Description

Technical Field

[0001] The present invention relates to the technical field of purifying agent preparation, and specifically to a flue gas purifying agent and its preparation equipment. Background Art

[0002] A flue gas purifying agent is a chemical agent used to reduce, treat or eliminate flue gas pollution. The flue gas purifying agent contains alkylphenol polyoxyethylene ether, sodium carbonate, anhydrous sodium sulfate and a denitration agent. Among them, in the denitration flue gas purifying agent, the effective component content of the denitration agent is as high as 99%. The main use of the flue gas purifying agent is to treat the flue gas generated in industrial and urban waste treatment sites to reduce its harm to the environment and human body.

[0003] However, the following problems still exist in the specific preparation process of the denitration agent:

[0004] 1. In the preparation process of the existing denitration agent, due to the high viscosity of some raw materials of the denitration agent, it will cause the raw materials to adhere more easily to the inner wall of the stirring barrel during the stirring process; and the raw materials with high viscosity have greater resistance when flowing and are not easily mixed with the eddy current formed by the stirrer, resulting in adhesion to the inner wall of the stirring barrel. The mixed solvent adhering to the inner wall of the stirring barrel cannot fully participate in the denitration reaction. Because the effective components in this part of the solvent are not fully utilized, the efficiency of the entire denitration process will be affected, resulting in a reduction in the denitration efficiency of the denitration agent.

[0005] 2. In addition, during the stirring process, since a certain temperature will be generated during the stirring process, and too high a temperature will cause the raw materials to expand and generate bubbles when mixed. The generation of bubbles will interfere with the uniform mixing of the raw materials, making the stirring effect greatly reduced. This will lead to uneven distribution of the effective components in the denitration agent, and further affect its denitration performance.

[0006] Therefore, a flue gas purifying agent and its preparation equipment are proposed to solve the above problems. Summary of the Invention

[0007] In view of this, the technical problem to be solved by the present invention is to propose a flue gas purifying agent and its preparation equipment to solve the problems of easy adhesion to the inner wall during the mixing of the denitration agent preparation in the prior art, resulting in insufficient stirring and generation of bubbles.

[0008] To achieve the above object, the present invention provides the following technical solution: A flue gas purifying agent and its preparation equipment, the common components of the purifying agent include alkylphenol polyoxyethylene ether, sodium carbonate, anhydrous sodium sulfate, and a denitration agent.

It is characterized in that it further includes an adjustable air pressure stirring mechanism and a multi-functional stirring and mixing mechanism, and the adjustable air pressure stirring mechanism and the multi-functional stirring and mixing mechanism are respectively arranged in the middle and inner wall of the mixing chamber;

[0020] The adjustable air pressure stirring mechanism is used for pressure adjustment during the stirring process of the denitrification agent raw materials;

[0021] The multi-functional stirring and mixing mechanism is used to prevent adhesion to the inner wall of the mixing chamber.

[0022] Preferably, the adjustable air pressure stirring mechanism includes a driving block. A motor is installed on the upper surface of the mixing chamber. The middle of the driving block is fixedly connected to the driving shaft of the motor. An arc-shaped inclined groove is formed on the outer surface of the driving block. An extrusion block is slidably connected in the arc-shaped inclined groove. The bottom of the extrusion block is fixedly connected to the air pushing disk.

[0023] Preferably, the adjustable air pressure stirring mechanism further includes a rotating threaded block. The rotating threaded block is threadedly connected to an exhaust threaded cylinder. The bottom of the exhaust threaded cylinder is height-connected to the upper surface of the air pushing disk. A tension spring is fixedly connected to the bottom of the rotating threaded block. One end of the tension spring away from the rotating threaded block is fixedly connected to a threaded column, and the threaded column is threadedly connected to a threaded fixing block.

[0024] Preferably, exhaust holes are symmetrically formed in the air pushing disk. The outer surface of the threaded fixing block is slidably connected in the exhaust holes formed in the air pushing disk. A sealing block is fixedly connected to one end of the threaded fixing block away from the tension spring.

