Abstract

The invention discloses a gas-liquid mixing distribution system. The system comprises a shell, and a catalyst grid, a cold hydrogen distributor, a collecting disc, gas-liquid distributors and a distribution disc which are arranged in the shell from top to bottom; mixing chambers are uniformly arranged on the collecting disc; and the distribution disc is fixedly connected with distribution disc supporting beams and the inner wall of the shell, the gas-liquid distributors are vertically fixed to the distribution disc, and flow crushing plates are arranged on the distribution disc and located onthe two sides of the distribution disc supporting beams and at the lower end of the gas-liquid distributor located on the inner wall of the shell. Cold hydrogen can be more uniformly distributed on the total cross section of a reactor, dead zones on the inner wall of the shell and the distribution disc supporting beams are reduced, and the uniform distribution of gas and liquid on the total crosssection of the reactor is fully guaranteed.

Description

Technical field [0001] The invention belongs to the field of petroleum processing, and specifically relates to a gas-liquid mixing distribution system. Background technique [0002] Due to the exothermic reaction of gas, liquid and solid in the hydrogenation process, if the reaction feed (gas and liquid two phases) and the catalyst (solid phase) are in full, uniform and effective contact, the hydrogenation reactor is generally designed There are multiple catalyst beds, a distribution plate is set on the top of each bed, and a temperature control structure (cold hydrogen tank) is set between the two beds to ensure the safe and stable production and extension of the hydrogenation unit The service life of the catalyst. [0003] Hydrocarbon hydrogenation reaction is an exothermic reaction. For a multi-bed hydrogenation reactor, the temperature of oil and hydrogen will increase after the reaction of oil and gas in the upper bed. In order to continue the effective reaction in the next b...
