Mixed fluid stirring mechanism and tubular reactor

Abstract

The invention discloses a mixed fluid stirring mechanism and a tubular reactor. A main shaft is provided with a forward stirring structure and a reverse stirring structure, and paddle blades of the forward stirring structure and the reverse stirring structure are spirally arranged on the main shaft; the acting force generated by the forward stirring structure and the acting force generated by reverse stirring structure are opposite in direction. A relatively strong mixing effect can be achieved under the condition of low energy consumption, the problem that materials are conveyed in the reactor can be well solved, and the technical situation that the effect is not good during internal conveying of the reactor is made up for.

Description

technical field [0001] The invention relates to a mixing fluid stirring mechanism and a tubular reactor. Background technique [0002] Stirring equipment is often used in chemical reaction, material preparation and other fields. The current stirring equipment is basically a mechanical stirrer, and most of them use power equipment to drive the stirring rod (or stirring shaft) to rotate, so that the paddles set on the stirring rod move to achieve Stir. But, there is certain problem in the mode of this mechanical stirring. [0003] First of all, when the mechanical agitator on the market is used in a tubular reactor for chemical reaction, the raw material of the reactant needs to enter from one end of the tubular reactor. Therefore, it is required that the mechanical stirrer in the tubular reactor not only needs to have the function of stirring, but also needs to have the function of transporting the reactant raw materials from one end of the tubular reactor to the other end,...

But, there is certain problem in the mode of this mechanical stirring

[0003] First of all, when the mechanical agitator on the market is used in a tubular reactor for chemical reaction, the raw material of the reactant needs to enter from one end of the tubular reactor. Therefore, it is required that the mechanical stirrer in the tubular reactor not only needs to have the function of stirring, but also needs to have the function of transporting the reactant raw materials from one end of the tubular reactor to the other end, and the existing mechanical stirrer cannot meet the requirements. Material Transport Requirements in Tubular Reactors

[0004] In addition, the propeller blades or sheet-shaped blades of the existing mixing equipment will generate a strong circumferential speed when the shaft rotates at a high speed, which will lead to the separation of incompatible and different density mixing materials under the action of centrifugal force, reaching Not for the purpose of mixing different materials