[0025] Preferably, the multi-functional stirring and mixing mechanism includes a connecting shaft. The upper end of the connecting shaft is fixedly connected to the driving shaft of the motor at the upper end of the mixing chamber. Stirring rods are symmetrically and fixedly connected to the outer surfaces of both ends of the connecting shaft. An arc-shaped cleaning scraper is fixedly connected to one end of the stirring rod away from the connecting shaft. Stirring blades are fixedly connected to the outer surface of the connecting shaft. A cleaning pushing plate is fixedly connected to the bottom of the connecting shaft. The cleaning pushing plate is slidably connected to the bottom of the mixing chamber.

[0026] Preferably, a defoaming and cleaning multi-functional mechanism is further provided at the bottom of the mixing chamber. The defoaming and cleaning multi-functional mechanism includes a filter screen. A discharge port is formed at the bottom of the mixing chamber. The filter screen is fixedly connected to the upper surface of the discharge port at the bottom of the mixing chamber. A sealing disk is provided at the bottom of the filter screen.

[0027] Preferably, a seesaw is fixedly connected to the lower surface of the middle of the sealing disk. A connecting block is rotatably connected to the middle of the seesaw. One end of the connecting block away from the seesaw is fixedly connected to the mixing chamber. An electric telescopic rod is rotatably connected to one end of the seesaw away from the sealing disk. The electric telescopic rod is installed on the mixing chamber.

[0028] Compared with the prior art, a flue gas purifying agent and its preparation equipment provided by the present invention have the following

[0029] Beneficial effects:

[0030] 1. In the present invention, an arc-shaped inclined groove is provided in the driving block. When the driving block rotates, the extrusion of the extrusion block by the arc-shaped inclined groove drives the air-pushing disk to reciprocally push on the inner wall of the mixing chamber. Through the design of the present invention, not only is the stirring more uniform, but also through the continuous pushing of the air-pushing disk, the stirring pressure on the mixture in the mixing chamber below the air-pushing disk can be continuously changed. This change in pressure not only helps the mixture to be fully mixed, but more importantly, it can quickly discharge the heat generated by the mixture during the stirring process through the exhaust holes on the air-pushing disk, thus effectively preventing the problem of excessive stirring temperature inside the mixing chamber, not only improving the stirring efficiency, but also ensuring the safety and stability of the stirring process.

[0031] 2. During the stirring process, bubbles often hinder the mixing and dispersion of materials. In the present invention, the air-pushing disk slides on the inner wall of the mixing chamber to change the pressure inside the stirring barrel, which can not only accelerate the movement and discharge of bubbles, thus avoiding the negative impact of bubbles on the stirring effect, but also the distribution and movement state of bubbles in the stirring barrel will be affected by the pressure, and the change in pressure helps to form a more uniform fluid flow, further improving the stirring effect and the uniformity of material mixing.

[0032] In the present invention, by setting a rotatable threaded block and an exhaust threaded barrel that can be adjusted and replaced by threads, the operator only needs to simply rotate the rotatable threaded block to easily drive the stretching spring thread to disengage from the threaded fixing block, achieving quick replacement. This convenient operation method greatly saves the time for replacement and adjustment, improving work efficiency. Secondly, by replacing stretching springs with different elastic ratios or changing the threaded positions of the rotatable threaded block and the exhaust threaded barrel, the operator can flexibly adjust the elastic strength of the stretching spring. This adjustability enables the present invention to adapt to different stirring requirements and material characteristics, thereby optimizing the stirring effect. More importantly, the change in the elastic strength of the stretching spring can directly affect the pressure generated when the air-pushing disk slides on the inner wall of the mixing chamber. By precisely adjusting the pressure, we can better control the hydrodynamic environment during the stirring process and improve the uniformity and stability of the mixture.

