High-temperature hot filtration equipment for sodium chloride
Thread Content
Material to be filtered: 1. Filtration at high temperature of 95 degrees； 2. Weakly alkaline medium: PH=7.2~8 ； 3. Filter out solids: sodium chloride ； 4. The concentration of the suspension can be adjusted according to the requirements of the filtration equipment; I would appreciate advice from experts to help me select the appropriate filtration equipment.
It is better to use a centrifuge, as it results in a lower moisture content, which can range from 4% to 6%. However, given the high temperature and the presence of chloride ions, it is important to choose appropriate materials for the parts of the centrifuge that come into contact with the material – materials like 2205 are suitable for this purpose; otherwise, the equipment may be damaged. Generally, centrifuge manufacturers require a high salt concentration in the feed material, but too high a concentration can easily cause blockages in the pipelines. It is advisable to achieve a salt concentration of 20%-25% for salt extraction, and a swirl chamber should be installed above the centrifuge’s feed inlet to increase the salt concentration.
Which is better: a two-stage pusher centrifuge or a vacuum filter (disk-type or drum-type)? Is it necessary to add insulation material to the filtration equipment or to use a jacketed design with steam heating?
Choose the type with a pusher and a drum; it has a high processing capacity, and no insulation is required on the outside of the equipment, but insulation is needed for the feed pipelines.
It does not provide insulation, and there is concern that salts may precipitate in the filtrate. Okay, thank you~
