Technical Field

The invention belongs to the technical field of thermal power plants, and particularly relates to a plasma pyrolysis gasification system of a thermal power plant.

Background

In recent years, in the three northeast regions of China, the capacity of the power market is rich, peak-adjustable power supplies such as a gas turbine and pumped storage are scarce, the contradiction between the peak adjustment of a power grid and the flexibility of a thermal power generating unit is prominent, the capacity of the power grid for absorbing new energy such as wind power, photoelectricity, hydropower and nuclear power is insufficient, and the phenomena of wind abandoning, light abandoning, water abandoning and nuclear abandoning are serious. The cogeneration unit operates in a mode of 'fixing the power by heat', and the peak regulation capacity is only about 10%. The peak shaving difficulty has become the most prominent problem in the operation of the power grid. At present, the flexible peak regulation and reconstruction of domestic thermal power aims at a heat supply unit in winter, and how to regulate the peak in summer is a difficult problem in the presence of a plurality of thermal power plants. In order to meet the peak regulation requirement of a power grid and the survival requirement of a power plant in intense competition, deep peak regulation especially in non-heating seasons is imperative all the year.

Meanwhile, some solid wastes are treated and utilized, partial residues always exist and are difficult to recycle, and the residues can be enriched with a large amount of toxic and harmful components; there are also solid wastes, which are currently not available, which remain in the environment for a long time and are a potential source of pollution. In order to control its environmental pollution, it must be finally disposed of to the maximum extent possible from the biosphere. At present, domestic and foreign municipal solid waste treatment methods mainly comprise recycling, sanitary landfill, incineration, composting and the like. The domestic municipal solid waste treatment adopts a few technologies, including recycling, incineration technology and sanitary landfill. The main reason is that the industry eliminates the backward capacity, and more enterprises are willing to increase the investment of technical equipment and production sites due to the requirements of safety and environmental protection, and a series of technologies such as a plasma gasification furnace, a plasma gasification melting furnace, a plasma pyrolysis furnace and the like are applied. However, no matter how to promote the operation of the plasma gasification melting furnace or pyrolysis furnace technology and automatic equipment, the power consumption for treating the solid waste by the plasma gasification melting furnace or pyrolysis furnace cannot be changed to about 700-900 kWh in a short time, so that the power consumption cost and the treatment cost become the key for determining the solid waste treatment cost and the enterprise competitiveness.

How to reduce the solid waste treatment cost and reduce the energy consumption needs further research and solution by technicians in the field.
