Embodiment Construction
[0027] Such as Figure 1-2 As shown, an on-line detection device for the sealing of a rotary retort furnace of the present invention includes a seal, including a rotating seal ring 8 fixedly connected to the rotating end and a fixed seal ring 7 fixedly connected to the fixed connecting ring. The sealing ring 7 and the rotating sealing ring 8 are attached together. In this embodiment, the side of the fixed sealing ring 7 and the rotating sealing ring 8 is the frictional environment surface, and the corresponding rotating sealing ring 8 is attached to the fixed sealing ring 7. One side is the frictional environment side. The frictional environment surfaces of the fixed sealing ring 7 and the rotating sealing ring 8 are cast with gray cast iron HT100, and after processing, the coincidence degree of the two planes is ensured.
[0028] An annular groove is provided on the side of the stationary seal ring 7 that is attached to the rotary seal ring 8, so that when the stationary sea...

The invention discloses an online detection device and method for leakproofness of a rotation dry distillation furnace. The device comprises a fixed seal ring and a rotating seal ring which are attached. An annular groove is formed in one side, attached to the rotating seal ring, of the fixed seal ring, and therefore an annular water vapor cavity is formed when the fixed seal ring and the rotating seal ring are attached. The device further comprises a water vapor guide-in pipe and a condensate guide-out pipe. One end of the water vapor guide-in pipe and one end of the condensate guide-out pipe are communicated with the water vapor cavity. The water vapor guide-in pipe and the condensate guide-out pipe are each provided with a regulation gate valve, a flow meter and a flow and pressure monitoring device. According to the device, the water vapor guide-in pipe and the condensate guide-out pipe are each provided with the corresponding regulation gate valve and the corresponding flow meter, and once the end face of the rotation dry distillation furnace is deformed due to installation errors, abrasion and thermal stress concentration and sealing of the end face are not tight enough, the water vapor flow and the pressure instantly change, the system instantly gives out an alarm, real-time detection is achieved, related measures are taken, and the sealing effect of the system is ensured.
Description
technical field [0001] The invention relates to an online detection device and a detection method for the sealing performance of 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 rotary fur...
