polyester Desulfurization belt/ Vacuum filter belt
Mainly used for: series rubber belt type vacuum filter, horizontal vacuum belt filter, vacuum drum filter, vertical filter press, etc.
Apply to power plant wet desulphurization, tailings, metallurgy, mining, chemical industry, coal chemical industry, papermaking, food, pharmaceutical and environmental solid-liquid separation industry.
Vacuum belt filters also known as horizontal belt filters are usually a lot bigger compared to a belt filter press and these installations work based on the principles of gravity instead of pressing. Vacuum belt filters are different when it comes to the treatment of sludge and the output pertaining to belt filter press.
Vacuum belt filters can process high volumes of sludge which means reduced operating costs compared to other filtration alternatives. However this installation is not only used to separate solids from liquids, but foremost to obtain a output of cake with a high purity level. This installation washes the sludge at different stages on the wire mesh belt/filter cloth belt in order to obtain this pure cake. This cake has a low moisture level at the output of the vacuum belt filter and without the small polluting particles due to the washing. However, the purity and moisture level at the end of the vacuum belt filter is higher compared to the belt filter press. Another benefit is the low energy consumption level of the vacuum belt filter in terms of economies of scale but also in terms of absolute energy consumption.
So the belt filter press as well as the vacuum filter belt make use of the same synthetic wire mesh in order to filter sludge. Drenth Holland bv is very experienced in the production of filter cloth within these installations, feel free to contact us if you have a question concerning these type of filter belts.
this is usually a very large and wide installation for processing high volumes. These type of belt filters are used within the water treatment industry, sewage treatment industry, food industry, mining industry, mineral industry, paper industry, pharmaceutical- and chemical industry. Those polyester wire mesh belts are built to withstand severe conditions like humidity and tension.
