Overview of Silicon Carbide Desulfurization Nozzle

Silicon Carbide Desulfurization Nozzle is a key component used in desulfurization systems. It is usually made of silicon carbide material, with high strength, high hardness, high temperature, wear and corrosion resistance and other excellent performance. With reasonable design, it can make the desulfurization agent sprayed evenly atomized, which is widely used in the field of flue gas desulfurization in electric power, chemical industry and other industries.

Features of Silicon Carbide Desulfurization Nozzle

Silicon Carbide Desulfurization Nozzle has the following significant features:

High abrasion resistance: Silicon carbide itself is extremely hard, second only to diamond. In the process of desulfurization, it can withstand the high-speed flow of solid-containing liquid droplets, not easy to wear, extending the service life of the nozzle, reducing the frequency of maintenance and replacement due to nozzle wear.

Strong corrosion resistance: silicon carbide has good chemical stability, strong resistance to the acid in the desulfurization agent, can maintain stable performance in harsh chemical environments, and will not affect the spray effect and structural integrity of the nozzle due to corrosion.

Good spraying effect: after precise design and processing, the silicon carbide desulfurization nozzle can achieve uniform spray distribution, so that the desulfurization agent is in full contact with the flue gas, and improve the efficiency of desulfurization. The spray angle and droplet size can be customized according to different desulfurization process requirements to meet the needs of various application scenarios.

Good insulation: Silicon Carbide has excellent insulation properties, which is very important in some FGD systems that require electrical performance to avoid equipment failure or safety hazards caused by electrical problems.

Applications of Silicon Carbide Desulfurization Nozzle

Silicon Carbide Desulfurization Nozzle has a wide range of applications in many fields, mainly in the following areas:

Power industry: Thermal power plants are important application scenarios. In the coal-fired power generation process will produce a large number of flue gas containing sulfur dioxide, silicon carbide desulfurization nozzle installed in the desulfurization tower, the desulfurization agent, such as limestone slurry, etc. in a fine mist spray, and the flue gas to fully contact with the chemical reaction occurs, the sulfur dioxide is effectively removed, so that the emission of flue gas to meet the environmental protection standards to reduce the pollution of the atmosphere.

Chemical industry: many chemical production processes will also produce sulfur-containing waste gas, such as petroleum refining, sulfuric acid production and so on. Silicon carbide desulfurization nozzle can accurately spray the desulfurizer to the reaction area according to the specific working conditions of chemical production and the characteristics of the exhaust gas to achieve efficient desulfurization, to ensure that the exhaust gas in the chemical production process meets the emission standards, and at the same time, it can also protect the production equipment from damage due to corrosion of acidic gases.

Iron and steel industry: In the process of iron and steel smelting, coke oven gas desulfurization and flue gas desulfurization of sintering machine are inseparable from silicon carbide desulfurization nozzle. It can evenly spray the desulfurization liquid, so that the desulfurization reaction is fully carried out, reducing the sulfur content in the flue gas, reducing the pollution of the environment, and helping iron and steel enterprises to realize green production.

Garbage incineration industry: Garbage incineration will produce flue gas containing sulfur dioxide and other pollutants. Silicon carbide desulfurization nozzle by atomizing the desulfurizer sprayed into the flue gas, can effectively remove the sulfur oxides therein, to avoid harm to the surrounding environment and the health of the residents, to protect the garbage incineration plant’s safe and environmentally friendly operation.

5 FAQs of  Silicon Carbide Desulfurization Nozzle

Q1：Why choose silicon carbide desulfurization nozzle?

Silicon carbide is second only to diamond in hardness, and its wear resistance is 5-10 times higher than that of ordinary metals，its chemical stability is excellent, and it can resist the long-term erosion of limestone slurry, acidic flue gas and other corrosive media. In addition, silicon carbide’s high temperature resistance (can withstand 1400 ℃ high temperature) and thermal shock resistance (rapid cold and heat without rupture) so that it is still able to maintain stable performance in complex working conditions.

Q2: What is the difference between silicon carbide desulfurization nozzle and other materials (such as ceramic and metal)?

Ceramic nozzle: brittle, easy to rupture due to particle flushing or sudden temperature change, shorter life. Metal nozzle: poor corrosion resistance, easy to be corroded in acidic environments, and insufficient wear resistance. Silicon carbide nozzle: better overall performance, especially in the abrasion resistance, corrosion resistance, high temperature resistance far beyond the traditional materials, service life of up to 5-10 years.

Q3：How to choose the right type of silicon carbide desulfurization nozzle?

Hollow cone nozzle: suitable for scenes requiring large coverage area (such as power plant desulfurization tower), spray angle 60°-120°. Solid cone nozzle: uniform droplet distribution, suitable for high solid content slurry, strong anti-clogging ability. Connection: thread, flange, clamp, etc., need to be matched with piping system. Flow rate and pressure: calculated according to the size of desulfurization tower, slurry circulation, general working pressure 0.2-0.5MPa. Particle passage: choose the model with larger diameter of runner (such as spiral nozzle), to avoid clogging of impurities in the slurry.

Q4: Are there differences in nozzle selection for different industries?

Yes. Electric power industry: preferred hollow cone bidirectional nozzle, can be sprayed up and down at the same time, covering a large area. Chemical industry: need to resist strong corrosive media, recommended reaction sintered silicon carbide nozzle, no internal separation parts, anti-clogging ability. Iron and steel industry: coke oven gas desulfurization needs small angle jet nozzle, enhance the impact, prevent slurry precipitation.

Q5：What issues need to be paid attention to when installing silicon carbide desulfurization nozzle?

Sealing treatment: use high temperature resistant sealing ring to avoid slurry leakage; the bolts need to be tightened evenly to prevent bias when flange connection. Direction adjustment: the nozzle needs to be installed vertically downward to ensure uniform spray coverage and avoid angular deviation leading to a decrease in local desulfurization efficiency. Anti-loosening measures: For occasions with high vibration, apply anti-loosening glue on the threaded connection or use clamps to fix it.
