Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen-rich fuels, and in particular to a control method for hydrogen-rich combustion. Background Art

[0002] Hydrogen-rich fuels can be divided into three categories according to their sources: coke oven gas, refinery gas, and syngas. Coke oven gas contains hydrogen and nitrogen, and the hydrogen volume fraction in refinery gas is as high as 90%. The hydrogen volume fraction in syngas can be as high as 50%. Since there are many sources of refinery gas and syngas in small factories everywhere, coke oven gas needs to be treated before reuse.

[0003] In the prior art, hydrogen-rich fuels are transported through multiple main pipelines and transported into a target device to burn in cooperation with oxygen. The laying of multiple main pipelines not only occupies a large space, but also is more cumbersome to maintain, and the setting of multiple main pipelines will also increase the procurement cost. Moreover, when the hydrogen-rich gas fuel transported into the target device through multiple main pipelines is mixed with oxygen, the two often mix insufficiently due to too fast transportation speed and lack of stirring equipment, thus affecting its subsequent combustion.

The regulating block 34 is driven to rotate by the motor 13 connected to the main pipeline 1, and the outlet of the air outlet channel 35 is adjusted to be connected to one of the first connecting pipes 5 and sent into the corresponding stirring tank 2.

The transmission shaft 6 can drive the first gear 7 to rotate by means of the rotating shaft 18. The first gear 7 can drive the linkage shaft to rotate by means of the second gear 8 meshing with it. The linkage shaft can drive the reciprocating lead screw 23 to rotate by means of the third gear 24 and the fourth gear 25. When the reciprocating lead screw 23 rotates, the lead screw sleeve 27 on its outer wall can drive the piston plate 26 to move reciprocally in the air pumping cavity 22 by means of the connecting rod. At this time, the suction pipe 15 (equipped with an intake one-way valve) connected to the air pumping tank 9 sucks oxygen into the air pumping tank 9, and then sends the oxygen into the regulating tank 10 by means of the second connecting pipe 12 (equipped with an outlet one-way valve). At this time, the regulating block 34 in the regulating tank 10 is also adjusted to rotate the regulating box by the motor 13, so that the outlet of the air outlet channel 35 on the regulating block 34 corresponds to one of the intake pipes 4, and the oxygen is sent into the stirring tank 2. When the hydrogen-rich gas fuel and oxygen enter the stirring tank 2, they will press down the movable plug 28. When the movable plug 28 moves, it can also drive the rotating rod 29 to rotate by means of the screw 31. The rotation can drive the stirring rod 30 to rotate to realize the stirring and mixing treatment of the gas. Finally, the state of the movable plug 28 is as Figure 5 shown. At this time, the mixed gas is discharged through the discharge pipe 3 and enters the target device for combustion.
