Description

Technical Field

[0001] The invention relates to the technical field of asphalt tail gas treatment, and in particular to a flue gas incineration purification device. Background Art

[0002] Asphalt mixture regeneration technology is a technology for recycling waste asphalt mixture. Thermal regeneration technology is one of the most widely used regeneration processes. One of the most widely used methods of existing regeneration technology is to add waste asphalt mixture to new materials, new asphalt and other raw materials in a certain proportion and mix them together to form finished materials. This method mainly consists of a set of raw equipment and a set of regeneration equipment, and the two sets of equipment share a flue gas purification system.

[0003] Since the tail gas generated after heating the waste asphalt mixture contains a variety of complex components such as dust and asphalt fume, the regenerated tail gas must be effectively treated, otherwise it will cause serious pollution to the environment. In order to clean the dust and asphalt fume in the regenerated tail gas, the regenerated tail gas treatment method of this regeneration and original combination equipment is to send the regenerated tail gas to the original drying drum for secondary combustion, and then filter the dust through the original bag dust collector to finally meet the qualified emission standards.

[0004] However, the flame area generated by the burners of the regeneration device and the original drum is small, the treatment efficiency of asphalt smoke is low, and there is a problem of unclean smoke treatment. Therefore, in the existing smoke purification system, an incinerator is added to fully burn the smoke and recover the waste heat generated by the smoke to the original drum through a heat exchanger for reuse to reduce energy waste. However, the flame area generated by the burner in the existing incinerator is still limited. When the smoke flow rate entering the furnace is large, the flame area may not be able to completely cover the smoke, thereby affecting the combustion effect, resulting in incomplete combustion of the smoke, and ultimately causing the exhaust gas to still contain components that are harmful to the health of workers.

[0007] The present invention is further configured such that a plurality of the burners are obliquely arranged on a mounting frame, with the flame ports of the burners facing the air outlet of the incinerator and inclined toward the center of the exhaust gas flow port, so that the flames ejected from the plurality of burners have a conical structure.

[0008] The present invention is further configured such that the air inlet and the air intake are arranged at the same end of the incinerator and the two are symmetrically arranged, respectively located on the peripheral sides of the incinerator.

[0011] The present invention is further configured such that one end of the flue gas duct extends toward the bottom of the purification chamber to form an exhaust pipe, and one end of the steam duct extends into the purification chamber to form a steam nozzle. The steam nozzle is annular, horizontally arranged on the inner wall of the purification chamber and located above the exhaust pipe, and a plurality of steam ports are arranged on the inner wall of the steam nozzle.

[0012] The present invention is further configured such that the air outlet is located at the top of the purification chamber, which is connected to a temperature control pipe, in which an air control valve and a temperature sensor electrically connected to the air control valve are arranged, and the temperature sensor is used to detect that when the temperature in the temperature control pipe reaches a set temperature, the air control valve is controlled to transport smoke into the native drum.

[0013] The present invention is further configured such that a condensation pan located at the air outlet is provided on the inner wall of the purification chamber, the condensation pan is spaced apart from the top of the purification chamber, a flue gas channel is formed therebetween, a cooling device is provided in the condensation pan, the cooling device is used to reduce the temperature of a side of the condensation pan facing the bottom of the purification chamber, and the cooling device is electrically connected to a temperature sensor.

[0030] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of the present invention.

[0031] like Figure 1-5 As shown, this embodiment discloses a flue gas incineration purification device, comprising an incinerator 1 with an air inlet 2, an air outlet 3 and an air inlet 4, the air inlet 2 of the incinerator 1 is connected to the exhaust gas outlet of the flue gas storage device 5, and the air outlet 3 thereof is connected to the raw drum 6;

