Determination and Size of Gap Fins@Flushing Nozzles for Glass Steel
---Lianqiang Flake Mastic @
Description: The distance between the FRP mist eliminator nozzles is determined according to the size of the desulfurization tower and the spray angle of the nozzle, ensuring that the entire demister can be covered by water mist. The 3.2-meter-diameter tower uses a baffle demister with excellent effect. The 120-degree spiral nozzle is 900-1000 meters away from the demisting panel.
Determination and Size of Gap Flushing Nozzles for FRP Demister
FRP mist eliminators are usually made up of two parts of glass fiber reinforced demister body and flushing system. The function of rinsing system is to periodically flush the droplets and dust trapped by FRP demister to keep the surface of blades clean (in some cases, to maintain The moist surface of the blade) prevents scaling of the blade and maintains normal operation of the system. The flushing nozzle is the most important executing component in the flushing system. The flushing nozzles at home and abroad generally use solid cone nozzles. After the flushing water is sprayed from the nozzles, the shape is a solid cone.

According to the size of the desulfurization tower and the nozzle spray angle, it is ensured that the entire demister can be covered with water mist. The 3.2-meter-diameter tower uses a baffle demister with excellent effect. The 120-degree spiral nozzle is 900-1000 meters away from the demisting panel.
The flushing water pressure is too low, the flushing effect is poor, and the fouling phenomenon is easy to occur. If the flushing water pressure is too high, the flue gas is liable to increase, and the service life of the corrugated board is reduced. Rinse water pressure should be determined based on the characteristics of the flushing nozzle and the distance between the flushing nozzle and the FRP demister (usually 0.4-0.8m). Under normal circumstances, the flushing pressure of the first demister should be higher than the second demister, and the flushing pressure of the FRP eliminator on the windward side is higher than the flushing pressure on the downwind side. Sometimes, in order to save costs and simplify the control system, the same basic flushing water pressure (≥0.2 MPa) is often selected.
Rinse coverage refers to the degree of coverage of the FRP flusher on the FRP section. According to different working conditions, the flush coverage is generally selected from 100% to 300%. It must be ensured that there is absolutely no flush corner left, otherwise it will easily cause fouling. Under general conditions, the peripheral flushing force of the spray projection surface of the nozzle is weak, and it should be considered that there is a certain degree of flushing overlap to ensure a good flushing effect.
