Fractal bubble configuration controllable type slurry bed reactor

Abstract

The invention relates to a fractal bubble configuration controllable type slurry bed reactor, and belongs to a gas-liquid reactor device. The bubble controllable strong mixing is conducted at different reactor heights. According to a strong mixing internal part, a plurality of A-type strong mixing components are evenly distributed on a supporting partition plate of the reactor, and an M-type distribution component is arranged on the upper side of each A-type strong mixing component. Each A-type strong mixing component comprises a liquid phase lifting pipe, a gas phase lifting pipe, a short connection transverse pipe and a tail end nozzle, wherein liquid in the liquid phase lifting pipe is mixed with gas from the gas phase lifting pipe and the short connection transverse pipe, the mixture enters the tail end nozzle to release nitrogen bubbles of multiple dimensions, and the local liquid phase jet flow is formed above the partition plate. According to the slurry bed reactor, small bubbles are generated in throat pipes of the liquid phase lifting pipes through liquid phase entrainment, large bubbles are formed in the tail end nozzles through curved surface nozzle shearing, the gas-liquid flowing is even, the gas-liquid level below the partition plate is stable, the bubbles formed above the partition plate are controllable in dimensional, the liquid phase turbulence is strong, and the heat removal and mass transfer of the slurry bed reactor are facilitated.

Description

Technical field [0001] The invention relates to bubble reactor equipment, especially for the fields of hydrocracking and hydrorefining of inferior residual oil. The bubble size is adjustable under fluctuating conditions of high temperature and high pressure reactors, and a fractal bubble configuration that meets actual industrial applications Controllable slurry bed reactor. Background technique [0002] Slurry bed reactors are widely used in three-phase reactions such as coal-to-liquid Fischer-Tropsch synthesis reactions and residual oil hydrogenation. These reactions exotherm strongly and require heat to be taken inside the reactor. In addition, the diameter of the slurry-bed reactor can be up to 5 meters. In the process of reactor amplification, uneven temperature distribution often occurs, resulting in excessive local temperature rise, carbon deposition or deactivation of the catalyst, and decreased reaction selectivity. Consequences affect the amplification effect. Therefor...
