Detailed description of the invention
[embodiment 1]
This patent adopts the principle of flame ion detection technique to be when fuel gas burns on altar lamp, and the base portion in combustion zone can produce ionized gas, and ionized gas has electric conductivity, and small area analysis can be allowed to pass through.Utilize this character of ionized gas, a flame ion probe is placed in flame region, when flame combustion, electric current is passed to altar lamp by ionized gas from probe, thus produces little electric current, when flame does not burn, electric current cannot be passed to altar lamp from probe, also just cannot generation current.By monitoring conducting end current signal, just can judge whether altar lamp has flame combustion fast.
This patent Structure Figure as shown in Figure 1, comprise ground flare burner 1, flame ion detection system 2, connect floor 3, ignition system 4, altar lamp 5, flame ion detection system 2 mainly contains flame ion probe 7, circuit board 6 and shielded cable 9 and forms, and detects response time < 1s.Flame ion probe 7 is arranged on torch altar lamp which burns day and night 5 top, and circuit board 6 is located at Central Control Room, and probe 7 is connected by shielded cable 9 with circuit board 6.Circuit board 6 by flame ion probe 7 detect ionization gas cloud cluster near altar lamp nozzle in flame with or without, thus judge the flame combustion state of altar lamp.The detection pole of flame ion probe front is arranged in the hurricane globe 11 of altar lamp, can effectively avoid strong wind weather to cause altar lamp flame lifting on the impact of testing result.Circuit board 6 is designed with Short Circuit withstand interference sections, effectively can resist rainwater and cause flame ion probe short circuit to the interference of fire defector result.Circuit board 6 is provided with 4-20mA current signal and exports, and is convenient to the signal is far passed and control.When flame ion circuit board 6 outputs signal as 20mA, show that altar lamp 5 is in fired state.When flame ion circuit board 6 outputs signal as 4mA, show that altar lamp 5 is in OFF state.Now, automatic control system 13 is interlocked and is driven high pressure generator 10 to light a fire, and ignite altar lamp 5 again.
After fuel gas and air pre-mixing are closed, after high pressure generator 10 is lighted a fire, fuel gas is lighted, by ignition tube 9, flame causes that altar lamp is lighted at altar lamp top.
Altar lamp 5 bottom is provided with adjustable air ejector 12, utilizes venturi principle, is sucked in fuelgas pipeline, is mixed to altar lamp 5 top combustion with fuel gas with the fuel gas of band certain pressure and flow velocity by injector ambient air.Altar lamp 5 is provided with hurricane globe 11 topmost, prevents de-fiery phenomenon.Altar lamp 5 welds floor 3, so that fixing flame ion probe 7 and ignition system 4.
The life-span of flame ion probe is 3 years.
[comparative example]
Adopt thermocouple to detect ground flare altar lamp temperature and judge altar lamp fired state, the response time is 135s, the life-span is 1-2.
Test by experiment, thermocouple monitoring SRT is longer, is about 135s.And after the extinguishing of ground flare altar lamp, because altar lamp temperature declines slowly within long period of time, cause the thermocouple response time long.
In this patent, flame ionisation detection system response time is about 1s, and it can judge the fired state of altar lamp accurately, and output signal easily realizes the judgement of altar lamp fired state and signal is more stable.Once ground flare altar lamp lost efficacy, flammable vapor cloud can not be lighted in time.In 10s, fuel gas is full of torch cylinder space, whole ground, runs into incendiary source and can blast and cause serious consequence.The ground flare altar lamp device that this patent is mentioned to can detect altar lamp fray-out of flame signal in 1s, and can light altar lamp in time, and avoid a nasty accident generation.
