An ultra-wide carbonization chamber coke oven

Abstract

This invention relates to the field of coke oven technology, and more particularly to an ultra-wide carbonization chamber coke oven. The combustion chamber is a honeycomb structure composed of multiple vertical flues, each of which is a regular hexagon or partially regular hexagon. The sidewalls of the combustion chamber facing the carbonization chamber are flat. The top of the combustion chamber has an arched structure. The average width of the carbonization chamber is 450–4000 mm, and the average width of the combustion chamber is 600–2500 mm. By arranging the vertical flues in a honeycomb pattern, the overall strength of the coke oven combustion chamber is improved, enabling it to withstand higher lateral pressure. This allows the average width of the combustion chamber to reach 600 mm or even 2500 mm, and the average width of the carbonization chamber can be expanded to 500 mm or even 4000 mm. Combined with design improvements to the carbonization chamber and the top of the oven, while achieving an ultra-wide carbonization chamber, the heating uniformity of the coke oven can be guaranteed, which is conducive to further increasing coke production and reducing energy consumption and emissions.

Description

Technical Field

[0001] This invention relates to the field of coking technology, and in particular to an ultra-wide carbonization chamber coking oven. Background Technology

[0002] The trend towards larger coke ovens primarily involves increasing the volume of the carbonization chamber. Early increases in chamber volume were mainly achieved by increasing the longitudinal (length) and lateral (height) dimensions of the carbonization chamber. The width of the carbonization chamber has never exceeded 450mm, as it is generally believed in the industry that only within this width can high productivity be achieved. Currently, the maximum height of coke oven carbonization chambers is approaching 9m. Considering factors such as the cost of coke oven refractory materials and equipment manufacturing, the current height of the carbonization chamber is nearing its limit. However, through long-term production practice, it has been discovered that to ensure smooth coke oven operation, in addition to increasing the length and height of the carbonization chamber, it is also necessary to appropriately increase its width.

[0003] Ultra-wide carbonization chambers typically refer to carbonization chambers with a width greater than 500mm. Compared to conventional coke ovens with a carbonization chamber width of less than 450mm, ultra-wide carbonization chambers can significantly increase the volume and capacity of a single chamber, and bring many advantages such as energy saving and environmental protection. They are beneficial for improving the production efficiency of coke ovens and reducing energy consumption and emissions, and therefore have become the direction for the further development of modern coke ovens.

[0004] While ultra-wide carbonization chamber coke ovens offer significant advantages, they also face a series of technical challenges and potential problems in actual design, construction, and operation. These include stricter requirements for coking coal quality, increased risk of expansion pressure, more complex heating regimes, and greater difficulty in controlling temperature uniformity. In particular, the increased width of the carbonization chamber means a significant increase in the amount of coal charged per chamber. During the coking process, the expansion pressure generated by the dry distillation of coal (especially during the maximum expansion stage before the semi-coke shrinkage stage) will increase significantly. If the cohesiveness and expansion properties of the coal are not properly controlled, the enormous expansion pressure may directly lead to deformation and cracking of the furnace wall, or even bending of the coke pusher.

[0005] To address the aforementioned issues, it is necessary to break away from conventional coke oven structural design thinking and develop new coke oven structures, especially combustion chamber structures, to solve the problem that existing coke oven combustion chamber structures cannot withstand the enormous lateral pressure caused by ultra-wide carbonization chambers. Summary of the Invention

[0006] This invention provides an ultra-wide carbonization chamber coke oven. By using a honeycomb-shaped vertical fire channel structure, the overall strength of the coke oven combustion chamber is improved, enabling it to withstand higher lateral pressure. This results in an average combustion chamber width of 600mm or even 2500mm, corresponding to an average carbonization chamber width that can be extended to 500mm or even 4000mm. Combined with design improvements to the carbonization chamber and furnace top, while achieving an ultra-wide carbonization chamber, the invention also ensures uniform heating of the coke oven, which is conducive to further increasing coke production and reducing energy consumption and emissions.

[0007] To achieve the above objectives, the present invention employs the following technical solution: An ultra-wide carbonization chamber coke oven includes a coke oven consisting of a small flue, a regenerator, an inclined flue, a combustion chamber, a carbonization chamber, and a furnace roof; the combustion chamber and the carbonization chamber are arranged alternately, the combustion chamber is a honeycomb structure composed of multiple vertical flues, each vertical flue is a regular hexagon or partially regular hexagon, and the side wall of the combustion chamber facing the carbonization chamber is a plane; the furnace roof area at the top of the combustion chamber has an arched structure; the average width of the carbonization chamber is 450-4000 mm, and the average width of the combustion chamber is 600-2500 mm.

