Filter filter is the filtrate at the outlet to form a negative pressure as the driving force of filtration. This filter is divided into two kinds of intermittent operation and continuous operation. The intermittently operated cartridge filter can filter suspensions at various concentrations, and the continuous cartridge filter is suitable for filtering thick, thick suspensions containing solid particles.
Intermittent operation of the filter can be achieved because of automation and development, increasing the size of the filter. In order to obtain a low moisture content of the filter residue, mechanical press filter has been developed. In this case,
The filter is used to separate the container into the upper and lower chambers, which constitute a simple filter. The suspension into the upper chamber, under pressure through the filter medium into the lower chamber as the filtrate, solid particles are trapped in the filter medium surface to form residue. In this case,
宁夏11选5走势图 During the filtration process, the filter layer on the surface of the filter medium gradually thickens, the resistance of the liquid through the filter layer increases, and the filtration rate decreases. When the filter chamber is full of filter cake or filter speed is too small, stop the filter, remove the filter residue, the filter media regeneration, to complete a filtration cycle. In this case,
Through the filter layer and filter media must overcome the resistance, so filter media on both sides of the filter must have a pressure difference, which is to achieve the driving force of filtration. Increase the pressure difference can accelerate the filtration, but the pressure deformation of the particles in the large pressure difference is easy to plug the filter media pore, bag filter but slow down.
