Description

Technical Field

[0001] The utility model relates to the field of coking industry, in particular to a coke oven combustion chamber masonry dust prevention device and a coke oven combustion chamber masonry structure. Background Art

[0002] A coke oven, also known as a coke furnace, is a furnace typically constructed of refractory bricks and blocks, used to char coal to produce coke. Modern coke ovens primarily consist of a carbonization chamber, a combustion chamber, a chute area, a regenerator, and a roof area. The carbonization and combustion chambers are arranged alternately, with the regenerator located below. The chute area is located between the regenerator top and the combustion chamber bottom, with a chute connecting the regenerator and combustion chamber. Above the carbonization and combustion chambers is the roof area, and the order of construction is regenerator, chute area, combustion chamber, and roof area.

[0003] The JNDX3-6.25 ramming coke oven used in actual production is a fourth-generation 6.25-meter ramming coke oven developed in recent years by MCC Coking & Refractory, drawing on years of construction experience. The development of this coke oven fully utilized computer simulation technology to simulate the combustion conditions within the vertical flue of the coke oven combustion chamber, achieving an optimized design for the coke oven body and heating system. This ensures uniform heating throughout the furnace, reduces heat consumption during coking, and minimizes the generation of nitrogen oxides and graphite at the base of the riser tube, achieving energy savings and efficient production. The combustion chamber itself is also a complex structure, with combustion nozzles and primary, secondary, and tertiary air inlets. The heating positions, opening sizes, and distribution ratios of the various heating sections are inconsistent, necessitating careful protective measures during construction to prevent mud and other broken bricks from falling, which could complicate subsequent adjustments.

[0004] The original masonry construction plan used a protective film to control the mud and debris generated during the wall construction process. However, the film is relatively thin and easily breaks when subjected to external forces such as bricks due to its lack of strength. This can easily cause mud and bricks to fall and damage the masonry. If traditional wooden protective panels were used, they would easily create gaps and cracks between the bricks, making the bricks less tightly bonded. This caused the mud used in the combustion chamber masonry to easily fall into the bottom of the vertical fire channel inside the combustion chamber when the traditional wooden protective panels were moved, resulting in less than ideal dust protection.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a new type of coke oven combustion chamber masonry dust prevention device, which has a certain strength and is not easy to break. The petroleum asphalt base oil paper layer therein has a denser contact with the combustion chamber wall and is basically not affected by the difference in wall width. It can better maintain the cleanliness of the bottom of the vertical fire channel.

[0007] The basic concept of the technical solution of the utility model is as follows:

[0008] A masonry dust prevention device for a coke oven combustion chamber includes a first plate layer located on the upper layer and a second plate layer located on the lower layer, wherein a sponge pad layer and a petroleum asphalt paper layer are provided between the first plate layer and the second plate layer; the first plate layer, the sponge pad layer, the petroleum asphalt paper layer and the second plate layer are provided with a plurality of mounting holes correspondingly, and are connected into an integrated structure through the mounting holes.

[0009] As an example, a handle is provided on the upper surface of the first board layer.

[0010] As an example, the first board layer and the second board layer are made of wooden plywood.

[0011] As an example, a first sponge cushion layer, the petroleum asphalt tire oil paper layer and a second sponge cushion layer are sequentially arranged between the first board layer and the second board layer from top to bottom.

[0012] As an example, the petroleum asphalt base oil paper layer includes one or more layers of petroleum asphalt base oil paper.

[0013] As an example, the thickness of the wooden plywood is 5 mm, and the thickness of the sponge cushion layer is 3 mm.

[0014] As an example, the first board layer, the sponge pad layer, the petroleum asphalt tire oil paper layer and the second board layer are penetrated by combustion chamber gas holes and combustion chamber air holes.

[0015] The utility model also provides a coke oven combustion chamber masonry structure, which includes a plurality of combustion chambers separated by combustion chamber partition walls, and a coke oven combustion chamber masonry dust prevention device according to any one of the above contents is arranged above the opening of the combustion chamber.

[0016] As an example, at least one of the dust-proof devices built in the coke oven combustion chambers above the multiple combustion chambers is provided with a combustion chamber gas hole and a combustion chamber air hole.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. The utility model of the coke oven combustion chamber masonry dust prevention device has a simple structure, low material cost, short production time, high efficiency, and stronger protection ability, and is suitable for industrial promotion and use.

[0019] 2. The coke oven combustion chamber masonry dust prevention device of the utility model adopts a mixed method of wooden plywood in the upper and lower parts, cotton pad in the middle and multiple layers of petroleum asphalt paper-based oil paper, combining the respective advantages of traditional wooden protective plates, oil paper and sponge pads to produce a new structure with both strength and flexibility.

[0020] Among them, wooden plywood has certain strength and is not easy to break; petroleum asphalt paper-based oil paper is soft, can have a denser contact with the combustion chamber wall, and is basically not affected by the difference in wall width on both sides of the machine coke, which better solves the difficulty and pain point of garbage falling to the bottom of the vertical fire channel during the masonry process, ensures the uniform distribution of the longitudinal airflow in the combustion chamber in the later stage, makes the furnace temperature uniformity reach the optimal point, improves thermal efficiency, and ensures smooth production.
