Description

technical field [0001] The invention relates to a regeneration tower in the desulfurization section of coking production, in particular to an electric liquid level adjustment device for the desulfurization regeneration tower and a working method for the regeneration tower installed with the electric liquid level adjustment device. Background technique [0002] The regeneration tower is the key equipment of the coke oven gas wet desulfurization process, and the liquid level adjustment device at the top of the tower has a great influence on the regeneration effect. Initially, the liquid level regulating device 3 is fixed on one side of the regeneration tower through a bracket 10, such as figure 1 shown. With the increase of the processing capacity, the structure and weight of the automatic adjustment device 3 and the support 10 all increase accordingly. Not only is it difficult to arrange the operation platform, but the eccentric load of the regeneration tower is also increas...

Problems solved by technology

However, after the liquid level regulating device 3 is moved to the inside of the foam tank 1, the increase of the liquid level regulating pipe indirectly leads to the increase of the diameter of the foam tank 1; in addition, a horizontal ∪ structure 11 needs to be separately provided to ensure the desulfurization overflowing from the liquid level regulating pipe. The liquid is completely isolated from the foam tank 1 and the desulfurization liquid tank 2. During construction, it is necessary to cut the cylinder body of the desulfurization liquid tank 2 to fix the horizontal ∪-shaped structure 11, making the construction more difficult, such as image 3 As shown; in addition, the liquid level regulating pipe moves up and down inside the guide rail formed by three angle steels 13 to adjust the liquid level. The angle steels 13 and the connecting plate 12 are fixed by bolts, and the connecting plate 12 is welded on the inner wall of the horizontal ∪ structure 11. Due to the limited operating space, There is considerable difficulty in the actual construction process of the guide rail

There are many impurities contained in the desulfurization liquid, which will form deposits at the bottom of the desulfurization liquid tank after long-term operation, which is difficult to clean

[0004] The liquid level regulating pipe of the conventional liquid level regulating device 3 relies entirely on manual control (such as driving it to move up and down through zippers and pulleys), and the liquid level regulating pipe weighs more than 300kg, and the adjustment is very laborious; and the liquid level regulating device is located in the regeneration tower The top needs to be manually climbed up and down when adjusting, which is time-consuming and laborious, and the response is slow, which affects production
