Description
Technical field
The utility model belongs to continuous production processes, in particular to a kind of continuously to neutralize device and utilize the continuous neutralization
The technique that device is continuously neutralized.
Background technique
The essence of neutralization reaction is: H+And OH-In conjunction with generation water (H2) and salt O.Acid+alkali → salt+water has salt and water to generate
Reaction, is not necessarily neutralization reaction such as: 2NaOH+CO2=Na2CO3+H2O, no matter so which kind of degree proceeded to, as long as soda acid
Reaction has occurred and just cries neutralization reaction.Judge whether complete neutralization whether is reacted completely as standard just using soda acid.
Neutralization reaction belongs to exothermic reaction mostly, and process must remove heat as early as possible, to guarantee the stabilization of reaction temperature, work
Industry production is usually to carry out in batch reactor, and require height to operating technology, and material must be carefully slowly added to, otherwise
There is phenomena such as overheat, bumping, general tower, not only influences product quality and yield, it is also possible to accident can be caused, causing can not be pre-
The consequence estimated.And operating process is more complicated, is usually associated with the process of heating and cooling, and energy will not obtain abundant benefit
With causing the waste of resource.After the completion of the characteristics of interval neutralization reaction is an only upper procedure, next road work just can enter
Sequence, can not continuous production, not only waste the time, reduce production efficiency, and need equipment number is more, personnel labor intensity
Greatly, complicated for operation, it is unable to satisfy the needs of large-scale production.
In chemical production process, the operation or chemical engineering unit operation of reactor either during chemical unit, by it
Mode of operation can be divided into interval, continuous and semi-batch operation.
Intermittently operated, which refers to, puts into a batch materials into equipment at the beginning of operation every time, after some processing, excludes all
Product, then feed intake again.Feature is fluctuation of service.Intermittently operated production process is fairly simple, and investment cost is low；Production process
Middle map function process conditions, driving, parking are generally easier；Production chains are bigger, and the operation of product is easier,
Suitable for the reaction being technically difficult to realize using continuous operation.Such as suspension polymerisation, due to reactant physical property or
Reaction condition is industrially difficult to adopt continuous operation process, uneconomical realizing continuous operation process.There is solid
In the presence of, the serialization of chemical engineering unit operation is relatively difficult, such as crush, filtering, drying occupied with batch process procedures
It is more.The characteristics of according to batch process procedures, generally to fine chemicals such as the medicine of small mount, multi items, dyestuff, adhesives
Production, synthesis and compound process use this mode of operation relatively broadly.Some chemical products are in pilot stage, due to right
The understanding and method of controlling operation thereof of technological parameter and product quality rule are not mature enough, and are also usually sought using intermittent process
Look for suitable process conditions.Large-scale production process is using the less of intermittently operated.
Production system has material constantly to exchange with the external world during continuous operation, and material continuously flows into system,
And system is left continuously with product form, the material quantity into system is equal with the product volume taken out from system, if
Standby middle each point material properties will not time to time change.Therefore continuous process is mostly steady state operation.Production process is carried out continuously, if
Standby utilization rate is high, and production capacity is big, automatic operation easy to accomplish, and technological parameter is stablized, and product quality is preferably guaranteed.
But the investment of consecutive production process is big, requires the technical level of operator relatively high.Continuous operation process is suitable for skill
The large-scale industrial production of art maturation.The large production equipment of the chemical products of whole realization industrialized production is essentially all
It is produced using continuous operation method.
