Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment, in particular to waste gas treatment equipment and a treatment process thereof for a reactor used for producing terpineol by a two-step method. Background Art

[0002] As an important fragrance and chemical intermediate, terpineol undergoes a series of complex chemical reactions in the reactor during the two-step production process. However, these reactions inevitably produce waste gas. The waste gas in the production process of terpineol contains a variety of components, such as unreacted raw materials, volatile organic compounds (VOCs), and by-products generated during the reaction process. If these waste gases are directly discharged into the atmosphere, it will not only cause a waste of resources, but also cause serious harm to the environment and human health. For example, VOCs are important precursors to the formation of photochemical smog and ozone pollution. At the same time, some waste gas components may have irritating odors or toxicity, affecting the surrounding air quality and the quality of life of residents.

[0003] In the two-step production of pine alcohol, the waste gas generated in the hydration stage is relatively violent. This characteristic brings many challenges to the waste gas treatment. First, the waste gas flow is unstable and the composition is complex, including pine alcohol and its by-products, volatile organic compounds and other components. This makes it difficult for the traditional air intake method to achieve uniform air intake distribution. The waste gas is easy to concentrate on the local area in the tower, which leads to uneven processing loads in different areas of the packing layer. Some areas may process too much waste gas while other areas are not fully utilized, affecting the overall processing efficiency. Secondly, the intensity of waste gas generation causes unstable air intake speed. Unstable air intake speed will make it difficult to control the residence time of waste gas in the packing layer. When the speed is too fast, the packing and the absorption liquid will not have time to fully react or absorb the harmful substances in the waste gas, so that the waste gas still contains a large amount of pollutants when it is discharged from the equipment, reducing the treatment efficiency; uneven speed will affect the contact effect between the waste gas and the packing and the absorption liquid, resulting in an imbalance in the gas-liquid mass transfer process and increasing the equipment operation cost. In addition, the intensity of waste gas generation in the hydration stage will also cause large fluctuations in the air intake speed and pressure, making it difficult to maintain a stable air intake state. Unstable air intake will destroy the gas-liquid balance in the packing layer, interfere with the gas-liquid mass transfer process, lead to unstable treatment effects, and increase the risk of equipment failure. Summary of the invention

[0004] The object of the present invention is to provide a waste gas treatment device and a treatment process for a reactor for producing terpineol in a two-step process, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions: A waste gas treatment device for a reactor for producing terpineol in a two-step process comprises a waste gas treatment tower, wherein an air intake component is arranged inside the waste gas treatment tower; The air intake component is used to disperse the airflow, and the air intake component includes a uniform component and a buffer component; The uniform component is used to uniformly distribute the airflow, including a dispersion cylindrical cavity, the dispersion cylindrical cavity is located inside the exhaust gas treatment tower, a spiral guide channel is provided inside the dispersion cylindrical cavity, and a connecting pipe is provided on the top of the spiral guide channel; The buffer component is used to buffer the air flow speed, and comprises a gas buffer cavity, a second buffer plate is arranged inside the gas buffer cavity, a third buffer plate is arranged on the top of the second buffer plate, and a first buffer plate is arranged on the top of the third buffer plate.

[0006] By evenly distributing the airflow, it is ensured that the exhaust gas can evenly enter the subsequent treatment links. During the exhaust gas treatment process, the fillers and other treatment components can evenly contact the various components in the exhaust gas, avoiding the situation where the local area is overloaded and other areas are not fully utilized. The buffer component can buffer the airflow velocity. When the exhaust gas flow rate suddenly increases, the gas buffer cavity and the second buffer plate, the third buffer plate and the first buffer plate inside can accommodate excess exhaust gas, avoiding excessive impact of high-speed airflow on subsequent treatment components, and making the exhaust gas contact with the treatment liquid or filler at a suitable speed, ensuring sufficient contact time and good contact state between gas and liquid, thereby improving the mass transfer efficiency.

[0007] A plurality of through holes are provided inside the first buffer plate, the second buffer plate and the third buffer plate, and the diameters of the through holes decrease from bottom to top.

