Description

Technical Field

[0001] This utility model relates to the field of coke oven combustion chamber gas supply technology, specifically to a segmented gas supply heating device for coke oven combustion chamber. Background Technology

[0002] The segmented gas supply heating device for coke oven combustion chambers is an advanced coke oven heating technology that achieves efficient heating of the combustion chamber through segmented gas supply. This device divides the combustion chamber into multiple zones, each supplied with gas independently, ensuring uniform combustion of fuel and improving thermal efficiency. Simultaneously, precise control of the gas supply volume and timing allows for accurate temperature control of the coke oven, ensuring stable coke quality. Furthermore, this device helps reduce nitrogen oxide emissions, improving environmental performance.

[0003] However, the traditional segmented gas supply heating device for coke oven combustion chamber needs improvement in the mixing of air and combustible gas. This is mainly because the air and combustible gas are not mixed evenly when directly injected into the combustion chamber. Uneven mixing may lead to incomplete local combustion, resulting in the emission of harmful gases, and may even cause safety accidents such as explosions. Therefore, a segmented gas supply heating device for coke oven combustion chamber is proposed. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the air and combustible gas are not mixed evenly when the traditional segmented gas supply heating device for coke oven combustion chamber is directly injected into the combustion chamber. This invention provides a segmented gas supply heating device for coke oven combustion chamber.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution: A segmented gas supply and heating device for a coke oven combustion chamber includes a coke oven. The coke oven has several horizontally equidistant carbonization chambers and several horizontally equidistant combustion chambers, each located between two adjacent carbonization chambers. A gas chamber is located to the lower left of each combustion chamber, and an air chamber is located to the lower right of each combustion chamber. A channel penetrating the coke oven is opened directly below each combustion chamber. A mixing mechanism for mixing air and combustible gas is installed inside each channel. Below each mixing mechanism are two mirror-image pipes (I), each pair of adjacent pipes (I) connecting to the adjacent gas chamber and air chamber, respectively. Above each mixing mechanism is a pipe (II), each pipe (II) connecting to the interior of the combustion chamber directly above it. An airflow mechanism for driving the mixing mechanism to rotate is located at the back of the coke oven. A detection mechanism for detecting gas leaks is installed inside each channel.

[0006] Furthermore, the mixing mechanism includes cylinders, each channel has a cylinder inside, each cylinder has an annular groove at its upper and lower edges, each annular groove has a movably installed ring inside, each ring has a fixedly installed cover plate inside, each pipe two is fixedly connected to the adjacent cover plate, each pipe two is connected to the interior of the adjacent cylinder, each pipe one is fixedly connected to the adjacent cover plate, and each pipe one is connected to the interior of the adjacent cylinder.

[0007] Furthermore, the mixing mechanism also includes a flow divider, with a flow divider fixedly installed inside the first output end of each pipe and a flow divider fixedly installed inside the second output end of each pipe.

[0008] Furthermore, the airflow mechanism includes an air supply pipe, which is fixedly installed on the back of the coking oven. A high-pressure nozzle is fixedly installed on the air supply pipe at the position corresponding to each channel, and several evenly distributed fan blades are fixedly installed on the outer wall of each cylinder.

[0009] Furthermore, the detection mechanism includes a chute, with chute openings on the left and right sides of each channel. Each channel has a crossbar inside, with both ends of each crossbar movably installed inside the adjacent chute. A square tube is fixedly installed on the top of each crossbar, and a gas detector is placed inside each square tube.

[0010] Furthermore, the detection mechanism also includes round rods, with a round rod fixedly installed on the side of each crossbar away from the mixing mechanism, and a crossbar two fixedly installed at the end of each round rod away from the crossbar one. Rotatable rotating rods are movably installed on both sides of the front wall of the coking oven via damping shafts.

