Description

Technical Field

[0001] The invention belongs to the technical field of waste gas treatment, and in particular relates to a waste gas pre-treatment filtering and oil removal device and a use method thereof. Background Art

[0002] Exhaust gas pretreatment is a collection of technical means aimed at removing harmful components in exhaust gas and creating favorable conditions for subsequent treatment processes.

[0003] Filtration is a commonly used method in waste gas pretreatment. When filtering and separating the oil in some waste gases, the traditional simple filtration operation is not very effective in removing the oil, and regular manual cleaning operations are required.

[0004] Chinese patent CN108579309A provides a system and method for pre-treatment of oil fume waste gas, the system comprising a spray unit and an oil removal unit arranged in sequence along the flow direction of the oil fume waste gas to be treated; the oil removal unit comprises a first metal filter oil removal module and a second metal filter oil removal module arranged in sequence along the flow direction of the waste gas to be treated, the first metal filter oil removal module comprises a first metal wire mesh; the second metal filter oil removal module comprises a second metal wire mesh; further comprising a power unit for driving the first metal wire mesh and the second metal wire mesh to rotate; and a regeneration unit. The system and method for pre-treatment of oil fume waste gas can efficiently and continuously treat oil fume waste gas, with low water consumption, small amount of waste water, low requirements on the composition of waste gas, large amount of treated gas, and can be regenerated online for continuous operation, without manual cleaning, and is particularly suitable for waste gas containing oil components of different concentrations, and is also suitable for waste gas containing dust.

[0005] The inventors have discovered that although this reciprocating filtering method using a metal wire mesh can achieve filtering separation and does not require manual cleaning, the filtering efficiency of this metal wire mesh is limited. If the metal wire mesh is simply circulated and rotated, the oil in the exhaust gas cannot be fully separated from the gas due to the low collision probability of the exhaust gas passing through the metal wire mesh, thereby reducing the overall filtering and oil removal efficiency. Therefore, it is necessary to set a first metal wire mesh, a second metal wire mesh, a third metal wire mesh or even more in sequence. Only by increasing the number of metal wire meshes can the collision probability of the exhaust gas be increased to improve the overall filtering and oil removal efficiency. Such a design will result in the equipment being too large and the cost being too high.

[0006] Therefore, the existing structure and defects are studied and improved, and an exhaust gas pre-treatment filtration and oil removal equipment and a method of use are provided, in order to achieve a more practical purpose. Summary of the invention

[0018] A method for using an exhaust gas pre-treatment filtering and oil removal device, using the exhaust gas pre-treatment filtering and oil removal device, comprising the following steps:

[0019] S1 guides the exhaust gas into the oil removal channel, and at the same time enables the spray pipe to spray the passing exhaust gas with spray liquid;

[0020] The exhaust gas after spraying by S2 passes through the filter holes of the conveyor belt and enters the conveyor belt. Then, the running trajectory of the exhaust gas is changed through the inclined spoiler, so that the exhaust gas is discharged from the filter holes at the other end of the conveyor belt after multiple collisions. The collision process of the exhaust gas enables the adsorption cotton to repeatedly adsorb and separate the oil in the exhaust gas.

[0021] Compared with the prior art, the present invention has the following technical effects:

[0022] The addition of the spoiler can further disrupt the airflow passing through the filter hole, thereby effectively increasing the number of collisions of the airflow when passing through the conveyor belt.

[0023] The spoiler is composed of multiple spoiler panels, which can be selectively connected and fixed by engaging the card rod with the card slot. When the spoiler is tilted to block the filter hole, the card rod is engaged with the card slot, and the multiple spoiler panels can form an inflexible plate body. At this time, the spoiler can be rotated to disrupt the airflow passing through the filter hole. Since the conveyor belt is annular, when the spoiler passes through some curved places, the card rod can be separated from the card slot to form a rotatably connected and bendable shape of multiple spoiler panels. In this way, the spoiler can pass through some curved positions better, thereby improving the overall passability.

