Description

Technical Field

[0001] The invention discloses a wet coke quenching vehicle, which relates to the technical field of coke oven machinery in the coking industry, and in particular to a vehicle structure for wet coke quenching. Background Art

[0002] As one of the four major vehicles of coke oven machinery, the wet quenching car is used to receive the hot coke at about 1050℃ pushed out of the coke oven. After it is transferred to the bottom of the quenching tower, quenching water is sprayed from the opening above the coke box of the quenching car. The quenching water penetrates the hot coke while isolating the air and taking away the heat. Then, all the quenching water seeps into the parallel gutter of the overall inclined bottom plate and flows out directly from the bottom of the car door. The existing quenching form has the following main disadvantages:

[0003] 1. For the piled up coke, it is often the case that the top coke is completely extinguished, while the bottom coke is not completely extinguished, or even there is still hot coke. In case of last resort, secondary coke quenching is often required. This not only prolongs the quenching time, affects the coordinated operation cycle of the four major cars, reduces production efficiency, but also the moisture content of the secondary quenched coke is easy to exceed the standard, which directly affects the product quality of the coke.

[0004] 2. Waste of quenching water;

[0005] 3. Waste of energy.

[0006] In view of the problems existing in the above-mentioned prior art, it is very necessary to study and design a new type of wet quenching car to overcome the problems existing in the prior art. Summary of the invention

[0007] In view of the technical problems of the above-mentioned prior art, such as the coke pile is thick, the coke quenching is not complete, and secondary quenching is required, which reduces the production efficiency, wastes the quenching water, increases the water content of the coke, and affects the product quality, a wet quenching car is provided. The present invention mainly utilizes a new water trough structure to centrally introduce the quenching water to the bottom of the coke pile and flow it out in the reverse direction to quench the bottom of the coke pile, thereby achieving full quenching at one time, avoiding secondary quenching, and improving the quality of coke products and production efficiency.

[0008] The technical means adopted by the present invention are as follows:

[0009] A wet coke quenching car comprises: a car body, a coke quenching car and a coke quenching water nozzle, wherein the coke quenching car is arranged on the upper part of the car body; the coke quenching water nozzle is located on the upper part of the coke quenching car;

[0010] Furthermore, the quenching carriage is a bucket-shaped structure with an open top, which is composed of a front side wall, a door, a rear side wall, two left and right end walls and a bottom plate;

[0011] Further, the bottom plate is integrally inclined at an angle of approximately 28° with the horizontal plane. Its higher end is connected to the rear side wall, and its lower end is fixed to one side of the vehicle body below the front side wall, beyond the door at the bottom of the front side wall.

[0012] Further, the bottom plate includes: a bottom plate lining and a bottom plate frame; several inclined drain troughs, straight drain troughs, and two collecting troughs are arranged on the bottom plate frame for the flow and convergence of quenching water.

[0013] Further, an intermediate wall perpendicular to both of them is provided between the middle part of the bottom plate and the front side wall, which is used to reinforce the strength of both and disperse the effect of the hot coke pile.

[0014] Further, the upper surface of the bottom plate frame is covered with a grid-shaped bottom plate lining, and a narrow gap is left between each bottom plate lining for the quenching water to seep into the drain troughs of the bottom plate frame.

[0015] Further, the drain troughs include: inclined drain troughs, straight drain troughs, and collecting troughs.

[0016] Further, the inclined drain troughs are arranged in a radial and inclined manner. Its starting end is located at the higher end of the bottom plate, and the end is inclined and concentrated towards the middle and lower parts of the bottom plate, forming an inverted triangular inclined drain trough area in the upper and middle parts of the bottom plate, and finally flowing into the two collecting troughs in the middle of the bottom plate.

[0017] Further, the straight drain troughs are all arranged along the direction from high to low parallel to the two side surfaces of the intermediate wall.

[0018] Further, the collecting troughs are arranged in parallel along the two side surfaces of the intermediate wall from high to low.

[0019] Further, the bottom plate lining includes: a return port lining and a conventional lining.

[0020] Further, the return port lining is a locally thickened structure with an open mouth, and as a part of the return port, it is located in the middle and lower part of the bottom plate area.

[0021] Further, the conventional lining is a uniformly thin structure, which is used to cover most of the area of the upper surface of the bottom plate frame except for the two return ports.

[0022] Further, at the end of the collecting trough, which is in the thicker part of the coke pile, a return port is provided.

[0023] Further, the return port includes: a guide plate and a return port lining.

[0024] Further, the higher end of the guide plate is connected to the bottom of the end of the collecting trough, and the lower end is the lower edge of the return port, which is used to lead the quenching water in the collecting trough out of the return port.

[0025] Further, the reflux port liner covers above the deflector plate, forming a downward-facing opening with the deflector plate, which is the reflux port. The quenching water in the water collecting tank can gush out from the reflux port and enter the parts of the coke pile that are most difficult to be thoroughly quenched, on both sides of the bottom of the middle wall, approximately in the area slightly below the center of the bottom plate.

[0026] The quenching method of the present invention is as follows:

[0027] When the quenching car is transported under the quenching tower, the quenching water is sprayed from the quenching water nozzles at the upper opening of the coke box of the quenching car. While passing through the hot coke pile and isolating it from the air, the heat of the coke is taken away. Then, a part of the quenching water enters the straight-flow water tank and directly flows out from the lower end of the bottom plate. Another part flows along the concentrated inclined flow water tank from a higher position of the bottom plate, gathers in the water collecting tank in the middle of the bottom plate, and is sprayed out again from the reflux port, directly spraying from the bottom on the area where the coke is piled up thickest. The quenching water returned in this way finally returns to the straight-flow water tank of the bottom plate and also directly flows out from under the bottom plate.

[0028] Compared with the prior art, the present invention has the following advantages:

[0029] 1. The wet quenching car provided by the present invention realizes the automatic reflux and reuse of the primary quenching water. Both the reflux water and the spraying water are automatically completed during the primary quenching process, shortening the total quenching time, improving the quenching efficiency and the quality of the coke product;

[0030] 2. The wet quenching car provided by the present invention repeatedly uses the reflux cooling water, saving the consumption of quenching water;

[0031] 3. The wet quenching car provided by the present invention does not require an additional power mechanism, saving energy;

[0032] 4. The wet quenching car provided by the present invention has a simple structure, does not require high manufacturing precision, is durable, and hardly increases the manufacturing cost.

[0033] In summary, applying the technical solution of the present invention solves the problems in the prior art such as a relatively thick coke pile, incomplete quenching, the need for secondary quenching, reducing production efficiency, wasting quenching water, increasing the water content of coke, and affecting product quality.
