Embodiment 1

[0018] Embodiment 1, a multi-stage continuous auxiliary heat energy-saving device for a dimethyl ether gas-fired boiler burner, such as figure 1 As shown, including the auxiliary heat cylinder 1, the auxiliary heat cylinder 1 is docked with the flame injection tube of the burner, the flame of the flame injection tube will protrude along the auxiliary heat cylinder 1, then the inner wall of the auxiliary heat cylinder 1 will be completely covered by the flame, and the auxiliary heat cylinder 1 will be completely covered by the flame. The flame in the heat cylinder 1 will gradually heat the auxiliary heat cylinder 1 to a high temperature of 800 degrees Celsius.

[0019] A bracket 2 is arranged inside the auxiliary heat cylinder 1 , and a rotating impeller 3 is connected to the bracket 2 , and the blades 31 of the rotating impeller 3 are arranged obliquely relative to the central axis of the auxiliary heat cylinder 1 . The rotating impeller 3 can not only block the flame and make...

Embodiment 2

[0023] Example 2, multi-stage continuous auxiliary heat energy-saving device for dimethyl ether gas boiler burner, the water supply pump is connected to a controller, and a solenoid valve connected to the controller is provided between the pump water port of the water supply pump and the high temperature resistant pipe 4 , the solenoid valve is connected to a controller through a timer, and the controller is connected to a temperature sensor for monitoring the temperature of the auxiliary heat cylinder 1 . The controller controls the working state of the solenoid valve according to the real-time temperature detected by the temperature sensor, and then controls the working state of the high-temperature-resistant atomizing nozzle 5 in real time.

[0024] Only when the temperature reaches 800 degrees Celsius and the timer reaches the opening time of the solenoid valve, the controller controls the solenoid valve to open, and the high temperature resistant atomizing nozzle sprays wa...

Embodiment 3

[0026] Embodiment 3, a multi-stage continuous auxiliary heat energy-saving device for a dimethyl ether gas-fired boiler burner. The high-temperature-resistant atomizing nozzles 5 are arranged at intervals in a ring along the circumference of the central rod 22, which can make the spraying of water mist more uniform and make the lanthanum oxide The amount converted to lanthanum hydroxide is more sufficient.

[0027] If the inclination angle between the blades 31 and the central axis of the auxiliary heat cylinder 1 is too large, the blades 31 will not rotate; It will not produce too much resistance to the flame, and can rotate with it.

[0028] Other structures of this embodiment are the same as Embodiment 1 or 2.

Abstract

The invention discloses a multistage continuous auxiliary heating energy saving device of a dimethyl ether gas-fired boiler combustor and application of the multistage continuous auxiliary heating energy saving device. The multistage continuous auxiliary heating energy saving device comprises an auxiliary heating barrel, and the auxiliary heating barrel is in butt joint with a flame spraying pipeof the combustor. A support is arranged in the auxiliary heating barrel, and the support is connected with a rotary impeller. The support comprises a radial rod arranged in the auxiliary heating barrel in the radial direction, and the radial rod is connected with a center rod. The rotary impeller is rotationally arranged on the center rod. A water storage cavity is formed in the center rod, and ahigh temperature resisting pipe connected with the water storage cavity is arranged. The high temperature resisting pipe is connected with a water supply pump, and high temperature resisting atomizingspray heads connected with the water storage cavity are arranged on the periphery of the center rod. Lanthanum oxide layers and palladium layers are arranged on the outer wall of the radial rod, thesurfaces of blades and the inner wall of the auxiliary heating barrel. According to the multistage continuous auxiliary heating energy saving device, lanthanum oxide is converted into lanthanum hydroxide to release heat, auxiliary heating is carried out on combustion of dimethyl ether fuel gas, spray can be decomposed into hydrogen and oxygen by palladium at the high temperature of 800 DEG C, thecombustion efficiency of the dimethyl ether fuel gas can be effectively enhanced through the oxygen, and the hydrogen can be used for combustion to enhance the combustion heat value of the dimethyl ether fuel gas.

Description

technical field [0001] The invention relates to the technical field of dimethyl ether combustion, in particular to a multi-stage continuous auxiliary heat energy-saving device for a dimethyl ether gas boiler burner and its application. Background technique [0002] Dimethyl ether has the main properties of fuel, its calorific value is about 64.686MJ / m³, and its own oxygen content is 34.8%. It is an ideal clean fuel because it can be fully burned, without carbon precipitation, and without residual liquid. , but the relative calorific value of dimethyl ether is low, how to improve the combustion efficiency of dimethyl ether, how to achieve a better effect of environmental protection and energy saving is the direction of research. At a high temperature of 800 degrees Celsius, lanthanum oxide will be transformed into lanthanum hydroxide in contact with water, and a large amount of heat will be generated during the conversion of lanthanum oxide into lanthanum hydroxide. This heat...
