Abstract
The invention relates to the field of refined acid production, in particular to a refined acid production method and production system. A method for producing refined acid in a refined acid productionsystem includes the following steps: S1, placing the pyrite on the upper side of the orifice plate, and heating the pyrite at high temperature by the electric heating plate to generate sulfur dioxide and ferricoxide; S2, Drive the orifice plate and the pyrite on it to rotate, so that the pyrite is heated evenly; S3, crush the pyrite on the upper side of the orifice plate when the crushing ring moves up and down, so as to fully release sulfur dioxide; S4, calcining cylinder The sulfur dioxide and oxygen generated inside enter the contact chamber from the outlet pipe through the hose and the inlet pipe, and vanadiumpentoxide is placed in multiple catalyst cartridges. The sulfur dioxide and oxygen are in contact with the vanadiumpentoxide, and the electric heating ring heats the contact chamber at the same time. Sulfurtrioxide is generated; S5. The sulfur trioxide generated in the contact chamber enters the absorption cylinder from the connecting pipe, and puts concentrated sulfuric acid on multiple trays.
Description
technical field [0001] The invention relates to the field of refined acid production, in particular to a refined acid production method and production system. Background technique [0002] The application number is a refined sulfuric acid production system disclosed in CN201210430546.1. This invention discloses a refined sulfuric acid production system. The method solves the problems in the prior art that the production process requires the participation of personnel and the labor intensity of personnel is high. The present invention selects the SO3 gas transformed in the production of industrial sulfuric acid, purifies and separates it through the filter device, and then the pure gas enters the absorption device for absorption with desalinated water, and the unabsorbed gas is returned to the sulfuric acid production system through the dehumidification device through the pipeline for dehumidification. For reuse, the absorbed sulfuric acid flows into the absorption device thr...
