Abstract
Description
Technical Field
[0001] This utility model relates to the field of wet flue gas desulfurization and purification, specifically to a single-fluid solid nozzle. Background Technology
[0002] Currently, in wet desulfurization purification systems, calcium sulfate (CaSO4) and calcium sulfite (CaSO3) are prone to scaling inside pipe components (including nozzles) during long-term use, causing blockages in the pipeline system and nozzles, affecting long-term performance. Because the flow area of existing spiral nozzles and other nozzle structures is relatively small, they are more likely to form blockages in a short period of time, affecting the normal operation of the purification system, reducing the desulfurization efficiency of the purification system, and resulting in a phenomenon where the purification effect is good at the time of commissioning but poor after commissioning. Utility Model Content
[0003] To address the aforementioned issues, this invention provides a single-fluid solid nozzle that simultaneously achieves full coverage of the desulfurization slurry on the flue gas flow surface during desulfurization system operation, enhances gas-liquid mixing, improves gas-liquid mixing efficiency, increases the desulfurization efficiency of the wet desulfurization system, and reduces nozzle resistance.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a single-fluid solid nozzle, comprising a flange interface, a conditioning chamber, a pressure boosting nozzle, and a nozzle opening, wherein the upper and lower ends of the conditioning chamber are respectively connected to the flange interface and the pressure boosting nozzle, and the nozzle opening is disposed at the bottom of the pressure boosting nozzle, and the nozzle opening diffusion angle is 90° to 120°.
[0005] Preferably, the flow area of the conditioning chamber is 2.5 to 3 times the inner circle area of the flange interface.
[0006] Preferably, the angle between the upper wall of the tempering cavity and the axis of the tempering cavity is 65° to 80°, and the joint between the upper and lower parts of the tempering cavity is streamlined with a minimum radius of curvature of not less than 5mm.
[0007] Preferably, the minimum flow area of the booster nozzle is 0.8 times the inner circle area of the flange interface.
[0008] Preferably, the pressure boosting nozzle has a streamlined structure and a minimum radius of curvature of not less than 10 mm.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: It provides a single-fluid solid nozzle that adopts wet purification and desulfurization. During the operation of the system equipment, the fluid flow direction in the pipeline is conditioned and mixed through the conditioning chamber to achieve uniform distribution. Under the flow limiting effect of the pressure boosting nozzle, the static pressure in the conditioning chamber is increased. After the slurry is conditioned and pressurized, it is sprayed out from the nozzle. At the same time as the pressure is released instantly, the liquid is broken into droplets and sprayed into the flue gas. The nozzle diffusion angle determines the droplet diffusion angle, ensuring that the slurry is uniformly covered in the action area. Attached Figure Description

[0015] Example 1
[0016] like Figures 1 to 2 As shown, this utility model provides a single-fluid solid nozzle, including a flange interface 1, a conditioning chamber 2, a pressure boosting nozzle 3, and a nozzle 4. The upper and lower ends of the conditioning chamber 2 are respectively connected to the flange interface 1 and the pressure boosting nozzle 3. The nozzle 4 is located at the bottom of the pressure boosting nozzle 3, and the diffusion angle of the nozzle 4 is 90° to 120°.
[0017] Wet purification and desulfurization are adopted. During the operation of the system equipment, the fluid flow direction in the pipeline is adjusted and mixed through the conditioning chamber 2 to achieve uniform distribution. Under the flow restriction effect of the pressure boosting nozzle 3, the static pressure in the conditioning chamber 2 is increased. After conditioning and pressurization, the slurry is sprayed out from the nozzle 4. While releasing the pressure instantly, the liquid is broken into droplets and sprayed into the flue gas. The diffusion angle of the nozzle 4 determines the diffusion angle of the droplets, ensuring uniform coverage of the slurry in the action area.
[0018] Furthermore, the flow area of the conditioning chamber 2 is 2.5 to 3 times the inner circle area of the flange interface 1, the angle between the upper wall of the conditioning chamber 2 and the axis of the conditioning chamber 2 is 65° to 80°, and the joint between the upper and lower parts of the conditioning chamber 2 is streamlined with a minimum radius of curvature of not less than 5mm, so as to achieve fluid conditioning and rectification and achieve the goal of uniform liquid spraying in all directions.
[0019] Furthermore, the minimum flow area of the booster nozzle 3 is 0.8 times the inner circle area of the flange interface. The booster nozzle 3 has a streamlined structure and a minimum radius of curvature of not less than 10mm, so as to realize the hydraulic rise in the conditioning chamber and better achieve the goal of droplet breakage.
