Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization towers, in particular to a chemical desulfurization tower which can prevent a spray nozzle from being blocked. Background Art

[0002] In the production of chlor-alkali, waste gas with a high SO2 content will be generated. If it is directly discharged into the air, it will cause serious pollution. At present, manufacturers generally use a desulfurization tower to desulfurize the waste gas. The patent publication number is CN209679858U, which discloses a desulfurization tower. The desulfurization tower is connected to the waste gas inlet and the flue gas outlet. A spray system is provided in the desulfurization tower. The spray system includes a nozzle and a spray slurry pipeline; an air intake control device is provided in the desulfurization tower, a first solenoid valve is provided at the waste gas inlet, and a second solenoid valve is provided on the spray slurry pipeline. The air intake control device is electrically connected to the first solenoid valve and the second solenoid valve. The utility model monitors the air pressure in the desulfurization tower through a U-shaped tube connected to the inside of the desulfurization tower, and presets a safety pressure value for the pressure switch arranged on the U-shaped tube. When the amount of waste gas in the desulfurization tower is too large, the air pressure in the desulfurization tower becomes strong, and the pressure switch starts to transmit a signal to the control system after being pressurized. The control system adjusts the amount of waste gas introduced and the amount of spray slurry sprayed by controlling the first solenoid valve on the waste gas inlet and the second solenoid valve on the spray slurry pipeline, so that the amount of waste gas and the amount of spray slurry in the spray tower are balanced, thereby ensuring that the flue gas with a qualified SO2 content is discharged.

[0003] The above-mentioned existing technical solutions have the following defects: the desulfurization tower uses a nozzle and a pipe to spray the exhaust gas, and is unable to filter the water. At the same time, the bottom of the nozzle cannot be brushed and cleaned. Impurities in the water are easily blocked inside the nozzle. At the same time, impurities in the exhaust gas are also easily blocked at the bottom of the nozzle, affecting the subsequent use of the user. Utility Model Content
