Title (EN) UREA SOLUTION SPRAY NOZZLE
(FR) BUSE D'INJECTION D'URÉE-EAU
(JA) 尿素水噴射ノズル
Abstract:
(EN) The purpose of the invention is to provide a urea solution spray nozzle that can suppress deposition and growth of urea in the urea solution spray nozzle. In the urea solution spray nozzle (1) pertaining to the present embodiment, urea solution flow channels (2c)·(3c) and gas flow channels (2d)·(4e) are configured, and a urea solution and a gas are mixed and sprayed from a spray port (4f); a slit (5d) as a side-surface discharge port being configured so that the gas is discharged in the same direction as the urea solution spray direction along surfaces (4c)·(4d) of the urea solution spray nozzle (1), and a water-repellent coating layer (4h) being formed on the surfaces (4c)·(4d) of the urea solution spray nozzle (1).
(FR) L'invention a pour objectif de fournir une buse d'injection d'urée-eau permettant d'empêcher la précipitation ou la croissance d'une urée dans sa partie interne. Dans la buse d'injection d'urée-eau (1) de l'invention, sont configurés des trajets d'écoulement urée-eau (2c, 3c) et des trajets d'écoulement de gaz (2d, 4e), et une urée-eau et un gaz sont mélangés et injectés depuis un orifice d'injection (4f). Une fente (5d) constituant un orifice de décharge de face latérale, est configurée suivant des surfaces (4c, 4d) de la buse d'injection d'urée-eau (1), de sorte que le gaz est déchargé dans la même direction que la direction d'injection d'urée eau. Enfin, une couche de revêtement hydrofuge (4h) est formée sur les surfaces (4c, 4d) de la buse d'injection d'urée-eau (1).
(JA) 尿素水噴射ノズルにおける尿素の析出および成長を抑制することができる尿素水噴射ノズルの提供を目的とする。本実施形態に係る尿素水噴射ノズル(1)は、尿素水流路(2c)・(3c)と気体流路(2d)・(4e)とが構成され、尿素水と気体とが混合されて噴射口(4f)から噴射される尿素水噴射ノズル(1)であって、尿素水噴射ノズル(1)の表面(4c)・(4d)に沿って尿素水の噴射方向と同一の方向に気体が吐出されるように側面吐出口であるスリット(5d)が構成され、尿素水噴射ノズル(1)の表面(4c)・(4d)に撥水コーティング層(4h)が形成されたものである。
