In the desulfurization system, nozzle spray layer is mainly in the desulfurization tower, namely the sprinkler system, nozzle spray system become the final executor, nozzle working state determines the spray effect, so in the production process, we should conduct regular inspection and maintenance of the nozzle and. The inspection frequency of the nozzle should be arranged according to the use of the nozzle, and the nozzle maintenance plan should be determined according to the material of the nozzle and the nature of the bath.
Nozzle in the daily use, often appear problems are the following:
1, nozzle corrosion and wear nozzle with work time extension will gradually be trough liquid corrosion, or wear. When the nozzle is corroded or worn, the surface of the nozzle and the inner flow channel will gradually deform or increase, thus affecting the nozzle flow, spray pressure and spray shape. The nozzle is difficult to repair after being damaged by corrosion and abrasion. Only the new nozzle can be replaced.
Work for a long time, the 2 bond nozzle nozzle after bath or process because of various reasons for accelerating evaporation, edge and lateral nozzle can spray, spray and chemical because of accumulation, left a layer of solidified layer dry, resulting in clogging nozzle or flow, need to dredge maintenance personnel.
3, the nozzle nozzle nozzle in the long-term spray process, the bath liquid dirt and impurities will gradually accumulate in the nozzle mouth or internal flow pipeline. When the nozzle is blocked, the nozzle flow will gradually decrease, which will affect the working pressure, spray shape and liquid particle uniformity. Nozzle blockage can be carried out after repair dredge, obstruction more serious need to replace the new nozzle.
4, nozzle temperature damage nozzle long-term work in the temperature above the rated temperature environment, will cause damage due to high temperature, such as nozzle deformation or spray shape deformation. If the nozzle is subject to high temperature damage, it is proved that the material nozzle is not suitable for the working environment at that time, the nozzle should be planned to avoid unnecessary economic loss.
The installation problem of the nozzle, the nozzle 5 is not installed correctly for nozzle buried hidden troubles, such as nozzle installation or installation of the nozzle gasket deviated from the center, will tighten the excessive spraying effect when the nozzle cannot reach the expected goal. The installation of the nozzle can be solved by removing the two installation, if the installation has caused damage to the nozzle, a new nozzle should be replaced.
