Abstract

The utility model relates to a liquid gas generator. A check safety valve is arranged on a closed container. An air inlet pipe, a vaporizing gas pipe, and a combustible gas output pipe are arranged on the check safety valve, and are communicated with the inner cavity of the check safety valve. A hollow tip is arranged in the inner cavity of the check safety valve. When the utility model is used, the utility model is connected with an air source, and liquid fuel can be vaporized under room temperature. The utility model has the advantages of convenient operation, safe use, simple appliance, long service life, and good vaporizing effect. The utility model can be widely used for heating appliances in the industrial field and the living field, and can be used as a vaporizing appliance of the liquid fuel.

Description

The liquid gas generator

The utility model relates to a kind of liquid gas generator.Particularly a kind of liquid gas generator that liquid fuel is converted into gaseous fuel.

A kind of liquid gas generating means that utilizes heating to make liquid fuel evaporation gasification is arranged in the market, but they have deficiency, at first the heating and gasifying pipe stops up easily or burns out, working life is not long, secondly liquid is carried out the equipment of heating evaporation gasification, the technical requirements height, complex structure, exist the danger that sets off an explosion with fire, in addition, also exist and use inconvenience, dangerous.

The purpose of this utility model provides the liquid gas generator under a kind of normal temperature.

Task of the present utility model realizes with following mode: the non-return safety valve is equipped with on container top, incoming air conduit and hollow combustion gas output tube, the vaporization tracheae of being equipped with below top are housed on the non-return safety valve, have the interior hollow cavity of air outlet hole and top lower part wall to communicate on the hollow top lower part wall.Vaporization tracheae upper end-hole is communicated with the cavity in the non-return safety valve, and lower end mouth is positioned at the bottom of container intracavity.

The utility model makes liquid fuel gasification at normal temperatures, and is easy and simple to handle, safe in utilization, and equipment is simple, long service life, and vaporization effect is good.Can extensively be used on the heating plant in industry and life neck city and use as liquid fuel gasification equipment.

Below in conjunction with accompanying drawing this liquid gas generator is described in further detail: the device of calming the anger is in use selected air pump 8 for use, and air pump 8 is connected incoming air conduit 9.There is cavity non-return safety valve 2 inside, and have incoming air conduit 9, combustion gas output tube 5 and vaporization tracheae 3 to be communicated with it.Be equipped with hollow toply 6 at the inner chamber place of valve, toply can seal incoming air conduit up, a top following perisporium has the hollow cavity in the inner chamber and hollow top 6 of four air outlet hole 7 connecting valves and is communicated with the tracheae 3 of vaporizing.Combustion gas output tube 5 is contained on the valve body of hollow top 6 downsides, and communicates with the inner chamber of valve.Vaporization tracheae 3 is inserted into container 1 inner chamber, and its lower end mouth is near container 1 lower bottom part.Non-return safety valve 2 is contained in position, container 1 upper-end surface.The lid 4 of charging hole sealing usefulness also is housed on container 1.Container 1 is a seal container.The suction port of non-return safety valve 2 links to each other with the air outlet of air pump 8 by incoming air conduit 9, the centre have one hollow top 6, air outlet hole 7 is arranged on it, form an air and enter into passage bottom the fuel; Form again simultaneously one stop withdrawing fluid fuel safety installations.

After reinforced flap 4 was tightened, the liquid fuel of can in container 1 was sealing state, separates fully with air, can only form static evaporation, and gasification rate is very slow, can not form to be transported to the gas flow that burns on the burner.After air pump 8 starts air is pressed in the air flue of non-return safety valve 2, air outwards makes to spray diffusion motion through hollow top 6 air outlet hole 7 through the bottom that vaporization tracheae 3 enters into liquid fuel, makes liquid fuel form the physical phenomenon of a boiling.At this moment, air carries out multidirectional evaporation gasification to fuel inside and surface simultaneously, has accelerated the formation speed of the evaporation and the combination gas of fuel.At this moment, because the kinetic energy of the vapour molecule that produced is greater than the kinetic energy of unevaporated fluid molecule, vapour molecule surpasses the gravitation between fluid molecule and breaks away from liquid level, escapes into the space of liquid level, forms the fuel gas layer that a kind of fuel and air mix mutually.Along with resolving of combustion gas produces and increase, produce a kind of vapour tension, after gas valve was unlocked, the combination gas that has certain vapour tension was just exported for burner combustion continuously.When fuel gas buring, the pressure in the vaporizer is normal, can not cause liquid return.But for avoiding operational mistake, cause producing liquid in the vaporizer along vaporization tracheae 3 to 1 exteenal reflux of vaporizer container, at this moment, hollow top 6 of non-return safety valve can cut out automatically, stop withdrawing fluid, simultaneously, stoped entering of air that fuel is continued the evaporation gasification again, increase the pressure in the vaporizer, thereby guarantee the normal state of vaporizer internal pressure.

Liquid fuel is that C5, C6 or pentane are basic material, adds a spot of oxygenant, volatilizer and synthetics, synthesizes a kind of fuel that has good vapo(u)rability (volatility), easily gasifies, is easy to air formation combination gas through simple the mixing.
