Detailed description of the invention
[embodiment 1]
A kind of ignition controlling system as shown in Figure 1, comprise ignition signal sensor (1), ignition system logical gate (2), high pressure or high-energy igniter (3), igniter fuel air valve (4), altar lamp fuel air valve (5), ignition signal sensor (1) receives pipe network temperature of releasing, pressure, key safety valve take-off signal, and be connected with ignition system logical gate (2) by holding wire, ignition system logical gate (2) by cable respectively with high pressure or high-energy igniter (3), igniter fuel air valve (4), altar lamp fuel air valve (5) is connected, control high pressure or high-energy igniter (3) are lighted a fire and igniter fuel air valve (4), the switch of altar lamp fuel air valve (5), described ignition system logical gate (2) is PLC control system, have fault-tolerant, self-checking function, whole Iganition control system is arranged by certain logical construction.Described igniter fuel air valve (4) outlet is connected with high pressure or high-energy igniter (3) by pipeline, and altar lamp fuel air valve (5) outlet is connected with altar lamp (6) by pipeline.Described logical construction is: ignition signal gets pipe network temperature of releasing, pressure, these three signals of key safety valve take-off, and logical relation is 2oo3; Ignition system logical gate (2) is 1oo2; Redundancy established by high pressure or high-energy igniter (3); Igniter fuel air valve (4), altar lamp fuel air valve (5) all establish bypass in parallel.
When device is released, safety valve jumping up, gas of releasing enters torch (12) after a point flow container (7), water sealed tank (8).When releasing, bleeder pipe linear pressure and temperature are rising, and ignition signal sensor (1) adopts 2oo3 mode, provide the signal that discharge occurs device, and pass to ignition system logical gate (2).
Ignition system logical gate (2) adopts the technical grade PLC with redundancy, self-diagnostic function, guarantees the accuracy of signal transacting.
The igniting model that ignition system logical gate (2) provides passes to high pressure or high-energy igniter (3), igniter fuel air valve (4) and altar lamp fuel air valve (5), start high-energy ignition, altar lamp (6) lighted by high pressure or high-energy igniter (3) afterwards, completes whole firing action.
[comparative example 1]
According to the condition described in embodiment 1, ignition signal only has a kind of mode of pressure sensor.Torch gas contains a large amount of graininess component as carbon granules or crystallization, the impulse mouth of easy retaining pressure sensor.When device is released, because pressure sensor impulse mouth is blocked, pressure relief system change cannot be monitored in time, also just cannot respond in time the process of releasing, finally cause in time starting ignition system to light altar lamp and torch.
[comparative example 2]
According to the condition described in embodiment 1, logical gate adopts general PLC, does not have redundancy and self-diagnostic function.When transducing part detect the process of releasing and output alarm signal to logical gate time, logical gate should make firing command according to the alarm signal of transducing part, but due to logical gate itself fail, logical calculated part for subsequent use is not had again to process sensor alarming signal, cause firing command to provide in time, affect firing action.
[comparative example 3]
According to the condition described in embodiment 1, redundancy do not established by high pressure or high-energy igniter, or igniter fuel air valve, altar lamp fuel air valve do not establish bypass.When logical gate provides firing command, because high pressure or high-energy igniter break down, high-tension electricity cannot be produced or high energy electricity is lighted a fire, cause loss of ignition; Or due to igniter or altar lamp fuel valve fault, cause gas circuit not open in time, also can cause loss of ignition.
