Description

Technical Field

[0001] The utility model relates to the technical field of gas-fired thermal power generation, and particularly relates to a rotary-core catalytic burner. Background Art

[0002] At present, gas-fired thermal power generation usually directly inputs air and gas into the combustion chamber to be ignited. Since the air and gas pipelines are set separately and there is no relevant setting for mutual mixing, they only flow and mix naturally in the combustion chamber. Therefore, the combustion mixture ratio of the gas is unstable, directly affecting the stability of the length of the formed flame. In addition, since the gas inlet pipes usually need to be set at multiple angles around the combustion chamber, the air inlet direction of each gas pipe is fixed, and a "W"-shaped flame combustion mode needs to be formed. However, due to the insufficient stability of the flame length, the efficiency of gas-fired thermal power generation is generally low. Content of the Utility Model

[0051] The working principle of the present utility model is as follows:

[0052] As shown by Figures 1 to 19 , the provided squirrel-cage sleeve includes a first fixing block 141 and a second fixing block 143 communicated with the air guide hole 27. A plurality of support plates 144 are connected between the two fixing blocks, and air vent holes 145 are provided on the side walls of each support plate 144; in this way, while rotating with the transmission shaft 2, gas can also enter the air guide hole 27; before use, in order to prevent gas from leaking out from the connection gap between the sleeve 13 and the connecting sleeve 141 and the first fixing sleeve 142 into the air cylinder 1, and to avoid the ignition needle 53 igniting the gas leaking out of the air cylinder 1 with negative-pressure air after ignition, the negative-pressure air damper 12 should be opened first to introduce air into the air cylinder 1. The introduced air carries the residual gas in the air cylinder 1 and then discharges from the third air outlet pipe 43. After the negative-pressure air damper 12 is opened for a period of time (on the premise of ensuring no gas residue and introducing gas to meet the capacity of the air cylinder 1), the gas inlet pipe 10 is opened to discharge gas. The gas enters the air guide hole 27 through the connection hole of the second fixing block 143 via the sleeve 13, and finally discharges through the conical hole (261. While discharging, due to flowing through a plurality of spiral air channels 262 arranged along the circumferential direction (such as Figure 17 the state shown), the gas forms a spiral shape in the gas outlet direction.

[0053] Meanwhile, the pneumatic motor 3 also needs to be turned on. The driving gear 25 connected to the output end synchronously drives the driving gear 20 and the transmission shaft 2 to rotate. The transmission shaft 2 then drives the four planetary gears 162 meshingly connected to the central gear 18 to rotate meshingly on the internal gear disk 161. The rotation of the planetary gears 162 drives the boss 40 and the air flow distribution sleeve 4 to rotate simultaneously by the first air outlet pipe 41. Since the second air outlet pipe 42 is also arranged through the planetary gear disk 17 sleeved on the transmission shaft 2, the second air outlet pipe 42 and the first air outlet pipe 41 are in a synchronous rotation state.

[0054] Under the condition of rotational startup, the air discharged from the pneumatic motor 3 flows through the exhaust pipe 30 to the annular air cylinder 31, and then enters the annular through groove formed by enclosing the inner side wall of the internal gear disk 161 by the ventilation groove 401 through a plurality of branch air pipes 32 connected in the circumferential direction. Finally, it enters the hollow position of the boss 40 from the air hole 402 and discharges from the four first air outlet pipes 41 and the four second air outlet pipes 42 connected and penetrated in the circumferential direction on the side wall of one side of the boss 40; the gas discharged from the air cylinder 1 through the third air outlet pipe 43 is discharged through the position of the arc-shaped through hole 171.

[0055] Among them, the air discharged through the first air outlet pipe 41 passes through the first cavity 51 in the first air generator 5 and is discharged from the positions of the rotating first guiding groove 61 and the rotating air-permeable holes 502, also forming a spiral air outlet form, and is mixed with the spirally discharged fuel gas; at the same time, the air discharged through the second air outlet pipe 42 passes through the second cavity 52 in the second air generator 5 and is simultaneously output from the positions of the air-dispersing holes 53 and the exhaust holes 71, and is discharged at the position of the rotating second guiding groove 62, thereby forming a double-layer spiral air outlet form, and then is preliminarily mixed with the spirally discharged fuel gas and the air spirally discharged from the first guiding groove 61 in the flame stabilizing cover 19. Since the mixing disk 8 is screwed to the nozzle 26, the nozzle 26 is sleeved on the transmission shaft 2 and rotates synchronously with the transmission shaft 2, that is, the preliminarily mixed gas is finally fully mixed through the mixing through holes 83 on the rotating mixing disk 8. All the air outlet positions form a spiral air outlet state. At the same time, the air outlet angle of the first guiding groove 61 is 75°, the exhaust angle of the exhaust hole 71 is 45°, and the air outlet angle of the air-dispersing hole 53 is 20°, so as to facilitate the simultaneous rotation and diffusion of the gas and the rotation and mixing, and improve the mixing efficiency; in order to make the combustion ratio of the fuel gas to the air reach the ratio of 1:10, in addition, the air in the air cylinder 1 discharged through the third air outlet pipe 43 passes through the rotating arc-shaped through hole (171 (the planetary gear disk 17 rotates with the transmission shaft 2) and is discharged, which can make up for the lack of air supply volume of the pneumatic motor 3.

