The development prospects of vacuum filters take you to understand

Vacuum filter is a kind of equipment
that uses vacuum negative pressure as the driving force to achieve solid-liquid separation.
Under the action of vacuum negative pressure (0.
04-0.
07MPa), the liquid in the suspension is extracted through the filter medium (filter cloth), while the solid particles are trapped by the medium, so as to realize the separation
of liquid and solid.
Its structural filtration section is arranged along the horizontal length, which can continuously complete filtration, washing, drying, filter cloth and other operations
.
Rubber belt filter has the advantages of
high filtration efficiency, large production capacity, good washing effect, low cake moisture, flexible operation and low maintenance cost.
Rubber belt filter can be widely used in metallurgy, mining, chemical industry, papermaking, food, pharmaceutical, and other fields of solid-liquid separation, especially in the flue gas desulfurization gypsum dehydration (FGD) has a good application
.
Vacuum belt filter press is a new type of filtration equipment with a high degree of automation, and its products are widely used in: thermoelectric, chemical, papermaking, building materials, smelting, rubber, food and other fields
.
The new filtration equipment that is developing in the future includes: mechanical press filtration equipment; Dynamic filter that can realize filter residue layer filtration; Washing large-scale filtration equipment
for coal sewage treatment, chemical industry and petroleum industry.
In the theoretical research of filtration, the measurement of filtration resistance and porosity of the filter residue layer, the filtration speed, the simulation and amplification of the filtration equipment, the clarification and dynamic filtration mechanism of thin liquid, and the research of the filter medium are all important topics
.
The use of electronic computers to control filtration operations is the development direction
of filtration equipment.
