Petrochemical Filtration Devices
In petrochemical industry and fine chemical industry, chemical reactor will be used for catalytic reaction, and a large number of noble metal catalysts will be used in the process of catalytic reaction, which requires filtration and separation. The reactor can be divided into batch reactor and continuous reactor. Both reactors need a large number of noble metal catalysts. In the actual production process, catalyst leakage often occurs, resulting in increased cost and environmental pollution. Therefore, efficient filtration method is needed to separate catalyst filtration.
According to the different parameters such as temperature, flow rate, solid content, Ph value and viscosity, different filter devices are selected.
With the heavy quality of FCC feed-stock, the yield of catalytic oil slurry becomes larger and larger, because the slurry contains a certain amount of solid impurities (mainly composed of catalyst particles and colloid and asphaltene attached to the catalyst). More solid matter not only increases the erosion of pipelines and equipment, but also has the danger of blockage furnace drunken, which seriously affects the quality of feed-stock oil. Therefore, if the solid matter in the slurry can be filtered out, the quality of the slurry will be improved, and the application will become more extensive, thus increasing the added value of the slurry product. Slurry filter is a kind of solid-liquid separation equipment which can filter the solid matter above microns in the slurry.

2BE1 series water ring vacuum pumps and compressors are the products with high efficiency and economical power, which are manufactured by our company integrating with the advanced technology of the imported products from Germany.
These series products adopt single stage and single action structure and have many advantages, such as, compact structure, convenient maintenance, reliable running, high efficiency and economical power.
Comparing with the SK, 2SK, SZ series water ring vacuum pumps used widely in our country at present, the 2BE series products are the ideal replacements of them for high vacuum, low power, and running reliability.
All the bearings are the imported products with the brand name of NSK orNTN for ensuring the precise orientation and the high stability during the working of the pump.
The material of the impeller is QT400 nodular iron or stainless steel for ensuring the stability when the pump works under the rigorous condition and can extend the lifetime of the pump.
The casing is made of steel or stainless steel plates to extend the lifetime of the 2BE1 series pumps.
The shaft bushing is made of stainless steel to improve the lifetime of the pump 5 times than the normal material.
The V-belt pulley(when the pump is drived by the belt) is used the high precise pulley with taper bushing to keep the reliability of the pump and extend its life. And it is also easy to mantle and dismantle.
The coupling is used to drive the pump directly. The flexible part connecting the two half coupling is made of polyurethane that makes the pump more reliable.
The unique design to set the separator above the pump saves the space and decreases the noise efficiently.
All the parts are cast by the resin sands that make the pumps' surface very smooth. It is not necessary to cover the surface of the pumps with putty and gives out the heat efficiently.
The mechanical seals (optional) are used the imported products to avoid the leakage when the pump works for a long time.
