High Strength Distillation Column Tower Equipment , It is widely used in chemical industry, petrochemical industry, metallurgy, light industry, textile industry, textile industry, chemical industry, metallurgy industry, textile industry, chemical industry, textile industry and so on. , Alkali, pharmaceutical, pesticide, electroplating, electronics and other fields. The main function of the distillation Tower is to separate the mixed liquid, the use of different liquids under different conditions, such as different temperature, volatile (boiling point) different principles of liquid separation, so as to achieve the purification effect. In addition to the aldehyde tower works is the mature mash of alcohol after crude distillation, from the gaseous form from the top of the crude distillation tower in addition to aldehydes, in addition to aldehyde tower and then the appropriate amount of heating, condensation, reflux, so that crude alcohol contained Of aldehydes, esters and other low boiling point, volatile impurities from the exclusion of the aldehyde tube from the aldehyde alcohol from the bottom of the tower into the liquid phase distillation tower, part of the head from the head of wine into the fermenter after the mash or mature Mash. The working principle of the distillation tower is not limited to the purification of alcohol. Distillation tower is mainly divided into plate tower and membrane tower.
HOW Pressure vessels works?
Pressure vessels can theoretically be almost any shape, but shapes made of sections of spheres, cylinders, and cones are usually employed. A common design is a cylinder with end caps called heads. Head shapes are frequently either hemispherical or dished (torispherical). More complicated shapes have historically been much harder to analyze for safe operation and are usually far more difficult to construct.
Theoretically, a spherical pressure vessel has approximately twice the strength of a cylindrical pressure vessel with the same wall thickness. However, a spherical shape is difficult to manufacture, and therefore more expensive, so most pressure vessels are cylindrical with 2:1 semi-elliptical heads or end caps on each end. Smaller pressure vessels are assembled from a pipe and two covers. For cylindrical vessels with a diameter up to 600 mm, it is possible to use seamless pipe for the shell, thus avoiding many inspection and testing issues. A disadvantage of these vessels is that greater breadths are more expensive, so that for example the most economic shape of a 1,000 litres (35 cu ft), 250 bars(3,600 psi) pressure vessel might be a breadth of 914.4 millimetres (36 in) and a width of 1,701.8 millimetres (67 in) including the 2:1 semi-elliptical domed end caps.
