Description

Vaporization unit {GASIFICATION DEVICE}

TECHNICAL FIELD This invention relates to the vaporization apparatus which heat-vaporizes and ejects liquid fuel, such as kerosene.

For example, the vaporization apparatus used for petroleum fuel equipment, such as a petroleum fan heater, and heating and vaporizing kerosene is generally the following structures.

A cylindrical vaporization section for heating and vaporizing liquid fuel (kerosene) and a vaporized gas vaporized by communicating with the vaporization section and ejecting the vaporized gas vaporized at the vaporization section from the outlet of the tip and ignited by the burner. It consists of a cylindrical nozzle part to combust, The said vaporization part installs the inner pipe which the said liquid fuel is supplied from a base end part in the inside of a cylindrical heating element, for example, and makes it a front end vaporization chamber, The tubular heating element is housed in a housing tube, and an outer tube communicating with the inner tube and the distal end portion is further provided on the outer side of the housing tube to vaporize the shear inside the outer tube, that is, between the outer tube and the housing tube. It is set as the rear | end stage vaporization chamber which communicates with a thread, and the communication port which communicates with the said nozzle part is provided in the downstream of this rear-end vaporization chamber.

On the other hand, the nozzle portion is provided with the nozzle at the distal end of the cylindrical nozzle body portion communicating with the communication port and at the proximal end, and installs a movable piece that moves forward and backward in the nozzle body portion by the solenoid. The valve rod which opens and closes the said injection port is provided in the front-end | tip of this movable piece, and it is resisted by the blockage bias by an elastic body from the state which closed the injection port by the opening-and-closing needle valve of the front end of a valve rod, As a result, the movable piece is moved to the proximal end, the valve rod is retracted to open the ejection port, and the vaporized gas is ejected.

Conventionally, in the vaporization portion of the vaporization device, a shallow groove on the inner surface of the inner tube in order to increase the heat transfer area of the inner surface of the inner tube to prevent the hopping phenomenon caused by film boiling of kerosene to generate a stable vaporized gas. To increase the contact area with kerosene and to maintain the kerosene retention.

However, when kerosene inflows such as petroleum fan heaters for business use are large, the heat transfer area and the contact area of kerosene are insufficient in shallow grooves, and the residence time of kerosene is short. As a result, the heat conduction to kerosene is not performed completely. The temperature rose excessively, and there was a problem in the generation of stable vaporized gas and the heat resistance of the inner tube.

In addition to the problem of the shear vaporization chamber inside the inner tube, the kerosene does not evaporate stably without excessive heat transfer from the heating element or its storage tube even in the rear vaporization chamber inside the outer tube. Increasing the area also causes problems such as clogging due to tar.

To explain further, for example, kerosene generally causes various defects because its own vapor causes film boiling between the inner surface of the inner tube and the kerosene.

For example, kerosene vaporizes at the shortest time when it is about 250 ° C, but when it reaches a higher temperature, evaporation time is gradually longer, and film boiling becomes remarkable at about 300 ° C or more, and the vaporization time is considerably longer. If the vaporization portion is inclined, oil droplets roll over and fall, causing a hopping phenomenon, and the vaporization is not stabilized, and pulsation combustion occurs.

The present invention solves this problem, and greatly increases the heat transfer area and the contact area of the inner tube inner surface of the shear vaporization chamber with a simple configuration, and sufficiently retains liquid fuel such as kerosene to prevent excessive temperature rise in the inner tube. Stable vaporization gas can be generated efficiently, and even in the rear vaporization chamber inside the exterior, it can be easily partitioned into small passages without tar clogging to transmit heat efficiently and uniformly. It is an object of the present invention to provide an excellent vaporization apparatus, such as being capable of heating and increasing the temperature instantaneously and enabling stable ignition.

It is sent to the downstream vaporization chamber (8) which is bent at the tip and communicates with it.

For example, the inner tube 5 is disposed inside the tubular heating element 4, and the inner tube 5 is heated by the tubular heating element 4, but the inner surface of the inner tube 5 is, for example, an example. For example, since the sintered wire mesh 13 sintered the cylindrical wire mesh is inserted and arranged, the heat transfer area is drastically increased, and the heat transfer to the liquid fuel is performed satisfactorily, and the temperature of the inner tube 5 rises excessively. It is also prevented, and since it is mesh-shaped, the contact area with a liquid fuel increases, and it catches and hold | maintains a liquid fuel favorably, and generation of stable vaporization gas is performed.

Therefore, the vaporized gas and the unfueled liquid fuel do not pass through a meandering passage, but are blocked by tar because they pass through a small elongated passage having a tubular length and a sufficient cross-sectional area. In addition, since the rear end vaporization chamber 8 is formed in a number of compartments in the elongated small passage, it becomes uniform and efficiently transferred to realize a more stable supply of the vaporized gas.

The ring-shaped restraint member 18 can be provided to be movable along the inner tube 5, or the portion that restrains the tubular heating element 4 to the ring-shaped restraint member 18 is movable. By providing the follow-up movable part 19, the movement of the cylindrical heating element 4 resulting from the difference of the thermal expansion rate of each part is absorbed, and the breaking of this ring-shaped restraint member 18 can be prevented.

Moreover, the nozzle part 2 which communicates with this vaporization part 1 and blows off the vaporization gas heated at this vaporization part 1 from the injection port 3 of a front end part communicates with the said communication port 9 At the tip end of the nozzle main body, the nozzle 3 is provided at the tip and at the same time the solenoid 10 is arranged at the proximal end, and the solenoid 10 is moved forward and backward in the nozzle body.
