Problems solved by technology

[0008] The disadvantages of methods 1 and 2 are that maritime law enforcement personnel are required to board the ship for sampling inspection when the ship is in port or at anchor, which has low detection efficiency, affects the normal operation of the ship, and cannot cover all ships in the carbon emission control area
Method 3 is affected by factors such as strong winds. The measurement accuracy of the drone equipped with telemetry sensing equipment is relatively large. In addition, the drone stays in the air for a short time and the remote control distance is limited. It can only be used for spot checks and cannot cover all carbon emission control areas. ship
Because so far there is no effective means to detect the exhaust of all ships in the ship air pollution control area, resulting in most ships not using low-sulfur fuel oil as required and not being monitored effectively in a timely manner, which affects the implementation of the ship air pollution control area plan Effect

Embodiment 1

[0028] Such as figure 1 As shown, an online monitoring system for ship exhaust gas includes exhaust gas analysis equipment 100 installed on the ship and exhaust gas monitoring equipment 200 installed on the shore.

[0029] The exhaust gas analysis equipment 100 includes an exhaust gas collection analyzer 101 , a light transmitter 102 , a light receiver 103 , a temperature compensation device 104 and a first communication device 111 , and the first communication device 111 includes a Beidou terminal control unit 105 and a Beidou antenna 106 .

[0030] The light transmitter 102 and the light receiver 103 are respectively fixed on both sides of the inner cavity of the ship's chimney 107 . The light emitter is an infrared emitter, and the light receiver is an infrared receiver; or, the light emitter is an ultraviolet emitter, and the light receiver is an ultraviolet receiver.

[0031] The exhaust gas collection and analysis instrument 101 includes a central processing unit 108 , ...

Embodiment 2

[0051] Compared with Embodiment 1, this embodiment differs only in that the data communication between the first communication device and the second communication device adopts 3G communication, or 4G communication, or 5G communication, or VSAT satellite communication.

[0052] When the first communication device and the second communication device adopt 3G communication, 4G communication or 5G communication, the first communication device contains a 3G communication module, 4G communication module or 5G communication module respectively, and the second communication device contains a corresponding 3G communication module. module, 4G communication module or 5G communication module.

[0053] Within the coverage of the mobile base station, 3G communication, 4G communication or 5G communication is used, which has the advantages of convenient communication, fast signal transmission and low communication cost.

[0054] When the first communication device and the second communicatio...

Abstract

The invention discloses a ship tail gas online monitoring system which comprises tail gas analysis equipment arranged on a ship and tail gas monitoring equipment arranged on the bank. The tail gas analysis equipment comprises a tail gas collection analysis instrument, a light emitter, a light receiver, a temperature compensation device and a first communication device; the tail gas monitoring equipment comprises an information display and alarm device, an electronic nautical chart system and a second communication device; the electronic nautical chart system and the second communication deviceare respectively connected to the information display and alarm device; and the first communication device and the second communication device carry out data communication in a wireless communicationmode. According to the invention, ship tail gas monitoring efficiency and monitoring accuracy can be improved, and the ship tail gas online monitoring system is greatly convenient for the maritime law enforcement department to carry out online monitoring on emission of ship tail gas in a ship pollution emission control region and fulfills the aims of effective monitoring, real-time monitoring andtotal monitoring.

Description

technical field [0001] The invention relates to an on-line monitoring system for ship tail gas. Background technique [0002] In December 2015, the Ministry of Transport issued the "Implementation Plan for Ship Emission Control Areas in the Pearl River Delta, Yangtze River Delta, and Bohai Rim (Beijing-Tianjin-Hebei) Waters". Oxide and particulate matter emissions, improve the ambient air quality of my country's coastal and riverside areas, especially port cities, and lay the foundation for comprehensive control of ship air pollution. [0003] In this plan, ship emission control areas in the Pearl River Delta, Yangtze River Delta, and Bohai Rim (Beijing-Tianjin-Hebei) waters are established, and the core port areas in the emission control areas are determined. During berthing in the port area (except for one hour after berthing and one hour before departure), fuel oil with a sulfur content of ≤0.5% m / m should be used; since January 1, 2018, ships in the emission control area ...
