Description
technical field:
The utility model relates to a kind of coke oven emission pipe and diffuses safely igniter, belongs to automation field.
background technology:
The exhaust stack in coke oven region is that fluctuation appears in coke oven pressure, when system breaks down, light by exhaust stack, thereby realize a kind of device coal gas of pressures inside fully being burnt and design, break down once coke oven, must light in time the raw coke oven gas of discharging in exhaust stack, otherwise, environmental pollution meeting is very serious, at present in routine techniques, the firing technique of exhaust stack is adopted to PLC centralized Control substantially, send a signal by artificial scene, control PLC output firing command, its instruction general control contactor action, after contactor adhesive, controlling on-the-spot pulse transformer obtains electric, pulse transformer carries out high-frequency impulse igniting to ignition mechanism, this mode is from controlling, substantially no problem, but in actual use, problem is very many, first oven top of coke oven temperature is very high, hyperthermia radiation is serious, also be a kind of badly damaged to cable, the phenomenon of naked light scaling loss cable is also very many, once certain some cable short circuit, to directly have influence on PLC output and control effect, centralized Control is become can not be controlled.
utility model content:
The purpose of this utility model is to provide a kind of coke oven emission pipe to diffuse safely igniter for the problem of above-mentioned existence, by the reception of an output order, realizes the independent of coke oven emission igniting and controls, and guarantee firing command, carries out the prompting of audible alarm.
Above-mentioned object realizes by following technical scheme:
Coke oven emission pipe diffuses safely igniter, comprise the button ignition switch SB1 and the igniting contactor KM that are connected with electric control loop, described button ignition switch SB1 and igniting contactor KM one group of auxiliary contact drive ignition device J in parallel, each described auxiliary contact drive ignition device comprises power supply GB, described power supply is by linked switch K tie point ignition circuit, and described linked switch connects independent manual ignition button SB3.
Described coke oven emission pipe diffuses safely igniter, described firing circuit comprises the infrared photocell VD1 and the triode VT1 that are connected with linked switch K by resistance R 1, described triode VT1 connects oscillation transformer TI and triode VT2, and described oscillation transformer T1 connects igniting contact A by capacitor C 2, diode VD3, unidirectional thyristor VS and high-tension transformer T2.
Described coke oven emission pipe diffuses safely igniter, and described oscillation transformer TI comprises primary coil L1, L2 and secondary coil L3, and described primary coil L1 is parallel with piezoelectric ceramic piece BC.
Beneficial effect:
1. the utility model is considered by on-the-spot environmental factor, concentrate and send firing command by a device SB1, by its auxiliary contact drive unit J (J1-J10 in Fig. 1), each igniter is arranged on the side of exhaust stack, by storage battery power supply independently, when system is received after firing command, system assignment is to J1-J10 in figure, each controller obtains after firing command, carry out pulse firing, and consider igniting after failure, remind, and automatically realize regnition, be provided with independently manual ignition button SB3, in the time concentrating igniting to break down, only need to touch its button ignition switch SB3 just can realize independent igniting.
2. once the utility model is because unexpected steam stove extinguishes, infrared ray is die-offed and is even disappeared, and the piezoelectric ceramic piece BC that is connected in parallel on elementary L1 two ends sends loud buzzing chimes of doom owing to obtaining induced voltage.If steam stove can not be lighted all the time, chimes of doom yowls constantly, to attract much attention, is processed accordingly, plays double protection.
brief description of the drawings:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the circuit diagram of firing circuit of the present utility model.
detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Embodiment 1:
As shown in Figure 1: the coke oven emission pipe of the present embodiment diffuses safely igniter, comprise the button ignition switch SB1 and the igniting contactor KM that are connected with electric control loop, described button ignition switch SB1 and igniting contactor KM one group of auxiliary contact drive ignition device J in parallel, each described auxiliary contact drive ignition device comprises power supply GB, described power supply is by linked switch K tie point ignition circuit, and described linked switch connects independent manual ignition button SB3.
Embodiment 2:
As shown in Figure 2, firing circuit described in the present embodiment comprises the infrared photocell VD1 and the triode VT1 that are connected with linked switch K by resistance R 1, described triode VT1 connects oscillation transformer TI and triode VT2, and described oscillation transformer T1 connects igniting contact A by capacitor C 2, diode VD3, unidirectional thyristor VS and high-tension transformer T2.
Embodiment 3:
The difference of the present embodiment and embodiment 1 or embodiment 2 is, described oscillation transformer TI comprises primary coil L1, L2 and secondary coil L3, and described primary coil L1 is parallel with piezoelectric ceramic piece BC.
The course of work:
While firing the igniter of exhaust stack as main points, first press button ignition switch (SB1 in Fig. 1), igniting contactor KM adhesive, then by auxiliary contact drive ignition device (J1-J10 in Fig. 1), can find out in device, there is a secondary contactless ignition K adhesive (in Fig. 2) by the schematic diagram of device, the closing of contact is sent into each ignition signal to be positioned at the other driver module of exhaust stack, by principle analysis, in the time of enabling signal adhesive, linked switch K connects simultaneously.Now because steam stove is not yet lighted, infrared photocell VD1 internal resistance is very high, triode VT1 conducting, the oscillation circuit of forming to L1, L2 in triode VT2, oscillation transformer T1 provides bias current to make it starting of oscillation, thereby the secondary L3 two ends at T1 induce over one hundred volt voltage, after diode VD2 rectification, give capacitor C 2, C3, diode VD3, unidirectional thyristor VS and T2 level L2 two ends of high-tension transformer, be the high-voltage pulse that igniter discharge end induces volts up to ten thousand, ionized air produces continuous high-temperature electric spark to light gas.
After steam stove is lighted, high-temperature combustion gas will give off strong infrared ray, is converted into low spot position and adds to the base stage of triode VT1 in Fig. 2, thereby impel VT1 cut-off in Fig. 2 by VD1 reception in detector Fig. 2, in late-class circuit Fig. 2, VT2 loses bias current and failure of oscillation, and igniter quits work automatically.Once because unexpected steam stove extinguishes, infrared ray is die-offed even and to be disappeared, in Fig. 2, VD1 gets back to former high-impedance state, VT1 conducting in Fig. 2, the rear polar circuit work output continuously sparking gas that again ignites.Meanwhile, the piezoelectric ceramic piece BC that is connected in parallel on elementary L1 two ends sends loud buzzing chimes of doom owing to obtaining induced voltage.If steam stove can not be lighted all the time, chimes of doom yowls constantly, to attract much attention, is processed accordingly, plays double protection.
