Definition and introduction of ceramic filters

The ceramic filter is composed of a porous body with two end faces and a peripheral face separated from the next to form a plurality of main flow paths of the purified fluid from one end face to the other end face and a filter membrane arranged on the inner surface of the main flow path. Through a transverse lateral opening into the mainstream way, be purged of fluid through porous membranes and plastid inside to purification, and as a cleaning fluid was removed from the outer surface of porous plasmids, or through the outer surface of porous plastid inflow, purified of fluid through porous plastid inside for purification and filtration membrane, And is removed as a purifying fluid from at least one end face side opening of the main flow path.

Ceramic filter is a kind of filter widely used, it uses rigid microporous material as filter element. It includes ceramic, corundum, silicon carbide, sand chip and a series of filters. Because OF too LARGE AIRFLOW CAN MAKE dust adhere to the filter, causing blockage, in order to prevent too large airflow directly blowing ceramic cup, so in the outside of the ceramic cup plus a protective cover, so that the airflow around the lower part of the filter, and then into the filter. In order to reduce the invalid volume, the bottom of the filter is tapered and a splitter is added. On the one hand, it blows the dust away; On the other hand, due to the constant flow of gas, the gas exchange is accelerated and the lag time is reduced. A ceramic filter system is designed to facilitate the replacement and cleaning of the filter. When a filter is blocked, two four-way directional valves can be turned to pass the sample gas into another filter, and the blocked filter can be blown back through high-pressure air, so that the dust attached to the ceramic filter cup is removed. The two filters work in rotation. It is suitable for more important analytical systems as well as sampling systems with high dust content which are prone to blockage.
