Description

Technical Field

[0001] The utility model relates to the technical field of tubular reactors, in particular to a detachable tubular reactor with dust removal. Background Art

[0002] Shell and tube reactor is also called tube bundle reactor. It is a fixed bed reactor composed of many very thin reaction tubes and catalysts in the tubes. The structure is similar to that of shell and tube heat exchanger, consisting of tube bundle, shell, and end caps. Flue gas, high-temperature steam, etc. are used outside the tubes to provide the heat required for the reaction, or molten salt heat transfer oil and water are used to remove the heat released by the reaction to maintain the reaction temperature. It is mostly used for strong exothermic reactions and strong endothermic reactions. For situations where the reaction proceeds very quickly, such as o-xylene oxidation reactor, ethylene oxidation reactor to ethylene oxide reactor, methanol oxidation reactor to formaldehyde reactor, etc., which refers to a reactor in which a chemical reaction is carried out in the tube of a shell and tube reactor. The heat carrier is used to remove or supply heat through the tube wall. The structure is similar to that of a shell and tube heat exchanger. The catalyst is evenly loaded in the tube, and the heat carrier is passed between the tubes. In order to enhance the heat transfer effect and continuously supply or take away the reaction heat, the heat carrier must be circulated. Different circulation methods are used according to different heat carriers, such as internal circulation and external circulation.
