An efficient regeneration desulphurization
tower comprises a desulphurization
tower 1, a
coal gas inlet 2, a
coal gas outlet 3, a pregnant solution outlet 4, a lean solution inlet, a regenerator 6, a lean solution outlet 7, a pregnant solution inlet 8, a solution recirculating pump 10, a
sulfur foam outlet 11, a lean solution groove 13, a high-pressure air inlet 14 and a gas-liquid
distributor 16, wherein the lean solution groove is formed in the
tower bottom at the lower end of the desulphurization tower, and the lean solution outlet and the
sulfur foam outlet are formed in the lower section; stuffing is mounted in the desulfuration section in the tower; the set of regenerator is mounted at the upper part of the lean solution groove; a solution circulating line is mounted outside the tower body; with the aid of one solution recirculating pump, the solution circulating inside and outside the tower body via the lean solution inlet, the pregnant solution outlet, the pregnant solution inlet and the lean solution outlet is realized. The desulphurization tower has an optimized structure, utilizes the large
diameter of the desulphurization tower, shortens the move distance of the solution, and reduces the loss of
system heat and various materials, also the
resistance force to 0.02-0.03 MPa. Moreover, the
energy consumption is reduced by 20-30 percent, and an efficient regenerator is adopted for oxidation regeneration of the pregnant solution and has the advantages of small size, strong regeneration capacity and stability in operation.
