Description

Technical Field

[0001] This utility model relates to the field of denitrification equipment technology, specifically to a denitrification system that utilizes dual ultrasonic equipment to deeply dissolve organic amines. Background Technology

[0002] Organic amine denitrification technology is a denitrification technique that utilizes a denitrification agent solution to reduce nitrogen oxides (NOx). Currently, the denitrification agent solution, such as an organic amine solution, is generally mixed with dilution water, then distributed into various nozzles through a distribution header. Finally, the organic amine solution is sprayed onto the nozzles to carry out the reaction and denitrification.

[0003] In dilution water, the hydrogen bonds between water molecules are very strong. Therefore, when organic amines are added to water, water molecules will first interact with the hydrophilic part of the organic amine molecule. However, due to the presence of the hydrophobic part of the organic amine molecule, water molecules cannot completely penetrate into the molecular structure, resulting in incomplete dissolution. This incomplete dissolution makes the organic amine solution and dilution water mix poorly, and easily forms local high concentration and local low concentration areas in the mixture, affecting the overall denitrification effect. Utility Model Content

[0004] The present invention aims to provide a denitrification system that utilizes dual ultrasonic equipment to deeply dissolve organic amines, thereby solving the problem of poor mixing effect between organic amine solutions and dilution water, which affects the overall denitrification effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a denitrification system for deep dissolution of organic amines using dual ultrasonic equipment, comprising: a dilution water tank, a denitrification agent storage tank, and a first pressure stabilizing tank, a distribution pipe, and a spray gun connected in sequence. The dilution water tank and the denitrification agent storage tank are both connected to the first pressure stabilizing tank. The denitrification agent storage tank is equipped with an ultrasonic device, which is used to break down the organic amines in the denitrification agent storage tank. The first pressure stabilizing tank is equipped with a first ultrasonic plate, which is fixed to the inner wall of the first pressure stabilizing tank. The connection between the dilution water tank and the first pressure stabilizing tank is located at the bottom of the first pressure stabilizing tank, and the connection between the denitrification agent storage tank and the first pressure stabilizing tank is also located at the bottom of the first pressure stabilizing tank.

[0006] The principle of this scheme is as follows: The ultrasonic equipment is turned on to break down the organic amine in the denitrification agent storage tank. By breaking down the organic amine, it can be decomposed into smaller particles, thereby significantly increasing the surface area and greatly increasing the contact area between water molecules and organic amine molecules. The ultrasonically treated organic amine solution is added to the first pressure stabilizing tank, and dilution water from the dilution water tank is added to the first pressure stabilizing tank. Then, the first ultrasonic plate is turned on. The vibration of the ultrasonic waves can promote the uniform flow of the liquid and promote the uniform mixing of the organic amine solution and dilution water. The mixed solution is distributed through the distribution pipe to the spray gun and sprayed into the corresponding equipment for denitrification.

[0007] Advantages of this solution: After crushing and thorough dissolution, organic amines and water molecules can come into contact more easily. Organic amine molecules can better interact with water molecules through hydrogen bonding, dipole-dipole interactions, and other processes, further improving the solubility and mixing effect of organic amines in water, allowing the two to mix thoroughly. The smaller organic amine particles after crushing can quickly form a uniform solution with water molecules, avoiding problems such as incomplete dissolution or slow dissolution. First, the organic matter is crushed by ultrasonic cavitation using micro-point focusing and a large focal zone, and then the organic amine solution and dilution water are ultrasonically mixed. This double ultrasonic treatment ensures that the organic amine and dilution water are mixed evenly, guaranteeing the denitrification effect.

[0008] Preferably, the system further includes a second pressure stabilizing tank, which connects the first pressure stabilizing tank and the distribution pipes. Multiple distribution pipes are evenly distributed on the second pressure stabilizing tank. A second ultrasonic plate is installed in the second pressure stabilizing tank and fixedly mounted on its inner wall. The second ultrasonic plate stirs and mixes the liquid in the second pressure stabilizing tank, evenly dispersing the substances in the liquid, reducing local flow unevenness, and ensuring uniform flow distribution at each distribution pipe. Finally, the denitrification agent solution is discharged from the distribution pipe. The second ultrasonic plate further disperses the substances in the liquid, preventing sedimentation or stratification, and effectively improves fluid flowability, reducing local flow unevenness. This contributes to a more uniform flow distribution at each outlet, facilitating control of the denitrification dosage at each distribution pipe, and ensuring the quality of flue gas denitrification.

