Abstract An Air Dehumidifier can be designed and modeled working on simple principle of dehumidification of compressed air by means of collision with the number of cylinders arranged in series. This dehumidifier will not require any hygroscopic media or absorptive media such as Activated Alumina, Silica gel, Salt tablets, etc. which are used in other dehumidifiers. It does not require any refrigerant which is used in the refrigerated dehumidifier. The designed dehumidifier will be most reliable for the point of application. The dehumidifier will be designed to operate at a high pressure of 250 P.S.I. This can be designed as per the theory of thin cylinder. From the design calculations the stresses of the proposed dimensions were within the…show more content…
Patrick at Johns Hopkins University, he patented the desiccant kind of material. The material came into existence in 1640’s which was used as the absorptive medium for poisonous gases during the World War-I. This material is generally Silica gel. The desiccant dehumidifier was invented and patented by Hanns F. Arledter, Edward R. Stacy and Clayton E. Bruke in United States on 8th Nov. 1963. While the dehumidifier having deliquescent material was patented by Philip S. Becker in19th April 1996 in United States. This dehumidifier uses hygroscopic media filled in vessel. The material uses salt which have affinity to the moisture. The most common salts are ferric ammonium citrate, potassium hydroxide, etc. The membrane dehumidifier was invented and patented by Ravi Prasad in Praxair Technology Inc. in the year 1993 on 27th April. A two stage membrane dehumidifier employs two stages. The first stage is to remove the water vapor from the air and second stage is to complete the process of…show more content…
