Vertical Pressure Leaf Filter
Product Details
Leaf filter element is generally constructed of 5 layers of metal woven mesh with different mesh counts by riveting. As the filter elements of the pressure leaf filter, generally 10 to 60 leaf filter elements are evenly placed. At the bottom, they are inserted into the mainifold that collects the filtrate. At the top, they are clamped by leaf clamping bar with spacer rings for easy installation and removal. Leaf filter elements can work with a variety of filtering aids and is suitable for decolorization filtration, pharmaceutical oil filtration, crystallization separation process, etc. in the production of oil and grease and chemicals.
Leaf filter elements are made of stainless steel (304, 316, 316L). We can choose the right leaf filter element to match up with your application according to your filtration environments.
Working Principle
Pressure leaf filters are divided into vertical pressure leaf filters and horizontal pressure leaf filters. Let's take the vertical pressure leaf filter as an example to explain how it works.
First, the liquid to be filtered flows in from the inlet at the bottom of the filter and moves upward under the action of pressure to make the liquid evenly distributed on every leaf filter element. Both sides of the filter element play the role of filtration. Impurities are trapped on the surface and clean liquid flows into the mainfold connected with the filter leaves through the central drainage layer and flows out from the outlet. When the impurities on the surface of the filter element reaches a certain thickness and the filtration efficiency slows down, compressed gas is blown into the filter housing. Dry the filter cake and shake it off to the butterfly valve at the bottom of the filter through the pneumatic vibration valve at the top of the filter and discharge the filter cake.
Structure
Every filter leaf consists of a drainage mesh, 2 layers of support mesh and 2 layers of fine filter mesh. Filter mesh adopts plain weave, plain Dutch weave, plain or twill reverse Dutch weave. Drain mesh and supporting mesh adopts plain weave, fine filter mesh adopts plain weave, plain Dutch weave, reverse plain Dutch weave or reverse Dutch twill weave.
