Description

Technical Field

[0001] The utility model relates to the technical field related to cracking, in particular to a gas and slag discharge anti-blocking device. 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] For example, waste rubber, plastic and rubber powder are all pyrolysis raw materials, which are generally processed in pyrolysis equipment. The slag produced by pyrolysis needs to be discharged through the slag outlet. In order to prevent the slag outlet from being blocked by large and incompletely pyrolyzed raw materials, a filter is generally set for filtering. However, most of the existing filters adopt an integrated structure, which is not convenient for maintenance and subsequent cleaning of blockages. Utility Model Content
