Asphalt mixture smoke treatment device

Abstract

The present application provides an asphalt mixture smoke treatment device, including a dust suppression box, in which rows of nozzles are arranged, and a spraying mechanism for driving the nozzles to swing back and forth. The present application can drive the nozzles to swing back and forth while spraying water mist by setting a spraying mechanism. Compared with a static nozzle that directly sprays water mist from the top surface of a spray tower, this method can throw the water mist farther and then drop it downward, thereby making the overall moving path of the water mist longer, being able to wrap more smoke and dust, and effectively improving the overall dust reduction effect of the device; and the nozzle can adjust the amplitude and speed of the swing according to the size of the smoke and dust; when the smoke and dust are relatively small, the swing amplitude of the nozzle is small, the swing speed is slow, and the range of the water mist thrown out is relatively small; when the smoke and dust are relatively large, the swing amplitude of the nozzle is large, the swing speed is fast, and the range of the water mist thrown out is relatively large.

Description

Technical Field

[0001] The present invention relates to the field of flue gas treatment, and in particular to an asphalt mixture flue gas treatment device. Background Art

[0002] The volatiles in asphalt fume are released into the atmosphere and become one of the air pollutants. The components of asphalt fume are extremely complex and vary with the source of asphalt. Asphalt fume contains both solid and liquid particles condensed from the volatile components of asphalt, and organic matter in vapor state. Asphalt fume is generally mixed with a certain concentration of smoke and dust, and is brown or black, with a strong irritating effect. The prevention and control measures for asphalt fume pollution are to first conduct closed exhaust on the equipment that produces asphalt fume, and then discharge it after purification.

[0003] Traditional flue gas treatment devices often include a spray tower for water mist dust reduction, and the nozzles in the spray tower are often set at the top of the tower, spraying water directly downwards. The direct falling of water mist will cause the water mist to move shorter in the tower. The exhaust gas is not in sufficient contact with the water mist, making it difficult to wrap more smoke and dust.

[0004] For example: The "A Waste Gas Spray Treatment Device" disclosed in the Chinese invention patent (application number: CN202211713540.5) discloses in its specification that the existing waste gas spray treatment device does not have sufficient contact with the purification liquid during use, which easily leads to poor working effect of the waste gas spray; the above patent can prove the defects of the prior art.

[0005] Therefore, we made improvements to this and proposed an asphalt mixture smoke treatment device. Summary of the invention

DETAILED DESCRIPTION

[0036] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0037] As described in the background technology, traditional flue gas treatment devices often include a spray tower for water mist dust reduction, and the nozzles in the spray tower are often set at the top of the tower to spray water directly downwards. The direct falling of water mist will cause the water mist to move shorter in the tower. The exhaust gas is not in sufficient contact with the water mist, making it difficult to wrap more smoke dust.

[0038] In order to solve this technical problem, the present invention provides an asphalt mixture smoke treatment device, which is used for smoke treatment in the asphalt manufacturing process.

[0039] Specifically, please refer to Figure 1-3 , an asphalt mixture smoke treatment device, specifically includes a dust reduction box 1, in which rows of nozzles 2 are arranged, and a spraying mechanism 3 for driving the nozzles 2 to swing back and forth.

[0040] By setting up the spraying mechanism 3, the nozzle 2 can be driven to swing back and forth while spraying water mist. Compared with the static nozzle 2 that directly sprays water mist from the top surface of the spray tower, this method can throw the water mist farther and then drop it downward, thereby making the overall spraying range of the water mist larger, and thus being able to handle more smoke and dust, effectively improving the dust reduction effect on asphalt smoke.

[0041] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0042] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0043] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0044] Example 1, please refer to Figure 1-Figure 3 The spraying mechanism 3 includes a bearing seat 31 fixed on the inner wall of the dust suppression box 1, and two bending rods 32 are fixedly connected to the lower surface of the bearing seat 31. An active rod 33 is rotatably connected to the two bending rods 32, and a push rod 34 is rotatably connected to the free end of the active rod 33.

