The practical implementation instance
To combine accompanying drawing and embodiment to come the utility model is done further detailed explanation below.
Like Fig. 1; Shown in Figure 2, the utility model is a kind of combustion chamber zone heating, the adjustable tamping coke furnace of regenerator lattice, comprises furnace roof 1, coking chamber 2, combustion chamber 3, chute 4, regenerator 5, bottom flue 6; Said furnace roof 1 is positioned at coking chamber 2 and 3 tops, combustion chamber; Said coking chamber 2 distributes alternately with combustion chamber 3, and said regenerator 5 is positioned at coking chamber 2 and 3 bottoms, combustion chamber, links to each other with combustion chamber 3 through chute 4; Said coking chamber 2 by two side coking chamber walls 7, furnace roof 1, coking chamber at the bottom of 8 and two wing furnace doors 9 surround and form; Said combustion chamber 3 is by flue 11, flue partition 15; Coking chamber wall 7, pusher side burner 12 and coke side burner 14 are formed, and said combustion chamber 3 is divided into two section 32 of one section 31 of combustion chamber and combustion chamber.
The height of coking chamber 2 is 6.3m, and width average is 550mm, belongs to wide coking chamber type, and thermograde is little in the coking chamber like this, and the coking speed of coal charge is slowed down, and the lumpiness of coke increases, crackle reduces, and the M40 that improves coke is had bigger benefit; The tapering of coking chamber 2 is 40mm, has reduced coke pushing resistance and the coke pushing loss to furnace wall, and its heat levels height is 800mm, can make charge of coke ripe simultaneously up and down, reduces the generation of furnace roof 1 space graphite, guarantees that coking chamber 2 height are to homogeneous heating.Coking chamber 2 shop fixtures bricks are fine and close silica brick, and thickness is 120mm, bigger raising the wear-resisting and impact resistance of coke oven shop fixtures brick, coking chamber 2 walls adopt brick the building of " pagoda " shape.
The adjustable bamboo comb brick 50 of the regenerator 5 of the utility model increases adjustable structure 51; Adjustable structure 51 position and placed are changed to (2-4) piece brick; Through the quantity of increase/minimizing brick, can reach area, the inflow of pilot-gas and the effusive amount of control adjustable structure 50.
In the process of building regenerator 5 by laying bricks or stones; Regenerator main wall 52 is formed by the mutual occlusal masonry of the shaped brick that has three ditch tongues; Regenerator 5 is divided into gas regenerator 54 and air regenerator 55 (shown in Fig. 5 is the synoptic diagram of a regenerator) through main wall 52, single wall 56, and regenerator 5 built-in checker brick, is used for the heat of absorbing waste gas when the regenerator downdraft; And a heat that absorbs passes to air and low-grade gas when the regenerator upstream; Play preheating and go into stove air and coal gas effect, thereby improve the hot working efficiency of coke oven, chute 4 is provided with gas exit 41, one section air and 42 and two sections air of low-grade gas outlet and low-grade gas outlet 43.
In order to reach sealing and heat insulation effect, regenerator 5 envelopes are used for ceramic beaverboard within the walls, and thickness is 30mm, and regenerator 5 envelope walls use the silicate lagging material outward, and thickness is 70mm.
The coke oven of the utility model is designed to the segmentation heating mode; Combustion chamber 3 is divided into two section 32 of one section 31 of combustion chamber and combustion chamber; The working process of whole coke oven heating system does, low-grade gas and air pass through waste gas valve, bottom flue 6, regenerator 5, chute 4 respectively, and low-grade gas and air are divided into two portions at chute 4; Flue 11 base burnings that a part is one section 31 in the combustion chamber, the flue 11 middle parts burning that another part is two section 32 in the combustion chamber.Waste gas after burning changes the another one flue over to through leap hole 10 and gets into regenerator 5 at last, with the heat transferred checker brick, discharges through bottom flue 6, waste gas valve, branch flue, set flue, main flue, chimney.Part waste gas flows into flue 11 (upstream) through circulation pore 13 in the combustion processes; Waste gas circulation makes in the rising flue coal gas that the concentration of oxygen reduces in the combustiblecomponents and air; Gas velocity increases, and combustionvelocity slows down, and flame elongates; Thereby help charge of coke homogeneous heating up and down, improve coke quality.
The foregoing description is the utility model preferred implementation; But the embodiment of the utility model is not restricted to the described embodiments; Other any do not deviate from change, the modification done under spirit and the principle of the utility model, substitutes, combination, simplify; All should be the substitute mode of equivalence, be included within the protection domain of the utility model.
