Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a kaolin processing method for preparing coking inhibitor components, which solves the problem that the existing kaolin prepared inhibitors have low reaction efficiency, which leads to poor inhibitory effect, It is necessary to add a large dose of inhibitor every time the boiler is cleaned to ensure that coking can be well suppressed in the boiler. It is impossible to improve the reaction efficiency of kaolin by improving the ingredients of kaolin, and it is impossible to improve the reaction efficiency of kaolin by mixing hydrogen into kaolin. Alumina changes its acidity and alkalinity to improve the reaction efficiency of kaolin, which greatly reduces the effectiveness of boiler coking inhibitors

Abstract

The invention discloses a kaolin processing method for preparing coking inhibitor components. The invention specifically includes the following steps: S1, dispersion, S2, sand removal, S3, classified magnetic separation treatment, S4, flotation and ultrafine grinding Processing, S5, calcining processing, S6, post-processing of kaolin, the present invention relates to the technical field of chemical material production. The kaolin processing method used to prepare the coking inhibitor component can improve the reaction efficiency of kaolin by improving the ingredients of kaolin, and achieve a good effect of changing the acidity of kaolin by adding aluminum hydroxide to kaolin. Alkalinity, to improve the reaction efficiency of kaolin, greatly enhances the effectiveness of the boiler coking inhibitor. It is not necessary to add a large dose of inhibitor every time the boiler is cleaned to ensure that the coking can be well suppressed in the boiler, which greatly facilitates people's use. The coking inhibitor performs coking treatment inside the boiler.

Description

technical field [0001] The invention relates to the technical field of chemical material production, in particular to a kaolin processing method for preparing coking inhibitor components. Background technique [0002] Kaolin is a kind of clay and clay rock mainly composed of kaolinite clay minerals. It is a kind of non-metallic mineral. The mineral components of kaolin are mainly kaolinite, halloysite, hydromica, illite, montmorillonite and quartz, Composed of minerals such as feldspar, pure kaolin is white and delicate, soft and soft, and has good physical and chemical properties such as plasticity and fire resistance. Kaolin is widely used, mainly for papermaking, ceramics and refractory materials, and secondly for coatings, rubber Fillers, enamel glazes and white cement raw materials, used in small quantities in plastics, paints, pigments, grinding wheels, pencils, daily cosmetics, soaps, pesticides, medicines, textiles, petroleum, chemicals, building materials, national ...
