Tank-tank type liquid distributor

Abstract

The invention relates to a tank-tank type liquid distributor which belongs to a liquid distribution element of a filler for heat transfer and mass transfer. The tank-tank type liquid distributor mainly comprises a first-stage tank, second-stage tanks, liquid guide tanks and clamping plates, wherein each second-stage tank is of a rectangular tank constituted by side surfaces and a bottom surface, big holes and small holes are formed on the two side surfaces, the big holes are positioned over the small holes, and a plurality of multiple groups of the big holes and the small holes are formed on the second-stage tanks; the second-stage tanks are arranged side by side for forming the shape of a circle and spaced and fixed by the clamping plates; the first-stage tank is of the rectangular tank constituted by the side surfaces and the bottom surface, and holes matched with the liquid guide tanks are formed on the bottom surface; upper bottom surfaces and lower bottom surfaces of the liquid guide tanks are sealed, the small holes are formed on the side surfaces of the liquid guide tanks, and the liquid guide tanks are embedded and fixed on the holes on the bottom surface of the first-stage tank; the first-stage tank is arranged on the circular surface constituted by the second-stage tanks in parallel and vertical along the length direction, the lower parts of the liquid guide tanks go deep into tanks of the second-stage tanks, and the liquid guide tank is arranged in each second-stage tank. The tank-tank type liquid distributor can effectively improve the uniformity of gas-liquid distribution, improve the mass transfer efficiency during the separation process and realize the enhancement of industrial integration process.

Description

technical field [0001] The invention relates to a trough-type liquid distributor, which belongs to a liquid distribution element for fillers used for heat transfer and mass transfer, and is mainly used for uniformly distributing liquid on the entire tower section in a packing tower. Background technique [0002] The mass transfer equipment used in chemical industry, petroleum, light industry, metallurgy and other industrial production mainly consists of two types: packed tower and plate tower. In the packed tower, the liquid distributor is an important component, which will enter the packed tower. The liquid is evenly distributed in the cross-section of the tower, so that the liquid can evenly contact with the rising gas or another phase liquid, avoid channeling and other bad distribution phenomena, further exert the separation efficiency of the packed tower, increase the chance of two-phase contact, and ensure that the packed tower It works normally and stably. Ordinary tr...

Problems solved by technology

Ordinary trough-type liquid distributors are mostly symmetrical in structure. When the liquid spray density is small and the gas channel is large, the area occupied by the air holes is large, which makes the distribution of holes uneven, and the liquid flowing out of the liquid distributor cannot form a surface distribution.

Some liquid distributors (such as shower head liquid distributors, etc.) make the liquid fall unevenly due to the change of liquid level, which will cause the problem of uneven liquid distribution

A trough-type liquid distributor proposed by the Chinese patent (authorized notification number CN 2247048Y) is designed to design the bottom of the main tank as an inclined bottom plate with a row of small holes, and at the same time set a liquid guide plate under the bottom plate, and the top of the liquid guide plate Small holes are opened, and the lower part is divided into several branches, so that the liquid poured onto the liquid guide plate forms multiple drop point distributions to meet the requirements of the small liquid flow rate for the initial distribution rate. However, since the distribution holes are set at the bottom, Part of the distribution holes are easily blocked by solid particles and suspended matter, resulting in uneven distribution of liquid
