Description

Technical Field

[0001] The invention relates to the technical field of purification treatment equipment, in particular to asphalt fume purification treatment equipment for asphalt concrete. Background Art

[0002] Asphalt fume is generated during the production and use of asphalt concrete. The fume contains a variety of harmful substances, including hydrocarbon compounds, phenolic compounds, asphalt particles, sulfides, nitrogen oxides, volatile organic compounds, etc. Direct emissions will have a significant impact on the environment and human health. Therefore, it is necessary to treat the flue gas through purification equipment to reduce the impact on the environment. The flue gas treatment methods include combustion, electrostatic capture, adsorption, induced draft dust removal and UV photo-oxidation catalytic activated carbon adsorption.

[0003] A Chinese patent with publication number CN105289164B discloses asphalt flue gas purification equipment, including a flue gas washing area, a first spraying device, a filler area and a second spraying device. When the asphalt flue gas comes into contact with a large amount of washing solvent, the temperature is greatly reduced, the flue gas diffusion rate is slowed down, and the tar and particulate matter in the asphalt flue gas can be effectively retained, and the purification effect of the asphalt flue gas is obvious.

[0004] The Chinese patent with publication number CN114917612B discloses an asphalt waterproofing membrane smoke treatment system, including an insulated batching tank, an environmental protection pipeline, a pressure cover plate and an asphalt smoke condensation tank. The asphalt smoke is passively discharged through the pressure cover plate connected to the opening of the environmental protection pipeline in the insulated batching tank, which reduces the asphalt smoke emission by 90%, greatly reduces pollutant emissions, and protects the environment.

[0037] In this embodiment, the heating mechanism 5 is equipped to guide the superheated water vapor generated in the combustion pot 11 through the guide pipe 55, so that the superheated water vapor flows on the surface of the intake pipe 51, and the smoke inside the intake pipe 51 is preheated. At the same time, the superheated water vapor can be controlled to flow into the inner side of the honeycomb box 58 through the control valve 1 510 or the control valve 2 511, so that the honeycomb box 58 heats the chemical reagent inside the chemical chamber 1 24 or the chemical chamber 2 25, and promotes chemical purification. The intake pipe 51 is installed through one side of the combustion pot 11 and communicates with the inner side of the combustion pot 11.

A group of control valves 2 511 are fixedly installed on the outside of the side tube 57 and the return pipe 59 connected to the chemical chamber 2 25, and each group has two control valves 2 511.

[0038] Specifically, the air inlet pipe 51 can provide a channel for the asphalt smoke to enter the combustion tank 11, the air inlet pipe 51 can provide a stable support for the square plate 52, the square plate 52 can provide a through space for the ventilation hole 53, the square plate 52 can provide a stable support for the heating tube 54, the heating tube 54 can provide a flow channel for water vapor, the square plate 52 divides the heating tube 54 into two parts, the front and back parts, so that the water vapor flows from the front of the square plate 52, passes through the ventilation hole 53, and then flows in the opposite direction from the back of the square plate 52, the outlet pipe 55 can export the high-temperature water vapor in the spiral groove 16 to the heating tube 54, and at the same time can balance the pressure in the spiral groove 16, so that the spiral groove 1 6 is the same as the water level in the water storage chamber 22.

[0039] In this embodiment, a cooling assembly 3 is provided on the inner side of the water tank 21, and the cooling assembly 3 is equipped to cool the flue gas through a condenser 35 to prevent the high temperature of the flue gas from affecting the chemical purification; the cooling assembly 3 includes a heat insulation plate 31, and the heat insulation plate 31 is fixedly installed on the top of the inner protrusion of the water tank 21, and a perforated plate 32 is fixedly installed on the top of the inner protrusion of the water tank 21, and the perforated plate 32 is located on one side of the heat insulation plate 31, and a water flow hole 33 is opened at the bottom of the perforated plate 32, and a guide block 34 is fixedly installed on the top of the protrusion of the water tank 21, and the guide block 34 is located between the heat insulation plate 31 and the perforated plate 32, and a condenser 35 is fixedly installed on the top of the water tank 21, and condensing pipes 36 are installed through both sides of the condenser 35, and the condensing pipes 36 penetrate the top of the water tank 21, and a hollow block 37 is fixedly installed on one end of the condensing pipe 36, and the hollow block 37 is located on the top of the guide block 34.