[0008] The combustion chamber consists of two rows of parallel longitudinal double-connected vertical flues; each combustion chamber along the longitudinal direction of the coke oven includes two rows of vertical flues, and each row of vertical flues along the coke oven machine side-coke side direction consists of multiple regular hexagonal vertical flues; two adjacent vertical flues along the longitudinal direction of the coke oven form a double-connected vertical flue, the top of the double-connected vertical flues are connected by a cross-hole, and the bottom is connected by a waste gas recirculation hole; the bottom of each vertical flue is provided with a blast furnace gas inclined flue outlet, an air inclined flue outlet, and a coke oven gas lamp head brick, and three adjacent regular hexagonal... Air passages are set in the Y-shaped partition wall at the intersection of the hexagonal vertical flues, and each air passage has 1 to 5 air outlets along the height. When the coke oven is heated by blast furnace gas, air is supplied into the vertical flue from the air inclined outlet at the bottom of the vertical flue and from each section of the air outlet, and mixes and burns with the blast furnace gas supplied from the blast furnace gas inclined outlet at the bottom of the vertical flue. The air and blast furnace gas supplied into the vertical flue are preheated through the small flue, regenerator and inclined flue.

[0009] The combustion chamber consists of two rows of parallel transverse double-connected vertical flues; each combustion chamber along the longitudinal direction of the coke oven includes two rows of vertical flues, and along the coke oven machine side-coke side direction, each row of vertical flues consists of multiple regular hexagonal vertical flues; two adjacent vertical flues along the transverse direction of the coke oven form a double-connected vertical flue, the top of the double-connected vertical flues are connected by a cross-hole, and the bottom is connected by a waste gas recirculation hole; the bottom of each vertical flue is equipped with a blast furnace gas inclined flue outlet, an air inclined flue outlet, and a coke oven gas lamp head brick, with three adjacent regular hexagonal... Air passages are set in the Y-shaped partition wall at the intersection of the hexagonal vertical flues, and each air passage has 1 to 5 air outlets along the height. When the coke oven is heated by blast furnace gas, air is supplied into the vertical flue from the air inclined outlet at the bottom of the vertical flue and from each section of the air outlet, and mixes and burns with the blast furnace gas supplied from the blast furnace gas inclined outlet at the bottom of the vertical flue. The air and blast furnace gas supplied into the vertical flue are preheated through the small flue, regenerator and inclined flue.

[0010] The combustion chamber is composed of a triangular array of transverse double vertical combustion channels. Along the coke oven machine side-coke side direction, odd-numbered and even-numbered vertical combustion channels are alternately arranged. The odd-numbered vertical combustion channels consist of two rows of regular hexagonal vertical combustion channels, while the even-numbered vertical combustion channels consist of a central regular hexagonal vertical combustion channel and half-regular hexagonal vertical combustion channels on both sides. The odd-numbered vertical combustion channels and the regular hexagonal vertical combustion channels in the middle of adjacent even-numbered vertical combustion channels form a triangular array of vertical combustion channels. The two vertical combustion channels in the same row of two adjacent odd-numbered vertical combustion channels form a double vertical combustion channel. The top of the double vertical combustion channels is connected by a cross-hole, and the bottom is connected by a waste gas recirculation hole. The bottom of the odd-numbered vertical flues is equipped with blast furnace gas inclined outlets and coke oven gas lamp head bricks; the bottom of the hexagonal vertical flue in the middle of the even-numbered vertical flues is equipped with an air inclined outlet, and multiple air outlets are provided along the height of the partition wall between the hexagonal vertical flue and the adjacent odd-numbered vertical flues; when the coke oven is heated by blast furnace gas, the blast furnace gas is supplied from the blast furnace gas inclined outlet at the bottom of the rising gas flow vertical flue, and the air enters from the air inclined outlet at the bottom of the rising air flow vertical flue, and is supplied into the rising gas flow vertical flue through each section of the air outlet to mix and burn with the blast furnace gas.

