Abstract

The invention provides a biomass coal water slurry prepared by combining phenolic wastewater and biomass charcoal, and a production method and a production system for the biomass coal water slurry, belonging to the technical field of coal water slurry fuel. The biomass coal water slurry adopts the biomass charcoal, coal and the phenolic wastewater as slurrying raw materials, has the advantages ofbiomass fuel, and realizes direct recycling of the phenolic wastewater in the coal chemical industry at the same time; meanwhile, the biomass coal water slurry utilizes the phenolic wastewater to replace water as a pulping raw material, makes up for the defect of low calorific value of the biomass charcoal, increases the calorific value of fuel, and has important social benefits and economic benefits. The biomass coal water slurry provided by the invention comprises the following components in parts by weight: 20-60 parts of pulverized coal, 10-50 parts of biomass charcoal powder, 30-50 partsof the phenolic wastewater, 0.3-0.7 part of a dispersant and 0.3-0.7 part of a stabilizing agent.

Description

technical field [0001] The invention belongs to the technical field of coal-water slurry fuel, and in particular relates to a biomass coal-water slurry jointly prepared by phenol-containing wastewater and biomass charcoal, a production method and a production system thereof. Background technique [0002] The distribution of fossil energy in my country is characterized by rich coal, poor oil, and little gas. Coal accounts for more than 60% of my country's primary energy structure. Coal chemical industry is an effective way to realize efficient utilization of coal resources. However, coal chemical industry is a highly polluting industry. During the conversion and utilization of coal, a large amount of coal chemical wastewater will be generated, which contains a large amount of phenols, ammonia nitrogen, tar, cyanide, polycyclic hydrocarbons, oxygen-containing polycyclic and heterocyclic compounds. A variety of toxic and harmful substances that are difficult to degrade will cau...
