A scientific research vessel with an anti-corrosion and noise-reducing chimney

Abstract

The invention discloses a scientific investigation ship with an anti-corrosion and noise-reducing chimney, which includes a hull and a chimney for discharging exhaust gas arranged on the hull, and a conversion device arranged at the central axis of the chimney for converting the kinetic energy of the exhaust gas into electric energy device, an internal cooling device installed on the inner wall of the chimney to reduce the internal temperature of the chimney and smoke, a sound-absorbing device used to reduce the noise of the chimney, an external cooling device installed on the outer wall of the chimney, and an insulation layer installed on the surface of the external cooling device. For the circulation purification device and the controller that purify and circulate the cooling liquid, the exhaust gas generated by the main engine enters the chimney through the exhaust pipe, and the high-speed exhaust gas pushes the conversion device to work, while the noise reduction device performs noise reduction. A first sensor that detects temperature. The invention effectively reduces the internal and external temperatures of the chimney through multi-stage cooling, and performs visual real-time control and adjustment of the temperature of the chimney through a detection and control system, thereby effectively solving the problem of high-temperature corrosion.

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;
