Abstract
The invention belongs to the gasifying device especially relates a kind of safe expansion and preventing fluid gas generator with making the liquid state and liquation oil-gas or propane through the heat exchange sufficiency and forcing the liquid state and liquation oil-gas be vaporized. There is setting up a free style high-voltage non-corrosive steel floating ball in the gasify house and in the gas outlet of gasify house sets up a preventing leakage lock ring and the safe expansion valve is installed on the top of gasify house directly. The invention's benefit effectiveness is that: the floating ball preventing fluid measurement can prevent the liquid gas liquid into the gas conduit effectively and avoid the liquid gas knocking or explosion phenomenon happening at the time of lighting-up the liquid gas; the measurement of safe expansion make the pressure in the house expanded quickly when the pressure in the gasify house increasing fast accordingly assurance the gasify device running normally and safely.
Description
Technical field
The invention belongs to gasification installation, particularly a kind of a kind of safety that makes liquid liquefied petroleum gas be forced to vaporize by sufficient heat exchange in liquid liquefied petroleum gas or propane is diffused and the vaporizer of preventing liquid.
Background technique
Gasification installation is a kind of a kind of gasification installation that makes liquid liquefied petroleum gas be forced to vaporize by sufficient heat exchange in liquid liquefied petroleum gas or propane, and liquefied petroleum gas (LPG) or propane are a kind of inflammable, explosive hazardous chemical fuel.It one of the most obvious characteristic be liquid liquefied petroleum gas or propane be transformed into by liquid state in the process of gaseous state its volume can rapid expansion 250-300 doubly.As a kind of forced gasification device, design is unreasonable if in case the safety of equipment itself is diffused measure, the gas that is inflated can not be diffused outside the device body rapidly, cause the rapid rising of apparatus body internal pressure, during the limit that the equipment of reaching bears pressure equipment explosion can take place and cause the in use very large potential safety hazard of equipment.In addition, as a kind of forced gasification device, if can not prevent that not vaporized liquid from entering the liquid device of preventing of gas transmission pipeline by the good equipment for gasification of good treatment itself, will cause gas equipment that detonation, explosive incident generation in use take place, even injure producers' life.
Though at present domestic a lot of manufacturers diffuse and prevented having taked some measures aspect the liquid in gasification installation safety, its effect is also not obvious.Wherein a kind ofly prevented that the liquid measure was: adopt long enclosed explosion-proof solenoid valve (seeing structural drawing 2), though this mode seems comparison safety when the equipment initial launch, but because solenoid valve itself has the tired time limit and seal erosion wear phenomenon, in case solenoid valve reaches fatigue strength and lifetime limitation or because the corrosion of liquid gas damages sealing gasket, will lose anti-liquid effect, in case the equipment liquid lng that breaks down enters gas equipment inside like this, when lighting liquid gas liquid gas detonation or explosion phenomenon will certainly appear, the threat to life property safety.Another kind prevented that the liquid measure was: adopt the guiding rod-type to prevent that the liquid float (saw structural drawing 3-Fig. 4), there is very big drawback in this mode when equipment operation, the one, the gap between guide rod and the directed cavity is unsuitable excessive or too small, pilot hole is excessive, the float dish is just to equally upwards operation of tumbler, finally can not be fully with the gas outlet sealing, cause liquid to enter gas pipeline and detonation or explosion phenomenon occur.The 2nd, liquid gas itself has a lot of impurity, the liquid liquid gas can produce coking phenomenon in gasification, along with the equipment growth of service time, thereby the coking material of these thickness can stop up pilot hole with attaching on guide rod, die float to be in promptly to go up and do not come again the following state that does not go, lose and prevent that liquid from flowing into the effect of gas pipeline, be easy to make liquid lng to enter gas equipment inside like this, when lighting liquid gas, be certain to occur liquid gas detonation or explosion phenomenon, the threat to life property safety.
Equipment for gasification is again a kind of pressure resistant vessel, its pressure-bearing part is fully in gasification room, two kinds of above-mentioned equipment (are seen that structural drawing 2-Fig. 4) all is arranged on Safety relief valve on the pipeline of gas outlet, can not be played when the gasification room internal pressure raises rapidly from the equipment work principle at all and reach the purpose that safety is diffused.
Summary of the invention
Main purpose of the present invention is to overcome gasification installation and diffuses and the deficiency of preventing liquid measure design aspect in safety, provide a kind of effective reaching to prevent that liquid gas liquid from entering in the gas pipeline, other makes when the gasification room internal pressure raises rapidly the gasification room internal pressure be diffused rapidly, thereby guarantee the operation of the normal safety of equipment for gasification, effectively avoid the safety that when lighting liquid gas liquid gas detonation or explosion phenomenon take place to diffuse and the vaporizer of preventing liquid.
For realizing purpose of the present invention, the technological scheme that adopts is, a kind of safety is diffused and the vaporizer of preventing liquid, mainly comprise gasification room, liquid-inlet, gas outlet and Safety relief valve, it is characterized in that: in gasification room, be provided with the high pressure resistant stainless steel floating ball of free style, be provided with the leak-tight seal circle at the gasification room gas outlet, its Safety relief valve is directly installed on the top of gasification room.
Ball float in the above-mentioned gasification room is provided with 1～3, can do 360 ° of rotations in gasification room.
Above-mentioned seal ring adopts the nitrile rubber seal ring.
The invention has the beneficial effects as follows: floating ball preventing of the present invention is crossed the liquid measure, and effective reaching prevents that liquid gas liquid from entering in the gas pipeline, effectively avoids liquid gas detonation or explosion phenomenon generation when lighting liquid gas; The safety measure of diffusing makes that the gasification room internal pressure is diffused rapidly when the gasification room internal pressure raises rapidly, thereby guarantees the operation of the normal safety of equipment for gasification.

Fig. 2 is the existing equipment for gasification structural representation that adopts long enclosed explosion-proof solenoid valve;
Fig. 3 is the existing equipment for gasification structural representation that adopts the guiding rod-type to prevent the liquid float; .
Fig. 4 is that Fig. 3 rod-type that leads was prevented the enlarged view of liquid float.
Embodiment
Please refer to accompanying drawing 1, a kind of safety is diffused and the vaporizer of preventing liquid, mainly by gasification room 1, liquid-inlet 2, gas outlet 4 and Safety relief valve 3, in gasification room 1, be provided with 3 high pressure resistant stainless steel floating balls 6 of free style, ball float can be done 360 ° of rotations in gasification room, do not have any guiding, relies on the buoyancy of liquid gas itself to move up and down fully, effective reaching prevents that liquid gas liquid from entering in the gas pipeline, effectively avoids liquid gas detonation or explosion phenomenon generation when lighting liquid gas.Be provided with anti-leak nitrile rubber seal ring 5 at gasification room 1 gas outlet, when ball float 6 rises, the tighter gas outlet of blocking.Its Safety relief valve is directly installed on the top of gasification room, makes that the gasification room internal pressure is diffused rapidly when the gasification room internal pressure raises rapidly, thereby guarantees the operation of the normal safety of equipment for gasification.
Project organization of the present invention is through repetition test, the safety of gasification installation is diffused and prevented that the liquid measure had obtained effective improvement.
