How to choose the filter medium and filter aid of the water park wave equipment ? Today, Guangzhou Blue Wave put forward a detailed answer to this doubt raised by everyone. First of all, we all know that filtration is one of the important steps in purification. The choice of filter media will directly affect the clarity of the filtered grease and the smoothness of the unloading. Therefore, pay special attention to the selection of filter media and filter aids. Then let's take a look at it together.
In fact, the filter media used in the grease industry is mostly a woven medium. Commonly used 20 yarns of 5-8 strands of canvas, twill and plain white cloth and other cotton fabrics. Also used are 130#, 240#, 260#, 261# polyester filter cloth and 828# dimension nylon filter cloth and other chemical fiber products. The number of warp and weft strands is used for crude oil filtration, and the number of strands is small for essential oil filtration. For some high filtration requirements, a layer of white cloth or flannel is required outside the coarse filter cloth. In addition, a stainless steel wire woven filter screen is often used, a 30-40 hole/cm filter screen is used for the oil filtration, and a 140-180 hole/cm filter screen is used for the decolorization oil filtration.
Then, for the suspension containing more colloidal particles, the addition of the filter aid can effectively increase the filtration speed. Especially for some water park equipment subject to process restrictions, the suspension system for increasing temperature filtration cannot be used, and the application of filter aids is of great significance. If leaching oil is used to prepare edible phospholipids, diatomaceous earth should be added as a filter aid; in dewaxing, it must be filtered at a lower temperature, and the effect of the filter aid is more obvious.