[0032] Among them Figure 1 As shown, the flue gas storage device 5 is an exhaust gas storage box, and its feed port is connected to the regeneration drying device. The regeneration drying device includes a regeneration drum 7. The air inlet end of the regeneration drum 7 is connected to a hot air furnace 8. The end of the hot air furnace 8 away from the regeneration drum 7 is connected to a burner 11. The burner 11 can burn and heat the air entering the hot air furnace 8, so as to achieve drying of the material in the regeneration drum 7. A circulating fan 9 is also connected to the air inlet end of the hot air furnace 8. The circulating fan 9 is connected to the control system of the asphalt drying system. The air inlet of the circulating fan 9 is connected to the exhaust gas outlet of the exhaust gas storage box through a pipeline, so that the generated exhaust gas can be sent into the hot air furnace 8 for secondary combustion, thereby reducing the impurity content in the exhaust gas generated by the regeneration device.

[0033] Another waste gas outlet of the waste gas storage box is connected to the air inlet 2 of the incinerator 1, and the air outlet 3 of the incinerator 1 is connected to the air inlet end of the primary drum 6. The air outlet end of the primary drum 6 is connected to the waste gas dust removal equipment 16, and the waste gas dust removal equipment 16 is connected to the circulating fan 9. The circulating fan 9 can guide the flue gas burned by the incinerator 1 to pass through the primary drum 6, dry the material in the primary drum 6, and guide the flue gas generated in the primary drum 6 to be processed and purified by the dust removal equipment and then discharged into the air. An electric damper connected to the control system can be arranged between the air outlet end of the primary drum 6 and the dust removal equipment. The electric damper can control the air volume of the smoke in the primary drum 6 entering the dust removal equipment, thereby controlling the time the smoke stays in the primary drum 6.

[0034] like Figure 1-2 As shown, the air inlet 2 and the air outlet 3 are respectively located at the two ends of the incinerator 1, and a mounting frame 10 located between the air inlet 2 and the air outlet 3 is arranged in the incinerator 1. An exhaust gas flow port is arranged in the center of the mounting frame 10, and a plurality of burners 11 are distributed on the circumference thereof. The burners 11 are obliquely arranged on the mounting frame 10, and the flame ports of the burners 11 are oriented toward the air outlet 3 of the incinerator 1 and inclined toward the center of the exhaust gas flow port, so that the flames ejected by the plurality of burners 11 are in a conical structure; when the exhaust gas enters the incinerator 1 through the air inlet 2, the exhaust gas flows through the flow port, is fully covered by the conical flame and burnt at high temperature, and the flame area covers the entire exhaust gas flow path. The obliquely arranged burner 11 can make the flame concentrate toward the center, ensuring that the exhaust gas is fully in contact with the high-temperature flame in a short time, achieving the effect of complete incineration; compared with the existing incinerator 1, the conical flame gathering design greatly increases the contact area between the flue gas and the flame, avoiding the problem of limited flame area in the traditional incinerator 1, and ensuring that the harmful components in the flue gas are fully incinerated. In this way, the incinerated flue gas can directly enter the primary drum 6 to dry the impurities in the primary drum 6, effectively improving the heat recovery efficiency and saving energy.

[0035] The air inlet 4 and the air inlet 2 are arranged at the same end of the incinerator 1 and are symmetrically arranged, respectively located on the surrounding sides of the incinerator 1; and through the symmetrical arrangement of the air inlet 4 and the air inlet 2, the air and the exhaust gas can generate turbulence after entering the incinerator 1, so as to achieve mixing of the air and the exhaust gas, thereby improving the incineration effect.

[0036] like Figure 2-3As shown, an incineration chamber 100 and a purification chamber 101 are provided in the incinerator 1, an air inlet 2, an air inlet 4 and a burner 11 are located in the incineration chamber 100, an air outlet 3 is located in the purification chamber 101, and a purification mechanism is provided in the purification chamber 101 for purifying the exhaust gas; a heat exchange pipe 102 is provided between the incineration chamber 100 and the purification chamber 101, the heat exchange pipe 102 comprises a cylindrical mounting shell 112, a spiral flue gas pipe 122 is provided in the middle of the mounting shell 112, a heat absorption chamber 132 is formed between the flue gas channel 13 and the mounting shell 112, a water inlet 142 is provided at the bottom of the heat absorption chamber 132, a steam pipe 152 is provided at the top of the heat absorption chamber 132, the steam pipe 152 connects the heat absorption chamber 132 and the purification chamber 101, a drain outlet 162 with a one-way valve is also connected to the bottom of the purification chamber 101, and the drain outlet 162 is connected to a sewage collection tank 172.

