Blended With Alcohol Waste Boiler Design

The alcohol that produces the alcohol rear row discards the organic waste water that the liquid belongs to a high density, the COD content is very high, if not be handled properly and will bring very great pollution to environment. There are many ways to deal with them at present,but these way can not deal with them completely.In this article,we analyse the alcohol waste liquid and give a way to settle this problem by burning them in boiler Do like this, carry out to discard a liquid not only of zero exhaust, and the alcohol discard liquid as fuel to burn down, economizing energy, but the ash residue can be a potassium fatty, this produces a business enterprise to the alcohol and will produce the better economic performance and social milieu performance.The research development burning the alcohol discards uses the boiler that the alcohol discards a liquid, differing from general boiler, the characteristic that needs to discard a liquid from the alcohol set out, considering it to glue a degree,go into a stove a density and burning characteristic and producing smoke to annoy of transmit heat characteristic. We calculate the thermal efficiency is 77.2% by thermal calculate thermal balance analysis .. and the reasonable disposal of accepting heat parts. At the thermodynamic energy calculation of the boiler is medium, because the composition of the smoke spirit is special, it and each be subjected to hot noodles of change heat to also differ from the general brunning coal boiler, the selection and the normal regulations boiler of various coefficient also have difference.This text carried on an analytical discussion to the burnable equipments of the normal regulations boiler, putting forward burning alcohol to discard the liquid demand to lead to go in to flow to turn a bed, being flowing to turn a black liquid inside the bed to spray to pour from top to bottom. The alcohol discards was sprayed in to hearth from the adjutages which are laid at the water-cooling walls.In the course of descent, the waste liquid is heated>vaporized^burnning and burn out finally,, At hearth bottom, the agreeable row decoration contain many small breeze hats, the formation flows to turn a bed. When running the boiler ,the first wind with high speed Sprayed from the map,and blow the fuel to form liquid state, and form a cyculation in the hearth.Flowing to turn a bed to anticipate is a hotter than bigger saving body, it had in the Tightness the heating that goes into a heat of alcohol to discard a liquid more decisive function. The coeporation of two ways not only delay the stay time of alcohol discards but also accelerate the calefaction> evaporation and burning, in favor of burning alcohol discards completely and hightenning the heat efficiency of boiler.That boiler design returns the decoration and the function that the point discussed two breezes. We laid three tiers of the second wind on fires,their ratio are 1:1:1.The second wind mixes the gas in hearth and let the gas form burble , delay journey of flying ash and combustible in the hearth,let the combustible burning completelyo Its reasonable usage can make to fly the amount of ash decrease, making to fly a combustible thing of ash to lower, the heat efficiencyN reduce the temperature of somke which is ejected out of boiler> in favor of economizing energy and protecting envionment.The alcohol discarded a liquid to flow to turn the bed boiler to still consider to circulate factor well during the period of design. We discuss controlling the temprature of CFB, using the second wind rightly, controlling the pressure disparity of fuel and hearth, granularity of fuel on the bed, the time of waste liquid being spray into the hearth etc.Control that boiler bed in the movement about 850 °C , since can satisfy the combustion of the boiler, again easy to the realization takes off sulphur effectively in the stove. The pressure disparity is the key factor , it decide to course the bedding feul or not. In the course of circulation, the pressure of hearth exit should be 0 to 200 Mpa.This pressure disparity shoud be considered naturals Another the alcohol discard devotion time of the liquid is the key that that boiler can circulate normally, be boiler to throw in the coal consecution to circulate after lighting the fire 2-4 can immediately spray to discard a liquid into the jot after hours, discard first single of the liquid air gun devotion, treat to circulate a normal empress to increase gradually, keep to all devotions.The alcohol discards a liquid to flow to turn the bed boiler an application in the alcohol the production the business enterprise, can make the alcohol discard a liquid to change to discard for the treasure, not only economize energy but also reducing alcohol to discard a liquid's pollution for environment. The tempreture in boiler is about 850 °C ,at this tempreture sulphurscan be burned completely and be able to protect environment. The alcohol discards the hurl that the liquid flows to turn the bed boiler to use, can make comprehensive exploitation of the ash residue, because the boiler implies an or so potassium chemical element of 20% in the burnable output ash residue, on being compound to admix to anticipate fattily, moreover can lift Be a chemical engineering raw material purely.So this produces a business enterprise to thealcohol and will produce the better economic performance and social milieu performance.
