Abstract
The invention discloses a solid waste gasification system and a gasification method thereof. At present, solid waste disposal is mainly based on incineration, which is likely to cause secondary environmental pollution. The air distribution mechanism is arranged at the bottom of the furnace body of the present invention; the primary air inlet of the air distribution mechanism communicates with the gasification fan through the one-way mixer, and the secondary air inlet communicates with the inner cavity of the furnace body through the annular air duct, and also communicates with the outlet of the one-way mixer. The tuyere; the mixed steam inlet of the one-way mixer is connected with the high-temperature steam outlet; the furnace body is divided into an upper space layer, a drying chamber, a dry distillation chamber, a lower space layer, a reduction chamber, an oxidation chamber and ash chamber; the drying chamber layout and the high-temperature steam inlet Connected dry steam nozzles, retort steam nozzles connected to the high-temperature steam inlet in the retort chamber; high-temperature steam coils are arranged in the dry chamber and retort chamber, connected to the high-temperature steam inlet and high-temperature steam outlet; Arrange the reducing gas outlet in layers. The invention continuously transforms solid waste into combustible gas and high-temperature sintered and solidified slag to achieve harmlessness.
Description
technical field [0001] The invention relates to a solid waste gasification system and a gasification method thereof, in particular to a solid waste gasification system and a gasification method based on enhanced reaction of high-temperature superheated steam. Background technique [0002] Solid waste, referred to as solid waste, refers to the solid and semi-solid waste produced by human beings in production, consumption, life and other activities. In layman's terms, it is "garbage", mainly including solid particles, garbage, slag, sludge , discarded products, damaged containers, defective products, animal carcasses, spoiled food, human and animal feces, etc. In some countries, high-concentration liquids such as waste acid, waste alkali, waste oil, and waste organic solvents are also classified as solid waste. [0003] Usually, according to the source of solid waste, it can be divided into urban domestic solid waste, industrial solid waste and agricultural waste; according t...
