Description

Technical Field

[0001] The present application relates to the technical field of carbon emission treatment equipment, and in particular to a device for treating carbon emissions from aggregates in an asphalt mixing station. Background Art

[0002] Asphalt mixture is a general term for a mixture of mineral materials and asphalt binder. It is a composite material, mainly composed of asphalt, coarse aggregate, fine aggregate, mineral powder, and some also add polymers and wood cellulose; these materials of different quality and quantity are mixed to form different structures and have different mechanical properties. Asphalt mixture is widely used in various types and levels of road construction, and is often mass-produced by asphalt mixing plants. It is a traditional industry with high investment, high emissions and high pollution. When heated during the aggregate mixing process, a large amount of harmful gases such as nitrogen oxides, methane gas and carbon dioxide will be generated. Therefore, it is also an industry with relatively serious carbon emissions. At a time when sustainable development is advocated, the problem of carbon emissions in the aggregate process of asphalt mixing plants has gradually attracted people's attention.

[0003] At present, the treatment of carbon emission waste gas generated during the aggregate mixing of asphalt mixing stations is generally carried out by first spraying and purifying dust, then filtering nitrogen oxides, then burning alkane gas to convert it into carbon dioxide, and finally reacting with sodium peroxide solution to convert carbon dioxide into oxygen for safe discharge. This is a relatively common and cost-effective treatment method, but the solution in the sodium peroxide solution reaction tank generally needs to be prepared in advance, which takes up a lot of man-hours. The solubility of sodium peroxide in water is small and the preparation efficiency is low. Therefore, stirring is required during the preparation process, but the preparation process is difficult to carry out in a sealed environment.

The combustion chamber 30 has a blowing function, which is convenient for blowing the carbon dioxide exhaust gas after the combustion of the alkane exhaust gas into the reaction tank 40.

[0030] According to some embodiments of the present application, Figure 5-Figure 8As shown, the reaction tank 40 is connected to the combustion chamber 30; a second water tank 41 is provided on one side of the outside of the reaction tank 40, and the second water tank 41 is connected to the reaction tank 40 through a connecting pipe 411, and the connecting pipe 411 is connected to the top of the reaction tank 40, and a second liquid pump 412 is provided on the connecting pipe 411, and a nozzle 413 is provided at the end of the connecting pipe 411, and the nozzle 413 is arranged at the upper part of the central axis inside the reaction tank 40.

[0031] The combustion chamber 30 is connected to the reaction tank 40 through the first delivery pipe 42 and the second delivery pipe 43 respectively. The first delivery pipe 42 is connected from the upper side of the reaction tank 40 along the tangential direction; the second delivery pipe 43 is connected from the lower side of the reaction tank 40. A side agitator 44 is arranged on the outer side of the lower part of the reaction tank 40.

The carbon dioxide waste gas is first input from the upper side of the reaction tank 40 through the first delivery pipe 42, and the sodium peroxide powder is input through the screw feeder 50 and scattered. The screw feeder 50 itself and the joint with the reaction tank 40 are sealed to prevent the carbon dioxide in the air from reacting with the sodium peroxide powder being transported, thereby reducing additional losses. The nozzle 413 sprays Input (hot) water, the first delivery pipe 42 is connected from the upper side of the reaction tank 40 along the tangential direction, which will increase the blowing range of the input carbon dioxide waste gas in the reaction tank 40, and also facilitate the formation of a stronger vortex in the reaction tank 40, so that the sodium peroxide powder can undergo a more sufficient reaction before falling into the water, and at the same time dissolve with the sprayed (hot) water to form a sodium peroxide solution that falls into the lower part of the reaction tank 40, and at the same time start the side agitator 44 to stir the sodium peroxide solution to make it fully dissolved. After the solution page reaches a certain height, the second delivery pipe 43 can be opened to input the second carbon dioxide waste gas from the lower part of the reaction tank 40 into the sodium peroxide solution for further reaction, and the carbon dioxide waste gas input from the two routes can be fully reacted and removed, and converted into oxygen to achieve safe discharge.

