Description
Technical field
The utility model belongs to corrosion-proof casing technical field, is specifically related to the anti-corrosion shell based on wet cottrell
Body.
Background technology
Growing with Environmental Protection in China industry, the application of dedusting technology is more and more extensive, and wherein electric precipitation largely should
For in the mega project fume treatment such as power plant, aluminium manufacturer.With the increasingly raising of environmental requirement, country has formulated stricter
Discharge standard, the more and more higher of dedusting technology requirement, and then the requirement to dust remover component is more and more stricter, with getting over for competition
It is fiercer to come, and each deduster producer is on the basis of efficiency of dust collection is improved constantly, improvement product structure, enhance product performance and
Service life is as the Main Means for improving product competitiveness.Due to burning the combustibles such as coal, a large amount of dust-ladens can be produced, contained
The gases such as sulphur, and requirement more and more higher of the country for discharge standard, wet cottrell due to reentrainment of dust will not be produced,
And the ultra-clean draining technology of low temperature popularization and apply it is more and more.It is increasingly stricter in order to adapt to wet cottrell
It is required that anti-corrosion mode is also constantly changing, this new technique is precisely in order to adapting to the demand for development of wet cottrell and doing
The change gone out.
The flue gas composition of wet cottrell is more complicated, and body of deduster can be caused greatly containing alkaline gas containing acid
Infringement.Traditional processing mode is using attached corrosion-inhibiting coating or using stainless steel material, and corrosion-inhibiting coating is divided into anticorrosion with painting oil
Paint and glass inner-lining scale etc., easily damaged, not scratch-resistant, and a large amount of dusts contained in flue gas corrosion-inhibiting coating can be formed compared with
Macrolesion；Common stainless steel is limited for the corrosion-resisting function containing acid gas containing alkali.Simultaneously under wet type environment flue dust have compared with
Strong viscosity, simultaneously because low low-temperature flue gas easily produces dew condensation phenomenon, substantial amounts of flue dust condensation occurs in deduster, causes
Deduster operation is not smooth, accelerates corrosion rate, reduces the service life of deduster.

The beneficial effects of the utility model：
The temperature resistant range of polytetrafluoroethylene (PTFE) is larger, has reached subzero 200 DEG C 260 DEG C above freezing, in this temperature range still
With good performance, the flue gas of wet cottrell higher temperature can be well adapted to.Polytetrafluoroethylene (PTFE) will not by except
Any chemical reagents beyond extremely strong alkali are corroded, and can preferably be adapted to the flue gas environment under current various operating modes, greatly be prolonged
The service life of long deduster, reduce unit use cost.Polytetrafluorethylecoatings coatings, which have, is currently known table minimum in material
Face energy, most objects can not adhere to the yield that can reduce condensation to greatest extent thereon, simultaneously because relatively low
Coefficient of friction, the resistance inside deduster can be effectively reduced, save power consumption, reduce operating cost.Polytetrafluoroethylene (PTFE) possess compared with
Good anti-wear performance and ageing resistance, it can adapt in flue gas containing dust is more, requirement of longevity of service so that few in use
There is shut-down (breakdown) mainteance, change the situation of repairing, the reduction maintenance cost and use cost of bottom line.In the utility model simultaneously
It is automatically the hairbrush of polytetrafluoroethylene floor cleaning to disclose a kind of, and the upper of hairbrush layer is realized by motor-driven gear engagement
Lower motion, so as to reach the effect of cleaning tube wall.
