Abstract
The utility model relates to a safety protection system for a gas generator set, which is an improvement on a present gas generator set. The safety protection system adopts the technical scheme that a fire arrestor and an anti-explosion electromagnetic valve are sequentially arranged on a gas inlet pipeline in the gas flow direction and positioned before a mixer, and an anti-explosion pressure-relief device is arranged on an exhaust pipe. The safety protection system for the gas generator set effectively solves the problems of gas leakage, explosion prevention, pressure relief, fire flashback and the like, and improves the safety protection function for the gas generator set.
Description
Technical field
The utility model relates to a kind of safety system of fuel gas generation unit.
Background technique
The fuel gas generation unit is to adapt to world's environmental requirement and the new environment in market and the new-generation unit developed, is the only way of realizing energy-saving and emission-reduction and energy supply sustainable development.It takes full advantage of various rock gases or harmful gas acts as a fuel, and turns waste into wealth, safe and convenient operation, and cost benefit is high, exhaust emission is low, and the advantages such as heat, Electricity Federation product that suit, market prospects are very wide, are the irreversible trends of modern energy field development.
Yet; existing fuel gas generation unit exists the problem that some demand urgently improving aspect safety and reliability; adopt the protection diaphragm to process such as fuel gas generation unit burning and gas-exhausting pressure protect; this protection diaphragm can only disposablely use; can break through diaphragm when burning and gas-exhausting pressure is excessive; need to again change diaphragm, the inadequate science of this design.Moreover existing fuel gas generation unit does not have air inlet anti-leak protection device, can't guarantee air inlet safety; Do not have fuel gas fire arrestor, in case the combustion gas tempering occurs, can't effectively stop fire spreading to generator set, can't guarantee the safety of generator set and source of the gas.
The model utility content
In order to solve above technical problem; the utility model improves existing fuel gas generation unit; air inlet anti-leak protection device, burning and gas-exhausting pressure explosion-proof protective gear and back fire protection device have been set up; efficiently solve gas leakage, explosion-proof relief, the intensity of a fire problem such as strile-back, improved the safety protection function of fuel gas generation unit.
To achieve these goals; the utility model provides following technological scheme; fuel gas generation unit safety system; comprise fuel gas generation unit, air inlet pipeline, gas exhaust piping; before mixer on the gas inlet pipeline, set gradually flame trap and explosion-proof solenoid valve according to the gas trend, at outlet pipe explosion-proof decompression device is set.
Further, described flame trap is arranged on the air inlet pipeline, and when unit generation tempering, fuel gas fire arrestor can be eliminated naked light, prevents that fire spreading is to caisson.
Further, described explosion-proof solenoid valve is arranged on the air inlet pipeline, is positioned at the rear of flame trap, and when unit was in outage state, explosion-proof solenoid valve was closed, and cuts off the gas supply pipeline; When unit start operation, the explosion-proof solenoid valve energising is opened to the unit air feed.Explosion-proof solenoid valve can guarantee that unit stops the leakage of combustion gas when shutting down.
Further, described explosion-proof decompression device comprises the pressure transducer that is arranged on fuel gas generation unit gas exhaust piping.Enter outlet pipe behind the fuel gas buring, when pressure transducer detected high-temperature gas pressure and is higher than the force value of setting, explosion-proof decompression device was opened, and carries out pressure release; After the pressure release, when outlet pipe pressure was lower than setting value, explosion-proof decompression device was closed.Explosion-proof decompression device can prevent effectively that the air pressure of gas exhaust piping is too high, and the protection unit normally moves, and prevents explosive accident.
The fuel gas generation unit safety system that adopts the utility model to provide efficiently solves the problems such as gas leakage, explosion-proof relief, the intensity of a fire strile-back, and has improved the safety protection function of fuel gas generation unit.

Embodiment
Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is done further detailed, clear, complete explanation, meet novelty, creativeness and the practicability that Patent Law requires fully with explanation the utility model.What should be noted that embodiment describes is a part of mode of execution of the present utility model, can not be used for limiting protection domain of the present utility model.
As shown in Figure 1; fuel gas generation unit safety system; comprise fuel gas generation unit 1, air inlet pipeline 2, gas exhaust piping 3, before mixer 4 on the gas inlet pipeline 2, set gradually flame trap 5 and explosion-proof solenoid valve 6 according to the gas trend, at gas exhaust piping 3 explosion-proof decompression device 7 is set.
Further, described flame trap 5 is arranged on the air inlet pipeline 2, and when unit generation tempering, fuel gas fire arrestor can be eliminated naked light, prevents that fire spreading is to caisson.
Further, described explosion-proof solenoid valve 6 is arranged on the air inlet pipeline 2, is positioned at after the flame trap 5, and when unit 1 was in outage state, explosion-proof solenoid valve 6 was closed, and cuts off the gas supply pipeline; When unit 1 start operation, explosion-proof solenoid valve 6 energisings are opened to the unit air feed.Explosion-proof solenoid valve can guarantee that unit stops the leakage of combustion gas when shutting down.
Further, described explosion-proof decompression device 7 comprises the pressure transducer 8 that is arranged on fuel gas generation unit gas exhaust piping 3.Enter outlet pipe 3 behind the fuel gas buring, when pressure transducer 8 detected high-temperature gas pressure and is higher than the force value of setting, explosion-proof decompression device 7 was opened, and carries out pressure release; After the pressure release, when outlet pipe pressure was lower than setting value, explosion-proof decompression device 7 was closed.Explosion-proof decompression device can prevent effectively that the air pressure of gas exhaust piping is too high, and the protection unit normally moves, and prevents explosive accident.
