To the technical defect, the utility model provides a coke oven tedge ignition can ignite the raw coke oven gas when uncapping, through lighting it the burning, can reduce its pollution to atmosphere by a wide margin.
In order to achieve the technical purpose, the utility model discloses a following technical scheme realizes:
a coke oven ascending pipe ignition device comprises an ascending pipe body, wherein a ascending pipe cover is installed at the opening position of the top of the ascending pipe body, and a pull rod is arranged on the ascending pipe cover; the ignition device comprises an ignition rod positioned right above the ascending pipe cover; the ignition rod is fixedly connected with the support ascending pipe body; the ignition rod is connected with a switch positioned on the outer side of the ascending pipe body through a cable.
Preferably: the ignition rod is a high-temperature ceramic ignition needle.
Preferably: a rain cover is arranged above the ignition rod.
Preferably: the switch is fixed on the outer wall of the ascending pipe body.
The utility model has the advantages and the technical effect be:
the utility model discloses can light combustible gas in the twinkling of an eye after the tedge is covered, can light the diffuse gas in the twinkling of an eye when the tedge diffuses at the discharge pressure risees suddenly, avoided the environmental protection accident, the utility model has the advantages of simple structure, convenient operation.

FIG. 1 is a block diagram of a preferred embodiment of the present invention;
wherein: 1. a riser body; 2. a switch; 3. a support; 4. an ignition bar; 5. a riser cover; 6. a cable; 7. a pull rod.
Detailed Description
In order to make the above objects, control system and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
Referring to fig. 1, the ignition device for the ascending pipe of the coke oven comprises a ascending pipe body 1, wherein a ascending pipe cover 5 is installed at the top opening position of the ascending pipe body 1, and a pull rod 7 is arranged on the ascending pipe cover 5; the ignition device comprises an ignition rod 4 positioned right above the riser cover 5; the ignition rod 4 is fixedly connected with the ascending pipe body 1 through a support 3; the ignition rod 4 is connected with the switch 2 positioned outside the ascending pipe body 1 through a cable 6. In the preferred embodiment: the ignition rod 4 is a high-temperature ceramic ignition needle. A rainproof cover is arranged above the ignition rod 4. The switch 2 is fixed on the outer wall of the ascending pipe body 1.
The preferred embodiment mainly comprises a high-temperature ceramic ignition needle, a bracket, a cable, a switch and the like, and the device can directly ignite residual raw coke oven gas released by the riser by using the high-temperature ceramic ignition needle. The device is characterized in that a switch is arranged at a position two meters high on the outer wall of the ascending pipe body. The ignition rod is arranged in the positive direction of the cover opening position of the ascending pipe cover. During normal operation, the lower switch of the igniter is pressed, the ascending pipe turning plate is closed, and the ascending pipe cover is opened. The ignition rod adopts a high-temperature ceramic technology, is immediately red-hot after being electrified, and has high reliability. The igniter power supply cable meets the requirements of flame retardance, water resistance, corrosion resistance and high temperature resistance. The device connecting fastener, the bracket and the like are made of stainless steel materials and need to be resistant to corrosion and high temperature. The switch, the button and the circuit are made of high-temperature resistant products. And a rain cover is required to be arranged on the upper part of the ignition rod.
A set of crude gas ignition device with a cover is arranged on each ascending pipe. A switch is arranged at a position of two meters on the outer wall of the ascending pipe barrel and is connected with a top ignition rod and a support through a cable, and the ignition rod is arranged in the opposite direction of the uncovering position of the ascending pipe cover.
During normal operation, the lower switch of the igniter is pressed, the ascending pipe turning plate is closed, the ascending pipe cover is opened, and the red hot ignition rod after being electrified is directly connected with the ascending pipe cover to burn the residual raw coke oven gas.
The working principle is as follows:
the operator presses the coke pushing plan, firstly presses the igniter switch, closes the ascending pipe turning plate, opens the ascending pipe cover, and instantly ignites the residual raw coke gas after meeting the ignition rod. The device has high ignition efficiency, and the igniter can realize the condition that the ignition rod ignites gas at high temperature within 2-3 seconds after receiving the switching signal.
The ignition device needs to have the following requirements: the ignition rod adopts a high-temperature ceramic technology, is immediately red-hot after being electrified, has high reliability, and directly ignites the raw coke oven gas to be discharged. The igniter power supply cable is connected to meet the requirements of flame retardance, water resistance, corrosion resistance and high temperature resistance; connecting fasteners, brackets and the like are made of stainless steel materials and need to be resistant to corrosion and high temperature.
The switch, the button and the circuit are made of high-temperature-resistant products, and the installation position is two meters under the outer wall of the ascending pipe, so that the button can be conveniently operated by an operator. Considering the influence on the ignition rod in the rainfall, the upper part of the ignition rod needs to be provided with a rain cover.
In addition, after the pressure of the gas collecting pipe is suddenly increased, the riser cover is pushed open to release raw coke oven gas, a switch can be directly started to be directly ignited, and environmental accidents are avoided.
The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
