Description

A ship solid waste plasma gasification power generation system and its treatment method

technical field

The invention relates to the field of power generation, in particular to a ship solid waste plasma gasification power generation system and a processing method thereof.

Background technique

At present, with the increasing maritime trade, maritime traffic and maritime tourism, the impact of ships on the environment, society and economy is becoming more and more significant. Among them, the impact of ships on the environment includes the treatment and disposal of solid waste generated by ships. For large and medium-sized ships, a large amount of solid waste will be generated during its operation. If you choose to store the solid waste, it will take up a large space, pollute the cabin environment, and produce harmful gases, which will affect the health of the crew. ; If you choose to discharge solid waste into the ocean, it will lead to eutrophication of part of the seawater and produce harmful gases, which will threaten marine life and its habitat, and will also cause navigation safety hazards and other issues, which will seriously affect the marine environment and maritime traffic. Therefore, there is a need for harmless treatment of solid waste.

At present, the main treatment methods for solid waste from ships include direct discharge after crushing, reduced volume storage and transfer to shore for treatment, and incineration. Among them, although direct discharge after crushing reduces the harm of solid waste to the environment, it will still damage the marine environment. Therefore, this treatment method is subject to increasingly strict marine protection laws and regulations, and the types that can be treated are limited and the treatment conditions are strict. The treatment method of volume reduction storage and transfer to shore can reduce the space occupied by the solid waste of the ship to a certain extent. However, even if the storage time is limited, the solid waste stored on the ship will cause the deterioration of the air quality inside the ship and affect the health of personnel. Health, on the other hand, requires the support of port receiving facilities, which increases the cost of equipment, and if the transshipment time is too long, it is easy to cause secondary pollution. The effect of the incineration treatment method is remarkable, but the current ship incinerator is huge and heavy, which requires a lot of space on the ship, and the incinerator takes a long time to start and stop, and the incineration process will also produce fly ash and dioxins. Substances need to be processed twice, and the processing cost is relatively high.

In recent years, there has also been a method of using plasma technology to treat ship solid waste to recycle resources. Among them, plasma gasification technology can completely convert organic matter into synthesis gas (mainly CO and H2) due to its high temperature and high heat density, while inorganic matter is melted into inert glass. In the patent "Thermal Plasma Incineration Ship Garbage Device" (CN101737785A), a thermal plasma incineration ship garbage device is proposed. The efficiency is higher and more energy-saving; the second combustion chamber also uses plasma treatment to prevent new pollution. However, the system does not pre-treat ship solid waste, which will lead to insufficient incineration, and the slag contains more organic substances. At the same time, the system does not consider the issue of resource utilization. To sum up, the current treatment methods of various types of ship solid waste basically follow the principle of harmless treatment, but do not take into account the treatment efficiency and the energy recovery and utilization of solid waste. Therefore, there is a need for an efficient ship solid waste treatment method that can recover and utilize the energy in the solid waste.
