockage of a defroster are greatly reduced with obvious effect, desulphurization efficiency is improved to some extent, energy is saved and consumption is reduced.
Description
Technical field
The utility model belongs to environmental protection field flue gas desulfurization technique, especially relates to the employed spraying layer antispray of the fume desulfurating absorption tower baffle ring applicable to industries such as electric power, cement, metallurgy, chemical industry.
Background technology
The limit wall nozzle of present conventional wet desulphurization absorption tower apart from the tower span from nearer (about 650-750mm), and this zone is often because resistance is less, the flue gas flow rate height, slurries drop with limit wall splash carries out tower easily, cause fouling in the tower, even cause the downstream demister to stop up, and cause the generation of gypsum rain, have a strong impact on the safe operation of desulfurizer and the environment around the facility.
Summary of the invention
The purpose of this utility model is a kind of fume desulfurating absorption tower spraying layer antispray baffle ring of design; prevent the wall flue gas escape of desulfuration absorbing tower limit, reach minimizing slurries drop and carry out tower, improve the reliability of desulfurizer; reduce the phenomenon of " gypsum rain ", realize environmental protection.
In order to realize the purpose of this utility model, take following technical scheme:
A kind of absorption tower spraying layer antispray structure, described absorption tower spraying layer is sandwich construction, described antispray structure is the circle antispray baffle ring that the splash position upside of absorption tower the superiors spraying layer limit wall is installed, and reduces wall zone, limit flue gas flow rate, and stops that the slurries that splash are carried out tower.
Described antispray baffle ring is installed in tower body one side, is supported by antispray baffle ring stay pipe, is the downward-sloping state of level, and its angle is 75 °-85 °, and length is 600-650mm, and basic and nozzle splash line intersects.
Described antispray baffle ring and antispray baffle ring stay pipe surface are by the parts that glass flake or nonmetal or alloy material are formed that are lined with that prevent its corrosion.
Technique effect of the present utility model:
1, the utility model is transformed case by reality proves, can stop effectively that the slurries drop that splashes carries out tower; Inner wall of tower fouling and demister stopping state greatly alleviate, and effect is obvious; Also reduced simultaneously gypsum rain phenomenon.
2, after the transformation, by the digital simulation analytical calculation, flow field in tower is more even, and limit wall flue gas escape situation alleviates, and has to a certain degree improved desulfuration efficiency; Energy-saving and cost-reducing.

Fig. 2 is the newly-increased spraying layer baffle ring fragmentary detail view in absorption tower.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with specific embodiment, the utility model is further described.
Fig. 1 is the newly-increased spraying layer antispray baffle ring position figure in absorption tower; As shown in the figure, the absorption tower has the multilayer spraying layer, when flue gas makes progress convection current, wall zone, limit flue gas flow rate height, the technical program is installed a circle antispray baffle ring at the splash position upside shown in the spraying layer limit wall figure of the superiors, can increase near the flue gas resistance of limit wall on the one hand, reduces wall zone, limit flue gas flow rate, play the current-sharing effect, can stop that on the other hand the slurries that splash are carried out tower.
Fig. 2 is the newly-increased spraying layer antispray baffle ring fragmentary detail view in absorption tower.The spraying layer antispray baffle ring of present technique is installed in tower body one side, is supported by antispray baffle ring stay pipe, is the slight downward-sloping state of level.Antispray baffle ring and antispray baffle ring stay pipe surface are by the parts that glass flake or nonmetal or alloy material are formed that are lined with that prevent its corrosion.
Embodiment
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect have been carried out further detailed description; institute is understood that; the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
Claims (3)
1. absorption tower spraying layer antispray structure, described absorption tower spraying layer is sandwich construction, it is characterized in that, described antispray structure is the circle antispray baffle ring that the splash position upside of absorption tower the superiors spraying layer limit wall is installed.
2. absorption tower according to claim 1 spraying layer antispray structure, it is characterized in that, described antispray baffle ring is installed in tower body one side, supported by antispray baffle ring stay pipe, be the downward-sloping state of level, its angle is 75 °-85 °, and length is 600-650mm, and basic and nozzle splash line intersects.
3. absorption tower according to claim 1 spraying layer antispray structure is characterized in that, described antispray baffle ring and antispray baffle ring stay pipe surface all be lined with prevent its corrosion be lined with glass flake or parts nonmetal or that alloy material is formed.
