Abstract

The invention relates to a testing device of the desulphurization efficiency and a testing method thereof. The testing device comprises a buffering bottle, an SO2 absorbing bottle I, an absorbing system A and an absorbing system B. The testing method comprises the following steps of: adding alkaline solution with same volume V into all the SO2 absorbing bottles, introducing the same amount of SO2 gas to enable the absorbing system A to absorb and test PH values of testing liquid in all the SO2 absorbing bottles, and calculating the molar weight of the SO2 absorbed by the absorbing system A; and then introducing the same amount of SO2 gas to enable the absorbing system B to absorb and test PH values of testing liquid in all the SO2 absorbing bottles, calculating the molar weight of SO2 absorbed by the absorbing system B, and calculating the desulfurization efficiency. The testing device has the advantages that the structure is simple, and the operation is easy; the two absorbing systems are utilized for respectively absorbing the SO2 gas, the total amount of the absorbed SO2 and the amount of SO2 absorbed by limestone slurry are measured by a PH meter, the desulphurization efficiency of the limestone slurry is tested, the experimental data is accurate and reliable, the experimental steps are simplified, and the experimental cost is lowered.

Description

technical field [0001] The invention relates to the field of exhaust gas purification, in particular to a desulfurization efficiency test device and a test method thereof. Background technique [0002] At present, in some experiments, it is often necessary to test the desulfurization efficiency of limestone slurry in the desulfurization system. The common method is to use a flue gas analyzer to measure SO 2 to calculate the desulfurization efficiency of the desulfurization system; or use limestone slurry bottles and multiple bubbling absorption bottles to absorb SO 2 , and then use chemical analysis to measure the sulfur ions in the bubbling absorption bottle, and then calculate the absorbed SO 2 Molar mass and total SO introduced 2 Molarity. [0003] If the method of flue gas analyzer measurement is used, it is necessary to ensure a long SO 2 In order to ensure the sufficient amount of flue gas measured by the flue gas analyzer at the inlet and outlet of the desulfuriza...
