Monitoring system for modular ship exhaust gas desulfurization device

Abstract

The invention discloses a monitoring system for a marine exhaust gas modular desulfurization device. The monitoring system comprises a main control cabinet, a pump monitoring module, a washing tower monitoring module, an alkali supply monitoring module, a water treatment monitoring module and an HMI control module, and TCP / IP protocol communication transmission is performed between the main control cabinet and the monitoring signals of the pump monitoring module, the washing tower monitoring module, the alkali supply monitoring module and the water treatment monitoring module; the HMI controlmodule is in signal connection with the main control cabinet signal through bus communication; and the main control cabinet transmits action instruction signals to the pump monitoring module, the washing tower monitoring module, the alkali supply monitoring module and the water treatment monitoring module to realize modular matching and logic control in order to realize the execution and monitoring in an open, closed or hybrid desulfurization mode. The modular design and installation of a monitoring network structure for the ship exhaust gas desulfurization device and the system are realized by bus signal transmission and modular monitoring in order to achieve rapid design of the device and the efficient operation of integration, installation and debugging of the system.

Description

technical field [0001] The invention belongs to the technical field of ship high-end equipment, and in particular relates to a monitoring system of a ship tail gas modular desulfurization device. Background technique [0002] Ship exhaust emission pollution is one of the main sources of air pollution and marine environmental pollution. The emissions of carbon dioxide, nitrogen oxides and sulfur oxides can directly affect the global climate and the acidification of the marine environment. The release of other liquids, gases and particles are harmful to human health. also pose a serious threat. In 2010, the amendments to the International Maritime Organization (IMO) International Convention for the Prevention of Pollution from Ships (MARPOL) came into force, and on January 1, 2020, sulfur emissions in global seas shall not exceed 0.5%. The installation of EGCS (Exhaust Gas Cleaning System) is the most effective and economical way to reduce emissions. At present, about 30,000 ...

AI Technical Summary

Problems solved by technology

A large number of temperature, pressure, and flow analog signals are connected to the control cabinet, and the amount of electrical construction is large. At the same time, the wiring distance of the ship is long, the operating environment is uncertain, and the electromagnetic interference is serious.