[0011] The combustion chamber consists of three rows of parallel transverse double-connected vertical fire channels; each combustion chamber along the longitudinal direction of the coke oven includes three rows of vertical fire channels; along the coke oven machine side-coke side direction, two adjacent vertical fire channels in the outer two rows form a double-connected vertical fire channel, with the top of the double-connected vertical fire channels connected by a cross-hole and the bottom connected by a waste gas circulation hole; each vertical fire channel in the double-connected vertical fire channel has a blast furnace gas inclined outlet and a coke oven gas pipe brick lamp head brick at the bottom; the bottom of the middle row of vertical fire channels has an inclined air outlet; when the coke oven is heated by blast furnace gas, the blast furnace gas enters the gas regenerator through the small flue for heat exchange and is then distributed through the blast furnace gas inclined channel and supplied from the bottom of the corresponding vertical fire channel; the combustion air enters the air regenerator through the small flue for heat exchange and is then distributed through the air inclined channel and supplied from the bottom of the corresponding vertical fire channel into the rising gas flow vertical fire channel to mix and burn with the blast furnace gas.

[0012] A gas channel is set up in the Y-shaped partition wall at the intersection of the three adjacent vertical flues in the combustion chamber, which is connected to the blast furnace gas inclined channel. The gas channel has multiple gas outlets along the vertical direction, which are connected to the corresponding vertical flues. When the coke oven is heated by blast furnace gas, the blast furnace gas enters the regenerator through the small flue for heat exchange, and then is distributed through the blast furnace gas inclined channel to be supplied to the bottom of the corresponding vertical flue and the gas channel respectively. The blast furnace gas mixes and burns with the combustion air supplied to the bottom and each section along the vertical direction to achieve segmented heating in the vertical direction.

[0013] The combustion chamber is composed of staggered arrays of transverse double vertical flues. Along the coke oven machine side-coke side direction, each column of vertical flues consists of one regular hexagonal vertical flue and half a regular hexagonal vertical flue, with adjacent columns of vertical flues staggered. Two regular hexagonal vertical flues in two adjacent columns form a double vertical flue, with the top of the double vertical flues connected by a cross-hole and the bottom connected by a waste gas recirculation hole. Each vertical flue forming the double vertical flue has a blast furnace gas inclined outlet at its bottom. Each half of the regular hexagonal vertical flue has an air inclined outlet at its bottom. The partition wall between the half of the regular hexagonal vertical flue and the adjacent regular hexagonal vertical flue has multiple air outlets along the vertical direction. When the coke oven is heated by blast furnace gas, the blast furnace gas is supplied into the corresponding vertical flue from the blast furnace gas inclined outlet, and the combustion air is supplied into the corresponding vertical flue from the air inclined outlet. The vertical flue from each section of the air outlet is supplied with rising gas flow. The air and blast furnace gas are mixed and burned to achieve high-level segmented heating.

[0014] Gas channels are provided at both ends of the partition wall of the double-connected vertical flue. The gas channels have multiple gas outlets along the vertical direction that are connected to the corresponding two vertical flues. When the coke oven is heated by blast furnace gas, the blast furnace gas is distributed by the blast furnace gas inclined channel. Part of the gas is supplied to the corresponding vertical flue from the outlet of the blast furnace gas inclined channel, and the other part is supplied to the corresponding vertical flue through the gas outlets of each section of the gas channel. The gas supplied in multiple sections is mixed and burned in stages with the combustion air supplied in multiple sections.

[0015] The bottom surface of the carbonization chamber is 50-500mm higher than the bottom surface of the combustion chamber, and the bottom surface of the carbonization chamber is a trapezoidal surface that is narrower at the bottom and wider at the top; the furnace top area corresponding to the carbonization chamber is provided with more than two rows of coal charging holes.

[0016] The inclined zone is enclosed by the top surface of the regenerator, the bottom surface of the carbonization chamber, the air inclined channel, the gas inclined channel, and the coke oven gas pipe bricks. One or more layers of heat insulation structure are set up in the area. The heat insulation structure is composed of lightweight silica bricks.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1) By using a honeycomb-shaped vertical fire channel structure to improve the overall strength of the coke oven combustion chamber, it can withstand higher lateral pressure, thereby achieving an average width of 600mm or even 2500mm for the combustion chamber. The corresponding average width of the carbonization chamber can be expanded to 500mm or even 4000mm, thus increasing the output of the single-hole carbonization chamber of the coke oven.

[0018] 2) After the combustion chamber adopts a honeycomb vertical fire channel structure, it is scientifically divided according to different arrangements to form multiple different airflow channels. Combined with high-directional multi-stage heating technology, the coke oven has an ultra-wide carbonization chamber while ensuring the uniformity of coke oven heating.

