Description

Technical Field

[0001] This utility model belongs to the field of incineration equipment technology, and in particular relates to a combined incineration device for acrylonitrile waste gas and waste liquid. Background Technology

[0002] Acrylonitrile, as an important chemical raw material, generates a large amount of waste gas and waste liquid during its production process. The waste gas produced during acrylonitrile production contains toxic and harmful substances such as acrylonitrile, hydrogen cyanide, and acetonitrile. These substances not only have irritating odors but also harm human health and the environment. If discharged directly without treatment, they will cause air pollution, leading to environmental problems such as acid rain and smog. The waste liquid contains high concentrations of organic pollutants, such as acrylonitrile monomers, polymers, and other impurities. If these waste liquids are discharged directly, they will pollute soil and water bodies, affecting the balance of the ecosystem. With increasing environmental awareness, countries are continuously tightening emission standards for waste gas and waste liquids. The treatment of acrylonitrile waste gas and waste liquids requires that their emission indicators meet national or local standards to reduce environmental impact. Incineration is a commonly used waste gas and waste liquid treatment method. Through high-temperature combustion, waste is converted into harmless substances. Incineration technology has the advantages of high treatment efficiency and thorough treatment, and can effectively remove harmful substances from waste gas and waste liquids.

[0003] However, in the operation of existing acrylonitrile waste gas and waste liquid co-incineration devices, the combustible components in the waste gas are unevenly distributed, resulting in unstable flames and incomplete combustion. This leads to the generation of harmful pollutants such as carbon monoxide and unburned organic matter, and reduces combustion efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an acrylonitrile waste gas and waste liquid co-incineration device. By setting up a stirring mechanism, it solves the problem that in the existing acrylonitrile waste gas and waste liquid co-incineration devices, the combustible components in the waste gas are unevenly distributed during use, resulting in unstable flames and incomplete combustion, which in turn produces harmful pollutants such as carbon monoxide and unburned organic matter, and reduces combustion efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a combined incineration device for acrylonitrile waste gas and waste liquid, including an incineration box, which is equipped with a stirring mechanism and a one-way flow mechanism.

[0007] The stirring mechanism includes a stirring assembly and an inner wall cleaning assembly. The stirring assembly includes a rotating shaft 1 rotatably connected to the inner wall of the right side of the incinerator. The right side of the rotating shaft 1 extends rotatably out of the incinerator. A support plate is fixedly connected to the outer wall of the rotating shaft 1. Several rotating shafts 2 are rotatably connected to the left side of the support plate. Several stirring plates are fixedly connected to the outer walls of the several rotating shafts 2. A motor is fixedly connected to the right side of the incinerator. The output shaft of the motor is fixedly connected to the rotating shaft 1 through a coupling.

[0008] Furthermore, a gear ring is fixedly connected to the inner wall of the incinerator, and gears are fixedly connected to the outer walls of several rotating shafts, with each gear meshing with the gear ring.

[0009] Furthermore, the inner wall cleaning assembly includes several connecting rods fixedly connected to the outer wall of the rotating shaft, several scrapers fixedly connected to the side of the connecting rods away from the rotating shaft, and the side of the scrapers away from the rotating shaft is in contact with the inner wall of the incinerator.

[0010] Furthermore, the unidirectional flow mechanism includes an exhaust pipe connected to the top of the incinerator, and a cross support frame is fixedly connected to the inner wall of the exhaust pipe.

[0011] Furthermore, a matching ring is fixedly connected to the inner wall of the air outlet pipe, and a piston is slidably connected to the inner wall of the matching ring.

[0012] Furthermore, a telescopic rod is fixedly connected to the bottom of the cross support frame, the bottom of the telescopic rod is fixedly connected to the piston, a spring is sleeved on the outer wall of the telescopic rod, the top of the spring is fixedly connected to the cross support frame, and the bottom of the spring is fixedly connected to the piston.

[0013] Furthermore, an exhaust gas inlet is connected to the top of the incinerator, and an atomizing pipe is also connected to the top of the incinerator.

[0014] This utility model has the following beneficial effects:

[0015] 1. By setting up a stirring mechanism, the motor is started simultaneously with incineration. The motor drives the first rotating shaft to rotate. When the first rotating shaft rotates, it drives several second rotating shafts to revolve around the first rotating shaft through the support plate. When the several second rotating shafts revolve simultaneously, due to the setting of the gear ring and gear, the several second rotating shafts will also rotate on their own axis. Thus, the liquid and gas in the incineration chamber are fully stirred by the stirring plate, so that the waste gas can come into full contact with oxygen and the combustible components in the waste liquid can be better dispersed in the air. This creates good conditions for complete combustion, reduces incomplete combustion, improves combustion efficiency, and allows more harmful substances to be decomposed and transformed during combustion. It also makes the heat more evenly distributed in the incineration chamber, avoiding local overheating or overcooling, further improving combustion efficiency and reducing energy waste.