[0056] Finally, the ignition needle 54 ignites the mixed fuel gas; when it is necessary to adjust the flame spraying angle, the reciprocating motor 91 is started to drive the fixed block 93 to horizontally move along the axial direction of the lead screw 92, and drive the hinged rocker 94 to rotate, and synchronously drive the air cylinder 1 hinged to the other end of the rocker 94 to start to turn over. The internal gear disk 161 is connected to the air cylinder, and a ring sleeve 95 is sleeved on the outside of the internal gear disk 161. A flange sleeve 96 is also sleeved on the outside of the ring sleeve 95. The hole walls at the left and right ends of the middle hole of the flange sleeve 96 are adaptively abutted against the outer side walls at the corresponding positions of the ring sleeve 95, so that the ring sleeve 95 can turn over in the front and rear directions in the middle hole of the flange sleeve 96. Therefore, in the rotating state of the rocker 94, the air cylinder 1 and the whole cyclone device are driven to turn over in the front and rear directions (that is, make a clockwise or counterclockwise turn in the vertical direction shown in Figure 1 ).

[0057] In addition, when it is necessary to adjust the gas displacement, in addition to twisting the shield body 81 before use to adjust the length of the tapered block 82 extending into the tapered hole 261, the electric jack 11 can also be started after ignition, and the ball head 151 and the transmission shaft 2 are synchronously driven by the support rod 15 to move in the horizontal direction to adjust the gap between the hole wall of the tapered hole 261 and the outer side wall of the tapered block 82, so as to realize the adjustment of the gas exhaust volume; among them, since the driving gear 20 and the driven gear 25 are in a straight-tooth meshing state, and the air flow distribution sleeve 4 is internally provided with a bearing 21 sleeved on the outer side of the transmission shaft 2, there will be no interference between the longitudinal rotation of the transmission shaft 2 and the use state of the axial translation.

[0058] However, at the same time, there is always an overlapping influence of certain cross stresses in the actions in both directions, which causes wear on the outer wall of the transmission shaft 2. In order to compensate for the use wear and ensure the stability of the longitudinal and axial movements, a support sleeve 43 fixedly screwed to the air cylinder 1 is provided on the outer side of the air flow distribution sleeve 4. A second connecting ring 44 is provided in the middle of the support sleeve 43. An installation sleeve is sleeved on the side wall of the second connecting ring 44. A second fixing sleeve 45 is sleeved in the installation sleeve. A stepped hole is provided on the second fixing sleeve 45. An object placing cylinder 46 is inserted into the large hole end of the stepped hole. A roller 47 is provided in the object placing cylinder 46. One end of a compression spring 48 abuts against the bottom of the small hole end of the stepped hole, and the other end of the compression spring 48 abuts against one side of a lubricating block 49. The other side of the lubricating block 49 abuts against one side of the roller 47. The other side of the roller 47 protrudes out of the object placing cylinder 46, and the protruding end of the roller 47 is abutted against the outer side wall of the air flow distribution sleeve 4. In this way, an elastic support state between the support sleeve 43 and the transmission shaft 2 is realized. As the transmission shaft 2 wears, the roller 47 continuously protrudes under the elastic force of the compression spring 48 to abut against the transmission shaft 2 until the protruding end of the roller 47 reaches the limit position and no longer abuts against the worn transmission shaft 2. When the transmission shaft 2 has an abnormal use, it can be disassembled and replaced in time.

[0059] In order to limit the horizontal movement distance of the transmission shaft 2, a limiting groove 164 is provided on the inner side wall of the internal gear disc 161 corresponding to the position of the ventilation groove 401, and the outer edge of the convex platform 40 extends into the limiting groove 164. Since the air flow distribution sleeve 4 and the driving gear 20 are axially connected by a thrust ball bearing 23, and the driving gear 20 is screwed to a fixing ring 22 sleeved on the transmission shaft 2, and the air flow distribution sleeve 4 is internally provided with a bearing 21 sleeved on the outer side of the transmission shaft 2, when the outer side wall of the convex platform 40 abuts against the groove wall of the limiting groove 164, the movement limit of the transmission shaft 2 is realized.

[0060] In addition, in order to prevent ignition failure, a flame sensing needle 191 is further provided inside the flame stabilizing cover 19, and the component (not labeled) connected to the flame sensing needle 191 is arranged outside the air cylinder 1 for easy observation. In case of ignition failure or insufficient flame length, the aforementioned operations for adjusting the gas displacement can be started in a timely manner; the component connected to the flame sensing needle 191 and its installation state are both prior arts, and the relevant content will not be elaborated here.
