Description

Technical Field

[0001] The utility model relates to the technical field of purification tower devices, in particular to an automatic discharge device and a discharge system for activated carbon desulfurization and denitration. Background Art

[0002] The activated carbon desulfurization and denitrification method is to introduce the flue gas after sintering electrostatic precipitator into the purification tower through a booster fan. In the tower, the flue gas contacts with the activated carbon in a countercurrent manner. The SO2 in the flue gas is adsorbed by the activated carbon, and NO X It reacts with NH3 and is reduced to N2, which is discharged through the chimney with the flue gas. The activated carbon that adsorbs SO2 enters the regeneration tower through the material circulation system, and is analyzed at high temperature. The analyzed SO2 enters the acid-making system, and the activated carbon returns to the purification tower after regeneration. The dust in the entire system enters the raw material warehouse through the ash conveying system to be sintered and utilized, and the acid-making tail gas returns to the entrance of the purification tower to be purified again, achieving zero waste emissions.

[0003] Removal of NO in exhaust gas by flue gas purification X During the denitrification process, ammonia water needs to be sprayed, because NH3 can easily combine with Cl and S elements to form ammonia crystals such as NH4Cl or (NH4)2SO4, which adhere to the surface of activated carbon. This can easily cause the gas distribution grid or denitrification layer to be blocked by activated carbon, causing uneven airflow distribution. Over time, it can easily cause the pressure difference in the purification tower to increase, so the inside of the purification tower must be cleaned.

[0004] The denitrification layer has a small space. There are 4 compartments where the activated carbon is accumulated. There is a set of steel plate stops between every two compartments. The distance between the ground and the bottom of the steel plate is only 40cm. There are also multiple chute pipes. Some areas have serious ammonia crystallization and need to be cleaned once every 3 months on average. The internal cooling speed is slow. Normally, it takes 2 days to stop before personnel can enter for thorough cleaning. The space is small and the cleaning process is difficult. It takes at least 7-10 days to complete the cleaning.

[0032] The utility model discloses an automatic discharging device for desulfurization and denitration of activated carbon 12, wherein a vibrating grille 3 is connected to the inside of a tower body 13 through a first hinge 4, and is spaced from top to bottom and is successively arranged close to the axis of the tower body 13 to form a tapered narrowing, and each grille has a spacing, and adjacent vibrating grilles 3 have an overlapping area in the vertical direction at each angle, and the vibrating grille 3 is vibrated by a driving motor, and the vibration force causes ammonia crystals to automatically fall onto a discharging plate, and when a gravity detector 7 reaches an activity limit, it is automatically opened for discharging, so that ammonia crystal substances such as NH4Cl or (NH4)2SO4 efficiently fall off the vibrating grille 3, reducing the influence of the crystal substances on the desulfurization and denitration effects, and the accommodating space is used to receive and accommodate the crystal substances vibrated off the vibrating grille 3, and the discharging mechanism automatically adjusts the bottom plate 6 and the inclination angle, so that the crystal substances can be discharged smoothly, and the control is convenient, the performance is reliable and the operation is stable, the ammonia crystal problem in the gas distribution grille 2 area is solved, the adsorption performance of the purification tower is restored in time, and the flue gas treatment effect is ensured, and the labor intensity and difficulty of ammonia cleaning can be greatly reduced while optimizing the existing process technology.

[0033] The vibration mechanism and the discharge mechanism are multi-layered, and the multi-layer adjacent vibration mechanisms and discharge mechanisms are connected to continuously process the crystalline materials at the same level to improve the desulfurization and denitrification efficiency.
