Description
Technical field
The utility model relates to lime calcining field, especially a kind of multilayer natural gas active lime kiln.
Background technique
Under the main trend that all trades and professions require energy-saving, emission-reducing, environment friendly, current limekiln (including layer rock layers coal, flint are mixed
Burning and rotary kiln and introduction kiln type) there is different degrees of defect.As coal stone multifuel combustion kiln cannot guarantee burning and life do not occur
It burns, certified product rate is very low, and consumes energy not environmentally, is forbidden by various regions government, and the investment of import kiln type is excessive, also has calcination process
Unreasonable place is consumed energy higher.
China Patent Publication No. CN101195520A, publication date on June 11st, 2008, the entitled vertical continuous forging of invention
Burning lime kiln, including columnar kiln body, kiln body is disposed with from top to bottom closes wind feeding device, position at the top of kiln body
In the distribution device on kiln body inner cavity top, the preheating zone below distribution device, the calcination area below preheating zone, it is located at
It is calcined the cooling zone below area, the continuous discharging device below the discharge port of cooling zone, the top of kiln body is arranged equipped with kiln gas
Outlet pipe is equipped with the hot wind air-out passage for being axially arranged and extending to preheating zone along kiln body, hot wind outlet air in the inner space of kiln body
The barrel in channel is equipped with several discharge air ports.The intracorporal flue gas of kiln is directly discharged out of kiln gas discharge pipe, by purified treatment
After be discharged into atmosphere, the waste heat of flue gas is not utilized, and flue gas, which is expelled directly out, wastes these waste heats.Combustion air is going out
Material mouth position is sent into, and combustion air cooling itself is also preheated while the lime of cooling zone, the combustion air after preheating
Calcination area is reached for combustion-supporting, but the temperature after the combustion air preheating after these preheatings is lower, still to absorb when combustion-supporting
The more heat transfer in limekiln calcination area, this just wastes the more energy in calcination area, increases the consumption of fuel, also increase
Cost.
