FIELD: process engineering. ^ SUBSTANCE: invention relates to sprinklers that mix fluid and gas in small-drop spray cone, e.g. oil and steam in catalytic cracking plant. Proposed sprinkler features various configurations to prevent erosion of its outlet. Said erosion may result from contact with catalyst or any other predetermined substances. Sprinkler comprises ceramic outlet with, at least, one outlet aperture, and metal inlet for, at least, one inlet fluid pipeline. Besides, sprinkler comprises metal joint to joint ceramic outlet to metal inlet to preset fit at ceramic outlet. Note here that invention allows preventing loose joint there between resulting from different thermal expansion and contraction. ^ EFFECT: optimised design. ^ 30 cl, 21 dwg |
