Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of desulfurization equipment, in particular to a flue gas gathering ring used for desulfurization equipment. Background Art
[0002] Desulfurization equipment refers to the spray tower used for waste gas desulfurization. According to the working principle, it is divided into circulating water spray tower, alkali spray tower and acid spray tower. When the waste gas enters from the bottom of the tower, it will come into contact with the liquid sprayed from the spray tower. After contact, the sulfur in the waste gas reacts with the liquid and remains in the spray tower, so that the waste gas can be discharged into the atmosphere normally.
[0003] The air inlet of the existing desulfurization spray tower is set on the side. When the exhaust gas enters the spray tower, it will float upward with an inclined trend. The exhaust gas occupies a small area in the spray tower and cannot fully contact with the sprayed liquid, which will cause waste of spray liquid and increase cost consumption. It is very inconvenient. Therefore, a flue gas gathering ring for desulfurization equipment is designed. Utility Model Content

[0009] Furthermore, the air outlet valves are installed in a circular shape and equidistantly distributed on the surfaces of the smoke gathering outer ring and the smoke gathering inner ring, and are connected to the first air chamber and the second air chamber. The diffusion holes are opened on the surfaces of the smoke gathering outer ring and the smoke gathering inner ring, and are located between two adjacent first air chambers and the second air chambers.
[0010] Furthermore, an air inlet penetrating the smoke collecting outer ring is formed at one end of the inner wall of any of the first air chambers away from the smoke collecting inner ring. The air inlet is trapezoidal in shape, with the larger end facing the outside of the smoke collecting outer ring. A flow guide is installed in the air inlet.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.
[0022] See also Figure 1-4 The utility model discloses a flue gas gathering ring for a desulfurization device, comprising a smoke gathering outer ring 1 and a smoke gathering inner ring 2 arranged on the inner side of the smoke gathering outer ring 1, a chamber structure for uniform diffusion of exhaust gas is arranged between the inner sides of the smoke gathering outer ring 1 and the smoke gathering inner ring 2, an outlet valve 4 and a diffusion hole 5 for uniform exhaust gas discharge are arranged on the outer sides of the smoke gathering outer ring 1 and the smoke gathering inner ring 2, the outlet valve 4 is connected to the chamber structure, and the smoke gathering outer ring 1 is provided with a connector for installation on the inner side of the desulfurization device.
[0023] See also Figure 4 The chamber structure is composed of a first air chamber 11, a second air chamber 21 and an air flow channel 3. The first air chamber 11 is opened on the inner side of the smoke gathering outer ring 1, and the second air chamber 21 is opened on the inner side of the smoke gathering inner ring 2. The first air chamber 11 and the second air chamber 21 are both distributed in a circular shape with equal distances around the center of the smoke gathering inner ring 2. The air flow channel 3 is annular and opened between the smoke gathering outer ring 1 and the smoke gathering inner ring 2. The air flow channel 3 connects the first air chamber 11 and the second air chamber 21. A large number of the first air chamber 11 and the second air chamber 21 are set, which can cooperate with the air outlet valve 4. When the exhaust gas is discharged from the smoke gathering outer ring 1 and the smoke gathering inner ring 2, the exhaust gas is evenly distributed on the inside of the desulfurization equipment to avoid the waste of ineffective dripping of the spray liquid.
[0024] See also Figure 2 The outlet valves 4 are installed in a circular shape and equidistantly distributed on the surface of the smoke collecting outer ring 1 and the smoke collecting inner ring 2, and are connected to the first air chamber 11 and the second air chamber 21. The diffusion holes 5 are opened on the surface of the smoke collecting outer ring 1 and the smoke collecting inner ring 2, and are located between two adjacent first air chambers 11 and the second air chambers 21. The setting of the diffusion holes 5 can make the exhaust gas discharged from the outlet valve 4 pass through the smoke collecting outer ring 1 and the smoke collecting inner ring 2 evenly and float upward to react with the spray liquid. At the same time, it can also allow the spray liquid to pass through the smoke collecting outer ring 1 and the smoke collecting inner ring 2 and be discharged along the bottom of the desulfurization equipment.
[0025] See also Figure 1An air inlet 12 penetrating the smoke collecting outer ring 1 is provided at one end of the inner wall of any first air chamber 11 away from the smoke collecting inner ring 2. The air inlet 12 is trapezoidal in shape, and the larger end faces the outside of the smoke collecting outer ring 1. A flow guide 7 is installed in the air inlet 12.
[0026] See also Figure 1 The connecting piece is composed of a sealing ring 6 and a sealing interface 61. The sealing ring 6 is installed on the outside of the smoke collecting outer ring 1. The sealing interface 61 is arranged on the outside of the sealing ring 6 and is connected to the air inlet 12. The sealing interface 61 is rectangular on the side away from the smoke collecting inner ring 2. The setting of the sealing ring 6 facilitates the installation in contact with the inner wall of the desulfurization equipment, and the sealing interface 61 can seal the air inlet opening on the side of the desulfurization equipment to avoid leakage of exhaust gas during the flow process, which affects the gathering effect of the exhaust gas flowing to the smoke collecting outer ring 1 and the smoke collecting inner ring 2.
[0027] When the exhaust gas needs to be desulfurized, the exhaust gas is first introduced into the air inlet opening of the desulfurization equipment, and then the exhaust gas enters the first air chamber 11 of the smoke collecting outer ring 1 along the sealing interface 61 and the guide member 7 in the air inlet 12 of the smoke collecting outer ring 1, and then gradually flows to the other first air chambers 11 and the second air chamber 21 through the air flow channel 3. During the process, the exhaust gas will be discharged from the smoke collecting outer ring 1 and the smoke collecting inner ring 2 through the air outlet valve 4, evenly distributed in the desulfurization equipment, and float upward through the diffusion hole 5 to react with the spray liquid of the desulfurization equipment.