[0033] 3. With the setting of the arc-shaped cleaning scraper and the cleaning push plate, when the arc-shaped cleaning scraper rotates on the connecting shaft, it can quickly drive the arc-shaped cleaning scraper to stir on the inner wall of the mixing chamber. In the present invention, the arc-shaped cleaning scraper is composed of double arc angle plates for scraping the inner wall of the mixing chamber. The bottom arc surface of the cleaning push plate fits the inner wall of the bottom arc surface of the mixing chamber. Different from directly using a vertical scraper in the traditional way, it will cause different stirring parts and reduce the vertical stirring power. Through the setting of the present invention, when the arc-shaped cleaning scraper rotates, it can not only drive the material to be pushed downward along the arc-shaped cleaning scraper, but also quickly scrape off the mixture adhering to the inner wall of the mixing chamber by the arc-shaped cleaning scraper.

[0034] 4. With the filter screen provided in the present invention, when the mixture is discharged, not only can the excess bubbles in the denitration agent be filtered and removed to ensure the quality and performance of the denitration agent, but also when the operator starts the motor to rotate, through the water inlet above the mixing chamber, when the air push plate slides in the mixing chamber, it rotates synchronously through the connecting shaft. At this time, the cleaning liquid above the mixing chamber can be sprayed into the mixing chamber through the exhaust holes to clean the inside of the mixing chamber, and at the same time, the inside of the mixing chamber can be quickly cleaned by the automatic opening of the sealing plate at the discharge port.

[0035] Compared with the traditional cleaning device, with the setting of the present invention, when the mixture is discharged, the device of the present invention can not only effectively filter bubbles, but also ensure the cleanliness of the mixing barrel through precise cleaning procedures. The automated operation design effectively improves work efficiency and safety, and at the same time brings a more convenient and efficient mixing and cleaning experience to users.

[0050] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0051] The following further describes the present invention in detail according to the drawings and embodiments.

[0052] Embodiment 1

[0053] To solve the problems mentioned in the technical solutions, the embodiments of the present application provide a flue gas purifying agent and its preparation equipment. To achieve the above objectives, the present invention provides the following technical solutions: A flue gas purifying agent and its preparation equipment, the common components of the purifying agent include alkylphenol polyoxyethylene ether, sodium carbonate, anhydrous sodium sulfate, and denitration agent. The raw materials for preparing the denitration agent include a carrier, a nitrogen oxide absorbent, an emulsifier, a dispersant, a denitration reaction agent, a catalyst, etc.;

[0054] Order of raw material addition:

[0055] First, some basic raw materials, such as a carrier or a solvent, will be added first to provide a stable reaction environment;

[0056] Second, the nitrogen oxide absorbent, emulsifier, dispersant, denitration reaction agent, and catalyst, etc. will be added sequentially as needed; such an addition order helps to ensure that each raw material can be fully dissolved, dispersed, or reacted, thereby improving the overall performance and stability of the denitration agent;

[0057] Proportion of raw material input:

[0058] Carrier: The carrier serves as the basis for supporting and dispersing other active ingredients. When the flue gas concentration is high and the denitrification efficiency is high, the proportion of the carrier is 40%. By increasing the surface area of the denitrification agent, the carrier improves the contact efficiency with the flue gas, enabling more NOx to be absorbed and converted.

[0059] Nitrogen oxide absorbent: The nitrogen oxide absorbent is used to absorb and convert NOx in the flue gas. When the flue gas concentration is high and the denitrification efficiency is high, the exhaust screw cylinder of the nitrogen oxide absorbent is 25%, which can effectively absorb and convert NOx in the flue gas, significantly reducing its emission concentration, thus meeting the requirements of environmental protection regulations.

[0060] Emulsifier: The emulsifier is used to improve the dispersibility and stability of the denitrification agent in water or other solvents. When the flue gas nitrate concentration is high and the denitrification efficiency is high, its dosage proportion is 4%. It can improve the dispersibility of the denitrification agent in water or other solvents, making it more uniform and stable.

[0061] Dispersant: Similar to the emulsifier, the dispersant is also used to improve the dispersibility and uniformity of each component in the denitrification agent. Its dosage proportion is also relatively low, at 4%. It can prevent the active ingredients from agglomerating or precipitating, ensuring that the denitrification agent always maintains high efficiency during use.

[0062] Denitrification reactant: The denitrification reactant is a key component in the denitrification process, used to chemically react with NOx to convert it into harmless substances. Its dosage proportion is 10%. It can optimize the conversion rate and selectivity of the denitrification agent, reduce the generation of by-products, and improve the denitrification efficiency.

