Hydrostatic tank inertisation apparatus

摘要

Commercially available inertisation apparatuses as well as the 2-chamber dry-respiration appliance and inert-gas supply with pressure reducers possess sealing surfaces. These bond together or become leaky in time and therefore incapable of functioning. In order to prevent sealing surfaces from bonding together or becoming leaky, a hydrostatic apparatus has been developed. This consists of: The liquid tank (B1), the blow-off conduit (L8) and the conduit system (L1), (L2), (L3), (L4), (L5), (L6) connected at the bottom, the pressure reducer (D1) and the feed conduit (L7). In the pressureless state, the tank (B1) and the riser (L2) have the same height (H1). In the working state, the liquid level in the riser (L2) is pushed to the value (H2) by the pressure reducer (D1). In the event of a pressure rise, for example as a result of the filling of the storage tank, the liquid level drops to (H3). The waste gas subsequently escapes through the tank (B1) and the waste-gas conduit (L8). The apparatus is suitable for protective-gas overlays in chemical storage tanks, reactors, etc. In general, for protection against oxygen and moisture in storage tanks. <IMAGE>
