Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization towers, in particular to a spray type desulfurization tower. Background Art

[0002] In the production process of thermal power plants, environmental protection, petroleum, chemical industry, light industry, metallurgy and other industries, the flue gas generated by coal combustion contains substances such as sulfide. At present, desulfurization treatment of industrial waste gas is generally carried out using desulfurization towers. Desulfurization towers generally use spraying to carry out desulfurization treatment to prevent SO2 in coal-fired flue gas from entering the atmosphere and causing air pollution.

[0003] Patent document: CN220939939U proposes a spray-type desulfurization tower, including an air inlet and a tower body 1, wherein the air inlet is fixedly connected to the tower body 1 below, and the tower body 1 includes a fixed rod, a driven gear, a connecting rod 1, a driving gear, a connecting rod 2, a motor and a spray device above.

Compared with existing ordinary desulfurization towers, this spray-type desulfurization tower achieves all-round purification of the flue gas below the tower through the rotation of the spray device, thereby purifying the flue gas to a greater extent.

[0004] Although the device can rotate the spray device to perform all-round purification, the exhaust gas flows upward rapidly after entering the desulfurization tower, causing the exhaust gas to stay in the desulfurization tower for a shorter time, affecting the gas-liquid contact time and mixing effect.
