Description

Technical field:

[0001] The utility model belongs to the field of coal coking production, and in particular relates to a coke quenching spray device. Background technology:

[0002] Coal is converted into coke through high-temperature dry distillation. This process is called coking. The coking process is carried out in a coke oven. The coke produced is mainly used in metallurgy. When the coke comes out of the oven, the temperature of the coke is generally 950℃-1100℃. In order to facilitate calculation and storage, the high-temperature coke must be cooled to below 250℃. This cooling process is called quenching. The cooled coke is sent to the blast furnace to smelt steel.

[0003] The existing process generally adopts wet quenching, that is, the quenching car transports the high-temperature coke to the quenching tower, and the quenching tower directly uses spray water to sprinkle on the high-temperature coke to cool it down. The large amount of steam generated during the quenching process emerges from the top of the quenching tower. In this process, since the spray water pipe is mainly fixed at the top center of the quenching tower, the spray water is mainly sprinkled on the coke core (top of the slope), while the outermost edge of the coke pile (bottom of the slope) cannot be sprinkled in time, which is prone to red coke, resulting in an overall worse quenching effect; secondly, after the coke is poured into the quenching car, it will gradually pile up into a mountain, while the diameters of multiple spray pipes in the existing quenching tower are the same, and the amount of water sprayed at the same time is also the same, so that the amount of water sprayed on the top of the coke pile and the half-slope of the coke is the same, resulting in the water content at the half-slope of the coke being much greater than the water at the top of the pile, resulting in uneven water content at various positions of the coke pile, longer quenching time, a large increase in quenching water consumption, and waste of water resources. Utility model content:

[0004] The utility model aims to provide a coke quenching spray device, and overcomes the shortcomings of the above-mentioned prior art, and effectively solves the existing problem of uneven coke quenching spray.

[0005] Contents of the utility model: A coke quenching spray device comprises a frame-shaped spray pipe, a first nozzle is installed on the frame-shaped spray pipe, a main spray pipe is spanned in the frame of the frame-shaped spray pipe, both ends of the main spray pipe are connected to the frame-shaped spray pipe, a second nozzle is installed on the main spray pipe, and a water inlet pipe is connected to the main spray pipe.

[0006] Furthermore, auxiliary spray pipes are arranged in the same direction on both sides of the main spray pipe, the main spray pipe and the auxiliary spray pipe are connected through a branch pipe, and a third nozzle is installed on the auxiliary spray pipe.

[0007] Furthermore, the pipe diameters of the main spray pipe, the auxiliary spray pipe and the frame-shaped spray pipe decrease in sequence.

[0009] Furthermore, the first nozzle, the second nozzle and the third nozzle are all fan-shaped nozzles.

[0010] Furthermore, the aperture sizes of the second nozzle, the third nozzle and the first nozzle decrease in sequence.

[0011] Furthermore, both ends of the auxiliary spray pipe are connected to the frame-shaped spray pipe.

[0012] The beneficial effects of the utility model are as follows: the outermost edge of the coke pile can be sprayed in time through the frame-shaped spray pipe, thereby preventing the occurrence of red coke; the water spraying volume of each spray pipe is changed so that the amount of spraying water received by each position of the coke pile can be uniform, thereby improving the coke quenching effect, reducing the coke quenching time and water consumption, and avoiding the waste of water resources.

[0015] In the figure: 1 frame-shaped spray pipe, 2 first nozzle, 3 main spray pipe, 4 second nozzle, 5 water inlet pipe, 6 auxiliary spray pipe, 7 branch pipe, 8 third nozzle. Specific implementation method:

[0016] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation of the present invention is now described with reference to the accompanying drawings:

[0017] like Figure 1 to Figure 2 As shown, a quenching spray device comprises a frame-shaped spray pipe 1, a first nozzle 2 is installed on the frame-shaped spray pipe 1, a main spray pipe 3 is spanned in the frame of the frame-shaped spray pipe 1, both ends of the main spray pipe 3 are connected to the frame-shaped spray pipe 1, a second nozzle 4 is installed on the main spray pipe 3, a water inlet pipe 5 is connected to the main spray pipe 3, auxiliary spray pipes 6 are arranged in the same direction on both sides of the main spray pipe 3, the main spray pipe 3 and the auxiliary spray pipe 6 are connected by a branch pipe 7, and a third nozzle 8 is installed on the auxiliary spray pipe 6.

[0018] Specifically, the outermost edge of the coke pile can be sprayed in time through the frame-shaped spray pipe 1, thereby preventing the occurrence of red coke.

[0019] During actual use, the coke is discharged from the furnace and poured into the coke oven car, and the coke oven car drives under the coke quenching tower. At this time, the external water source is injected into the main spray pipe 3, and the second nozzle 4 sprays water on the top of the coke pile; after the water in the main spray pipe 3 flows into the frame-shaped spray pipe 1, the frame-shaped spray pipe 1 with the same shape as the top of the coke oven car sprays water to the outermost edge of the coke pile through the first nozzle 2; the water flow in the main spray pipe 3 flows into the auxiliary spray pipe 6 through the branch pipe 7, and the third nozzle 8 sprays water on the half slope of the coke pile.

[0020] like Figure 1 to Figure 2 As shown, a coke quenching spray device, the pipe diameter sizes between the main spray pipe 3, the auxiliary spray pipe 6 and the frame-shaped spray pipe 1 are reduced in sequence, a plurality of the first nozzles 2 are evenly installed on the bottom wall of the frame-shaped spray pipe 1 along the length direction, a plurality of the second nozzles 4 are evenly installed on the bottom wall of the main spray pipe 3 along the length direction, a plurality of the third nozzles 8 are evenly installed on the bottom wall of the auxiliary spray pipe 6 along the length direction, the first nozzle 2, the second nozzle 4 and the third nozzle 8 are all fan-shaped nozzles, the aperture sizes of the second nozzle 4, the third nozzle 8 and the first nozzle 2 are reduced in sequence, and both ends of the auxiliary spray pipe 6 are connected to the frame-shaped spray pipe 1.

[0021] Specifically, by changing the diameters of the main spray pipe 3, the auxiliary spray pipe 6 and the frame-shaped spray pipe 1, the amount of spray water received by each position of the coke pile can be uniform, thereby improving the coke quenching effect.

[0022] In actual use, as the height of the coke pile gradually decreases, the amount of spray water received at the top of the coke pile, the mid-slope of the coke pile, and the bottom of the coke slope will also decrease accordingly, and the pipe diameters of the main spray pipe 3, the auxiliary spray pipe 6, and the frame spray pipe 1 will decrease successively, and the apertures of the second nozzle 4, the third nozzle 8, and the first nozzle 2 will decrease successively, so that the amount of water sprayed at the top of the coke pile, the mid-slope of the coke pile, and the bottom of the coke slope will also decrease successively, so that the amount of spray water at each position of the coke pile is appropriate, which not only reduces the time for quenching coke, but also reduces the amount of water used for quenching coke, avoiding waste of water resources;

[0023] The evenly installed first nozzles 2, second nozzles 4 and third nozzles 8 can spray water evenly on the coke pile; the fan-shaped nozzles make the spraying coverage wider, further improving the coke quenching effect.

[0024] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
