Dynamic and static combined part sealing device of rotary dry distillation furnace and rotary dry distillation furnace

Abstract

The invention discloses a dynamic and static combined part sealing device of a rotary dry distillation furnace and the rotary dry distillation furnace. The sealing device comprises a fixed end, a rotating end, a support spring and a soft connecting piece, wherein the fixed end comprises a fixed support piece and a fixed connecting ring connected through the support spring and the soft connecting piece; and the support spring is provided with an adjusting ring for adjusting the pre-tightening force between the fixed connecting ring and the support spring. The sealing device further comprises a rotary sealing ring and a fixed sealing ring; the fixed sealing ring and the rotary sealing ring are arranged in a manner of fitting each other; and one side, fitting with the rotary sealing ring, of the fixed sealing ring is provided with an annular groove to form an annular water vapor cavity to be fully filled with water vapor for sealing and preventing smoke inside and outside the rotary dry distillation furnace from channeling. The sealing device uses the adjusting nut for adjusting the plane contact ratio of a fixed end friction surface and a rotary end friction surface, and thus guarantees a sealing effect of the rotary dry distillation furnace. The sealing device is provided with the water vapor cavity for further reinforcing the sealing effect in an operation state and a heat state.

Description

technical field [0001] The invention relates to a sealing device for a dynamic and static joint of a rotary carbonization furnace and a rotary carbonization furnace, belonging to the technical field of rotary equipment sealing. Background technique [0002] my country is relatively rich in coal resources, but low-rank coal with low utilization value occupies a considerable proportion. At present, the technologies for developing low-rank coal into high-rank coal are as follows: Circulating fluidized bed solid heat carrier rapid coal upgrading Technology, gas heat carrier rapid coal upgrading technology, belt coal dry distillation upgrading technology, moving bed coal upgrading technology, rotary furnace coal upgrading technology. Through years of tests and verifications, the rotary furnace coal upgrading technology is gradually becoming the mainstream technology with its outstanding technical advantages. [0003] Rotary carbonization furnace is an important equipment in rotar...
