VACUUM OIL PRODUCTION PUMP REACTOR WITH HYDRAULIC SEAL FOR CATALYTIC REFORMING REACTION OF PRETREATED PULP-LIKE WASTES AND DEVICE TO THIS END Russian patent published in 2014 - IPC C10G1/08 C10G1/10 B09B3/00 

FIELD: engines and pumps.

SUBSTANCE: invention relates to vacuum oil production reactor comprises shaft with bearings and housing with mechanical seal to prevent shaft oil leaks and hydraulic seal arranged on drive side between mechanical seals (1, 3) and bearings (10). Hydraulic seal comprises oil chamber and housing pressure side chamber (12) communicated with pressure line (5) via feed line (13) and lined (15) with shutoff valve arranged at chamber bottom pressure side (12) equipped with shutoff valve (16) for removal of particles contained in oil. Oil chamber (4) is controlled by safety valve (9) at overpressure of 0.05 bar. Chamber pressure side pressure (12) is controlled by shutoff valve. Note here that said pressure (12) set to exceed oil chamber overpressure (4). Besides, invention covers to sealing of said reactor. Additionally, this method consists in application hydraulic seal in combination with mechanical seal. Note also that mechanical seal comprises oil chamber, its pressure being set to ensure sufficient shaft bearings lubing while chamber pressure in direction of seal is kept at minimum level.

EFFECT: perfected design, reliable and efficient process.
