Abstract
An objective of the invention is to provide an energy-saving tunnel kiln with high energy use ratio and long service life. The energy-saving tunnel kiln comprises a kiln body. A plurality of heat-resistant infrared radiation plates are detachably mounted on the inner wall of a kiln chamber of the kiln body. One side, facing the inner portion of the kiln chamber, of each heat-resistant infrared radiation plate is provided with an infrared radiation layer. One side, facing the kiln chamber wall, of each heat-resistant infrared radiation plate is provided with a thermal insulation layer. The infrared radiation layers are made of corundum-mullite plates or mullite plates. The thermal insulation layers are ceramic fiber blankets.

Description
Technical field
The present invention relates to a kind of energy-saving tunnel kiln.
Background technology
China's Industrial Stoves and Industrial Boiler are the main bodys of energy resource consumption, and the Industrial Stoves ubiquity thermal efficiency is low, the phenomenon that energy waste is larger.Low for the ubiquitous effective utilization rate of energy of Industrial Stoves, the problem that energy waste is larger, general taked Main Energy-saving Measures is both at home and abroad: (1) adopts the light weight type insulation material of high insulating effect as far as possible; (2) adopt far infrared energy-saving spray painting technology; (3) flue gas heat recovery; (4) black body radiation element power-saving technology.
Traditional approach is to adopt less light material and the insulation material of thermal capacitance to build kiln, to reduce accumulation of heat and radiation loss.This power-economizing method, just heat " is blocked up " in kiln thorax, do not need the available heat of the product of sintering to absorb, do not change " diffuse reflection " state of heat ray, do not solve the problem whether heat ray puts in place, so need the available heat of product of sintering still very low.People by heat Balance Calculation or test, find that heat accumulation of kiln and radiation loss are up to 60%～70%, and need the available heat only 25%～30% of the product of sintering.
The thermal efficiency of heat storing type energy-saving tunnel cave obtains raising by a relatively large margin; The application of infrared radiation coating subsequently, the available heat that has solved the product that needs sintering on the basis of high thermal effect absorbs problem, has further improved the thermal efficiency.
In industry kiln kiln thorax, conduct heat and have: the convection heat transfer' heat-transfer by convection of the product radiation of Fire Radiation, burning, the radiation of the furnace wall surface of solids and furnace gas radiation and furnace gas.In simple terms, participate in the 3 kinds of basic objects that have of the interior heat exchanging process of kiln: furnace gas, Yao Bi, heating and calcining thing.At 800 ℃, be that heat transfer between kiln gas and heating object mainly relies on convection heat transfer' heat-transfer by convection below; Between 800 ℃～1000 ℃, be to rely on convection current and radiation, when temperature, the heat conduction between kiln gas and heating object is main during higher than 1000 ℃ relies on far infrared radiation heat exchange simultaneously, and the heat 90% that heating object absorbs realizes by radiation heat transfer.Most of industry kiln kiln thorax is interior by refractory brick, castable refractory, and fire-resistant light insulating brick or ceramic fibre are built by laying bricks or stones.These refractory materials have fire resistance, under high temperature, intensity is high, the characteristics such as stability height can meet kiln needs, but the far infrared transmissivity of these refractory materials generally in 0.35 left and right (as at 1100 ℃: chamotte brick: 0.35～0.65, mullite 0.4, aluminium oxide 0.18～0.52, refractory fibre 0.35), and the emissivity of coatings capable of preventing from far infrared radiation is 0.85～0.95.Infrared radiation heat transfer is exactly the radianting capacity heating object that utilizes infrared ray uniqueness, object is heated, at a certain temperature, heating object gives off the infrared waves with certain penetration capacity, make heating object generation molecular oscillation, produce energy level transition, the infrared ray of the certain wave band of radiation, thus produce heat.Its feature one is heat absorption object thermally equivalent, the 2nd, and heat from inside to outside, thereby reduced the heat time, improve energy utilization rate.
The basic weakness of far infrared coating technology is that coating is easily aging, and continuous efflorescence is in actual use dropped or by air-flow erosion, thermal infrared emissivity progressively decays, and loses infra red radiation function, and thermal effect is passed decline in time.