[0063] Catalyst: The catalyst is used to accelerate the denitrification reaction process, improve the reaction rate and efficiency. Its dosage proportion is relatively low, and the proportion of the catalyst may be 5%. By using an efficient catalyst, the use temperature and pressure of the denitrification agent can be reduced, saving energy and costs.

[0064] Example Two

[0065] Please refer to Figures 1 to 9 as shown:

[0066] The flue gas purifying agent preparation equipment includes a preparation device for the denitrification agent, including an operating table 1. A mixing bin 11 is installed on the operating table 1. A gas push plate 12 is slidably connected to the inner wall of the mixing bin 11. It is characterized in that it further includes an adjustable air pressure stirring mechanism 2 and a multi-functional stirring and mixing mechanism 3. The adjustable air pressure stirring mechanism 2 and the multi-functional stirring and mixing mechanism 3 are respectively arranged in the middle and on the inner wall of the mixing bin 11.

[0067] The adjustable air pressure stirring mechanism 2 is used for pressure adjustment during the stirring process of the denitrification agent raw materials.

[0068] The multi-functional stirring and mixing mechanism 3 is used to prevent adhesion to the inner wall of the mixing bin 11.

[0069] The adjustable air pressure stirring mechanism 2 includes a driving block 21. A motor is installed on the upper surface of the mixing chamber 11. The middle part of the driving block 21 is fixedly connected to the driving shaft of the motor. An arc-shaped inclined groove 22 is formed on the outer surface of the driving block 21. An extrusion block 23 is slidably connected in the arc-shaped inclined groove 22. The bottom of the extrusion block 23 is fixedly connected to the air pushing disc 12.

[0070] The adjustable air pressure stirring mechanism 2 further includes a rotating threaded block 24. The rotating threaded block 24 is threadedly connected to an exhaust threaded cylinder 25. The bottom of the exhaust threaded cylinder 25 is height-connected to the upper surface of the air pushing disc 12. A tension spring 26 is fixedly connected to the bottom of the rotating threaded block 24.

The outer surface of the threaded fixing block 27 is slidably connected in the exhaust holes formed in the air pushing disc 12.

[0072] Among them: The rotating threaded block 24 to the sealing block 28 are symmetrically arranged on the exhaust holes of the air pushing disc 12.

[0073] Compared with the prior art, through the implementation of this embodiment, the operator can flexibly adjust the elastic strength of the tension spring 26. This adjustability enables the present invention to adapt to different stirring requirements and material characteristics, thereby optimizing the stirring effect, and thus can better control the hydrodynamic environment during stirring, improving the uniformity and stability of the mixture.

[0074] For further embodiments, please refer to Figures 1 to 9 as shown:

[0075] The multifunctional stirring and mixing mechanism 3 includes a connecting shaft 31. The upper end of the connecting shaft 31 is fixedly connected to the driving shaft of the motor at the upper end of the mixing chamber 11. Stirring rods 32 are symmetrically and fixedly connected to the outer surfaces at both ends of the connecting shaft 31. An arc-shaped cleaning scraper 33 is fixedly connected to one end of the stirring rod 32 away from the connecting shaft 31. A stirring blade 35 is fixedly connected to the outer surface of the connecting shaft 31. A cleaning pushing plate 34 is fixedly connected to the bottom of the connecting shaft 31. The cleaning pushing plate 34 is slidably connected to the bottom of the mixing chamber 11.

[0076] A defoaming and cleaning multifunctional mechanism 4 is further provided at the bottom of the mixing chamber 11. The defoaming and cleaning multifunctional mechanism 4 includes a filter screen 41. A discharge port is formed at the bottom of the mixing chamber 11. The filter screen 41 is fixedly connected to the upper surface of the discharge port at the bottom of the mixing chamber 11. A sealing disc 42 is provided at the bottom of the filter screen 41.

