Description

Technical Field

[0001] The present invention relates to a gas-solid separation technology after heating and cracking of materials in a carbonization cracking furnace. Specifically, when the drum rotates, a drum scraper conveying device conveys the materials to the tail of the drum, and then the drum scraper conveying discharge collecting device collects the materials and sends them to a screw conveyor. The drum scraper conveys the gas-solid separation device, and the solid materials are conveyed to a drum external collecting device by the screw conveyor, and the cracked gas is conveyed to a gas collecting device under its own expansion pressure. Background Art

[0002] The present invention relates to the hazardous waste thermal cracking technology in the field of environmental protection. Most of the existing cracking furnaces first crack out gas, and then discharge the cracked powder solid materials after the furnace temperature cools down. Gas and solid materials cannot be discharged at the same time. A large amount of heat energy is wasted and the work efficiency is low. In order to save energy and improve production efficiency, a roller scraper conveying gas-solid separation device is developed. Summary of the invention

[0003] The object of the present invention is to provide a drum scraper conveying gas-solid separation device to achieve gas-solid separation after heating and cracking of materials in a carbonization cracking furnace.

[0012] The gas collecting steel pipe 5 of the screw conveyor device is installed in the packing box steel pipe 20. The gas collecting steel pipe 5 is concentric with the packing box steel pipe 20. The outer diameter of the gas collecting steel pipe 5 is 2 mm smaller than the inner diameter of the head.
