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.
脫硫除塵裝置在運行時需要對各個組件進行檢查。
During the operation of desulfurization and dust removal device, each component needs to be inspected.
（1）檢查脫硫裝置，排汙口要關閉，不可無水運行，不得漏風，以防無法閉縫運行。
(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）正常運行時，保證脫硫裝置的水位，才能達到好的脫硫效果。
(3) In normal operation, only by ensuring the water level of desulfurization device can good desulfurization effect be achieved.
（4）鍋爐點火的同時，開啟脫硫泵，防治脫水係統阻塞導致塔體的損壞。
(4) At the same time of boiler ignition, start desulfurization pump to prevent tower damage caused by dehydration system blockage.
（5）確保脫硫液PH值≥12時才能達到脫硫效果。
(5) The desulfurization effect can be achieved only when the pH value of desulfurization solution is more than or equal to 12.
（6）脫硫設備采用的循環水清潔度要在90%以上，否則會衝刷脫硫塔體，造成設備損壞。
(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）循環檢查裝置，觀察流水情況。引風機不可帶水，如引風機帶水要立即降低除塵內水位。
(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.
