Description
Technical field
The invention relates to a kind of glass kiln, particularly about a kind of glass kiln that adopts emulsified coke slurry burner.
Background technology
Usually, the comparatively energy of cleaning that the glass kiln adopts at present mainly is oil, Sweet natural gas or coal gas etc., and still, this rises the fuel cost of glass kiln significantly, has had a strong impact on the existence of using and making the enterprise of glass kiln.
For this reason, those skilled in the art is developing the new available energy hardy.Emulsified coke slurry fuel cheap, high effect cleaning becomes the new lover in this area gradually.In the glass kiln, adopt the emulsified coke slurry fuel can the reasonable use natural resources, can reduce the fuel cost of glass kiln again, so the emulsified coke slurry combustion technology is all being widelyd popularize in countries in the world.
Yet in emulsified coke slurry when burning, exist the difficulty of catching fire, easily coking, flame to disperse, be difficult to the problem of after-flame, industry continuous exploitation can the active combustion emulsified coke slurry Thermal Equipment.A kind of water coke slurry buring technology that is disclosed for CN02135439.1 number as Chinese patent, it comprises twice wind tangent air inlet on settling chamber and the wall thereof, tangential twice wind speed is 25～40m/s, end in settling chamber is equipped with the wind turbulent burner one time, the swirl strength of a wind is greater than 3.0, the burnt slurry of water atomizing lance is settled in the turbulent burner central zone, be atomized into 60～100 μ m granularities by its burnt slurry of water that will enter settling chamber, the other end of settling chamber is the opening port that connects Industrial Stoves or glass kiln, after the pre-burning room temp will reach 950～1000 ℃ of temperature at least, guarantee the burning of the burnt slurry of water stable ignition.The burnt slurry of a kind of water cyclone burner that disclosed for CN03113078.X number of Chinese patent and for example, formed by spray gun, combustion chamber, tangential wind inlet, whirlwind tube combustion chamber is cylindric, the burnt slurry of water spray gun is located at an end of whirlwind tube combustion chamber, once tangential wind inlet, twice tangential wind inlet are set in sequence on the wall of the burnt whirlwind tube combustion chamber of starching the spray gun downstream of water, and the other end in whirlwind tube combustion chamber is provided with whirlwind tube combustor exit.But above-mentioned two water coke slurry combustion apparatus that patent disclosed and method exist defective, at first, only adopt the burnt slurry of water spray gun, reach enough intensity of combustion, the feed rate that must add the burnt slurry of big flood, that is, it is far that the burnt slurry of water particle will spray, and combustion powered that forms like this is elongated, inhomogeneous, not full, thereby can not make the burnt slurry of water particle obtain burning effectively fully, in case the burnt slurry of water particle burning is insufficient, it leaves after the combustion chamber, along with decrease of temperature, it will coking on furnace wall or hot blast tube wall, after coking acquires a certain degree, will reduce the heat transfer efficiency of equipment, serious also will cause security incident; Secondly, only adopt the burnt slurry of water spray gun, must restart igniting in case this spray gun is flame-out, what influence was produced normally carries out; Also have, only adopt the burnt slurry of water spray gun, be difficult to effectively the fully atomizing of the burnt slurry of water can not be atomized effectively, just can not guarantee that the burnt slurry of water particle is sufficient to contact with air and burn that efficiency of combustion is not high; And, only adopt the burnt slurry of water spray gun, and other ignition device is not set, have no idea in principle the burnt slurry of water is directly lighted, even in fact the method that adopts first fuel oil to change the burnt slurry of water spray gun again can not light the burnt slurry of water; At last, a wind of above-mentioned two patents is not distinguished with the air that tangential elegance is used, if the air of a wind does not heat, then can cause burning inviolent, if tangential wind does not adopt freezing air, then just can not reach effective reduction combustion chamber inner wall temperature and avoid the effect of coking.
