Abstract

The invention relates to a coal gasification ash content treatment device and a method. The method comprises the steps of: under the condition of having no need of reducing pressure, enabling gasified black water to directly flow in an ash separator, filtering and separating ash from the gasified black water through the ash separator to obtain ash water with an ash content of below 100ppm, cooling and pumping the ash water to a gasified device for recycling. The coal gasification ash content treatment device and method have the advantages of replacing the recycling process of flash evaporation, sedimentation, vacuum filtering, pressurization and the like in the traditional gasified ash water treatment processes, and directly removing ash under the condition of not reducing the pressure of the black water. The process flow is simple, and the investment, occupied space and energy consumption can be greatly reduced.

Description

[technical field]

[0001] The invention relates to a coal gasification ash processing device and method, in particular to an ash processing device and method for a coal gasification water quenching process. [Background technique]

[0002] As one of the three major petrochemical energy sources in my country, coal is mainly used in important fields such as civil fuel, power generation, chemical industry, and industrial fuel. "Rich in coal, short of oil and low in gas" is the basic characteristic of my country's energy resources. Coal, as an important fuel and chemical raw material, plays an extremely important role in the development of my country's national economy. It is imperative to develop oil and natural gas substitute products that use coal as raw materials. At the same time, the development of modern new coal chemical industry is an effective means for the integration and upgrading of my country's coal resource real estate industry structure.
