REACTION DEVICE FOR SUSPENSION AND GAS

PURPOSE: To enhance the reaction efficiency and thereby rationalize systems such as chemical reaction and cleaning by discharging the upward flow of suspension branched into upward and downward flows into the bottom of a tank through an upward circulation pathway to be a quietly turning flow, and injecting a gap into a high pressure region to allow a gas-liquid contact to take place. CONSTITUTION: A suspension sucked from the center bottom of a reaction tank 1 is branched into an upward and downward flows using a branching device 4, by a pump 3, through a baffle board 2 at the center bottom of the tank 1, and the suspension is discharged from the lower part of the tank 1 through a branched upward circulation pathway to form a vertically turbulence- free turning flow. Besides, a gas is injected into a high pressure region from a pump circulation pathway 3 to a discharge through an injection orifice 5. Then, the gas is dissolved effectively and the suspension and the gas react with each other effectively in the turning flow. After that, bubbles used are afloat at the top of the tank 1 and flow out of an overflow orifice 6. The above system is applicable to sewage treatment facilities, water cleaning and the activation of an aquarium for fishery.