[0045] A circular shell 35 is axially limited and slidably connected to the bearing seat 31, and a horizontal shaft 36 is passed through the circular shell 35 and is rotatably connected to it. Rectangular frames 37 are sleeved at both ends of the horizontal shaft 36. The push rod 34 is slidably connected to the strip groove on the surface of the rectangular frame 37. The same cross bar 38 is fixedly connected between the two adjacent rectangular frames 37, and a row of nozzles 2 is installed on the cross bar 38.

[0046] The active rod 33 is driven to rotate by an external motor, and the active rod 33 can drive the push rod 34 located at one end thereof to rotate accordingly. The push rod 34 can push the rectangular frame 37 to swing back and forth. The two adjacent rectangular frames 37 can drive the cross bar 38 to swing back and forth accordingly, and the cross bar 38 can drive the nozzle 2 to swing back and forth accordingly.

[0047] Example 2 further optimizes the asphalt mixture smoke treatment device provided in Example 1. Specifically, Figure 1-Figure 4 As shown, the spraying mechanism 3 also includes a slide rod 39 fixed on the surface of the circular shell 35 and slidably connected to the bearing seat 31, and an electric push rod 310 is fixedly connected between the slide rod 39 and the inner wall of the dust reduction box 1.

[0048] When there is less smoke and dust, the circular housing 35 and the horizontal axis 36 are located farther from the center of rotation of the active rod 33, and the swing amplitude of the rectangular frame 37, the horizontal rod 38 and the nozzle 2 is smaller and slower;

[0049] When there is a lot of smoke and dust, the temperature in the dust reduction box 1 will gradually increase, and the electric push rod 310 can push the slide bar 39 to move in the direction of the arrow E, and the slide bar 39 can drive the circular shell 35 to move in the direction of the arrow E. The circular shell 35 can drive the horizontal axis 36 to move in the direction of the arrow E, so that the position of the horizontal axis 36 is closer to the center of rotation of the active rod 33. At this time, the swing amplitude of the rectangular frame 37, the horizontal bar 38 and the nozzle 2 is larger, and the swing speed is faster.

[0050] Example 3

[0051] The asphalt mixture smoke treatment device provided in Example 1 or 2 is further optimized. Specifically, Figure 5-Figure 6 As shown, a conveying mechanism 4 for conveying water is arranged in the dust suppression box 1 .

[0052] By providing the delivery mechanism 4, the external water source can be delivered without using an external water pump, and the delivery speed of the water source can change with the swing state of the nozzle 2;

[0053] When the smoke and dust in the dust suppression box 1 is relatively small, the swing amplitude of the nozzle 2 is small, the swing speed is slow, and the water delivery amount is relatively small, which can reduce the water consumption while ensuring the dust suppression efficiency;

[0054] When the smoke and dust in the dust suppression box 1 is relatively large, the swing amplitude of the nozzle 2 is larger, the swing speed is faster, and the water delivery volume is relatively more, thereby improving the dust suppression efficiency.

[0055] The conveying mechanism 4 includes a partition 41 integrally fixed in the circular shell 35, and a rectangular piston plate 42 located in the circular shell 35 is fixedly installed on the transverse axis 36. The partition 41 and the rectangular piston plate 42 divide the space in the circular shell 35 into two parts.

[0056] The conveying mechanism 4 also includes two water outlet pipes 43 fixed on the surface of the circular shell 35 and interconnected with the interior thereof, and the two water outlet pipes 43 are respectively located on the upper and lower sides of the partition 41, and a one-way water outlet valve 44 is installed on the two water outlet pipes 43. Two water inlet pipes 45 interconnected with the interior thereof are integrally fixed on the surface of the circular shell 35, and the two water inlet pipes 45 are respectively located on the upper and lower sides of the partition 41, and a one-way water inlet valve 46 is installed on the two water inlet pipes 45.

[0057] The horizontal axis 36, the rectangular frame 37 and the horizontal bar 38 are all hollow structures and are interconnected. Two connecting pipes 47 that are interconnected with the interior of the horizontal axis 36 are fixedly connected to the surface of the horizontal axis 36. The two connecting pipes 47 correspond to the two water outlet pipes 43 one by one, and a hose is fixedly installed between the connecting pipe 47 and the water outlet pipe 43. The two water inlet pipes 45 extend to the outside of the dust suppression box 1 and are connected to an external water source.

