Description

Technical Field

[0001] The invention relates to the technical field of gas separation and filtration, and in particular to an asphalt fume treatment and purification device. Background Art

[0002] The gas produced by the heating of asphalt and the combustion of asphalt-containing substances is asphalt fume. Asphalt fume may contain a variety of diffuse particles such as suspended fine particulate matter, solid hydrocarbon particles, gaseous hydrocarbon derivatives and carcinogens. If the asphalt fume is directly discharged into the atmosphere, it will pollute the surrounding environment and endanger human health. Therefore, the diffuse particles in the asphalt fume need to be separated and filtered to an acceptable level before the purified gas can be discharged.

[0003] When purifying asphalt smoke, the physical property of pollutants being able to dissolve in the absorption liquid can be utilized, and the water absorption method can be used to absorb and remove pollutants. However, the water absorption method consumes more water resources. Compared with the cold water flow method, the high-temperature spray method not only accelerates the movement of water molecules through high temperature, thereby more effectively capturing and absorbing the diffused particles in the asphalt smoke, so that most of the diffused particles combine with the high-temperature water mist to form larger water droplets and then settle, thereby purifying the flue gas, but also the water mist will reduce water loss and save energy. In addition, considering that the temperature of the asphalt flue gas itself is relatively high, temperature loss will lead to a large amount of heat energy waste. In view of this, an asphalt flue gas treatment and purification device is developed to address the above problems, which utilizes the heat of the flue gas to evaporate water vapor to capture diffused particles, which is of great significance for energy conservation and environmental protection in flue gas purification.

[0006] In one embodiment, the water tank is configured in a U-shape.

[0007] In one of the embodiments, the guide plate is configured as a copper plate with thermal conductivity.

[0008] In one embodiment, the steam port of the air guide pipe is inclined from the inner upper part to the outer lower part.

The floating plate is slidably connected to a slide plate, and the slide plate is slidably connected to the heating box. The heating box is fixedly connected to a second magnet, and both the first magnet and the second magnet cooperate with the slide plate through magnetic attraction.

[0010] In one embodiment, it also includes a first fixed tube for containing an expansion agent, the first fixed tube is fixedly connected to the water tank, the first fixed tube is fixedly connected to a limit plate, a piston is slidably connected between the first fixed tube and the limit plate, a first spring is fixedly connected between the piston and the first fixed tube, a rotary valve is rotatably connected to the water tank, and a connecting rod is rotatably connected between the piston and the rotary valve.

[0015] The beneficial effects are: 1. The present invention utilizes the heat of the asphalt smoke itself to heat water to form hot water vapor, thereby more effectively capturing and absorbing the dispersed particles in the asphalt smoke, so that most of the dispersed particles combine with the high-temperature water mist to form larger water droplets and then settle, thereby purifying the flue gas.

[0016] 2. The present invention guides the smoke to the third impeller through the fan, and at the same time the fan drives the third impeller to rotate, so that the purified smoke is discharged quickly, avoiding the smoke from being concentrated in the frame.

[0017] 3. The third impeller drives the rotating shaft to rotate, thereby driving the first impeller and the second impeller to rotate synchronously. The first impeller disperses the water vapor at the steam outlet so that the water vapor is evenly discharged from the steam outlet.

[0018] 4. Under the guidance of the guide blocks, water droplets flow downward through the gaps between adjacent guide blocks to the gaps between adjacent steam ports, and then flow downward along the wall of the air guide pipe, preventing water droplets from flowing to the steam port, causing the steam port to be blocked, thereby affecting the capture and purification of dispersed particles.

[0019] 5. The present invention uses the function of the floating plate to stop water intake when the water in the heating box is almost full and start water intake when the water is almost dry. In this way, water can be replenished from the water tank when the water level is insufficient without affecting the full water storage function of the water tank.

[0020] 6. On the basis of distributing water vapor through the steam port, the liquid wax expands due to heat, causing the rotary valve to rotate and open, and the water vapor in the water tank can also enter the frame, which can assist in heating and increase the steam volume, thereby improving the capture efficiency of diffuse particles.

[0021] 7. The present invention blocks water vapor through the rotating plate to prevent the residual water vapor from forming water droplets and dripping onto the fan when the fan is turned off, causing water intrusion and damage to the fan. Moreover, when blowing, the wind can be better directed to the third impeller by rotating the rotating plate at a certain angle, thereby increasing the wind force driving the third impeller to rotate.

[0022] 8. The present invention increases the contact surface of heat conduction, so that the water temperature rises rapidly, thereby accelerating the purification of smoke.

[0023] 9. The present invention prevents a large amount of rainwater from entering through the support frame. Water droplets on the top of the support frame will enter the second fixed pipe step by step from top to bottom through the inclined plates and be discharged downward to the ground, preventing a large amount of rainwater from entering the frame without affecting the discharge of smoke.

