[0002] Organic amine denitration technology is a kind of denitration technology using organic amine compound to reduce reaction of nitrogen oxide (NOx). Currently, denitration agent solution and dilution water are mixed, then distributed into each spray pipe through distribution main pipe, and finally organic amine solution is sprayed by spray pipe for reaction denitration.

[0016] Figure 1 The structure of the embodiment of the present application is shown in the schematic diagram. DETAILED DESCRIPTION

[0017] The specific embodiments are further described in detail as follows:

[0018] The reference signs in the drawings of the specification include: mixing pipe 1, first pressure tank 2, pressure regulating pipe 3, second pressure tank 4, distribution pipe 5, first ultrasonic plate 6, and second ultrasonic plate 7.

[0019] Example:

[0020] An organic amine solution using a pressure stabilizing tank, such as Figure 1 As shown, it includes: a mixing pipe 1, a first pressure stabilizing tank 2, a pressure stabilizing pipe 3, a second pressure stabilizing tank 4, and a distribution pipe 5 connected in sequence.

[0021] One end of the mixing pipe 1 is connected to the pressure stabilizing tank, and the other end of the mixing pipe 1 is equipped with a liquid inlet. The connection point between the mixing pipe 1 and the first pressure stabilizing tank 2 is close to the bottom of the first pressure stabilizing tank 2. The bottom connection design ensures that particles will not settle at the bottom of the tank, thereby reducing equipment maintenance and improving material uniformity. The outlet axis of the mixing pipe 1 forms a 45° angle with the tangent direction of the bottom of the first pressure stabilizing tank 2.

[0022] In this embodiment, the mixing tube 1 is a stainless steel tube. A compressed air inlet is provided at the top of the first pressure-stabilizing tank 2, and a first ultrasonic plate 6 is installed inside the first pressure-stabilizing tank 2, fixed to the inner wall of the first pressure-stabilizing tank 2. The airflow of compressed air enhances the fluidity of the liquid, preventing stagnant areas and improving stirring efficiency; the vibration of ultrasound promotes uniform liquid flow, allowing the combination of airflow and vibration to effectively drive liquid mixing.

[0023] The first pressure stabilizing tank 2 is symmetrically equipped with compressed air inlets. The symmetrical arrangement of the compressed air inlets ensures that the airflow is evenly distributed in the first pressure stabilizing tank 2, avoiding airflow accumulation on one side and resulting in uneven airflow distribution.

[0024] The first ultrasonic plate 6 is vertically positioned at the center of the bottom of the first pressure-stabilizing tank 2. The bottom is a critical area for liquid flow; the location of the first ultrasonic plate 6 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 6 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 6 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 6 can be installed on the first pressure-stabilizing tank 2 using bolts or other methods.

[0025] The first pressure stabilizing tank 2 and the second pressure stabilizing tank 4 are both cylindrical and made of corrosion-resistant and high-temperature-resistant materials, such as stainless steel.

[0026] In this embodiment, the compressed air inlet and the first ultrasonic plate 6 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 6. In this embodiment, the offset angle θ between the compressed air inlet and the centerline of the first ultrasonic plate 6 is 120°.