[0058] When the rectangular frame 37 swings back and forth, it can drive the horizontal axis 36 to rotate back and forth. The horizontal axis 36 can drive the rectangular piston plate 42 fixed on its surface and located in the circular shell 35 to swing back and forth. During the swinging process, the rectangular piston plate 42 can suck the external water source into the circular shell 35 through the water inlet pipe 45, and then transport the water in the circular shell 35 to the cross bar 38 through the water outlet pipe 43, the hose, the connecting pipe 47, the horizontal axis 36, and the rectangular frame 37 in sequence, and spray it out through the nozzle 2.

[0059] In use, the swing amplitude and speed of the rectangular piston plate 42 are the same as those of the nozzle 2. When the swing amplitude of the nozzle 2 is small and the swing speed is slow, the overall water consumption is relatively small while ensuring the dust reduction effect;

[0060] When the swing amplitude of the nozzle 2 is large and the swing speed is fast, the overall water consumption will increase relatively to cope with more smoke and dust;

[0061] Example 4

[0062] The asphalt mixture smoke treatment device provided in the above embodiments is further optimized, such as Figure 1 , Figure 7 , Figure 8 As shown, a filter screen 5 for filtering sewage after dust reduction and a replacement mechanism 6 for updating the filter screen 5 are arranged in the dust reduction box 1 .

[0063] In use, the filter 5 can filter the sewage after dust removal, so as to facilitate the subsequent secondary use of the sprayed water. If the filter 5 is blocked, its filtering effect will be reduced.

[0064] By setting up a replacement mechanism 6, the filter 5 can be replaced, and the replacement speed of the replacement mechanism 6 can change with the change of precipitation in the dust reduction box 1. When the precipitation is small, the update speed of the filter 5 is relatively slow, and when the precipitation is high, the update speed of the filter 5 becomes relatively fast.

[0065] The replacement mechanism 6 includes a gear 1 61 sleeved on the surface of the horizontal shaft 36, a tubular shaft 62 is rotatably connected to the surface of the circular shell 35, a gear 2 63 meshing with the gear 1 61 is sleeved on the outer wall of the tubular shaft 62, a ratchet 64 is fixed on the inner wall of the tubular shaft 62, a rotating shaft 65 is rotatably connected to the surface of the circular shell 35, a mounting seat 66 is sleeved on the rotating shaft 65, a vertical rod 67 is vertically fixed on the surface of the mounting seat 66, a ratchet 69 is telescopically inserted at the upper end of the vertical rod 67, and a spring 2 68 sleeved on the surface of the vertical rod 67 is fixedly connected between the ratchet 69 and the mounting seat 66.

[0066] When the horizontal shaft 36 swings back and forth, it can drive the gear 1 61 sleeved on its surface to rotate back and forth. The gear 1 61 can drive the gear 2 63 meshing with it to rotate. The gear 2 63 can drive the ratchet 64 to rotate back and forth through the tubular shaft 62. The ratchet 64 can drive the rotating shaft 65 to rotate intermittently in one direction through the ratchet teeth 69.

[0067] The replacement mechanism 6 also includes a winding shaft 610 and a storage shaft 611 which are rotatably connected to the dust suppression box 1 and distributed on the left and right. The storage shaft 611 is positioned higher than the winding shaft 610. The filter 5 is wound on the storage shaft 611, and the other side of the filter 5 is wound on the winding shaft 610. A rod body 1 613 is fixedly connected to the side wall of the circular shell 35, and one end of the rod body 1 613 is rotatably connected to a guide shaft 1 614. A rod body 2 615 and a rod body 3 616 are vertically fixed to the upper surface of the supporting seat 31. One end of the rod body 2 615 is rotatably connected to a guide shaft 2 617, and one end of the rod body 3 616 is rotatably connected to a guide shaft 3 618. A belt 612 is connected for transmission between the guide shaft 1 614, the guide shaft 2 617, the guide shaft 3 618, the rotating shaft 65 and the winding shaft 610.

[0068] When the rotating shaft 65 rotates intermittently, the belt 612 can drive the reel 610 to rotate intermittently, and the reel 610 can reel in the clogged filter 5, while the storage shaft 611 can release a new filter 5 for use.