[0077] A seesaw 43 is fixedly connected to the lower surface of the middle part of the sealing disc 42. A connecting block 44 is rotatably connected to the middle part of the seesaw 43. One end of the connecting block 44 away from the seesaw 43 is fixedly connected to the mixing bin 11. An electric telescopic rod 45 is rotatably connected to the end of the seesaw 43 away from the sealing disc 42. The electric telescopic rod 45 is installed on the mixing bin 11.

[0078] Among them: the arc-shaped cleaning scraper 33 is composed of double arc angle plates and is used for scraping the inner wall of the mixing bin 11. The bottom arc surface of the cleaning and pushing plate 34 fits the inner wall of the bottom arc surface of the mixing bin 11.

[0079] Compared with the prior art, by implementing this embodiment, not only can air bubbles be effectively filtered, but also the cleanliness of the mixing barrel can be ensured through a precise cleaning process. The automated operation design effectively improves work efficiency and safety, and at the same time brings a more convenient and efficient mixing and cleaning experience to users.

[0080] The working principle of all the contents in the above-mentioned embodiment is as follows:

[0081] In the initial state: the motor installed on the mixing bin 11 is not started, the electric telescopic rod 45 installed on the outer surface of the mixing bin 11 is not started, the sealing disc 42 is closed at the discharge port at the bottom of the mixing bin 11, and the tension spring 26 is not stretched.

[0082] The following is the working process of the adjustable air pressure stirring mechanism 2 and the multi-functional stirring and mixing mechanism 3 for mixing raw materials:

[0083] The relationship between pressure and volume: Under the condition that the temperature remains unchanged, there is a close relationship between pressure and volume. Specifically, when the volume decreases, the pressure increases; conversely, when the volume increases, the pressure decreases. This relationship can be described by Boyle - Mariotte's law, which states that: at a constant temperature, the pressure (P) of a substance is inversely proportional to the volume (V), that is, PV = C (C is a constant). This means that if we keep the temperature constant, changing the volume will correspondingly change the pressure.

[0084] First, when preparing the denitration agent, basic raw materials such as carriers or solvents are put into the mixing bin 11 through the feeding port of the mixing bin 11.

[0085] Furthermore, according to the need, nitrogen oxide absorbents, emulsifiers, dispersants, denitration reaction agents, catalysts, etc. are added in sequence; such an addition sequence helps to ensure that each raw material can be fully dissolved, dispersed or reacted, thereby improving the overall performance and stability of the denitration agent.

[0086] At this time, after adding each reaction raw material, start the motor installed on the mixing bin 11. Since the motor drive shaft is fixed to the drive block 21 and the connecting shaft 31, when the drive block 21 rotates synchronously at this time, through the extrusion action of the arc-shaped inclined groove 22 on the extrusion block 23, it drives the air push plate 12 to reciprocally push on the inner wall of the mixing bin 11. Through the design of the present invention, not only the stirring is made more uniform, but also through the continuous pushing of the air push plate 12, the stirring pressure on the mixture in the mixing bin 11 below the air push plate 12 can be continuously changed. And this change in pressure not only helps the mixture to be fully mixed, but more importantly, it can quickly discharge the heat generated by the mixture during the stirring process through the exhaust holes on the air push plate 12, thus effectively preventing the problem of excessive stirring temperature inside the mixing bin 11, not only improving the stirring efficiency, but also ensuring the safety and stability of the stirring process.

[0087] At this time, when the air push plate 12 slides in the mixing bin 11, when the mixing bin 11 slides upward, the suction force generated by the pressure below the air push plate 12 will adsorb the Figure 6 shown sealing block 28 to slide downward. At this time, the sealing block 28 will drive the threaded fixing block 27 to stretch the tension spring 26. At this time, the gas below the air push plate 12 will flow out along the exhaust holes on the air push plate 12. During the stirring process, bubbles often hinder the mixing and dispersion of the materials. Through the sliding of the air push plate 12 on the inner wall of the mixing bin 11, the present invention changes the pressure inside the stirring barrel, which can not only accelerate the movement and discharge of the bubbles, thus avoiding the negative impact of the bubbles on the stirring effect, but also the distribution and movement state of the bubbles in the stirring barrel will be affected by the pressure, and the change in pressure helps to form a more uniform fluid flow, further improving the stirring effect and the uniformity of the material mixing.

