Diseño y construcción de un tanque didáctico con agitador de doble camisa y serpentín para el laboratorio de transferencia de calor de la facultad de ingeniería mecánica : tanque de doble camisa.

Abstract

Steam is used in the industry as a raw material and as a heat exchange medium for a lot of industrial processes. It is for this reason that the study of steam system is essential to know its operation and energy saving opportunities. In the present project, the design and construction of a double jacket agitator tank was carried out, which will be used as didactic equipment in the Heat Transfer Laboratory at the National Polytechnic School. The design of the tank was made according to the availability of the steam; the tank will be connected to a boiler with a capacity of 3 BHP (50 kg/h of saturated steam) at a pressure of 4 bar. Once the operating conditions were defined, a volumetric dimensioning of the tank was made by means of the heat transfer analysis between the inside of the double jacket where the steam circulates and the inside of the tank where a fixed volume of water is contained, once the volumetric capacity of the tank was defined, the extreme dimensions were calculated as well as the thickness of the walls and the lower head according to the ASME BPVC Code Section VII-Division 1, once the calculations were finished, a 3D model of all the components that constitute the tank was elaborated as well as their respective assembly and workshop drawings, finally the construction of the tank was carried out according to the obtained dimensions, also the different components and standard accessories that the tank requires for its operation were selected.