DETAILED DESCRIPTION

[0038] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0039] Embodiment 1: A asphalt fume treatment and purification device, combined with the attached Figure 1 To Attachment Figure 4 , including a frame 101, a water tank 102 for storing water is connected to the lower left side of the frame 101, the water tank 102 is set in a U-shape, a solenoid valve 103 is installed on the upper left side of the water tank 102, four axially distributed guide plates 104 are fixedly connected to one side of the frame 101 close to the water tank 102, the guide plates 104 are set as copper plates with thermal conductivity, a liquid level sensor 105 is fixedly connected to the upper front side of the water tank 102, the liquid level sensor 105 is electrically connected to the solenoid valve 103 through a control module, the inner lower part of the frame 101 is connected to a heating box 1051 for heating water, the heating box 1051 is connected to the water tank 102, the heating box 1051 A heating plate 106 is fixedly connected to the inner bottom, a fan 107 is fixedly connected to the upper left side of the frame 101, and the fan 107 faces the upper right. An air duct 108 is fixedly connected to the frame 101, and steam ports distributed in a longitudinal circumferential direction are opened on the upper portion of the air duct 108, and the steam ports of the air duct 108 are inclined from the inner upper portion to the outer lower portion, and a circumferential array of guide blocks 109 are fixedly connected to the air duct 108, and the gaps between adjacent guide blocks 109 correspond one to one to the gaps between adjacent steam ports. A rotating shaft is rotatably connected in the air duct 108, and a first impeller 110, a second impeller 111 and a third impeller 112 are fixedly connected to the middle, lower and upper portions of the rotating shaft of the air duct 108, respectively.

[0040] First, a proper amount of water is added into the heating box 1051 through the water tank 102, and the asphalt fume is introduced into the frame 101 through the guide plate 104. The heat of the asphalt fume itself causes the water in the heating box 1051 to evaporate, and the water vapor flows from bottom to top through the air guide pipe 108, and then overflows downward through the steam port. In summary, the present invention utilizes the heat of the asphalt fume itself to heat water to form hot water vapor, thereby more effectively capturing and absorbing the dispersed particles in the asphalt fume, so that most of the dispersed particles combine with the high-temperature water mist to form larger water droplets and then settle, thereby purifying the flue gas. In addition, the high-temperature water mist purification method can not only reduce the loss of heat energy, but also reduce the loss of water resources, making the purification of asphalt fume more efficient, energy-saving and environmentally friendly.

[0041] In the above purification process, if the asphalt flue gas has insufficient heat, resulting in insufficient steam, auxiliary heating can be performed through the heating plate 106; if the liquid level sensor 105 detects that the water in the water tank 102 is insufficient, the control module controls the solenoid valve 103 to open for water replenishment; the guide plate 104 is set as a copper plate, which can quickly transfer the heat in the flue gas to the water in the water tank 102, and the flue gas purified by high-temperature spray continues to float upward, and the flue gas is guided to the third impeller 112 by the fan 107. At the same time, the fan 107 blows the third impeller 112 to rotate, so that the purified flue gas is quickly discharged to avoid the flue gas from being concentrated in the frame 101; the third impeller 112 drives the rotating shaft The first impeller 110 and the second impeller 111 rotate synchronously, and the first impeller 110 breaks up the water vapor at the steam outlet so that the water vapor is evenly discharged from the steam outlet; the second impeller 111 quickly guides the generated water vapor into the air duct 108; the flue gas is suddenly cooled after passing through the high-temperature water mist, and water droplets are formed and scattered on the air duct 108 of the guide block 109. Under the guidance of the guide block 109, the water droplets flow downward through the gap between adjacent guide blocks 109 to the gap between adjacent steam outlets, and then flow downward along the wall of the air duct 108, preventing the water droplets from flowing to the steam outlet, causing the steam outlet to be blocked, thereby affecting the capture and purification of dispersed particles.

[0042] Embodiment 2: Based on embodiment 1, Figure 5 To Attachment Figure 6 , also includes a floating plate 201, the floating plate 201 is slidably connected to the heating box 1051 along the up and down directions, a first magnet 202 is fixedly connected to the upper left side of the heating box 1051, the floating plate 201 is slidably connected to the slide plate 203 along the up and down directions, the slide plate 203 is slidably connected to the heating box 1051, a second magnet 204 is fixedly connected to the left side of the inner bottom of the heating box 1051, and the first magnet 202 and the second magnet 204 are both cooperated with the slide plate 203 through magnetic attraction.

[0043] In order to be able to stop water intake when the liquid level in the heating box 1051 reaches a certain level and start water intake when the liquid level drops to a certain level, the specific operation is as follows: the float plate 201 rises and falls with the hot water level in the heating box 1051. When the liquid level rises, the float plate 201 first rises to contact the top of the slide plate 203, and then drives the slide plate 203 to rise together. The slide plate 203 is separated from the second magnet 204. When the slide plate 203 rises to be attracted by the first magnet 202, the connection between the heating box 1051 and the water tank 102 is blocked, and water intake into the heating box 1051 is automatically stopped. At this time, the water tank 102 can be continuously filled with water, and the water in the water tank 102 will not enter the heating box 1051 and then overflow into the frame 101.

