Description
Technical field
The utility model relates to a kind of filtering and purifyings, more particularly, to a kind of novel cross flow filter.
Background technique
In petrochemical industry and pharmaceutical industry, catalyst, active carbon or perlite etc. can be often used in process of production, it is raw
Producing need to separate it with product solution when completing, this can be separated by solid-liquid separation often using crossflow filtration technique.In cross-flow
During filter, the direction of feed liquid circulation and the direction of filtering are at an angle of 90 degrees, in this way filtering shearing of the material flow through generating when film surface
Power takes away the particle being detained on film surface, so that pollution layer be made not generate or maintain a relatively thin level.It is existing frequently-used
Cross-flow filtration system have ceramic membrane cross-flow filtration system, filter process are as follows: raw material and solid particle in reaction raw materials tank
After booster pump pressurizes, by being equipped with the filter of ceramic element, solid particle is intercepted by the micropore on ceramic membrane channel surface,
Clear liquid without solid particle passes through the outside that fenestra penetrates into membrane tube, and next procedure is entered after collecting；Consolidated by what micropore intercepted
Body particle, can in ceramic membrane channels swiftly flowing material wash away and take away, filter cake will not be formed on membrane tube surface, by pottery
The concentrate of porcelain candle filter (because of the extraction of clear liquid, solid content can increase than reaction raw materials, referred to as concentrate)
It is returned in head tank through piping, again passes by booster pump pressurization, filtering, circulation.
But ceramic membrane cross-flow filtration system also suffers from certain drawbacks, such as: 1, because cross-flow filtration needs to guarantee film surface
Flow velocity causes to transport in 2~5 meter per seconds so every suit ceramics membranous system requires to configure the circulating pump motor of a set of hundred kilowatts
Energy consumption is higher during row, for example the ceramic membrane of 100 square meters at least needs to configure the circulating pump motor of 110KW, in operational process
Energy consumption is surprising；2, single set ceramic membrane filter system processing capacity is small, if you need to expand processing capacity can only more set systems it is in parallel, investment
Greatly, utilization rate of equipment and installations is low, takes up a large area；3, filtering accuracy narrow range, it is conventional there was only 50/100/200 nanometer of three kinds of specification；4,
Existing ceramic membrane filter system, field pipes connection is complicated, and valve, the evaporating, emitting, dripping or leaking of liquid or gas phenomenon of instrument are more serious.
