Abstract
The utility model relates to an oven body of a coke oven which is characterized in that a blast chamber is divided into vertical flame paths, and every two vertical flame paths form a group; duplex flame paths with spanning bores are arranged on division walls in the blast chamber, and coke oven gas is only used for heating; coke oven gas sprays sideward, and two rows of inclined flues of an inclined flue region are simplified to a one-row form. The oven body of coke oven has the advantages of reasonable structure, long life time, even heating, high hot work efficiency, small heating system resistance, good quality of the produced coke and investment saving; the oven body of coke oven is especially suitable for middle-sized and small-sized coke ovens.
Description
The utility model relates to a kind of pit kiln, particularly a kind of duplex side spray heat type one Coke Oven Proper structure.
At present, the body of heater of pit kiln mainly contains following two kinds of forms both at home and abroad: (1) combustion chamber is quirk, the spray of coke-oven gas side or spray down in two minutes.Its structure of this coke oven is comparatively simple, reduced investment, and the homonymy air flow line is identical, is difficult for gas leakage, but also exist the firing system resistance bigger, hot working efficiency is low, fragile body of heater, cross wall non-uniform temperature, end flue temperature is low, and the coke quality of production is relatively poor, furnace binding intensity a little less than, the life-span is low; Therefore, can only be adapted to the less middle-size and small-size coke oven of coking chamber length; (2) combustion chamber is the complex thermal coke of duplex, the spray of coke-oven gas side or following spray, it is rational in infrastructure, and is firm, and converter life is long, homogeneous heating, regulating measure is simple, accurate, and the coke quality of production is good, the hot working efficiency height, but its oblique flue plot structure complexity, incorgruous air-flow contact surface is more, and investment is big, never adopts on middle-size and small-size coke oven.
The purpose of this utility model is to provide a kind of duplex side spray heat type one Coke Oven Proper; Its characteristics are single with the coke-oven gas heating, the spray of coke-oven gas side, and the combustion chamber is divided into one group of two lattice, and tiltedly the oblique flue of two of flue district rows is reduced to the oblique flue of a row.
For realizing this purpose, the technical measures that the utility model is taked are:
A kind of Coke Oven Proper, it is made up of furnace roof district, combustion chamber district, oblique flue district and regenerator district, its combustion chamber and coking chamber are alternately, two of the flues of combustion chamber are one group, bottom at oblique flue is provided with two horizontal brick gas passages, each flue that it is characterized in that the combustion chamber connects an oblique flue, and the odd number of combustion chamber is connected with two adjacent regenerator by oblique flue respectively with the even numbers flue.
The advantage of a kind of Coke Oven Proper of the utility model is: (1) furnace binding is firm, and the life-span is long; (2) rational in infrastructure, homogeneous heating, regulating measure is simple, the hot working efficiency height, the coke quality of production is good; (3) the heating system resistance is little, is convenient to the stable operation of coke oven; (4) reduced investment is specially adapted to middle-size and small-size coke oven.
Introduce the detailed content of a kind of Coke Oven Proper of the utility model below in conjunction with drawings and Examples.
Fig. 1 is a kind of structure iron of Coke Oven Proper.
Fig. 2 is a kind of structure side view of Coke Oven Proper.
Among the embodiment as shown in Figure 1 and Figure 2, coke-oven gas by horizontal brick gas passage 9 enter even numbers combustion chamber 5 (2H, 4H ...) even numbers flue 8 (2A, 4A ... 24A) and odd number combustion chamber 5 (1H, 3H ...) odd number flue 8 (1A, 3A ... height lamp holder 12 23A) and nozzle 13; Air is by even numbers regenerator 7 (2K, 4K ...) enter the even numbers flue 8 (2A of even numbers combustion chamber 5 through oblique flue 6,4A, 24A) and the odd number flue 8 (1A of odd number combustion chamber 5,3A, 23A), the afterfire of meeting of coke-oven gas and air, flue 8 tops of the waste gas that 8 burnings of the even numbers flue 8 of even numbers combustion chamber 5 and the odd number flue of odd number combustion chamber 5 generate by upstream are through crossing over the flue 8 of downdraft that hole 10 changes the even numbers flue 8 of the odd number flue 8 of even numbers combustion chamber 5 and odd number combustion chamber 5 over to, enter odd number regenerator 7 (1K through oblique flue 6 again, 3K,) in, waste gas is passed to checker brick with most of institute heat content in regenerator 7 after, efflux via bottom flue 11, through commutating after the heating in 20~30 minutes, the gas flow direction after the commutation is opposite with preceding process.
8 two of the flues of combustion chamber 5 are one group of (1A, 2A, 3A, 4A, 23A, 24A,), on every group of flue partition 16, be provided with one and cross over hole 10,5 odd number is connected with two adjacent regenerator 7 by oblique flue 6 respectively with the even numbers flue in the combustion chamber, tiltedly flue 6 suitable for reading being provided with are regulated the air capacity that brick is used for regulating flue 8, bottom at the oblique flue 6 of each combustion chamber 5 is provided with two horizontal brick gas passages 9, and in the disconnection of center partition 15 places, horizontal brick gas passage 9 is connected by height lamp holder 12 with flue 8, and wherein a horizontal brick gas passage 9 is connected with odd number flue 8, another horizontal brick gas passage 9 is connected with even numbers flue 8, and be staggered, height lamp holder 12 is provided with nozzle 13, is used for regulating the coke-oven gas amount of flue 8, combustion chamber 5 and coking chamber 18 are alternately, wide during when coking chamber 18 at 485~520mm, can produce the bigger coke of lumpiness, and reduce the coke pushing number of times, improve environment protecting, coking chamber 18 height can design in 2500~3300mm scope; Be provided with diffusion type grate brick 14 on bottom flue 11 tops,, become collapsible tube at burner position macropore down,, become diffuser tube near central wall 15 place's macropores up, rise and the pressure distribution of downdraft in bottom flue 11 to adapt to; When adopting the top to coaling form, be provided with three or four and arrange coaling hole and one or two row's rising pores on furnace roof, when adopting the stamp charging form, furnace roof is provided with two or three row smoke elimination holes and one or two row's rising pores.