[0024] Through such a reciprocating manner, using the reciprocating conveyor belt, the adsorption cotton can continuously adsorb and separate the oil in the exhaust gas, thereby improving the overall filtration and oil removal efficiency.

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0040] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , an exhaust gas pre-treatment filtering and oil removal device, comprising an oil removal channel 1, an air inlet of the oil removal channel 1 is provided with a spray pipe 11, and an annular and rotatable conveyor belt 2 is provided in the oil removal channel 1, a plurality of evenly distributed first adjustment grooves 24 are provided on the side wall of the conveyor belt 2, and a plurality of groups of through-type and evenly distributed filter holes 21 are provided between adjacent first adjustment grooves 24, an adjustment rod 241 that can move back and forth is provided in the first adjustment groove 24, and a plurality of rotatable and used for adjusting the filter holes 21 are provided on the adjustment rod 241 The shielding spoiler 23 comprises a plurality of spoiler panels 231, one end of the spoiler panel 231 is provided with a fixedly connected convex plate 233, and the other end of the spoiler panel 231 is provided with a groove 232 corresponding to the convex plate 233, the convex plate 233 is rotatably connected to the groove 232, a slot 238 is provided in the groove 232, a retractable clamping rod 237 engaged with the slot 238 is provided in the convex plate 233, and the surfaces of the conveyor belt 2 and the spoiler 23 are provided with absorbent cotton for oil absorption.

[0041] The addition of the spoiler 23 can utilize the spoiler 23 to disrupt the airflow passing through the filter hole 21 again, thereby effectively increasing the number of collisions of the airflow when passing through the conveyor belt 2. Through the collision of the airflow and the adsorption of the adsorption cotton, the oil in the exhaust gas can be effectively adsorbed, thereby effectively improving the overall filtration and oil removal efficiency.

[0042] The spoiler 23 is composed of a plurality of spoiler panels 231, which can be selectively connected and fixed by the engagement of the clamping rod 237 and the clamping groove 238. When the spoiler 23 is tilted to block the filter hole 21, the clamping rod 237 and the clamping groove 238 are engaged, and the plurality of spoiler panels 231 can be formed into an inflexible plate body. At this time, the spoiler 23 can be rotated to disrupt the airflow passing through the filter hole 21. Since the conveyor belt 2 is annular, when the spoiler 23 passes through some curved places, the clamping rod 237 and the clamping groove 238 can be separated, so that the spoiler 23 as a whole forms a rotatably connected and bendable shape with a plurality of spoiler panels 231, so that the spoiler 23 can better pass through some curved positions, thereby improving the overall passability.

[0043] See also Figure 4 and Figure 5 In this embodiment, a connecting shaft 242 is rotatably connected between the adjusting rod 241 and the spoiler 23, a first pressing and telescopic mechanism 243 is fixedly connected at one end of the first adjusting groove 24, the telescopic end of the first pressing and telescopic mechanism 243 is fixedly connected to the adjusting rod 241, and a first pressing rod 236 is provided at the pressing end of the first pressing and telescopic mechanism 243. A first groove is provided in the oil removal channel 1, and a first rod 245 which is retractable and used to press the first pressing rod 236 is provided in the first groove. A plurality of fixedly connected wedges 246 are provided on the conveyor belt 2, the wedges 246 are fixed on one side of each group of filtering holes 21, and the wedges 246 are used to drive the spoiler 23 to be inclined, a first spring 244 is fixedly connected in the first groove, the first spring 244 is fixedly connected to the first rod 245, and the end of the first rod 245 is hemispherical.

[0044] By pressing the first pressing and retracting mechanism 243 with the first rod 245, the back-and-forth movement of the adjusting rod 241 can be controlled. By only setting the first rod 245 at a corresponding position, the spoiler 23 can be automatically displaced after passing through the set position. The addition of the wedge 246 can realize the automatic rotation of the spoiler 23 by utilizing the inclination of the wedge 246 during the displacement of the spoiler 23, so that the spoiler 23 can automatically form an inclined shape.

