Scientific research ship with anti-corrosion and noise-reduction chimney

Abstract

The invention discloses a scientific research ship with an anti-corrosion and noise-reduction chimney. The scientific research ship comprises a ship body and the chimney arranged on the ship body andused for exhausting waste gas, and further comprises a conversion device arranged at the central axis position of the chimney and used for converting kinetic energy of the waste gas into electric energy, an internal cooling device arranged on the inner wall of the chimney and used for reducing the internal temperature of the chimney and smoke dust, a silencing device used for reducing the noise ofthe chimney, an external cooling device arranged on the outer wall of the chimney, a heat insulation layer arranged on the surface of the external cooling device, a circulating purification device used for purifying and recycling cooling liquid, and a controller. The waste gas generated by a main engine enters the chimney through a smoke exhaust pipeline, the high-speed waste gas pushes the conversion device to work, meanwhile, the silencing device conducts noise reduction and silencing, and a first sensor used for detecting the temperature is arranged at an inlet of the chimney. According tothe scientific research ship, the internal temperature and the external temperature of the chimney are effectively reduced through multi-stage cooling, the temperature of the chimney is visually controlled and adjusted in real time through a detection control system, and the high-temperature corrosion problem is effectively solved.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a scientific investigation ship with an anti-corrosion and noise reduction chimney. Background technique [0002] With the development of the country's economy, ships have become one of the main means of transportation by virtue of the advantages of large capacity, low freight and international transportation. The flue gas temperature is high and the pressure is high, the exhaust temperature of the main engine of the ship and the diesel engine of the power station is often as high as 500 ℃, and the surface of the exhaust pipe is easily corroded and damaged in the harsh environment of high temperature oxidation and seawater salt spray erosion, reducing the service life; In addition to high temperature and high pressure, the exhaust process is accompanied by huge noise, which has a huge impact on the health of the crew and has become the main source of ship noise. [0003] In order ...

AI Technical Summary

Problems solved by technology

[0004] Although the above-mentioned invention can reduce the temperature of the outer surface of the chimney and reduce the amount of smoke and dust, there are still the following problems: 1. The cooling effect is limited only through the thermal fluid circulation, and the temperature drop cannot be accurately controlled and adjusted, and the cooling effect is not obvious; 2. Due to The cooling effect is not obvious and cannot effectively solve the problem of high temperature corrosion of the chimney; 3. The problem of exhaust noise cannot be effectively solved; 4. The energy recovery rate is not high;
