Embodiment 1 and comparative example 1

[0016] For the gas-liquid system, atmospheric pressure air is used as the gas medium, and the liquid phase medium is water. Experimental reactors were bubbling bed reactor (Comparative Example 1) and bubbling heterogeneous reactor (Example 1). Among them, the inner diameter of the outer cylinder of the bubbling bed reactor is 0.30m, the total height of the reactor is 3.0m, and the bottom of the reactor is spherical and equipped with a gas distributor. The internal diameter of the bubbling heterogeneous reactor (column body 1) is 0.30 m, the total height of the reactor is 3.0 m, the bottom 7 of the reactor tower is spherical, and a gas distributor 3 is installed near the bottom of the tower. The bubbling multiphase reactor is equipped with six trays 2 with a distance of 0.3m between the trays. On the trays, 50 gas risers 4 are arranged upwards. The gas risers are arranged in an equilateral triangle. The height of the gas risers is 10mm and the inner diameter is 8mm. Two air ho...

Embodiment 2

[0020] For the gas-liquid-solid three-phase system, the atmospheric pressure air is used as the gas medium, and the coal-water slurry with a concentration of 20% is the liquid-solid phase. The particle size of coal is less than 0.15mm, and the reactor used in the experiment is a bubbling multiphase reactor. The inner diameter of the tower body 1 of the bubbling multiphase reactor is 0.30m, the total height of the reactor is 3.0m, and the bottom 7 of the reactor tower is spherical. A gas distributor 3 is installed near the bottom of the tower. The reactor is equipped with six trays 2 with a spacing of 3.0m. On the trays, 50 air risers 4 are arranged upwards. The long air pipes are arranged in concentric circles. The height of the air risers is 10mm and the inner diameter is 8mm. Four ventilation holes 8 with a diameter of 1.5 mm are regularly opened, and two downcomers 5 are arranged symmetrically downward on both sides of the tray.

Abstract

A bubbling-type multi-phase reactor for the gas-liquid or gas-liquid-solid reaction with high reaction efficiency and mass transfer efficiency and excellent hydromechanical performance is composed of a tower body, 2-8000 tower trays with 10-200 gas-rising tubes and 1-5 down-flow spouts on each tower tray, and gas distributor.

Description

technical field [0001] The invention relates to the field of chemical engineering equipment, in particular to a bubbling heterogeneous reactor. technical background [0002] Gas-liquid or gas-liquid-solid three-phase reactors are widely used in the fields of chemical industry, energy, environment and biochemistry. Bubble or mechanical stirred tank reactors are usually used for gas-liquid or gas-liquid-solid reactions. These two types of traditional reactors have low efficiency and high energy consumption, and their application fields are limited by the reaction system. In a multiphase flow reactor, mass transfer, mixing and heat transfer between phases are important technical indicators that determine the performance of the reactor, and directly affect the reaction intensity, conversion rate and product quality. For gas-liquid or gas-liquid-solid reaction systems, the mass transfer between phases is often the key factor determining the effect of the reactor. Especially fo...
