Abstract
The invention relates to a furnace for carbonizing and incinerating high-concentration salty organic waste liquid. The furnace comprises a furnace body consisting of a combustion chamber 1 and a combustion chamber 2, wherein the combustion chamber 1 is provided with a waste water spray gun; the combustion chamber 2 is provided with a combustion gun; a flue gas outlet is formed on the top of the combustion chamber 2; and a molten salt pond is arranged below the combustion chamber 1 and is provided with a gas lean-oxygen combustion gun. The equipment can completely melt and recycle salt in waste water in the combustion chamber 1, the whole process flow cannot be blocked and can be normally and persistently operated, and the equipment has a simple structure, long service life and a good treatment effect.
Description
Technical field
The present invention relates to a kind of saliferous organic liquid waste carbonization incinerator, especially a kind of incinerator that carries out the carbonization burning disposal for high concentration saliferous organic liquid waste.
Background technology
At present, the high concentration brine waste generally be by incinerator burn, evaporation process, owing to can not separate water out with salt, the salt in the waste water all enters into the dual firing chamber of incinerator along with flue gas, when dual firing chamber reaches 1100 ℃, salt becomes molten condition, sticking stifled everywhere system equipment need not be how long, and a whole set of technology just can't normally be moved, and salt concentration is more in the waste gas, and dust does not reach emission request yet.
Chinese patent application 200520076529.8 discloses " a kind of saliferous organic waste liquid burning system ", comprise incinerator, deduster, waste heat recovery apparatus, No. one time the incinerator furnace roof is equipped with the waste liquid import, the outlet at bottom pipeline connects cyclone dust collectors, house-bag duster for high temperature is connected in gas outlet, cyclone dust collectors top, the top exit of house-bag duster for high temperature connects the secondary incinerator, and the gas outlet pipeline of secondary incinerator connects waste heat recovery apparatus.This system once burns the back with the saliferous organic liquid waste to remove most of salt powder with cyclone dust collectors, remove remaining salt powder with house-bag duster for high temperature again, the flue gas of salt concentration is not used the incinerator second-time burning again, remove the salt powder with cyclone dust collectors and house-bag duster for high temperature, this device generally is applicable to the lower waste water of salt content (about 3-6%), if handle the waste water of higher salt content, particularly near the waste water of saliferous about 20%, owing to when once burning, effectively do not dispose the salt in the organic liquid waste, salt through high temperature incineration can be adsorbed onto cyclone dust collectors and house-bag duster for high temperature surface, it is caused corrosion, in addition, because of the concentration height, it is unsatisfactory to remove effect, and remaining salt can stop up latter equipment along with flue gas, cause system's operation chaotic, and the salt in the gas can cause secondary pollution again along with the washing of road, back, and soot emissions do not reach standard.
Summary of the invention
The present invention is just in order to overcome above-mentioned deficiency, a kind of simple in structure, high concentration saliferous organic liquid waste carbonization incinerator that can carry out burning disposal and salt is reclaimed out high concentration saliferous organic liquid waste is provided, it can effectively isolate the salt in the high concentration saliferous organic liquid waste fast in burning process, treatment effect is better, long service life.Main innovation is below a combustion chamber of incinerator molten salt pool to be set, coal gas combustion with meagre oxygen rifle is set, the high-temperature gas combination of the waste water of atomizing and combustion with meagre oxygen, the organic matter in the carbonization waste water on the molten salt pool, simultaneously with the salt in the waste water and moisture from coming out, salt drops in molten salt pool.
Specifically implement like this: high concentration saliferous organic liquid waste carbonization incinerator, comprising that the body of heater of being made up of combustion chamber and a dual firing chamber, fires on the chamber is equipped with the waste water spray gun, be equipped with the burning rifle in the dual firing chamber, the dual firing chamber top is provided with exhanst gas outlet, it is characterized in that below, a combustion chamber is provided with molten salt pool, is equipped with coal gas combustion with meagre oxygen rifle on the molten salt pool.
One combustion chamber utilizes coal gas combustion with meagre oxygen rifle, and the salt carbonization in the waste water is come out, and realizes separating of salt and water; Salt drops in the molten salt pool, and the heat energy by molten salt pool dissolves into salt liquid, adds salt outlet on molten salt pool, allows the salt of fusion flow out automatically, and the Quench by air makes it into crystalline solid, can regeneration reclaim; Water becomes steam and enters dual firing chamber, continues to reach 800 ~ 1100 ℃ by the burning gun burner, and is thoroughly that it is burning out, carries out road, back exhaust-gas treatment again.Because salt concentration not in the waste gas, so can fusion not stop up, waste gas is through the high-temperature cyclone dust extractor of postorder, remove the dust in the waste gas, then enter waste heat boiler and waste heat hot-water boiler, can attached producing steam and hot water, reduce processing cost, accomplish that really refuse becomes precious, the waste gas after the cooling is removed the moisture content in the waste gas by scrubbing tower washing, desulfurizing tower desulfurization, steam-water separator, passes through the chimney qualified discharge through air-introduced machine.
The present invention is designed to the concavity shape that subtended angle is the obtuse angle with the nozzle surface of waste water spray gun, subtended angle is 120 °-150 ° preferably, change nozzle surface into concavity shape by the plane body of routine, can control the diffusance of waste water atomizing, allow the time lengthening of high-temperature gas combination of waste water and combustion with meagre oxygen, a thorough organic matter in the carbonization waste water, the 2nd, with the salt in the waste water and moisture from coming out, the salt molten salt pool fusion of dropping is come out, and water becomes steam and enters dual firing chamber.
The present invention is with all fusion recovery in a combustion chamber of the salt in the waste water, and a whole set of technological process can not stopped up, and can normally move lastingly, and device structure is simple, long service life, and treatment effect is good.
Description of drawings
Fig. 1 is a structural representation of the present invention.
