Abstract

The invention relates to the technical field of coal gasification, and provides a coal water slurry gasification system and a coal water slurry additive recovery method. The system comprises a pulpingand conveying unit, an additive separation unit, a water removal unit, a gasification furnace and a collection tank; the pulping and conveying unit comprises a coal mill, a coal slurry tank and a coal slurry feeding pump which are connected in sequence; the coal slurry feeding pump is connected with the additive separation unit, the additive separation unit is connected with the water removal unit, the water removal unit is provided with a water outlet and a coal outlet, the water outlet is connected with the collection tank, and the coal outlet is connected with the gasification furnace; theadditive separation unit and the water removal unit are arranged between the pulping and conveying unit and the gasification furnace; the additive separation unit is adopted to destroy the adsorptionconnection relationship between the additive and the coal particles, so that the additive is dissolved in water, then the water in which the additive is dissolved is separated from the coal particlesthrough the water removal unit, the additive is recycled, and the coal water slurry gasification cost is saved.

Description

technical field [0001] The invention belongs to the technical field of coal gasification, and in particular relates to a coal water slurry gasification system and a method for recovering coal water slurry additives. Background technique [0002] At present, coal water slurry is mainly used in coal water slurry gasification technology. Coal water slurry is composed of coal powder with a certain particle size, water and additives in a certain proportion. It has good stability, fluidity and other properties, and is safe to store. , convenient transportation and measurement, and can be transported over long distances. [0003] Since the coal-water slurry is required to have good stability and fluidity during storage and transportation, additives need to be added. However, in the process of coal gasification, the additives and the coal-water slurry are directly burned after being fed into the gasification furnace, resulting in a lot of waste. [0004] Therefore, how to recycle ...
