Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of production machinery, and in particular relates to an overflow pipe structure of a desulfurization tower. Background Art
[0002] At present, after the wet flue gas desulfurization absorption tower of a thermal power plant has been running for a period of time, foam will mostly be produced in the tower. The foam will be discharged out of the tower through the auxiliary overflow pipe of the absorption tower, which not only pollutes the environment, but also easily causes corrosion and damage to the absorption tower wall and surrounding facilities, reducing its service life and seriously affecting the economic and environmental operation of the equipment.
[0003] The existing solution is usually to open the overflow port below the lowest liquid level of the absorption tower to avoid the floating foam area, and to eliminate the foam by adding appropriate defoaming agents. However, it was found through use that since the overflow pipe port is below the liquid level, there is also slurry in the overflow pipe. Although the foam generated on the upper surface of the slurry in the tower generally rarely enters the overflow pipe, when the liquid level of the desulfurization tower slurry pool fluctuates greatly, the foam in the slurry is easy to enter the liquid seal water tank through the high overflow pipe, resulting in low liquid level overflow. Utility Model Content
[0004] In view of the above-mentioned technical problems, the utility model provides a desulfurization tower overflow pipe structure to solve the problem of low liquid level overflow in the existing desulfurization absorption tower. The desulfurization tower overflow pipe structure can effectively prevent foam from flowing into the overflow pipe and prevent low liquid level overflow.
[0005] The utility model discloses a desulfurization tower overflow pipe structure, comprising a desulfurization tower body, an overflow pipe, a fan, a liquid seal structure and a baffle, wherein an overflow port is provided on the side wall of the desulfurization tower body, one end of the overflow pipe is connected to the overflow port, the other end of the overflow pipe extends out of the desulfurization tower body and is connected to the liquid seal structure, the baffle is arranged around the overflow port, and a columnar space with upper and lower openings is enclosed between the baffle and the side wall of the desulfurization tower body, a plurality of through holes are provided on the baffle, the fan is fixed on the side wall of the desulfurization tower body and is located at the upper part of the columnar space, and the fan faces the columnar space.
[0006] Furthermore, the baffle is an arc-shaped plate.
[0007] Furthermore, the liquid sealing structure is a liquid sealing groove.
[0008] The overflow pipe structure of the desulfurization tower is provided with a baffle on the outer periphery of the overflow port to form a columnar space with upper and lower openings, and a plurality of through holes are provided on the baffle. When the liquid level of the desulfurization tower is really high, the overflow slurry passes through the baffle and is discharged from the overflow pipe into the liquid seal structure, while when the liquid level is low, the baffle can prevent the foam from entering the overflow port through the surge. At the same time, the fan blows air downward from the top of the columnar space, which, on the one hand, plays a role in defoaming the inside of the columnar space, and on the other hand, effectively prevents the foam from entering the columnar space through the through holes through the wind force.
