Abstract

A sealing device with a universal angle compensating tube is arranged between a screw feeder and a hollow shaft neck of a rotary gas retort. The sealing device with the universal angle compensating tube comprises a universal angle compensating tube fixing flange arranged on the screw feeder, the universal angle compensating tube which is connected with the universal angle compensating tube fixing flange in flange sealing mode, a floating sealing pipe connected with an universal angle compensating tube flange, and a hollow shaft neck optical flange, wherein the hollow shaft neck optical flange is arranged on the hollow shaft neck of the rotary gas retort, is connected with the floating sealing pipe in sealing mode, and is capable of rotating relative to the floating sealing pipe. The universal angle compensating tube comprises a left side straight pipe section, a middle metal ripple pipe section and a right side straight pipe section. One end of the floating sealing pipe is provided with a flange plate which is used for connecting the universal angle compensating tube, and the other end of the floating sealing pipe is provided with a flange plate used for matching with the hollow shaft neck optical flange. By means of the sealing device with the universal angle compensating tube, tight seal between the rotary gas retort and the screw feeder is achieved, vibration and noise in an equipment operation are reduced, reliability and safety of the technology of coal low temperature pyrolysis are enhanced.

Description

technical field [0001] The invention relates to a sealing device installed between a rotary dry distillation furnace and a screw feeder. Background technique [0002] At present, with the promulgation of the "12th Five-Year Plan for the Coal Industry", the state requires that in the next few years, we will vigorously develop clean coal technology and strengthen the research and development and demonstration of lignite upgrading technology. Lignite low-temperature pyrolysis technology has attracted increasing attention in China because of its high yield of tar and gas, and solid high-carbon semi-coke, and corresponding experiments and promotions have been carried out in major lignite producing areas such as Inner Mongolia and Northeast China. [0003] In the low-temperature pyrolysis technology of lignite, the rotary carbonization furnace is the core equipment, and the outlet of the screw feeder is inserted into the furnace cavity of the rotary carbonization furnace. The rot...