[0045] In this embodiment, the adjusting rod 241 is provided with a plurality of limiting baffles which are fixedly connected and used to limit the rotation angle of the spoiler 23. The addition of the limiting baffles can effectively prevent the spoiler 23 from tilting downward when the spoiler 23 moves from the upward tilt to the other end, so that the spoiler 23 can still form an upward tilt. Such a design can effectively improve the collision efficiency of the airflow.

[0046] See also Figure 5 and Figure 6 In this embodiment, a second adjusting groove 230 is provided at the end of the convex plate 233, and the clamping rod 237 is slidably connected in the second adjusting groove 230. A fixedly connected second pressing and telescopic mechanism 235 is provided in the adjusting groove, and the telescopic end of the second pressing and telescopic mechanism 235 is fixedly connected to the clamping rod 237. A fixedly connected first telescopic rod 234 is provided at the other end of the second adjusting groove 230. The upper end of the first telescopic rod 234 movably passes through the side wall of the second adjusting groove 230. A second pressing rod is provided at the pressing end of the second pressing and telescopic mechanism 235. A fixedly connected second telescopic rod 239 is provided at the end of the second pressing rod. The end of the second telescopic rod 239 is fixedly connected to the bottom of the first telescopic rod 234, and the second telescopic rod 239 is communicated with the inside of the first telescopic rod 234.

[0047] The addition of the second pressing and telescopic mechanism 235, the second telescopic rod 239 and the first telescopic rod 234 can realize pressing of the second pressing and telescopic mechanism 235 by pressing the first telescopic rod 234, i.e., through the transmission of the second telescopic rod 239, thereby realizing automatic telescopic control of the locking rod 237.

[0048] See also Figure 2 , Figure 4 and Figure 7 In this embodiment, a plurality of adjustment plates 25 are provided in the conveyor belt 2, and the adjustment plates 25 are fixedly connected to the inner wall of the oil removal channel 1. A plurality of retractable second rods 253 are provided on the adjustment plate 25 and used for pressing the first retractable rod 234. A plurality of second grooves 252 are provided on the adjustment plate 25, and the second rods 253 are slidably connected in the second grooves 252. A second spring 251 is provided in the second groove 252 for driving the second rod 253 to pop out, and the end of the second rod 253 is hemispherical.

[0049] The addition of the adjustment plate 25 can utilize the elasticity of the second spring 251 to make the first telescopic rod 234 move to the second rod 253 when the spoiler 23 passes through the adjustment plate 25, so that the second rod 253 can press the first telescopic rod 234. At this time, the second pressing and telescopic mechanism 235 can be pressed, and the telescopic control of the locking rod 237 can be achieved.

[0050] See also Figure 1 , Figure 2 , Figure 3In this embodiment, an upper oil removal tank 12 is provided at the upper end of the oil removal channel 1, which is connected and fixedly connected, and a lower oil removal tank 13 is provided at the bottom of the oil removal channel 1, and a rotatably connected conveying shaft 22 is provided in both the upper oil removal tank 12 and the lower oil removal tank 13, and a fixedly connected oil removal plate 121 is provided in the middle of the upper oil removal tank 12, and a V-shaped oil removal groove for collecting waste oil is provided on the oil removal plate 121, and a rotatable oil removal roller 122 is provided in the middle of the oil removal groove, and the conveying shaft 22 and the oil removal roller 122 drive the conveyor belt 2 to be tensioned, and a driving motor for driving one of the conveying shafts 22 to rotate is provided on one side of the lower oil removal tank 13, and a separation liquid for separating oil from the conveyor belt 2 is provided in the lower oil removal tank 13.

[0051] The design of the upper de-oiling box 12 and the de-oiling tank can utilize the extrusion of the de-oiling roller 122 and the extrusion between the conveyor belt 2 and the side wall of the de-oiling tank to fully squeeze and separate the oil in the adsorption cotton on the conveyor belt 2 and the spoiler 23, and uniformly collect them in the de-oiling tank, thereby realizing the automatic separation of the oil on the adsorption cotton;

[0052] The separation liquid design in the lower de-oiling tank 13 can soak the absorbent cotton with the separation liquid, so that the oil on the absorbent cotton can be separated more thoroughly. In order to prevent the absorbent cotton from being unable to absorb the oil due to excessive separation liquid adsorbed on the absorbent cotton, the adjustment plate 25 can be set above the separation liquid level, and the distance between the adjustment plate 25 and the inner wall of the upper de-oiling tank 12 can be controlled so that the adjustment plate 25 can repeatedly squeeze and separate the separation liquid on the surface of the conveyor belt 2 and the spoiler 23, so that the absorbent cotton entering the de-oiling channel 1 can still have good adsorption force.