[0009] Preferably, the distribution pipes are evenly distributed at the bottom of the second pressure stabilizing tank, which further makes the pressure distribution of each outlet more uniform and the flow distribution of each liquid outlet more uniform, making it easier to control the denitrification dosage of each distribution pipe and ensuring the quality of flue gas denitrification.

[0010] Preferably, the system also includes a pressure stabilizing pipe, with its two ends connected to a first pressure stabilizing tank and a second pressure stabilizing tank, respectively. A pressure stabilizing valve is installed on the pressure stabilizing pipe. By setting up the pressure stabilizing valve and the pressure stabilizing tank, the pressure in the fluid system is controlled and maintained to prevent excessively high or low pressure, thereby ensuring the safe operation of equipment and pipelines.

[0011] Preferably, the connection point between the pressure stabilizing pipe and the first pressure stabilizing tank is close to the bottom of the first pressure stabilizing tank, and the connection point between the pressure stabilizing pipe and the second pressure stabilizing tank is close to the bottom of the second pressure stabilizing tank.

[0012] Preferably, the diameter of the distribution pipe is smaller than the diameter of the pressure stabilizing pipe. This prevents a rapid drop in the liquid level in the second pressure stabilizing tank when multiple distribution pipes are opened simultaneously.

[0013] Preferably, the distribution pipe is equipped with a switch valve, which allows for convenient control of opening and closing of the distribution pipe.

[0014] Preferably, the distribution pipe is equipped with a plunger pump, which pressurizes the solution and enhances its penetrating power.

[0015] Preferably, the system also includes a transfer pump, wherein the dilution water tank is connected to the first pressure stabilizing tank via the transfer pump, and the denitrification agent storage tank is connected to the first pressure stabilizing tank via the transfer pump. The transfer pump allows for control of the addition rate of dilution water and denitrification agent, facilitating adjustment of the dilution water and denitrification agent ratio.

[0016] Figure 1 This is a structural schematic diagram of an embodiment of the present utility model. Detailed Implementation

[0017] The following detailed description illustrates the specific implementation method:

[0018] The reference numerals in the accompanying drawings include: 1. dilution water tank; 2. denitrification agent storage tank; 3. plunger pump; 4. spray gun; 5. first pressure stabilizing tank; 6. pressure stabilizing pipe; 7. second pressure stabilizing tank; 8. distribution pipe; 9. first ultrasonic plate; 10. second ultrasonic plate; and 11. ultrasonic equipment.

[0019] Example:

[0020] A denitrification system that utilizes dual ultrasonic equipment to deeply dissolve organic amines, such as... Figure 1 As shown, it includes: a dilution water tank 1, a denitrification agent storage tank 2, and a first pressure stabilizing tank 5, a distribution pipe 8, and a spray gun 4 connected in sequence.

[0021] The dilution water tank 1 is used to store dilution water, and the denitrification agent storage tank 2 is used to store denitrification agent. The composition of the dilution water and the denitrification agent are based on existing technology and will not be described in detail here.

[0022] Both the dilution water tank 1 and the denitrification agent storage tank 2 are connected to the first pressure stabilizing tank 5. The connection point between the dilution water tank 1 and the first pressure stabilizing tank 5 is located at the bottom of the first pressure stabilizing tank 5, and the connection point between the denitrification agent storage tank 2 and the first pressure stabilizing tank 5 is also located at the bottom of the first pressure stabilizing tank 5. A transfer pump is also included, connecting both the dilution water tank 1 and the denitrification agent storage tank 2 to the first pressure stabilizing tank 5. The transfer pump allows for control of the addition rate of dilution water and denitrification agent, facilitating adjustment of the dilution water and denitrification agent ratio. Flow valves can also be installed on the corresponding pipelines to further control the ratio of dilution water and denitrification agent. The dilution water tank 1 adopts a vertical cylindrical structure with an integrated stainless steel spiral coil heat exchanger, and the water temperature is controlled by a PID temperature control module.

[0023] An ultrasonic device 11 is installed on the denitrification agent storage tank 2. The ultrasonic device 11 is used to break down the organic amines in the denitrification agent storage tank 2. Activating the ultrasonic device 11 breaks down the organic amines in the denitrification agent storage tank 2, decomposing them into smaller particles, thereby significantly increasing the surface area and greatly increasing the contact area between water molecules and organic amine molecules. After breaking down and fully dissolving, it ensures that organic amine and water molecules can contact more easily. Organic amine molecules can better interact with water molecules through hydrogen bonding, dipole-dipole interactions, etc., further improving the solubility and mixing effect of organic amine in water, allowing for thorough mixing. The smaller organic amine particles after breaking down can quickly form a homogeneous solution with water molecules, avoiding problems of incomplete dissolution or slow dissolution. In this solution, the ultrasonic device 11 is an ultrasonic plate, which, based on existing technology, will not be described in detail here.