[0011] The beneficial effects of this utility model are as follows: This invention first feeds prepared coal into the carbonization chamber via a coal charging device. Simultaneously, the gas chamber and air chamber inject combustible gas (such as coal gas) and air into the combustion chamber, respectively. The combustible mixture is ignited by an ignition device in the combustion chamber, initiating a combustion reaction. At this time, the coal inside the carbonization chamber undergoes a series of chemical reactions such as drying, pyrolysis, melting, bonding, and solidification at high temperatures, gradually forming coke. During the process of injecting combustible mixture into the combustion chamber from the gas chamber and air chamber, combustible gas and air are injected into the mixing mechanism through corresponding pipes. At the same time, the airflow mechanism is activated, causing each mixing mechanism to rotate. The combustible gas and air inside each mixing mechanism will mix under the action of centrifugal force. The combustible mixture discharged from the mixing mechanism enters the combustion chamber through pipe two for combustion. Since the combustible gas and air are fully mixed inside the mixing mechanism, they can achieve complete combustion. In addition, each detection mechanism can detect potential gas leaks in real time, ensuring the safety of the production process. Attached Figure Description

[0017] like Figures 1 to 4As shown, a segmented gas supply heating device for a coke oven combustion chamber includes a coke oven 1. The coke oven 1 has several transversely equidistantly distributed carbonization chambers 2 and several transversely equidistantly distributed combustion chambers 3, each combustion chamber 3 located between two adjacent carbonization chambers 2. A gas chamber 4 is located to the lower left of each combustion chamber 3 inside the coke oven 1, and an air chamber 5 is located to the lower right of each combustion chamber 3 inside the coke oven 1. A channel 6 penetrating the coke oven 1 is opened directly below each combustion chamber 3. The interior of each channel 6... Each coke oven 1 is equipped with a mixing mechanism 8 for mixing air and combustible gas. Below each mixing mechanism 8 are two mirror-distributed pipes 7, each pair of adjacent pipes 7 connecting to the adjacent gas chamber 4 and air chamber 5, respectively. Above each mixing mechanism 8 is a pipe 9, each pipe 9 connecting to the interior of the combustion chamber 3 directly above. At the back of the coke oven 1 is an airflow mechanism 10 for driving the mixing mechanism 8 to rotate. Inside each channel 6 is a detection mechanism 11 for detecting gas leaks. It should be noted that... The prepared coal is fed into the carbonization chamber 2 via a coal charging device. Simultaneously, the gas chamber 4 and air chamber 5 inject combustible gas (such as coal gas) and air into the combustion chamber 3, respectively. The combustible mixture is ignited by an ignition device within the combustion chamber 3, initiating a combustion reaction. At this time, the coal inside the carbonization chamber 2 undergoes a series of chemical reactions at high temperatures, including drying, pyrolysis, melting, bonding, and solidification, gradually forming coke. During the process of injecting the combustible mixture into the combustion chamber 3 via the gas chamber 4 and air chamber 5, the gas chamber 4 and air chamber 5 respectively supply the mixing mechanism through corresponding pipes 7. Combustible gas and air are injected into the interior of mixing mechanism 8, and the airflow mechanism 10 is activated. The airflow mechanism 10 is used to rotate each mixing mechanism 8. The combustible gas and air inside each mixing mechanism 8 will be mixed under the action of centrifugal force. The combustible mixture discharged from the mixing mechanism 8 enters the combustion chamber 3 through pipe 2 9 for combustion. Since the combustible gas and air are fully mixed inside the mixing mechanism 8, they can be fully combusted. In addition, each detection mechanism 11 can detect potential gas leaks in real time to ensure the safety of the production process.

[0018] The mixing mechanism 8 includes a cylinder 801. Each channel 6 has a cylinder 801 inside. Each cylinder 801 has an annular groove 802 at both its upper and lower edges on its inner wall. A ring 803 is movably installed inside each annular groove 802. A cover plate 804 is fixedly installed inside each ring 803. Each pipe 9 is fixedly connected to an adjacent cover plate 804 and communicates with the interior of an adjacent cylinder 801. Each pipe 7 is fixedly connected to an adjacent cover plate 804. It is connected to the interior of the adjacent cylinder 801. It should be noted that the gas chamber 4 and the air chamber 5 inject combustible gas and air into the interior of the cylinder 801 through the corresponding pipe 7. When the airflow mechanism 10 is used to rotate each mixing mechanism 8, each cylinder 801 will rotate under the action of the airflow mechanism 10. At this time, the combustible gas and air inside the cylinder 801 will be mixed under the action of centrifugal force. The combined action of the annular groove 802 and the ring 803 can effectively limit the cylinder 801 to rotate stably.

[0019] The mixing mechanism 8 also includes a diversion net 805. A diversion net 805 is fixedly installed inside the output end of each pipe 1 7 and a diversion net 805 is fixedly installed inside the output end of each pipe 2 9. It should be noted that the diversion net 805 located inside the pipe 1 7 can further disperse the combustible gas or air, further improving the fusion effect of combustible gas and air inside the cylinder 801. The diversion net 805 located inside the pipe 2 9 can further disperse the combustible mixture when it is output, so that the combustible mixture can be fully combusted.

