Abstract
The invention relates to a novel drying and absorption tower which comprises a tower body; an acid inlet pipe is arranged at a lateral part of the tower body and is communicated with an acid distribution pipe arranged in the tower body; a plurality of acid distribution grooves communicated with the acid distribution pipe are uniformly distributed under the acid distribution pipe; and a spray device is arranged on each acid distribution groove. The novel drying and absorption tower has the advantages as follows: 1, stacked and communicated groove and pipe type acid distribution devices are adopted, so that acid is distributed uniformly, and moreover, the spray density is large, and the using effect is better, so that the filler height can be decreased; 2, two layers of absorption towers are arranged at the internal upper part of the tower body, wherein the first absorption tower has high acid temperature, large mist amount and small mist particles, and adopts an efficient fiber demister to protect heat exchange equipment behind, and in order to ensure the emission requirement of tail gas, the second absorption tower adopts a high-speed fiber demister; and 3, a sieve plate is arranged on the path of an acid outlet pipe, a plurality of small holes which are calculated are formed in the sieve plate to ensure that all acid can pass and broken ceramic rings can be blocked, so that the quality of backflow acid can be ensured, and the tower body is prevented from being damaged.
Description
Technical field
The present invention relates to a kind of novel dry absorption tower, belong to technical field of chemical.
Background technology
It advances existing dry absorption tower sour apparatus structure form and is: each minute acid tank independently be provided with, be not communicated with mutually each other, cause each minute acid tank liquid level difference to some extent, thereby can cause that each several part divides acid inhomogeneous in the tower body, the efficient of dry absorption tower is a greater impact; And for above-mentioned reasons, in order to improve drying, absorption efficiency, packed height is higher, has increased the structure of whole dry absorption tower, awaits further improvement.
Summary of the invention
The present invention is directed to above-mentioned defective, purpose is to provide a kind of and divides acid even more, the efficient and smaller and more exquisite novel dry absorption tower of structure.
The technical scheme of the present invention's employing is for this reason: the present invention includes tower body; The tower body sidepiece is provided with acid inlet tube; Acid inlet tube is communicated with the acid distributing tube that is arranged in the tower body, is evenly equipped with some branch acid tanks that are communicated with acid distributing tube under the acid distributing tube, on each minute acid tank spray equipment is set respectively.
Filler is established in said spray equipment below.
The bar arch is established in said filler below, and the percent opening of bar arch is greater than 80%.
Said gas outlet is arranged on tower body top, between acid distributing tube and gas outlet, is provided with two-layer fiber mist eliminator successively.
Saidly go out acid tube and be arranged on the tower body bottom, go out the acid tube path and be provided with sieve plate, offer aperture on the sieve plate.
The present invention: 1) adopt stack UNICOM trough-pipe type acid trap, acid is evenly distributed, and sprinkle density is big, result of use is better, therefore can reduce packed height; 2) the present invention establishes two layer absorption towers at the tower body internal upper part; First absorption tower is the heat transmission equipment of protection back because the acid temperature is high, the mist amount is big, droplet is thin, adopts the high-efficiency fiber demister; For guaranteeing the requirement of exhaust emissions, the high speed fiber mist eliminator is adopted on second absorption tower; 3) the present invention is going out on the path of acid tube to be provided with sieve plate, offers the some apertures through calculating on the sieve plate, measures ability all-pass mistake to guarantee acid, but can intercept broken porcelain ring, avoids damage with the quality and the protection tower body of protection returned acid; 4) adopt the stainless steel strip of large opening rate to encircle, make smoke distribution more even, the tower resistance is littler, simultaneously the also corresponding weight that reduces tower.

Fig. 3 is the C-C view of Fig. 1.
1 is that top fiber demister, 2 is that lower floor's fiber mist eliminator, 3 is that acid distributing tube, 4 is that filler, 6 is that bar encircles for dividing acid tank, 5 among the figure.
The specific embodiment
The present invention includes tower body, the tower body sidepiece is provided with acid inlet tube, and acid inlet tube is communicated with the acid distributing tube 3 that is arranged in the tower body, and acid distributing tube is evenly equipped with some branch acid tanks 4 that are communicated with acid distributing tube 3 for 3 times, on each minute acid tank 4 spray equipment is set respectively.
Filler 5 is established in said spray equipment below, and bar arch 6 is established in filler 5 belows, and the percent opening of bar arch 6 is greater than 80%; The gas outlet is arranged on tower body top, between acid distributing tube 3 and gas outlet, is provided with top fiber demister 1 and lower floor's fiber mist eliminator 2 successively; Go out acid tube and be arranged on the tower body bottom, go out the acid tube path and be provided with sieve plate, offer aperture on the sieve plate.
Tower body is a vertical and cylindrical liner acidproof brick, and the inner-tower filling material supporting adopts the porcelain ball bar arch 6 of large span, large opening rate to support, and top repaves the grid brick.Huddle on the grid brick and highly be the ￠ 76mm cascade ring acid resistant porcelain filler of 2500mm.Filler top is acid separating device.Drying tower top is provided with drawer type woven wire Despumation device, to collect the sour foam in the gas.First absorption tower is the heat transmission equipment of protection back because the acid temperature is high, the mist amount is big, droplet is thin, adopts the high-efficiency fiber demister.For guaranteeing the requirement of exhaust emissions, the high speed fiber mist eliminator is adopted on second absorption tower.