[0019] 3) The bottom height of the carbonization chamber is appropriately increased relative to the combustion chamber to meet the heat load requirements of the carbonization chamber.

[0020] 4) In response to the increase in the amount of coal charged in the carbonization chamber, the furnace top has also been improved accordingly, and double or multiple rows of coal charging holes have been set to meet the needs of rapid coal charging.

[0021] 5) With the center distance of the carbonization chambers greatly increased, energy-saving materials can be applied to the inclined duct design, thereby reducing the overall construction cost of the coke oven. Attached Figure Description

The air and blast furnace gas supplied into the vertical flue are preheated through the small flue, regenerator and inclined flue.

[0032] like Figure 3 As shown, the combustion chamber is composed of a triangular array of transverse double vertical combustion channels. Along the coke oven machine side-coke side direction, odd-numbered and even-numbered vertical combustion channels are alternately arranged. The odd-numbered vertical combustion channels consist of two rows of regular hexagonal vertical combustion channels, while the even-numbered vertical combustion channels consist of a central regular hexagonal vertical combustion channel and half-regular hexagonal vertical combustion channels on both sides.

[0033] like Figure 4 As shown, the combustion chamber consists of three rows of parallel transverse double-connected vertical fire channels; each combustion chamber along the longitudinal direction of the coke oven includes three rows of vertical fire channels; along the coke oven machine side-coke side direction, two adjacent vertical fire channels in the outer two rows form a double-connected vertical fire channel, the top of the double-connected vertical fire channels are connected by a cross-hole, and the bottom is connected by a waste gas circulation hole; each vertical fire channel in the double-connected vertical fire channel has a blast furnace gas inclined outlet and a coke oven gas pipe brick lamp head brick at the bottom; the bottom of the middle row of vertical fire channels has an inclined air outlet; when the coke oven is heated by blast furnace gas, the blast furnace gas enters the gas regenerator through the small flue for heat exchange and is then distributed through the blast furnace gas inclined channel and supplied from the bottom of the corresponding vertical fire channel; the combustion air enters the air regenerator through the small flue for heat exchange and is then distributed through the air inclined channel and supplied from the bottom of the corresponding vertical fire channel into the rising gas flow vertical fire channel to mix and burn with the blast furnace gas.

[0034] A gas channel is set up in the Y-shaped partition wall at the intersection of the three adjacent vertical flues in the combustion chamber, which is connected to the blast furnace gas inclined channel. The gas channel has multiple gas outlets along the vertical direction, which are connected to the corresponding vertical flues. When the coke oven is heated by blast furnace gas, the blast furnace gas enters the regenerator through the small flue for heat exchange, and then is distributed through the blast furnace gas inclined channel to be supplied to the bottom of the corresponding vertical flue and the gas channel respectively. The blast furnace gas mixes and burns with the combustion air supplied to the bottom and each section along the vertical direction to achieve segmented heating in the vertical direction.

[0035] like Figure 5As shown, the combustion chamber is composed of staggered arrays of transverse double vertical combustion channels; along the coke oven machine side-coke side direction, each row of vertical combustion channels consists of one regular hexagonal vertical combustion channel and half a regular hexagonal vertical combustion channel, and adjacent rows of vertical combustion channels are staggered; two regular hexagonal vertical combustion channels in two adjacent rows of vertical combustion channels form a double vertical combustion channel, the top of the double vertical combustion channel is connected by a cross-hole, and the bottom is connected by a waste gas recirculation hole; each vertical combustion channel forming the double vertical combustion channel is provided with a blast furnace gas inclined channel at its bottom.

[0037] like Figure 6 As shown, the bottom surface 3 of the carbonization chamber is 250-500mm higher than the bottom surface 2 of the combustion chamber. This is to compensate for the defect of insufficient heat supply to the bottom of the carbonization chamber caused by the flame position being too high during segmented heating. The bottom surface 3 of the carbonization chamber is a trapezoidal surface that is narrower at the bottom and wider at the top, which is to further strengthen the bottom of the combustion chamber and prevent the furnace wall at the bottom of the combustion chamber from wearing out too quickly. Two or more rows of coal charging holes are provided in the furnace top area corresponding to the carbonization chamber to solve the problems of prolonged coal charging time and uneven coal charging caused by the dramatic increase in coal charging capacity in the ultra-wide carbonization chamber.