[0044] When the liquid level drops, the float 201 first drops down to contact the bottom of the slide plate 203, and then drives the slide plate 203 to drop together, and the slide plate 203 separates from the first magnet 202. When the slide plate 203 drops down to be attracted by the second magnet 204, the connection between the heating box 1051 and the water tank 102 is opened, and water starts to flow into the heating box 1051 automatically.

[0045] In summary, the present invention uses the function of the floating plate 201 to stop water intake when the water in the heating box 1051 is almost full and start water intake when the water is almost dry. In this way, water can be replenished from the water tank 102 when the water level is insufficient without affecting the full water storage function of the water tank 102.

[0046] Combined with Figure 7 To Attachment Figure 8 , also includes a first fixed tube 301 for containing an expansion agent, the expansion agent in the first fixed tube 301 is set to liquid wax, the first fixed tube 301 is fixed to the front upper part of the water tank 102, a limit plate 3001 is fixed in the first fixed tube 301, a piston 302 is slidably connected between the first fixed tube 301 and the limit plate 3001 along the up and down directions, a first spring 303 is fixed between the piston 302 and the first fixed tube 301, a rotary valve 304 is rotatably connected to the upper part of the water tank 102, and a connecting rod 305 is rotatably connected between the piston 302 and the rotary valve 304.

[0047] On the basis of distributing water vapor through the steam port, water vapor is also supplemented by the following operations: heat is conducted to the liquid wax in the first fixed tube 301, the liquid wax expands due to the heat, thereby pushing the piston 302 to slide upward, the first spring 303 is stretched, the piston 302 pushes the rotary valve 304 to rotate and open through the connecting rod 305, and the water vapor in the water tank 102 enters the frame 101 through the rotary valve 304, which can assist heating and increase the steam volume, thereby improving the capture efficiency of dispersed particles. When ventilation stops, the liquid wax shrinks due to the cold, the first spring 303 resets and drives the piston 302 to slide downward, and the piston 302 pulls the rotary valve 304 to reverse and close through the connecting rod 305.

[0048] Embodiment 3: Based on Embodiment 2, Fig. 9 To Attachment Fig.10 , and also includes four longitudinally distributed rotating plates 401, which are all rotatably connected to one side of the frame 101 close to the fan 107, and connecting rods 402 are rotatably connected between the longitudinally distributed rotating plates 401, and a second spring 403 is fixedly connected between the upper rotating plate 401 and the frame 101, and a limiting frame 404 for limiting the connecting rod 402 is fixedly connected to the inner rear wall of the frame 101 to limit the opening angle of the rotating plate 401.

[0049] In order to prevent the residual water vapor from forming water droplets and dripping onto the fan 107 when the fan 107 is turned off, a rotating plate 401 is used to block it. When the fan 107 is blowing, the wind force causes the rotating plate 401 to swing downward at a certain angle. The rotating plate 401 drives the connecting rod 402 to rotate until it contacts the limit frame 404, thereby preventing the rotating plate 401 from rotating too much. In this way, the wind can be better guided to the upper right to the third impeller 112.

[0050] In summary, the present invention blocks water vapor through the rotating plate 401 to prevent the residual water vapor from forming water droplets and dripping onto the fan 107 when the fan 107 is turned off, causing the fan 107 to be damaged by water. Moreover, when blowing, the wind can be better directed to the third impeller 112 by rotating the rotating plate 401 at a certain angle, thereby increasing the wind force driving the third impeller 112 to rotate.

[0051] Combined with Fig.11 , and also includes a heat conducting plate 501 symmetrically distributed front and back, the heat conducting plates 501 symmetrically distributed front and back are fixed between the axially distributed flow guide plates 104, a heat conducting rod 502 is fixed to the bottom of the heat conducting plate 501, and the heat conducting plate 501 and the heat conducting rod 502 are both located in the water tank 102.

[0052] The heat of the guide plate 104 can also be guided to the water in the water tank 102 through the heat conduction plate 501 and the heat conduction rod 502 in sequence, and the water temperature is quickly increased by increasing the contact surface of heat conduction, thereby accelerating the purification of flue gas.

[0053] Combined with Fig.12 To Attachment Fig.13 , and also includes a support frame 601, which is fixed to the top of the frame 101. The four sides of the upper part of the support frame 601 are fixed with stacked inclined sheets 602. The gaps between the inclined sheets 602 are used for the circulation of liquid. The support frame 601 is circulated with a second fixed pipe 603.

[0054] To prevent a large amount of rainwater from entering the rack 101, the support frame 601 is used to prevent a large amount of rainwater from entering without affecting the discharge of smoke. The water droplets on the top of the support frame 601 will enter the second fixed pipe 603 step by step from top to bottom through the inclined sheet 602 and be discharged downward to the ground.
