TH9183B - Gas-liquid contact and de-sulfur from fluid gas by wet process - Google Patents

Abstract

The invention involves a gas-liquid contact device for effective introduction of gas into contact with a slurry solution, and a system for removing sulfur from flue gas by wet processes using this contact apparatus. Was incorporated into The system consists of a dosing tank with a slurry. Stirrer set fixed above the bottom of the tank To be rotated in a plane A number of gas supply hoses for supplying gas. To the area near the stirring stick Nozzle aimed at the area where the stirring stick is rotated Through or in the vicinity of the stirring rod And a number of liquid supply lines for supplying liquid to the nozzles

Claims (3)

1. The system for removing sulfur from flu gas by wet oxidizing process in tank consists of Adsorption tower with upper and lower sections The tank was supplied with a sorbent solution, a calcium-based sorbent. Located at the bottom of the adsorption tower Tank with bottom Circulating pump for pumping the sorbent slurry from the tank into the flue gas inlet available at the top of the adsorption tower to bring the slurry solution into contact with the flue gas. At least one set of stir sticks supported above the bottom of the tank. Stirring rod that rotates horizontally So that when the stirrer is spinning there is an area where the stirring bar is spun At least one air supply pipe to supply air for oxidation to a minimum, attached to most of the stirring rods, and at least one supply pipe with at least one nozzles most commonly flared. Straight to the area Which the stir rod spins through Therefore, when using it when the sludge accumulates on the stirring rod Sediment is removed This prevents the sludge from forming by passing the liquid through at least one fluid pipe to a minimum of a nozzle and spraying most of the liquid directly to the area where the stirring rod passes. Where the liquid dispenser is assembled The circle portion is relative to the area in which at least one stirring rod passes. And at least one nozzle consists of A number of nozzles that are installed periodically along the circular part of the supply pipe. 2. The system according to claim 1, where the circulating pump is composed of one side which is connected to the pipeline and the other side to the suction line. Where the pipelines are still connected to at least one of the fluid supply lines and to the fluid-gas passage. And the suction hose is also connected to at least one of the liquid supply lines and to the fluid-gas inlet. The suction hose is also connected to the bottom of the tank at a point higher than the height of the solid component deposition in the slurry solution. A number of control valves are used to force the solution down the pipeline by pumping it into either the flue gas inlet or the supply line. 3. The gas-liquid contact device consists of a tank to which the slurry is dispensed. The tank has a bottom At least one stirrer supported above the bottom of the drum, the stirrer can rotate horizontally so that when the stirrer is spinning, there is an area where the stirrer passes. At least one gas supply pipe For supplying gas to a minimum area, mainly attached to the stirrer. At least one liquid supply line with at least one nozzle most likely directed into the area where the stirrer is passed. So that while using When slurry accumulated on the stirrer was removed. And prevent slurry sludge from accumulating By supplying liquid through a liquid supply pipe to at least one nozzles, and most of the liquid is sprayed into an area where the stirrer rotates, where the liquid supply pipe consists of circular segments relative to the area, for example At least one stir stick spins through. And at least one nozzle consists of A number of nozzles that are installed periodically along the circular part of the supply pipe.
