The alcohol wastewater discharged in the production of alcohol is a high concentration of organic wastewater, COD content is very high, if handled improperly impact on the environment caused by a lot of pollution. There are a variety of processing alcohol waste, but most of them are not completely solve the problem of environmental pollution, the alcohol waste analysis, boiler incineration the alcohol waste of organic pollutants completely burned . To do so, not only to achieve zero emissions of waste water and alcohol waste burned as fuel, energy savings, while the ash can be used as potash, alcohol production enterprises will have a better economic and social environmental benefits. Research and development fueled with alcohol waste boiler Unlike the boiler, starting from the characteristics of the alcohol waste, considering its viscosity, concentration of into the furnace, the heat transfer characteristics of the combustion characteristics and produce smoke. Thermodynamic calculation of boiler design, layout, obtained by the heat balance analysis and reasonable heating surface of the boiler thermal efficiency of 77.2%. Boiler thermodynamic calculation special composition of the flue gas heat exchanger between the heating surface is different from coal-fired boilers, there are differences in the various coefficient selection with conventional boilers. Conventional boiler combustion devices are analyzed and discussed the proposed the alcohol waste incineration introduced into the fluidized bed from top to bottom spray fluidized bed black liquor. Black liquor gun each layout surrounded by water wall in the furnace wall, the alcohol waste is injected into the furnace by the gun down, rapid warm-up encounter high temperature flue gas and fluidized bed material in the course of the whereabouts of the black liquor evaporation, combustion and burning embers. At the bottom of the furnace, the line arrangement of many small hood to form a fluidized bed. When the boiler operation, high-speed primary air is ejected from the hood of the orifice, the bed material in the blowing on a fluidized bed, a fluidized state, to make the furnace into a material within the loop. Fluidized bed material is a relatively large regenerator, it has played a key role in alcohol wastewater into the furnace heating. Combustion mode with extended the alcohol waste residence time in the furnace, and accelerated heat, evaporation and combustion speed is conducive to the alcohol waste burning ember, to improve the thermal efficiency of the boiler. The discussions also focused on the boiler design the layout and the role of secondary air. In the next three on the gun burner arranged secondary air, the ratio of 1:1:1, and the secondary air furnace gas to mix was stirred, so that the furnace flue gas to create a vortex, extending the suspended fly ash and fly ash the stroke of the combustible material in the furnace, the fly ash and fly ash combustibles further reduced. Its rational use can make the reduced amount of fly ash, the fly ash combustibles reduced. In addition to the supply part of the suspended combustible air conducive mentioning