[0053] See also Figure 4 In this embodiment, the conveying shaft 22 is provided with a plurality of conveying annular grooves 221 for the spoiler 23 to pass through.

[0054] The addition of the conveying annular groove 221 can make use of the conveying annular groove 221 to enable the spoiler plate 231 to pass through the conveying shaft 22 better.

[0055] In the present embodiment, the first push-telescopic mechanism 243 and the second push-telescopic mechanism 235 both adopt the push-telescopic mechanism in the existing field of push-type ballpoint pens. Since this is the existing technology, this application will not provide too much description on this.

[0056] In this embodiment, there are four adjustment plates 25 and four first slots, and the adjustment plates 25 are located on the side walls of the upper de-oiling tank 12 and the lower de-oiling tank 13 respectively.

[0057] When using this application:

[0058] First, the air flow in the oil removal channel 1 is sprayed by the spray pipe 11 to improve the separation efficiency of the oil in the exhaust gas;

[0059] Then the exhaust gas encounters the conveyor belt 2, and enters the conveyor belt 2 through the filter hole 21 on the conveyor belt 2. Since there is an inclined spoiler 23 on the other side of the filter hole 21, the exhaust gas first collides with the spoiler 23, and then moves to the other side of the conveyor belt 2. There is also an inclined spoiler 23 on the inner wall of the filter hole 21 on the other side. Therefore, after the exhaust gas collides with the corresponding spoiler 23 again, it passes through the filter hole 21 and then enters the subsequent processing equipment. The combination of the filter hole 21 and the spoiler 23 can fully improve the contact probability between the oil in the exhaust gas and the adsorption cotton, thereby improving the adsorption and separation efficiency of the oil in the exhaust gas;

[0060] When the adsorbent cotton on the conveyor belt 2 and the spoiler 23 in the oil removal channel 1 has been adsorbed for a certain period of time, the driving motor can be driven to drive the conveyor belt 2 to rotate, so that the adsorbent cotton adsorbed with oil at the air inlet end moves upward, and when the adjustment groove on the corresponding spoiler 23 moves to the corresponding first groove, the first rod 245 in the first groove automatically extends due to the elasticity of the first spring 244, so that the first rod 245 presses the first pressing rod 236, thereby driving the adjustment rod 241 to move from one end to the other end through the first pressing and retracting mechanism 243, and at this time the spoiler 23 is separated from the corresponding wedge 246, so that the spoiler 23 automatically changes from an inclined state to a vertical state, and the spoiler 23 moves from one side of the filter hole 21 to the conveyor belt 2 between the adjacent filter holes 21;

[0061] As the conveyor belt 2 continues to move, the spoiler 23 moves to the adjusting plate 25, and the second rod 253 in the adjusting plate 25 can automatically press the first telescopic rod 234 on the spoiler dividing plate 231 under the action of the second spring 251, so that the second pressing and telescopic mechanism 235 drives the clamping rod 237 to separate from the clamping groove 238, so that the spoiler 23 is transformed from a plate body into a bendable shape. In this way, when the spoiler 23 continues to move to the conveying shaft 22 as the conveyor belt 2 continues to move, it can be directly passed through the conveying shaft 22 by bending and cooperating with the conveying ring groove 221, and can make the conveyor belt 2 and the spoiler 23 containing oil move into the degreasing groove as the conveyor belt 2 rotates, and the outer surface of the conveyor belt 2 is squeezed by the degreasing roller 122 and the conveyor belt 2 is squeezed by the degreasing roller 122, so that the conveyor belt 2 is squeezed against the inner wall of the degreasing groove, so that the oil on the cotton adsorbed on the inner and outer surfaces of the conveyor belt 2 can be fully squeezed and separated, and uniformly collected by the degreasing groove;

