Centrifugal type bubble atomizing injector for high-viscosity liquid

The invention discloses a centrifugal type bubble atomizing injector for high-viscosity liquid. The centrifugal type bubble atomizing injector comprises a nozzle plate, a base, a swirler, a gas-liquidmanifold, a liquid propellant joint, an auxiliary atomizing gas joint and gas propellant joints, wherein the nozzle plate is mounted on a lower end surface of the base; the swirler is coaxially fixedin a rectification cavity below a central body of the base; the gas-liquid manifold is coaxially arranged in an auxiliary atomizing gas channel above the central body of the base, and the top end isfixedly connected with the injector base through a blind flange; the liquid propellant joint is coaxially and fixedly mounted in a blind flange center hole located in the upper part of the gas-liquidmanifold; the auxiliary atomizing gas joint is fixedly mounted on the side wall of the base; and the gas propellant joints are uniformly distributed on the side wall of the base in the circumferentialdirection.
