Introduction to the advantages and application fields of flue gas desulfurization nozzles

The flue gas desulfurization nozzle is a solid cone or hollow cone spray nozzle, and the spray angle can range from 50° to 170°. At 3 bar pressure, the liquid flow rate range is 5.5-4140 liters/min. This compact nozzle features a non-clogging, coreless, straight-through flow path design that minimizes fluid clogging and maximizes fluid flow in a given size pipe. We can see some water sprayed into some fog in some parks. The nozzle we are talking about today is a flue gas desulfurization nozzle, so what are the advantages of the flue gas desulfurization nozzle? What are the main applications?

Introduction to the advantages of flue gas desulfurization nozzles

The main advantages of flue gas desulfurization nozzles are: good fogging performance, high spray efficiency, energy saving; solid fog crown, uniform droplet distribution; streamlined flow channel design, good anti-blocking performance, especially to prevent clogging of fibrous materials; nozzle It is a combined structure, and the main wearing parts such as spout and guide fluid can be selected from various materials such as silicon carbide, ceramics, plastics, alloy steel and polyurethane. The components can be replaced with each other individually to save operating costs to the greatest extent.

1. Improved anti-blocking performance

We designed the guide vanes in the guide body into an intersecting but not connected split structure. This ingenious design can not only change the direction of the fluid without resistance, but also smoothly pass through fibrous materials (grass roots, plastic ribbons, etc.) and particulate matter (Not more than one-half the diameter of the nozzle hole).

2. Structure optimization, wide application and low cost

The functional components of the flue gas desulfurization nozzle are manufactured in separate parts, and the combined installation structure makes the functional materials more rationally used: in the key parts such as the guiding fluid, the pre-swirl chamber, and the nozzle hole, high wear-resistant functional materials are used. Such as silicon carbide, metal alloys, etc., to meet the wear-resistant life of the nozzle; in some relatively unimportant parts where the nozzle and the pipeline are connected, functional materials with high mechanical strength, good impact resistance and good processing performance are used, such as plastic, Materials such as glass fiber reinforced plastics or metal alloys can only be used to the best of their abilities. This avoids functional waste in the use of materials, satisfies the functional and economical optimal configuration of the nozzle materials to the greatest extent, and improves the performance of the nozzles. It also saves the cost of manufacturing and use.

At the same time, the impact resistance of the nozzle is improved, and the installation is convenient; in addition, during the application process, what part is damaged can be replaced, which overcomes the disadvantage that other nozzles are partially damaged and needs to be replaced as a whole, and reduces the user’s cost of use. Due to the diversity of the material of the flow parts, the nozzle can be applied to a variety of different types of working conditions, such as: clear liquid, slurry, strong corrosion, high wear and other fluids.

3. Good fogging performance and energy saving

The flue gas desulfurization nozzle adopts an annular, gradient, and elongated twisted guide fluid design, which minimizes the resistance of fluid self-consumption, strengthens the pre-swirl effect, and improves the fogging performance of the nozzle. Tested: Compared with the eccentric cone type sprinkler, the same fogging effect can be achieved by reducing the water column by 1.5 to 2 meters.

Therefore, in the desulfurization system, the pressure of the water supply can be appropriately reduced, the power consumption of the water supply pump can be reduced, and the electric energy and operating costs can be saved. Compared with the fogging performance of the conical spiral nozzle, it overcomes the deficiency of the former due to the uneven layering of the fog crown.

Flue gas desulfurization nozzle nozzles, desulfurization tower nozzles are widely used in the field of environmental protection, waste gas desulfurization, gas cooling, evaporative cooling, washing and leaching processes, dust removal, fire extinguishing, environmental protection chemical industry, desulfurization tower desulfurization, gas washing, ceramic factory dust removal tower , waste incineration plants, steel-making converters in flue dust removal and cooling, desulfurization, dust removal, washing, cooling, fire fighting, cleaning, decontamination, gas cooling, humidification, desulfurization and dust removal, spraying corrosive liquids, etc.
