UNIT OF COKE DRUM AND COKE-CRUSHING PLANT FOR USE IN CLOSED GAS-PROOF SYSTEM FOR PRODUCTION OF MARKETABLE PIECES OF OIL COKE FROM CURED OIL COKE IN COKE DRUM INSTALLATION, AS WELL AS CLOSED GAS-PROOF SYSTEM CONTAINING SUCH UNIT

摘要

FIELD: machine building.;SUBSTANCE: invention relates to assembly of coke drum and coke-crushing plant for production of petroleum coke pieces, as well as to closed gas-proof system containing this unit. Unit (2) includes coke drum unit (4) containing hardened oil coke, coke-crushing plant (12) for crushing petroleum coke, located under coke drum unit (4). Lower pipe (10) connected to coking crushing unit (12), having upper end section. Upper pipe (8) connected to lower end of coke drum unit (4), having lower end section with smaller diameter. At that, lower end section of upper pipe (8) enters upper end section of lower pipe (10), as well as at least one peripheral sealing element providing a gas-tight seal between upper pipe (8) and lower pipe (10) and allowing axial and radial movement of upper pipe (8) relative to lower pipe (10).;EFFECT: technical result consists in improvement of safety of operation, as well as in exclusion of damage.;13 cl, 4 dwg
