脱硫设备在运行过程中,如果操作不当,不注意维护保养,经常出现脱硫塔内结垢、管道堵塞、机械密封损坏等各种问题,下面对脱硫设备的操作规程及维护保养注意事项做简要概述。
In the operation process of desulfurization equipment, if the operation is improper and maintenance is not paid attention to, there are often various problems such as scaling in the desulfurization tower, pipeline blockage, mechanical seal damage, etc. the following is a brief overview of the operation procedures and maintenance precautions of desulfurization equipment.
脱硫除尘装置在运行时需要对各个组件进行检查。
During the operation of desulfurization and dust removal device, each component needs to be inspected.
(1)检查脱硫装置,排污口要关闭,不可无水运行,不得漏风,以防无法闭缝运行。
(1) Check the desulfurization device, the drain outlet should be closed, no water running, no air leakage, in case it can not be closed operation.
(2)锅炉点火前把水池放满水,检查水泵是否正转,确认无误后,点火前开启水泵或自来水阀门,保证脱硫塔内有水,以防玻璃鳞片被烟气烧坏。
(2) Before the ignition of the boiler, fill the pool with water and check whether the water pump is running normally. After confirmation, open the water pump or tap water valve before ignition to ensure that there is water in the desulfurization tower, so as to prevent the glass flakes from being burned by the flue gas.
(3)正常运行时,保证脱硫装置的水位,才能达到好的脱硫效果。
(3) In normal operation, only by ensuring the water level of desulfurization device can good desulfurization effect be achieved.

(4)锅炉点火的同时,开启脱硫泵,防治脱水系统阻塞导致塔体的损坏。
(4) At the same time of boiler ignition, start desulfurization pump to prevent tower damage caused by dehydration system blockage.
(5)确保脱硫液PH值≥12时才能达到脱硫效果。
(5) The desulfurization effect can be achieved only when the pH value of desulfurization solution is more than or equal to 12.
(6)脱硫设备采用的循环水清洁度要在90%以上,否则会冲刷脱硫塔体,造成设备损坏。
(6) The cleanliness of circulating water used in desulfurization equipment should be more than 90%, otherwise it will wash the desulfurization tower and cause equipment damage.
(7)循环检查装置,观察流水情况。引风机不可带水,如引风机带水要立即降低除尘内水位。
(7) Circulation inspection device, observe the flow situation. The induced draft fan is not allowed to carry water. If the induced draft fan carries water, the water level in the dedusting chamber shall be reduced immediately.
停车时的维护保养
Maintenance when parking
(1)短时间减量或切气,脱硫系统不必停车,可根据时间长短适当减量,或保持原状。否则吸收再生液量减少后,一旦加量有时难以保证脱硫效果。
(1) The desulfurization system doesn't need to be shut down for short time reduction or gas cutting, but can be reduced appropriately according to the length of time or kept in the original state. Otherwise, once the amount of regeneration liquid is reduced, it is difficult to ensure the desulfurization effect.
(2)长时间停车,要关闭脱硫泵、冲洗泵出口阀门,停泵,关入口阀门,从泵导淋排液,切断上述泵的电源,并定期盘车,将溶液分别存放在三个槽内,并检查有无泄漏的地方。冬季要做好保温,少排导淋,防冻堵。
(2) Shut down the outlet valve of desulfurization pump and flushing pump for a long time, shut down the pump, close the inlet valve, drain the liquid from the pump, cut off the power supply of the above pump, turn the gear regularly, store the solution in three tanks respectively, and check for leakage. In winter, it is necessary to keep warm, discharge less water and prevent freezing.
