Abstract

The invention discloses a microbubble generator for a reinforced hydrogenation technology. The microbubble generator mainly comprises a main pipe, a Venturi tube, an air inlet pipe and an ultrasonic generator. The Venturi tube and the main pipe are coaxially arranged and are welded to the inner wall of the main pipe. A detached annular air-inlet space is formed between the outer wall of the Venturi tube and the inner wall of the main pipe. The air inlet pipe is welded to the outer wall of the main pipe and is communicated with the annular air-inlet space. The Venturi tube is prepared from a microporous material. The air inlet pipe, the annular air-inlet space and micropores of the Venturi tube form gas channels. The inner wall of the Venturi tube and the inner wall of the main pipe form a gas-liquid channel. The ultrasonic generator is installed on the outer wall of the main pipe and is located in the downstream of the Venturi tube. The microbubble generator can improve hydrogenation efficiency and realize deep and high efficiency hydrotreatment or hydrocracking of an oil product.

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 ...
