Sintered mesh candle filter is generally made of 5-layer 304 or 316L stainless steel woven mesh after special laminating or vacuum sintering. This filter not only has excellent corrosion and high temperature resistance, but also offers high mechanical strength and overall rigidity after laminating and sintering. The mesh opening is not easy to deform and delivers stable filter rating and easy cleaning property during filtration.
The excellent corrosion resistance of the sintered mesh candle filter not only helps to filter out corrosive solids or liquid impurities, but also protects the process equipment and the inner surface of pipeline, thus improving the chemical industrial process and reducing the frequency of regular maintenance operations.
We can offer sintered mesh candle filters made of Hastelloy, Monel and other alloys to meet the various requirements of customers.
The filtrate enters at the bottom of the filter and moves upward, which helps to keep the solids in suspension so that they are evenly deposited on the surface of the filter elements. Impurities are retained on the surface of filter elements, and clean filtrate is discharged from the filter through the register. When the filter reaches the set pressure value, the control system stops feeding and the residue liquid in the filter is drained out. The backblowing begins. When the backblowing is finished, the dry cake is discharged from residue discharge nozzle. Close the residue discharge nozzle when the dry cake discharging is finished. The surface of the filter elements is clean and ready for the next round of filtration.
A standard and the most widely used sintered mesh. It is a combination of 5 layers of wire mesh with different openings and mesh counts after laminating and vacuum sintering. Standard 5-layer sintered mesh has higher strength than stainless steel fiber felt, and better air permeability than sintered porous products. We can also offer 6-layer sintered mesh that adds another layer of square weave mesh on the 5-layer sintered mesh to offer higher mechanical strength and compression strength.
It is fabricated by sintering multiple layers of square weave mesh (or Dutch weave mesh) and stainless steel perforated metal (round or square pattern) together. As a result, it combines the good permeability of woven mesh and the excellent mechanical strength of perforated mesh. In addition, it features great backwashing effect and low pressure lose
It is constructed of two or three layers of plain Dutch weave wire mesh after laminating and sintering. It features uniform opening distribution and stable permeability.
It is made of multiple layers of square plain weave wire mesh after sintering. Square weave wire mesh has square hole opening and high open area rate, so this sintered mesh has excellent permeability, low resistance, high flow rate, etc.
Compared with polymer melt filtration, chemical filtration requires low temperature and low pressure. So, sintered mesh candle filter has a diversity of connection types. Connection types are customized upon request.
