The absorption tower is connected with a converter through a surface cooling pipe, the surface cooling pipe comprises a vertical ascending section and a vertical descending section, and the ascending section is connected with the descending section through an arc section. The traditional equipment is assisted, and the effect of reducing the temperature of sulfuric acid in the circulating acid tank is realized. Thereby realizing the effect of ensuring the quality of the sulfuric acid product.
Description
Technical Field
The utility model relates to the field of sulfuric acid dry absorption, in particular to a dry absorption section device for reducing the temperature of sulfuric acid in a circulating acid tank.
Background
Flue gas enters a purification, conversion and dry absorption section for acid production after passing through a bag-type dust collector, 93 percent or 98 percent concentrated sulfuric acid is produced, but the flue gas temperature is too high due to changes of ore feeding amount and process conditions in the process, the temperature of dry acid and acid absorption is very high, and all heat cannot be taken away only by cooling a circulating acid tank by a plate-type heat exchanger, so that qualified sulfuric acid products cannot be produced.
Disclosure of Invention
The utility model discloses a dry-suction workshop section device for reducing the temperature of sulfuric acid in a circulating acid tank, which assists traditional equipment and realizes the effect of reducing the temperature of the sulfuric acid in the circulating acid tank. Thereby realizing the effect of ensuring the quality of the sulfuric acid product.
In order to realize the technical effect, the application discloses dry-absorption workshop section device for reducing sulfuric acid temperature in a circulating acid tank, including the first absorption tower that is connected with the circulating acid tank, first absorption tower passes through the cold union coupling of table with the converter, the cold pipe of table includes vertically ascending section and descending segment, ascending section and descending segment pass through the segmental arc and link to each other.
Furthermore, the ascending section, the descending section and the arc-shaped section are all tubular structures with circular sections, and the diameters of the sections are the same.
Furthermore, a spray head is arranged at the upper part of the first absorption tower, an acid outlet is arranged at the bottom of the first absorption tower, the spray head is connected with an outlet of the circulating acid tank, and the acid outlet is connected with an inlet of the circulating acid tank.
Furthermore, the meter cooling pipes are arranged in one or more numbers, and the meter cooling pipes are connected in series or in parallel.
Further, the surface cooling pipe is an iron pipe.
The beneficial effects of the utility model include:
through set up the cold pipe of table between converter and first order absorption tower, realize the natural heat dissipation through the cold pipe of table, cool down the flue gas in advance, reduce the temperature of flue gas, thereby reduce the temperature of flue gas when getting into the one-level absorption tower, the temperature that has reduced the circulation acid is more favorable to producing qualified sour product, the cold pipe simple manufacture of above-mentioned table, it is simple and convenient to change the step on the basis of former equipment, and later stage production need not management and maintenance, and does not consume the energy of electric energy or other forms.
