Description

Technical Field

[0001] This utility model relates to the field of desulfurization technology, and in particular to a nozzle anti-clogging component for desulfurization equipment. Background Technology

[0002] Desulfurization refers to the process of removing sulfur from fuel before combustion and desulfurizing flue gas before emission. It is one of the important technical measures for preventing and controlling air pollution. With industrial development and the improvement of people's living standards, the demand for energy is constantly increasing, and SO2 in coal-fired flue gas has become a major cause of air pollution. Reducing SO2 pollution has become an urgent task for current air pollution control. Many flue gas desulfurization processes have been widely used in industry. A desulfurization nozzle is a type of desulfurization environmental protection equipment that sprays limestone slurry under high pressure to react with sulfides in the flue gas, achieving a desulfurization effect. It is an important means of reducing sulfide emissions in industrial production and protecting the atmospheric environment.

[0003] A search revealed a patent with publication number CN216322843U entitled "Anti-clogging Component for Nozzles in Desulfurization Equipment." The patent addresses the technical problem of frequent and severe blockages in pipes and spray nozzles during desulfurization equipment operation, resulting in poor desulfurization performance, failure to meet ultra-low emission requirements, and inability to operate normally. The solution involves the coordinated use of an anti-clogging block, a desulfurization nozzle body, a limiting rod, a housing, and a positioning mechanism. The anti-clogging block is placed inside the nozzle body, and the limiting rod enters the housing. The positioning mechanism then fixes the limiting rod. The anti-clogging block effectively prevents limewater from caking and clogging the nozzle body, thus solving the problem of frequent and severe blockages in pipes and spray nozzles during desulfurization equipment operation, leading to poor desulfurization performance, failure to meet ultra-low emission requirements, and inability to operate normally. However, the following drawback remains: limestone slurry can condense on the inner wall of the nozzle during long-term spraying, affecting the spraying effect. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a nozzle anti-clogging component for desulfurization equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Preferably, a slurry inlet pipe is fixedly connected to one end of the circumference of the slurry guide shell, and a flow regulating valve is provided inside the slurry inlet pipe.

[0008] Preferably, the slurry jet head has multiple jet nozzles around its circumference.

[0009] Preferably, the upper part of the fixed platform is a frustum shape, narrower at the top and wider at the bottom.

[0010] Preferably, the scraping mechanism includes multiple scraping rings at equal intervals, and multiple support rods at equal angles are inserted between the multiple scraping rings. The inner side of the scraping ring at the bottom of the scraping mechanism is fixedly connected to the ends of the three support rods.

[0011] Preferably, the cross-section of the outer side of the scraper ring is triangular, and the cross-section of the inner side of the scraper ring is semi-circular.

[0012] Preferably, the stiffness coefficients of the support spring and the return spring decrease sequentially.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model proposes a nozzle anti-clogging component for desulfurization equipment. The desulfurization nozzle is composed of a nozzle body, a slurry guide shell, a slurry inlet pipe, and a slurry spray head. Internally, it includes a sleeve, a T-shaped rod, and a scraper ring mechanism. A flow regulating valve is installed inside the slurry inlet pipe. The flow regulating valve intelligently controls the slurry flow rate per unit time. The support spring is located outside the circumference of the return spring, and the stiffness coefficients of the support spring and return spring decrease sequentially, causing the impact force of the slurry on the fixed platform and support rod to change periodically. This causes the scraper mechanism to move up and down cyclically along the inner circumference of the nozzle body, effectively scraping away the slurry retained on its inner wall. Furthermore, the cross-section of the outer circumference of the scraper ring is triangular, efficiently and quickly scraping away slurry particles adhering to its inner wall, ensuring good spraying effect when the desulfurization nozzle sprays slurry.
