Abstract

The invention discloses a diffusion device for discharging waste water from a ship tail gas desulfurization system. The diffusion device comprises a cylindrical body, wherein a plane, a concave surface, a central diffusion hole and a plurality of peripheral diffusion holes are formed in the cylindrical body. The central diffusion hole and a plurality of the peripheral diffusion holes are formed inthe cylindrical body, and a certain hole elevation angle is arranged between the central line of the peripheral diffusion holes and the axis of the cylindrical body, so that waste water diffused by the peripheral diffusion holes rapidly diffuses to the peripheral direction, the mutual concentration superposition of waste water diffusion is less; waste water discharged by a plurality of the peripheral holes diffuses out along the respective peripheral directions, and thus drainage obstruction interference between the peripheral diffusion holes can be reduced, and the drainage resistance can bewell reduced, so that the diffusion device can achieve the purpose of effectively diffusing waste water under lower resistance and meet the requirements of IMO MPEC.

Description

technical field [0001] The invention belongs to the technical field of ship tail gas washing, in particular to a diffusion device for discharging waste water from a ship tail gas desulfurization system. Background technique [0002] With the development of the international shipping industry and ocean-going shipping, exhaust emissions from ships have become the main source of pollution in coastal areas. The pollution of the atmospheric environment caused by SOX in the exhaust gas of ships has aroused widespread concern in the international community. At present, ship exhaust gas scrubbing and desulfurization systems (EGCS) are mainly divided into wet scrubbing and desulfurization systems, which almost occupy the entire ship scrubbing and desulfurization market. [0003] There are three different implementation forms of the ship flue gas wet scrubbing system: ① seawater scrubbing exhaust gas (open system), using the alkalinity of seawater to absorb SO in the exhaust gas X ,...
