The present invention relates to an automatic ignition system for coke rising tubes using solar energy, and more particularly, to convert ignition by converting solar energy into electrical energy and igniting waste gas emitted from the COG gas generated in the coke process for producing coke. The present invention relates to a coke riser automatic ignition device using solar energy.

In general, as shown in the structure of the coke oven 11 shown in Figure 1 in the coke manufacturing process is to feed the raw coal to the coke oven 11 to be baked for a certain time, the quality gas generated in the coke baking process (COG) is recovered through a device called GCM (GAS COLLECTING MAIN) and reused as a heat source. However, at the completion of coke distillation, the line connected to G.C.M is cut off, the riser cover 14 is opened to release residual gas to the atmosphere, and coke secondary distillation is performed.

This secondary dry distillation process can be regarded as a process of depressing coke. When the riser tube cover 14 is opened, residual gas is discharged into the atmosphere, so that the discharge port of the riser 13 is ignited to prevent air pollution. Should give a ride.

In the conventional method of igniting the ascension pipe 13, the ignition was carried out by using a cylinder device on the tank for supplying raw coal in the upper part of the carbonization chamber. As a result of the ignition after the ignition, the gas leaks into the atmosphere, and there is a problem of being damaged by the collision between the ascending cover 14, which is already opened during the movement of the tank, and a mechanism that has not been recovered, and the upper part of the riser 13 immediately before ignition. The ignition device itself is burned or melted by the flame near 800 ℃ for several seconds before the cylinder is fully retracted after the ignition caused by tar and impurities emitted from the gas. Not doing.

Another conventional ignition method has been to ignite using a negative air pressure in the oven, which is a method of igniting using the positive atmospheric pressure outside the coke oven and the negative atmospheric pressure in the oven. Opening the rising pipe cover 14 and opening the raw coal injection port 15 opens a large amount of outside air into the carbonization chamber of negative pressure to escape to the rising pipe 13 at a high flow rate. At this time, the hot coke in the lower portion of the carbonization chamber (12) Most of the ignition is performed in this way because the powder (embers) is ignited as it explodes from the upper part of the ascending tube cover 14 as it rises up the upper part of the ascending tube 13 and no fire is required. The ignition method of the operator and the problem that the operator has to open the raw coal injection port 15 hassle with the mechanism and also most The main problem is that the upper air pollution of the coke is intensified due to the ignition in the state where a large amount of waste gas is discharged to the riser 13 by using a difference in air pressure, and a large amount of gas is already exposed in the air. Due to the ignition of the explosion tube 13 when the ignition is generated tremendous explosion sound and vibration. The reason why the explosion occurs in the above method is explained by the phenomenon that when a portable gas stove is ignited, a few ignition failures occur, and then a person tries to ignite a few more times and ignites with a popping sound. If the embers come into contact with the discharged state, an explosion will occur.

Explosive vibrations generated during ignition in the coke oven have a great effect on the fire bricks inside the oven, causing the cracks and breakage of the fire bricks to be intensified. 11) It is the life of its own. If the replacement of refractory bricks is necessary, it will cause enormous property damage and production disruption, such as rebuilding a coke plant. Although not to give a vibration there is a problem that the explosive vibration is generated in 15 ~ 17 / Hr cycle for the ignition of the riser (13). In the conventional method, since the gas is discharged for about 5 seconds after the riser cover 14 is opened and then ignited, the amount discharged from the riser 13 is insignificant. Since the amount of the riser tube 13 is about 600, since a large amount of gas is released as a whole, there is a problem that may affect air pollution.

Accordingly, the present invention has been made in view of the problems of the prior art, the purpose of which is to discharge the waste gas that must be discharged to the atmosphere of the COG gas generated in the process of producing coke, which is essential for the process of manufacturing iron ore from iron. It needs to be ignited in the ascending tube to attach it.The moment of opening of the ascending tube cover is calculated, the solar energy is turned on by using several stages of conversion circuit to calculate the opening angle of the cover and to ignite automatically to prevent the gas from leaking into the atmosphere. The present invention provides a coke riser automatic ignition device using solar energy that generates corona sparks to ignite COG gas.

