Problems solved by technology

However, different from vehicle exhaust monitoring, ship exhaust monitoring has the problems of difficult boarding and chimney, especially in open waters such as big rivers and seas
At present, it can only be monitored when the ship is berthing at the port, and the efficiency is very low

Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the following embodiments in no way limit the present invention.

[0028] First of all, the monitoring ship is modified and instrumented before sailing: a corresponding monitoring system is installed on the deck of a maritime patrol ship. The monitoring system includes a retractable mast fixed on the deck and a continuous air quality monitoring system also installed on the deck.

[0029] Among them, the telescopic mast fixed on the deck is an automatic telescopic rod with the model number TX12-320-3800-32000 purchased from Nanjing Xuedian Technology Co., Ltd.; the automatic telescopic rod takes the cylinder as the core, which is equivalent to a multi-section cylinder The stretching and shrinking action of the telescopic rod is realized by inflating and deflated into the cylinder. The total height after full stretching is 32 meters, and the to...

Abstract

The invention discloses a method for performing mobile monitoring on tail gas of a ship. The method comprises the following steps: enabling a monitoring ship to pass through a tail gas band of a monitored ship by adjusting the shipping direction of the monitoring ship relative to the monitored ship, sampling tail gas discharged by the monitored ship by an air quality continuous monitoring system arranged on the monitoring ship, acquiring the CO2 concentration and the polluted gas X concentration of the tail gas, calculating the polluted gas X discharge factor in the discharged tail gas of the monitored ship based on the discharge factor of oil consumption, comparing the polluted gas X discharge factor with the conventional regulated ship tail gas discharge standard, and determining whether the suspicion that discharge of the tail gas of the monitored ship exceeds standard exists or not. The method for performing mobile monitoring on the tail gas of the ship is suitable for big river open water, an efficient method is provided for monitoring the tail gas of the ship in the ship discharge control area in China, the check pertinence of anchored ships is improved, the efficiency is improved, and waste of manpower and financial resources caused by blind inspection is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of ship tail gas monitoring, in particular to a method for monitoring ship tail gas movement. Background technique [0002] In recent years, more and more monitoring results have shown that ship exhaust contributes a lot to air pollution in coastal cities, even the main contributor. However, different from vehicle exhaust monitoring, ship exhaust monitoring has the problem of difficult boarding and chimney, especially in open waters such as rivers and seas. At present, it is only possible to board the ship for monitoring when the ship is berthing, and the efficiency is very low. How to monitor ship exhaust without boarding in open waters is a necessary technical condition for the supervision of ship exhaust in the ship emission control area. Contents of the invention [0003] The purpose of the present invention is to provide a ship exhaust movement monitoring method that can monitor the ship exhaust wit...