[0062] As the conveyor belt 2 continues to rotate, the spoiler plate 23 passes through the other conveying shaft 22. At this time, the spoiler plate 23 is located at the other side of the upper de-oiling box 12. When the spoiler plate 23 passes the adjusting plate 25 on the other side of the upper de-oiling box 12, the second rod 253 on the adjusting plate 25 can automatically press the first telescopic rod 234 on the spoiler dividing plate 231 again. At this time, the spoiler dividing plate 231 automatically changes from a bendable shape to a plate shape. When the spoiler dividing plate 231 is completely separated from the adjusting plate 25, the spoiler plate 23 moves to the corresponding first groove. The first rod 245 in the first groove can press the first pressing and telescopic mechanism 243 again, so that the adjusting rod 241 automatically moves from one end of the adjusting groove to the other end. Due to the presence of the wedge 246 and the limit baffle, the spoiler plate automatically becomes an upwardly inclined shape. At this time, the spoiler plate 23 moves to the other side of the conveyor belt 2 in the de-oiling channel 1.

[0063] Since the amount of oil adsorbed on the other side of the conveyor belt 2 is less than the amount of oil adsorbed on the air inlet end of the conveyor belt 2, as the conveyor belt 2 continues to rotate, the spoiler plate 23 moves downward into the lower de-oiling box 13. After entering the lower de-oiling box 13, the spoiler plate 23 will first move to the corresponding first rod 245, driving the adjusting rod 241 to move back, and then the spoiler plate 23 will move to the adjusting plate 25. The adjusting plate 25 will first squeeze the spoiler plate 23 tilted upward into a vertical shape, and the second rod 253 on the adjusting plate 25 can press the second pressing and telescopic mechanism 235 again to separate the clamping rod 237 from the clamping groove 238, so that the spoiler plate 23 is automatically transformed from a plate shape to a bendable shape. In this way, the spoiler plate 23 can better pass through the two conveying shafts 22 in the lower de-oiling box 13, and the adsorption cotton in the lower de-oiling box 13 can contact with the separation liquid, thereby fully separating the oil in the adsorption cotton.

[0064] As the conveyor belt 2 continues to move, the separated spoiler 23 will first contact the adjustment plate 25 on the other side of the lower de-oiling tank 13, so that the adjustment plate 25 can not only fully squeeze and separate the spoiler 23 and the separation liquid of the adsorbent cotton on the conveyor belt 2, but also the second rod 253 in the adjustment plate 25 can press the second pressing and telescopic mechanism 235 again, so that the clamping rod 237 and the clamping groove 238 are automatically engaged, and at this time, the spoiler 23 automatically changes from a bendable shape to a plate shape;

[0065] As the conveyor belt 2 continues to move, the spoiler 23 moves to the first rod 245, so that the first rod 245 drives the adjustment rod 241 to move toward one end of the wedge 246, so that the spoiler 23 automatically forms a downward tilt on the other side of the filter hole 21.

[0066] By using such a reciprocating manner, the conveyor belt 2 is used to reciprocate, so that the adsorption cotton can continuously adsorb and separate the oil in the exhaust gas.

[0067] A method for using an exhaust gas pre-treatment filtering and oil removal device, using the exhaust gas pre-treatment filtering and oil removal device, comprising the following steps:

[0068] S1 directs the exhaust gas into the oil removal channel 1, and at the same time causes the spray pipe 11 to spray the passing exhaust gas with spray liquid;

[0069] The waste gas after spraying S2 passes through the filter hole 21 of the conveyor belt 2 and enters the conveyor belt 2. Then, the running trajectory of the waste gas is changed by the inclined spoiler 23, so that the waste gas is discharged from the filter hole 21 at the other end of the conveyor belt 2 after multiple collisions. The collision process of the waste gas enables the adsorption cotton to repeatedly adsorb and separate the oil in the waste gas.
