Problems solved by technology

[0003] In order to overcome the deficiencies of the above-mentioned prior art, the object of the present invention is to provide a novel liquid distributor, aiming at the poor gas-liquid contact effect existing in the packing absorption tower, uneven water distribution in the packing absorption tower cloth water system, low operating flexibility, In order to solve the problem of poor operational stability of the sprinkler system, an absorption tower with a special three-splash nozzle is provided. Using this type of sprinkler water distribution system can improve the uniformity of water distribution, and can alleviate the air pollution caused by changes in unit load and circulating water volume. The problem of low absorption efficiency caused by uneven liquid contact enhances the stability of the entire system operation

Embodiment Construction

[0017] The present invention is further described below in conjunction with accompanying drawing.

[0018] Such as figure 1 , 2 As shown, a high-efficiency water distributor for sulfur-containing waste gas is characterized in that the water distributor is composed of two layers of systems, and the central water inlet 1 of each layer of the system is divided into four main distribution pipes 2, four main distribution pipes The main pipe 2 is evenly distributed, and each main distribution main pipe 2 is divided into a distribution branch pipe 3, and each distribution branch pipe 3 is divided into eight branches. The four main fabric main pipes 2 of the system are projected into a 45° phase-to-phase misalignment;

[0019] Such as image 3 As shown, the three-splash external thread nozzle 4 is composed of a water inlet 5, an upper shower hole 6, a middle shower hole 7, a Venturi inlet 8, a tendon 9, an upper splash tray 10, and a middle splash tray 11. , The lower splash dispe...

Abstract

A novel liquid distributor is composed of two system layers. Four main distributing pipes are arranged at a water inlet in the center of each system layer and are evenly distributed, distributing branch pipes are arranged in each main distributing pipe, all the distributing branch pipes are arrayed in an eight-branch petal mode, improved three-splashing external thread nozzles are arranged on each distributing branch pipe, and the projection of the four main distributing pipes on one system layer and the projection of the four main distributing pipes on the other system layer are staggered by 45 degrees. Absorption liquid forms a three-layer umbrella-shaped water distribution surface through the improved three-splashing external thread nozzles, the nozzles are uniformly distributed, and thus the interior of a whole absorption tower is completely and uniformly covered with the three-layer umbrella-shaped water distribution surface, so that a gas-liquid absorption surface with the largest area is achieved, water distribution uniformity is improved, the problem that the absorption efficiency is low due to gas-liquid contact nonuniformity caused by unit load changing, circulating water amount changing and other conditions is relieved, and the operating stability of a whole system is improved.

Description

technical field [0001] The invention belongs to the technical field of liquid distribution, and relates to a liquid distributor which realizes uniform distribution of materials through a special distribution nozzle, in particular to a high-efficiency liquid distributor. Background technique [0002] With the continuous improvement of people's living standards, more and more attention has been paid to environmental protection. During the combustion of fuel, pollutants such as sulfur dioxide, nitrogen oxides, and nitrogen monoxide will be produced. Wet flue gas absorption technology is the most widely used. The core of the packed absorption tower is the distribution of liquid in the tower. How to ensure the uniform flow field inside the packed absorption tower requires a large gas-liquid contact area, good gas absorption response, small pressure loss, and is suitable for large-capacity treatment. At present, the main problem in the operation of the absorption tower is that whe...
