Problems solved by technology

[0004] For example, in the flue gas desulfurization system disclosed in Chinese patent CN103706237A, the desulfurization tower is sequentially provided with a flue gas washing section, an absorption section, and a recovery section along the flue gas flow direction. Although it can achieve the effect of flue gas desulfurization, it still has desulfurization Low efficiency, large volume and other problems, it is difficult to apply to ships and other special occasions that have strict requirements on desulfurization efficiency and desulfurization tower volume

Embodiment 1

[0038] Such as figure 2 As shown, a pressure regulating plate 3 for ship desulfurization is installed above the absorption section 4 in the U-shaped desulfurization tower. The tower body 1 of the desulfurization tower is a rectangular tower body with a length of 2.5 m, a width of 1.6 m, and a height of 10 m. PLC The control system 5 adjusts the rotation of the driving motor 33 through the sulfur-carbon ratio and the pressure signal fed back by the flue gas meter 6 and the pressure sensor 2 , so as to control the opening and closing angle of the blades 32 of the pressure regulating plate 3 . In this embodiment, the pressure regulating plate 3 such as figure 1 and figure 2 As shown, it includes a mounting frame 31 that penetrates up and down, a number of blades 32 that are rotatably arranged in the mounting frame 31, a drive motor 33 for driving the blade 32 to rotate, and a transmission rod 34 that connects the drive motor 33 and the blade 32 at both ends, The blades 32 are...

Embodiment 2

[0042] Such as image 3 As shown, a pressure regulating plate 3 for ship desulfurization is installed above the absorption section 4 in the I-shaped packing desulfurization tower. The tower body 1 of the desulfurization tower is a circular tower body with a radius of 2.0 m and a height of 10 m. The PLC control system 5 Adjust the rotation of the motor through the sulfur-carbon ratio and the pressure signal fed back by the flue gas meter 6 and the pressure sensor 2, and control the opening and closing angle of the blade 32 of the pressure regulating plate 3. The specific structural arrangement of the pressure regulating plate 3 is similar to that of Embodiment 1, except that in this embodiment, the width of the blades 32 is 0.3 m, the number of blades 32 is 11, and the distance between two adjacent blades 32 is set to 0.36 m. m.

[0043] When sailing in SECA and VGP sea areas, the opening and closing angle of the control blade 32 is 30° from the horizontal plane. When the sulf...

Abstract

The invention relates to a pressure regulating plate for a ship desulfurization tower, a ship desulfurization tower and a pressure regulating method thereof. The pressure regulating plate used includes a mounting frame penetrating up and down, and a plurality of rotating blades arranged in the mounting frame for driving the blades to rotate a drive assembly, and a transmission rod whose two ends are respectively connected to the drive assembly and the blades, and the blades are arranged side by side in the installation frame. Compared with the prior art, the pressure regulating plate of the present invention can be installed in a newly built desulfurization tower, and can be added to an existing desulfurization tower to obtain a better desulfurization effect, thereby improving the desulfurization efficiency of the desulfurization tower. The volume of the desulfurization tower is reduced, and the installation cost and operation cost are saved.

Description

technical field [0001] The invention belongs to the technical field of intelligent equipment manufacturing, and relates to a pressure regulating plate for a ship desulfurization tower, a ship desulfurization tower and a pressure regulating method thereof. Background technique [0002] With the implementation of the IMO sulfur limit order in 2020, more and more ships are installing desulfurization systems to remove sulfur compounds in the flue gas. The desulfurization tower is an important equipment in the desulfurization system, which has the characteristics of large volume and difficult layout. [0003] In order to obtain a better desulfurization effect, the volume of the desulfurization tower is often large, which not only wastes a lot of steel, but also is not easy to install, and will increase the navigation resistance during navigation, which in disguise increases fuel consumption. Therefore, under the premise of satisfying the demand of ship flue gas desulfurization, ...
