Industrial tests show that under the normal use condition, the average service life of the composite steady-flow false bottom reaches 5.5 years, is far longer than that of the conventional metal steady-flow false bottom, even exceeds that of the polyurethane steady-flow false bottom, and is lower in cost than that of the polyurethane. Meanwhile, due to the adoption of the standardized design, the comprehensive performance of the composite flow-stabilizing false bottom is ensured, the interchangeability with the installation size of the original single-material flow-stabilizing false bottom is kept, and the universality and the standardization level are improved. The composite steady-flow false bottom with the same specification and the original steady-flow false bottom made of the single material have good interchangeability, so that the equipment is convenient and fast to transform and upgrade.
