Embodiment 1

[0078] Example 1: Application of the supergravity device of the present invention in the enhanced decomposition of refractory organic matter

[0079] Hydroxyl radicals released when micro or nano bubbles burst can oxidize and decompose many organic pollutants. Compared with air micro-nano bubbles, ozone micro-nano bubbles remove the oxidation of hydroxyl radicals on the surface of the bubbles. Ozone itself has strong oxidative properties, which has a synergistic effect on the oxidative degradation of organic matter in wastewater, and enhances the treatment efficiency of organic matter.

[0080] The traditional aeration method generally uses the method of injecting macroscopic air bubbles into the water to increase oxygen in the water body. However, due to the rapid rise of the macroscopic air bubbles in the water, the gas-liquid mass transfer efficiency is low and the oxygenation effect is poor. In contrast, the rising speed of micro-nano bubbles in the water body is slow, and...

[0087] Embodiment 2: Application of the supergravity device of the present invention in glycerin oxidation reaction

[0088] The multiphase oxidation of glycerol to produce high value-added oxidation products is an important branch of the biodiesel industry chain. Glycerol can be converted into many high value-added chemical products through oxidation, such as dihydroxyacetone (DHA), hydroxypropionaldehyde, glyceraldehyde etc., and then processed into various products, showing new scientific significance and application value. Conventional production processes of these chemicals (such as potassium permanganate oxidation, nitric acid oxidation, and chromic acid oxidation) or low-yield fermentation processes have limited industrial applications and yields. The catalytic oxidation of glycerol is a complex process of multiple parallel reactions and series of reactions. Therefore, choosing an efficient reactor to effectively regulate the direction of catalytic oxidation of glycerol...

[0095] Embodiment 3: Application of the supergravity device of the present invention in liquid phase hydrogenation reaction

[0096] The traditional trickle bed hydrogenation technology adopts gas-liquid-solid three-phase, and the reaction only occurs on the surface of the catalyst wetted by the liquid phase, and the hydrogen must be dissolved in the liquid phase to react on the liquid-solid surface.

[0097] One of the requirements for liquid-phase hydrogenation is that the amount of hydrogen dissolved in the reactor feed should be higher than the amount of hydrogen required for the reaction. This can be achieved by adding hydrogen recirculation to the high-efficiency gas-liquid mixer, and the saturated liquid circulating material provides the reaction The required hydrogen can omit the circulating hydrogen compressor; because there is no need to dissolve hydrogen in the reactor, the gas-liquid mass transfer resistance in the entire reactor is eliminated; when designing the si...

Abstract

The invention discloses a hyper-gravity device for enhancing a reaction by gas-liquid efficient premixing and an application method thereof. The hyper-gravity device comprises a motor, a main shaft, arotor, a shell, a liquid distributor, a secondary shaft, a speed-increasing gear, a speed-increasing gear output shaft and a charging cavity, wherein the main shaft at an output end of the motor passes through the bottom of the shell and extends into the shell; the rotor is fixed on an upper part of the main shaft; the charging cavity is arranged on an upper part of the shell; a lower part of thecharging cavity is connected with the liquid distributor; the main shaft is fixedly connected with the speed-increasing gear through the secondary shaft; the output shaft of the speed-increasing gearpasses through the bottom of the charging cavity and extends into the charging cavity; stirring wings are arranged on a part of the output shaft of the speed-increasing gear in the charging cavity. By adopting the hyper-gravity device, gas is distributed in a liquid phase in a nano-micron size, long gas retention period and high gas-liquid mass transfer efficiency are achieved, and the macro-reaction rate is increased effectively.

Description

technical field [0001] The invention belongs to the field of supergravity devices, and in particular relates to a supergravity device and an application method for enhancing reaction through gas-liquid high-efficiency premixing. Background technique [0002] The supergravity device is a typical chemical strengthening equipment. In a hypergravity environment, the huge shear force tears the liquid into micron or even nanometer-sized liquid film, liquid filament and liquid droplet, resulting in a huge and rapidly renewed phase interface, making the mass transfer rate between phases faster than that of traditional tower reactions. The process of micro mixing and mass transfer is greatly enhanced. At the same time, since the flooding velocity of the counter-current rotating bed is about 40% higher than that of the packed tower, the gas velocity can be appropriately increased to increase the processing capacity. [0003] For some oxidation or hydrogenation reactions involving in...
