A cleaning agent and its application in cleaning ceramic filter plates

Abstract

The invention discloses a cleaning agent and application thereof to cleaning of ceramic filter plates. The cleaning agent mainly comprises the following components: metal ion complexing agent, organicpenetrant, main agent A and main agent B, the main agent A is at least one of water-soluble organic acid, and the main agent B is soluble salt corresponding to the main agent A. The main agent B in the cleaning agent can promote the insoluble metal salt of the main agent A to be dissolved into aqueous solution, so that the cleaning effect is enhanced, the metal ion complexing agent and the organic penetrant can generate a synergistic effect, so that fine particle-sized metallic minerals blocking filter holes can be dissolved and insoluble attachments and organic chemicals can be cleaned off,consequently, a ceramic plate can be fully and thoroughly cleaned, the production efficiency of a ceramic filter is improved, the service life of the filter plate is prolonged, and the production costis reduced.

Description

technical field [0001] The invention relates to the technical field of cleaning, in particular to a cleaning agent and its application in cleaning ceramic filter plates. Background technique [0002] Ceramic filter is a kind of equipment that uses microporous ceramic plate as filter medium and applies the principle of capillary effect to realize solid-liquid separation. When the capillary force in the micropores of the ceramic plate is greater than the pressure difference between the two ends of the micropores, the micropores will remain filled with liquid, and air will not pass through the micropores. When the filter plate is immersed in the pulp, in the absence of external force, the dehydration process starts with the help of the natural force generated by the capillary effect, and the solid particles in the pulp accumulate on the surface of the filter plate to form a filter cake, thereby achieving the purpose of solid-liquid separation. [0003] In actual industrial pro...

Problems solved by technology

Ultrasonic cleaning is to "cavitate" the bubbles generated by high-frequency vibrations, "bombard" the attachments on the surface of the ceramic filter plate, and use mechanical methods to make them fall off, so as to realize the cleaning of the surface of the filter plate, but it is difficult to clean the ceramic plate. Blockage inside micropores; chemical cleaning method, mainly using nitric acid, hydrochloric acid, hydrofluoric acid, oxalic acid or a compound of the above acids, combined with some salts and surfactants to clean the ceramic filter plate , because this type of cleaning agent uses more inorganic acids, it is harmful to the human body and the environment, and is corrosive to the equipment. At the same time, the cleaning process needs to heat the acid solution, which is not environmentally friendly and low-carbon, and the cleaning effect is also limited. , cannot achieve the purpose of thorough cleaning
