Description
Technical field
The present invention relates to a kind of tunnel cave, be meant a kind of expanded letter energy-conserving and environment-protective tunnel cave that pottery burns till that is used for especially.
Background technology
Got into since 21 century, world's art ceramics product is accelerated to the paces of top grade development greatly, and owing to the raising of global energy anxiety and environmental consciousness, ceramic product also tends to the low energy consumption development simultaneously.Burning till is the critical process in the Production of Ceramics, and it is related to the aspects such as quality, class, yield rate and production cost of ceramic product, and the energy major part of consumption is used to burn till and baking operation, accounts for more than 80% of total energy consumption.At present, the energy utilization rate of China's ceramic industry is very big with external gap, and the energy utilization rate of developed country is generally up to more than 50%, and China only reaches about 28～35%; In Japan, the thermal efficiency that pottery adopts flaming to have saggar to burn till reaches 4.8～8.8%, and China is merely 2～8%.
Existing kiln main fuel is a 0# diesel oil, and its discharged flue gas still has certain pollution to surrounding environment, and kiln adopts shuttle kiln and car tunnel kiln more, and such kiln energy consumption is generally higher.The diesel oil ignition point is high, and low-temperature burning is prone to heavy carbon, makes porcelain produce defectives such as sootiness, pin hole; Sulfur dioxide in the diesel combustion product can influence the glossiness of Ceramic glaze.The fuel oil kiln generally is contained in ceramic body in the saggar, and muffle burns till, first heating saggar in the sintering process, and heating ceramic base substrate again, and the saggar amount of stored heat is big, has greatly wasted the energy.Car tunnel kiln is taken away great amount of heat energy because of kiln car accumulation of heat and heat radiation in sintering process, make the Beijing enamel energy consumption high.Therefore, the fuel oil tunnel cave can't satisfy the needs that high-grade art ceramics develops and builds a resource-conserving society, preserves the ecological environment.
In addition, along with the variation of fuel structure and the update of refractory material, the structure of industrial ceramics kiln and performance have all had very big improvement, but aspect Energy Saving Control, still relatively lag behind, and particularly core heat energy equipment and technology lags behind.The key of industrial ceramics saving energy in kiln is the linear scale control technology that solves fuel and air, makes its abundant completing combustion, will guarantee the linear controllability of air-fuel ratio in the continuous burning process simultaneously.Domestic industry ceramic kiln combustion control technology only rests on single-phase control fuel at present, and combustion air can't be implemented in the synchronous proportional adjusting of fuel, causes the waste of fuel.
At last, ceramic body is to get into tunnel cave at normal temperatures, and to differ nothing many for the also many and room temperature of the temperature of ceramic when the tunnel klining becomes the back kiln discharge, and temperature can reach 1200～1300 ℃ in the tunnel cave, and the temperature difference of the interior diverse location of tunnel cave can be bigger.Existing tunnel cave is begun all to be provided with firing equipment to the stage of burning till by kiln hood, so that ceramic body progressively heats up up to burning till, and very big of the fuel consumption in this stage; Tunnel cave promptly began progressively to lower the temperature after process heated up and burns till the stage; Ceramic and tunnel cave are interior along with decrease of temperature; Heat loses in dissipation, and existing tunnel cave capacity usage ratio is comparatively low, and the furnace air circulation is inhomogeneous; The temperature difference at the diverse location in same stage is bigger, and the product defect rate is higher.