[0027] The one end of the distribution pipe 5 is communicated with the second pressure tank 4, and the other end of the distribution pipe 5 is provided with a liquid outlet; a plurality of distribution pipes 5 are uniformly arranged on the side wall of the second pressure tank 4, and the distribution pipes 5 are circumferentially distributed on the side wall above the position close to the bottom of the second pressure tank 4. The second ultrasonic plate 7 is arranged in the second pressure tank 4, and the second ultrasonic plate 7 is fixedly installed on the inner wall of the second pressure tank 4. In the embodiment, the second ultrasonic plate 7 can be fixedly installed on the inner wall of the second pressure tank 4 through bolts, and further connected through flange bolts and provided with a lock washer. The second ultrasonic plate 7 stirs and mixes the liquid in the second pressure tank 4, uniformly disperses the substances in the liquid, reduces the local flow unevenness, and makes the flow distribution of each distribution pipe 5 uniform, and finally the denitration agent solution is discharged from the distribution pipe 5. The second ultrasonic plate 7 further disperses the substances in the liquid, avoids the precipitation or stratification of the substances, and can effectively improve the fluidity of the fluid, reduce the local flow unevenness, thereby helping the flow distribution of each liquid outlet to be more uniform, facilitating the control of the denitration agent amount of each distribution pipe 5, and ensuring the quality of flue gas denitration; the perturbation vibration of the ultrasonic wave can destroy the structure or agglomerate in the liquid, thereby reducing the fluid resistance and making the flow of each liquid outlet more stable and uniform. The first ultrasonic plate 6 and the second ultrasonic plate 7 are a device for ultrasonic application, and its basic function is to convert electrical energy into mechanical vibration energy (ultrasonic wave). When the ultrasonic wave propagates in the organic amine solution, the liquid flows and stirs and mixes, and bubbles are generated in the organic amine solution, and the bubbles break to generate strong shock waves to stir and mix the organic amine solution. The ultrasonic plate is a prior art, and the present scheme does not improve it, and will not be described in detail here.

[0028] The pressure stabilizing pipe 3 is provided with a pressure stabilizing valve, the pressure stabilizing pipe 3 controls the denitration solution and the dilution water without interference, the pressure stabilizing valve is arranged to control and maintain the pressure in the fluid system stable, prevents the pressure from being too high or too low, to ensure the safe operation of the equipment and the pipeline. The communication position of the pressure stabilizing pipe 3 and the first pressure tank 2 is close to the bottom of the first pressure tank 2, and the communication position of the pressure stabilizing pipe 3 and the second pressure tank 4 is close to the bottom of the second pressure tank 4. In the present scheme, the pressure stabilizing pipe 3 is made of S304 stainless steel.

[0029] The second ultrasonic plate 7 is located above the communication position of the pressure stabilizing pipe 3 and the second pressure tank 4. The diameter of the distribution pipe 5 is smaller than the diameter of the pressure stabilizing pipe 3, so that when a plurality of distribution pipes 5 are opened at the same time, the liquid level in the second pressure tank 4 does not drop rapidly. The distribution pipe 5 is provided with an on-off valve, and the on-off valve is convenient for controlling the opening and closing of the distribution pipe 5.

[0030] The specific implementation process is as follows:

[0031] The denitrification agent solution enters the first pressure stabilizing tank 2 from the mixing pipe 1. Compressed air is added into the first pressure stabilizing tank 2 through the compressed air inlet. At the same time, the first ultrasonic plate 6 is turned on. The first ultrasonic plate 6 can effectively agitate the liquid at the bottom and effectively prevent material sedimentation. Then, the uniformly mixed denitrification agent solution enters the second pressure stabilizing tank 4 from the pressure stabilizing pipe 3. The pressure in the fluid system is controlled and maintained by setting a pressure stabilizing valve. The second ultrasonic plate 7 stirs and mixes the liquid in the second pressure stabilizing tank 4, evenly disperses the substances in the liquid, reduces local flow unevenness, and makes the flow distribution uniform at each distribution pipe 5. Finally, the denitrification agent solution is discharged from the distribution pipe 5.

[0032] This solution effectively agitates the liquid at the bottom by setting up a first ultrasonic plate 6, preventing material sedimentation. A second ultrasonic plate 7 further disperses substances in the liquid, preventing sedimentation or stratification, while also improving fluid flowability, reducing localized flow unevenness, and making the flow distribution at each outlet more uniform. This facilitates control of the denitrification dosage in each distribution pipe 5, ensuring the quality of flue gas denitrification. A pressure stabilizing valve controls and maintains pressure stability in the fluid system, preventing excessively high or low pressures to ensure the safe operation of equipment and pipelines.
