Silicon carbide nozzle The number of nozzles is closely related to the volume of smoke that needs to be treated. Generally, the total spray volume is calculated based on the liquid-to-gas ratio; primarily, silicon carbide ceramic nozzles are used, and the number of nozzles is determined by the specific nozzle flow rate and spray droplet size. Now, let’s take a closer look at the factors that affect the efficiency of silicon carbide nozzles!
I. Factors Affecting the Efficiency of Silicon Carbide Nozzles
1. The factors influencing desulfurization with silicon carbide nozzles are related to nozzle flow rate, nozzle pressure drop, nozzle structural parameters, and other factors. Reducing system costs is another key consideration. High-flow-rate nozzles have fewer restrictions and strong resistance to clogging, which can effectively lower operating costs. However, the flow rate of silicon carbide nozzles significantly affects the economic viability of the desulfurization system. Selecting high-flow-rate nozzles can reduce the total number of nozzles required. The maximum allowable flow rate for different silicon carbide nozzles is limited by their atomization performance.
2. Atomization performance of the desulfurization nozzle, Silicon carbide nozzle As the inlet pressure increases, the pressure drop across the nozzle also increases, leading to a greater flow rate through the nozzle. If, after atomization, the liquid provided by the limestone slurry has an insufficient contact surface area, this will directly affect the desulfurization efficiency. The uniform diameter of the atomized slurry droplets will decrease.
3. The particle size distribution of the water mist sprayed by nozzles is critical for many applications, and silicon carbide nozzles can reduce investment and ensure the system operates economically.
II. Several types of desulfurization nozzles are suitable for use in silicon carbide desulfurization towers.
1. Determine the number of coating layers and the number of nozzles based on the slurry flow rate and the average coverage area of the nozzle.
2. The average coverage area of the nozzle is determined by the larger coverage area of the nozzle itself and the arrangement of the nozzles.
3. The wide coverage area of the nozzle is determined by the nozzle type.
4. The nozzle configuration is determined by the designer and generally covers the entire cross-section of the tower.
5. The slurry flow rate is determined by material balance calculations.
6. Material balance calculations are highly complex, and different design institutes employ various algorithms.
7. In the absence of material balance calculations, the slurry quantity can be selected based on experience.
It is necessary to consider the following two conditions.
1. System Requirements:
First, consider the pressure, flow rate, and number of nozzles. The pressure must take into account the pressure drop in the piping system. In other words, as the liquid flows through the pipeline to reach the nozzles, there will be a certain pressure loss.
2. Spray conditions
The spray angle determines the coverage area of the spray; generally, desulfurization systems use a coverage rate of 300% as a benchmark. When considering the number of desulfurization nozzles under system conditions, their angles must also be taken into account.
