Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

The first embodiment is as follows:

referring to fig. 1-3, a self-smoke-removing type boiler tail gas discharge pipeline comprises an exhaust pipe 1 and is characterized in that an arc-shaped groove 2 is formed in the side wall of the exhaust pipe 1, a glass cylinder 3 is fixedly connected in the arc-shaped groove 2, a silicon steel sheet 5 is arranged in the glass cylinder 3, and a silk layer 51 is arranged on the side wall of the silicon steel sheet 5. And silicon steel sheet 5 rotates through spring shaft 6 and connects in glass section of thick bamboo 3, and glass section of thick bamboo 3 overcoat is equipped with drum 4, and drum 4 rotates and connects on the inner wall of arc wall 2, and a plurality of through-holes 41 have been seted up to the lateral wall of drum 4.

It should be noted that, as shown in fig. 3, the silk layer 51 is only disposed on a portion of the side wall of the silicon steel sheet 5 near the inside of the exhaust pipe 1, so as to ensure that static electricity is only formed on a portion of the side wall of the glass cylinder 3 inside the exhaust pipe 1, on one hand, the side wall of the glass cylinder 3 outside the exhaust pipe 1 is prevented from adsorbing dust in the air, which affects the use effect of the device; on the other hand, when the through hole 41 pushes the dust out of the exhaust pipe 1, the dust can be easily dropped off.

Further, by arranging the cylinder 4 with the through holes 41, on one hand, the through holes 41 can block the tail gas flow so as to prevent the flowing tail gas from blowing off the smoke dust adsorbed on the outer wall of the glass cylinder 3; on the other hand, because the circumference lateral wall of drum 4 closely presses close to with the inner wall of arc wall 2 to guarantee that the good gas tightness of blast pipe 1 prevents that tail gas from leaking, will get into through-hole 41 when the dust is adsorbed in, can make drum 4 can the natural occurrence rotate unhindered, and can take the dust out of blast pipe 1 outward.

Two electromagnets 7 are fixedly connected to the side wall of the exhaust pipe 1, the electromagnets 7 are opposite in heteropole, the two electromagnets 7 are symmetrically distributed along the horizontal axis of the exhaust pipe 1, a mechanism groove 8 is formed in the inner wall of the exhaust pipe 1, and a power supply device for supplying power to the electromagnets 7 is installed in the mechanism groove 8.

Power supply unit is including rotating impeller 9 of connecting in mechanism groove 8, and one of them blade of impeller 9 adopts the iron material to make, has seted up bar groove 10 on blast pipe 1's the inner wall, and bar groove 10 sliding connection has the slider 11 of magnetism system, and slider 11 passes through spring 12 elastic connection on the inner wall of bar groove 10, and the bar groove 10 is embedded to be equipped with helical coil 13, and the coupling of helical coil 13 is in the power supply circuit of electro-magnet 7.

In this embodiment, when the exhaust gas flows in the exhaust pipe 1, the impeller 9 is pushed to rotate, and when the impeller 9 rotates, the iron blades on the impeller 9 continuously approach and leave the magnetic slider 11. As shown in fig. 1, when the iron blade is close to the sliding block 11, the sliding block 11 can be attracted to move leftwards, and when the iron blade is far from the sliding block 11, the elastic force of the spring 12 is larger than the magnetic force to push the sliding block 11 to move rightwards, so that the sliding block 11 can move back and forth in the strip-shaped groove 10 during the rotation of the impeller 9.

When the slider 11 moves back and forth, the slider will continuously move in and out of the spiral coil 13, so that the magnetic flux in the spiral coil 13 is continuously changed. So can intermittent type nature produce induced current and the periodic power supply to two electro-magnets 7, will form the alternating magnetic field of the constantly changing of magnetic field intensity between two electro-magnets 7, because the half cycle of alternating current is longer, and the magnetic moment that silicon steel sheet 5 received is longer from the peak value to zero time, makes the restoring force of spring shaft 6 can make silicon steel sheet 5 gyration great angle. So can be in the exhaust emission in-process, under the magnetic force of alternating magnetic field and the elastic force of spring shaft 6 for silicon steel sheet 5 is swinging back and forth in glass section of thick bamboo 3, and the silk layer 51 of silicon steel sheet 5 one side will constantly rub with glass section of thick bamboo 3 inner wall, thereby produces static on glass section of thick bamboo 3 surface.

The smoke dust in the tail gas is attracted by static electricity and passes through the through hole 41 to be adsorbed on the outer wall of the glass cylinder 3, and the through hole 41 can effectively prevent the tail gas flowing horizontally from blowing off the adsorbed smoke dust. When the amount of the adsorbed soot is increased, the soot is gradually accumulated in the through hole 41, as shown in fig. 2, the part of the cylinder 4 in the exhaust pipe 1 is heavier, the cylinder 4 rotates under the action of gravity, the dust in the through hole 41 can be pushed out of the exhaust pipe 1, and the part of the glass cylinder 3 outside the exhaust pipe 1 does not contain static electricity, so that the dust is pushed out of the exhaust pipe 1 and then loses electrostatic force to be adsorbed, and then falls under the action of self gravity. Therefore, the smoke dust treatment work in the boiler tail gas can be completed, special tail gas dust removal equipment does not need to be erected, smoke dust accumulation cannot be generated in the exhaust pipe, and the tail gas emission efficiency of the exhaust pipe and the boiler combustion efficiency are improved.

Example two:

referring to fig. 4-6, different from the first embodiment, a rubber gas hood 14 is embedded in the glass cylinder 3, a plurality of unidirectional gas outlets 15 are formed in the inner bottom of the glass cylinder 3, the unidirectional gas outlets 15 correspond to the through holes 41 in one-to-one correspondence, and a unidirectional gas inlet pipe 16 communicated with the inside of the glass cylinder 3 is fixedly connected to the side wall of the glass cylinder.

It should be noted that the one-way air outlet 15 only allows air to exit from the glass cylinder 3 from the inside of the rubber air cap 14, and the one-way air inlet 16 only allows air to enter the inside of the rubber air cap 14 from the outside of the glass cylinder 3. During manufacturing, only the one-way valve is needed to be arranged in the air outlet hole or the air inlet pipe. Further, as shown in FIG. 6, the one-way exhaust holes 15 are provided only in a portion of the side wall of the glass cylinder 3 outside the exhaust pipe 1.

In this embodiment, the silicon steel sheet 5 will continuously extrude the rubber air hood 14 during the back and forth swinging process. When silicon steel sheet 5 extrudees rubber gas hood 14, can force the air in the rubber gas hood 14 to discharge from one-way venthole 15, in each through-hole 41 can be discharged to exhaust air, both can accelerate the speed that drops of dust, can make the dust more thorough that drops again simultaneously to improve the dust collection efficiency and the dust removal effect of this device. When the silicon steel sheet 5 leaves the rubber air hood 14, the rubber air hood 14 is recovered under the elasticity of itself, and air is sucked into the rubber air hood 14 through the one-way air inlet pipe 16 for supplementation.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