[0008] The connecting pipe is connected with the spiral guide channel, the top of the connecting pipe is connected with the gas buffer chamber, both ends of the gas buffer chamber are provided with support plates, and the opposite ends of the two support plates are connected with the exhaust gas treatment tower.

[0009] Two grid plates are arranged on the top of the gas buffer chamber, filler placing frames are arranged on the tops of the two grid plates, and flow guide rings are arranged on the outer sides of the two filler placing frames.

[0010] The bottom ends of the two guide rings are respectively connected to the tops of the corresponding filler placement frames, and the tops of the two guide rings are connected to the inner wall of the exhaust gas treatment tower. The cross-sections of the two guide rings are triangular, and the inner sides of the two guide rings are inclined.

[0011] The insides of the two filler placing frames are both provided with fillers, and the tops of the two filler placing frames are both provided with placing plates.

[0012] The top of the waste gas treatment tower is provided with a top layer, and the insides of two filler placing frames are provided with breaking components.

[0013] The breaking up component includes a motor, which is located at the top of the top layer. The output end of the motor is fixedly connected to a rotating rod, one end of the rotating rod passes through two filling placement frames, and both ends of the rotating rod are provided with a group of stirring paddles. The number of stirring paddles in each group is set to multiple, and each group of stirring paddles is located inside the corresponding filling placement frame.

[0014] When treating waste gas, some impurities in the waste gas or certain substances in the liquid may be deposited on the surface of the packing or accumulated in the pores of the packing, causing the packing to be blocked. The stirring action of the agitator can prevent this from happening. The motor regularly turns the packing to prevent the accumulation of impurities and substances on the surface and pores of the packing, ensuring that the packing maintains good air permeability and liquid permeability. This allows the gas to pass smoothly through the packing and fully contact the liquid, maintaining an efficient gas-liquid mass transfer process and ensuring that the harmful substances in the waste gas are effectively absorbed or reacted by the liquid, thereby maintaining the efficiency of waste gas treatment.

[0015] Two spray plates are provided inside the exhaust gas treatment tower, and a plurality of nozzles are connected at the bottom of the two spray plates. A base is provided at the bottom of the exhaust gas treatment tower, an air inlet is connected at one end of the exhaust gas treatment tower, an air outlet pipe is provided at the top of the top layer, and a liquid inlet pipe is connected at the top of the two spray plates, and one end of the two liquid inlet pipes extends through to the outside of the exhaust gas treatment tower.

[0016] The present invention also discloses a waste gas treatment process for a reactor for producing terpineol by a two-step method, comprising the following steps: S1: The waste gas generated by terpineol during the hydration stage enters the waste gas treatment tower through the air inlet under pressure or the action of the fan, and the uniform and buffer components in the air intake assembly pre-treat the air flow; S2: External liquid enters two spray plates through the liquid inlet pipe, and is sprayed out by the nozzle after the liquid level is formed in the plate, increasing the gas-liquid contact area to treat the exhaust gas; S3: The exhaust gas flows upward through the packing in the packing placement frame, and the internal breaking component is driven by a motor to drive the stirring paddle to turn the packing to prevent clogging; S4: During the treatment process, the grid plate supports the packing placement frame, and the guide ring corrects the wall flow liquid to ensure the gas-liquid mass transfer effect; S5: The gas after the above treatment is discharged from the waste gas treatment tower through the outlet pipe at the top of the top layer.

[0017] Compared with the prior art, the present invention has the following beneficial effects: The present invention ensures that the waste gas can enter the subsequent treatment links evenly by evenly distributing the airflow. During the waste gas treatment process, the processing components such as the filler can evenly contact the various components in the waste gas, avoiding the situation where the local area is overloaded and other areas are not fully utilized. The buffer component can buffer the airflow velocity. When the waste gas flow rate suddenly increases, the gas buffer cavity and the second buffer plate, the third buffer plate and the first buffer plate inside can accommodate excess waste gas, avoiding excessive impact of the high-speed airflow on the subsequent treatment components, and making the waste gas contact with the treatment liquid or the filler at a suitable speed, ensuring sufficient contact time and a good contact state between the gas and the liquid, thereby improving the mass transfer efficiency.

