1, material characteristics
In the production process of PPS, after the polycondensation reaction is completed, the solid phase is washed, the washing liquid is extracted and recovered, the solvent is evaporated, and the crystals are condensed to obtain the by-product inorganic salt sodium chloride.
Ingredients are complex, including sodium chloride, ash, low phenolic materials, solvents, etc.
High solid content, high viscosity, high temperature, 80-100 °C (usually 80,90 degrees Celsius)
After condensation, the material is agglomerated and has a high hardness.
Solid particle size distribution range is wide.
2, the current separation equipment overview and problems
At present, the siphon scraper centrifuge is used to separate the coarse-grained materials, and the separation liquid containing fine particles is separated by a LW horizontal decanter centrifuge.
Due to the large viscosity of the material, the material after condensation is agglomerated and has a high hardness, and the filter cloth is easy to be clogged, making it difficult to clean and regenerate. The siphon centrifuge can only be used as a settling centrifuge.
Failed to develop siphon blade centrifuge capabilities.
High energy consumption, large area, high maintenance costs.
Automatic discontinuous work, high labor costs.
The installation is complicated and the installation cost is high.
3, the advantages of GN solid-control centrifuge
According to the characteristics of the material, it is recommended to use a short drum spiral unloading settling mud centrifuge (dehydration centrifuge) + clarification decanter centrifuge to separate medium and coarse particles and fine particles.
There is no filter in both models, which can avoid the risk of filter clogging.
Low energy consumption, small footprint, low maintenance costs.
Automatic and continuous work, low labor costs.
The installation is simple and the installation cost is low.
GN Solid Control Decanter Centrifuge can continuously feed, dehydrate and unload the sodium chloride in the polyphenylene sulfide desalting section during full-speed operation. It has a sealed operation, large processing capacity, stable performance, low energy consumption, and separation efficiency. it is good. It overcomes the shortcomings of existing separation equipment such as intermittent operation and small production capacity, saves investment, and simplifies operation.
