The bag filter is a professional liquid filtration device in the process of use, and can effectively remove particles of different sizes in the liquid during use, so that the purpose of liquid filtration, purification, separation, and recovery can be achieved. .
The bag filter is mainly composed of three parts during the process of manufacturing. The filter bag, the filter container and the support basket are used. When the bag filter is used to filter the liquid, the liquid will be from the side of the filter container or Enter the liquid inlet below.
The bag filter will be filled in the filter bag above the filter bag supported by the basket. During the use process, the filter bag will be deployed due to the impact in the liquid and the uniform pressure surface, which will make the liquid material throughout The inner surface of the filter bag is evenly distributed. The liquid that passes through the filter bag is along the wall of the metal support basket and is discharged from the liquid outlet at the bottom of the filter.
When the bag filter is in use, its filtered particulate impurities are trapped in the filter bag, and the filtering process can be completed when in use, in order to maintain the high efficiency of the filter and the filtration accuracy and ensure that the downstream liquid is not contaminated, after running for a period of time. Should stop, open the filter cover, remove the retentate and filter bag together, replace the new filter bag, the replacement cycle depends on the actual situation.
Bag filter can use a kind of porous medium to separate the suspension during operation. During the working process, under the action of external force, the liquid in the suspension will flow through the pores of the medium, so that the solid particles will Will be retained, which will achieve a certain degree of separation, generally the suspension to be filtered is called filter; the porous media used is called filter media; the liquid passing through the media channels is called filtrate; solids are retained It is called filter cake or filter residue.
