step three: the gas after secondary desulfurization enters a demisting cavity (5) and then meets a splitter plate A (61) for blocking, a part of water vapor is adsorbed on the splitter plate A (61), gaps among the splitter plate A (61), the splitter plate B (62) and the splitter plate C (63) are S-shaped, most of water vapor is adsorbed on three splitter plates after the gas is bent, when the remaining small part of water vapor passes through an adsorption filter layer (64), a heating sheet (82) is used for heating, so that the water vapor is evaporated when the water vapor passes through, and the demisted gas enters a detection device (7);
step four: when the demisted gas enters the sealed outer box (71), the sulfur detector (72) detects the gas, when the sulfur content of the gas is qualified, the electromagnetic valve on the discharge pipe (74) is opened to discharge the gas, if the detection is unqualified, the electromagnetic valve on the discharge pipe (74) is closed, the electromagnetic valves arranged on the return pipes (73) are opened to discharge the gas into the water tank (2) for desulfurization again.
9. The demisting method for the wet desulphurization demisting device of the wet electric dust collector as claimed in claim 8, wherein for the second step, the three spray pipes (42) are distributed in an S shape, and the installation baffle (41) is semicircular, so as to increase the time for the gas to pass through the desulphurization chamber (3) and ensure that the limestone water sprayed from the spray pipes (42) is fully contacted with the gas.
