Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] figure 1 It is a structural schematic diagram of the present invention. In the figure, the tubular gas-liquid distributor of the present invention includes an overflow weir 1, an overflow weir support 2, a central pipe 3, a slit 4, a distribution plate 5, a broken flow plate support 6, a broken flow plate 7 and an annular Step 8. The overflow weir 1 is a long strip rectangular tank, arranged in parallel with each other at intervals, such as Figure 4 shown. Weir supports 2 such as figure 2 As shown, the broken flow plate support 6 is as image 3 shown.

[0021] The central tube 3 is cylindrical, and its wall thickness can be 2-6mm, such as 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm or 6mm.

[0022] The central pipe 3 can be configured to include a first pipe section and a second pipe section connected to each other, the first pipe section is located ...

Abstract

The invention discloses a tubular gas-liquid distributor. The tubular gas-liquid distributor comprises a distribution disc, a central pipe and an overflow weir, wherein the lower end of the central pipe penetrates through a mounting hole in the distribution disc and is fixed to the distribution disc; the overflow weir is fixed and blocked above an opening in the upper end of the central pipe through overflow weir supporting pieces; space between the overflow weir supporting pieces below the overflow weir is used as a gas phase inlet; a slot parallel to the axis of the central pipe is formed in the pipe wall of the central pipe above the distribution disc and is used as a liquid phase inlet; and the overflow weir is a long-strip-shaped rectangular groove body, is fixedly connected with the plurality of central pipes and is shared by the plurality of central pipes. The tubular gas-liquid distributor has high operation flexibility, gas and liquid are mixed more evenly, the strength of the distribution disc where the tubular gas-liquid distributor is located is improved through the long-strip-shaped overflow weir, and the distribution disc can be prevented from deforming in a high-temperature use environment in a reactor.

Description

technical field [0001] The invention relates to the field of petrochemical industry, in particular to a tube-type gas-liquid distributor. Background technique [0002] Against the background of increasingly stringent environmental protection regulations, the standards for impurity content in various petroleum products are also increasing. As an essential technology in the process of clean fuel production, hydrogenation technology plays an important role in refinery production. Hydrogenation technology includes hydrocracking, hydrofining, etc. The hydrogenation reaction is an exothermic reaction. At present, most of the domestic reactors adopt a downflow fixed-bed reactor structure. The reaction materials flow through the catalyst bed from top to bottom, and undergo hydrogenation reaction under its action. During the reaction process, the uneven distribution of gas-liquid in the bed will cause hot spots in the reactor, catalyst coking, overheating, etc., which will affect ...
