Description
Technical field
The utility model relates to tunnel kiln, is specially a kind of ceramic Natural Gas Fueled Tunnel Kiln stove of producing.
Background technology
Natural Gas Fueled Tunnel Kiln stove is to produce ceramic visual plant.The kiln car that ceramic body is housed enters in turn from kiln entrance, and by the sintering process in tunnel kiln, what the kiln car that exports out from kiln carried is exactly ceramic product.Existing tunnel kiln, due to the defect of furnace binding, is difficult to ensure the particularly product quality of high-grade bone china of pottery, and meanwhile, a large amount of high-temperature gases that produce in body of heater are discharged in vain, and energy consumption is higher.
Summary of the invention
The utility model solves the ceramic Natural Gas Fueled Tunnel Kiln stove of existing production and is difficult to ensure ceramic product quality and the higher problem of energy consumption, and a kind of ceramic Natural Gas Fueled Tunnel Kiln stove of producing is provided.This tunnel kiln reasonable in design, novelty, be applicable to particularly high-grade bone china of production high-quality pottery, and energy consumption is lower.
The utility model is to adopt following technical scheme to realize: produce ceramic Natural Gas Fueled Tunnel Kiln stove, comprise body of heater, body of heater is made up of preheating section, the section of burning till, quench zone, control cooling section and final cooling section successively; The section of the burning till sidewall of body of heater is evenly equipped with the burner noz(zle) of fuel gas inlet and combustion air entrance (being also burner); The quench zone sidewall of body of heater is evenly equipped with the quench air input pipe inserting in body of heater, and each quench air input pipe is connected with chilling blower fan by the road; The top of the final cooling section of body of heater is provided with the cooling-air input pipe inserting in body of heater and the waste heat air output pipe communicating with the final cooling section inner chamber of body of heater, cooling-air input pipe is connected with cooling blower, waste heat air output pipe is provided with waste heat fan and combustion fan, and the output of combustion fan passes into the preheating section inner chamber of body of heater by the road; The combustion air entrance of burner noz(zle) is connected with the output pipeline of combustion fan by the road; The fuel gas inlet of burner noz(zle) is connected with combustion gas input house steward by the road.
Body of heater is divided into preheating section, the section of burning till, quench zone, control cooling section and final cooling section by the utility model, is conducive to improve the quality of ceramic product.Preheating zone: base substrate in drying the burning stage, is got rid of remaining moisture content in base substrate at first, and chemical change does not occur base substrate, and volume contraction only occurs, the physical changes such as intensity, porosity increase.Along with kiln car advances, kiln temperature constantly raises, and base substrate generation series of physical, chemical reaction, mainly contain: the oxidation of carbon element, organic matter, sulfide; The crystallization water decomposes, sulfate, carbonate decomposition, transformation of crystal etc.Clinkering zone: be oxidized, decomposition reaction, base substrate forms liquid phase and solid phase fusion, and forms new crystalline phase, and now base substrate shrinks, and density increases, strength increase, the porosity reduces, and goods are sintering at high temperature, forms tight entirety.Quench zone: base substrate Ci district is in retrospective state, the now cooling liquid phase crystallization that not only can prevent rapidly, crystal is grown up and is reduced iron oxidation, improve the mechanical strength of base substrate, and goods can not ftracture.Control cooling section: this district's base substrate liquid phase starts to solidify, and transformation of crystal causes volume contraction, and tension appears in base substrate inside, and hardness intensity increases to maximum, now needs to control cooling velocity at 70 DEG C/h, to prevent fried porcelain.Final cooling section: product rapidly cooling (speed can reach 100 DEG C/h) to suitable temperature so that kiln discharge.
When kiln work, the kiln car that is mounted with ceramic body enters from the preheating section of body of heater, and kiln body burner noz(zle) sprays into combustion gas and combustion air burning to the body of heater section of burning till and forms high temperature.Chilling blower fan blasts a large amount of high velocity airs through quench air input pipe to body of heater quench zone, to realize the chilling of product in this section.Cooling blower blasts cooling-air through cooling-air input pipe to the final cooling section of body of heater, finally cooling with before realizing product and coming out of the stove.Waste heat fan is by the high-temperature gas suction waste heat air output pipe in body of heater, high-temperature gas is sent into the preheating before body of heater preheating section is fired ceramic body through the supercharging of combustion fan in waste heat air output pipe, simultaneously as combustion air in burner noz(zle) feeds back to body of heater (cold combustion air can reduce the calorific value of combustion gas), like this, by the cycling and reutilization of the high-temperature gas to body of heater, effectively improve the utilization rate of energy, reduced the energy consumption of kiln.
Natural Gas Fueled Tunnel Kiln stove described in the utility model, furnace binding is reasonable in design, novel, is applicable to the ceramic of production high-quality, is especially applicable to production high-grade bone china.By the cycling and reutilization of the high-temperature gas to body of heater, effectively improve the utilization rate of energy, reduce the energy consumption of kiln.
