Abstract
The utility model discloses a flue gas system acid absorption tower bottom filter equipment, including top cap, barrel, to be connected by the connection piece between top cap and the barrel, the top cap be the toper, division has sour aperture on top cap and the barrel. The beneficial effect of the utility model: this device has the effect that the bits of broken glass of filtering was packed, avoids the bits of broken glass to pack and blocks up the sour capillary of branch. Conical roof lid has the good upper portion acidizing fluid impact that prevents, can effectively prolong filter equipment's life.
Description
Technical field
The utility model belongs to equipment for acid making by fume field, is related to a kind of flue gas acid preparing absorption tower bottom filter device.
Background technology
During flue gas acid preparing, containing finite concentration SO2Flue gas it is purified, be dried after enter conversion procedure, in flue gas
SO2SO is converted in the presence of catalyst3, into absorption tower Jing after 98% concentrated sulfuric acid cyclic absorption output finished acid.At present,
The widely used packed tower in flue gas acid preparing absorption tower, inner stuffing are generally porcelain filler（Such as iso-saddle ring）, load in filler or raw
During product, it may appear that filler corrodes or situations such as fragmentation, broken filler is entered with the concentrated sulfuric acid in concentrated sulfuric acid cyclic process and is absorbed
The acid trap on tower top, causes a point sour capillary blockage, affects SO3, there is relieving haperacidity tail gas SO in assimilation effect3Or the index such as acid mist
Exceeded phenomenon.
Utility model content
A kind of flue gas acid preparing absorption tower bottom filter device of the purpose of this utility model, this device are rushed in high-temperature concentrated sulfuric acid
Hit, there is in corrosive environment well adapting to property and longer service life.
The technical solution of the utility model is：A kind of flue gas acid preparing absorption tower bottom filter device, including top cover, cylinder,
Connected by connection sheet between top cover and cylinder, top cover is taper, is provided with sour aperture on top cover and cylinder.
The sour aperture is arranged at equal intervals.
The sour aperture is hexagonal hole.
Top cover, cylinder, connection sheet material are 316L stainless steels.
Top cover, the wall thickness of cylinder are 3mm.
The beneficial effects of the utility model are：This device has the effect for filtering broken filler, it is to avoid broken filler is in the concentrated sulfuric acid
The acid trap on absorption tower top is entered in cyclic process with the concentrated sulfuric acid, a point sour capillary blockage is caused.Meanwhile, conical top cover has
Good anti-top acid solution percussion, can effectively extend the service life of filter.
Description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Specific embodiment
As schemed, a kind of flue gas acid preparing absorption tower bottom filter device, including top cover 1, cylinder 4, between top cover 1 and cylinder 4
Connected by connection sheet 2, top cover 1 is taper, is provided with sour aperture 3 on top cover 1 and cylinder 4.Acid aperture 3 is arranged at equal intervals thoroughly,
Circulate for acid solution.
Top cover 1, cylinder 4, connection sheet 2 are using the good 316L stainless steels of decay resistance.Top cover 1, the wall thickness of cylinder 4 are
3mm.This device has the effect for filtering broken filler, it is to avoid point sour capillary blockage.Meanwhile, conical top cover have it is good it is anti-on
Portion's acid solution percussion, can effectively extend the service life of filter.Two-piece unit formula is also convenient for installing.