[0040] Specifically, the condenser 35 and the condenser tube 36 can provide cold air for the hollow block 37, so that the hollow block 37 cools the space at the protruding position of the water tank 21. Cooperating with the heat insulation plate 31, it can prevent the temperature in the water storage chamber 22 from affecting the temperature of the chemical chamber 24. At the same time, it can cool the high-temperature water vapor into small water droplets.

[0041] In this embodiment, a cutting mechanism 4 is provided inside the water storage tank 21. The cutting mechanism 4 is configured to cut the smoke bubbles by rotating the cutting plate 45 so that the smoke is fully in contact with the chemical reagent. The cutting mechanism 4 includes two ventilation pipes 41. One ventilation pipe 41 is installed through the inside of the insulation board 31, and the other ventilation pipe 41 is installed through the inside of the partition 23. An exhaust box 42 is fixedly installed at one end of the ventilation pipe 41. A plurality of air outlets 43 are opened on the top of the exhaust box 42. The air outlets 43 are distributed in a circular array. An inner ring 44 is installed on the top of the exhaust box 42 through a bearing sleeve, a cutting plate 45 is fixedly installed on the outer side of the inner ring 44, a bevel gear ring 46 is fixedly installed on the outer side of the cutting plate 45, a protective box 47 is installed through the inside of the partition 23, a double-headed motor 48 is fixedly installed on the inner side of the protective box 47, and the two output ends of the double-headed motor 48 pass through the interior of the protective box 47 through bearings respectively, and bevel gears 49 are fixedly installed on the outer sides of the two output ends of the double-headed motor 48, and the two bevel gears 49 are respectively meshed with the two bevel gear rings 46.

[0042] Specifically, the ventilation pipe 41 can guide the flow of flue gas so that the flue gas can enter the chemical reagent. The ventilation pipe 41 can provide stable support for the exhaust box 42. The exhaust box 42 can provide rotational support for the inner ring 44 through the bearing. The inner ring 44 can provide stable support for the cutting plate 45. The cutting plate 45 can provide stable support for the bevel gear ring 46. When the flue gas is discharged from the air outlet 43, the flue gas is easy to form continuous bubbles. The bevel gear 49 is driven to rotate by the double-headed motor 48. The cutting plate 45 is driven to rotate by the meshing action of the bevel gear 49 and the bevel gear ring 46, so that the cutting plate 45 cuts the continuous bubbles into multiple small bubbles, increasing the contact area between the flue gas and the chemical reagent, so that the flue gas can fully contact the chemical reagent. The protective box 47 can provide placement space and protection for the double-headed motor 48. The bearing between the output end of the double-headed motor 48 and the protective box 47 is a sealed bearing to prevent the chemical reagent from contacting the double-headed motor 48 and affecting the working performance of the double-headed motor 48.

[0043] Working principle: The staff places the device firmly at the designated work location, first opens the water inlet 27, and injects appropriate amounts of water and chemical reagents into the inner side of the water storage chamber 22, the chemical chamber 1 24, and the chemical chamber 2 25, respectively. The amount of water and chemical reagents is determined by observing the position of the liquid in the water level tube 28. The water inside the water storage chamber 22 enters the inner side of the spiral groove 16 from the through hole 17, so that the water levels inside the water storage chamber 22 and the spiral groove 16 are consistent, and the conductive rod 14 and the double-headed motor 48 are energized. The conductive rod 14 transmits electricity to the heating plate 18 and the heating wire 19, so that the heating plate 18 and the heating wire 19 generate heat, and the temperature of the heating wire 19 is controlled within 800 to 1000 degrees Celsius. Then the staff mixes the asphalt fume from the outside with oxygen and passes it into the inner side of the air intake pipe 51;

[0044] The asphalt fume and oxygen in the air intake pipe 51 enter the inner side of the combustion tank 11 through the air intake pipe 51, so that the asphalt fume rotates and moves upward along the spiral direction of the auger. When the asphalt fume passes near the heating wire 19, the combustible substances in the asphalt fume will burn under the action of oxygen and high temperature. Since the fume needs to pass through the heating wire 19 multiple times, the combustible substances in the asphalt fume are fully burned.