[0037] By setting a spiral heat exchange pipe 102 between the incineration chamber 100 and the purification chamber 101, when the flue gas passes through the flue gas pipe 122, the heat absorption chamber 132 outside the pipe introduces cold water through the water inlet 142, and the water in the heat absorption chamber 132 gradually absorbs heat and generates water vapor by exchanging heat with the high-temperature flue gas in the flue gas pipe 122. The generated water vapor enters the purification chamber 101 through the steam pipe 152 to cool and purify the flue gas, and the water vapor will condense into water after being attached to the impurities in the flue gas, and the water will fall to the bottom of the purification chamber 101 and flow to the sewage collection tank 172 through the drain port 162 for recycling.

[0038] When flue gas is purified and cooled by water vapor, the cooling process is gentler and more controllable than directly discharging the flue gas into water. The cooling effect of water vapor is mainly achieved through evaporative cooling and heat absorption, which can slowly reduce the flue gas temperature without causing drastic temperature difference shocks. This gradual cooling method is more conducive to protecting equipment and reducing the damage of thermal stress to the system.

[0039] Moreover, when water vapor cools the flue gas, it usually brings less moisture, and the condensed moisture is also easy to control and discharge. When water vapor is sprayed in the purification chamber 101, the spraying amount can be accurately controlled to avoid excessive moisture accumulation. Moisture mainly plays a role in cooling and capturing particulate matter in the flue gas, and the increase in humidity is limited.

[0040] In addition, using water vapor to cool the flue gas does not allow pollutants in the flue gas to come into direct contact with water, so it does not cause serious water pollution. The condensed water vapor can be processed by a purification device, and the treated water can be recycled or discharged, reducing the burden on the environment.

[0041] At the same time, water vapor can cool the flue gas while creating a wet dust removal effect, taking away some particulate matter, especially tiny particulate matter (such as PM2.5) through steam condensation. In addition, water vapor can also enhance the chemical reaction between gases, helping to remove some gaseous pollutants in the flue gas, such as SOx, NOx, etc. Compared with direct water treatment, water vapor can be more fully mixed with the flue gas, improving the effect of capturing particulate matter and absorbing harmful gases.

[0042] Finally, when using water vapor to cool and treat flue gas, less water is required, and the condensed water can be recycled and reused, thereby reducing the water consumption of the entire system. This makes the system more energy-efficient and environmentally friendly, reducing dependence on and waste of water resources.

[0043] This design improves the heat exchange efficiency by combining the spiral heat exchange pipe 102 with the heat absorption chamber 132, and realizes the effective recovery and reuse of waste heat. By recovering the heat of the flue gas to generate water vapor, not only the temperature of the flue gas is effectively reduced, and the high-temperature flue gas is prevented from directly entering the primary drum 6 and causing damage to the primary drum 6 or the pipe, but also the water vapor plays a role in cooling and capturing particulate matter in the purification chamber 101, further improving the purification efficiency of the flue gas and reducing the contamination of the materials in the primary drum 6 by impurities in the flue gas. In addition, the use of waste heat recovery reduces energy waste and improves the energy efficiency of the overall system.

[0044] like Figure 5 As shown, one end of the flue gas duct 122 extends to the bottom of the purification chamber 101 to form an exhaust pipe 103, and one end of the steam duct 152 extends into the purification chamber 101 to form a steam nozzle 104. The steam nozzle 104 is annular and horizontally arranged on the inner wall of the purification chamber 101 and located above the exhaust pipe 103. A plurality of steam ports 105 are arranged on the inner wall of the steam nozzle 104, and the steam nozzle 104 can be arranged at the steam port 105 to realize the injection of steam.

