Equipment for transfer of energy at an still functioning under pressure towards a still functioning under vacuum, comprises an exchanger that constitutes single heating mode of the vacuum, two deflectors, and a vacuum control device

摘要

The simplified equipment comprises an exchanger (F1) that constitutes single heating mode of the still functioning under vacuum (A1V) by feeding heating fluid by hydro-alcoholic steam emitted by still functioning under pressure (A1P) or by steam of boiler, two deflectors placed laterally to a tubular bundle, and a device for controlling the vacuum by calibrated valve that is placed upstream of the vacuum pump. The tubular bundle is fed with hydro-alcoholic steam emitted by A1P, or with steam of boiler by a network of pipes and valves defining the bypass. The simplified equipment comprises an exchanger (F1) that constitutes single heating mode of the still functioning under vacuum (A1V) by feeding heating fluid by hydro-alcoholic steam emitted by still functioning under pressure (A1P) or by steam of boiler, two deflectors placed laterally to a tubular bundle, and a device for controlling the vacuum by calibrated valve that is placed upstream of the vacuum pump. The tubular bundle is fed with hydro-alcoholic steam emitted by A1P, or with steam of boiler by a network of pipes and valves defining the bypass. A pump (Pc) ensures the extraction and the return of condensates towards still A1P or to the boiler by networks of pipes. The deflectors are placed on two sides of the tubular bundle and are positioned along the bundle to create a chimney. The tubular bundle is divided into several units operating at the same time. The control of vacuum is provided by depression safety valves. The calibrated pressure of each valve is expressed in bar absolute, and decreases with increasing the diameter of the valve when more valves are installed. An independent claim is included for a process for transfer of energy at a still functioning under pressure towards a still functioning under vacuum.