[0045] The smoke after combustion reaches the top of the combustion tank 11, and enters the inner side of the water storage chamber 22 under the guidance of the transition pipe 29, so that the smoke contacts the water inside the water storage chamber 22. The water can adhere to the surface of the solid particles, so that the water filters the solid particles in the smoke; the smoke passes through the inner side of the orifice plate 32 and the hollow block 37 and enters the ventilation pipe 41 inside the chemical chamber 24. The hollow block 37 cools the smoke under the action of the condenser 35, so that the cooled smoke passes through the ventilation pipe 41 and enters the inner side of the exhaust box 42, and moves upward through the air outlet 43 and enters the chemical reagent inside the chemical chamber 24. The smoke generates bubbles at the air outlet 43. At this time, the double-headed motor 48 drives the bevel gear The wheel 49 rotates, so that the bevel gear 49 drives the cutting plate 45 to rotate by meshing with the bevel gear ring 46. The cutting plate 45 rotates at the top of the air outlet 43, cutting the bubbles generated at the air outlet 43, so that the flue gas generates a large number of fine bubbles in the chemical reagent of the chemical chamber 1 24, so that the flue gas can fully contact with the chemical reagent, and some harmful gases in the flue gas are neutralized and purified. In the same principle, the flue gas in the chemical chamber 1 24 enters the inner side of the chemical chamber 2 25 through the ventilation pipe 41 on the partition 23, so that the flue gas is fully in contact with the chemical flue gas in the chemical chamber 2 25, and the other part of the harmful gases in the flue gas are neutralized and purified again, and the purified flue gas is discharged from the outlet pipe 26;

[0046] When the heating plate 18 heats to a high temperature, the heating plate contacts the water inside the spiral groove 16, so that the heating plate 18 vaporizes the water into high-temperature steam. The steam moves upward along the inner side of the spiral groove 16 under the action of atmospheric pressure. When the steam moves to the top of the inner side of the spiral groove 16, the steam enters the inner side of the outlet pipe 55, and the steam passes through the outlet pipe 55 and enters the inner side of the heating pipe 54. The steam moves along the front side of the square plate 52 and the surface of the intake pipe 51 in a direction away from the combustion tank 11, and then the steam passes through the passage 54. The air hole 53 comes to the back of the square plate 52, and moves along the back of the square plate 52 and the surface of the air inlet pipe 51 toward the direction of the combustion pot 11, so that the high-temperature water vapor passes through the air inlet pipe 51 to preheat the flue gas that is about to enter the inner side of the combustion pot 11, and finally the water vapor passes through the inlet pipe 56 and enters the raised position inside the water storage tank 21, so that the water vapor contacts the hollow block 37 to cool and condense into small water droplets, and the small water droplets fall on the top of the guide block 34, and under the guidance of the guide block 34, pass through the water flow hole 33 and enter the inner side of the water storage chamber 22;

[0047] When the staff needs to heat the chemical reagents inside the chemical chamber 24, the staff opens the two control valves 510 at the same time, so that part of the high-temperature water vapor in the heating tube 54 enters the inner side of the honeycomb box 58 under the drainage action of the side tube 57. The honeycomb box 58 heats up to heat the chemical reagents and promotes the chemical reaction. Then, the water vapor inside the honeycomb box 58 enters the raised part inside the water tank 21 from the back side of the water tank 21 through the reflux pipe 59 to be condensed and recovered. Similarly, the chemical reagents in the chemical chamber 25 can be heated through the two control valves 511 to improve the purification effect of the chemical reagents.
