The novel energy-saving kiln comprises a kiln body, a combustion device and a fan device. The kiln body is composed of a preheating section, a firing section and a cooling section. The preheating section, the firing section and the cooling section are respectively provided with an internal kiln channel, the preheating section accounts for 20%-40% of the total length of the kiln body, the firing section accounts for 30%-40% of the total length of the kiln body, and the cooling section accounts for 20%-40% of the total length of the kiln body. The technical detects that a traditional kiln device is large in occupied area and low in thermal efficiency are overcome.
Description
Technical field
The present invention relates to a kind of Industrial Stoves, especially a kind of pottery, refractory material kiln.
Background technology
Tunnel cave, roller kilns are continous way production kilns that a kind of air-flow is bottom horizontal flow sheet, are widely used in the sintering process of all kinds of potteries, refractory material.The particularly tunnel cave taking liquefied petroleum gas as fuel, roller kilns, due to its product, to burn till yield rate high, and steady quality, more obtains general applying.
Existing ceramic kiln has the defect of following two aspects:
1. drying shed area is large especially, and kiln length is long, takies a large amount of land resource, and cost of investment is high.Sintering procedure is wasted a large amount of energy.According to statistics, energy consumption cost accounts for the 30-40% of Production of Ceramics cost, and wherein the energy consumption of firing process accounts for again the 70-80% that produces total energy consumption;
2. the firing process of existing pottery, refractory material is: pottery, refractory material base substrate are first cured and carry out high temperature after dry again and burn till; Pottery, refractory material base substrate to cure that dry and high temperature burns till be in drying shed and burning kiln, to carry out respectively, drying shed and burning kiln dispose respectively warm-air supply and gas burning system; The problem existing is: the energy consumption of pottery, refractory material drying shed and burning kiln is higher, and the fume afterheat of pottery, refractory material burning kiln is underutilized.
In sum, energy-conservation is the key issue that pottery, refractory material reduce production costs in producing all the time.Though existing pottery, tunnel kiln of fire resisting material, roller kilns have been taked a lot of measures on energy-conservation, but still it is inhomogeneous to exist kiln body clinkering zone section temperature, cause goods stress larger, easily cause and ftracture and extended firing time, and fuel burner nozzle when work combustion air did not reach optimum state and affects some areas for improvement such as efficiency of combustion with mixing of fuel.
Summary of the invention
Object of the present invention, be to provide a kind ofly integrate that microwave and hot blast composite heating are dry, the Novel energy-saving kiln of kiln tail UTILIZATION OF VESIDUAL HEAT IN, oxygen-enriched combusting.
Technical scheme of the present invention is achieved like this:
A kind ofly integrate that microwave and hot blast composite heating are dry, the Novel energy-saving kiln of kiln tail UTILIZATION OF VESIDUAL HEAT IN, oxygen-enriched combusting, comprise kiln body, burner, blower fan apparatus, described kiln body is made up of preheating section, the section of burning till, cooling section, and preheating zone, clinkering zone and salband are equipped with kiln internal channel.
Preferably, wherein preheating section accounts for the 20-40% of kiln body total length, and the section of burning till accounts for the 30-40% of kiln body total length, and cooling section accounts for the 20-40% of kiln body total length.
Preferably, described clinkering zone is vertically installed with twice firebreak at two ends, high-temperature region, and top, high-temperature region and other warm area top are separated.
Preferably, one end of preheating section is provided with charging aperture, is intervally distributed with multiple being arranged into a rectangular array and big or small identical rectangular-shaped waveguide entrance on preheating section.Air-heater is also set on preheating section, and air-heater is arranged on the outside of bottom half, and the hot-wind inlet of air-heater is arranged on the bottom of preheating section, is also provided with the hot blast plate with hot blast hole.
Preferably, cold air inlet and hot-blast outlet are set on cooling section, described cold air inlet is connected airduct with hot-blast outlet, and cold air inlet connects natural wind blower fan by airduct, and hot-blast outlet is communicated with kiln combustion fan and preheating section by airduct.
Preferably, combustion system comprises oxygen rich fuel gas burner, gas pipeline, oxygen-enriched combustion-supporting air duct.
The present invention is dried burning kiln with existing gas hot-air pottery and is compared, and has the following advantages:
1. the fume afterheat water conservancy diversion of realizing burning kiln arrives in the burner hearth of drying kiln or is used as combustion air, and the fume afterheat of burning kiln is fully used, and the comprehensive energy consumption of burning kiln and dry kiln is reduced; Solve existing gas hot-air pottery, refractory material and dried the problem that the existing burning kiln fume afterheat of burning kiln is underutilized and baking room burning kiln energy consumption is high.
2. the microwave hot air recombination energy pottery, the refractory material series of products drying and sintering machine that the present invention relates to, floor space is little, has dwindled 30% through the preheating section length of overtesting kiln body, burns till segment length and has dwindled 20%; A large amount of occupation of land of the prior art, the thermal efficiency is low, product drying is inadequate technical problem are solved; Greatly save land resource; Absorb traditional drying sintering process equipment homogeneous heating and the pure microwave drying sintering thermal efficiency is high, the fireballing advantage of drying and sintering, the problems such as traditional drying sintering process occupation area of equipment is large, the thermal efficiency is low, environment is severe, and pure microwave drying sintering is inhomogeneous are overcome.
3. furnace construction improves, and has thoroughly solved the problem ceramic, refractory material is fired yielding cracking, and product percent of pass is high, because preheating section, the section of burning till, cooling section shorten, saves the energy and has improved production efficiency simultaneously, has reduced toxic emission.
