Liquid filter PTF series

platepressurefor chemical applications

Pressure-tight plate type filter is an efficient, energy-saving, Closed-loop operation of the precision clarification filtration equipment, it is widely used in Petroleum and Petrochemical, Fine chemicals, Oil, Paint, Food, Pharmaceutical and Other industries. All the filter elements are made of stainless steel. As the whole filtration process is operated in a closed vessel, it can perfectly replace the traditional "plastic plate and frame filter press", and can also realize the heat preservation filtration. The device can be customized to manual slag and automatic slag two forms, is very convenient and to eliminate the defect of leak out material and pollution and so on. because of the "open" structure of traditional filter press, and the filtration accuracy is very high, the filter area is from 2 ㎡ to 80 ㎡ for the user to choose. According to the requirements of filtration process, Optional materials of sealed vessel is carbon steel and stainless steel. The filter body is composed of a shell, filter plate, cap, slag discharging device etc. the filter plate is made of multi-layer stainless steel filter screen, Installed on the center liquid collecting pipe, installation, disassembly, and cleaning is very convenient. In the process of Filtration, the filter liquor with filter aid flow into the filter through the transport system, and then, a stable filter cake is formed on the surface of filter screen. (filter cake has a numerous micro channels), until the filter liquor enter into the filter cake layer and pass it , the filtration process is finished. Filtering Principle ◆ Wire mesh + Filter adjuvant + Pressure
