Systems and methods for bearing housings are disclosed. A labyrinth seal bearing housing includes: a first seal element that is structured and arranged to be connected to a wall of a mixing vessel; a second seal element that is structured and arranged to be connected to a rotatable shaft; and a bearing support that is structured and arranged to be connected to the first seal element. The second seal element is configured to rotate relative to the first seal element and the bearing support. The first seal element and the second seal element are structured and arranged to create a tortuous flow path between an exterior and an interior of the mixing vessel.

A reactor apparatus is provided having a reaction chamber; a compartmentalizing apparatus including a plurality of compartments, each compartment being open at a top end and bottom end, the compartmentalizing apparatus being disposed within the reaction chamber; and an inlet disposed at an area of the reactor and in fluid communication between the reaction chamber and a feed source. Also provided is a reactor apparatus having an assembly having a reaction chamber; at least one agitator assembly configured to generate mixing within the reaction chamber, the agitator assembly including: a shaft partially lined or coated with a fluoropolymer or other non-metallic corrosion-resistant material, and an impeller lined or coated with the fluoropolymer or other non-metallic corrosion-resistant material; and an inlet disposed at an area of the reactor and in fluid communication between the reaction chamber and a feed source. The provided reactor apparatus can be utilized in hydrofluorination processes.
摘要:
A sealing bushing for a member rotatable about a vertical axis and extending through a wall of a housing, which bushing comprises a sleeve fixedly connected to the wall of the housing and a sleeve fixedly connected to the shaft of the rotatable member. The last-named sleeve is concentrically received in the first-named sleeve. The bushing further comprises means for maintaining a sealing liquid in the clearance between the sleeves, which clearance opens at its top into a space in which a movable member is mounted that, when urged upwards by the sealing liquid, seals a clearance between the sleeve connected to the shaft and the housing.

Disclosed is a stirring device (D) including a screw shaft (1) driven by a drive unit, the screw shaft (1) being guided with respect to a body by way of a bearing, the stirring device furthermore including a seal (8) rigidly secured to the body and in contact with the ball joint (7) so as to ensure sealing with respect to the fluid to be stirred. The seal (8) is mounted on a seal holder (9), the seal holder (9) including a contact region (10) and being able to take up two positions, a first, operating position in which the seal (8) is in contact with the ball joint (7), and a second, maintenance position in which the contact region (10) is in contact with the ball joint (7).
