Description

Technical Field

[0001] The present invention relates to the technical field of asphalt processing, in particular to an exhaust gas purification and treatment device for asphalt processing. Background Art

[0002] Asphalt is a black or dark mixture, mainly composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is in the form of solid, semi-solid or viscous liquid at room temperature. In road engineering, asphalt can be used to pave various roads, such as ordinary roads, highways, airport runways, etc., which can make the road surface have good wear resistance, skid resistance and durability. In waterproofing engineering, asphalt can be used for waterproofing of roofs, floors and underground structures, such as making waterproof membranes and waterproof coatings, which effectively prevent water penetration. In anti-corrosion engineering, asphalt plays an anti-corrosion role for materials such as wood and steel, extending their service life. Asphalt can also be used to manufacture coatings, plastics, rubber and other industrial products, as well as as lining and covering layers of landfills, railway protective coatings, automotive undercoatings, etc.

[0003] Asphalt processing is the process of treating raw asphalt through a series of physical and chemical methods to make it meet the performance requirements of different application scenarios. During the asphalt processing process, a large amount of waste gas will be generated due to the heating of raw materials, chemical reactions and volatilization. The composition of these waste gases is complex and is not only harmful to the health of operators, but may also cause environmental pollution.

[0004] In the existing technology, an exhaust gas purification device is added to one side of the filtration processing device. The exhaust gas purification device purifies the exhaust gas and then discharges the purified gas, reducing environmental pollution. However, the exhaust gas generated by asphalt processing contains grease (such as heavy hydrocarbons and grease impurities in asphalt smoke), and grease substances usually have the characteristics of high viscosity and easy condensation. During the exhaust gas transportation process, if the exhaust gas dissipates heat and cools down, the grease will condense from gaseous or misty state to liquid or solid state, and adhere to the inner wall of the pipe. After long-term accumulation, the cross-sectional area of ​​the pipe will gradually shrink, or even be completely blocked. After the grease moves with the exhaust gas to the filter component (such as filter plate, filter screen, filter material, adsorbent, etc.) area inside the exhaust gas purification treatment device, the grease will adhere to the surface of the filter component, blocking its pores, causing the filtration resistance to rise sharply, reducing the airflow rate, and reducing the exhaust gas purification treatment efficiency.

[0064] Second embodiment

[0065] An exhaust gas purification device for asphalt processing, please refer to Figure 1 - Figure 15 Based on the first embodiment, the difference from the first embodiment is that multiple groups of support blocks 39 are installed on the inner wall of the exhaust gas treatment device 2, an inner cylinder 36 is installed inside the exhaust gas treatment device 2, and multiple groups of mounting blocks 38 are installed at the bottom of the inner cylinder 36. The multiple groups of mounting blocks 38 are respectively connected to the multiple groups of support blocks 39 with bolts. An inner tube 37 is provided at one end of the inner cylinder 36, and one end of the inner tube 37 is connected to the intake pipe 3. The exhaust gas enters the inner cylinder 36 through the intake pipe 3 and the inner tube 37, and the exhaust gas is displaced toward the upper end in the inner cylinder 36.

[0066] Please refer to Figure 11-15 The bottom end of the movable disk 23 is conical, and the exhaust gas contacts the bottom end of the movable disk 23. The movable disk 23 performs preliminary treatment on the exhaust gas, and the gap between the movable disk 23 and the upper end of the inner cylinder 36 is small. Only a small amount of exhaust gas will pass directly through the gap, and most of the exhaust gas passes through the bottom end of the movable disk 23 for preliminary treatment. The outer wall of the scraper 24 is movably connected to the outer wall of the bottom end of the movable disk 23. When the movable disk 23 is rotating, the scraper 24 cleans the grease attached to the bottom end of the movable disk 23. After the initial treatment of the exhaust gas, the exhaust gas enters the upper end area of ​​the movable disk 23 through the gap between the movable disk 23 and the upper end of the inner cylinder 36. Multiple groups of water spray heads 26 spray water to the upper end of the movable disk 23. When the movable disk 23 is rotating, a water curtain is formed. The exhaust gas undergoes secondary purification through the water curtain to absorb the residual grease inside the exhaust gas. After absorbing the grease, the water flow flows to the sewage outlet 33 through the outer wall of the inner cylinder 36.

