Problems solved by technology
At that time, biomass power generation will also produce a large amount of residual ash. The plant ash after biomass burning has many problems in the traditional treatment methods, such as being used as fertilizer and cannot be mixed with "ammonia nitrogen" fertilizers. Soil compaction and other issues
Simple landfill and construction use will bring hidden dangers of groundwater pollution due to rainwater leaching

Embodiment 1
[0022] A kind of technology that utilizes plant ash to prepare potassium acetate deicing agent, this utilizes plant ash to prepare the technique concrete steps of potassium acetate deicing agent as follows:
[0023] S1: The acquisition of wastewater in the production of cellulosic ethanol. A large amount of wastewater containing acetic acid, furfural and 5-hydroxymethylfurfural will be produced in the production of cellulosic ethanol, and these wastewaters will be collected for later use;
[0024] S2: Mixing plant ash, mixing the plant ash with the waste water obtained in step S1, mixing the mixed waste water with the plant ash and pouring it into the agitator for full stirring, so that the plant ash and the waste water are fully mixed, and after the mixing is sufficient, mix the plant ash with the waste water The waste water mixture is filtered to remove the insoluble matter;
[0025] S3: the evaporation process of the vacuum rotary evaporator, adding the mixed solution of wa...

The invention discloses a process for preparing potassium acetate deicing agent using plant ash. The specific steps of the method for flattening and deep plowing and applying desulfurized gypsum to improve saline-alkali land are as follows: S1: acquisition of waste water in cellulose ethanol production, S2: mixing of plant ash, S3: Evaporation process in vacuum rotary evaporator, S4: ethanol rinse. Through stirring, filtering, evaporating, rinsing and other processes, the present invention uses biomass ethanol wastewater and plant ash to prepare a sodium acetate deicing agent that can melt snow efficiently and environmentally friendly while realizing intelligence. Compared with the traditional treatment method of plant ash, It not only reduces environmental pollution, but also has economic value.
Description
technical field [0001] The invention relates to the technical field of chemical engineering, in particular to a process for preparing potassium acetate deicing agent from plant ash. Background technique [0002] According to the "Twelfth Five-Year Key Special Plan for the Development of Biomass Energy Science and Technology" proposed by the Ministry of Science and Technology, biomass energy will be developed in an orderly manner, and biomass power generation will be developed with agricultural and forestry residues. At that time, biomass power generation will also produce a large amount of residual ash. The plant ash after biomass burning has many problems in the traditional treatment methods, such as being used as fertilizer and cannot be mixed with "ammonia nitrogen" fertilizers. Soil compaction etc. Simple landfill and construction use will bring hidden dangers of groundwater pollution due to rainwater leaching. [0003] With the continuous exploration and development o...
