COMBINATION FEEDING AND MIXING DEVICE Russian patent published in 1999 - IPC

FIELD: introduction of the first fluid medium into the gaseous one and feeding through the flow passage towards the flow of the second fluid medium for mixing of fluid media. SUBSTANCE: the device has at least one pipe feeding the first fluid medium. The pipe has at least one feeding hole and a mixing insert located past the feeding hole relative to the direction of flow. The mixing insert uses mixing members, which are relatively small as compared with hydraulic diameter d_hydr. of the flow passage. The mixing members are arranged in rows parallel to each other in the plane directed at an angle to the direction of flow. The mixing members of each row are inclined relative to this plane in the same direction relative to one another and in the opposite direction relative to the members of each adjacent row. Taking into account cross-section area A and hydraulic diameter d_hydr. of the flow passage, provision is made for 0.05-10 feeding holes per square meter of the cross-section area of the flow passage. The distance between the feeding hole and mixing insert makes up a value between 0.05 and 3 d_hydr.. EFFECT: introduction of the first fluid medium into the second fluid medium at a low loss of head and low expenditures connected with the equipment and input into service, homogeneous distribution of the first fluid medium over the entire cross-section of the flow passage. 8 cl, 4 dwg