[0067] The working principle of the present invention is as follows: when a worker uses the device to purify the exhaust gas generated after asphalt processing, the exhaust gas generated by the asphalt processing device 1 enters the exhaust gas treatment device 2 through the air intake pipe 3, and then the worker starts the drive motor 4, which drives the drive shaft 5 to rotate, thereby driving the drive bevel gear 6 to rotate. The drive bevel gear 6 is meshed and connected with the transmission bevel gear 8. The transmission bevel gear 8 rotates, thereby driving the transmission shaft 7 to rotate;

[0068] When the transmission shaft 7 rotates, it drives the two sets of transmission gears 9 to rotate, and the two sets of transmission gears 9 are respectively meshed with the two sets of movable gears 11. The two sets of movable gears 11 rotate, driving the two sets of first movable rings 10 to rotate, thereby driving the cleaning piece 12 to rotate. The outer wall of the cleaning piece 12 is attached to the inner wall of the intake pipe 3. After the exhaust gas passes through the inside of the intake pipe 3, the grease contained in the exhaust gas adheres to the inner wall of the intake pipe 3. The cleaning piece 12 rotates, and the cleaning piece 12 cleans the grease adhered to the inner wall of the intake pipe 3. The intake 3 is inclined, so that the grease flows into the interior of the exhaust gas treatment device 2. At the same time, the cleaning piece 12 is spirally arranged, which further improves the grease cleaning effect on the inner wall of the intake pipe 3.

[0069] When the two sets of movable gears 11 rotate, one set of movable gears 11 is meshed and connected with the connecting gear 14, so the connecting gear 14 rotates, driving the connecting shaft 13 to rotate, thereby driving the connecting bevel gear 15 to rotate, the connecting bevel gear 15 is meshed and connected with a set of first movable bevel gears 17, a set of first movable bevel gears 17 rotates, thereby driving the movable shaft 16 to rotate, and then driving another set of first movable bevel gears 17 to rotate, the other set of first movable bevel gears 17 is meshed and connected with a set of limiting bevel gears 19, a set of limiting bevel gears 19 rotates, thereby driving the limiting shaft 18 to rotate, and then driving another set of limiting bevel gears 19 to rotate, the other set of limiting bevel gears 19 is meshed and connected with the second movable bevel gear 21, the second movable bevel gear 21 rotates, thereby driving the second movable ring 20 to rotate, thereby driving multiple sets of connecting rods 22 to rotate, and then driving the movable disk 23 to rotate;

[0070] When the drive motor 4 is started, the water pump at the outer end is started at the same time, and the water flows through the water inlet pipe 28 into the water collecting pipe 27, and then flows through the water collecting pipe 27 into the water collecting ring 25, and then multiple groups of water spray heads 26 spray the water, and the water spraying direction is all the upper end of the movable plate 23;

[0071] When the movable disk 23 rotates, water is simultaneously sprayed to the upper end of the movable disk 23, and the movable disk 23 disperses the water to the area between the movable disk 23 and the second movable ring 20. The water flows through the area between the movable disk 23 and the second movable ring 20 and falls to the bottom end of the exhaust gas treatment device 2. After the exhaust gas enters the exhaust gas treatment device 2, the exhaust gas flows toward the air outlet 29. The exhaust gas flows toward the air outlet 29 through the area between the movable disk 23 and the second movable ring 20. The water absorbs the grease in the exhaust gas, so that the grease in the exhaust gas falls to the bottom end of the exhaust gas treatment device 2 with the water.

[0072] When the water flow is sprayed onto the upper end of the movable disk 23, the water flow cools the movable disk 23, so that when the exhaust gas contacts the bottom end of the movable disk 23, the temperature of the exhaust gas is lowered, causing the grease inside the exhaust gas to adhere to the bottom end of the movable disk 23. The movable disk 23 continues to rotate, and the scraper 24 cleans the grease adhered to the bottom end of the movable disk 23, so that the grease adhered to the bottom end of the movable disk 23 falls to the bottom end of the exhaust gas treatment device 2, further improving the grease cleaning effect inside the exhaust gas;

[0073] When the grease flows with the water to the bottom of the exhaust gas treatment device 2, the grease and the wastewater adsorbed with the grease enter the interior of the sewage pipe 34 through the sewage outlet 33. One end of the sewage pipe 34 is connected to an external sewage treatment device. The grease and the wastewater adsorbed with the grease enter the interior of the sewage treatment device through the sewage pipe 34, and the sewage treatment device treats the sewage.

[0074] After the grease inside the exhaust gas is cleaned, the exhaust gas enters the exhaust pipe 30 through the exhaust port 29, and then enters the exhaust gas purification device 31 through the exhaust pipe 30. The exhaust gas purification device 31 purifies the exhaust gas, and the purified gas is discharged through the exhaust pipe 32.
