Dilution treatment method for concentrated sulfuric acid industrial application

Abstract

The invention relates to a dilution treatment method for concentrated sulfuric acid industrial application. Equipment comprises a workbench, a motor, a stirring device and a conveying device, whereina motor is fixedly installed at the upper end of the workbench through a motor base; a stirring device is mounted on an output shaft at the upper end of the motor through a coupler; a conveying deviceis mounted at the right end of the stirring device; the stirring device comprises a liquid tank, an upper end cover, an inverted L-shaped frame, a heat transfer pipe, a double-acting cylinder and a stirring column. The motor is matched with the stirring device; the centrifugal force and the stirring device are used for uniformly stirring diluent, heat generated in the diluting process is recycledthrough the heat transfer pipe and the double-acting air cylinder, and the speed of concentrated sulfuric acid entering water is controlled through the conveying device so as to prevent the concentrated sulfuric acid from splashing due to a too high flow speed and from corroding equipment, so that the service life of equipment is shortened.

Description

technical field [0001] The invention relates to the technical field of preparation and treatment of concentrated sulfuric acid, in particular to a dilution treatment method for industrial application of concentrated sulfuric acid. Background technique [0002] Concentrated sulfuric acid is a strong mineral acid with high corrosiveness. It has strong water absorption, corrosion and oxidation properties. It can be used as a dehydrating agent and sulfonating agent. When it is mixed with water, it will release a lot of heat energy. It is also An important industrial raw material, it can be used to manufacture fertilizers, medicines, explosives, pigments, detergents and batteries, etc. It is also widely used in industries such as purification of petroleum, metal smelting and dyes, and is often used as a chemical reagent. [0003] In the process of diluting concentrated sulfuric acid, due to the chemical properties of concentrated sulfuric acid, there are the following problems in...

AI Technical Summary

Problems solved by technology

[0004] (1) When the traditional concentrated sulfuric acid industrial application dilution treatment equipment dilutes the concentrated sulfuric acid, a large amount of heat released by the concentrated sulfuric acid is often released to the outside air, resulting in a waste of energy

[0005] (2) When the traditional concentrated sulfuric acid industrial application dilution treatment equipment dilutes the concentrated sulfuric acid, it often increases the cooling time due to insufficient stirring, reduces the processing efficiency, and affects the quality of the diluted sulfuric acid
