Abstract
The utility model provides an acid return port device at the bottom of a sulfuric acid drying tower, which comprises a tower body, wherein a sleeve is arranged outside an acid return port at the lower end of the tower body, an acid return pipe is arranged at the lower end of the sleeve, the sleeve is connected with the acid return pipe through a flange, an anti-corrosion acid-resistant brick is lined on the lower part of the tower body, a gap is arranged between the sleeve and the acid return port, anti-corrosion slurry is filled in the gap, and an acid discharge port is arranged in the middle of the sleeve. According to the utility model, the anti-corrosion masonry is carried out again at the conical bottom of the drying tower, the acid discharge port is additionally arranged at the gap between the sleeve and the acid return port, a small amount of acid liquid which is corroded and leaked by the acid return port at the upper part of the acid discharge port flows out from the acid discharge port, anti-corrosion slurry is filled into the gap from the acid discharge port, so that sulfuric acid is prevented from being stored at the gap close to the flange, the problem of acid leakage at the sleeve flange of the acid return port at the bottom of the drying tower is solved, and the production cost is greatly reduced.
Description
Technical Field
The utility model belongs to the technical field of metallurgical equipment, and particularly relates to an acid return port device at the bottom of a sulfuric acid drying tower.
Background
In sulfuric acid production, SO-containing 2 The flue gas enters a drying tower, is dried by sulfuric acid and then enters a conversion system, and the converted SO-containing flue gas contains SO 3 The flue gas is absorbed in the drying tower, and sulfuric acid after absorption is returned to the circulating acid tank from the acid return port at the bottom of the drying tower. The acid return port at the bottom of the existing drying tower is directly sleeved with a sleeve, and is connected with a pipeline of the acid return tank through a flange. Acid corrosion causes that a small amount of acid flows into the gap between the sleeve and the acid return port, so that acid leakage is caused at the flange, and the acid leakage phenomenon still exists at the flange within a period of time after each maintenance.
Disclosure of Invention
The utility model provides an acid return port device at the bottom of a sulfuric acid drying tower for solving the problems.
The technical scheme of the utility model is realized as follows: the utility model provides an acid mouth device returns in sulphuric acid drying tower bottom, includes the tower body, the outside sleeve pipe that is equipped with of acid mouth is returned to the tower body lower extreme, the sleeve pipe lower extreme is equipped with back sour pipe, pass through flange joint between sleeve pipe and the sour pipe that returns, tower body lower part inside lining is equipped with anticorrosive resistant sour brick, be equipped with the gap between sleeve pipe and the acid mouth that returns, the anticorrosive mud of gap intussuseption packing, sleeve pipe intermediate position is equipped with acid outlet.
The beneficial effects of the utility model are as follows: according to the utility model, the anti-corrosion masonry is carried out again at the conical bottom of the drying tower, the acid discharge port is additionally arranged at the gap between the sleeve and the acid return port, a small amount of acid liquid which is corroded and leaked by the acid return port at the upper part of the acid discharge port flows out from the acid discharge port, anti-corrosion slurry is filled into the gap from the acid discharge port, so that sulfuric acid is prevented from being stored at the gap close to the flange, the problem of acid leakage at the sleeve flange of the acid return port at the bottom of the drying tower is solved, and the production cost is greatly reduced.