In addition, emulsified coke slurry nitrogen content height will produce a large amount of oxynitride after the burning, and such as nitrogen protoxide, nitrogen peroxide etc., these nitrogen oxide compound are discharged in the air will cause topsoil.Such as, nitrogen protoxide is a no color or smell gas, it generally can not produce harmful effect to human body, but when it is transformed into nitrogen peroxide, just has corrodibility and physiological stimulation effect; When nitrogen peroxide content when 100ppm is above, several minutes just can cause humans and animals desperately, inhaled concentration is that 5ppm (is 9.4mg/m
2) nitrogen peroxide, several minutes just can cause respiratory system imbalance; And oxynitride will cause photo-chemical smog, such as, as HC and NO
xAfter in atmospheric environment, being subjected to strong solar ultraviolet irradiation, produce a kind of photochemical reaction of complexity, generate a kind of new pollutent-photo-chemical smog.The photo-chemical smog that December nineteen fifty-two, London took place, in 4 days death toll throughout the year the same period many approximately at most dead more than 4000,45 years old, be about at ordinary times 3 times, be about at ordinary times 2 times below 1 years old.In the week that incident takes place, be respectively 9.3 times, 2.4 times, 5.5 times and 2.8 times of incident similar death toll the last week because of bronchitis, coronary heart disease, pulmonary tuberculosis and the person's of having a weak heart death.Therefore, strict restriction has all been made to the quantity discharged of oxynitride in countries in the world.So,, must adopt various measures to reduce the generation of oxynitride in the emulsified coke slurry combustion processes at the high characteristics of emulsified coke slurry nitrogen content.The method and apparatus that can be used to reduce the generation of oxynitride at present mainly is at burning of coal.As a kind of powdered coal burner that Chinese patent is disclosed for No. 97199607, it has a transitional region that plays shock absorption between main region and auxiliary area.Transitional region is by providing restricted recirculation zone between main region and auxiliary area, thereby improves the control near mixing the burner and flame stability.These restricted recirculation zone send back near the burner outlet an oxygen deprivation pyrolytic decomposition zone being reduced into dinitrogen with the oxynitride of emitting, thereby reduce the loss of discharging and uncombusted fuel.It can be seen from the above, and at first, this burner structure only is suitable for the burning of fine coal and is not suitable for the burning of emulsified coke slurry; Secondly, this burner is oxynitride to be reduced into dinitrogen, its structure and complex process by special oxygen deprivation pyrolytic decomposition zone.
Also have, contain a large amount of lime-ash in the emulsified coke slurry gas fume after burning,, will sneak in the material, influence the quality of glass, therefore must manage before entering the glass kiln, most of lime-ash to be removed in case these lime-ash enter the glass kiln.But, also do not have a kind of device preferably effectively the dust in the emulsified coke slurry flue gas to be removed at present.The invention personnel if make combustion chamber temperature reach grey melting point, just can make overwhelming majority ash discharge with the form of liquid through several times experiment discovery.But also there is not a kind of combustion chamber temperature that can make effectively to reach the emulsified coke slurry burner of grey melting point at present.Some technician of this area is used for Thermal Equipment with the slag tap technology, a kind of reverse combustion type coal water slurry slag tap roasting kiln that is disclosed for No. 02240518 as Chinese patent, mainly by the body of heater shell, upper combustion chamber, the taper reducing, lower combustion chamber, air outlet, heat collector, the collection slag bath is formed, it is characterized in that: the body of heater shell is a metal shell, its inboard wall of burner hearth carries out moulding with refractory materials, and top is upper combustion chamber, and structural shape is the tubular construction than minor diameter, top is airtight on it, and the bottom of upper combustion chamber extends for the taper reducing; One side of taper reducing is an air outlet, and it is lower combustion chamber down, and the structural shape of lower combustion chamber is the diameter tubular construction bigger slightly than upper combustion chamber diameter, and its underpart is a convergent cone; The extendible portion of air outlet is a heat collector, structural shape is a round shape bivalve layer structure, inwall applies with certain thickness refractory materials, in the middle of it is hot-air channel, the circular channel is arranged in the bivalve, on the end of heat collector burner blower is installed, heat collector and, secondary combustion air house steward is connected with three combustion air house stewards; Uniform setting has upwards and the coal water slurry spout of oblique angle on the furnace wall, middle part of upper combustion chamber, once combustion-supporting airduct and coal water slurry spout and one, secondary combustion air house steward is connected, make progress and the combustion-supporting airduct of the secondary of identical oblique angle being equipped with up and down of coal water slurry spout, and with one, secondary combustion air house steward is connected, and is equipped with three combustion-supporting airducts of oblique angle on the furnace wall, middle part of lower combustion chamber, and is connected with three combustion air house stewards.As can be seen from the above analysis, at first, this reverse combustion type coal water slurry slag tap roasting kiln is not suitable for the burning of emulsified coke slurry; Secondly, the chamber temperature of this reverse combustion type coal water slurry slag tap roasting kiln does not also reach the cindery ash fusion point of emulsified coke slurry, the emulsified coke slurry lime-ash can't be liquefied; At last, the chamber structure complexity of this reverse combustion type coal water slurry slag tap roasting kiln, manufacturing cost is higher.
In addition, for make system continuously, normal operation, that must in time change the burner bottom connects the slag device, and, also contain a large amount of waste heats that can be utilized in the liquid slag, if directly the liquid slag inflow is connect the slag device, will cause the waste of the energy.
At last, because the Heating temperature of glass will reach more than 1600 ℃, and the emulsified coke slurry calorific value is lower, can not meet the demands, so must select for use the high-temperature heat accumulation technology to be cooperated.
Therefore, but provide high-temperature heat accumulation high, that can realize slag tap and the glass kiln that can effectively reduce the employing emulsified coke slurry burner that enters amount of nitrogen oxides in the atmospheric tail gas of a kind of efficiency of combustion to become the problem that industry need solve.
