Fig. 1 is a structural scheme of mechanism of the present utility model;
The A-A of Fig. 2 Fig. 1 is to sectional view;
Fig. 3 is that the B-B of Fig. 1 is to sectional view.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As Fig. 1,2, shown in 3, the utility model is by the kiln body, feeder system, firing system, discharge system, blowdown apparatus, Controlling System constitutes, the kiln body comprises shaft furnace 1, interchanger 3, platform 1, platform 2 21, support 1, support 2 23, feeding device support 30, feeder system comprises skew bridge 2, melt pit 11, elevator 17, fixed pulley 18, changed course pulley 19, skewed slot 27, truck 28, kiln feeding device 29, discharge system comprises discharge bucket 12, electromagnetic shock feeding machine 13, drainage comprises fly-ash separator 4,1# blower fan 5,2# blower fan 6, exhaust pipeline 8, chimney 14, exhaust pipeline 24, airduct 26, firing system mainly comprises 3# blower fan 7, gas line 9, airduct 10, combustion tube of furnace beam 15, periphery burner 16, airduct 25, combustion tube of furnace beam burner 31,3# blower fan 7 links to each other with airduct 10, airduct 10 is communicated with interchanger 3, combustion tube of furnace beam 15 is horizontal to be inserted in calcining position, kiln body middle part and evenly to stagger on level attitude, combustion tube of furnace beam burner 31 is arranged on the combustion tube of furnace beam 15, periphery burner 16 is installed in kiln body periphery, and its height is approaching with lower floor furnace ribbed tube burner height.Its principle of work is as follows: at first, Wingdale is under the traction of windlass, in truck, draw to kiln and push up along skew bridge, reinforced in the kiln body by the kiln feeding device, at first arrive preliminary heating zone, in the burning of calcining layer and decompose under the preheating of the high-temp waste gas that produces and carry out preheating, the lime that calcining is good constantly descends and is screened by the vibrations feeding machine simultaneously, supplies with transportation equipment by discharge bucket and transports.And the intravital bed of material of kiln also constantly descends because the continuous production of lime transports, the Wingdale of preliminary heating zone drops to the calcining layer and calcines, the lime that calcining is good drops to grieshoch and prepare to transport, waste gas continues in interchanger combustion air, coal gas to be carried out preheating behind the preheating Wingdale, last dedusting is constantly produced along with round-robin constantly carries out finished product lime after chimney is discharged.But burning system that whether a bedstone ash furnace can refine out qualified lime except good raw material is arranged is decisive role then, and one whether the bedstone ash furnace is energy-conservation depends on also whether its firing system is reasonable, so firing system is the core of a bedstone ash furnace.Firing system of the present utility model is such, coal gas (comprises blast furnace gas, coke-oven gas, mixed gas, producer gas, coal gas of converter, Sweet natural gas) carries out heat exchange by gas line through interchanger 3 and high-temp waste gas, combustion air by 3# blower fan 7 pressurization after enter interchanger and high-temp waste gas carries out heat exchange by airduct 25, the coal gas of temperature and combustion air have been improved respectively by entering (above having 5 three of combustion tube of furnace beam in combustion air pipeline 10 and the gas line 9, below two horizontal kiln body middle part calcining positions that are inserted in, on level attitude, evenly stagger) 15 and peripheral burner 16 (have 8 the cover, mounting height is identical with lower floor furnace ribbed tube burner height, be installed in kiln body periphery), air and coal gas lead to combustion tube of furnace beam 15 and peripheral burner 16 respectively, the air and the coal gas that lead to combustion tube of furnace beam 15 carry out the intensive combustion reactions by each burner 31 that its inner coal gas and air flue lead to combustion tube of furnace beam 15 under the uniform mixing of burner, emit a large amount of reaction heat, because temperature is very high in the kiln body, reach more than 1150 degree especially near the burner, in order to guarantee the works better of combustion tube of furnace beam, combustion tube of furnace beam is provided with the temperature that cooling channel (can with the also available oil cooling of water-cooled) reduces combustion tube of furnace beam and guarantees its works better.Simultaneously, lead to the coal gas of peripheral burner and air also under the effect of peripheral burner violent burning emit a large amount of heat, add the intravital Wingdale of heating kiln, make it be decomposed into lime and carbonic acid gas.Because uniform distribution catches fire a little to have adopted combustion tube of furnace beam to make on the section of kiln body everywhere all, the intravital Wingdale of even heating kiln, can reach the evenly calcining everywhere of Wingdale section, and the auxiliary calcining effect of peripheral burner makes the interior calcining layer of body of heater temperature even, and decomposition of limestone is complete, prevented that centre portions from burning not saturating or peripheral lime phenomenon overbumt and producing, improve the quality of finished product lime, and heat has been made full use of, saved the energy.
