The invention provides a desulfurizing tower emergency absorption device which is arranged on one side of a desulfurizing tower body and comprises an emergency solution storage tank, an emergency solution delivery pump, a first check valve, an emergency delivery pipeline, an emergency liquid return pipeline and a first pneumatic switch valve. When the desulfurization tower breaks down, data of an SO2 monitoring meter at the top of the tower is abnormal and reaches a chain set value, the emergency absorption device starts to work, the emergency solution in the emergency solution storage tank is conveyed into the desulfurization tower, emergency solution circulation is established, and flue gas desulfurization is achieved. A small amount of equipment is additionally arranged on the basis of an original desulfurization system, long-period stable purification and emission of the flue gas are achieved, the technological operation process is short, control parameters are simple, no complex operation process exists, and up-to-standard emission of the tail gas can be well achieved.
Description
technical field [0001] The invention belongs to the technical field of waste gas treatment, and in particular relates to an emergency absorbing device for a desulfurization tower and a use method thereof. Background technique [0002] Smelting flue gas acid production system generally adopts wet desulfurization to carry out advanced treatment of ring flue gas or acid production tail gas to meet the relevant national emission requirements. Wet desulfurization adopts a single absorption liquid, and through the countercurrent contact with the flue gas in the filler, the reaction removal of sulfur dioxide in the flue gas is realized. This requires high stability in the operation of the desulfurization equipment and facilities. The environmental indicators exceeded the standard in an instant, which ultimately affected the continuity of system production. [0003] How to improve the operation stability of the desulfurization system and ensure the long-term stable compliance of en...