[0088] Furthermore, when it is necessary to adjust the pressure of the air push plate 12 in the mixing bin 11, the operator only needs to simply rotate the rotating threaded block 24 to easily drive the threaded tension spring 26 to disengage from the threaded fixing block 27, achieving quick replacement. This convenient operation method greatly saves the time for replacement and adjustment, improving the work efficiency. Secondly, by replacing the tension springs 26 with different elastic ratios, or changing the threaded position of the rotating threaded block 24 and the exhaust threaded barrel 25, the operator can flexibly adjust the elastic strength of the tension spring 26. This adjustability enables the present invention to adapt to different stirring requirements and material characteristics, thereby optimizing the stirring effect. More importantly, the change in the elastic strength of the tension spring 26 can directly affect the pressure generated when the air push plate 12 slides on the inner wall of the mixing bin 11. By precisely adjusting the pressure, we can better control the hydrodynamic environment during the stirring process, improving the uniformity and stability of the mixture.

[0089] Further, when the connecting shaft 31 rotates synchronously, it will drive the arc-shaped cleaning scraper 33 and the cleaning and pushing plate 34 to rotate synchronously. With the settings of the arc-shaped cleaning scraper 33, the stirring rod 32, and the cleaning and pushing plate 34, when the arc-shaped cleaning scraper 33 rotates under the drive of the connecting shaft 31, it can quickly drive the arc-shaped cleaning scraper 33 to stir on the inner wall of the mixing bin 11. In the present invention, the arc-shaped cleaning scraper 33 is composed of double arc angle plates for scraping the inner wall of the mixing bin 11. The bottom arc surface of the cleaning and pushing plate 34 fits the inner wall of the bottom arc surface of the mixing bin 11. Different from the traditional direct use of vertical scrapers, it will cause uneven stirring and reduce the vertical stirring power. With the present invention, when the arc-shaped cleaning scraper 33 rotates, it can not only drive the material to be pushed downward along the arc-shaped cleaning scraper 33, but also quickly scrape off the mixture adhering to the inner wall of the mixing bin 11 by the arc-shaped cleaning scraper 33.

[0090] Please refer to the above working process Figures 1 to 9 。

[0091] The following is the working process of the automatic opening of the cleaning and filtering of the degassing cleaning multi-functional mechanism 4:

[0092] At the end of the mixing, at this time, the electric telescopic rod 45 installed on the outer surface of the mixing bin 11 is started. At this time, since the drive shaft of the electric telescopic rod 45 is rotationally connected to one end of the seesaw 43, and at the same time, because the middle of the seesaw 43 is rotationally connected to the connecting block 44, and the connecting block 44 is fixedly connected to the mixing bin 11, so the contraction of the electric telescopic rod 45 at this time will drive the seesaw 43 to start rotating clockwise on the connecting block 44. At this time, the sealing disc 42 fixedly connected to the seesaw 43 starts to open and close from the bottom discharge port of the mixing bin 11. At this time, the mixture in the mixing bin 11 starts to flow into the operating table 1 through the filter screen 41 for collection. With the setting of the filter screen 41 in the present invention, when the mixture is discharged, it can not only filter and remove the excess bubbles in the denitration agent to ensure the quality and performance of the denitration agent, but also when the operator starts the motor to rotate, through the water inlet above the mixing bin 11, when the air pushing disc 12 slides in the mixing bin 11, it rotates synchronously through the connecting shaft 31. At this time, the cleaning liquid above the mixing bin 11 can be sprayed into the mixing bin 11 through the exhaust holes to clean the inside of the mixing bin 11. At the same time, the automatic opening of the sealing disc 42 at the discharge port can quickly clean the inside of the mixing bin 11.

[0093] Compared with the traditional cleaning settings, with the present invention, when the mixture is discharged, the device of the present invention can not only effectively filter bubbles, but also ensure the cleanliness of the mixing barrel through precise cleaning processes. The automated operation design effectively improves work efficiency and safety, and at the same time also brings a more convenient and efficient mixing and cleaning experience to users.
