The novel kiln comprises a kiln, a preheating section, a high temperature section and a heat dissipation section are sequentially arranged in the kiln. An insulation separator is arranged in the kiln, the kiln is separated into a lower main kiln inner cavity and an upper drying kiln inner cavity by the insulation separator. The main kiln inner cavity and the drying kiln inner cavity are respectively provided with a roll type transmission device, stainless steel plate which is used for separating smoke and transferring heat is arranged at the lower side of the roll type transmission device in the preheating section of the man kiln inner cavity, a gas burner is arranged in the high temperature section of the main kiln inner cavity. A gas inlet of a spray purifying column is communicated with the main kiln inner cavity, and a gas outlet thereof is communicated with a chimney. The novel kiln has the characteristics that the structural design is reasonable, the comprehensive energy consumption is low, and the dust emission accords with the requirement of environmental protection.
Description
Technical field
The utility model relates to the Industrial Stoves that are used for the firing ceramics product, particularly is that fuel is fired product, utilized the radiating segment waste heat to come the roller kilns of dry products with the combustion gas.
Background technology
Burn in the roller kilns field at coal, the discharging along with environmental requirement minimizing flue dust cuts down the consumption of energy, and makes full use of waste heat in the hope of reducing production costs, and improves output, quality.For example, old-fashioned coal burns roller kilns, fires product with coal-fired the heat transfer every cigarette by carborundum plate.This furnace operation difficulty is big, and temperature is wayward, and coal, deashing, slagging-off, labour intensity workload are big, and temperature is low, and the product strength that burns out is poor, water absorption rate is big, and gives off the volume of smoke contaminated air from kiln.Reach more than 20% in the high temperature radiation loss with the carborundum plate heat transfer, preheating section front end furnace flue temperature is at 500～600 ℃, but transfer heat to the upper strata temperature by carborundum plate and have only 50～80 degree, heat loss is up to 80%, have only 8～10 months the service life of carborundum plate, changing carborundum plate must stop production at every turn, and the repair time wants a wheat harvesting period just can resume production.Existing carborundum plate market price is per ton more than 9000 yuan, and coal burns the roller kilns radiating segment 700 degree, and waste heat does not use.Labor strength is big, temperature is wayward, burn out poor product quality, kiln weak point service time, recondition expense are big so old-fashioned coal burning roller kilns exist, energy consumption is consumed the shortcoming big, that soot emissions are big.
The utility model content
The purpose of this utility model provides that a kind of reasonable in design, energy consumption are low, the environmental protection and energy saving novel kiln of soot emissions compliance with environmental protection requirements.
This novel purpose is achieved in that a kind of environmental protection and energy saving novel kiln, comprise kiln, preheating section, high temperature section and radiating segment are arranged in the stove in turn, thermal-insulation baffle plate is arranged in the described kiln, it is divided into bottom master's kiln inner chamber and top dry kiln inner chamber, be respectively arranged with the roll-type conveyer in main kiln inner chamber and the dry kiln inner chamber, the preheating section internal roller type conveyer below of main kiln inner chamber is provided with every the cigarette heat transfer uses corrosion resistant plate, is provided with fuel burner nozzle in the high temperature section of main kiln inner chamber; The air inlet of spraying purifying column is communicated with main kiln inner chamber, and its gas outlet is communicated with chimney.
Compared with prior art, this novel beneficial effect is:
1, makes full use of main kiln radiating segment waste heat dry products
On main kiln radiating segment upper strata dry kiln is set, has reduced occupation area of equipment, main kiln radiating segment adopts the high temperature stainless steel plate to conduct heat, 500～700 ℃ of waste heats of radiating segment have been made full use of, improve main kiln product cooling rate, thereby can improve output, reduced the fuel consumption level.
2, adopt the high temperature stainless steel plate to conduct heat
Conduct heat with the high temperature stainless steel plate, make that heat transfer is faster, heat loss is littler, improved temperature, the high temperature stainless steel plate can use 3～5 years, had reduced recondition expense and time, thereby had improved service life, had reduced production cost, had improved product quality.
3, high temperature section is directly fired product without smoke baffle plate
High temperature section adopts bright burning, has improved the energy consumption utilization rate, and transmission device upper and lower, both sides are provided with burner, can regulate the control temperature better, make temperature higher, more stable, improve product strength, can fire blue or green semicircular tile, fill up the blank that domestic employing roller kilns are fired blue or green semicircular tile.
4, adopt spraying purifying column smoke abatement
Do fuel with coal gas, with spraying purifying column (being connected) smoke abatement with chimney or air exhauster, the water that purified can be recycled, can utilize waste water to make its more environmental protection (can load material in the purifying column again, the spray regime of water from the top down, flue gas from bottom to top, dust in flue gas is adsorbed with water takes, thereby reaches discharge standard).
