Description

Technical Field

[0001] The invention belongs to the technical field of horizontal heat recovery coke oven quenching vehicles, and in particular relates to a novel bottom plate used for a horizontal heat recovery coke oven quenching vehicle and a quenching method. Background Art

[0002] Wet quenching is a method of cooling high-temperature coke by water spraying. The process mainly includes the following steps: First, the red coke from the coke oven is pushed into the coke receiving trough of the coke quenching car and then transported to the coke quenching tower. In the coke quenching tower, the high-temperature coke is cooled and quenched by water spraying. After quenching, the coke receiving trough tilting mechanism pushes the coke receiving trough to tilt around its hinge point to the outlet side to unload the coke, and the coke is sent to the coke cooling platform for further cooling and evaporation of water.

[0003] The quenching car is a supporting equipment of the coke oven. It usually runs on the track under the coke side of the coke oven. It is used to receive the high-temperature coke pushed out by the coke pusher and transport it to the coke quenching tower for quenching, and finally transport the quenched coke to the coke cooling platform.

[0004] During quenching, the quenching car enters the quenching tower and is quenched by water spray. Since the temperature at the center of the hot coke is higher and the spraying water can only contact the surface of the coke, the center of the coke can only rely on the slowly infiltrating quenching water. Therefore, the cooling efficiency is low, the quenching time is long, the power consumption is high, and a large amount of circulating water resources are wasted. Summary of the invention

[0005] In view of this, the purpose of the present invention is to provide a new bottom plate and quenching method for a horizontal heat recovery coke oven quenching car to address the deficiencies of the prior art, thereby increasing the contact area between quenching water and coke and improving quenching efficiency.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A novel bottom plate for a horizontal heat recovery coke oven quenching vehicle comprises a coke receiving bottom plate arranged in a coke receiving groove, wherein the coke receiving bottom plate is an arc-shaped structure bent downward in the width direction.

[0008] In order to better implement the present invention, further optimization is made in the above structure, the focus-joining bottom plate is formed by splicing a plurality of folding plates in the width direction, and an inclined angle is set between the upper surfaces of every two adjacent folding plates.

[0009] In order to better realize the present invention, further optimization is made in the above structure, a rear baffle and a front baffle are arranged on the coke receiving groove, and a movable baffle is arranged on the front baffle.

[0010] A coke quenching method, using the novel bottom plate for a horizontal heat recovery coke oven quenching vehicle, comprises the following steps:

[0011] The coke pushing device pushes the cubic coke block from the end into the coke receiving groove and moves continuously on the coke receiving bottom plate;

[0012] As the cubic coke block continues to move, the suspended part of the cubic coke block on the coke receiving bottom plate breaks by itself under the action of gravity until it breaks and splits into several pieces;

[0013] The broken cubic coke blocks are transported to the coke quenching tower by a quenching car for water spray quenching.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The novel bottom plate for the horizontal heat recovery coke oven quenching car provided by the present invention replaces the traditional flat coke receiving bottom plate with a downward curved coke receiving bottom plate, so that the cubic coke block breaks into pieces of coke cakes by itself under the action of gravity, thereby increasing the surface area of ​​the cubic coke block, allowing the quenching water to enter the center of the coke cake through the cracks, and increasing the contact area between the quenching water and the coke. Secondly, the coke receiving bottom plate is designed as a structure formed by splicing multiple folding plates in the width direction, so that the cubic coke block can be broken at the bend between two adjacent folding plates, thereby controlling the number and size of cracks in the coke cake after breaking.

[0016] 2. The quenching method provided by the present invention enables the quenching car to enter the quenching tower and be quenched by water spraying, and the quenching water flows into the coke cake through the cracks to increase the contact area between the quenching water and the coke cake, thereby accelerating the quenching rate, shortening the quenching time by more than 1 / 2, and improving the utilization rate of the quenching car; at the same time, it also reduces the amount of quenching circulating water, which can correspondingly increase the output of the coking plant and reduce the power consumption of the quenching circulating water pump.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Embodiment 1:

[0025] As attached Figure 1 As shown, the present invention provides a new type of bottom plate for a horizontal heat recovery coke oven quenching car, including a coke receiving bottom plate 2 arranged in a coke receiving groove 1, the coke receiving bottom plate 2 is an arc-shaped structure bent downward in the width direction, and is a section of inferior arc when viewed from the end face of the coke receiving bottom plate 2. When the cubic coke block 3 is pushed forward on the coke receiving bottom plate 2, since the coke receiving bottom plate 2 is an arc-shaped structure bent downward, a part of the cubic coke block 3 is in a suspended state, and the suspended part of the cubic coke block 3 on the coke receiving bottom plate 2 breaks by itself under the action of gravity, thereby increasing the surface area of ​​the cubic coke block 3, increasing the contact area between the quenching water and the cubic coke block 3, and the quenching water can also flow into the center of the cubic coke block 3 along the gap, so that the whole cubic coke block 3 is fully cooled from the outside to the inside.

[0026] In this embodiment, the coke receiving bottom plate 2 is formed by splicing a plurality of folded plates in the width direction, and an inclined angle is set between the upper surfaces of each two adjacent folded plates, and an arc structure is formed by multiple sections of inclined folded plates. Such a setting allows the cubic coke block 3 to break at the bend between the two adjacent folded plates, thereby controlling the number and size of cracks generated in the coke cake after breaking.

[0027] In this embodiment, a rear baffle 101 and a front baffle 102 are provided on the coke receiving trough 1, and a movable baffle 103 is provided on the front baffle 102. The cubic coke block 3 enters the coke receiving trough 1 from the end thereof and moves on the coke receiving bottom plate 2. After the coke is sprayed and quenched in the coke quenching tower, the coke receiving trough 1 is tilted, so that the cubic coke block 3 is discharged from the movable baffle 103 to the coke drying platform.

[0028] Embodiment 2:

[0029] The present invention also provides a coke quenching method, which uses the above-mentioned novel bottom plate for a horizontal heat recovery coke oven quenching vehicle, and comprises the following steps:

[0030] The coke pushing device pushes the cubic coke block 3 into the coke receiving groove 1 from the end, and continuously moves forward on the coke receiving bottom plate 2.

[0031] like Figure 1 As shown, the portion indicated by the dotted line is the shape of the cubic coke block 3 before fracture. As the cubic coke block 3 continues to move, the suspended portion of the cubic coke block 3 on the coke receiving bottom plate 2 breaks by itself under the action of gravity until it breaks into several pieces. After the fracture, the cubic coke block 3 becomes pieces of coke cakes, thereby increasing the size of the surface area.

[0032] Finally, the broken cubic coke block 3 is transported by the quenching car to the quenching tower for water spray quenching. During the spraying and cooling, the quenching water flows into the inner center of the coke cake from the broken cracks, which increases the contact area between the quenching water and the coke cake, speeds up the quenching rate, shortens the quenching time by more than 1 / 2, and improves the utilization rate of the quenching car; at the same time, it also reduces the consumption of quenching circulating water, which can correspondingly increase the output of the coking plant and reduce the power consumption of the quenching circulating water pump.

[0033] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
