Description
Technical field
The utility model relates to a kind of igniter, and particularly a kind of high energy ignition unit that is applied in the ignition control system of tube furnace also is applicable in the body of heater ignition system of other type.
Background technology
Tubular heater is a kind of firepower firing equipment, it utilizes thermal-flame that fuel produces when the burner hearth internal combustion and flue gas as thermal source, the medium that heating is flowed in the boiler tube high speed, make it reach the temperature of process stipulation, to supply with medium needed heat in carrying out process such as fractionation, cracking or reaction, guarantee to produce and normally carry out.Compare with other mode of heating, the major advantage of tubular heater is heating-up temperature height (can reach 1273K), and heat-transfer capability is big and be convenient to operational administrative.
In tube furnace, heated material flows in pipe, so only limit to heated air and liquid.And these gases or liquid all are inflammable and explosive hydrocarbons usually, add hot water and vapor phase ratio with boiler, and is dangerous big, and it is much harsh that operating condition is wanted.In addition, tube furnace only burns gas or liquid fuel, and gas and liquid fuel be easy detonation when improper use, domestic a lot of industrial furnace deflagration accident havings takes place once.All the time, igniting is not used widely in tube furnace automatically, the artificial torch igniting of many both at home and abroad employings.Particularly at home, because tube furnace is used widely in recent years, a lot of tube furnaces do not have supporting Iganition control system and combustion control system.This makes the startup of tube furnace and operation have serious potential safety hazard, and benefit is low, causes energy waste and environmental pollution.The first step that burner puts into operation is lighted flammable mixture formation flame exactly, enters normal combustion then.Igniting is exactly the thermal source that imports the temperature height and have certain energy in fuel-air mixture, earlier local mixture is lighted, and then is propagated diffusion and sustained combustion, and this high temperature heat source is exactly an incendiary source.
At present, nearly all adopt spark ignition on the oil gas burner, even, also light by electric spark with the flammule igniting, and then the main fire that ignites.Electric spark is to puncture the spark that gas gap forms because of high-tension electricity between two electrodes.The normal method that adopts is with step-up transformer voltage to be raise on the industrial burner, and the discharge generation spark is lighted a fire between two electrodes.Adopt this electric sparking mode exist simple in structure, service life is short and spark energy is little, insecure shortcoming of lighting a fire.
Summary of the invention
The purpose of this utility model provides a kind of pilot spark energy height, and is safe and reliable, the explosive-proof grade height, can realize the automatically high energy ignition unit of igniting.
The utility model is achieved through the following technical solutions:
High energy ignition unit, connect to form successively by igniter, high-tension shielding cable, burning torch, igniter is made up of step-up transformer L, rectifier D, capacitor C1, discharge tube C2, choke coil L1, resistance R 1, resistance R 2, resistance R 3, step-up transformer L output connects rectifier D, rectifier D output connects resistance R 1, resistance R 1 output connects capacitor C1 and discharge tube C2, capacitor C1 and resistance R 2 parallel connections, discharge tube C2 output connects resistance R 3 and choke coil L1.
Compared with prior art, the beneficial effects of the utility model are: guaranteed safety of ignition and reliability, and pilot spark energy height, safe and reliable, the explosive-proof grade height can be realized automatic igniting, for the automatic control system of tube furnace provides the foundation.
Description of drawings
Fig. 1 is the structure chart of high energy ignition unit;
Fig. 2 is the circuit structure diagram of igniter.
The specific embodiment
Be described in detail the technical solution of the utility model below in conjunction with accompanying drawing:
See Fig. 1, high energy ignition unit is by igniter 2, high-tension shielding cable 3, burning torch 1 connects to form successively, see Fig. 2, igniter is by step-up transformer L, rectifier D, capacitor C1, discharge tube C2, choke coil L1, resistance R 1, resistance R 2, resistance R 3 is formed, step-up transformer L output connects rectifier D, rectifier D output connects resistance R 1, resistance R 1 output connects capacitor C1 and discharge tube C2, capacitor C1 and resistance R 2 parallel connections, discharge tube C2 output connects resistance R 3 and choke coil L1, igniter 11 becomes the dc pulse electric current with the voltage of AC power frequency 220V or 110V through the rectifying conversion that boosts, energy-storage capacitor is charged, when energy-storage capacitor is full of, discharge current is through discharge tube C2, choke coil L1, high-tension shielding cable 11 transfers to burning torch 9, forms the high energy arc spark.When igniter quit work, the residual charge on the capacitor was released by bleeder resistance.The pilot spark energy height of high energy ignition unit, safe and reliable, the explosive-proof grade height.
Capacity Discharge Type Ignitor and electronic striking mode are lighted a fire is compared as follows table:
| Item compared | Ignition transformer+ignitor | Capacity Discharge Type Ignitor+burning torch |
| Ignition voltage | Minimum is 5000V | Be up to 2500V |
| Spark energy | Tens milli J | Be generally 20J |
| Install and use | The ignitor fixed installation, | Burning torch can add propulsion plant, and hand-held is also arranged |
