What causes moisture in soda ash production and how to deal with it?
Thread Content
During the production of soda ash calcination, a large amount of moisture is generated above the alkali silo, causing the alkali silo to scar, and the moisture also flows into the equipment, causing the screen mesh of the alkali screen to be clogged. What is the reason for the generation of moisture, what are the main components of moisture, and what is the most reasonable method to deal with it? In addition, is the amount of moisture generated in the pipeline large? Looking for help, heroes, thank you all again.
The alkali temperature is too low. If there is no way to improve the alkali discharge temperature, then add a dust removal device to the transportation equipment, either wet or dry method.
The main components of moisture are ammonia, carbon dioxide, alkali dust and air.
The alkali producing temperature should be at least above 150 degrees! ! 75 degrees is the alkali temperature of the calciner? It should be the alkali output temperature of the cold alkali machine.
The formation of moisture is mainly due to the condensation of moisture in the air, which is more obvious when the ambient humidity is high. Due to the occurrence of dew points, alkali dust that easily absorbs moisture and agglomerates immediately adheres to form scabs. The cool alkali temperature and the sealing degree of the alkali bin are factors that affect moisture. It is difficult to solve the moisture problem, but its harm can be reduced. In practice, it must be considered in combination with the process, and investment issues must also be considered.
The reason for the generation of moisture may be due to the low temperature of the alkali discharged from the calciner. Cooling alkali can be carried out through a cooling alkali furnace to reduce part of the moisture. Vat dyes can take over the air extraction on the transportation equipment.
