Description

Technical Field

[0001] The utility model relates to the technical field of condensing devices, in particular to a direct cooling type cracking equipment condensing device. Background Art

[0002] Waste tires, waste rubber and waste plastics are transported into the cracking furnace through the feeder. The cracking furnace can heat the materials to be processed so that they can be cracked. The materials are heated in the cracking furnace and converted into mixed hydrocarbon vapor. Then, the useful substances in the mixed hydrocarbon vapor are recycled and reused by means of condensation. During condensation, the prior art usually adopts the method of passing the cracked materials (i.e. the mixed hydrocarbon vapor mentioned above) into the condensation pipeline. The entire condensation pipeline, except for the air inlet and the air outlet, is immersed in the condensation box containing the condensation medium (such as water). In order to ensure the condensation effect, the condensation medium can also be designed to be able to circulate.

[0003] The solids and liquids deposited at the bottom of the condensation pipe of the existing condensation device after condensation are difficult to clean. At the same time, most of the existing condensers are integrated, which is very troublesome to replace and repair. Utility Model Content
