Abstract

The invention discloses a modular system for comprehensive treatment of ship engine waste gas. The system comprises a desulfurization and denitrification module, a chemical agent and supply module, achemical agent heating module, a wastewater/slag treatment module and a system pressure adjusting module; a seawater pump is adopted as a main pipeline force device; the desulfurization and denitrification module is a pneumatic reaction washing tower; a pressure adjusting module in the pneumatic reaction washing tower is an injection fan; a cavitation spraying system is arranged at the top of thepneumatic reaction washing tower and comprises a cavitation nozzle, a pump, a pipeline and a liquid medium; an ejector fan is arranged on one side of the pneumatic reaction washing tower, and an electrostatic dust collection device is arranged at the bottom of the pneumatic reaction washing tower; the chemical agent heating module comprises a heat pipe type waste heat recovery device and a heat exchanger; the chemical agent and supply module comprises a chemical agent storage box and a chemical agent mixing tank; and the wastewater/slag treatment module comprises a water treatment device and areaction waste slag storage tank. Efficient desulfurization, denitration, dust removal and carbon removal can be achieved, the installation cost can be controlled, the installation space is saved, and the universalization rate of functional components is increased through modular design.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a desulfurization, denitrification, decarburization and dust removal system for modular ship engine waste gas. 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 air pollution in coastal areas, especially in ports. The fuel used in marine power plants is heavy oil with high viscosity, high sulfur content, and high carbon residue. Among the gaseous emissions produced by it, SOx occupies a large proportion, and it is easy to combine with water in the air to form acid rain and acid rain. Fog and chemical smog are one of the main acid gases that cause air pollution, causing great harm to the ecological environment of the earth and human health. [0003] At present, domestic and foreign are vigorously researching the scrubbing system for exhaust gas...