[0069] An L-shaped plate located below the reel 610 is fixed in the dust reduction box 1 , and impurities filtered out by the filter 5 flow into the space formed between the L-shaped plate and the dust reduction box 1 .

[0070] In addition, a horizontal plate located above the storage shaft 611 is fixed in the dust reduction box 1 to cover the unused filter 5 .

[0071] When the circular shell 35 moves in the direction indicated by the arrow E, it can drive the rod body 613, the guide shaft 614, and the rotating shaft 65 to move accordingly, causing the length of the belt 612 between the guide shaft 1 614 and the guide shaft 3 618 to shorten, while the length of the belt 612 between the guide shaft 2 617 and the rotating shaft 65 to extend.

[0072] The use process of the asphalt mixture smoke treatment device provided by the present invention is as follows:

[0073] Working principle:

[0074] In use, asphalt fume enters the dust reduction box 1 through the air inlet at the top of the dust reduction box 1, and after the fume is processed, it is discharged through the air outlet below the dust reduction box 1. The air outlet is located below the filter 5. The air inlet and air outlet of the dust reduction box 1 are not shown in the figure.

[0075] The active rod 33 is driven to rotate by an external motor, and the active rod 33 can drive the push rod 34 at one end thereof to rotate accordingly, and the push rod 34 can push the rectangular frame 37 to swing back and forth, and the two adjacent rectangular frames 37 can drive the cross bar 38 to swing back and forth with the horizontal axis 36 as the axis, and the cross bar 38 can drive the nozzle 2 to swing back and forth accordingly;

[0076] When there is less smoke and dust, the circular housing 35 and the horizontal axis 36 are located farther from the center of rotation of the active rod 33, and the swing amplitude of the rectangular frame 37, the horizontal rod 38 and the nozzle 2 is smaller and slower;

[0077] When there is a lot of smoke and dust, the temperature in the dust suppression box 1 will gradually increase, and the electric push rod 310 can push the slide bar 39 to move in the direction indicated by the arrow E, and the slide bar 39 can drive the circular shell 35 to move in the direction indicated by the arrow E, and the circular shell 35 can drive the horizontal axis 36 to move in the direction indicated by the arrow E, so that the position of the horizontal axis 36 is closer to the center position of the active rod 33. At this time, the swing amplitude of the rectangular frame 37, the cross bar 38 and the nozzle 2 is larger, and the swing speed is faster;

[0078] When the rectangular frame 37 reciprocates, it can drive the horizontal axis 36 to reciprocate and rotate accordingly, and the horizontal axis 36 can drive the rectangular piston plate 42 fixed on its surface and located in the circular shell 35 to reciprocate and swing accordingly. During the swinging process, the rectangular piston plate 42 can suck the external water source into the circular shell 35 through the water inlet pipe 45, and then transport the water in the circular shell 35 to the cross bar 38 through the water outlet pipe 43, the hose, the connecting pipe 47, the horizontal axis 36, and the rectangular frame 37 in sequence, and spray it out through the nozzle 2;

[0079] In use, the swing amplitude and speed of the rectangular piston plate 42 are the same as those of the nozzle 2. When the swing amplitude of the nozzle 2 is small and the swing speed is slow, the overall water consumption is relatively small while ensuring the dust reduction effect;

[0080] When the swing amplitude of the nozzle 2 is large and the swing speed is fast, the overall water consumption will increase relatively to cope with more smoke and dust;

[0081] When the horizontal shaft 36 swings back and forth, it can drive the gear 1 61 sleeved on its surface to rotate back and forth, and the gear 1 61 can drive the gear 2 63 meshing with it to rotate, and the gear 2 63 can drive the ratchet 64 to rotate back and forth through the tubular shaft 62, and the ratchet 64 can drive the rotating shaft 65 to intermittently rotate in one direction through the ratchet teeth 69;

[0082] When the rotating shaft 65 rotates intermittently, the belt 612 can drive the reel 610 to rotate intermittently, and the reel 610 can reel in the clogged filter 5, while the storage shaft 611 can release a new filter 5 for use.
