Description

[Detailed explanation of the idea] The present invention relates to a vaporizer for an oil combustor.

Conventionally, as a vaporizer for an oil combustor, for example, as shown in FIGS. 1 and 2, a heating chamber C is provided between an intermediate cylinder a and an outer cylinder.
At the same time, a heater chamber f containing a heater e is formed between the intermediate cylinder a and the inner cylinder Md, and the inner cylinder d and the heating chamber C communicate with each other through a through hole g at one end. Oil supplied from the other end of d is preheated in cylinder d and supplied into heating chamber C,
The structure is such that vaporized gas is injected from the injection pipe i through a hole provided in the upper part of the outer cylinder and supplied to the burner mixing pipe.
8176).

This is an excellent device that can be formed compactly and performs vaporization relatively efficiently, but especially when the flow rate is large because preheating is performed in the inner cylinder d, the heat absorption in the inner cylinder d is large and the heating The temperature inside the chamber C decreases, and sufficient heating is not possible, and complete vaporization is not performed.In addition, when two or more injection pipes i, i are provided in the outer cylinder, the upstream and downstream of the flow There were drawbacks such as the heating temperature being different and the flame size of the burner being different.

The purpose of the present invention is to provide a vaporizer free from such drawbacks, in which a heating chamber 1 is formed by inner and outer cylinders 2 and 3 that are spaced apart, and an electric heater 4 is installed in the inner cylinder 2. accommodate,
The lower part of the outer cylinder 3 is covered with a semi-cylindrical member 5 to form a preheating chamber 6 between the semi-cylindrical member 5 and the outer cylinder 3, and the semi-cylindrical member 5
A fuel supply hole 7 is provided at the center of the lower part of the outer cylinder 3, and a pair of communication holes 8, 8 are provided symmetrically on both sides of the lower part of the outer cylinder 3, and the injection pipe 9 is connected to the upper center of the outer cylinder 3 or at a symmetrical position thereof. A discharge port 10 is provided.

In the case shown in FIGS. 3 to 5, there is a
The valve housing 11 of the solenoid valve 11 is provided with three discharge ports 10 and
It was opened at a.

The valve housing 11a has a solenoid body 1 provided therein.
It has a valve body 11d connected to a mover 11c housed in a movable body 1b, and a valve seat 11f having a valve hole 11e facing thereto. It is connected to each injection pipe 9 via.

Each injection pipe 9 has a tip nozzle 9a, a solenoid body 9b in the injection pipe 9, a movable element 9c housed in the solenoid body 9b, and a cleaning pin 9 of the nozzle 9a connected thereto.
d and each nozzle 9a.

9a are opposed to the mixing tubes 13a of the burner 18, respectively.

The electric heater 4 housed in the inner cylinder 2 is a sheathed heater wound in a coil shape to facilitate its attachment and detachment.

Thus, when the heating chamber 1 and the preheating chamber 9 are heated by the electric heater 4, power is supplied to the solenoid body 11b, the valve body 11d is moved back, the valve hole 11e is opened, and the preheating chamber 6 is opened from the oil supply hole T. The oil supplied into the heating chamber 1 flows in two directions, is preheated, flows into the heating chamber 1 through the communication hole 8°8, rises while vaporizing within the heating chamber 1, and merges through the discharge port 11. The vaporized gas is supplied into the valve housing 11a through the valve hole 11e, and is supplied to each injection pipe 9, 9 via the branch pipe 12.12, and is injected from each nozzle 9a, into the mixing pipe 13a.
, 13a to the burners 13, 13 for ignition.

In this way, oil supplied from the oil supply hole 1 is preheated in the lower part of the heating chamber 1, then supplied into the heating chamber 1, and as it ascends through the heating chamber 1, it is sufficiently heated and vaporized and flows out from the discharge hole 10. Therefore, preheating in the preheating chamber 6 does not affect the heating chamber 1.

In this embodiment, a case is shown in which one discharge port 10 is provided at the center of the upper part of the heating chamber 1, but when a pair of discharge ports is provided symmetrically, the left and right channels are symmetrical. Therefore, no temperature difference occurs in the vaporized gas flowing out from each discharge port.

Further, the solenoid body 9b is configured to, for example, start combustion.
When the power switch is turned on, it operates intermittently several times to move the cleaning pin 9d back and forth to clean the nozzle 9a, thereby preventing its clogging.

Then, while the burners 13 and 130 are ignited, electricity is maintained and the retracted position is maintained.

In this way, according to the present invention, the lower part of the heating chamber 1 formed by the inner and outer cylinders 2 and 3 is covered with the semi-cylindrical member 5 to form the preheating chamber 6, and the oil supplied from the center of the lower part of the preheating chamber 6 is preheated. The inside of the chamber 6 is divided to the left and right, preheated and supplied into the heating chamber 1 through the communicating holes 8, 8 on both sides, and the mixture is merged in the center of the heating chamber 1 and flows out from the common discharge port 10, or Since it was made to flow out from the discharge ports 10, 10 provided at symmetrical positions,
Like the conventional vaporizer described above, heating chamber 1 is heated by preheating.
It does not affect the heating inside the tank, and the oil can always be sufficiently vaporized and a stable flame can be obtained. Obtaining flames has the effect of improving performance.
