Abstract

The invention provides a fluid uniform distribution device with a fractal structure. The fluid uniform distribution device is arranged in a multi-phase reactor, and at least comprises a distribution plate and a fractal member, wherein the distribution plate is arranged at the bottom of the multi-phase reactor, and the fractal member penetrates through the distribution plate to be arranged in the multi-phase reactor. The fluid uniform distribution device can reduce the pressure drop of the distribution plate, further can reduce the energy consumption, also can enable fluid which enters the reactor to be distributed more evenly and improves a fluidization effect; in addition, the standing time for the fluid in the reactor is adjustable, and the fluid uniform distribution device is strong in operation flexibility.

Description

technical field

[0001] The invention relates to the field of reactor internals, in particular to a fluid uniform distribution device with a fractal structure used in multiphase reaction systems such as fluidized beds and slurry beds. Background technique

[0002] Fluidized bed reactors have unique advantages, such as efficient mass and heat transfer, uniform temperature field, large particle processing capacity, and wide gas-solid operating range, etc., which have been widely used in many industrial fields . However, with the development of various industrial fields and the enlargement of equipment scale in recent years, the diameter of the reactor has been increasing, making the uniform distribution of gas in the fluidized bed a key issue in the design of industrial fluidized bed reactors.

[0003] The fractal structure was proposed by Mandelport, the father of fractals. The gas uniform distribution device made of fractal structure, due to the similarity of the flow channe...