[0024] The first pressure stabilizing tank 5 is equipped with a first ultrasonic plate 9, which is fixed to the inner wall of the first pressure stabilizing tank 5. The ultrasonically treated organic amine solution is added to the first pressure stabilizing tank 5, and dilution water from the dilution water tank 1 is added to the first pressure stabilizing tank 5. Then, the first ultrasonic plate 9 is turned on. The ultrasonic vibration promotes the uniform flow of the liquid, causing the organic amine solution and dilution water to mix evenly. When the ultrasonic waves propagate in the organic amine liquid, they generate local bubbles or cavitation. These bubbles break under the action of the ultrasonic waves, forming strong shock waves that stir the surrounding liquid, resulting in a uniform mixture of organic amine and dilution water. In this scheme, the organic matter is first broken up by ultrasonic cavitation using micro-point focusing and a large focal zone, followed by ultrasonic mixing of the treated organic amine solution and dilution water. This double ultrasonic treatment ensures uniform mixing of the organic amine and dilution water, guaranteeing the denitrification effect.

[0025] The first pressure-stabilizing tank 5 has a compressed air inlet at its top. The compressed air flow enhances the fluidity of the liquid, prevents stagnant areas, and improves stirring efficiency. Ultrasonic vibration promotes uniform liquid flow, allowing the combination of airflow and vibration to effectively drive liquid mixing. The first pressure-stabilizing tank 5 has symmetrically arranged compressed air inlets. This symmetrical arrangement ensures that the airflow is evenly distributed throughout the tank, preventing airflow accumulation on one side and resulting in uneven distribution. The compressed air inlets and the first ultrasonic plate 9 are staggered. This staggered arrangement ensures that the compressed air does not affect the disturbance of the denitrification agent solution by the first ultrasonic plate 9.

[0026] The first ultrasonic plate 9 is vertically positioned at the center of the bottom of the first pressure-stabilizing tank 5. The bottom is a critical area for liquid flow; the location of the first ultrasonic plate 9 here effectively causes the liquid at the bottom of the container to flow upwards, resulting in better mixing of the entire liquid system. The first ultrasonic plate 9 effectively agitates the liquid at the bottom, preventing material sedimentation. Its central placement at the bottom ensures uniform stirring within the liquid. By placing the first ultrasonic plate 9 at the center of the bottom, the gravitational distribution of the liquid can be fully utilized, reducing energy waste. In this embodiment, the first ultrasonic plate 9 can be installed on the first pressure-stabilizing tank 5 using bolts or other methods.

[0027] The system also includes a second pressure stabilizing tank 7, which connects the first pressure stabilizing tank 5 and the distribution pipes 8. Multiple distribution pipes 8 are evenly distributed on the second pressure stabilizing tank 7. A second ultrasonic plate 10 is installed inside the second pressure stabilizing tank 7, fixedly mounted on its inner wall. The second ultrasonic plate 10 stirs and mixes the liquid in the second pressure stabilizing tank 7, evenly dispersing the substances in the liquid, reducing local flow unevenness, and ensuring uniform flow distribution at each distribution pipe 8. Finally, the denitrification agent solution is discharged from the distribution pipe 8. The second ultrasonic plate 10 further disperses the substances in the liquid, preventing sedimentation or stratification, and effectively improves fluid flowability, reducing local flow unevenness. This contributes to a more uniform flow distribution at each outlet, facilitating control of the denitrification dosage at each distribution pipe 8 and ensuring the quality of flue gas denitrification. The first ultrasonic plate 9 and the second ultrasonic plate 10 are devices used for ultrasonic applications. Their basic function is to convert electrical energy into mechanical vibration energy (ultrasound) to stir the organic amine solution. Ultrasonic plates are existing technology, and this solution does not improve upon them; therefore, they are not described in detail here.

[0028] The distribution pipes 8 are evenly distributed at the bottom of the second pressure stabilizing tank 7, which further makes the pressure distribution of each outlet more uniform and the flow distribution of each liquid outlet more uniform, making it easier to control the denitrification dosage of each distribution pipe 8 and ensuring the quality of flue gas denitrification.