In order to achieve the above object, the present invention is a solar cell for converting solar energy into electrical energy; A DC-AC converter which receives a DC voltage from the solar cell and converts the DC voltage into an AC voltage; A relay connected between the solar cell and the DC-AC converter to open and close a circuit; A booster for boosting the AC voltage of the DC-AC converter to a high voltage AC voltage; An AC-DC converter converting the high voltage AC voltage output from the boosting unit into a DC voltage; A high voltage high frequency conversion unit for receiving a high voltage DC voltage from the AC-DC converter and outputting a high voltage high frequency voltage; An ignition mounted at the outlet of the riser of the sintering machine to receive a high-voltage high-frequency voltage from the high-frequency high-frequency converter to cause corona discharge to ignite the gas discharged to the riser of the sintering machine; Ascending pipe cover closing means for detecting an opening and closing degree of the rising pipe cover mounted at the outlet of the rising pipe; When the waste gas is discharged by detecting the opening / closing degree of the rising pipe cover through the rising pipe cover opening / closing detecting means, the relay is driven to supply the DC voltage of the solar cell to the DC-AC converter to discharge the ignition. A control unit; It provides a coke rising tube automatic ignition device using solar energy, characterized in that it comprises a drive voltage generator for converting the AC voltage received from the DC-AC converter into a DC voltage to supply the driving voltage required for driving the controller. .

The ignition includes a base clamp fixed to one end of the riser; An outer housing detachably mounted to the base clamp; An inner housing mounted inside the housing; A pair of insulators fixed to the inner housing; It is fixed through the insulator and each end thereof is disposed toward the riser through a hole formed through the inner housing and the outer housing, and the other end is composed of ignition means connected to the high-voltage high-frequency converter through a connecting line.

The rising tube cover opening and closing detection means is an ultrasonic vibrator fixed to one end of the rising tube is generated by converting the signal provided from the control unit into ultrasonic waves; An ultrasonic reflector mounted to the riser cover to reflect ultrasonic waves generated from the ultrasonic vibrator; And an ultrasonic wave receiving means for receiving the ultrasonic waves reflected by the ultrasonic reflector, wherein the controller controls the phase difference between the ultrasonic wave generated through the ultrasonic vibrator and the reflected ultrasonic wave received through the ultrasonic wave receiving means. The degree of opening and closing of the riser cover is determined by the conversion recognition.

(Example)

Hereinafter, with reference to the accompanying drawings showing a preferred embodiment of the present invention described above in more detail.

In the present invention, in order to prevent the air leakage of gas to maintain a clean air environment in the vicinity of the coke plant 11, the riser cover 14, not the flow of ignition after the opening of the riser cover 14, is opened. In order to ignite at the point where the gas comes out, the movement of the cover 14 is calculated using ultrasonic waves, and the ignition timing is determined to ignite the gas at an angle at which leakage begins.

Tar and scale adhere between the pole and the pole 26 by a large amount of tar contained in the coke in the anode 26 of the ignition ignition 20, thereby causing a malfunction, which is caused by the COG gas coming up to the coke rising pipe 13. As a large amount of moisture, tar and fine dust, etc. are brought to the air together, a typical ignition method is because the tar and scale (SCALE) accumulate on both ends 26 where sparks occur, and both ends 26 are insulated. There is no spark inside.

For example, if the car ignition is not completely burned due to the problem of the car engine or the carburetor system, there is a case that the spark does not occur because the tar is insulated from the spark generating part of the ignition to insulate the anode. In order to cause a spark, if the material is buried in the anode, whether alternating or direct current, the material acts as an insulating material so that the spark does not occur.

In other words, air contains a large amount of moisture, which is not a perfect insulating fluid. When two metals with high voltage are placed in the air, electrons are moved through the air and sparks are generated.

By the way, if an insulator or the like is inserted between these two metals, sparks will not naturally occur.

However, in order to prevent a spark that contains a calorific value that can burn the insulator, it is necessary to penetrate the insulator to prevent the spark from occurring and to supply a strong heat source to the poles 26 at both ends of the ignition 20. In order to burn the tar between the two poles by high-frequency high-frequency high-frequency, and to prevent the ignition ignition 20 from being burned to the flame, the ignition ignition 20 structure with a double diaphragm is easily removable and removable. It will be described in detail with reference to the accompanying drawings to devise an ignition system having a base to reduce the exchange time as follows.
