[0002] A large amount of water-containing flue gas will be generated during the slag stewing process in the hot pouring room. The existing way to discharge the wet flue gas in the hot pouring room is to let it overflow from the side windows around the plant by the rising force of the flue gas itself. Since there is a relatively high distance between the side windows of the plant and the ceiling of the plant, a large amount of flue gas often accumulates on the top of the plant and is not completely discharged. In addition, heavy rain or windy weather will also cause the flue gas to be affected by airflow and wind, resulting in the inability to discharge the flue gas. A large amount of flue gas enriched inside the plant poses a major safety hazard. First, due to the high humidity and sulfur content of the flue gas, the failure rate of electrical equipment and electrical components is high, and the steel structure plant is seriously corroded; second, the enriched flue gas blocks the view of the overhead crane driver, affecting the normal tank turning and hammering operations.

[0010] Beneficial Effects
[0011] Compared with the prior art, the utility model has the following advantages:
[0012] The utility model discloses a ventilation tower for exhausting wet flue gas from a hot-spraying room. The flue gas enriched on the top of the hot-spraying room enters the air flow well through its own rising force, and then enters the air flow channel through the exhaust window. The flue gas goes up along the air flow channel, passes through the exhaust port and is discharged from the exhaust pipe. During this period, a desulfurization device is added.

[0016] See also Figure 1As shown, a ventilation tower for exhausting wet flue gas from a hot-splashing room of the utility model comprises an airflow shaft 1, which is installed on a roof 3 of the hot-splashing room, and the bottom of the airflow shaft 1 is connected to the inside of the hot-splashing room, a top sealing layer tower cover 4 is provided on the top of the airflow shaft 1, an exhaust window 5 for flue gas circulation is provided on the side wall of the airflow shaft 1, an opening layer tower cover 8 is provided on the outside of the airflow shaft 1 to wrap it, an airflow channel 9 is provided between the opening layer tower cover 8 and the airflow shaft 1, an exhaust port 10 is provided on the top of the opening layer tower cover 8, and a desulfurization device 2 is provided on the exhaust port 10, the flue gas enriched on the top of the hot-splashing room enters the airflow shaft through its own rising force, and then enters the airflow channel 9 through the exhaust window 5, and the flue gas flows along the airflow channel 9 to It goes up and is discharged from the exhaust pipe 21 after passing through the exhaust port 6. During this period, a desulfurization device 2 is added. When the flue gas is discharged to the exhaust pipe 21, the water pump 24 draws the desulfurizer into the spray pipe 23 and sprays it out through the atomizing spray head 22, so that the desulfurizer and the flue gas are mixed and reacted, thereby achieving the effect of desulfurization, thereby reducing air pollution and protecting the environment. The flue gas is effectively discharged through the ventilation tower, thereby solving the existing problem that wet flue gas is enriched inside the factory building, resulting in a high failure rate of electrical equipment and electrical components, serious corrosion of steel structure factory buildings, and flue gas enrichment, which blocks the line of sight of the overhead crane driver and affects the normal tank turning and hammering operations, and effectively prolongs the service life of electrical equipment, electrical components and steel structure factory buildings.
[0017] Specifically, the desulfurization device 2 includes an exhaust pipe 21, a spray pipe 23, a water pump 24 and a plurality of atomizing spray heads 22. The exhaust pipe 21 is installed on the exhaust port 10. The spray pipe 23 is arranged on the outside of the exhaust pipe 21. The atomizing spray head 22 is installed on the exhaust pipe 21, and the atomizing spray head 22 is connected to the spray pipe 23. The spray pipe 23 is connected to the output end of the water pump 24. The input end of the water pump 24 is connected to a water bucket 25. The water bucket 25 contains a desulfurizer. The water pump 24 draws the desulfurizer into the spray pipe 23 and sprays it out through the atomizing spray head 22, so that the desulfurizer mixes and reacts with the flue gas, thereby achieving a desulfurization effect.
[0018] Preferably, the spray pipe 23 is spirally wrapped around the outside of the exhaust pipe 21, and multiple atomizing spray heads 22 are evenly arranged on the spray pipe 23 at equal distances, so that the spray of the atomizing spray head 22 is more uniform, and the mixing effect of the flue gas in the exhaust pipe 21 is better, thereby improving the desulfurization effect.
[0019] Furthermore, the top sealing layer tower cover 4 is a conical structure that is narrow at the top and wide at the bottom, so that rainwater passes through the conical top sealing layer tower cover 4 and falls on the roof 3 of the hot-spraying room factory building, and is discharged to the outside through the drain port 6, and will not enter or flow back into the hot-spraying room factory building.
[0020] Furthermore, a drainage port 6 is provided between the open layer tower cover 8 and the roof 3 of the hot-spraying room, for draining water droplets formed by rainwater or spray.
[0021] Furthermore, the drainage outlet 6 is connected to a drainage trough 7, which is arranged obliquely along the roof 3 of the hot-spraying room, so that rainwater can be more concentrated when drained, avoiding scattered drainage on the roof 3 of the hot-spraying room, and reducing the damp area below.
[0022] When the wet flue gas exhaust ventilation tower of the hot-spraying room of the present embodiment is in use, the flue gas enriched on the top of the hot-spraying room enters the air flow well through its own rising force, and then enters the air flow channel 9 through the exhaust window 5. The flue gas goes up along the air flow channel 9, passes through the exhaust port 6 and is discharged from the exhaust pipe 21. During this period, a desulfurization device 2 is added. When the flue gas is discharged to the exhaust pipe 21, the water pump 24 draws the desulfurizer into the spray pipe 23, and sprays it out through the atomizing spray head 22, so that the desulfurizer and the flue gas are mixed and reacted, thereby achieving the effect of desulfurization, thereby reducing air pollution and protecting the environment. The flue gas is effectively discharged through the ventilation tower, thereby solving the problems that the existing wet flue gas is enriched inside the factory building, resulting in a high failure rate of electrical equipment and electrical components, serious corrosion of the steel structure factory building, and flue gas enrichment, blocking the line of sight of the overhead crane driver, and affecting the normal tank turning and hammer smashing operations, and effectively extending the service life of the electrical equipment, electrical components and steel structure factory building.

It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which will not affect the effect of the implementation of the present invention and the practicality of the patent.
