Description

Technical Field

[0001] The present invention relates to the technical field of coking, and more particularly to a regenerator structure of a coke oven and a coke oven. Background Art

[0002] At present, the development of coke ovens is showing a trend of large-scale development. The weight of the coke oven's own masonry is increasing, the amount of coal loaded is increasing, and the mechanical equipment is getting larger and heavier, resulting in the heat storage chamber structure located at the bottom of the coke oven borne by an increasingly larger load.

[0003] See also Figure 1 The regenerator structure in the existing coke oven is supported by the main wall 13 and the single wall 12, and has limited load-bearing capacity and cannot adapt to the development trend of large-scale coke ovens.

[0004] In addition, the regenerator structure includes a small air regenerator flue 16 and a small gas regenerator flue 18 at the lower part, as well as an air regenerator 14 and a gas regenerator 17 at the upper part. As the coke oven becomes larger, the air regenerator 14 and the gas regenerator 17 are widened, resulting in the lengthening of the checker bricks 15 in the air regenerator 14 and the gas regenerator 17. This reduces the structural strength of the checker bricks 15 and creates a risk of breakage and falling off.

[0005] Furthermore, the widening of the air heat storage chamber 14 and the gas heat storage chamber 17 also causes the inclined bottom bricks 11 to protrude for a long length, resulting in low strength of the inclined bottom bricks 11 and a high risk of breakage and falling off.

[0006] In summary, how to solve the problem in the prior art that the regenerator structure is supported only by the main wall and a single wall, has limited load-bearing capacity, and cannot adapt to the development trend of large-scale coke ovens is an urgent problem to be solved by those skilled in the art.

DETAILED DESCRIPTION

[0029] Embodiments of the present invention disclose a regenerator structure for a coke oven. The structure comprises not only a main wall and a single wall, but also a load-bearing partition wall disposed between the main wall and the single wall. The load-bearing partition wall can bear a portion of the load, reducing the load borne by the main wall and the single wall, thereby increasing the overall structural strength of the regenerator structure and improving its load-bearing capacity, thereby adapting to the current trend of larger coke ovens. The present invention also provides a coke oven utilizing the above-described regenerator structure, facilitating its development towards larger sizes.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] See also Figure 2An embodiment of the present invention provides a regenerator structure of a coke oven, comprising a main wall 301 and a single wall 201 , and further comprising a load-bearing partition wall arranged between the main wall 301 and the single wall 201 .

[0032] In the regenerator structure provided by the embodiment of the present invention, the load-bearing partition wall can bear part of the load, reducing the load borne by the main wall 301 and the single wall 201, increasing the overall structural strength of the regenerator structure, improving the load-bearing capacity, and adapting to the current development trend of large-scale coke ovens.

[0033] In the above-mentioned heat storage chamber structure, there are multiple load-bearing partition walls, including an air heat storage chamber partition wall 401 and a gas heat storage chamber partition wall 402;

[0034] The air heat storage chamber partition wall 401 divides the air heat storage chamber 601 between the main wall 301 and the single wall 201 into multiple parts, and divides the air heat storage chamber small flue 801 between the main wall 301 and the single wall 201 into multiple parts;

[0035] The gas regenerator partition wall 402 divides the gas regenerator 701 between the main wall 301 and the single wall 201 into multiple parts, and divides the gas regenerator small flue 901 between the main wall 301 and the single wall 201 into multiple parts.

[0036] Specifically, in the above heat storage chamber structure, the air heat storage chamber partition wall 401 is one surface.

[0037] The air heat storage chamber partition wall 401 divides the air heat storage chamber 601 into two, including the segmented air heat storage chamber 6011 and the bottom air heat storage chamber 6012; the air heat storage chamber partition wall 401 divides the air heat storage chamber small flue 801 into two, including the segmented air heat storage chamber small flue 8011 and the bottom air heat storage chamber small flue 8012.

[0038] In the above-mentioned regenerator structure, the bottom air regenerator 6012 corresponds to the bottom air outlet of the combustion chamber of the coke oven; the segmented air regenerator 6011 corresponds to the segmented outlet of the combustion chamber of the coke oven.

[0039] Specifically, in the above heat storage chamber structure, the gas heat storage chamber partition wall 402 is one surface.

[0040] The gas regenerator partition wall 402 divides the gas regenerator 701 into two, including the segmented gas regenerator 7011 and the bottom gas regenerator 7012; the gas regenerator partition wall 402 divides the gas regenerator small flue 901 into two, including the segmented gas regenerator small flue 9011 and the bottom gas regenerator small flue 9012.

[0041] The bottom gas regenerator 7012 corresponds to the bottom gas outlet of the combustion chamber of the coke oven; the segmented gas regenerator 7011 corresponds to the segmented gas outlet of the combustion chamber of the coke oven.

[0042] In the above-mentioned heat storage chamber structure, the load-bearing partition wall, the main wall 301 and the single wall 201 are parallel to each other.

[0043] The regenerator structure provided in this embodiment includes air regenerator partition walls 401 and gas regenerator partition walls 402. This reduces the width of the air regenerator 601 and gas regenerator 701, shortening the length of the checker bricks 501 within the air regenerator 601 and gas regenerator 701. This increases the strength of the checker bricks 501 and reduces the risk of breakage. Furthermore, the reduced length of the checker bricks 501 facilitates manufacturing.

[0044] Furthermore, in the technical solution provided in this embodiment, the load-bearing partition wall reduces the width of the air heat storage chamber 601 and the gas heat storage chamber 701, so that the length of the inclined bottom brick 101 is set to be smaller, thereby improving the strength of the inclined bottom brick 101 and reducing the risk of the inclined bottom brick 101 breaking and falling off.

[0045] At the same time, in the regenerator structure provided in this embodiment, the air regenerator 601 is divided into a segmented air regenerator 6011 and a bottom air regenerator 6012, the gas regenerator 701 is divided into a segmented gas regenerator 7011 and a bottom gas regenerator 7012, the air regenerator small flue 801 is divided into a segmented air regenerator small flue 8011 and a bottom air regenerator small flue 8012, and the gas regenerator small flue 901 is divided into a segmented gas regenerator small flue 9011 and a bottom gas regenerator small flue 9012, so that the distribution of air and gas is more reasonable and suitable for the actual needs of large-scale coke oven production.

[0046] The preceding description describes a coke oven using mixed coal gas (lean coal gas) as the heating medium. The structure of the present invention is equally applicable when using rich coal gas (coke oven gas) as the primary heating medium, differing only in the heating medium entering. When using rich coal gas (coke oven gas) as the primary heating medium, the gas regenerator receives combustion-supporting air and exhausts waste gas. The regenerator structure provided by the present invention is suitable for coke ovens heated solely by rich coal gas, lean coal gas, and a combination of rich and lean coal gas, with furnace heights of 5-10 meters.

[0047] An embodiment of the present invention further provides a coke oven, comprising a regenerator structure, wherein the regenerator structure is the regenerator structure provided in the above embodiment.

[0048] The coke oven provided by the embodiment of the present invention applies the regenerator structure provided by the above embodiment, which is convenient for development in the direction of large-scale. Of course, the coke oven provided by this embodiment also has other effects related to the regenerator structure provided by the above embodiment, which will not be repeated here.

[0049] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0050] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
