Production technology and processing equipment of energy-saving and environment-friendly liquid sodium hydroxide

Abstract

An energy-saving and environment-friendly liquid sodium bicarbonate production process, the specific steps are as follows: A. charging, B. melting, C. detection, D. discharging, E. cooling, F. purification; a liquid sodium bicarbonate processing equipment, It includes a boiler, a liquid sodium sodium processing device is fixed on one side of the boiler, and a high-temperature liquid sodium sodium cooling output device is fixed on one side of the liquid sodium sodium processing device. The present invention utilizes the installation of a liquid sodium natron processing device and a high-temperature liquid sodium sodium cooling output device on the side of the boiler, so that a large amount of solid sodium sodium can be melted, and high-temperature and high-pressure liquid sodium silicate can be cooled and output. Compared with the traditional dissolution kettle and static autoclave, the liquid sodium sodium processing equipment has the advantages of fast dissolution of solid sodium hydroxide, energy saving, no scarring in the dissolution container, and for the dissolution of high modulus solid sodium carbonate, Due to the use of steam for dissolution, high silicic acid polymers are rarely produced, and the dissolved liquid sodium bicarbonate has a uniform concentration.

Description

technical field [0001] The invention relates to the field of chemical processing, in particular to an energy-saving and environment-friendly production process and processing equipment for liquid natron, which is used for processing solid natron into liquid natron. Background technique [0002] Sodium silicate, also known as sodium silicate, water glass, its molecular formula is: Na 2 O n SiO 2 or Na 2 O n SiO 2 · m H 2 O: The abatine produced in the abatine processing plant is all solid abatrine, one is for the convenience of storage and safety, and the other is for the convenience of transportation, but in many cases, it is necessary to process the solid abatrine into a liquid There are two kinds of common equipment for processing solid sodium sodium into liquid sodium sodium in the market: dissolving kettle and static autoclave. Among them, the dissolution kettle, when the modulus is less than 3, the efficiency is low. High (sodium naphthalene is made of Na 2 O and ...

[0003] Chinese invention patent CN 101508441 B discloses a direct dissolution process of molten sodium silicate. The direct dissolution process of molten sodium silicate is to directly flow the liquid pure sodium silicate in the molten state into the dissolution roller, and the The water undergoes hydration reaction, and the molten pure sodium silicate at high temperature is used to directly heat the water and use high temperature water to dissolve the liquid pure sodium silicate. This dissolution method is suitable for bubble flowers with higher modulus Alkali is not easy to dissolve. Due to the high silicon content of high film number foam alkali, its hydrolysis rate is greater than the dissolution rate, and the hydrolysis produces high silicic acid polymers (ie silica gel) to form precipitates and adhere to its surface. High silicic acid polymers are A viscous white large block, the effect of water quenching is not obvious, and when the amount is too large, it will block the hole on the elbow, resulting in poor discharge
