Description
Technical field
The utility model relates to gas-liquid separation technical field, the demister blade that especially a kind of demister uses.
Background technology
Demister is widely used in the drop that gas in knockout tower is carried secretly, effectively can remove droplet, Chinese invention patent 201410377552.4 discloses a kind of demister of many curved strip hook blade, it is characterized in that, comprise at least 2 demister modules, a tank is provided with between every 2 demister modules levels, each demister modules comprises at least 2 the many curved strip hook blades and draw-in groove that are parallel to each other, be fixedly connected with by draw-in groove between the hook of curved strip more than at least 2 blade, the wavy surface of each many curved strip hook blade is provided with a hook.Foregoing invention is only provided with hook on wavy surface, and therefore limited to the barrier effect of droplet, demisting efficiency is not high.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and provide a kind of demister blade, add the hook that can improve demisting efficiency, and be optimized hook position, make the intensity not only increasing blade, demisting efficiency also improves greatly.
In order to realize this object, the utility model adopts following technical scheme: a kind of demister blade, comprise body curved more than one and the installation portion being positioned at the upper and lower two ends of body, the cross section of described body is waveform, comprise at least one crest and/or trough, be provided with hook above the crest of described body and/or below trough and with installation portion junction, described hook is extended to windward side by leeward side.
Further, described installation portion is the body straight section that extends to form of both sides up and down, and the surface of described straight section is provided with positioning convex.
Further, described body comprises a crest and a trough, and described adjacent hooks is arranged on the not homonymy of body, and forms one just to the opening in inlet air flow direction with body.
Further, described installation portion is provided with installing hole in one end of length direction, and described installing hole is at least two, and close to installation portion edge.
Further, described positioning convex comprises the hemisphere jut being positioned at straight section centre position and the half arc plush copper being positioned at straight section top.
Further, the thickness of described body is between 0.5-5mm.
After adopting technical scheme described in the utility model, bring following beneficial effect:
1, be provided with hook at the body of demister blade and installation portion junction, increase the chance of flue gas at air inlet and gas outlet place and blade making contact, demisting efficiency is improved.
2, effectively enhance the intensity of demister blade, demister blade can be manufactured longer, larger, demisting efficiency improves further.
3, after installation portion increases positioning convex, make the installation of blade more firm.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
As shown in Figure 1 to Figure 3, a kind of demister blade, comprise body 1 curved more than one and the installation portion 2 being positioned at body about 1 two ends, installation portion 2 is extended to form both sides up and down by body 1, it is a straight section, both junctions are excessive by circular arc, and the development length of straight section is preferably between 10-30mm, and its surface is provided with positioning convex.The cross section of described body 1 is waveform, comprises at least one crest and/or trough, is provided with hook 3 above the crest of body 1 and/or below trough and with installation portion 2 junction, and described hook 3 is extended to windward side by leeward side.
Embodiment one
As depicted in figs. 1 and 2, body 1 is for having the corrugated sheet of a crest, its upper and lower two ends vertically extend to form straight section, hook 3 is provided with on the upside of crest, hook 3 is extended to windward side by leeward side, and and form one between body 1 just to the opening in inlet air flow direction, for stopping the droplet in inlet air flow, in the junction of body 1 with straight section, and the side contrary with crest place hook 3 is also provided with hook 3, preferably with crest place hook 3 homonymy and its rear is also provided with a hook 3, described hook 3 opening direction and the reverse setting of flue gas stream.
Be provided with installing hole 6 in one end of installation portion 2 length direction, installing hole 6 is distributed in the upside of installation portion 2, and close to installation portion 2 edge, preferred installing hole 6 quantity is 2, and installing hole 6 is connected with bracing or strutting arrangement for during fixing demister blade.
Be provided with described positioning convex at straight section, comprise the hemisphere jut 4 being positioned at straight section centre position and the half arc plush copper 5 being positioned at straight section top, described hemisphere jut 4 and half arc plush copper 5 can cooperatively interact when mounted and play the effect of clamping and positioning.
Preferably, the thickness of described body 1 is between 0.5-5mm, and the thickness of hook 3 is identical with body 2, and narrows in edge, and its material can select any one in engineering plastics, aluminium alloy or stainless steel material.
Embodiment two
As shown in Figure 3, the present embodiment and the difference of embodiment one are that the shape of described body 1 is different, and its installation portion 2 structure is identical with embodiment one, does not describe at this.Body 1 in the present embodiment, comprises a crest and a trough, and described adjacent hooks 3 is arranged on the not homonymy of body 1, and forms one just to the opening in inlet air flow direction with body 1, for stopping the droplet in inlet air flow.Owing to adding the quantity of crest or trough, too increase the quantity of hook 3, make the contact of flue gas and demister blade more abundant, demisting efficiency improves further, except fog effect is more desirable simultaneously.
Embodiment three
As shown in Figure 4, the difference of the present embodiment and embodiment one is, with the junction of straight section on rear side of the crest of body 1, and the side contrary with crest place hook 3 is provided with a hook 3, described hook 3 opening direction and the reverse setting of flue gas stream.The blade construction of the present embodiment is more simple, can reduce production cost, to meet different instructions for uses.
The above is embodiment of the present utility model, it should be pointed out that for the ordinary skill in the art, and not departing under the utility model principle prerequisite, can also make various deformation and improvement, this also should be considered as protection domain of the present utility model.
