Gas-liquid distributor for solid particle or polymer system

Technical Field

The invention relates to the technical field of gas-liquid distributors, in particular to a novel gas-liquid distributor for a system with solid particles or polymers.

Background

As tower technology has evolved, improvements and developments in tower internals technology have continued to be made in optimizing tower operating performance. The packed tower is used as important mass transfer equipment in the industrial production fields of oil refining, petroleum, chemical industry and the like, and the optimization of the liquid distributor can greatly improve the operation performance of the tower and the mass transfer efficiency of the packing.

At present, among a plurality of gas-liquid distributors, the distributor with a better liquid distribution effect is a slotted disc type gas-liquid distributor, and the slotted disc type gas-liquid distributor is a device which is formed by welding a plurality of rectangular gas risers with liquid guide and distribution holes on a bottom plate. Therefore, the trough-tray type gas-liquid distributor is generally used for liquid phase redistribution in the middle of the packed tower, not only can the liquid be uniformly distributed, but also the requirement of side line liquid extraction can be met.

The device has the obvious defects when solid particles or polymer systems exist, firstly, the solid particles or the polymer can block the distribution holes, and the phenomena of liquid channeling, wall flow, blockage and the like of the groove disc type gas-liquid distributor are easily caused, so that the separation efficiency of the filler is influenced, and the service life of the device is shortened; secondly, solid particles or polymers can flow into the filler and adhere to the surface of the filler to cause blockage, thereby influencing the separation efficiency of the filler.

In order to achieve the purpose, the invention provides the following technical scheme: a novel gas-liquid distributor for solid particle or polymer system comprises a bottom groove plate, an air lifting groove plate is arranged on the bottom groove plate, the bottom of the gas lifting groove plate is hermetically connected with the bottom groove plate, the upper end of the gas lifting groove plate is provided with evenly arranged overflow holes, the interior of the gas lifting groove plate is of a pipeline structure, the interior of the gas lifting groove plate is connected with the upper end of a liquid guide plate, the lower end of the liquid guide plate penetrates through the bottom groove plate, the liquid guide plates below the bottom groove plate are bent downwards along the direction of 45 degrees and then are bent downwards vertically, and the bottom of the vertical downward section is cut into uniform V-shaped teeth, the bottom groove plate, the gas lifting groove plate and the liquid guide plate jointly form a groove plate, every two groove plate plates are connected through a bolt, thereby forming a gas lifting channel, the top of the gas lifting channel is connected with a liquid blocking cap, and the plurality of grooved disc plates are lapped on the distributor support ring and are fixed by clips.

Preferably, the bottom groove plate is formed by welding a bottom plate and L-shaped connecting plates on two sides.

Preferably, the overflow holes are V-shaped overflow holes.

Preferably, the liquid blocking cap is bolted to the top of the lift channel.

Preferably, the bending directions of the pair of liquid guide plates at the bottom of the fluted disc plate corresponding to each air lifting channel are opposite.

The invention has the technical effects and advantages that: the invention not only avoids the problem that the distribution holes are blocked by solid particles or polymers, but also effectively avoids the problem that the separation efficiency and the treatment capacity of the filler are reduced after the particles flow into the filler.

Detailed Description

In the description of the present invention, it should be noted that unless otherwise specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly and may be, for example, fixedly connected, detachably connected, integrally connected, mechanically connected, or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements.

Example 1

As shown in fig. 1-3, a novel gas-liquid distributor for solid particle or polymer system comprises a bottom trough plate 1, wherein a gas-lifting trough plate 2 is installed on the bottom trough plate 1, the bottom of the gas-lifting trough plate 2 is hermetically connected with the bottom trough plate 1, overflow holes 3 are uniformly arranged at the upper end of the gas-lifting trough plate 2, a pipeline structure is arranged inside the gas-lifting trough plate 2, the gas-lifting trough plate 2 is internally connected with the upper end of a liquid guide plate 4, the lower end of the liquid guide plate 4 passes through the bottom trough plate 1, the liquid guide plate 4 below the bottom trough plate 1 is bent downwards along 45 degrees and then bent downwards vertically, and is cut into uniform V-shaped teeth 5 at the bottom of the vertical section, the bottom trough plate 1, the gas-lifting trough plate 2 and the liquid guide plate 4 jointly form a trough plate 6, every two trough plates 6 are connected by bolts to form a gas-lifting channel 7, the top of the gas-lifting channel 7 is connected with a liquid-blocking cap 8, the plurality of tray panels 6 are lapped over the distributor support ring 9 and secured by clips.
