Description

Technical Field

[0001] This utility model relates to the field of venting pipe technology, and in particular to an automatic ignition device for coke oven venting pipe. Background Technology

[0002] The coke oven vent pipe is an important device used in the coking process to discharge excess coal gas. During the coke oven gas production process, when the gas blower cannot properly discharge the raw coal gas, the excess coal gas is discharged into the atmosphere through the vent pipe. In order to reduce environmental pollution, most of the harmful substances in the raw coal gas are usually burned off by ignition.

[0003] The existing ignition devices for coke oven vent pipes are mainly exposed at the vent pipe opening and cannot be retracted. After prolonged use, they are prone to damage due to high temperatures, and the igniter is easily covered by tar, leading to ignition failure. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing coke oven vent pipe ignition devices, which cannot be retracted, and to propose an automatic ignition device for coke oven vent pipes.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An automatic ignition device for a coke oven vent pipe includes a vent pipe body and a processor. An air inlet pipe is fixedly connected to the bottom of one side of the vent pipe body, and an air valve is provided on the air inlet pipe. An ignition port is provided on one side of the vent pipe body. An installation box is fixedly connected to the outer wall of one side of the vent pipe body. A first electric push rod is fixedly connected to the inner wall of one end of the installation box. An igniter is fixedly connected to one end of the first electric push rod. The ignition needle of the igniter can extend into the vent pipe body from the ignition port. A second electric push rod is fixedly connected to the outer wall of one side of the vent pipe body. A sealing plate is fixedly connected to the top of the second electric push rod, and the sealing plate blocks one side of the ignition port. A gas detector is inserted into one side of the vent pipe body, and a flame detector is inserted into the other side of the vent pipe body.

[0007] Furthermore, the ignition head of the igniter is fitted with an isolation plate.

[0008] Furthermore, a support frame is fixedly connected to the outer circumferential wall of the vent pipe body.

[0009] Furthermore, a rain cover is fixedly connected to the top of the vent pipe body.

[0010] Furthermore, a first high-temperature resistant plate is bonded to the inner wall of the vent pipe body.

[0011] Furthermore, a sealing ring is fitted onto the outer wall of the sealing plate.

[0012] Furthermore, a second high-temperature resistant plate is adhered to one side of the sealing plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By moving the igniter with the first electric push rod, the igniter is retracted into the mounting box, thereby preventing high temperature from damaging the igniter.

[0015] 2. By moving the sealing plate upward under the action of the second electric push rod, the sealing plate is blocked on one side of the ignition port, thereby preventing the flame from entering the mounting box. Attached Figure Description

Detailed Implementation

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Reference Figure 1-Figure 3An automatic ignition device for a coke oven vent pipe includes a vent pipe body 1 and a processor. An air inlet pipe 2 is welded to the bottom of one side of the vent pipe body 1, and an air valve 11 is installed on the air inlet pipe 2. An ignition port is located on one side of the vent pipe body 1. A mounting box 3 is bolted to the outer wall of one side of the vent pipe body 1. A first electric push rod 4 is bolted to the inner wall of one end of the mounting box 3. An igniter 5 is bolted to one end of the first electric push rod 4. The ignition needle of the igniter 5 can extend into the vent pipe body 1 from the ignition port. The first electric push rod 4... The igniter 5 is moved so that it is retracted into the mounting box 3. A second electric push rod 7 is fixed to one side of the outer wall of the vent pipe body 1 by bolts. A sealing plate 8 is fixed to the top of the second electric push rod 7 by bolts. Under the action of the second electric push rod 7, the sealing plate 8 moves upward, thereby blocking the sealing plate 8 on one side of the ignition port, thus preventing the flame from entering the mounting box 3. A gas detector 9 is inserted into one side of the vent pipe body 1, and a flame detector 10 is inserted into the other side of the vent pipe body 1.

[0022] Ignition head of igniter 5 is fitted with isolation plate 6 to isolate igniter 5 and first electric push rod 4, thereby preventing flame from damaging igniter 5 and first electric push rod 4. Support frame 12 is fixed to the outer circumference of vent pipe body 1 by bolts to support vent pipe body 1. Rain cover 13 is fixed to the top of vent pipe body 1 by bolts to prevent rainwater from falling into vent pipe body 1. First high temperature resistant plate 14 is bonded to the inner wall of vent pipe body 1 to improve the high temperature resistance of vent pipe body 1. Sealing ring 15 is fitted to the outer wall of sealing plate 8. Second high temperature resistant plate 16 is bonded to one side of sealing plate 8. Processor is electrically connected to first electric push rod 4, second electric push rod 7, gas detector 9 and flame detector 10.

[0023] Working principle: In use, firstly, the gas valve 11 is opened, and the gas enters the vent pipe body 1 from the gas inlet pipe 2. When the gas detector 9 detects the gas in the vent pipe body 1, it transmits the information to the processor. Then, the processor controls the second electric push rod 7 to move the sealing plate 8 downward, thereby opening the ignition port. Next, the processor controls the first electric push rod 4 to move the igniter 5, thereby extending the ignition needle of the igniter 5 from the ignition port into the vent pipe body 1, and then igniting through the igniter 5. When the flame detector 10 detects a moving flame, it transmits the information to the processor. Then, the processor controls the first electric push rod 4 to retract the igniter 5 into the mounting box 3. Next, the processor controls the second electric push rod 7 to block the sealing plate 8 on one side of the ignition port, thereby preventing the flame from entering the mounting box 3.

[0024] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
