Dongguan Punock Vacuum Technology Co., Ltd. analyzed the customized vacuum solutions for alumina industry, and what application of rotary vane vacuum pump in alumina plant?
Alumina, chemical formula Al2O3. It is a high hardness compound with a melting point of 2054 C and a boiling point of 2980 C. Ionic crystals can be ionized at high temperatures. It is often used to make refractories.
Rotary vane vacuum pump is one of the most basic vacuum acquisition equipment in vacuum technology. Rotary vane vacuum pumps are mostly small and medium-sized pumps. There are two kinds of rotary vane vacuum pumps: single stage and double stage. The so-called two-stage structure is to connect two single-stage pumps in series.
Generally, it is made into two stages to obtain higher vacuum.
When choosing rotary vane vacuum pump in alumina plant, the following points should be paid attention to when considering suction pressure:
1. Because the slurry is suspended when the carbonation decomposition rate of the filter is too high and pastes the filter cloth like jelly, it is difficult to filter, and the vacuum degree increases rapidly.
2. The size of Al-H particles in the slurry from the carbon groove of the sintering alumina production system is uneven, especially some ultrafine Al-H particles, which can easily clog the filter cloth, and the sintering Al-H slurry can make the filter cloth harden easily, and the vacuum degree will increase rapidly.
3. Because of the loss along the way and other reasons, the suction pressure at the filter is always lower than that at the inlet of the rotary vane vacuum pump.
