Technical field
The utility model relates generally to lime production field, particularly relates to a kind of lime stone kiln.
Background technology
Current due to industrialized development, the industry of Iron And Steel Industry, calcium carbide, aluminum oxide industry etc. are all lime consumption rich anies influential family, and country is for the requirement of energy-saving and emission-reduction now, to the requirement of environmental protection of enterprise index; On the other hand, the thermal content of the waste gas of the preheating zone of existing kiln is more much bigger than the absorbent amount of Wingdale, due to such situation, traditional limestone kiln will consume more heat and carry out warm-up combustion-supporting air, the gas simultaneously discharged is containing a large amount of recuperable heat, and this situation causes high calorie consumption; The lower fuel supply of kiln causes overheated in addition, thus causes the burning of lime and the refractory life of lime is shorter.
Utility model content
Technical problem to be solved in the utility model is: the Novel lime kiln providing a kind of energy-conserving and environment-protective, utilizes waste heat, reduces kiln bottom superheating phenomenon.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of lime stone kiln, it comprises the first opening for feed, scavenging air valve, fuel port, burning shaft furnace, cross aisle, cooling room, non-burning stove, waste gas outlet, described first opening for feed is connected with burning shaft furnace, described scavenging air valve is connected with burning shaft furnace, described burning shaft furnace is connected with cross aisle one end, described cross aisle one end is connected with non-burning stove, described burning shaft furnace is connected by cross aisle with non-burning stove, described non-burning stove is connected with waste gas outlet, described waste gas outlet is in non-burning furnace roof portion.
Further, described non-burning furnace roof portion is provided with the second opening for feed.
Further, described lime stone kiln is provided with the first cooling room, the second cooling room, and described cooling room is connected with burning shaft furnace, and another cooling room described is connected with non-burning stove.
Further, described first cooling room, the second cooling room, be respectively equipped with the first intake valve, the second intake valve.
Further, described cooling room is respectively equipped with the first cooling tube, the second cooling tube, the 3rd cooling tube, the 4th cooling tube, and described 3rd cooling tube, the 4th cooling tube are provided with 2 holes with it.
Further, described lime stone kiln also comprises combustion air.
Further, described non-burning stove passes into combustion-supporting gas, and its waste gas body generated enters burning shaft furnace by cross aisle.
Have employed technique scheme, beneficial effect of the present utility model is: make the high-temperature gas in burning shaft furnace enter heat conduction in non-burning stove by burning shaft furnace with being connected by cross aisle between non-burning stove, reaches the object of effectively reduction energy consumption.

Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Be illustrated in figure 1 a kind of lime stone kiln of the utility model, it comprises the first material mouth 1, scavenging air valve 2, fuel port 3, burning shaft furnace 4, first cooling room 5, second cooling room 8, 3rd cooling room 15, 4th cooling room 16, first intake valve 6, second intake valve 7, non-burning stove 9, waste gas outlet 10, second material mouth 11, cross aisle 12, first refrigerator pipe 13, second refrigerator pipe 14, 3rd refrigerator pipe 17, 4th refrigerator pipe 18, described first opening for feed 1 is connected with burning shaft furnace 4, described scavenging air valve 2 is connected with burning shaft furnace 4, described burning shaft furnace 4 is connected with cross aisle 12 one end, described cross aisle 12 one end is connected with non-burning stove 9, described burning shaft furnace 4 is connected by cross aisle 12 with non-burning stove 9, described non-burning stove 9 is connected with waste gas outlet 10, described waste gas outlet 10 is at non-burning stove 9 top.Fuel only supplies one in two stoves, non-burning stove 9 heats with the waste gas of burning shaft furnace 4, revolution occurs in the interval time of setting, burning shaft furnace 4 receive by cross aisle 12 from non-burning stove 9 adverse current come fuel and gas, Wingdale can be loaded in turning period or in the warm-up cycle cycle.Burning shaft furnace 4 just completes combustion period or is accepting Wingdale load in any time of preheating cycle, and preheating and the combustion zone combustion air preheating of non-burning stove 9 and burning shaft furnace 4 can increase overall thermal effect, the quick heating of the adiabatic temperature of the flame of generation.This lime kiln device, burning shaft furnace 4 is in burning, and combustion air enters the head of burning shaft furnace by the pipeline that scavenging air valve 2 is opened, and then closes chimney and is got off by air pressure.With the heat of the Wingdale of heating by the exhaust gases before absorption of air, fuel can be run into when air arrives burning shaft furnace 4 afterbody, Wingdale enters the first cooling room 5, be provided with the first refrigerator pipe 13, second refrigerator pipe 17 in first cooling room 5, described Wingdale further enters the 3rd cooling room 15 and cools.Combustion product gases, after coflow passes through the whole calcining zone of burning shaft furnace 4, to flow into non-burning stove 9 in the same way to its top, is discharged through waste gas outlet 10 by non-burning stove 9.Meanwhile, this waste gas outlet 10 stops any combustion air to enter non-burning stove 9.The combustion gases in the exit of kiln and the heat trnasfer of combustion air is realized as the interchanger of accumulation of heat by using the Wingdale of the preheating zone of kiln.In the first loop cycle, Wingdale absorbs the heat in emission gases, and in the second loop cycle, returns heat to combustion air.Owing to employing two or more connection shaft furnaces of burning preheating, and the flow direction of gas is regularly reversible.
