Disclosed are a process device and a process method of
liquid phase reaction desulfurization of
sulfur dioxide and
hydrogen sulfide. The process device includes a reactor and a separator. The reactorincludes a
tail gas absorption zone, a liquid
holding tank zone and a
reaction zone. The liquid
holding tank zone includes a separating plate, multiple gas lifting cylinders and a liquid down
pipe andcommunicates with the
tail gas absorption zone and the
reaction zone. The lower part of the
reaction zone is provided with at least two nozzles which are symmetrically distributed. The nozzles are obliquely fixed to the device wall of the reaction zone, and
nozzle heads extends obliquely upward to the inside of the reaction zone. A liquid collection tank is arranged on the upper part of the reaction zone. A
liquid phase extraction
pipe is arranged at the bottom of the liquid collection tank and communicates the liquid collection tank and the separator. The other end of the separator is connected to the top of the
tail gas absorption zone. Reaction gas is injected into the reactor through the nozzles to be violently mixing with a reaction solution in the reactor by using the process deviceof the invention, which greatly increases the
dissolution rate and
reaction rate of the gas in the reaction solution. The gas ejected from two symmetrical nozzles reacts in the reaction solution to generate
sulfur, and the continuously injected gas pushes the reaction solution entrained with the
sulfur to flow obliquely upward into the liquid collection tank. The solution in the reactor is alwaysin a flowing state so as to prevent the sulfur from depositing and scaling on the device wall and the bottom of the reactor to ensure safe, stable and long-term operation of the device.