[0032] According to some embodiments of the present application, Figure 5-Figure 9As shown, when sodium peroxide powder is input into the reaction tank 40 through the screw feeder 50, if it is scattered into the reaction tank 40 only by free fall, the scattering range is extremely limited, which is extremely unfavorable for expanding the contact surface with the blown-in carbon dioxide waste gas, and further unfavorable for the reaction efficiency and quality of the sodium peroxide powder and the carbon dioxide waste gas when suspended in the air, and is also unfavorable for rapid and sufficient dissolution with the water sprayed into the reaction tank 40 to form a sodium peroxide solution.The scattering mechanism 60 is arranged at the top and inside of the reaction tank 40. The scattering mechanism 60 includes a feeding component 61 and a scattering component 62. The feeding component 61 is movably connected to the top of the reaction tank 40. The feeding port of the feeding component 61 is connected to the discharge port of the spiral feeder 50. The scattering component 62 is rotatably arranged at the central axis of the top of the reaction tank 40. The feeding component 61 is connected to the scattering component 62. The feeding component 61 includes a connecting column 611, a vibration motor 612, a spring 613 and a feeding box 614. The connecting column 611 slides through the top of the reaction tank 40. The vibration motor 612 is detachably arranged at the top of the connecting column 611. The connecting column 611 penetrates the spring 613. The spring 613 and the feeding box 614 The two ends of 13 are respectively fixedly connected to the top of the connecting column 611 and the outer side of the top of the reaction tank 40, the material box 614 is fixedly arranged on one side of the lower end of the connecting column 611 and arranged inside the reaction tank 40, and the upper side of the material box 614 is connected to the discharge port of the spiral feeder 50 through the corrugated pipe 615. The scattering component 62 includes a connecting pipe 621, a reduction motor 622, a circular plate 623 and a rotating scattering bin 624. The connecting pipe 621 is hollow and its upper end is fixedly connected to the inner top side of the central axis of the reaction tank 40. The middle part of the upper side of the circular plate 623 is fixedly connected to the lower end of the connecting pipe 621. The reduction motor 622 is arranged at the top of the top of the reaction tank 40 and its output shaft rotates and penetrates the top of the reaction tank 40. The output shaft of the reduction motor 622 passes through the connecting pipe 621 and the circular plate 623, and its lower end is fixedly connected to the middle part of the lower side of the rotating dispersing bin 624. The inner edge of the upper opening of the rotating dispersing bin 624 can be rotatably connected to the outer edge of the circular plate 623. The rotating dispersing bin 624 is arranged above the nozzle 413; the rotating dispersing bin 624 is connected to the feeding box 614 through the hose 616 via the circular plate 623. A plurality of dispersing ports 6241 are evenly opened on the circumference of the rotating dispersing bin 624. When the sodium peroxide powder is input through the spiral feeder 50, the appropriate input speed is controlled, and the vibration motor 612 is started to drive the connecting column 611 to vibrate up and down under the elastic force of the spring 613, so that the sodium peroxide powder entering the feeding box 614 is The sodium peroxide powder is shaken into the rotating dispersing bin 624 through the hose 616 and the circular plate 623, and the reduction motor 622 is started to drive the rotating dispersing bin 624 to rotate. The sodium peroxide powder shaken into the rotating dispersing bin 624 will be scattered through the dispersing port 6241 under the action of centrifugal force, and the scattered sodium peroxide powder will be blown and stirred by the blown-in carbon dioxide waste gas, and after a direct reaction with the gas in the first step, it will fall and dissolve with the water sprayed by the nozzle 413, and fall into the lower part of the reaction tank 40, and at the same time cooperate with the stirring of the side agitator 44 to form a sodium peroxide solution so as to react with the next carbon dioxide waste gas input through the second conveying pipe 43, and further convert the carbon dioxide into safe oxygen for discharge.The above method can significantly and effectively expand the scattering range of sodium peroxide powder, which is beneficial to expand the contact surface with the blown carbon dioxide waste gas, and is beneficial to the reaction efficiency and quality of sodium peroxide powder and carbon dioxide waste gas when suspended in the air. It is also convenient to quickly form sodium peroxide solution and fall into the reaction tank 40, so as to achieve simultaneous reaction with carbon dioxide waste gas in the form of solution and powder, and further improve the reaction efficiency and quality.

