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) 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.
(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) 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.
