Technical Field

The utility model relates to a desulphurization unit technical field specifically is a prevent blockking up continuous automatic drainage device for desulfurization flue.

Background

At present, most carbon enterprises in China mainly use wet desulphurization, smoke generated in a desulphurization link enters a horizontal flue of a draught fan through a chimney, and as the humidity of the smoke coming out of a desulphurization tower is high, moisture is condensed, and in addition, a drainage structure is lost, condensed water cannot be discharged, so that the horizontal flue is accumulated with water frequently, the corrosion of the flue is aggravated, and the service life of the flue is shortened. Secondly, because of the negative pressure in the flue gas pipeline and the need for sealing, water cannot be simply discharged through the opening, which is one of the technical difficulties. More seriously, in the area of Xinjiang, accumulated water can be frozen after the fan is stopped in winter, so that the blade of the induced draft fan is frozen and jammed, even the risk of breaking the blade exists, and the stable operation of the unit is seriously influenced. In the prior art, an inner wall guide plate is additionally arranged in a flue, so that condensed water can be automatically collected from a closed opening. However, because negative pressure exists in the flue and the influence of sealing factors is needed, the simple opening can not drain water; or only manual drainage is adopted, but manual drainage cannot solve the problems that the drainage pipe is easy to block and the drainage is not smooth due to accumulation of sediments.
