Process for preparing chemical raw material gas or fuel gas by taking vinasse as main raw material and utilizing moving bed pure oxygen continuous gasification furnace

Abstract

The invention relates to a process for preparing chemical raw material gas or fuel gas by taking vinasse as a main raw material and utilizing a moving bed pure oxygen continuous gasification furnace, and belongs to the fields of environmental protection, biochemical engineering and gasification. The process comprises a vinasse storage and pretreatment method, an additive preparation method, a pulverized coal processing method, a stirring retting method, a rod making method, a drying method and a gasification method. Water gas can be used as raw material gas for chemical production after being subjected to dust removal, purification and the like, and is used for producing various chemical products. As the water gas has a higher heat value, the water gas can also be used as industrial or civil gas. Practice proves that a large amount of vinasse which is difficult to dispose in a winery can be turned into wealth, the residual value of the vinasse is improved, better economic benefits and environmental protection benefits can be obtained, and the method has a wide application prospect.

Description

technical field [0001] The invention relates to a process for producing chemical raw material gas or fuel gas by using distiller's grains as the main raw material and using a moving bed pure oxygen continuous gasification furnace, which belongs to the fields of environmental protection, biochemical industry and gasification. Background technique [0002] With the rapid development of my country's social economy, people's living standards have been greatly improved, and the number and number of wine consumers are increasing year by year. The economic benefits of various wineries increase with the increase in wine demand. Liquor is brewed from grain crops such as sorghum, barley, and rice. The remaining residue after brewing is distiller's grains, which increase significantly with the increase of wine production. [0003] Distiller's grains, also known as red grains, distiller's grains, dregs, etc. If the distiller's grains after brewing cannot be unused or disposed of in tim...
