Description

Technical Field

[0001] The present application relates to the technical field of cement production equipment, and in particular to a kiln tail humidification tower. Background Art

[0002] The main function of the humidification tower in the cement plant process is to humidify the flue gas at the tail of the dry kiln, reduce the resistivity of high-temperature dust in the exhaust gas, improve the efficiency of the electric dust collector at the tail of the kiln, protect the environment, recycle dust, and reduce material consumption.

[0003] In the related art, after the flue gas enters the humidification tower, water is generally transported into the water pipe through the pump body, and the water pipe in the humidification tower sprays the flue gas to reduce the resistivity of the dust in the flue gas. In order to enable the sprayed water or water mist to cover a larger cross-sectional area, multiple atomizing nozzles are usually installed on the water spray pipe. However, when the amount of flue gas to be purified is small, the above-mentioned spraying method will cause a waste of water resources and affect the efficiency of water resource utilization. If the water flow delivery per unit time is reduced, the pressure of the atomizing nozzle will be affected, and then the spraying area of ​​the atomizing nozzle will be affected, and then the purification rate of the flue gas will be affected.
