The fire extinguisher 100 has an internal space into which the fire extinguisher 10 can be charged and a plurality of nozzles connected to the refrigerant supply line 200 are installed at an upper portion thereof. The hot glow coke (C) is extinguished by the coolant sprayed from each of the plurality of nozzles.

Each of the refrigerant supply line 200 and the recovery line 800 may be in the form of a pipe having an internal space so that the refrigerant can pass or flow.

The drainage passage 400 has an inner space for allowing the refrigerant to flow, and one end of the drainage passage 400 is connected to the digester 100 and extends in a direction in which the sedimentation source 600 is located.

The sedimentation paper 600 may have a tubular shape having an inner space and an open upper side.

The rotating device 500 is installed on the path of the refrigerant of the drainage passage 400 to the sedimentation bed 600 and is rotated by the force of the refrigerant moving. In the embodiment, the sedimentation device 600 is installed at a position lower than the end of the drainage passage 400 through which the refrigerant is discharged, and the rotary device 500 is installed on the path where the refrigerant is drained from the drainage passage 400 to the sedimentation device 600 Respectively. The rotating device 500 is rotated by the force of the refrigerant falling or the flow rate of the refrigerant.

The rotary device 500 includes a rotary part 510 rotatable by a flow or a flow rate of a refrigerant, a support 520 supporting the rotary part 510, And a rotating body installed to be connected to the rotating body and rotated together with the rotating body.

The rotation unit 510 includes a plurality of rotatable rotation shafts 511 extending in one direction and extending in a direction corresponding to the extending direction of the rotation shafts 511, And includes a blade 512.

The rotary shaft 511 according to the embodiment has a circular cross-sectional shape, for example, and the plurality of blades are plate-shaped and spaced apart at regular intervals. The extension length of the rotation axis 511 is longer than that of the blade 512 so that one end of the rotation axis 511 is positioned at one side of the plurality of blades 512, (Not shown). A rotating body 530, which will be described later, is connected to one end of the protruding rotating shaft 511.

The pair of support rods 520 are spaced apart from each other in the direction of extension of the rotation part 510 and may be installed on the upper part of the settling paper 600. The support unit 520 is installed on the sedimentation unit 600 but the present invention is not limited thereto and the support unit 520 may be installed at various positions so that the rotation unit 510 can be positioned between the drainage passage 400 and the sedimentation unit 600 have. For example, a support base 520 may be provided on the ground, or a support block 520 may be installed on the support block after a separate support block is installed on the ground.

The rotating body 530 is a plate or bar extending in one direction and is fixed to the rotating shaft in a direction intersecting the extending direction of the rotating shaft 511. [ Accordingly, when viewed from the one end of the rotating shaft 511, the rotating body 530 protrudes outward in the direction intersecting the extending direction of the rotating shaft 511. [ The rotation body 530 is rotated together with the rotation of the rotation unit 510 so that the sensor 910 of the injection control module 900 described below can sense the rotation of the rotation unit 510.

In the above description, one end of the rotating shaft 511 is protruded so as to be positioned further outward than the one end of the blade 512, and the rotating body 530 is installed at one end of the rotating shaft 511. However, the present invention is not limited to this, and the extension length of the rotary shaft 511 is the same as that of the blade 512, and another connecting member is further provided at one end of the rotary shaft 511 so that the connecting member protrudes to one side of the blade And a rotating body may be installed on the connecting member.

The injection control module 900 is disposed at one side of the rotating device 500 and includes a sensor 910 for detecting the rotation of the rotating device 500 and a rotation sensor for detecting the rotation signal of the rotating device 500 sensed by the sensor 910, A rotation duration comparator 940 for comparing the rotation duration of the detected rotation device 500 with a predetermined reference rotation time, a rotation speed detector 920 for detecting the rotation speed of the rotation device 500, The control unit 930 controls the injection amount of the refrigerant and the injection amount according to the result of the comparison by the rotation number comparing unit 930, the rotation duration comparing unit 940, and the rotation number comparing unit 930, (950).

The sensor 910 senses the rotation of the rotation part 510 and is installed on one side of the rotation part 510. [ More specifically, it is fixedly installed so as to be located within the turning radius of the rotating body 530. The sensor 910 according to the embodiment includes a light emitting unit that emits light in a direction in which the rotating body 530 is located, and a receiver that receives the irradiated light.

According to the sensor 910 having the light emitting unit and the light receiving unit described above, when the light emitted from the light emitting unit is received by the light receiving unit, the light receiving signal is transmitted to the injection control module 900. At this time, in order for the light irradiated from the light emitting portion to be received back to the light receiving portion, light must be reflected, that is, the reflector must be positioned at a position opposite to the front of the sensor 910, ). That is, when the rotating body 530 in rotation is positioned corresponding to the front position of the sensor 910, the light emitted from the light emitting portion is reflected by the rotating body and is received by the light receiving portion. However, when the rotating rotating body 530 is positioned so as not to correspond to the front of the sensor 910 and to move away from the sensor 910 or to depart from the sensor 910, the light irradiated from the light emitting portion is not reflected, . At this time, since the sensor 910 is fixedly installed at a position within the rotation radius of the rotating body 530 as described above, when the rotating body rotates by 360 degrees on the basis of the position of the sensor 910, Is received.

