Example Embodiment

[0035] Example one:

[0036] The ship exhaust gas scrubbing device proposed in this embodiment, such as figure 1 As shown, it includes a scrubber body 1, and the scrubber body 1 is provided with a ship exhaust gas inlet A, an evaporative cooling zone 2, a first washing zone 3, a second scrubbing zone 4 and a ship exhaust gas outlet B from bottom to top, The ship exhaust gas inlet A is in communication with the evaporative cooling zone 2, and a first venting liquid choke 5 is arranged between the evaporative cooling zone 2 and the first washing zone 3 to allow gas to circulate but prevent liquid from flowing. Between the second washing zone 4 is provided a second venting liquid baffle 6 that allows gas to circulate but prevents liquid from flowing. The second washing zone 4 is in communication with the ship tail gas outlet B. The evaporative cooling zone 2 is equipped with an independent coolant circulation System, the evaporative cooling zone 2 uses the cooling liquid supplied by...

Abstract

The invention discloses a ship tail gas washing device, which comprises a washing tower body, and is provided with a ship tail gas inlet, an evaporative cooling area, a first and a second washing area and a ship tail gas outlet from bottom to top, the evaporative cooling area and the ship tail gas outlet. There is a first ventilation liquid blocker between the first washing area, a second air flow liquid blocker between the first washing area and the second washing area, and an independent cooling liquid circulation system in the evaporative cooling area. The area is connected with the first lye circulation system, the first washing area uses the lye supplied by the first lye circulation system to wash the ship tail gas for the first time, the second washing area is connected with the second lye circulation system, and the second The washing area uses the lye supplied by the second lye circulation system to wash the ship exhaust for the second time. The concentration of the lye supplied by the first lye circulation system and the concentration of the lye supplied by the second lye circulation system Not the same; the advantage is that it can perform cascade scrubbing of ship exhaust, and has a good desulfurization and particle removal effect.

Description

technical field [0001] The invention relates to a ship tail gas purification device, in particular to a ship tail gas washing device. Background technique [0002] The invention patent announced by China "A Ship Exhaust Gas Scrubber and Its Application Method" (Patent No. ZL201310343654.X) discloses a ship exhaust gas scrubber and its use method. The scrubber includes a scrubber body, a scrubber The body is equipped with a ship exhaust gas inlet and a ship exhaust gas outlet. The scrubber body is equipped with a main scrubbing section and a secondary scrubbing section. The liquid washing liquid circulation system, the main washing section and the auxiliary washing section are provided with a ventilation liquid blocker to allow the gas to flow and prevent the liquid from flowing. After the exhaust gas inlet of the ship passes through the main washing section and the auxiliary washing section in turn to complete the washing of the ship exhaust gas, it is discharged from the e...
