Dead end filtration system

[Abstract]:
Liquid/solid separation is very common in unit operations of chemical engineering, and we will choose different filtration solution to solve the problem based on material’s temperature, flow

Liquid/solid separation is very common in unit operations of chemical engineering, and we will choose different filtration solution to solve the problem based on material’s temperature, flow, solid content, PH value, viscosity and related parameter. Shinkai provides dead end filtration system for batch production and cross flow filtration system for continuous production so as to solve customer’s various filtration, separation problem during production.

Applications

● Precious metal catalyst filtration in hydrogenation reaction

● Silicon tetrachloride filtration in polysilicon production

● Activated carbon filtration

● Lithium fluoride filtration

● Food and drink filtration

●Catalyst filtration in hydrogen peroxide and caprolactam production

 

Dead end filtration system

This kind of filter can be used for various concentration solid fluid filtration from outside to inside, easy operation, convenient maintenance, reliable and durable filtration capability with below mentioned advantages:

● Dismounting and assembling filter cartridge conveniently.

● Filter cartridge can be dismantled integrally.

● Space among filter elements is short, structure is compact, cost is lower.

● Good back flushing performance.

● Filter surface can reach 200m2, element can be borne 0.8MPa pressure drop, and filter cake can be 20mm.

● Suitable for precious metal catalyst filtration from mother solution in fine chemical production.

 

The dead end is filtered by an introvert system.

  

This kind of filter use inside-out filtering method, which can discharge solid from element inside through back flushing after each filtration cycle. Main advantage as below:

● Eliminate the problem of filter cake accumulation.

● Reduce residue liquid quantity in filter bottom.

● More filtration area.

● Good back flushing performance.

● Back flushing frequency is less and prolonged filter using time.

● Suitable for precious metal catalyst recovery, activated carbon, organic salt catalyst and slurry oil filtration.
