<p>PURPOSE:To prevent the adhesion of deposits to the outer circumference of cavity by providing a plurality of inclined grooves at an equal interval on the outer circumference of a dispersion apparatus to divide and disturb the stagnated region of a fluid, said inclined grooves running toward outer diameter part of a downstream side from the inner diameter part of an opposing side to a liquid exhaust nozzle. CONSTITUTION:A plurality of inclined grooves 3 is provided at an equal interval on the outer circumference of a dispersion apparatus, said inclined grooves running toward the outer diameter part of a downstream side from the inner diameter part of an opposing side to a liquid exhaust nozzle. The inclined grooves 3 from the outer circumference of a cylindrical cavity. Preferably, a point where the back end part of the grooves 3 meets the outer diameter of the cavity, also meets the back end part of the cylindrical cavity. Thus, when used in the combination with the liquid exhaust nozzle N, the adhesion of the deposits of the outer circumference of the cavity can be protected by dividing and disturbing the stagnated region with a zone dispersion stream having a dispersion angle alpha2 due to the grooves 3, said stagnated region being formed by the cylindrical dispersion stream Sc having a dispersion angle alpha1, due to the outer diameter d, of the cavity.</p> |
