Abstract

The invention provides a tubular reactor. The reactor comprises a reaction tube (2) capable of containing reaction fluid which passes through and reacts in the tube, the reaction tube (2) comprises aplurality of spiral tubes (21), the spiral tubes (21) spirally wind, or the spiral tubes (21) are arranged in a spiral array, and the spiral tubes (21) are sequentially connected in series to form reaction tubes. According to the reactor, the residence time of the reaction fluid is greatly increased, the problems in the prior art that a pipeline needs to be processed too long and cannot be easilyachieved in the industry when the reaction rate is low are solved, the floor space is effectively reduced, the reactor is well achieved, the heat exchange effect is improved, the flow length of the fluid is increased, the reaction residence time is ensured, and the reactor is suitable for reactions with large residence time.

Description

technical field [0001] The invention belongs to the technical fields of chemical engineering and medical machinery, and in particular relates to a tubular reactor. Background technique [0002] Tubular reactor is a continuously operating reactor with a tubular shape and a large length-to-diameter ratio. Such reactors can be very long, for example, reactor tubes for propylene dimerization can be measured in kilometers. The structure of the reactor can be a single tube or a multi-tube parallel connection; it can be an empty tube, such as a tube cracking furnace, or a filled tube filled with granular catalysts in the tube for heterogeneous catalytic reactions. [0003] Traditional tubular reactors have the following disadvantages: [0004] 1) It occupies a large area and is fixed by brackets; [0005] 2) When the reaction rate is very low, the required pipeline is too long, which is difficult to realize industrially; [0006] 3) Heating and cooling need to set up casing or ...
