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. 1-2, an inductance type automobile exhaust pretreatment device comprises a receiving pipe 1 and is characterized in that a hollow partition plate 2 is embedded in the receiving pipe 1, a rubber plate 3 is connected in the hollow partition plate 2 in a rotating mode, conductive rods 4 are fixedly connected to two opposite side walls of the rubber plate 3, and a plurality of through holes 21 are formed in the side walls of the hollow partition plate 2. Square groove 6 has been seted up to the lateral wall of receiver tube 1, and square groove 6 is embedded to be equipped with shell fragment 7, and shell fragment 7 adopts piezoceramics material to make, and gas pocket 61 has been seted up at the interior top in square groove 6.
The lateral wall of cavity baffle 2 rotates and is connected with axial compressor impeller 5, and axial compressor impeller 5's pivot and 3 fixed connection of rubber slab, and the lateral wall fixed connection of admission pipe 1 and the inside dust outlet pipe 8 that communicate of cavity baffle 2 install earth conductor in the dust outlet pipe 8.
It should be noted that the rubber plate 3 is arranged to insulate and separate the two conductive rods 4, so that the conductive rods 4 above the rubber plate 3 are suspended to generate induced electrification.
Further, the through holes 21 are distributed only above the rubber sheet 3. The axial flow impeller 5 drives the rubber plate 3 and the conducting rods 4 to rotate, so that when a certain conducting rod 4 adsorbs part of solid particles, the conducting rod 4 can be rapidly rotated to the position below the rubber plate 3, and on one hand, the solid particles adsorbed on the conducting rod 4 can be effectively prevented from being blown off by tail gas; on the other hand, can make two conducting rods 4 alternately electrified and adsorb solid particulate matters, improve the adsorption efficiency of this device greatly.
Due to the exhaust characteristics of the cylinder of the automobile engine, the automobile exhaust is discharged in a pulse mode. When the device is used, the device is additionally arranged in front of the automobile exhaust purifier, and automobile exhaust firstly passes through the receiving pipe 1 and then is discharged into the exhaust purifier.
In the process, when the tail gas flows in the receiving pipe 1, the tail gas can flow through the elastic sheet 7, the gas below the elastic sheet 7 has high flow rate and low pressure intensity, the air above the elastic sheet 7 has low flow rate and high pressure intensity, and the upper side and the lower side of the elastic sheet 7 generate air pressure difference, so that the elastic sheet 7 can be forced to bulge downwards; and when the tail gas is discharged at intervals, the difference between the flow velocity of the gas above and below the elastic sheet 7 is almost zero, the pressure difference between the gas above and below the elastic sheet 7 is extremely small, and the elastic sheet 7 is recovered upwards under the action of the elasticity of the elastic sheet. And because the interval of tail gas emission is extremely short, high-frequency vibration of the elastic sheet 7 can be caused, static charges can be gathered at two ends of the elastic sheet 7 under the action of the piezoelectric effect of the elastic sheet 7 made of piezoelectric ceramics, and the conductive rod 4 close to the end part of the elastic sheet 7 is induced to be electrified, so that the charges of the conductive rod 4 are redistributed and static electricity is also generated.
When tail gas flows, the tail gas enters the hollow partition board 2 through the through hole 21 and is discharged, the tail gas is contacted with the conducting rod 4, and solid particles in the tail gas are adsorbed on the conducting rod 4 by electrostatic attraction on the conducting rod 4. Meanwhile, the tail gas can also blow the axial flow impeller 5 to rotate, and drive the rubber plate 3 and the conducting rod 4 to rotate together, the conducting rod 4 is sequentially contacted with a grounding wire in the dust outlet pipe 8, the conducting rod 4 loses static electricity after being contacted with the grounding wire, and solid particles on the conducting rod 4 are discharged from the dust outlet pipe 8 under the action of self gravity after losing the electrostatic force for adsorption. So can make this device in the exhaust emission process, constantly adsorb the solid particle thing in the tail gas and get rid of, can carry out the preliminary treatment to tail gas, improve the purification rate of tail gas.
Example two:
referring to fig. 3, different from the first embodiment, one of the blades of the axial flow impeller 5 is made of a magnetic material, a strip-shaped groove 9 is formed on the inner wall of the receiving pipe 1, and an exhaust hole 91 is formed on the inner wall of the strip-shaped groove 9. The provision of the vent hole 91 facilitates the slider 10 to move back and forth unhindered.
It should be noted that the one-way liquid inlet pipe 12 only allows the cooling liquid to flow from the strip-shaped groove 9 to the rubber cylinder 14, and the one-way liquid outlet pipe 13 only allows the cooling liquid to flow from the rubber cylinder 14 to the strip-shaped groove 9. During specific manufacturing, only the one-way valve is needed to be arranged in the liquid inlet pipe or the liquid outlet pipe.
As shown in fig. 3, when the axial-flow impeller 5 rotates, the magnetic blades thereon will be continuously close to and far from the iron sliders 10 below. The slider 10 is attracted to move to the right whenever the magnetic blade is close to the slider 10, and the spring 11 pulls the slider 10 to move to the left when the magnetic blade is far from the slider 10, so that the slider 10 can move back and forth in the strip-shaped groove 9 when the axial flow impeller 5 rotates.
When the slide block 10 moves rightwards, the cooling liquid in the rubber tube 14 can be pumped into the strip-shaped groove 9 through the one-way liquid inlet pipe 12, the rubber tube 14 is deflated, and when the slide block 10 moves leftwards, the cooling liquid in the strip-shaped groove 9 can be pushed into the rubber tube 14 through the one-way liquid outlet pipe 13, and the rubber tube 14 is inflated and recovered. So can be at the round trip movement in-process of slider 10, force the one-way circulation flow of coolant liquid in one-way feed liquor pipe 12, so can reduce the temperature of discharging tail gas fast, can avoid high temperature tail gas to cause the harm to subsequent clarifier, prolong the signal life-span of clarifier.
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.
