Abstract

The utility model relates to a device for automatically proportioning and transforming liquid and gas for a vaporizing burner, which improves a liquid feeding device of the existing vaporizing burner. An inner transfusion tube which accesses to the inside of a sealing cylinder is sheathed with a sleeve tube of which both of the two ends are sealed; the sleeve tube has a definite gap between an inner wall and the transfusion tube. Both of the two ends of the sleeve tube are respectively provided with small holes; the diameter of an upper air inlet hole is from 1.0 to 1.5 mm, and the diameter of a lower liquid inlet hole is from 0.4 to 0.6 mm. The lower end of the transfusion tube is provided with an opening by the inclined cutting. At the time of ignition, an angle valve is opened, and the liquid inside the sleeve tube is quickly evacuated. The liquid in the cylinder and the air in the cylinder enter the sleeve tube for supplying combustion from the liquid inlet hole and the air inlet hole. After the normal combustion, the opposite pressure formed by the vaporizing inflation of a vaporizing tube causes air intake to automatically stop.

Description

Device for automatically proportioning and transforming of liquid and gas of evaporator

The utility model relates to the annex of gasification burner, specifically be a kind of make fuel liquid and air from movingly with the device of conversion.

In the disclosed liquid fuel vaporizing burner, various informative, each has something to recommend him.The working method of its ignition and process have two kinds substantially: a kind ofly be, add the liquid fuel combustion heating in the outside of generating tube earlier, during to the vaporizing liquid that is enough to make through generating tube, just open fluid-delivery valve, make liquid fuel enter generating tube vaporization normal combustion afterwards; Another kind is, lighting valve and fluid-delivery valve are installed separately and operate, open lighting valve during use earlier, make liquid fuel and air export form of nozzle liquid cloud point fire burns to and heat generating tube through woven hose according to a certain ratio, when treating that generating tube is heated to the vaporizing liquid that makes process, close lighting valve, open fluid-delivery valve, the liquid of fluid-delivery valve output this moment normal combustion after the generating tube vaporization.Two kinds of gasification burners of above-mentioned introduction all exist to be needed between igniting and the normal combustion at interval, shortcomings such as operation inconvenience.

The utility model purpose is to provide that a kind of liquid gas is from movingly when realizing igniting in same device, and distribution is ended automatically during normal combustion, the new device of output liquid only, and making lights a fire to normal combustion does not need the substep operation.

The scheme that the utility model purpose realizes, it is the liquid feed device part of improving existing gasification burner, promptly be with the sleeve pipe that has certain interval between sealed at both ends, internal surface of sleeve pipe and the interior woven hose with the lower part leading to the interior woven hose 2～5cm of sealing in the steel cylinder, the sleeve pipe two ends respectively have an aperture, upper end air admission hole φ 1～1.5mm, lower end inlet opening φ 0.4～0.6mm, the interior woven hose lower end opening of splaying.When pouring into liquid fuel in the steel cylinder and being in barotropic state, open cylinder angle valve, this moment under pressure, liquid fuel in the steel cylinder in woven hose and the shell clearance is rapidly by interior woven hose emptying, simultaneously, gas in the steel cylinder and the liquid air admission hole from the sleeve pipe and inlet opening respectively replenish to enter and enter interior woven hose after mixing in the sleeve pipe, arrive the burner nozzle spray burning at last, and the heating generating tube.When generating tube is heated to when being enough to make the vaporizing liquid of process, because expanding, vaporizing liquid produces buffer brake, the output speed of liquid gas mixture slows down, and directly influenced the air inflow of air admission hole on the sleeve pipe, when arriving to a certain degree, a part of component sum of inlet opening hydraulic pressure is equal to or greater than the pressure of gas in the steel cylinder on the buffer brake of vaporized expanding and the sleeve pipe, and this moment, air admission hole stopped air inlet automatically.Because the pressure of inlet opening is still greater than the buffer brake of vaporized expanding, so feed flow still carries out continuously, guarantees flameholding.When flame-out, close angle valve, feed flow is ended, and enters liquid in the sleeve pipe and restores to the original state.

The size requirements of the round sleeve pipe of the utility model has the gap of 1.0～5.0mm behind the woven hose in it is inserted in, best clearance is 1～2mm.Simultaneously, the air admission hole on the sleeve pipe leaves opening apart from managing 1.0cm place, lower end for well apart from pipe 1.5cm place, top, inlet opening, exceeds air admission hole to avoid the liquid level in the steel cylinder.

After the utility model adopted such scheme, liquid gas was from movingly during igniting, and when igniting finished normal combustion, distribution was ended, and only converts to for liquid.This liquid gas is from not only easy and simple to handle, simple in structure with conversion equipment movingly, reliable operation, and also no matter in the steel cylinder how much pressure is arranged, liquid gas had significantly reduced the burning air consumption from movingly and conversion than general device when it can both realize lighting a fire.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the vertical section structural map of the utility model embodiment.

Among the figure 1, steel cylinder 2, sleeve pipe 3, interior woven hose 4, inlet opening 5, air admission hole 6, angle valve 7, woven hose 8, generating tube switch 9, generating tube 10, vaporizer 11, mixture pipe

In the drawings, an interior woven hose 3 is housed in the steel cylinder 1 in sealing and outside bottle outlet was extended at the steel cylinder top, angle was cut in interior woven hose 3 lower ends, and angle valve 6 is equipped with in the exit, upper end.Interior woven hose 3 upper end 2cm in the steel cylinder 1 are with sealed at both ends sleeve pipe 2 with the lower part, end 1.5cm in 2 times end distance steel cylinders of sleeve pipe, gap 1.0mm between sleeve pipe 2 inner tubal walls and the interior woven hose 3.The 1.5cm place has an air admission hole 5 apart from sleeve pipe 2 upper end, aperture φ 1.2mm; The 1.0cm place has an inlet opening 4 apart from sleeve pipe 2 lower end, aperture φ 0.5mm.During use, liquid level will be lower than more than the air admission hole 4cm in the steel cylinder.Angle valve 6 is connected with woven hose 7, and generating tube switch 8 is inserted in woven hose 7 other ends, generating tube switch 8 connection of connecting with generating tube 9, mixture pipe 11, vaporizer 10 again.