[0018] The packing placement frame of the present invention is used for placing packing. The structural design of the packing placement frame can stably accommodate the packing therein to prevent the packing from shifting or scattering during the exhaust gas treatment process. When the exhaust gas passes through, the packing comes into contact with the exhaust gas to perform physical or chemical actions to treat harmful substances in the exhaust gas. When the wall flow phenomenon has occurred, the guide ring can correct the flow direction of the wall flow liquid to a certain extent. It can redirect the liquid that has flowed down the tower wall to the packing layer inside the packing placement frame after passing through the placement plate, so that this part of the liquid can re-participate in the gas-liquid mass transfer process, effectively improving the wall flow phenomenon in the exhaust gas treatment tower.

[0019] When the present invention treats waste gas, some impurities in the waste gas or certain substances in the liquid may be deposited on the surface of the filler or accumulated in the pores of the filler, causing clogging of the filler. The stirring action of the stirring paddle can prevent this from happening. The filler is regularly turned over by a motor to prevent the accumulation of impurities and substances on the surface and pores of the filler, ensuring that the filler maintains good air permeability and liquid permeability. This allows the gas to pass smoothly through the filler and fully contact with the liquid, maintaining an efficient gas-liquid mass transfer process, ensuring that the harmful substances in the waste gas are effectively absorbed or reacted by the liquid, thereby maintaining the efficiency of waste gas treatment.

[0022] The following will be combined with the drawings in 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 protection of the present invention.

[0023] like Figure 1-Figure 8 The waste gas treatment equipment of a reactor for producing terpineol by a two-step method shown comprises a waste gas treatment tower 1, wherein an air intake assembly is provided inside the waste gas treatment tower 1; The air intake component is used to disperse the airflow, and the air intake component includes a uniform component and a buffer component; The uniform component is used to uniformly distribute the airflow, including a dispersion cylindrical cavity 7, the dispersion cylindrical cavity 7 is located inside the exhaust gas treatment tower 1, a spiral guide channel 8 is provided inside the dispersion cylindrical cavity 7, and a connecting pipe 9 is provided on the top of the spiral guide channel 8; The buffer component is used to buffer the air flow speed, and includes a gas buffer chamber 10 . A second buffer plate 19 is provided inside the gas buffer chamber 10 . A third buffer plate 20 is provided on the top of the second buffer plate 19 . A first buffer plate 18 is provided on the top of the third buffer plate 20 .

[0024] When the exhaust gas in the hydration stage enters the dispersed cylindrical cavity 7 inside the exhaust gas treatment tower 1, the internal spiral guide channel 8 begins to play a role. The special structure of the spiral guide channel 8 makes the exhaust gas flow along the spiral path. The exhaust gas constantly collides and mixes in this process. Due to the guiding effect of the spiral structure on the airflow, the original concentrated flow direction of the exhaust gas is changed, and the exhaust gas from different parts blends with each other, thereby achieving a preliminary uniform distribution. The exhaust gas homogenized by the spiral guide channel 8 flows out through the connecting pipe 9 at the top. The connecting pipe 9 plays a role of connection and transition, and transports the evenly distributed exhaust gas from the uniform component to the buffer component. After the exhaust gas enters the gas buffer cavity 10, the second buffer plate 19, the third buffer plate 20 and The first buffer plate 18 creates resistance to the airflow. Due to the presence of the second buffer plate 19, the third buffer plate 20 and the first buffer plate 18, the airflow velocity is forced to decrease. Moreover, the second buffer plate 19, the third buffer plate 20 and the first buffer plate 18 are provided with a plurality of through holes, and the aperture decreases from bottom to top. When the exhaust gas passes through the second buffer plate 19, the third buffer plate 20 and the first buffer plate 18, the large aperture portion first allows more exhaust gas to pass through. As the exhaust gas flows upward, the aperture becomes smaller, and the flow rate of the exhaust gas is gradually adjusted more finely. This structural design allows the airflow velocity to gradually stabilize when passing through the second buffer plate 19, the third buffer plate 20 and the first buffer plate 18, and also further evens out the distribution of the airflow.

