Description
Technical field
The utility model belongs to gas burning kiln technical field, relates to a kind of gas combusting limestone kiln igniter.
Background technology
Periphery burner formula gaseous fuel lime shaft kiln (hereinafter referred to as gas burning kiln) is owing to can utilize low heat value pure blast furnace gas, disposable furnace life of kiln is rotary kiln, sleeve kiln flow the two thorax kiln of accumulation of heat and will grow comparatively, the advantages such as operation rate is high, operating cost is low, ton product-specific investments is little, one of main kiln type being still steel and iron industry production metallurgy lime.
The operation principle of gas burning kiln is that the lime stone with certain lumpiness is added from the top of kiln, due to the effect of gravity, material moves from top to bottom, the lime calcined is drawn off by ash hoist at the bottom of kiln, fuel gas and burning required for air (combustion air) spray in kiln from the middle part of kiln, in shaft furnace, material is relative with gas flows, material from fall, gas from bottom to top, so it is a reverse-flow heat-exchange device.
Gas burning kiln building height is at about 35m, effective depth is at about 22m, internal diameter 2 ~ 4m, two rows burner is provided with altogether in kiln body middle and lower part, often arrange and 10 telescopic burners be evenly arranged along kiln body periphery are installed, angle between adjacent two burners of same row is 36 °, arranges alternate angle 18 ° between adjacent two burners up and down.Fuel gas and 20 the telescopic burners of primary air through being evenly arranged from kiln body periphery coal gas endless tube and air endless tube spray in kiln, fuel gas and combustion air enter in kiln carry out mixing, burn after the thermal-flame that generates Roasting Decomposition is carried out to lime stone.
Newly build by laying bricks or stones or stop production for a long time cooled gas burning kiln blow-on igniting time a large amount of soft, hardwood bavin and a small amount of matches such as waste diesel, waste cotton yarn need be carried to the igniting platform place be positioned at above upper row's burner; Drop into more than ash hoist blast cap at the bottom of 6 ~ 8 tons of coke to kiln 200 ~ 300mm (protection ash hoist) in kiln, then fill 15 ~ 20 tons, lime stone; Add cork bavin 100 ~ 150kg, hardwood bavin 500 ~ 700kg from the burning zone manhole of igniting platform again, then add cork bavin 50 ~ 100kg and a small amount of waste cotton yarn; The end bavin padded waters 20 ~ 25kg waste diesel, the torch lighted is dropped in stove from manhole, hardwood bavin 500 ~ 700kg is manually dropped into again after hyperactivity of fire, add bed coke 300 ~ 500kg, start to add lime stone and coke after normal 10 ~ 20 minutes until its burning, its proportioning is that every 1000kg lime stone adds coke 80 ~ 100kg, coke size 25 ~ 40mm; The row's of being dosed to burner 5 ~ 6 meters of, remove coke and only add lime stone; Instantly arrange burner place lime stone red heat or see that naked light is after 10 minutes, drawing low-pressure gas igniting (gas pressure 4000 ~ 5000Pa); Progressively be dosed to predetermined material level, after arranging burner up and down and all lighting, high pressure gas can be drawn and enter the just conventional production phase.
Therefore gas burning kiln does not have special ignition device up to now, the method for operating of rendzinas shaft kiln has been continued to use in blow-on igniting, there is blow-on igniting power consuming time, useless, waste resource, the energy, ash-laden gas to defects such as empty exhaust emission environment.
Utility model content
In order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of gas combusting limestone kiln igniter, it significantly can not only shorten light-off period, reduces labor strength and do not use the matches such as soft, hardwood bavin, coke expensive in short supply is not used yet, only can complete the ignition operation of gas burning kiln technique combustion gas by a small amount of fuel gas bottle of igniting, ash-laden gas is discharge after purification
.
The utility model solves the technical scheme that its technical problem adopts: a kind of gas combusting limestone kiln igniter, comprise 2 ~ 8 combined type igniters be arranged on gas burning kiln, this combined type igniter is connected with ignite fuel gas bottle and the portable IGNITION CONTROL case at two ends respectively by air hose and high-tension cable, wherein combined type igniter includes a gas sleeve of igniting through two ends, combined type igniter left and right, gas sleeve of igniting is arranged under being socketed in one in telescopic burner, one end that this gas sleeve of igniting stretches out the telescopic burner of lower row is connected with fuel gas bottle of igniting by air hose, a flame sighting tube is provided with above this end ignites gas sleeve, one end of flame sighting tube is fixed on the integrated end cap outside the telescopic burner of lower row, technique coal gas opening and a combustion air opening is disposed with from this end of the telescopic burner of lower row to the other end, a high-energy firing gun is then provided with in the termination of the gas sleeve of igniting of the other end.
Described fuel gas bottle of igniting is built with liquefied petroleum gas or acetylene gas.
Described gas sleeve and the air hose connecting place of igniting is provided with a gas electromagnetic valve of igniting.
Described gas burning kiln is assigned several telescopic burners of proper alignment, this telescopic burner is divided into the telescopic burner of upper row and the telescopic burner of lower row according to upper-lower position difference.
Arrange in telescopic burner and the telescopic burner of lower row on described and be all socketed with combined type igniter.
The beneficial effects of the utility model are: terminate the history that gas burning kiln for a long time continues to use traditional native shaft kiln ignition method, namely the matches such as firewood, waste diesel, waste cotton yarn and coke (or lump coal) are not re-used, only need utilize the bottled combustion gas of igniting of minute quantity, technique of can igniting combustion gas carries out blow-on igniting to gas burning kiln, this device is not only reusable, and has the significant technology economy advantages such as ignition operation technique is simple, safe and reliable, the time is short, labor strength is low, energy consumption is low, environmental pollution is little.
