Problems solved by technology

The disadvantage is still that the amount of waste gas treatment is small, the cost of waste gas treatment is high, and different types of waste gas treatment devices must be installed for different types of inert gas, which greatly increases the operating cost of the ship

Abstract

The invention relates to a device for treating an exhaust gas of a tank ship and preparing an inert gas from the exhaust gas. The device comprises a pipeline combustor, a catalytic conversion device, a cooler and a CO2 washing tower, which are sequentially connected with one another through a pipeline to form an exhaust gas treatment device, wherein the cooler is also connected with an O2 washing tower, a dryer, a copper net deaerating device and an inert gas storage cabinet to form a device for preparing the inert gas from the exhaust gas. The invention further relates to a technology for treating the exhaust gas of the tank ship and preparing the inert gas from the exhaust gas. Compared with the prior art, the device and the technology have the advantages that the exhaust gas treatment device is combined with the device for preparing the inert gas from the exhaust gas through the pipeline combustor, the catalytic conversion device and the cooler; the discharged gas can be relatively clean by the CO2 washing tower and the O2 washing tower in the exhaust gas treatment device; meanwhile, the exhaust gas of the ship can be effectively treated by the device for preparing the inert gas from the exhaust gas; the components in the exhaust gas reach the requirements of the inert protective gas in an oil tank; and the treatment cost of the exhaust gas is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of oil tanker exhaust gas treatment, and in particular relates to a device and a process for inerting treatment of exhaust gas in an oil tanker and ship exhaust gas. Background technique [0002] At present, the existing generators for producing inert protective gas for oil tankers include flue gas type, independent type, multi-functional type, etc., each type of inert protective gas generator has its own structural characteristics and certain scope of application. Although the flue gas type inert protective gas generator has good economic performance, it only uses the boiler exhaust gas as the source and cannot treat the pollutants in the exhaust gas, so the exhaust gas cannot reach the International Maritime Organization (IMO) MARPOL73 / The emission requirements in the amendments to the 78 Convention; independent inert protective gas generators, the advantage of this device is that it can control the purit...
