Embodiment 1

[0028] The gas cooling tower of a certain gas purification device is a packed tower with a glass fiber reinforced plastic shell, and the inner diameter of the tower at the packing layer is 5 meters. The gas entering the tower is water-saturated wet gas, and the actual flow rate of the gas exiting the tower is 120km 3 / h, use 1150m 3 / h of acidic water to cool the gas, cooling the gas temperature from 76°C to 38°C. The spray density of the liquid is 51(m 3 / h) / m 2 .

[0029] A multi-disc liquid distributor is installed on the surface of the packing to distribute the acidic water, including the main liquid inlet pipe, the liquid inlet branch pipe, the liquid distribution pipe, the flow-restricting orifice plate, the liquid separation dish, and the liquid discharge pipe. The liquid drop pipe is inserted into the liquid distribution plate, the liquid separation plate is hung on the liquid distribution pipe, the flow limiting orifice plate is installed in the liquid distributio...

Embodiment 2

[0033] The sulfur trioxide absorption tower of a sulfuric acid plant is a packed tower with carbon steel lining bricks. The inner diameter behind the lining bricks at the packing layer is 6.8 meters, the height of the main packing is 2.5 meters, and there is a 0.2-meter-high defoaming layer above the main packing layer. filler. Sulfur trioxide in the gas is absorbed by sulfuric acid with a concentration of 98.3%. The acid volume in the upper tower is 660m3 / h, and the spray density is 25(m3 / h) / m2.

[0034]Install a multi-disc liquid distributor on the surface of the packing to distribute sulfuric acid, including the liquid inlet main pipe (namely the acid inlet pipe), the liquid inlet branch pipe (namely the acid inlet branch pipe), the liquid distribution pipe (namely the acid distribution pipe), the restricting orifice plate, Separating plate (namely acid plate), downpipe (ie acid drop pipe). The acid drop pipe is inserted into the acid distribution plate, the acid distribut...

Embodiment 3

[0037] The first absorption tower after the moisture absorption tower of the semi-dry acid production plant is a packing tower with carbon steel lining bricks. The inner diameter behind the lining bricks at the packing layer is 5 meters, the height of the main packing is 2.3 meters, and there is still 0.2 meters high above the main packing layer Defoaming layer packing. Sulfuric acid with a concentration of 98.5% is used to absorb sulfur trioxide, water and sulfuric acid vapor remaining in the gas. The acid volume in the upper tower is 80m3 / h, and the spray density is 4(m3 / h) / m2.

[0038] Install a multi-disk liquid distributor on the packing surface to distribute sulfuric acid, including the acid inlet main pipe, acid inlet branch pipe, acid distribution pipe, flow-restricting orifice plate, acid distribution disc, and acid drop pipe. The acid drop pipe is inserted into the acid distribution plate, the acid distribution plate is hung on the acid distribution pipe, the flow li...

Abstract

The invention discloses a multi-disc liquid distributor, which is used for distributing liquid in a packed tower. The multi-disc liquid distributor consists of a main liquid inlet pipe, liquid inlet branch pipes, liquid distribution pipes, flow limiting porous plates, liquid distribution discs and liquid falling pipes, wherein the liquid falling pipes are inserted into the liquid distribution discs; the liquid distribution discs are hung on the liquid distribution pipes; the flow limiting porous plates are arranged in the liquid distribution pipes; the liquid distribution pipes are connected with the main liquid inlet pipe or the liquid inlet branch pipes; the liquid inlet branch pipes are connected with the main liquid inlet pipe; each liquid distribution disc is of a circular structure with a bottom; nine to thirty eight liquid falling pipes are arranged in each liquid distribution disc and are arranged on one to four concentric circumferences; the number of the liquid distribution discs is determined by a tower diameter and liquid distribution point density; each liquid distribution disc corresponds to one liquid distribution pipe; the liquid radially flows to each liquid falling pipe after flowing out from the corresponding liquid distribution pipe; an overflow groove is formed in the side surface on the upper part of each liquid falling pipe; each liquid falling pipe penetrates out of the corresponding liquid distribution disc and extends to the respective liquid distribution point in packing. The multi-disc liquid distributor has the advantages of large number of liquid distribution points, uniform liquid distribution, light weight, convenience in installation and maintenance and the like.

Description

technical field [0001] The invention relates to the technical category of liquid distribution in gas-liquid mass transfer equipment in chemical production, in particular to liquid distributor elements in packed towers. Background technique [0002] Continuous contact gas-liquid mass transfer towers are mainly packed towers. The liquid enters from the top of the tower, and the liquid distributor distributes the liquid to the entire section of the packed tower. The liquid forms a liquid film on the surface of the filler from the liquid distribution section and flows downward along the gaps between the fillers, while the gas flows upwards between the filler gaps. The liquid film is constantly renewed in the flow, and the gas-liquid mass transfer mainly occurs on the surface of the liquid film. [0003] The uniform distribution of liquid in the packed tower can enhance the mass transfer performance of the packing, increase the uniformity of the liquid film thickness of the pac...
