Description

Technical Field

[0001] This utility model relates to the field of asphalt fume purification technology, specifically to an efficient asphalt fume recovery and purification device. Background Technology

[0002] Methods for recovering and purifying asphalt fumes mainly include electrostatic precipitation, combustion, adsorption, and plasma methods. Among these, adsorption purification faces challenges. Since the condensation point of asphalt vapor is approximately 200°C, if the temperature drops below the condensation point during adsorption, it easily adheres to the adsorption layer, forming liquid or solid asphalt, thus affecting subsequent purification efficiency and effectiveness. Furthermore, the presence of oil on the adsorption layer makes maintenance and replacement inconvenient. Utility Model Content

[0003] The technical problem this invention aims to solve is that asphalt vapor easily adheres to the adsorption layer, forming liquid or solid asphalt, which in turn affects the subsequent purification efficiency and effect; the adsorption layer is also inconvenient to maintain and replace.

[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a high-efficiency asphalt fume recovery and purification device, including a purification box and a fan. The fan is located in the middle of the purification box. A partition is provided in the middle of the purification box. A guide ring plate is provided through the middle of the partition. The fan is located at the through point of the guide ring plate. The purification box below the partition is an air inlet chamber with an inlet. An umbrella plate is provided above the fan in the air inlet chamber. A waste heat recovery component that can drive asphalt fumes to condense into oil is provided inside the umbrella plate. A receiving cavity is provided circumferentially on the guide ring plate above the partition. An exhaust pipe is provided at the top of the purification box. An adsorption plate is detachably provided inside the exhaust pipe.

[0005] Furthermore, the umbrella plate is a symmetrically arranged inclined plate, and the bottom wall of the inclined plate is provided with several guide grooves.

[0006] Furthermore, the waste heat recovery assembly includes a cooling pipe that runs through the umbrella plate and the purification box, the cooling pipe being spirally arranged and circulated by a circulating pump.

[0007] Furthermore, an oil drain pipe is provided at the bottom of the receiving cavity, and a valve plate is provided inside the oil drain pipe.

[0008] Furthermore, the adsorption plate is provided with a pull rod, the discharge pipe is provided with a through hole that cooperates with the adsorption plate, the discharge pipe is provided with a mounting plate at the through hole, a sliding rod is slidably provided on the mounting plate, a limiting plate is provided at the bottom of the sliding rod, a spring is provided outside the sliding rod between the mounting plate and the limiting plate, and a top of the sliding rod is provided to abut against the pull rod so that the adsorption plate and the discharge pipe are sealed together.

[0009] Furthermore, the discharge pipe is provided with limiting strips on both sides of the adsorption plate, and limiting blocks that slide with the adsorption plate in the gap between the relative limiting strips.

[0010] The advantages of this utility model compared with the prior art are as follows:

[0011] A fan guides asphalt fumes from the inlet into the air intake chamber, then through the guide ring plate into the collection chamber above the baffle. The waste heat recovery components on the umbrella plate facilitate the recovery of high-temperature fumes from the asphalt fumes, avoiding the energy waste caused by directly filtering the asphalt fumes through the filter components. At the same time, after the asphalt fumes come into contact with the umbrella plate, the oil and gas in them cool down and condense, and are then collected in the collection chamber, while the remaining waste gas is adsorbed by the adsorption plate. The detachable design of the adsorption plate facilitates its maintenance and replacement. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Combined with appendix Figure 1 Appendix Figure 2 and attached Figure 3A high-efficiency asphalt fume recovery and purification device includes a purification box 1 and a blower 2. The blower 2 is located in the middle of the purification box 1. A partition 3 is provided in the middle of the purification box 1. A guide ring plate 4 is provided at the through-hole of the partition 3. The blower 2 is located at the through-hole of the guide ring plate 4. The purification box 1 below the partition 3 is an air inlet chamber 5 with an inlet 7. An umbrella plate 6 is provided above the blower 2 in the air inlet chamber 5. A receiving chamber 9 is provided around the guide ring plate 4 above the partition 3. An oil drain pipe 14 is provided at the bottom of the receiving chamber 9. A valve plate is provided inside the oil drain pipe 14. An exhaust pipe 22 is provided at the top of the purification box 1. An adsorption plate 10 is provided inside the exhaust pipe 22.

[0020] By starting the fan 2, the fan 2 guides the asphalt fumes to form a fixed guide channel. The asphalt fumes are introduced into the air intake chamber 5 from the inlet 7, and then into the collection chamber 9 through the through-hole at the top of the guide ring plate 4. The umbrella plate 6 can block the asphalt fumes and facilitate the guidance of the asphalt fumes. Finally, the asphalt fumes are discharged from the discharge pipe 22. The adsorption plate 10 can adsorb and filter the non-condensable waste gas in the asphalt fumes.

[0021] Combined with appendix Figure 2 and attached Figure 4 The umbrella plate 6 is an inclined plate 11 arranged symmetrically. The bottom wall of the inclined plate 11 is provided with a number of guide grooves 12. The umbrella plate 6 is provided with a waste heat recovery component 8 that can drive asphalt fumes to condense into oil. The waste heat recovery component 8 includes a cooling pipe 13 that runs through the umbrella plate 6 and the purification box 1. The cooling pipe 13 is coiled and is driven by a circulation pump to circulate.

[0022] High-temperature asphalt fumes rise and come into contact with umbrella plate 6. The circulating pump drives domestic hot water to circulate in cooling pipe 13. The domestic hot water can then be used for heating and other purposes, making it easy to recycle. After the asphalt fumes come into contact with umbrella plate 6, which has a high thermal conductivity, they cool down and condense. Then, the oil and gas in them are guided from guide groove 12 to collection cavity 9.

[0023] Combined with appendix Figure 4 and attached Figure 5 An adsorption plate 10 is detachably and sealed inside the discharge pipe 22. Limiting strips 21 are provided on both sides of the adsorption plate 10 in the discharge pipe 22. The gap between the relative limiting strips 21 is slidably engaged with the adsorption plate 10. A pull rod 15 is provided on the adsorption plate 10. A through hole is provided on the discharge pipe 22 to cooperate with the adsorption plate 10. An installation plate 16 is provided at the through hole in the discharge pipe 22. A sliding rod 17 is slidably passed through the installation plate 16. A limiting plate 18 is provided at the bottom of the sliding rod 17. A spring 19 is provided outside the sliding rod 17 between the installation plate 16 and the limiting plate 18. A limiting block 20 is provided at the top of the sliding rod 17 to abut against the pull rod 15 so that the adsorption plate 10 and the discharge pipe 22 are sealed together.

[0024] The non-condensable waste gas in the asphalt fumes is discharged through the gap between the umbrella plate 6 and the guide ring plate 4, and then upward through the exhaust pipe. After being adsorbed by the adsorption plate 10, it is avoided from being directly discharged and causing pollution to the environment.

[0025] Align the adsorption plate 10 with the through hole and drive the adsorption plate 10 along the through hole between the top and bottom limiting strips 21. Since the limiting block 20 is a triangular or trapezoidal block, the adsorption plate 10 drives the limiting block 20 to slide downward through the slide rod 17, causing the spring 19 to stretch and store force until the adsorption plate 10 no longer contacts the limiting block 20. As the adsorption plate 10 continues to be driven, the back side of the pull rod 15 abuts against the limiting block 20. Since the limiting block 20 is inclined on one side, under the stretching and storing force of the spring 19, the inclined surface of the limiting block 20 abuts against the pull rod 15, so that the pull rod 15 drives the adsorption plate 10 to always be in a sealed fit with the discharge pipe 22.
