Abstract
Mélangeur statique destiné au traitement d'une matière par un fluide injecté. Il comprend plusieurs dispositifs de mélange. Un injecteur, intégré au 1**er de ceux-ci pour distribuer un fluide sur toute la surface de ce dispositif, comporte un tuyau fixé au 1**er dispositif et percé de chaque côté d'orifices obliques correspondant aux surfaces supérieure et inférieure dudit dispositif pour que le fluide injecté dans le tuyau en soit expulsé et vienne en contact, sur les 2 côtés du dispositif, avec la matière ou le liquide que contient l'appareil. Application : blanchiment de la pâte à papier par du chlore gazeux injecté dans cette pâte.Static mixer intended for the treatment of a material by an injected fluid. It includes several mixing devices. An injector, integrated into the 1 ** st of these to distribute a fluid over the entire surface of this device, comprises a pipe fixed to the 1 ** st device and pierced on each side with oblique orifices corresponding to the upper and lower surfaces of said device so that the fluid injected into the pipe is expelled and comes into contact, on the 2 sides of the device, with the material or the liquid contained in the device. Application: bleaching of the paper pulp with gaseous chlorine injected into this pulp.
