| 摘要 |
The present invention refers to a breather bag (1) for atmospheric storage tank (2) vent seal that consists of a bag made with an impermeable and flexible membrane, to be used in storage and/or transportation of liquid product (7) in atmospheric tank (2), by working as a breather to air vent either in closed type or open type tank. Because the stored liquid product (7) in atmospheric storage tank (2) is kept physically separated from atmospheric air (8) by using breather bag (1), the following advantages are proportioned: it avoids evaporation losses of liquid products stored in atmospheric tanks (2). So, it avoids environment pollution by product gases that would be expelled out of the tanks. It avoids flame entry due to fire in atmospheric storage tanks that contain flammable or combustible liquids, so that it reduces occasional accident event. It avoids stored liquid product (7) from hydrocontamination by water presence in atmospheric air (8) in atmospheric storage tanks (2). It avoids stored liquid product (7) from contact with atmospheric air (8) oxidizing compound in atmospheric storage tank (2). It avoids extraneous objects entry into liquid products (7) stored in atmospheric storage tanks (2) like insects and small animals or birds, which may infect the stored liquid products (7). |
