detailed description

The present invention will be further described below in conjunction with accompanying drawing.

Fig. 1 is a schematic structural view of an alcohol combustion device in Example 1 of the present invention; as shown in Fig. 1 , the present invention provides a kind of alcohol combustion device, comprising a combustion chamber 1, and a burner is arranged inside the combustion chamber 1 2. The combustion chamber 1 includes an inner chamber 11 for placing the burner 2 and an outer chamber 12 for placing fuel. The outer chamber 12 is arranged around the inner chamber 11. An inspection port 5 is provided at the end of the combustion chamber 1 for inspection. Port 5 is provided with a sealing valve 6 .

The combustion chamber 1 can be in various shapes, such as cuboid. Preferably, the combustion chamber 1 is cylindrical, and the combustion chamber 1 is arranged horizontally. The inner cavity 11 is cylindrical, and the outer cavity 12 is circular (as shown in FIG. 2 ). The outer cavity 12 is used to hold liquid fuel, the inner cavity 11 is used to place the burner 2, and the inside of the burner 2 is used to introduce gaseous fuel to separate the liquid fuel from the gaseous fuel, thus avoiding gas and liquid mixing during combustion And lead to the occurrence of safety accidents such as explosions, improve the safety of use.

Wherein, the burner 2 is constructed in a tubular shape, and its interior is a chamber for containing gaseous fuel; holes; the two ends of the burner 2 are the fire end 22 and the air intake end 23 respectively.

Therefore, when gaseous fuel passes through the burner 2, flames are ejected through the flame port 21 on the side wall and the outer cavity 12 is heated, and the inside of the outer cavity 12 is provided with a heat conductor 13, so the heat can be evenly transferred The liquid fuel entering the outer chamber 12 is heated to vaporize the liquid fuel, and the vaporized gas fuel circulates in the combustion chamber 1 and enters the burner 2 . Therefore, the utilization rate of heat in the combustion process can be improved, thereby improving the combustion efficiency and reducing the cost of use.

In order to heat the liquid fuel in the outer cavity 12 more fully, a plurality of heat conductors 13 are arranged inside the outer cavity 12 , and a plurality of convex tubes 14 are arranged in the inner cavity 11 , and the convex tubes 14 communicate with the outer cavity 12 .

Further, the heat conductors 13 are equally spaced along the axis of the outer cavity 12 , and can transfer heat evenly when the outer cavity 12 is heated. As shown in FIG. 2 , one end of the heat conductor 13 is connected to the side wall of the outer cavity 12 , and a gap is provided between the other end and the side wall of the outer cavity 12 to ensure the normal circulation of liquid in the outer cavity 12 .

The gas methanol entering the burner 2 is ignited and burned at the flame port 24, thereby continuing to heat the outer cavity 12, so that it continuously generates gas methanol.

Therefore, through the above-mentioned method, that is, while burning methanol, the liquid methanol is heated to generate gaseous methanol, so that the whole process forms an organic cycle, and the heat generated in the combustion is also used, so there is no need to use other equipment to process the liquid methanol. It is heated, thus greatly improving its combustion efficiency and reducing the cost of use.

In this embodiment, a liquid level sensor 31 is disposed in the liquid inlet 3 . The liquid fuel content in the liquid inlet 3 and the outer cavity 12 can be measured by the liquid level sensor 31.