[0016] 2. By setting up a one-way flow mechanism, when waste liquid and waste gas are incinerated in the incinerator, a large amount of carbon dioxide and water are produced. Because of combustion, the internal temperature of the incinerator is high. According to the principle of thermal expansion and contraction and the carbon dioxide and water produced during combustion, the gas pressure inside the incinerator is greater than one standard atmosphere. Therefore, during combustion, the gas pressure inside the incinerator pushes the piston upward, causing it to disengage from the fitting ring and create a gap. The reactants produced by combustion flow out of the device through this gap. During this process, the telescopic rod and spring are compressed as the piston moves upward, and the spring is compressed during this process. During the process, elastic deformation occurs, generating elastic force. When the gas pressure inside the incinerator returns to equilibrium, the piston resets under the spring force and re-engages with the matching ring, restoring the device to a sealed state. This allows for the timely release of excessive pressure, preventing damage to the incinerator caused by continuous pressure increases, such as rupture of the chamber or cracking of welds. This ensures the structural safety of the equipment and prevents serious safety accidents such as explosions caused by excessive pressure. The device can quickly and automatically return to a sealed state after pressure changes without manual intervention, ensuring continuous and stable operation of the device and reducing device malfunctions and process interruptions caused by pressure changes.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5As shown, this utility model is a combined incineration device for acrylonitrile waste gas and waste liquid, including an incineration chamber 1. The incineration chamber 1 is equipped with a stirring mechanism 2 and a one-way flow mechanism 3. The stirring mechanism 2 includes a stirring assembly 21 and an inner wall cleaning assembly 22. The stirring assembly 21 includes a rotating shaft 211 rotatably connected to the inner wall of the right side of the incineration chamber 1. The right side of the rotating shaft 211 extends rotatably to the outside of the incineration chamber 1. A support plate 212 is fixedly connected to the outer wall of the rotating shaft 211. Several rotating shafts 213 are rotatably connected to the left side of the support plate 212. Several stirring plates 214 are fixedly connected to the outer walls of the several rotating shafts 213. A motor 215 is fixedly connected to the right side of the incineration chamber 1. The output shaft of the motor 215 is fixedly connected to the rotating shaft 211 through a coupling. A gear ring 216 is fixedly connected to the inner wall of the incineration chamber 1. The outer walls of the several rotating shafts 213 are... All components are fixedly connected with gears 217, and several gears 217 mesh with gear rings 216. The inner wall cleaning component 22 includes several connecting rods 221 fixedly connected to the outer wall of the rotating shaft 211. Several scrapers 222 are fixedly connected to the side of the connecting rods 221 away from the rotating shaft 211. The side of the scrapers 222 away from the rotating shaft 211 is in contact with the inner wall of the incinerator 1. By setting the stirring mechanism 2, the exhaust gas can be fully contacted with oxygen, and the combustible components in the waste liquid can be better dispersed in the air, thereby creating good conditions for complete combustion, reducing incomplete combustion, improving combustion efficiency, decomposing and transforming more harmful substances during combustion, and distributing heat more evenly in the incinerator 1, avoiding local overheating or overcooling, further improving combustion efficiency and reducing energy waste.

[0028] The one-way flow mechanism 3 includes an exhaust pipe 301 connected to the top of the incinerator 1. A cross support frame 302 is fixedly connected to the inner wall of the exhaust pipe 301. An adapter ring 303 is fixedly connected to the inner wall of the exhaust pipe 301. A piston 304 is slidably connected to the inner wall of the adapter ring 303. A telescopic rod 305 is fixedly connected to the bottom of the cross support frame 302. The bottom of the telescopic rod 305 is fixedly connected to the piston 304. A spring 306 is sleeved on the outer wall of the telescopic rod 305. The top of the spring 306 is fixedly connected to the cross support frame 302, and the bottom of the spring 306 is fixedly connected to the piston 304. The top of the incinerator 1 is connected to an exhaust gas inlet 101 and an atomizing pipe 102. By setting a one-way flow mechanism 3, excessive pressure can be released in time, avoiding damage to the incinerator 1 caused by continuous pressure rise, such as box rupture or weld cracking. This ensures the structural safety of the equipment and prevents serious safety accidents such as explosions caused by excessive pressure. The device can quickly and automatically return to a sealed state after pressure changes without manual intervention, ensuring the continuous and stable operation of the device and reducing device failures and interruptions in the processing caused by pressure changes.

[0029] A specific application of this embodiment is as follows: In use, the device is first placed in the appropriate position. The gas to be incinerated is continuously supplied to the incineration chamber 1 through the exhaust gas inlet 101. The liquid to be incinerated is atomized through the atomizing tube 102 and continuously supplied to the incineration chamber 1. At this time, the incineration chamber 1 is opened to incinerate the liquid and gas within it. Simultaneously, the motor 215 is started, driving the rotating shaft 211 to rotate. While the rotating shaft 211 rotates, it also drives several rotating shafts 213 to revolve around it simultaneously via the support plate 212. During this revolve, due to the gear ring 216 and gear 217, the rotating shafts 213 also rotate on their own axis, thereby fully agitating the liquid and gas within the incineration chamber 1 through the stirring plate 214. This process effectively agitates the waste liquid and gas within the incineration chamber 1. When the waste gas is incinerated, a large amount of carbon dioxide and water are produced. Because of the combustion, the internal temperature of the incinerator 1 is high. Based on the principle of thermal expansion and contraction and the carbon dioxide and water produced during combustion in the incinerator 1, the gas pressure inside the incinerator 1 is greater than one standard atmosphere. Therefore, during combustion in the incinerator 1, the gas pressure inside the incinerator 1 pushes the piston 304 upwards, disengaging it from the adapter ring 303 and creating a gap. The reactants produced during combustion in the incinerator 1 flow out of the device through this gap. During this process, the telescopic rod 305 and the spring 306 are compressed as the piston 304 moves upwards. The spring 306 undergoes elastic deformation and generates elastic force during this compression. When the gas pressure inside the incinerator 1 returns to equilibrium, the piston 304 resets under the elastic force of the spring 306, re-engaging with the adapter ring 303, restoring the device to a sealed state.
