Abstract

The invention discloses a microbubble generator for intensifying hydrogenation process, which is mainly composed of a main pipe, a Venturi pipe, an intake pipe and an ultrasonic generator; the Venturi pipe and the main pipe are coaxially arranged and welded on the inner wall of the main pipe, An independent annular air intake space is formed between the outer wall of the Venturi tube and the inner wall of the main body tube. The air intake tube is welded on the outer wall of the main body tube and communicates with the annular air intake space. The Venturi tube is made of microporous materials. The air inlet pipe, the annular air inlet space and the micropores of the Venturi tube together form a gas channel, and the inner wall of the Venturi tube and the inner wall of the main tube together form a gas-liquid channel; the ultrasonic generator is installed on the outer wall of the main tube and is located in the venturi tube downstream. By adopting the invention, the hydrogenation efficiency can be improved, and deep and efficient hydrogenation treatment or hydrocracking of oil products can be realized.

Description

technical field [0001] The invention relates to a bubble generator, in particular to a microbubble generator for strengthening hydrogenation process. Background technique [0002] Hydrotreating and cracking of various oil products is the most reasonable and effective method to maximize the utilization of crude oil and upgrade oil products. The existing oil hydrogenation technology is divided into fixed bed hydrogenation, moving bed hydrogenation, suspension bed hydrogenation and ebullated bed hydrogenation, etc. Various oil hydrogenation processes have different bed types, and the hydrodynamic properties of the gas-liquid flow are quite different, but the chemical reaction between the oil and hydrogen occurs under the action of the catalyst. As long as the hydrogen dissolves more before the raw oil enters the reactor, supersaturated dissolution can be achieved, the hydrogen-oil ratio in the operation of the device can be reduced, and the reaction efficiency can be improved ...
