Abstract

The utility model discloses a dual-cyclone gas burner, belongs to a gas burner and particularly relates to a gas burner in which at least one gas does cyclone motion, and the gas burner does not perform premixing. The dual-cyclone gas burner comprises a burner shell, a fuel gas inlet, an air inlet, sight glass sleeve, a flame detection port, a long open fire port, an ignition port and a flame detection port; the structure of the dual-cyclone gas burner is that an external air chamber between the shell and the external wall of a fuel gas sleeve is internally provided with an external cyclone sheet; an internal air chamber between the internal wall of the fuel gas sleeve and the sight glass sleeve is provided with an internal cyclone sheet; a gas-distributing plate with small holes is arranged at the front end of the fuel gas sleeve; and gas-distributing branch sleeves connected with the internal and external air chambers are arranged on the fuel gas sleeve. As the internal and external cyclone sheets with opposite rotation directions, and the sight glass sleeve with the front end expanding outwards are adopted, two airflows entering a furnace form strong rotational disturbance at the outer side and inner side of a fuel gas flow, and the fuel gas flow can be mixed with the airflows quickly; therefore, the effects of rapid burning velocity, short flame length and concentrated heating power can be achieved.

Description

Bispin streaming gas burner

Technical field

The utility model belongs to gas burner, and particularly at least a gas is done the gas burner of the not premix of swirling motion.

Background technology

Gas burner, being widely used in the combustion gas is the equipment such as various heating furnaces, boiler, kiln of the energy, the combustion system of gas burner mainly is divided into premixed and exterior mixing two classes, traditional exterior mixing burner is that the air velocity difference when utilizing combustion gas and air to introduce causes local eddy current, burns while mix, because mixing velocity is slow, so will grow burning time relatively, so the length of flame is big, heating power is not concentrated, and efficiency of combustion is low.

The utility model content

In order to overcome the deficiency that existing exterior mixing gas burner mixing velocity is slow, burning time is long, efficiency of combustion is low, the utility model provides a kind of bispin streaming gas burner, this bispin streaming gas burner has improved mixed gas speed, and combustion flame is short, the thermal efficiency is high.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of bispin streaming gas burner, comprise burner housing, be installed in the fuel gas inlet on the shell, air intlet, the visor sleeve pipe, flame detects mouth, burner kept burning day and night, lighting-up tuyere, flame detects mouth, it is characterized in that: spinning disk outside being equipped with in the outer space air cavity between shell and gas sleeve outer wall, air chamber is equipped with interior spinning disk between gas sleeve inwall and the visor sleeve pipe, the gas sleeve front end is equipped with the air distribution disk that has aperture, and gas sleeve is provided with the branch gas branch pipe that connects the inner air and outer air chamber.

Described visor sleeve pipe front end is the taper shape that expands outwardly.

Spinning disk is opposite with the direction of rotation of outer spinning disk in described.

The beneficial effects of the utility model are because burner is provided with the opposite inside and outside spinning disk of direction of rotation and front end is that the visor sleeve pipe that extends out broadening formation can make two strands of air streams that enter in the stove form strong rotation disturbance in the inside and outside both sides of gas-flow, make mixing that gas-flow can be very fast with it, burning velocity is fast, the length of flame short thereby reached, the effect that heating power is concentrated, promoting the use of of this burner, help energy-saving and emission-reduction, good economy and environmental benefit are arranged.

Description of drawings

Fig. 1 is a structural representation of the present utility model,

Among the figure, 1. combustion liner, 2. air distribution disk, 3. visor sleeve pipe, 4. in spinning disk, 5. outer spinning disk, 6. mounting flange, 7. shell, 8. minute gas branch pipe, 9. fuel gas inlet, 10. lighting-up tuyere, 11. visor mouths, 12. burners kept burning day and night, 13. flames detect mouth, 14. air intlets.

The specific embodiment

The specific embodiment of the present utility model is, as shown in the figure:

Embodiment 1, a kind of bispin streaming gas burner, the fuel gas inlet 9, air intlet 14, visor sleeve pipe 3, the flame that comprise burner housing 7, be installed on the shell detect mouth 13, burner kept burning day and night 12, lighting-up tuyere 10, it is characterized in that: spinning disk 5 outside being equipped with in the outer space air cavity between shell and gas sleeve outer wall, spinning disk 4 in air chamber is equipped with between gas sleeve inwall and the visor sleeve pipe, the gas sleeve front end is equipped with the air distribution disk 2 that has aperture, and gas sleeve is provided with the branch gas branch pipe 8 that connects the inner air and outer air chamber.

Embodiment 2, a kind of bispin streaming gas burner, comprise burner housing 7, be installed in the fuel gas inlet 9 on the shell, air intlet 14, visor sleeve pipe 3, flame detects mouth 13, burner 12 kept burning day and night, lighting-up tuyere 10, it is characterized in that: spinning disk 5 outside being equipped with in the outer space air cavity between shell and gas sleeve outer wall, spinning disk 4 in air chamber is equipped with between gas sleeve inwall and the visor sleeve pipe, the gas sleeve front end is equipped with the air distribution disk 2 that has aperture, gas sleeve is provided with the branch gas branch pipe 8 that connects the inner air and outer air chamber, visor sleeve pipe front end is the taper shape that expands outwardly, and the rear end is a visor mouth 11.

Operation principle of the present utility model is that fuel gas enters burner by import, spray in the stove through the air distribution disk fumarole along combustion liner, air by air intlet enter along enclosure interior air exocoel through outside spinning disk enter in the stove, part combustion air enters inner chamber by four small-bore minute gas branch pipes 8, the visor sleeve pipe front end of inner chamber is the taper shape that expands outwardly, make the internal air stream attenuation, spinning disk entered in the stove in the circulation of air of raising flow velocity was crossed, because the rotation direction of inside and outside spinning disk is opposite, so that two strands of air streams that enter in the stove form strong rotation disturbance in the inside and outside both sides of gas-flow, make mixing that gas-flow can be very fast with it, thereby it is fast to have reached burning velocity, the length of flame is short, the purpose that heating power is concentrated, while, the coefficient of excess that can reduce air was that sufficient combustion reaches purpose of energy saving again owing to the gas mixing is good.

Claims

1. bispin streaming gas burner, the fuel gas inlet, air intlet, visor sleeve pipe, the flame that comprise burner housing, be installed on the shell detect mouth, burner kept burning day and night, lighting-up tuyere, flame detection mouth, it is characterized in that: spinning disk outside being equipped with in the outer space air cavity between shell and gas sleeve outer wall, air chamber is equipped with interior spinning disk between gas sleeve inwall and the visor sleeve pipe, the gas sleeve front end is equipped with the air distribution disk that has aperture, and gas sleeve is provided with the branch gas branch pipe that connects the inner air and outer air chamber.
