Silicon carbide nozzle desulfurization nozzle for power plant desulfurization, remove the power plant flue gas sulfur dioxide and some pollution gas. The application environment of the desulfurization nozzle is relatively harsh. The corrosion of sulfite and sulfuric acid, as well as the wear and corrosion caused by calcium sulfite, calcium sulfate and calcium carbonate particles, are the primary factors affecting the application function and service life of the nozzle.

Therefore, desulfurization nozzle materials generally choose silicon carbide or ceramics, they not only have outstanding resistance to sulfurous acid, sulfuric acid corrosion function, and its wear resistance ability is stainless steel (for example 316L) 15-30 times.

The atomized particle size and grading distribution of the desulfurization nozzle are important points. For wet spray desulfurization, the droplets are not finer, but moderate, neither affecting the desulfurization efficiency nor the efficiency of the mist eliminator. Generally, the atomized particle size is 0.8-1.5mm, accounting for more than 90% of the total droplets.

In addition, the design of spray layer also has a certain influence on desulfurization efficiency. The basic point is, in the spray layer work, can cover the flue gas, can not produce short-circuit flue gas situation. That is to say, the coverage rate on the design should be 150% or higher

The main effect on spray efficiency is the liquid pressure before the nozzle. The pressure is provided by circulating pump, so it is required that the proper selection of circulating pump should be made in combination with the design of slurry working liquid level and pipeline in the desulfurization tower. Before the nozzle pressure is large, atomizing droplets on the small, the greater the coverage; On the contrary, fog drops particles large, small coverage, smoke may appear short circuit.

Silicon Carbide nozzle Desulfurization silicon carbide nozzle models include one to four inches, special models can be customized according to customer requirements.