[0025] By evenly distributing the airflow, it is ensured that the exhaust gas can enter the subsequent treatment links evenly. During the exhaust gas treatment process, the filler and other treatment components can evenly contact the various components in the exhaust gas, avoiding the situation where the local area is overloaded and other areas are not fully utilized.

[0026] For example, when absorbing and treating harmful substances in exhaust gas, if the air intake is uneven, it may cause the absorbent in some packing areas to be exhausted prematurely, while the absorbent in other areas does not fully function. Uniform air intake can make full use of the absorption capacity of the entire packing layer, thereby improving the overall exhaust gas treatment efficiency.

[0027] In the process of producing pinene alcohol by the two-step method, the operating state of the reactor may change, resulting in fluctuations in the speed and pressure of waste gas generation. The buffer component can buffer the gas flow rate. When the waste gas flow rate suddenly increases, the gas buffer chamber 10 and the second buffer plate 19, the third buffer plate 20 and the first buffer plate 18 inside can accommodate excess waste gas to prevent the high-speed gas flow from causing excessive impact on subsequent processing components (such as packing layers, etc.); when the waste gas flow rate decreases, the gas buffer chamber 10 and the second buffer plate 19, the third buffer plate 20 and the first buffer plate 18 can replenish the gas flow to maintain a relatively stable intake state (the gas buffer chamber 10 has a certain spatial volume. When the waste gas flow rate is large, part of the waste gas will remain in the buffer chamber, making the buffer chamber like a "waste gas storage reservoir". When the waste gas flow rate decreases, the waste gas stored in the gas buffer chamber 10 will be released under the action of the pressure difference and replenished into the intake gas flow.), the buffer component buffers the gas flow rate so that the waste gas contacts the treatment liquid or filler at a suitable speed, ensuring sufficient contact time and good contact state between the gas and the liquid, thereby improving the mass transfer efficiency.

[0028] like Figure 3-Figure 6 As shown, a plurality of through holes are provided inside the first buffer plate 18, the second buffer plate 19 and the third buffer plate 20, and the apertures of the through holes decrease from bottom to top. The connecting pipe 9 is connected with the spiral guide channel 8, and the top of the connecting pipe 9 is connected with the gas buffer chamber 10. Support plates 11 are provided at both ends of the gas buffer chamber 10, and the opposite ends of the two support plates 11 are connected to the exhaust gas treatment tower 1.

[0029] When the exhaust gas flows from bottom to top through the second buffer plate 19, the third buffer plate 20 and the first buffer plate 18, since the aperture of the through hole decreases from bottom to top, when the exhaust gas is in the lower layer, the larger through hole allows more exhaust gas to pass through. As the exhaust gas flows upward, the aperture of the through hole becomes smaller, which limits the amount of exhaust gas passing through. This structure gradually reduces the amount of exhaust gas passing through according to the direction of exhaust gas flow, thereby adjusting the flow rate of exhaust gas. When the exhaust gas passes through the gradually smaller through holes, the flow rate will increase and the pressure will decrease, which helps to form a stable pressure gradient in the gas buffer chamber 10, so that when the exhaust gas passes through the second buffer plate 19, the third buffer plate 20 and the first buffer plate 18, the pressure gradually changes, avoiding sudden changes in pressure.

[0030] like Figure 7-Figure 8As shown, two grid plates 12 are provided at the top of the gas buffer chamber 10, and a filler placement frame 15 is provided at the top of the two grid plates 12. Guide rings 16 are provided on the outer sides of the two filler placement frames 15. The bottom ends of the two guide rings 16 are respectively connected to the tops of the corresponding filler placement frames 15, and the tops of the two guide rings 16 are connected to the inner wall of the exhaust gas treatment tower 1. The cross-sections of the two guide rings 16 are both triangular, and the inner sides of the two guide rings 16 are inclined. Fillers are provided inside the two filler placement frames 15, and placement plates 17 are provided on the tops of the two filler placement frames 15.

[0031] The grid plate 12 is located at the top of the gas buffer chamber 10, and its main function is to provide support for the filler placement frame 15 above. The grid plate 12 has a certain structural strength and can bear the weight of the filler placement frame 15 and the filler inside it. At the same time, the grid structure of the grid plate 12 can make the exhaust gas coming out of the gas buffer chamber 10 evenly dispersed to the area above it, avoiding the exhaust gas from concentrating on a local area of ​​the filler placement frame 15.

