Vacuum processes in fine chemical industry
Thread Content
Let’s all share what types of vacuum equipment (vacuum units, vacuum pumps) are used in our fine chemical industry Are there more water rings or more dry types? Power consumption, efficiency, and wastewater treatment, among other things!
In fact, it depends on the specific application. Water ring pumps are being phased out in many places due to the large amount of wastewater generated, but they remain convenient to use in some areas. Although oil-free pumps are cleaner, they require frequent maintenance and the replacement of air valves, which is troublesome. Another example is applications in distillation that require a high vacuum; nowadays, screw pumps are often used as a substitute for vacuum systems. There are quite a few effects. There are also various vacuum devices that are widely used, such as vacuum dryers. We use double cones quite often
Generally, vacuum pumps are used in complete evaporation units. If you’re interested, you can add me on WeChat at kk470878679 or on QQ at 3225774384 to discuss this further
What kind of vacuum pump is mainly used in vacuum dryers?
Vertical reciprocating vacuum pumps are used quite often, right?
Due to wastewater issues, the water ring type is hardly used these days; the choice of vacuum pump is mainly determined by considerations related to vacuum level. Reciprocating vacuum pumps are often used in combinations such as the W4 model; when paired with rotary vane vacuum pumps, they can achieve a high level of vacuum. Of course, using a vacuum pump system saves more space.
The problem with water ring systems is wastewater, while the advantage is a very low failure rate. The problem with screw compressors is their high failure rate; moreover, the medium remains unpolluted, but the maintenance costs are very high.
Now, claw-type dry pumps are being used more often – they save electricity, achieve high vacuum levels, and produce no wastewater.

This screw may not look great, but it hasn’t been photoshopped; what matters is its performance!
