Embodiment Construction

[0034] The technical solution of the present invention is specifically described below in conjunction with the accompanying drawings. It should be pointed out that the technical solution of the present invention is not limited to the implementation described in the examples. Those skilled in the art refer to and learn from the content of the technical solution of the present invention. Improvements and designs made on the basis of the invention shall belong to the protection scope of the present invention.

[0035] Such as figure 1 Shown, the present invention is further described below in conjunction with accompanying drawing.

[0036] Atmospheric window 8μm~14μm (1250cm -1 ~714cm -1 ) within the spectral range, sulfur dioxide in the 8.3μm ~ 9.1μm (1200cm -1 ~1100cm -1 ) has obvious absorption peaks in the spectral range, while there is no absorption in the rest of the spectral range. In the natural environment, the characteristic absorption range of sulfur dioxide is 8....

Abstract

The present invention discloses an all-time marine sulfur dioxide gas discharge remote measurement apparatus including a thermal infrared camera, at least two band-pass filters, a thermal infrared area array detector, a processor and a display, the at least two band-pass filters are arranged at the rear part of the thermal infrared camera, the thermal infrared area array detector is arranged at the rear part of the at least two band-pass filters, the thermal infrared area array detector is connected with the processor, and the processor is connected with the display. The beneficial effects are that: (1) through use of passive thermal infrared differential imaging technology, a marine sulfur dioxide gas discharge smoke plume image can be accurately obtained, and 24-hour all-time work can be achieved; (2) marine sulfur dioxide gas discharge amount can be remotely measured, the possibility of excessive emissions can be determined, the basis is provided for law enforcement personnel, and the supervision efficiency is improved; and (3) the all-time marine sulfur dioxide gas discharge remote measurement apparatus is small in volume and easy to carry, and placement places can be flexibly arranged according to need.

Description

technical field [0001] The invention relates to a remote measurement method and equipment for all-day emission of sulfur dioxide gas from ships, belonging to the technical field of gas monitoring. Background technique [0002] In recent decades, with the continuous development of the shipping economy, the number and tonnage of ships powered by diesel engines have increased significantly. However, due to the long-term use of cheap heavy residual oil with high sulfur content as fuel, the exhaust gas from ships contains a large amount of sulfur dioxide, causing serious air pollution, which has attracted great attention from the international community. In the face of severe air pollution caused by a large amount of sulfur oxides in ship exhaust gas, some international and regional organizations have enacted legislation to limit the emission of sulfur dioxide from ships. Since reducing the sulfur content of low fuel oil is the most direct and effective emission reduction measur...
