Abstract
A nozzle of especial usefulness for injecting corrosive acids into geothermal brines and the like comprises a substantially straight, tubular injector body and a plurality of pairs of injection tubes connected such that the axial bores of the injection tubes are in fluid communication with the axial bore of the tubular injector body. The injection tubes of each pair extend in radial directions from, and in the same plane normal to, the axis of the tubular injector body. Moreover, all injection tubes are in one of two planes coincident to the axis of the tubular body and all pass through a plane parallel to the axis of the injector body.
Claims21
A nozzle useful for injecting a corrosive fluid into a fluid stream comprising:
- (a) a substantially straight tubular injector body having an axial bore therethrough;
- and
- (b) at least two pairs of substantially straight injection tubes having axial bores therethrough fluid tightly connected to the axial bore of the injector body, the injection tubes of each pair proceeding radially from, and in the same plane normal to, the axis of the injector body, and with each of the injection tubes lying in one of two planes containing the axis of the injector body, which injection tubes cut a third plane parallel to the axial bore of the injector body.
A mixing apparatus comprising in combination:
- (a) a cylindrical conduit for carrying a liquid;
- and
- (b) a nozzle within said conduit comprising:
- (1) a substantially straight tubular injector body mounted within said conduit and traversing an entire inner diameter of said conduit, said injector body having an axial bore, the axis of which is coincident with said diameter, the tubular injector body opening in at least one of its ends to a location exterior to said conduit;
- and
- (2) at least two pairs of substantially straight injection tubes having axial bores therethrough fluid-tightly connected to the axial bore of the injector body, with the injection tubes of each pair proceeding in a radial direction from, and in a plane normal to, the axis of the injector body, and with each of the injection tubes lying along one of two planes coincident with the axial bore of the injector body, which injection tubes cut a third plane parallel to the axial bore of the injector body.
A mixing apparatus comprising in combination:
- (a) a cylindrical conduit for carrying a liquid;
- and
- (b) a nozzle within the conduit comprising:
- (1) a substantially straight tubular injector body mounted within the conduit and traversing an entire inner diameter of the conduit, the injector body having an axial bore, the axis of which is coincident with the diameter, at least one end of the tubular injector body opening to a location exterior to the conduit;
- and
- (2) at least two pairs of substantially straight injection tubes of substantially equal length and having axial bores of substantially equal diameter therethrough, which axial bores of the injection tubes are fluid-tightly connected to the axial bore of the injector body, with the injection tubes of each pair proceeding in the radial direction from, and in a plane normal to, the axis of the injector body, cutting a plane parallel to the axial bore of the injector body, and terminating within the interior of the conduit, said injection tubes forming an angle as measured from a plane containing the axis of the conduit and the axis of the injector body between 25 and 60 degrees, with the closest distance between an end of an injection tube and the inside surface of the conduit being less than the smallest distance between the ends of any pair of injection tubes but not less than 75 percent of that smallest distance.
A mixing apparatus comprising:
- (a) a cylindrical conduit for carrying a liquid and
- (b) a nozzle within said conduit comprising:
- (1) a substantially straight tubular injector body having an axial bore therethrough;
- and
- (2) a plurality of injection tubes emanating from the injector body, the injection tubes being in fluid communication with the injector body and the ends of the injection tubes being arranged to lie in the same plane normal to the axis of said conduit.