The detection unit 920 detects or converts the rotation rate and the rotation time value per unit time using the rotation signal of the rotation unit 500 sensed by the sensor 910, that is, the rotation unit 510. That is, the signal received by the light receiving unit of the sensor 910 is transmitted to the detecting unit 920. Whenever the rotating body 530 connected to the rotating rotating unit 510 is positioned to correspond to the sensor 910, Is reflected from the rotating body 530 and is incident on the light receiving section, and this signal is transmitted to the detecting section 920. That is, light is incident on the light receiving unit every time the rotating body 530 rotates by 360 degrees. Thus, light is incident on the light receiving section by the rotating body 530 in rotation for a plurality of times, which is transmitted to the detection section 920. The detection unit 920 analyzes a plurality of signals transmitted from the light receiving unit according to time, and detects the number of incident signals per time and the interval of incident signals. In other words, the number of signals input per time is the number of rotations per hour of the rotation unit 510, and the interval of the incident signals is the time required for the rotation unit 510 or the rotation unit to rotate by one or 360 degrees. Accordingly, in the detection unit 920, the plurality of signals transmitted from the light-receiving unit can be analyzed according to time, thereby detecting the number of revolutions per hour of the rotation unit 510, the time or rotation interval required for 360 ° rotation, .

On the other hand, when the red coke is injected normally in the fire extinguisher 100, the amount of refrigerant discharged from the fire extinguisher 100 to the drainage passage 400 is equal to or greater than a certain amount, and the traveling speed of the refrigerant (flow velocity) At this time, the number of revolutions per hour of the rotating part 510 rotating by the flow of the refrigerant is more than a certain number of times. On the other hand, when the injection quantity of the cold water sprayed by the glowing coke C is insufficient, the amount of refrigerant discharged from the fire extinguisher 100 to the drain is less than a predetermined amount, and the traveling speed (flow velocity) of the refrigerant becomes less than a constant speed. At this time, the number of rotations per hour of the rotation unit 510 is less than a predetermined number.

Accordingly, in the embodiment of the present invention, the number of rotations per hour of the rotation unit 510 is set as the reference rotation number when the coolant is normally injected to determine whether the injection amount of the coolant is normal or abnormal. Here, the reference rotation number may be a range value.

The number-of-rotations comparator 930 compares the number of revolutions per hour of the detected rotation part 510 with the reference number of revolutions to judge whether the current state of the refrigerant is normal or abnormal. That is, when the detected number of revolutions per unit time of the rotation part 510 is included or corresponded to the reference number of revolutions, it is determined that the present state of the refrigerant is normal. Conversely, when the detected number of revolutions per hour of the rotation part 510 is less than the reference number of revolutions, it is judged that the injection of the present coolant is abnormal, more specifically, the injection amount per hour of the coolant is insufficient.

Further, in order to normally extinguish the glow-colored coke (C), the coolant must be injected for a certain period of time. If the injection time is short, the glow coke can not be digested and fire may occur. That is, in order to normally extinguish the glow-plugged coke, the coolant is injected for a predetermined period of time, and the rotation of the rotation unit 510 continues for a predetermined time. If the injection time is insufficient, the rotation duration of the rotation unit 510 becomes less than a predetermined time .

Accordingly, in the embodiment of the present invention, the duration of rotation of the rotating part 510 is detected, and the duration of the refrigerant sprayed by the red hot coke is detected to determine whether the extinguishing time of the red hot coke is normal or abnormal. For this determination, the rotation duration of the rotation unit 510, which normally injects the red coke, is set as the reference rotation duration. The reference rotation duration may be a range value.

The rotation duration time of the rotation unit 510 is determined as the rotation of the rotation unit 510 is stopped because the injection is stopped from the time when the fire extinguishing charge is charged into the fire extinguisher 100 and the injection is started and the rotation unit 510 starts to rotate Time to the point of time. The determination that the rotation of the rotation unit 510 is stopped is performed by the detection unit 920. When the interval between the signals input to the detection unit 920 or the time required for 360 rotation is longer than the preset reference time , It is determined that the rotation of the rotation unit 510 is stopped. Then, the rotation duration of the rotation unit 510 is from the rotation start time to the rotation stop time.

The rotation duration comparator 940 compares the detected rotation duration with the reference rotation duration to determine whether the time of injecting the refrigerant into the red coke is normal or abnormal. That is, when the detected rotation duration of the rotation part 510 is included or corresponded to the reference rotation duration, it is determined that the time when the coolant is injected into the red coke is normal. However, when the detected rotation duration of the rotation part 510 is less than the reference rotation duration, it is determined that the time for injecting the coolant into the red coke is insufficient. When the detected rotation duration of the rotation unit 510 is less than the reference rotation duration, it is determined that the refrigerant in the coolant tank has been exhausted and the supply of the coolant to the coolant supply line has not been completed.

