Numerical simulation and optimization of cleaning bidirectional nozzle of large petroleum storage tank

Abstract

In the process of storing petroleum for a long time, the coagulability substance in the petroleum will form high viscosity petroleum sludge at the bottom of the tank, resulting in the loss of petroleum, the decrease of reserves, and the internal corrosion. The main components of petroleum sludge are petroleum and wax, which have certain recycling value. In this paper, the numerical simulation technology is used to simulate and optimize the flow field of the bidirectional nozzle in the large petroleum tank cleaning device. The shape of the nozzle with fast velocity, steady jet-flow and high efficiency, solves the problem of deposit and cleaning of petroleum sludge in petroleum tank, and provides a new idea for the future design of the mechanical cleaning device for the petroleum tank.
