CLOSED PIPELINE FLOW STRAIGHTENER

摘要

FIELD: process engineering.SUBSTANCE: invention relates to device for flow straightening (straightening of flow rate profile) in closed pipelines. Closed pipeline for UV-irradiation comprises channel (1) accommodating UV-irradiator (6). Upstream of said UV-irradiator (6) arranged is flow straightener (10). The latter comprises at least one inner first guide element (11) and at least one outer second guide element (13). The latter is located at some distance from outer wall and composed of the pipe. Upstream open flow area of said pipe is smaller that downstream open flow area.EFFECT: perfected uniformity of the flow in UV reactor to allow approx equal UV radiation doses.16 cl, 21 dwg
