Description

Technical Field

[0002] With the development of economy and the continuous improvement of people's living standards, the amount of domestic waste is increasing. At present, the main methods of domestic waste treatment are landfill and incineration. Landfill takes up a lot of land resources, and the proportion of landfill is decreasing as land resources are precious. Due to the poor classification of domestic waste, the calorific value of waste is too low when used for incineration power generation, the power generation efficiency is low, and secondary pollution is generated. Incineration cannot effectively treat waste.

[0003] The method for treating carbon black by pyrolysis in a domestic garbage furnace has little environmental pollution during the pyrolysis process, and the oil, combustible gas and solid after pyrolysis are all recyclable products. The oil and combustible gas after pyrolysis can be used as fuel, and the solid product is activated carbon or building materials. However, due to the immature rotary kiln technology used in pyrolysis and the defects of the pyrolysis equipment, the expected pyrolysis effect cannot be achieved, and the garbage treatment cannot be continuously and stably operated. The various equipment currently known can only be used for single-furnace treatment. After treatment, the furnace needs to be stopped to clean the slag, and there are often accidents in the furnace where the clots are hardened to the inner wall, requiring workers to enter the interior for cleaning after the shutdown. In addition, the furnace needs to be cooled down every time it is stopped, which causes energy loss and low efficiency of the pyrolysis furnace. Summary of the invention

During the rotation of the rotary cracking kiln, the sheet sealing structure contacts and rubs against the cylinder of the rotary cracking kiln.

The cooling coil is mainly arranged near the sealing strip of the fixed structure at the end of the rotary kiln. Both ends of the cooling coil are respectively connected to the cooling water inlet pipe and the cooling water outlet pipe.

From top to bottom, the solid-gas separator sealing liquid level, the solid-gas separator sealing liquid level oil layer, and the solid-gas separator sealing liquid level water layer are arranged in sequence inside the solid-gas separator shell. After the cracking gas and the cracking slag enter the solid-gas separator, the cracking slag falls into the solid-gas separator ash hopper and enters the slag scavenger after passing through the solid-gas separator sealing liquid level. The slag scavenger is used to send the cracking slag out of the equipment.

[0013] As a preferred embodiment, the solid-gas separator is further provided with a chute hanger, which is used to fix the grinding ball chute so that the grinding ball chute does not rotate with the rotating cracking kiln. The solid-gas separator is provided with a solid discharge port, a combustible gas discharge port, and a cracking gas discharge port;

[0014] The solid discharge port is used to discharge the cracked solids into the slag remover. The slag remover is equipped with water or oil to seal the flue gas to prevent gas leakage.

The grinding ball chute 21 does not rotate with the rotary cracking kiln 12. The two ends of the grinding ball chute 21 are respectively supported on the fixed structure 9 at the end of the rotary kiln and the solid-gas separator 24.

When the rotary cracking kiln 12 rotates, the grinding balls 20 gathered at the bottom of the rotary cracking kiln 12 and the grinding ball blocking plate 22 follow the rotation and rise, and then fall onto the grinding ball chute 21; the fallen grinding balls 20 roll toward the inlet end of the rotary cracking kiln 12; the grinding ball chute 21 is evenly arranged with holes from small to large laterally from the outlet end to the inlet end, and the hole size corresponds to the size of the corresponding grinding ball 20, so that the grinding balls 20 of different specifications and sizes can slide out of the grinding ball chute 21 at different positions and heights, thereby smashing and damaging the cracked products in the rotary cracking kiln 12. Grinding balls 20 of different specifications and sizes are placed in the rotary cracking kiln 12. The rotation of the rotary pyrolysis kiln 12 drives the grinding balls 20 to roll or fall, thereby crushing the pyrolysis products and the pyrolysis carbon glue.