[0045] Water vapor enters the purification chamber 101 through the steam pipe 152, and is sprayed into the purification chamber 101 through the annularly arranged steam nozzle 104. The steam nozzle 104 is arranged above the exhaust pipe 103, and the sprayed water vapor can fully contact the flue gas, and the water vapor plays a role in cooling and capturing particles in the flue gas. The steam nozzle 104 ensures that the water vapor covers the entire flue gas flow area through evenly distributed nozzles, so that the water vapor can fully contact the flue gas, playing a cooling and particle capture effect. This method can effectively reduce suspended particles and dust in the flue gas, reduce solid pollutants in emissions, and further improve the flue gas purification effect. At the same time, water vapor also has a certain dust removal effect, can capture smaller particles, and improve the overall emission quality.

[0046] like Figure 3-4As shown, the air outlet 3 is located at the top of the purification chamber 101, which is connected to a temperature control pipe 106, and an air control valve 107 and a temperature sensor 108 electrically connected to the air control valve 107 are arranged in the temperature control pipe 106. The temperature sensor 108 is connected to the control system, and is used to detect that when the temperature in the temperature control pipe 106 reaches the set temperature, the air control valve 107 is controlled to transport the flue gas into the primary drum 6; the temperature of the flue gas in the purification chamber 101 is monitored in real time by the temperature sensor 108. When the flue gas is cooled by the condensation plate 12 and the temperature drops to the set range, the air control valve 107 in the temperature control pipe 106 automatically opens, allowing the treated flue gas to enter the primary drum 6 for subsequent use. If the flue gas temperature is too high, the air control valve 107 remains closed to ensure that the high-temperature flue gas does not enter the primary drum 6 to prevent damage to the equipment.

[0047] A condensation plate 12 located at the air outlet 3 is arranged on the inner wall of the purification chamber 101. The condensation plate 12 is spaced apart from the top of the purification chamber 101, and a flue gas channel 13 is formed therebetween. A cooling device 14 is arranged in the condensation plate 12. The cooling device 14 is used to reduce the temperature of the side of the condensation plate 12 facing the bottom of the purification chamber 101. The cooling device 14 is electrically connected to the temperature sensor 108. The cross-section of one side of the condensation plate 12 away from the air outlet 3 is a conical structure extending toward the bottom of the purification chamber 101. The cooling device 14 is a semiconductor refrigeration plate, and its cooling end is in contact with the cooling surface of the condensation plate 12, and the hot end is connected to a radiator 15 located outside.

[0048] The condensation plate 12 is arranged at the top of the purification chamber 101, at a certain distance from the air outlet 3, and is cooled by a semiconductor refrigeration plate. The cooling surface of the condensation plate 12 faces the bottom of the purification chamber 101. When the flue gas flows through the condensation plate 12, the heat is absorbed by the condensation plate 12, and part of the water vapor and moisture are condensed. The condensed moisture is discharged through the drain port 162 at the bottom of the purification chamber 101 to ensure that the moisture in the purification chamber 101 will not accumulate excessively, thereby ensuring that the humidity of the flue gas entering the raw drum 6 will not be too high. The condensation plate 12 provides a low-temperature surface through the semiconductor refrigeration plate, which can further reduce the flue gas temperature and condense water vapor. The condensed moisture reduces the moisture content in the purification chamber 101, avoiding the impact of moisture accumulation on the emission system. At the same time, the design of the condensation plate 12 can also capture some untreated particulate matter and pollutants, further improving the purification effect and ensuring that the exhaust gas meets environmental protection standards.

[0049] The above technical solution improves the efficiency and effect of flue gas incineration and purification through the innovative design of conical flame gathering design, spiral heat exchange pipe 102, steam nozzle 104, condensation plate 12 and intelligent temperature control system. The design of each structure is closely combined to ensure the realization of efficient incineration, waste heat recovery, cooling purification and temperature control, thereby achieving the comprehensive effect of environmental protection, energy saving and safety.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
