Description
Technical field
This utility model relates to dehydrater, is specifically related to a kind of spiral-flow type dehydrater.
Background technology
Boiler, sintering machine and the pelletizing equipment built in early days, its emission-control equipment requires relatively low due to sulfur dioxide emissioning concentration.Waste gas treatment process is generally dry method, semidry process desulfurizer, sometimes even without desulfurizer.The smog discharge temperature of these sulfur removal technologies is higher, less to the corrosivity of former construction concrete chimney and flue, so the concrete chimney built in early days and flue inner wall are almost without doing preservative treatment.Along with the enforcement of " fossil-fuel power plant atmospheric pollutant emission standard " (GB13223-2011), various places are all performing the environmental requirement of minimum discharge, the substantial amounts of application that the higher wet desulfurizing process of desulfuration efficiency obtains.In wet desulfurizing process, the exhaust temperature of neat stress is typically at about 50 DEG C, and at a temperature of this, flue gas is supersaturation flue gas, and containing substantial amounts of free water in flue gas, and this temperature is less than the acid dew-point temperature of flue gas, and corrosivity is the biggest.If concrete chimney and flue are carried out anticorrosion transformation, not only cost is the highest, and long construction period, the impact on unit is big.So more and more desulfurizing towers use the structure of the cigarette tower integration pattern integrating flue gas desulfurization and fume emission.
The desulfurizing tower of cigarette tower integration pattern is affected by structural stability, and tower top steel stack floss hole is far below the height of former concrete chimney.The environment of periphery can be caused the biggest impact after the droplet landing that neat stress is carried secretly, some designs jejune cigarette tower integrated desulfurization tower, near it as spotted.So the supersaturation free water in minimizing flue gas is the technical barrier that cigarette tower integrated desulfurization device have to overcome.
Summary of the invention
The purpose of this utility model is to overcome defect present in prior art, it is provided that a kind of spiral-flow type dehydrater, water removal effect is good.
For achieving the above object, the technical solution of the utility model there is provided a kind of spiral-flow type dehydrater, including cylindrical tower wall, it is arranged at the bracing frame bottom described tower wall, it is arranged at the edge ring flat-plate in cylinder inside described tower wall, blade assembly, the inner side of described tower wall is provided with the alloy ring flat-plate for supporting described edge ring flat-plate in annular, some dewatering orifices are offered on described alloy ring flat-plate, it is fixedly installed some limiting plates inside described tower wall, described limiting plate is close in the upper end of described edge ring flat-plate, described blade assembly includes center pipe, the two ends up and down of described center pipe are provided with shrouding, uniformly it is connected between described center pipe with described edge ring flat-plate and has some arc shaped blades, the upper surface of described arc shaped blade is by the inclined plane of edge part gradually step-down to center.
Improve further: support frame as described above is groined type.
Improve further: described center pipe and described edge ring flat-plate are made up of FRP material.
Improve further: the windward side of described arc shaped blade includes the upwardly extending segmental arc that 100mm straightway is connected with described straightway.
Improve further: described dewatering orifice is rectangular.
Improve further: the maximum spacing of adjacent described arc shaped blade is less than 200mm.
Advantage of the present utility model and having the beneficial effects that:
The flue gas utilizing the angle of blade to flow through quickly rotates to tower wall, atwirl flue gas and the inwall collision rift of steel stack, and its supersaturation water collects on inwall, and then flows into along tower along inwall, reaches the purpose except water.

Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is further described.Following example are only used for clearly illustrating the technical solution of the utility model, and can not limit protection domain of the present utility model with this.
As Figure 1-Figure 4, a kind of spiral-flow type dehydrater, including cylindrical tower wall 1, it is arranged at the bracing frame 2 bottom described tower wall 1, it is arranged at the edge ring flat-plate 3 in cylinder inside described tower wall 1, blade assembly, the inner side of described tower wall 1 is provided with the alloy ring flat-plate 4 for supporting described edge ring flat-plate 3 in annular, some dewatering orifices 5 are offered on described alloy ring flat-plate 4, some limiting plates 6 it are fixedly installed inside described tower wall 1, described limiting plate 6 is close in the upper end of described edge ring flat-plate 3, described blade assembly includes center pipe 7, the two ends up and down of described center pipe 7 are provided with shrouding 8, uniformly it is connected between described center pipe 7 with described edge ring flat-plate 3 and has some arc shaped blades 9, the upper surface of described arc shaped blade is by the inclined plane of edge part gradually step-down to center.
Spiral board dehydrater can effectively reduce the free water in flue gas.Spiral board dehydrater has the preferable suitability to high flow rate flue gas, it is smaller than bottom steel stack so being arranged in diameter, design current velocity herein is typically at 12m/s～15m/s, for preventing eddy flow dehydrater from rocking under the influence of high velocity smoke, " well " word bracing frame 2 is used to support bottom it, edge ring flat-plate 3 circumferential upper part uses limiting plate 6 at 4～6 to fix, the alloy ring flat-plate 4 of alloy material is used below edge ring flat-plate 3, alloy ring flat-plate 4 width 50mm, every piece of alloy ring flat-plate 4 arranges rectangle dewatering orifice 5(100mm*20mm), ensure that the water flowed down along tower wall 1 falls in desulfurizing tower from dewatering orifice 5.The principle of eddy flow dehydrater is that the flue gas utilizing the angle of arc shaped blade 9 to flow through quickly rotates to tower wall 1, atwirl flue gas and the inwall collision rift of steel stack, and its supersaturation water collects on inwall, and then flows into along tower along inwall, reaches the purpose except water.
Spiral-flow type dehydrater uses FRP material, and center pipe 7 is φ 500mm FRP pipe, and there are shrouding 8, pipe height 300mm in two ends, presses close to the edge ring flat-plate 3 using FRP material at tower wall 1, and edge ring flat-plate 3 height is 500mm.Connect with the arc shaped blade 9 with certain radian between edge ring flat-plate 3 and center pipe 7, arc shaped blade 9 uses special Mold Making, and its two ends height is consistent with the pipe at center and edge ring flat-plate 3 respectively, and center is low, height at tower wall 1, it is ensured that the water in flue gas can get rid of when rotated to tower wall 1.Additionally, arc shaped blade 9 has the straight section of 100mm in windward side, then with certain radian upwards, adjacent two blade maximum spacings ensure within 200mm, while ensureing water removal effect, reducing the resistance of body, arc shaped blade 9 all uses resin bonding with pipe and the edge ring flat-plate 3 at center, it is simple to site operation.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; on the premise of without departing from this utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
