Ceramic filter plate cleaning agent and application thereof in cleaning of ceramic plate filter

Abstract

The invention discloses a ceramic filter plate cleaning agent and application thereof in cleaning of a ceramic plate filter. The cleaning agent is prepared from the following raw materials in parts by weight: 10 to 98 parts of water-soluble inorganic solid acidic salt, 10 to 98 parts of solid inorganic acid, 8 to 98 parts of water-soluble solid organic acid, 0.1 to 5 parts of a metal ion complexing agent and 0.1 to 5 parts of a surfactant. The ceramic filter plate cleaning agent provided by the invention can improve the configuration and use safety, has the characteristics of environmental protection, green and the like, and most importantly, can obtain the same cleaning effect as nitric acid. The cleaning agent disclosed by the invention is solid, good in safety and convenient to store and transport; the cleaning agent disclosed by the invention does not release heat in a preparation process, is high in dissolving speed and is colorless and odorless; the cleaning agent provided by the invention can obtain a cleaning effect similar to that of nitric acid. Cleaning water after use of the cleaning agent is low in acidity, small in corrosivity and low in chemical oxygen demand (COD), and the cleaning water meets the direct discharge standard.

Description

technical field [0001] The invention belongs to the field of cleaning in mining production, and in particular relates to a cleaning agent formula of a ceramic filter plate cleaning agent and the application of the cleaning agent in cleaning a ceramic plate filter. Background technique [0002] Ceramic filter is a high-efficiency and energy-saving filter equipment commonly used in mines, especially in flotation and magnetic separation processes that require filtration. The working principle of the ceramic filter is similar to that of the traditional vacuum filter. The biggest difference is that the ceramic filter does not use air-permeable and water-permeable filter cloth, but uses microporous ceramic sheets as the filter medium. Vacuum is maintained with little loss. The working area of ​​the ceramic filter is divided into slurry suction area, drying area, discharge area and backwashing area. When the ceramic filter starts to work, the filter plate is submerged in the slur...

AI Technical Summary

Problems solved by technology

According to the actual production, nitric acid has a large safety management hidden danger

98% nitric acid, commonly known as fuming nitric acid, is a hazardous chemical that fumes violently in the air, causing frequent burn accidents; acid mist corrodes equipment, pipelines, and workshops seriously; nitric acid has high storage requirements and requires special safety and environmental protection Facilities; the nitric acid dilution process is difficult to operate, heat releases quickly, and requires careful and slow operation

The precipitation of nitrogen dioxide gas is also harmful to the occupational health of personnel

Due to the strong corrosiveness of nitric acid, safety accidents frequently occur during the cleaning process. At the same time, the cleaning waste liquid pollutes the environment and causes corrosion to structures.