[0033] Specifically, the working principle of the treatment device for carbon emission of aggregates in the asphalt mixing station is as follows: when in use, the waste gas generated in the aggregate process of the asphalt mixing station is first input into the primary treatment tank 10, and the first water tank 11 is generally filled with cold water. After being sprayed and input from the top of the primary treatment tank 10 through the first liquid pump 112 through the spray pipe 111, the waste gas generated in the aggregate process of the input asphalt mixing station can be sprayed in advance to remove most of the more obvious dust impurities; then it is input into the nitrogen oxide treatment box 20 to filter and remove nitrogen oxides, and then it is input into the combustion chamber 30 to burn the alkane waste gas into water and carbon dioxide. The combustion chamber 30 has a blast The function is to blow the carbon dioxide waste gas after the combustion of the alkane waste gas into the reaction tank 40, and after the combustion is completed, it is input into the reaction tank 40 in two ways, upper and lower. At the same time, sodium peroxide is input into the reaction tank 40 through the spiral feeder 50, and the appropriate input speed is controlled. The vibration motor 612 is started to drive the connecting column 611 to vibrate up and down under the elastic force of the spring 613, and the sodium peroxide powder entering the feeding box 614 is shaken into the rotating dispersing bin 624 through the hose 616 and the circular plate 623. At the same time, the reduction motor 622 is started to drive the rotating dispersing bin 624 to rotate. The sodium peroxide powder shaken into the rotating dispersing bin 624 will be scattered through the dispersing port 6241 under the action of centrifugal force. The screw feeder 50 itself and the joint with the reaction tank 40 are sealed to prevent the carbon dioxide in the air from reacting with the sodium peroxide powder being transported, thereby reducing additional losses. The first conveying pipe 42 is connected to the upper side of the reaction tank 40 along the tangential direction, which will increase the blowing range of the input carbon dioxide waste gas in the reaction tank 40, and also facilitate the formation of a stronger vortex in the reaction tank 40, so that the sodium peroxide powder has undergone a more sufficient reaction before falling into the water, and then the nozzle 413 below the falling and rotating distribution bin 624 sprays the input (hot) water to dissolve to form a sodium peroxide solution that falls into the lower part of the reaction tank 40, and at the same time, the side agitator 44 is turned on to stir the sodium peroxide solution. The sodium peroxide solution is used to fully dissolve it. After the solution page reaches a certain height, the second carbon dioxide waste gas input from the lower part of the reaction tank 40 through the second delivery pipe 43 can be opened to enter the sodium peroxide solution for further reaction. This can significantly and effectively expand the scattering range of the sodium peroxide powder, which is beneficial to expanding the contact surface with the blown carbon dioxide waste gas, and is beneficial to the reaction efficiency and quality of the sodium peroxide powder and the carbon dioxide waste gas when suspended in the air. It is also convenient to quickly form a sodium peroxide solution and fall into the reaction tank 40, so as to achieve simultaneous reaction with the carbon dioxide waste gas in the form of solution and powder. The carbon dioxide waste gas input in two ways can be fully reacted and removed, and converted into oxygen to achieve safe discharge.Not only can sodium peroxide powder be input into the sodium peroxide reaction tank 40 while ensuring a relatively sufficient reaction with the carbon dioxide waste gas input in a branch route, but the preparation of the sodium peroxide solution can also be completed, eliminating the step of specially preparing the sodium peroxide solution, saving a lot of man-hours, reducing the additional loss of sodium peroxide, improving the removal efficiency and quality of carbon dioxide waste gas, achieving safe treatment and discharge of waste gas in the aggregate process of the asphalt mixing station, significantly reducing carbon emissions, and actively achieving a balance between environmental and economic benefits.
