Abstract

The invention provides a corrosion-resistant desorption tower. A tower body is a barrel; a tower top is provided with an exhaust opening; a tower bottom is provided with a liquid outlet; the upper part of the tower body is provided with a liquid inlet; and the lower part of the tower body is provided with an air inlet. The corrosion-resistant desorption tower is characterized in that: the tower body is lined with a polyfluortetraethylene layer. Due to the adoption of the technical scheme, the corrosion-resistant desorption tower has the advantages and positive effects of higher corrosion resistance, long service life, higher purity of produced refined sulfuric acid, good quality of refined sulfuric acid, and creation of values for enterprises.

Description

technical field [0001] The invention belongs to the field of chemical production equipment, in particular to a corrosion-resistant desorption tower. Background technique [0002] The desorption tower is an important equipment in the production of sulfuric acid. The traditional sulfuric acid desorption tower is made of steel and lined with acid-resistant tiles. During the production of refined sulfuric acid, due to the corrosion of acid-resistant tiles by sulfuric acid, there will be more impurities in the refined sulfuric acid product, and the quality will be lower. failed. Contents of the invention [0003] The object of the present invention is to provide a simple structure, corrosion-resistant desorption tower, which is especially suitable for use in the sulfuric acid industry. [0004] The technical solution of the present invention is: a corrosion-resistant desorption tower, the tower body is a cylinder body, the top of the tower is provided with an exhaust port, the...
