Problems solved by technology

[0005] The present invention can solve the problem that the existing equipment has poor filtering effect and incomplete filtering when filtering the gas generated after pyrite roasting, and cannot effectively completely remove the impurities inside the gas, and the impurities are easy to block the filter mesh holes. It affects the gas filtration effect. At the same time, when the existing equipment filters the gas generated after pyrite roasting, it cannot effectively collect the filtered impurities, and the collected impurities are inconvenient to clean, which affects the use effect of the equipment. and other difficult problems

Abstract

The invention relates to a pretreatment process for producing industrial concentrated sulfuric acid, which comprises a bottom plate, a shell frame, an air intake pipe and a filtering device. An air intake pipe is installed at the lower end of the left side, and a filtering device is installed inside the housing frame. The present invention can solve the problem that the existing equipment has poor filtering effect and incomplete filtering when filtering the gas generated after pyrite roasting, and cannot effectively completely remove the impurities inside the gas, and the impurities are easy to block the filter mesh holes. It affects the gas filtration effect. At the same time, when the existing equipment filters the gas generated after pyrite roasting, it cannot effectively collect the filtered impurities, and the collected impurities are inconvenient to clean, which affects the use effect of the equipment. Wait for the problem.

Description

Technical field [0001] The present invention relates to the field of industrial processing takes concentrated sulfuric acid, concentrated sulfuric acid and more particularly to an industrial pretreatment preparation. Background technique [0002] Sulfuric acid is an important basic chemical raw materials, the chemical industry is the most important products, primarily for the manufacture of inorganic fertilizers, followed by a basic chemical raw materials used in non-ferrous metal smelting, petroleum refining and petrochemical, textile, industrial salts, a these inorganic and organic acids, rubber industry, paint industry and defense industry, agricultural chemicals or pharmaceutical, leather, coking and other industrial sectors, but also for iron and steel pickling. [0003] Currently, the process made before the existing industrial sulfuric acid is taken, in general the following shortcomings: 1, a conventional gas generating device when after Pyrite was filtered, poor filtrati...
