Abstract

The invention relates to a novel marine exhaust gas treatment device. The device comprises an exhaust gas treatment part, wherein the exhaust gas treatment part comprises a control unit, a reducing agent supply unit, a catalytic reduction unit, a particulate trapping unit and temperature sensors; the catalytic reduction unit is connected with the particulate trapping unit by the aid of a communicating pipeline; a branch is arranged on the communicating pipeline and is connected with the reducing agent supply unit; the control unit controls the particulate trapping unit, the reducing agent supply unit, the catalytic reduction unit and the temperature sensors; the catalytic reduction unit comprises multiple cylindrical catalytic reduction devices which can rotate around a rotating shaft; multiple catalytic reduction channels are arranged inside the catalytic reduction devices in the length direction at intervals and include high-temperature catalytic reduction channels, medium-temperature catalytic reduction channels and low-temperature catalytic reduction channels; and a movable decompression buffering structure is arranged between every two adjacent catalytic reduction devices. With the adoption of the device, different catalysts are switched for treatment according to the temperature of exhaust gas, so that the catalysis efficiency is maximized.

Description

technical field [0001] The invention relates to the field of ships, in particular to a novel ship tail gas treatment device. Background technique [0002] In related technologies, a large amount of fuel is required for the operation of a ship, and a large amount of by-products such as dust, nitrogen oxides, sulfur dioxide and other harmful gases will be produced when the fuel is burned. The discharge of these harmful gases into the atmosphere will seriously affect human health and hinder the growth of plants, thereby causing serious pollution of the earth's environment. However, in the related technologies, there are basically disadvantages such as large equipment cost investment and low pollutant removal efficiency. Contents of the invention [0003] In view of the above problems, the purpose of the present invention is to solve the technical problem of low removal efficiency of ship tail gas treatment. [0004] In order to solve the above-mentioned technical problems, ...