[0029] The first pressure stabilizing tank 5 and the second pressure stabilizing tank 7 are both cylindrical and made of corrosion-resistant and high-temperature-resistant materials, such as stainless steel.

[0030] It also includes a pressure stabilizing pipe 6, whose two ends are connected to the first pressure stabilizing tank 5 and the second pressure stabilizing tank 7, respectively. A pressure stabilizing valve is installed on the pressure stabilizing pipe 6. The pressure stabilizing pipe 6 controls the denitrification solution and dilution water to prevent interference. By setting up the pressure stabilizing valve and pressure stabilizing tanks, it controls and maintains the pressure stability of the fluid system, preventing excessively high or low pressures, thus ensuring the safe operation of equipment and pipelines. In this solution, the main body of the pressure stabilizing pipe 6 is made of S304 stainless steel.

[0031] The connection point between the pressure stabilizing pipe 6 and the first pressure stabilizing tank 5 is located near the bottom of the first pressure stabilizing tank 5, and the connection point between the pressure stabilizing pipe 6 and the second pressure stabilizing tank 7 is located near the bottom of the second pressure stabilizing tank 7. This design layout ensures that when the liquid flows in the pressure stabilizing pipe 6, it can fully guide the solution in the first pressure stabilizing tank 5 and the second pressure stabilizing tank 7, while reducing the possibility of liquid stagnation in the tanks, thereby improving the flow efficiency and stability of the system.

[0032] A plunger pump 3 is installed on the distribution pipe 8. The plunger pump 3 pressurizes the solution, giving it stronger penetrating power and enabling more effective and even distribution of the denitrification agent solution into each nozzle, thereby improving the diffusion effect and denitrification efficiency of the denitrification agent solution within the furnace. The diameter of the distribution pipe 8 is smaller than that of the pressure stabilizing pipe 6. This design aims to prevent a rapid drop in the liquid level in the second pressure stabilizing tank 7 when multiple distribution pipes 8 are open simultaneously, thus maintaining pressure balance within the system and ensuring a stable supply of solution. A switch valve is installed on the distribution pipe 8. By opening and closing the switch valve, the on / off state of the distribution pipe 8 can be flexibly controlled, thereby achieving precise regulation of the denitrification agent solution flow rate. This design not only improves the operational flexibility of the system but also allows for rapid cutoff of the liquid supply when needed, ensuring the safe operation of the system.

[0033] The specific implementation process is as follows:

[0034] The ultrasonic device 11 is activated to break down the organic amine in the denitrification agent storage tank 2. By breaking down the organic amine, it can be decomposed into smaller particles, thereby significantly increasing the surface area and greatly increasing the contact area between water molecules and organic amine molecules. The ultrasonically treated organic amine solution is added to the first pressure stabilizing tank 5, and dilution water from the dilution water tank 1 is added to the first pressure stabilizing tank 5. Then, the first ultrasonic plate 9 is activated. The vibration of the ultrasonic waves can promote the uniform flow of the liquid and promote the uniform mixing of the organic amine solution and dilution water. The mixed solution enters the second pressure stabilizing tank 7 through the pressure stabilizing pipe 6. The pressure in the fluid system is controlled and maintained by setting a pressure stabilizing valve. The second ultrasonic plate 10 stirs and mixes the liquid in the second pressure stabilizing tank 7, uniformly disperses the substances in the liquid, reduces local flow unevenness, and makes the flow distribution uniform at each distribution pipe 8. Finally, the denitrification agent solution is discharged from the distribution pipe 8 and then flows from the distribution pipe 8 to the spray gun 4, and is sprayed from the spray gun 4 into the corresponding equipment for denitrification.

[0035] The advantages of this scheme are as follows: First, the organic matter is broken down by ultrasonic cavitation through micro-point focusing and large focal zone. Then, the organic amine solution and dilution water are ultrasonically mixed. This double ultrasonic treatment ensures that the organic amine and dilution water are evenly mixed, guaranteeing the denitrification effect. The second ultrasonic plate 10 further disperses the substances in the liquid, preventing precipitation or stratification. It also effectively improves the fluid flowability and reduces local flow unevenness, thus contributing to a more uniform flow distribution at each outlet. This facilitates the control of the denitrification dosage in each distribution pipe 8, ensuring the quality of flue gas denitrification. The pressure is controlled and maintained in the fluid system by setting up pressure stabilizing valves and pressure stabilizing tanks to prevent excessively high or low pressure, ensuring the safe operation of equipment and pipelines.
