Embodiment Construction
[0037] The present invention will be further described below in conjunction with the accompanying drawings.
[0038] Such as figure 1As shown, the gas-liquid mixing and distributing device of the present invention includes a housing 1, a catalyst grid 2 fixed on the inner wall of the housing 1 and a catalyst grid support beam 3, fixed on the inner wall of the housing 1 and positioned on the catalyst grid 2 The collecting tray 4 below, the cold hydrogen distributor 12 fixed below the collecting tray 4 through the cold hydrogen distributor support beam 5, the bubble cap 6 located under the cold hydrogen distributor 12 and fixed on the rough distribution plate 7, and the rough distribution The gas-liquid distributor 11 below the plate 7 and fixed on the distribution plate 10. The distribution plate 10 is fixedly connected to the distribution plate support beam 8 and the inner wall of the housing 1 respectively, and the distribution plate 10 is located on both sides of the distri...

The invention discloses a gas-liquid mixing and distributing device. The device comprises a shell, and a catalyst grid, a collecting disc, a cold hydrogen distributor, gas-liquid distributors and a distribution disc which are arranged in the shell from top to bottom; and the collecting disc is fixedly connected with the cold hydrogen distributor, 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, gas-liquid spray heads on the two sides of the distributiondisc supporting beams are oppositely arranged in a staggered mode or obliquely arranged in pairs, and the gas-liquid spray heads on the inner wall of the shell are arranged right opposite to the innerwall of the shell or obliquely opposite to 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 cross section of the reactor is fully guaranteed.
Description
technical field [0001] The invention belongs to the field of petroleum processing, and in particular relates to a gas-liquid mixing and distributing device. Background technique [0002] Due to the exothermic reaction of gas, liquid and solid in the hydrogenation process, in order to make the reaction feed (gas and liquid two phases) and the catalyst (solid phase) fully, uniformly and effectively 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 box) is installed between the two beds to ensure the safe and stable production and extension of the hydrogenation unit Catalyst service life. [0003] The hydrogenation reaction of hydrocarbons is an exothermic reaction. For a multi-bed hydrogenation reactor, the temperature of oil gas and hydrogen will rise after the reaction of the upper bed layer. In order to continue the effective react...
