In liquor-making enterprises, there are two processes, one is fermentation and the other is distillation, which must be produced by steam. However, at present, many domestic liquor brewing processes still use traditional workshop production, lack of continuity and compactness between the various processes. In addition, the primitive process equipment has also led to the low overall production efficiency of the industry, large energy consumption of grain raw materials, water and electricity, and serious pollutant emissions. The traditional workshop-style production mode has seriously restricted the future of the industry. Among them, the waste gas from traditional coal-fired boilers in liquor enterprises contains more pollutants. Although various provinces and municipalities have issued different policies on the elimination of small boilers burning coal, heavy oil and wood, the direction is the same: low consumption and low emission is the basic, and the ultimate goal is to achieve the ecological production of wine enterprises.
