Drainage and stirring device for concentrated sulfuric acid dilution treatment

Abstract

The invention relates to a drainage and stirring device for concentrated sulfuric acid dilution treatment. The device comprises a workbench, a containing device and a stirring device. The containing device is fixedly installed at the upper end of the workbench. The stirring device is mounted at the upper end of the containing device. The stirring device comprises a motor, a connecting rod, a stirring cylinder, a stirring frame, a positioning plate and a drainage frame. According to the drainage and stirring device, heat generated in a stirring process is utilized through the containing device,meanwhile, the stirring of the stirring device is prevented from being disturbed; the purpose of stirring concentrated sulfuric acid and water during drainage is achieved through the stirring device;meanwhile, the dissipation of heat generated by the mixing of the concentrated sulfuric acid and the water is accelerated, so that water boiling caused by too high heat can be prevented; the drainageframe and the stirring cylinder move in the same way through the positioning plate; and the flow of the concentrated sulfuric acid is limited in the drainage process of the concentrated sulfuric acid, so that the situation that the stirring quality is affected due to the too large introduction amount of the concentrated sulfuric acid can be prevented.

Description

technical field [0001] The invention relates to the field of concentrated sulfuric acid processing, in particular to a concentrated sulfuric acid dilution treatment drainage stirring device. Background technique [0002] Since dilute sulfuric acid is often used in the production of chemical fertilizers, it is also widely used in chemical industry, medicine, plastics, dyestuffs, petroleum refining and other industries, so the demand for dilute sulfuric acid in industrial production is very large, and industrial production of dilute sulfuric acid is generally through It is obtained by diluting concentrated sulfuric acid. Since concentrated sulfuric acid is easy to generate a lot of heat when it is mixed with water, it needs to be continuously stirred and cooled when diluting concentrated sulfuric acid. [0003] In the process of diluting concentrated sulfuric acid, due to the chemical properties of concentrated sulfuric acid, there are the following problems in the actual oper...

AI Technical Summary

Problems solved by technology

[0004] (1) In the traditional concentrated sulfuric acid dilution treatment drainage stirring device, in the process of drainage and stirring of concentrated sulfuric acid, the general drainage parts can only be used for drainage, and in order to prevent interference with the mixing process, the drainage parts need to be separated from the equipment to reduce the processing efficiency

[0005] (2) In the process of draining and stirring the concentrated sulfuric acid in the traditional concentrated sulfuric acid dilution treatment drainage and stirring device, the heat generated during the dilution process is generally directly discharged out of the equipment, which is easy to cause waste of heat resources
