Description

Technical Field

[0001] The utility model relates to the technical field related to cracking, in particular to a cracking furnace insulation shell. Background Art

[0002] The reaction process in which a substance decomposes when heated. Many inorganic and organic substances will undergo decomposition reactions when heated to a certain degree. In the past, the pyrolysis process did not involve catalysts, and other energy, such as reactions caused by ultraviolet radiation. At present, in order to improve the efficiency of pyrolysis, increase the yield of pyrolysis products, and prepare products that are not easy to prepare by conventional pyrolysis, more and more research is being done on adding catalysts to the pyrolysis process for catalytic pyrolysis. Some catalytic pyrolysis processes such as adding catalysts such as CaO and MgO to the pyrolysis of plastics have been used in industrial production.

[0003] Waste rubber, plastic and rubber powder are all pyrolysis raw materials and are generally processed in pyrolysis equipment.

[0004] The cracking equipment includes a furnace body, a heating base and an insulation shell. The existing insulation shell includes a metal outer shell, and then a layer of thin cotton is laid on the inner side of the metal shell, and then refractory material is poured. The overall mass of the insulation shell is large. After a period of use, the poured refractory material is prone to fall off, and it is also not conducive to transportation. Utility Model Content

[0005] The utility model aims to provide a cracking furnace insulation shell to solve the problems raised in the above background technology.

[0014] The thermal insulation shell of the cracking furnace as described above: a vent is formed on the side end of one of the half shells, and the vent can be blocked by a metal cap.

[0015] Compared with the prior art, the beneficial effects of the utility model are: in the utility model, the thermal insulation cotton is loaded on the inner side of the semi-shell, and then fixed by bolts and nuts, and then the curing glue is sprayed. After the curing glue hardens, a thermal insulation cotton protective layer is formed, which can effectively reduce the overall weight of the thermal insulation shell, facilitate transportation, and facilitate production, which can reduce the manufacturing cycle and save production costs.
