Abstract
The present invention provides a low heat value organic waste liquid burner for treating organic waste liquid with a low heat value. The present invention is characterized in that the lower part of a burner body of the burner is provided with a boiling bed, and the upper part of the burner body is provided with a waste liquid concentrator; waste liquid concentrating grooves are formed at the top and the circumference between the inner burner wall and the outer burner wall of the waste liquid concentrator, the bottoms of the waste liquid concentrating grooves of the circumference are respectively provided with a discharge opening which is connected with a concentrated liquid feeding opening through an output pipeline, and the concentrated liquid feeding opening is arranged between the boiling bed and a boiling segment; a smoke channel outlet of a burner chamber of the burner is provided with a waste liquid preheater and an air preheater. According to the characteristics of the organic waste liquid with a low heat value, the organic waste liquid is first put into the waste liquid concentrator to carry out high-concentration concentration; subsequently, the organic waste liquid is thrown in the boiling bed so as to be burned so that the waste liquid is completely burned; in this way, the utilization ratio of energy sources is raised, energy needing to be complemented is reduced. Besides, the present invention has the advantages of light weight of the burner body, low cost and easy remove of pollutants.
Description
One, technical field
The present invention relates to a kind of is the burner of purpose to handle the low heat value organic liquid waste.
Two, background technology
Organic liquid waste is owing to its high-moisture, low heat value, and directly burning is caught fire and kept burning and all compare difficulty.So-called low heat value is meant that low heat valve is lower than 1000kcal/kg, is meant that generally caloric value is the calorific value of 500～600kcal/kg.Usually produce a large amount of low heat value organic liquid wastes in the industrial production, as produce the alcohol effluent that 1 ton of alcohol will produce 15 tons, if these waste liquids directly discharge, will serious environment pollution, destroy the ecological balance.The method that firing method is handled organic liquid waste is relatively more commonly used at present and reasonable method, multifuel combustion in bagasse or the coal is mixed with waste liquid by the enterprise that has, and the shortcoming of this method is that power consumption is big and the liquid waste processing amount is limited, and boiler is tied ash easily, influence the long-term safety operation of boiler, reduce the efficient of boiler.
Three, summary of the invention
Task of the present invention is to propose a kind of low-heat-value organic waste-liquor burner that can make the abundant completing combustion of low heat value organic liquid waste, to avoid the existing existing shortcoming of firing method technology of handling organic liquid waste.
The present invention concentrates by earlier organic liquid waste being carried out high concentration according to the characteristics of low heat value organic liquid waste, drops into the technical conceive that burns in the burner again, forms the technical scheme of burner structure of the present invention.The concrete structure of this low-heat-value organic waste-liquor burner is: the body of heater bottom of burner is an ebullated bed, and top is the waste liquid inspissator; Said waste liquid inspissator has outer furnace wall and internal protecting wall, the top of its outer furnace wall is provided with waste liquid charging aperture and steam outlet, form the waste liquid thickener at top and perisporium between its internal protecting wall and the outer furnace wall, the top of its top waste liquid thickener has overfall to lead to the waste liquid thickener of perisporium, the bottom of its perisporium waste liquid thickener has discharging opening to be connected to the concentrate charging aperture of the boiling section that is positioned at ebullated bed by the concentrate output channel, also be provided with the lime-ash overfall and auxiliary fuel adds inlet at the boiling section of ebullated bed, wherein the lime-ash overfall is positioned at the top that said concentrate charging aperture and auxiliary fuel add inlet; Be provided with the flue of discharging flue gas on the burner hearth sidewall top of waste liquid inspissator, be provided with waste liquid preheater and air preheater at the flue outlet place, utilize high-temperature flue gas respectively the organic liquid waste of the waste liquid charging aperture of input waste liquid inspissator and the air that feeds the ebullated bed bottom to be carried out preheating.
Ebullated bed in the burner of the present invention need keep higher ignition temperature, and its furnace wall should adopt refractory material to be built into; The effect of said waste liquid inspissator is to utilize the heat of burner hearth that waste liquid heating is concentrated, thus the waste liquid inspissator internal protecting wall should adopt the good thin-walled material of heat conduction to make, be generally metal material, be preferably stainless steel material or alloy aluminum material.
Be simplified structure, said concentrate charging aperture and auxiliary fuel add inlet can be designed to same mouthful.
The technique effect of this low-heat-value organic waste-liquor burner is: one, the high-temperature flue gas that utilizes ebullated bed to produce by the waste liquid inspissator comes preheating and concentrated low heat value organic liquid waste, makes nonflammable low heat value organic liquid waste be condensed into the high heating value organic liquid waste; Two, utilize that ebullated bed is big as thermal capacity, the steady combustion burning things which may cause a fire disaster of high temperature, burn in ebullated bed through the high heating value organic liquid waste after concentrating, can make the incineration of liquor of input complete, can improve rate of energy, reducing needs additional energy, and the organic waste residues that can also avoid not firing is attached on the furnace wall.The actual major part that accounts for body of heater of waste liquid inspissator that the present invention is designed, this part body of heater can adopt the lighter thin-wall construction of weight, and whole body of heater weight is alleviated greatly, saves the ground expense, reduces the cost of stove.
