Embodiment 1

[0017] A kind of preparation technology of natron, comprises the following steps:

[0018] A. Raw material preparation: mix quartz sand and soda ash at a weight ratio of 2.5:1;

[0019] B. Melting: Add the quartz sand and soda ash mixed in step A into a kiln at a temperature of 1440°C for melting. After melting for 1.5 minutes, add diatomite with 4% of the mass of soda ash and zeolite powder with 0.1% of the mass of soda ash. After stirring evenly, continue the melting time for 2.5 minutes to obtain the reaction material; C, cooling: cool the reaction material obtained in step B on a chain plate machine with a cooling water device, and cool the reaction material to 280 ° C;

[0020] D. Dissolving: Put the reaction material cooled to 280°C in step C into the dissolution furnace, then add water according to the ratio of reaction material to water weight ratio of 2.5:1, and then boost the steam pressure of the dissolution furnace to 0.8MPa, Dissolved into a liquid reaction mater...

Embodiment 2

[0026] A kind of preparation technology of natron, comprises the following steps:

[0027] A. Raw material preparation: mix quartz sand and soda ash at a weight ratio of 2.8:1;
