Abstract
The utility model relates to a demister, which comprises a housin, be equipped with the defroster in the casing, the defroster includes the supporting component and sets up filtering component on the supporting component, be equipped with the coalescence piece in the filtering component, coalescence piece surface coating has polytetrafluoroethylene. The beneficial effects of the utility model are that: reasonable in design, simple structure, surface coating have polytetrafluoroethylene's coalescence piece can reduce gas medium in the free water taken out of to better get rid of the mist in the medium, has effectively improved and removed foam efficiency, because the defroster be two -layer, can go up lower floor's piecemeal installation coalescence piece during the installation, thus the overlap joint gap of avoiding coalescence piece piecemeal to cause leak, strengthened the coalescence effect, and the dynamic porosity is big, the pressure decrease, install easy maintenance, long service life.
Description
Technical field
The utility model relates to field of chemical equipment, is specifically related to a kind of demister.
Background technology
Demister is widely used in the enterprise's separator in the industries such as chemical industry, oil, tower manufacture, pressure vessel, it filtering can be suspended in larger liquid foam in air-flow, and energy filtering is less and minute liquid foam, thus the liquid (mist) adulterated in minimizing gas etc. are to the corrosion of equipment and pollution on the environment.And the defect such as existing demister exists that foam removal efficiency is low, voidage is little, Pressure Drop is large, complex structure, installation and maintenance inconvenience, service life are short.Therefore, a kind of new demister of design is needed badly, to solve prior art above shortcomings.
Utility model content
The purpose of this utility model is to provide a kind of demister, to overcome currently available technology above shortcomings.
The purpose of this utility model is achieved through the following technical solutions:
A kind of demister, comprise housing, be provided with demister in described housing, described demister comprises supporting component and is arranged on the filter assemblies on described supporting component, is provided with coalescent piece in described filter assemblies, and described coalescent piece of surface spraying has polytetrafluoroethylene (PTFE).
Further, described demister is two-layer.
Further, described demister thickness is 600mm.
Further, described filter assemblies is circular.
Further, silk screen is provided with in described filter assemblies.
Further, described coalescent piece of 5 quantity are 18 pieces.
The beneficial effects of the utility model are: reasonable in design, structure is simple, and surface spraying has coalescent piece of polytetrafluoroethylene (PTFE) can reduce free water in gas medium to be taken out of, thus better removes the mist in medium, effectively improve foam removal efficiency, because demister is two-layer, during installation, coalescent piece can be installed by levels piecemeal, thus the lap gap avoiding coalescent piece of piecemeal to cause leaks, enhance coalescent effect, and voidage is large, pressure reduces, and installation and maintenance are convenient, long service life.
Accompanying drawing explanation
Below in order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment below, apparently, accompanying drawing in the following describes is only some embodiments of the application, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the demister described in the utility model embodiment;
Fig. 2 is the demister structural representation front view of the demister described in the utility model embodiment;
Fig. 3 is the demister structural representation top view of the demister described in the utility model embodiment.
In figure:
1, housing; 2, demister; 3, supporting component; 4, filter assemblies; 5, coalescent piece; 6, polytetrafluoroethylene (PTFE); 7, silk screen; 8, clean medium; 9, containing mist medium.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain, all belongs to the scope of the utility model protection.
A kind of demister as Figure 1-3, comprise housing 1, demister 2 is provided with in described housing 1, described demister 2 is two-layer, and described demister 2 thickness is 600mm, and described demister 2 comprises supporting component 3 and is arranged on the filter assemblies 4 on described supporting component 3, described filter assemblies 4 is circular, be provided with coalescent piece 5 in described filter assemblies 4, described coalescent piece of 5 quantity are 18 pieces, and described coalescent piece of 5 surface sprayings have polytetrafluoroethylene (PTFE) 6.
During concrete use, when rising through filter assemblies 4 containing mist medium 9 with certain speed, due to the build-up lag effect of mist, the filament of the silk screen 7 in mist and filter assemblies 4 collides and is attached to filament surfaces.Along with the diffusion of filament surfaces mist, the gravitational settling of mist, mist forms larger drop flow to two filaments interface point along filament, because filament exists wettability, hydrophobicity, the surface tension of capillarity and liquid, cause drop is increasing, until the drop assembled arrive greatly the gravity himself produced exceed the climbing power of gas and surface tension of liquid with joint efforts time, drop is just separated from filament, thus complete its filtering and be suspended in larger liquid foam in air-flow, the process of less and minute liquid foam, obtain clean medium 8, thus the liquid (mist) adulterated in minimizing gas etc. are to the corrosion of equipment and pollution on the environment.Gas, via after demister foam removal, does not contain mist substantially.For the mist of particle diameter >=3-5um, demister is to the arresting efficiency of mist up to 98%-99.8%, and water content < 50ppm, gas only has 250-500Pa by the Pressure Drop of demister, is conducive to the production efficiency of raising equipment.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but any change is done in its shape or structure; every have identical with the application or akin technical scheme, all drops within protection domain of the present utility model.
