Abstract

The invention discloses a device and method for jointly removing marine waste gas pollutants. The device comprises a gas inlet pipeline, wherein the gas inlet pipeline is connected with a reactor according to a set angle; a plurality of draining blades are arranged inside the reactor, and are arranged in a spiral downward state in the reactor to guide waste gas to move downward; the mounting anglebetween the draining blades and the reactor is adjustable in a setting range; a particle collection opening is formed in the bottom of the reactor; an exhaust passage is formed in the center inside the reactor, an outward groove is formed in the bottom of the exhaust passage; the upper part of the exhaust passage is extruded from the top of the reactor; and a detachable filter device is arrangedin the cavity of the upper part of the exhaust passage; a reducer nozzle is arranged in the cavity of the lower part of the exhaust passage, and is connected with the tail end of a reducer delivery pipeline; and the reducer delivery pipeline penetrates through the exhaust passage and the reactor and is connected with a reducer delivery source. The device can solve the problems of large size and distribution difficulty of a traditional waste gas treatment device.

Description

technical field [0001] The invention relates to the field of ship waste gas treatment, in particular to a combined removal device and method for ship waste gas pollutants. Background technique [0002] The shipping industry undertakes 90% of the world's trade and transportation. Ship emissions are characterized by mobility, borderlessness, and cross-regionality. China's shipping industry has developed rapidly, but it started late in terms of energy saving and emission reduction of marine diesel engines and insufficient technical accumulation. For this reason, it has been lagging behind developed countries. [0003] In the prior art, most exhaust gas treatment devices have complex structures and large volumes, making it difficult to arrange them on marine diesel engines. "A waste gas treatment device and waste gas treatment method" mentioned in the patent CN106178904A includes more than four storage tanks, more than two reactors and various pipe fittings and valves. Although...