[0032] The filler placement frame 15 is used to place the filler. The structural design of the filler placement frame 15 can stably accommodate the filler therein to prevent the filler from shifting or scattering during the exhaust gas treatment process. When the exhaust gas passes through, the filler comes into contact with the exhaust gas and performs physical or chemical reactions to treat harmful substances in the exhaust gas.

[0033] When wall flow has occurred, the guide ring 16 can correct the flow direction of the wall flow liquid to a certain extent. It can redirect the liquid that has flowed down the tower wall to the packing layer inside the packing placement frame 15 after passing through the placement plate 17, so that this part of the liquid can re-participate in the gas-liquid mass transfer process, effectively improving the wall flow phenomenon in the exhaust gas treatment tower 1.

[0034] like Figure 7-Figure 8 As shown, a top layer 4 is provided on the top of the waste gas treatment tower 1, and a breaking assembly is provided inside the two packing placement frames 15. The breaking assembly includes a motor 14. The motor 14 is located on the top of the top layer 4. The output end of the motor 14 is fixedly connected with a rotating rod 22. One end of the rotating rod 22 passes through the two packing placement frames 15. A group of stirring paddles 23 are provided at both ends of the rotating rod 22. The number of each group of stirring paddles 23 is set to multiple, and each group of stirring paddles 23 is respectively located inside the corresponding packing placement frame 15.

[0035] The motor 14 is located at the top of the top layer 4 as a power source. When the motor 14 is started, its output end begins to rotate. The output end of the motor 14 is fixedly connected to the rotating rod 22. The rotational motion of the motor 14 is directly transmitted to the rotating rod 22, so that the rotating rod 22 rotates around its axis. A group of stirring paddles 23 are provided at both ends of the rotating rod 22, and each group of stirring paddles 23 is respectively located inside the corresponding filler placement frame 15. When the rotating rod 22 rotates, the stirring paddles 23 make circular motion with the rotating rod 22. When the stirring paddles 23 move in the filler in the filler placement frame 15, they stir the filler.

[0036] During the waste gas treatment process, some impurities in the waste gas or certain substances in the liquid may be deposited on the surface of the packing or accumulated in the pores of the packing, causing the packing to be blocked. The stirring action of the stirring paddle 23 can prevent this from happening. The motor 14 regularly turns the packing to prevent the accumulation of impurities and substances on the surface and pores of the packing, ensuring that the packing maintains good air permeability and liquid permeability, so that the gas can smoothly pass through the packing and fully contact the liquid, maintaining an efficient gas-liquid mass transfer process, ensuring that the harmful substances in the waste gas are effectively absorbed or reacted by the liquid, thereby maintaining the efficiency of waste gas treatment.

[0037] like Figure 1-Figure 3 As shown, two spray plates 13 are provided inside the exhaust gas treatment tower 1, and the bottoms of the two spray plates 13 are connected to multiple nozzles 21, a base 3 is provided at the bottom of the exhaust gas treatment tower 1, an air inlet 2 is provided at one end of the exhaust gas treatment tower 1, an air outlet pipe 6 is provided at the top of the top layer 4, and the tops of the two spray plates 13 are connected to liquid inlet pipes 5, and one ends of the two liquid inlet pipes 5 extend through to the outside of the exhaust gas treatment tower 1.

[0038] The air inlet 2 is connected to the external exhaust gas source, and the exhaust gas enters the tower under the pressure of the exhaust gas source or the action of the fan. The liquid is input through the liquid inlet pipe 5 at the top of the two spray plates 13. After the liquid forms a liquid level in the spray plate 13, it is sprayed into small droplets through multiple nozzles 21 at the bottom. This process not only increases the contact area between the liquid and the exhaust gas, which is beneficial for the harmful substances in the exhaust gas to contact with the spray liquid and be absorbed or chemically react to improve the treatment effect, but also because the layered setting of the two spray plates 13 realizes the layered treatment of the exhaust gas to ensure uniformity. In the tower, the gas goes up and the liquid goes down. The filler in the filler placement frame 15 can assist in the treatment of the exhaust gas, and the internal scattering component can prevent the filler from being blocked to maintain the treatment efficiency. After treatment, the gas is discharged through the outlet pipe 6 at the top of the top layer 4.

