Tail gas smoke eliminating device and method for offshore wind power self-elevating type installing platform generator set

Abstract

The invention discloses a tail gas smoke eliminating device and method for an offshore wind power self-elevating type installing platform generator set. The device comprises a buffering chamber, a smoke eliminating chamber and a connecting pipe fitting. One end of the connecting pipe fitting is connected with the lower portion of the side wall of the buffering chamber, and the other end of the connecting pipe fitting is connected with the top of the smoke eliminating chamber. An air inlet is formed in the upper portion of the side wall of the buffering chamber, a spraying mechanism is arrangedon the top of the buffering chamber, and a discharging port is further formed in the bottom of the buffering chamber. The upper portion of the side wall of the smoke eliminating chamber is provided with a water inlet and an overflow port, an exhaust pipe is arranged on the top, and a water draining opening and a stop valve are arranged at the bottom. The end, connected with the smoke eliminatingchamber, of the connecting pipe fitting goes deep into the smoke eliminating chamber from the top of the smoke eliminating chamber. The method comprises the following steps that tail gas of the generator set is sequentially guided into the buffering chamber and the smoke eliminating chamber, and buffering chamber spraying and smoke eliminating chamber washing treatment are sequentially conducted on tail gas through cold seawater. Compared with the prior art, the scheme has the effects of smoke eliminating, tail gas cooling and air pollution reducing.

Description

technical field [0001] The invention relates to the technical field of marine engineering, in particular to an exhaust smoke elimination device and method for an offshore wind power self-elevating installation platform generator set. Background technique [0002] With the rapid development of international trade and shipping industry, the tonnage of ships continues to increase, and the air pollution and greenhouse effect caused by ship exhaust gas fueled by petroleum products have been highly valued worldwide. The main components of exhaust gas from marine diesel engines are: CO 2 +H 2 O+CO+NO X +SO 2 +C X h X More than 10 kinds of substances such as +PM, ​​most of them are poisonous to human beings, and some are even carcinogens. Countries around the world have made stricter regulations on their emissions. At present, most marine diesel engines have specific exhaust emission requirements, and the emissions of carbon dioxide (including CO) and nitrogen oxides of sulfur...

AI Technical Summary

Problems solved by technology

[0003] At present, the engine rooms of offshore wind power installation ships are all located under the main deck in the middle of the hull. The air pipe and the muffler pass through the top of the chimney and are directly discharged into the air, which usually leads to the following problems: 1. The exhaust gas of the generator set causes the appearance of the pile legs and the pile frame to turn black; 2. The high-temperature gas discharged affects the pile The life of the top-of-rack equipment and the life of the nearby painted surface; 3. Untreated exhaust gas pollutes the air
