The number of SIC nozzles has a certain relationship with the amount of smoke to be treated. In general, the total spray amount is calculated according to the liquid-gas ratio, mainly silicon carbide ceramic nozzles, and the number of nozzles is determined according to the specific nozzle flow rate and spray size. So, let’s understand what factors affect the efficiency of silicon carbide nozzles!
First, the factors affecting the efficiency of silicon carbide nozzle
1.the factors affecting the desulfurization of silicon carbide nozzle are related to the nozzle flow rate, nozzle pressure drop, nozzle structure parameters and other factors. Reduce system costs. The large flow nozzle has fewer restrictions and strong anti-clogging ability, which can effectively save operating costs. However, the flow rate of SIC nozzle affects the economy of desulfurization system. Choosing a nozzle with a large flow rate can reduce the total number of nozzles required, and the measurement of the large flow rate allowed by different SIC nozzles is limited by the atomization effect of the nozzle.
2. The atomization effect of the desulfurization nozzle, when the inlet pressure of the silicon carbide nozzle increases, the pressure drop of the nozzle increases, and the flow through the nozzle increases. If the liquid contact response surface area provided by the limestone slurry after spraying is too small, the desulfurization effect will be directly affected. The uniform diameter of atomized slurry drops decreases.
3.nozzle spray particle size distribution is very important for many applications, silicon carbide nozzle can reduce investment, complete the economic operation of the system.
Two, silicon carbide desulfurization tower suitable for the selection of several desulfurization nozzles
1. Determine the number of coating layers and nozzles according to the slurry flow rate and the average covered area of the nozzle.
2. The average covering area of the nozzle is determined by the larger covering area of the nozzle and the arrangement of the nozzle.
3. The wide cover area of the nozzle is determined by the nozzle type.
4. The configuration of the nozzle 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 calculation.
6, material balance is a very complex calculation, each design institute has different algorithms.
7. In the absence of material balance calculation, the size can be selected according to experience.
It is necessary to consider the following two conditions.
1. System conditions:
First consider the pressure, flow, nozzle number. Pressure The pressure drop of the piping system must be considered. That is to say, there is a certain pressure loss when the liquid reaches the nozzle through the pipe.
2, spray conditions
The spray Angle determines the coverage rate of the spray, and the general desulfurization system takes the coverage rate of 300% as the benchmark. The consideration of the number of desulfurization nozzles in the system conditions also needs to be determined by referring to its Angle.