[0039] like Figure 1-Figure 8 As shown, the present invention also discloses a waste gas treatment process for a reactor for producing terpineol by a two-step method, comprising the following steps: S1: The waste gas generated during the hydration stage of terpineol enters the waste gas treatment tower 1 through the air inlet 2 under pressure or the action of a fan, and the uniform and buffer components in the air intake assembly pre-treat the air flow; S2: External liquid enters two spray plates 13 through the liquid inlet pipe 5, and is sprayed out by the nozzle 21 after forming a liquid level in the plate, thereby increasing the gas-liquid contact area to treat the waste gas; S3: the exhaust gas flows upward through the packing in the packing placement frame 15, and the internal breaking assembly is driven by the motor 14 to drive the stirring paddle 23 to turn the packing to prevent clogging; S4: During the treatment process, the grid plate 12 supports the filler placement frame 15, and the guide ring 16 corrects the wall flow liquid to ensure the gas-liquid mass transfer effect; S5: The gas that has undergone the above treatment is discharged from the waste gas treatment tower 1 through the gas outlet pipe 6 at the top of the top layer 4.

[0040] Working principle: The waste gas enters the waste gas treatment tower 1 through the air inlet 2 under the pressure of the reactor itself or the action of the fan. The uniform component in the air inlet assembly is operated first, and the waste gas enters the spiral guide channel 8 in the dispersed cylindrical cavity 7. The special spiral structure of the spiral guide channel 8 prompts the waste gas to flow along the spiral path, during which the waste gas molecules collide and mix with each other to achieve preliminary uniform distribution. After that, the waste gas enters the gas buffer cavity 10 of the buffer component through the connecting pipe 9.

[0041] The second buffer plate 19, the third buffer plate 20 and the first buffer plate 18 in the gas buffer chamber 10 have an important influence on the airflow. The apertures of the internal through holes of these buffer plates decrease from bottom to top. When the exhaust gas flows from bottom to top, the larger through holes in the lower layer first allow more exhaust gas to pass through. When flowing upward, the through holes become smaller, limiting the amount of exhaust gas passing through. This design can adjust the flow rate, stabilize the flow rate, and further evenly distribute the airflow. This mechanism can well adapt to the fluctuations in the speed and pressure of exhaust gas generation when the reactor is running, ensuring that the exhaust gas contacts the subsequent treatment components in a suitable state.

[0042] Then, the gas reaches the grid plate 12 at the top of the gas buffer chamber 10. The grid plate 12 has sufficient structural strength to support the upper filler placement frame 15. At the same time, its grid structure evenly disperses the exhaust gas. The filler in the filler placement frame 15 contacts the exhaust gas to treat the harmful substances in it. The guide ring 16 on the outside can correct the wall flow liquid to prevent the liquid from flowing along the tower wall and affecting the treatment effect.

[0043] At the same time, the two spray plates 13 are introduced with liquid through the liquid inlet pipe 5. After the liquid forms a liquid level in the spray plate 13, it is sprayed into small droplets through multiple nozzles 21 at the bottom. These small droplets flow in the opposite direction of the exhaust gas, and the stratified treatment increases the gas-liquid contact area, which is conducive to the absorption or reaction of harmful substances in the exhaust gas.

[0044] During the processing, the breaking up component in the filler placement frame 15 starts to work, the motor 14 drives the rotating rod 22 to rotate, and the rotating rod 22 drives the stirring paddles 23 at both ends to turn the filler, which can prevent impurities from accumulating on the surface and pores of the filler and causing blockage, maintain the air permeability and liquid permeability of the filler, and ensure the gas-liquid mass transfer efficiency.

[0045] Finally, the gas that has undergone a series of treatments is discharged from the exhaust gas treatment tower 1 through the outlet pipe 6 at the top of the top layer 4, while the base 3 at the bottom of the tower provides support for the entire device to ensure stable operation of the device.

[0046] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