The control unit 950 controls the coolant injection amount and the coolant injection according to the comparison result in the rotation speed comparator 930 and the rotation duration comparison unit 940. That is, if the number of revolutions per hour of the rotation part 510 detected by the revolving number comparing part 930 is included or corresponded to the reference number of revolutions and is determined to be normal, the controller 950 maintains the current amount of the refrigerant. However, if the detected number of revolutions per hour of the rotation part 510 is less than the reference number of revolutions, it is determined that the amount of the refrigerant is insufficient, and the controller 950 increases the amount of refrigerant supplied to the spray tower. This is controllable by adjusting the valve of the refrigerant supply line 200 by the control unit.

When the rotation duration time of the rotation unit 510 detected by the rotation duration comparison unit 940 is included or corresponded to the reference rotation duration time and is determined to be normal, the injection of the coolant is maintained in a stopped state, (10) to be discharged from the digester (100). On the contrary, when the detected rotation duration of the rotation part 510 is less than the reference rotation duration, it is determined that the glowing coke C is not extinguished. This is because the refrigerant in the refrigerant tank 300 is short or exhausted Thus, the control unit 950 supplies the refrigerant to the refrigerant tank 300 to continue the refrigerant injection. This is controllable by the control unit 950 operating the pump 700 installed on the path of the recovery line 800 and adjusting the refrigerant of the sedimentation tank 600 to be supplied to the refrigerant tank 300.

FIG. 5 is a flowchart illustrating an operation of a glow plug coke fire extinguishing system according to an embodiment of the present invention.

Hereinafter, a method of operating and extinguishing a glow-plug coke fire extinguishing system according to an embodiment of the present invention will be described with reference to FIGS. 1 to 5. FIG.

First, the red coke C prepared in the coke oven is charged into the fire extinguisher, and the fire extinguisher 10 is moved into the fire extinguisher 100 (S100).

The valve 210 provided in the refrigerant supply line 200 connecting the refrigerant tank 300 and the digester 100 is opened S200 and the refrigerant is sprayed from a plurality of nozzles provided in the digester 100 , And starts the extinguishing of the glowing coke (C).

When the refrigerant is sprayed toward the red coke from the digester tower 100, the injected refrigerant moves to the sedimentation unit 600 through the drainage path 400 connected to the digestion tower 100. The rotary unit 500 is installed between the drainage passage 400 and the sedimentation station 600 so that the rotary unit 510 of the rotary unit 500 is rotated by the refrigerant moving from the drainage passage 400 to the sedimentation station 600 do. The sensor 910 installed on one side of the rotation part 510 detects the rotation of the rotation part installed on the rotation part 510 (S300).

The detection unit 920 receives the signal from the sensor 910, detects the rotation speed per hour, the rotation duration of the rotation unit 510, and the rotation duration time.

Then, the number-of-revolutions comparator 930 compares the detected number of revolutions per hour with the reference number of revolutions (400). At this time, for example, if the detected number of revolutions per hour is less than the reference number of revolutions, it is determined that the amount of refrigerant is insufficient and the opening rate of the valve 210 is adjusted or increased (S410).

When the detection unit 920 detects the continuation of the rotation of the rotation unit 510 in step S500, the interval between the signals input to the detection unit 920 or the time required for the rotation of the rotation unit exceeds 360 seconds , It is determined that the rotation of the rotation unit 510 is stopped and it is determined that the rotation of the rotation unit 510 is continuing if the rotation is within the preset reference time.

If the detection unit 920 determines that the rotation of the rotation unit 510 is stopped, the rotation duration comparing unit 940 compares the detected rotation duration with the reference rotation time (S600). At this time, if the detected rotation duration is less than the reference rotation duration, the controller 950 operates the pump 700 installed in the recovery line 800 to supply the refrigerant of the sedimentation tank 600 to the refrigerant tank 300 Supplement. As another example, if the detected rotation duration corresponds to or exceeds the reference rotation duration, the valve 210 is closed (S700) and the fire extinguisher 10 is taken out of the fire extinguisher 100 (S800).

As described above, according to the embodiment of the present invention, while rotating the rotary device in accordance with the drainage of the refrigerant, the rotation of the rotary device 500 is sensed while the hot coke is being extinguished by spraying the refrigerant in the fire extinguisher 100 , It is determined whether the injection amount of the refrigerant is normal or the time when the injection of the refrigerant is continued is normal. The heat release coke can be completely extinguished by adjusting the opening ratio of the valve 210 or supplementing the refrigerant to the refrigerant tank 300 according to the determination result so that the gypsum coke C can be sufficiently extinguished , It is possible to prevent a fire from occurring due to insufficient digestion.
