Technical Field

The invention relates to the field of ignition devices of coke oven carbonization chambers, in particular to an automatic interlocking ignition device for crude gas in an ascending pipe of a coke oven carbonization chamber.

Background

Coke oven pollution is characterized by intermittent emissions. During the coking production process, during the coal charging, coke pushing and coke quenching, the coke oven needs to discharge a large amount of unorganized smoke into the atmosphere, which can cause harm to human beings and the environment.

In the operation of opening the tube cover of the ascending tube before pushing coke (referred to as the "cover opening operation" for short), due to the existence of residual volatile components of coke and residual crude gas in the carbonization chamber, unorganized smoke can be inevitably discharged to the atmosphere, and the diffusion point of the unorganized smoke changes along with the change of the furnace number. The main components of the residual raw gas are C, H inorganic substances and a small amount of organic substances, and the pollution of the residual raw gas to the atmosphere can be greatly reduced by igniting and burning the residual raw gas. In the prior art, the capping operation and the ignition operation are generally manually performed, the riser pipe is capped, and then a torch is lifted to ignite the smoke discharged from the riser pipe.

The above operation has the disadvantage of high labor intensity, and may cause the escape of residual raw coke oven gas and the phenomenon of blasting. The blasting phenomenon is caused because the ascending pipe is higher in position, air is mixed into residual raw coke oven gas of the ascending pipe at the moment of opening a pipe cover of the ascending pipe, then a flame of a torch is ignited, and then deflagration can occur. The blasting phenomenon can cause the untight sealing and the leakage of the furnace body, and the residual raw coke oven gas is directly discharged through a chimney, thereby indirectly causing the environmental pollution.

Detailed Description

Referring to fig. 1, the automatic interlocking ignition device for crude gas in the ascending pipe of the coke oven carbonization chamber comprises an ascending pipe cover 1, an ignition gun 2 and a driver 3 for driving the ascending pipe cover to open and close; the ignition gun is rotatably arranged on the support at the top of the ascending pipe through a transmission device, and the transmission device is connected with the driver through a connecting rod mechanism. The ignition gun is installed on the ascending pipe cover support through a transmission device, vertical and horizontal rotary motion is formed along with opening and closing of the opening and closing cylinder, the ignition gun is vertical in a normal state, when the ascending pipe cover is opened and closed, the shifting rod connected to the extending shaft of the opening and closing cylinder drives the connecting rod and the turbine to move, the ignition gun portion makes circular motion towards the top opening of the ascending pipe, the vertical state is converted into the horizontal state, the ignition exciter is excited to ignite, the ignition time is 5-10 seconds, then reverse circular motion is performed, and the horizontal support is rapidly restored to be in the vertical state.

The link mechanism comprises a deflector rod sleeved on the driver extension shaft 18 and a link 20 connected with the other end of the deflector rod 19. The driver drives the extension shaft to move up and down and drives the connecting rod to move up and down through the deflector rod.

The transmission device 6 comprises a worm wheel 9 and a cam 10 arranged on the worm wheel; a long round hole-shaped guide groove (kidney-shaped hole) is formed in the cam, and a connecting shaft 13 in the center of the worm gear penetrates through the guide groove 12; the section of the connecting rod matched with the worm wheel is a worm section 11. Through the matching of the worm gear and the worm, when the worm reciprocates up and down, the worm gear rotates; the rotation of worm wheel drives rather than the cam rotation of being connected, and the rotation of cam drives the burning torch rotation on the one hand, and on the other hand because the bump protrusion of cam is along the limit outside the worm wheel consequently the guide way will drive the worm wheel outwards with the connecting axle cooperation when the bump of cam contacts with the worm to realize the reciprocating motion back and forth of burning torch. The worm wheel connecting rods are all arranged on the bracket 4 and can move up and down along with the deflector rod; the back of the cam above the guide groove is provided with a sliding block parallel to the guide groove, a sliding rail (or a sliding groove) matched with the sliding block is arranged at the position of the worm wheel corresponding to the sliding block, the sliding block is matched with the sliding rail to limit and support the cam, and the sliding rail and the sliding block are arranged in the same direction as the guide groove, so that the guide effect is better when the cam moves forwards and backwards by matching the sliding rail with the sliding block; the exposed end of the connecting shaft can be also provided with a limiting block for limiting the cam.

The ignition gun comprises an ignition head 5, an ignition circuit and an exciter. In the opening process of the ascending pipe cover, the ignition gun moves upwards along with the air cylinder and rotates, the ignition gun head rotates to the horizontal direction from the vertical direction and extends to the top of the ascending pipe, the exciter is triggered, and the residual raw coke oven gas is ignited by ignition. After ignition is finished, the ignition gun is quickly screwed back, and when the ascending pipe cover is closed, the ignition gun moves downwards along with the opening and closing cylinder to return to the original position, so that the ignition gun is far away from a fire source to prevent burning loss.

The drivers are interlockingly controlled by a central control room.

The driver is an ascending pipe cover opening and closing cylinder. The bracket 4 is fixed at the top of the ascending pipe and is linked with a deflector rod on an extension shaft of an opening and closing cylinder of the ascending pipe cover through a connecting rod, and the rotation of the ignition gun is linked with the ascending and descending of the opening and closing cylinder of the ascending pipe cover; all power supply and motion control are synchronously performed with a single-hole pressure regulating system 8 of a coke oven carbonization chamber, so that interlocking control is realized; the interlocking control specifically regulates the opening and closing of the ascending pipe cover and the movement and ignition control of the ignition gun through the instruction of the regulating system.

The body of the ignition gun is relatively provided with two protection components; the protection components comprise a driving wheel 14 arranged at the tail end of the gun body and a driven wheel 15 arranged at the front end of the gun body; the driving wheel is connected with the driven wheel through transmission chains, the two transmission chains are both provided with connecting rods 16, and a protection plate 17 is connected between the two connecting rods. The micro motor can be arranged at the end part of the ignition gun connected with the cam (the end part of the ignition gun can be arranged on the cam), the driving rod of the motor is connected with the driving wheel, and the connecting rod is controlled to do reciprocating motion at the front end of the driven wheel through the positive and negative rotation of the motor. The protective plate is indirectly driven to rotate by the movement of the transmission chain, so that the position of the protective plate can be adjusted to shield the nozzle of the ignition gun.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications and equivalent variations of the above embodiment according to the present invention are within the scope of the present invention.
