AI Technical Summary

Technical Problem

Traditional sodium silicate production suffers from problems such as discontinuous production, significant waste of thermal energy, and poor reaction uniformity, leading to unstable product quality.

Method used

The sodium silicate reactor with gradient thermal field design forms a temperature gradient field through the coordinated arrangement of steam chamber, cyclone mass transfer device and multi-stage reaction chamber. The cyclone mass transfer device generates swirling flow to improve mass transfer rate and heat transfer efficiency. Combined with stirring device and discharge overflow pipe, continuous flow of materials is achieved.

Benefits of technology

This achieves efficient utilization of thermal energy, ensures uniformity and stability of reaction temperature, improves production efficiency and product purity, reduces energy consumption, and guarantees the continuity and stability of the production process.

Abstract

The invention relates to the technical field of sodium silicate production, in particular to a sodium silicate reaction kettle with a gradient thermal field, which comprises a kettle body, an upper partition plate, a middle partition plate and a lower partition plate are sequentially arranged in an inner cavity of the kettle body from top to bottom, and the inner cavity is divided into a first-stage reaction chamber, a steam chamber, a slurry chamber and a second-stage reaction chamber by the upper partition plate, the middle partition plate and the lower partition plate; a material inlet and an exhaust pressure valve are arranged at the top of the primary reaction chamber, and a steam inlet is formed in the steam chamber; the slurry overflow pipe vertically penetrates through the upper partition plate and the middle partition plate and is used for guiding slurry in the first-stage reaction chamber to the slurry chamber; through cooperative arrangement of the steam chamber, the rotational flow mass transfer device, the multi-stage reaction chamber and the exhaust pipeline, high-temperature steam sequentially flows through all stages of reaction areas, and a temperature gradient field with the temperature of the steam chamber, the temperature of the second-stage reaction chamber and the temperature of the slurry chamber and the temperature of the first-stage reaction chamber is formed. Therefore, heat energy is accurately distributed according to the reaction process, local overheating or insufficient reaction is avoided, comprehensive energy consumption is greatly reduced, and efficient gradient utilization of the heat energy is achieved.
