Abstract
The utility model relates to an acid and alkali-resistant absorbing tower which comprises a shell, wherein the shell is of a dual-layer structure, a chlorinated polyvinyl chloride layer is used as the inner layer of the shell, a glass fiber reinforced plastic is used as the outer layer of the shell, a gas outlet is formed in the top of the shell, a slurry tank is arranged at the bottom of a cavity inside the shell, a discharging hole is formed in the slurry tank, a gas inlet is formed above the slurry tank, and a filler layer and a spraying device are arranged above the gas inlet. The acid and alkali-resistant absorbing tower is simple in machining process, and convenient in operation; the shell has the advantages of high strength, high temperature resistance and strong acid and strong alkali resistance due to the adoption of the dual-layer structure of the inner layer and the outer layer; and the acid and alkali-resistant absorbing tower is thorough in absorbing.
Description
Technical field
The utility model relates to the absorption tower of generally using in the petroleum and petrochemical industry, what be specifically related to is a kind of absorption tower of acid-fast alkali-proof.
Background technology
The absorption tower is the equipment of realizing absorption operation, and absorbent adds mobile from top to bottom with cat head, contact with the gas that flows from bottom to top, and the liquid that has absorbed absorbent is discharged at the bottom of tower, and purified gas is discharged from cat head.Existing absorption tower includes shell, its shell is one deck, the technique of making shell is complicated, and the poor-performing of material itself, so that this absorption tower intensity difference, ability high temperature resistant and strong alkali-acid resistance is low, when the material that number acid alkalescence is stronger leaves in the tower, corrosion is caused on the absorption tower, thereby reduced the service life on absorption tower.
Summary of the invention
The purpose of this utility model provides a kind of absorption tower of acid-fast alkali-proof, and the absorption tower of this acid-fast alkali-proof is used for solving the low problem of ability of existing absorption tower strong alkali-acid resistance.
The technical scheme that its technical problem that solves the utility model adopts is: the absorption tower of this acid-fast alkali-proof comprises housing, and housing is double-deck, and wherein internal layer is the chliorinated polyvinyl chloride layer, and skin is fiberglass; Case top is provided with gas vent, and the enclosure interior cavity bottom is slurry pool, and slurry pool has leakage fluid dram, and the slurry pool top is provided with gas feed, and the gas feed top is provided with packing layer and spray equipment.
Slurry pool is connected with spray equipment by pipeline and circulating pump in the such scheme.
The utlity model has following beneficial effect:
1, housing of the present utility model is double-deck, internal layer adopts the haloflex of extruding by squeezing the pipe production line, processing technology is simple, easy to operate, skin is fiberglass, interior outer double-layer structure like this makes housing have high strength, and the advantage of high temperature resistant and strong alkali-acid resistance has prolonged service life.
2, the utility model absorbs thoroughly, is widely used in the polytype gas cleaning.
Description of drawings
Fig. 1 is structural representation of the present utility model.
1 internal layer, 2 outer 3 gas vents, 4 slurry pools, 5 leakage fluid drams, 6 gas feeds, 7 packing layers, 8 spray equipments, 9 circulating pumps.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1, the absorption tower of this acid-fast alkali-proof comprises housing, housing is double-deck, wherein internal layer 1 is the chliorinated polyvinyl chloride layer, outer 2 is fiberglass, chliorinated polyvinyl chloride is model engineering plastic, it is a kind of new material with high strength, high temperature resistant, strong alkali-acid resistance, like this so that the absorption tower can prevent effectively that in use some strong acid and strong base materials are to the corrosion of tower, so that the operating efficiency on absorption tower improves greatly, in addition, chliorinated polyvinyl chloride is outward fiberglass, makes the intensity on absorption tower better; Case top is provided with gas vent 3, and the enclosure interior cavity bottom is slurry pool 4, and slurry pool 4 has leakage fluid dram 5, before the utility model work, at first is mixed with different slurries according to the harmful components in the flue gas, and slurries are placed in the slurry pool 4; Slurry pool 4 tops are provided with gas feed 6, and gas feed 6 tops are provided with packing layer 7 and spray equipment 8, and packing layer 7 is the hollow ball packing layer.Slurry pool 4 is connected with spray equipment 8 by pipeline and circulating pump 9, and circulating pump 9 is required to be noncorrosive pump.
The flue gas that contains harmful components enters from gas feed 6, motion from bottom to top in the absorption tower, during through spray equipment 8 and packing layer 7, in the spray equipment 8 spray and under slurries the harmful components in the flue gas are removed, because through containing the packing layer 7 of hollow ball, the contact area of flue gas and slurries increases, and improves the efficient of vapour-liquid mass, discharges from the gas vent 3 at top, absorption tower at last through purified gas.Slurries are got back to again slurry pool 4 after spray equipment 8 sprays, can reuse, and have reduced the discharging of waste liquid, and slurries can also be discharged from the absorption tower by leakage fluid dram 5.
Claims (2)
1. the absorption tower of an acid-fast alkali-proof, it is characterized in that: the absorption tower of this acid-fast alkali-proof comprises housing, and housing is double-deck, and wherein internal layer (1) be the chliorinated polyvinyl chloride layer, and skin (2) is fiberglass; Case top is provided with gas vent (3), the enclosure interior cavity bottom is slurry pool (4), slurry pool (4) has leakage fluid dram (5), slurry pool (4) top is provided with gas feed (6), and gas feed (6) top is provided with packing layer (7) and spray equipment (8).
