Embodiment 1

[0036] Implementation example one is an embodiment of the method of the present invention; implementation example two is an embodiment of the device of the present invention.

[0037] Implementation example one

[0038] A method for treating ship tail gas, characterized in that it comprises the following processes:

[0039] A. The process of generating cleaning water: fresh seawater is processed to produce efficient cleaning water;

[0040] B. Atomization process: the cleaning water obtained in the A process enters the atomization device for atomization to obtain aerosol;

[0041] C. Gas-liquid reaction process: send the aerosol obtained in the B process into the gas-liquid reaction device to react with the exhaust gas of the ship, thereby removing the gas pollutants in the exhaust gas; when the aerosol contacts the solid particles in the exhaust gas, it will be on the solid particles Form a liquid, and then settle into the bottom of the reaction device together;

Abstract

The invention relates to the technical field of environment protection and discloses a device for processing boat exhaust gas, which comprises a water pump, an electro-catalysis processing unit, a storage tank, an atomization device, a gas-liquid reaction device, a solid-liquid separation device, a condensation and reflux device, an exhaust gas inlet and a pump. The water outlet of the water pump is connected with the electro-catalysis processing unit which is connected with the storage tank; one end of the pump is connected with the storage tank, and the other end is connected with the atomization device which is connected with the liquid inlet end of the gas-liquid reaction device; the exhaust gas inlet is connected with the gas inlet end of the gas-liquid reaction device; the gas outlet end of the gas-liquid reaction device is connected with the condensation and reflux device which is provided with a gas exhaust port at the upper end; and the liquid output end of the gas-liquid reaction device is connected with the input end of the solid-liquid separation device which is provided with a solid discharge port and a liquid discharge port. The invention further discloses a method for processing the exhaust gas. The invention has the advantages of low energy consumption, high efficiency, convenient installation and simple operation, the resultants from the reaction are pollution-free, and the exhaust gas removal effect is better.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a novel ship tail gas treatment method and device. Background technique [0002] Atmospheric environment is a valuable resource for human beings to survive. The destruction of atmospheric environmental resources is an irreversible process. Restoring a good atmospheric environment quality will pay more economic costs than taking measures to fundamentally prevent and control air pollution. However, in modern society, air pollution is relatively serious. The reason is that air pollutants mainly include dust particles, carbon dioxide, sulfur dioxide or nitrogen oxides. [0003] The operation of ships requires a large amount of fuel, and when the fuel is burned, a large amount of by-products, such as dust, carbon dioxide (CO 2 ), nitrogen oxides (NO x ) and sulfur dioxide (SO 2 ) and other harmful gases. The discharge of these harmful gases into the atmosphere wil...