[0020] The airflow mechanism 10 includes an air supply pipe 1001. The air supply pipe 1001 is fixedly installed on the back of the coke oven 1 (the input end of the air supply pipe 1001 in this technical solution is connected to the air supply equipment. Since the air supply equipment is existing technology, it will not be described in detail here). A high-pressure nozzle 1002 is fixedly installed on the air supply pipe 1001 at the position corresponding to each channel 6. Several evenly distributed fan blades 1003 are fixedly installed on the outer wall of each cylinder 801. It should be noted that when the air supply equipment is turned on and the airflow is discharged through the air supply pipe 1001 and the high-pressure nozzle 1002, each high-pressure nozzle 1002 discharges a high-speed airflow. Since several evenly distributed fan blades 1003 are fixedly installed on the outer wall of each cylinder 801, when the high-speed airflow blows to the fan blades 1003, it can drive the cylinder 801 to rotate. The rotation of the cylinder 801 can mix the combustible gas and air inside.

[0021] The detection mechanism 11 includes a chute 1101. Each channel 6 has a chute 1101 on both the left and right sides. Each channel 6 has a crossbar 1102 inside. The two ends of each crossbar 1102 are movably installed inside the adjacent chute 1101. A square tube 1103 is fixedly installed on the top of each crossbar 1102. A gas detector 1104 is placed inside each square tube 1103. It should be noted that each gas detector 1104 can detect the gas around the adjacent mixing mechanism 8 in real time, thereby determining whether there is a flammable gas leak, ensuring the safety of the production process. Each gas detector 1104 can be removed from the corresponding square tube 1103 for easy maintenance. When removing the gas detector 1104, the crossbar 1102 can be pulled to move the two ends of the crossbar 1102 away from the mixing mechanism 8 inside the corresponding chute 1101.

[0022] The detection mechanism 11 also includes round rods 1105. A round rod 1105 is fixedly installed on the side of each crossbar 1102 away from the mixing mechanism 8. A crossbar 2 1106 is fixedly installed at the end of each round rod 1105 away from the crossbar 1102. Rotatable rotating rods 1107 are movably installed on both sides of the front wall of the coking oven 1 via damping shafts on each channel 6. It should be noted that when pulling the crossbar 1102, the corresponding two rotating rods 1107 must first be rotated so that each... Rotating rod 1107 can be rotated to a horizontal position. Then, pull the second crossbar 1106. The second crossbar 1106 drives the corresponding round rod 1105, and the round rod 1105 drives the corresponding first crossbar 1102 to complete the purpose of pulling the first crossbar 1102. In order to avoid the first crossbar 1102 from displacement during normal detection, when the first crossbar 1102 is closest to the mixing mechanism 8, rotate the two corresponding rotating rods 1107 to reset. Use the rotating rods 1107 to prevent the second crossbar 1106 from moving.

[0023] In summary: First, the prepared coal is fed into the carbonization chamber 2 through the coal charging equipment. Simultaneously, the gas chamber 4 and air chamber 5 inject combustible gas (such as coal gas) and air into the combustion chamber 3, respectively. The combustible mixture is ignited by the ignition device in the combustion chamber 3, initiating the combustion reaction. At this time, the coal inside the carbonization chamber 2 undergoes a series of chemical reactions at high temperature, including drying, pyrolysis, melting, bonding, and solidification, gradually forming coke. During the process of injecting the combustible mixture into the combustion chamber 3 from the gas chamber 4 and air chamber 5, the gas chamber 4 and air chamber 5 respectively supply the mixture to the mixer through corresponding pipes 7. Combustible gas and air are injected into the interior of the mixing mechanism 8, and the airflow mechanism 10 is activated. The airflow mechanism 10 is used to rotate each mixing mechanism 8, and the combustible gas and air inside each mixing mechanism 8 will be mixed under the action of centrifugal force. The combustible mixture discharged from the mixing mechanism 8 enters the combustion chamber 3 through the pipe 2 9 for combustion. Since the combustible gas and air are fully mixed inside the mixing mechanism 8, they can be fully combusted. In addition, each detection mechanism 11 can detect potential gas leaks in real time to ensure the safety of the production process.
