Description

Technical Field

[0001] The utility model relates to the technical field of tubular reactors, in particular to a gas-liquid mixing rotary cutting tubular reactor. Background Art

[0002] Tubular reactors are a common type of chemical industrial equipment, widely used in petrochemical, metallurgy, fertilizer, pharmaceutical and other industries. Existing tubular reactors usually include horizontal tubular reactors, vertical tubular reactors, coil reactors, U-shaped tubular reactors and mechanically sealed dynamic tubular reactors.

[0003] The tubular reactors currently on the market have good heat transfer and mass transfer effects for liquid-liquid two-phase reactions, which improves production efficiency. The mass transfer and heat transfer effects can be enhanced by adding baffles, spoilers or rotating shafts inside the tubes. However, the tubular reactors on the market do not have an air intake device or a gas-liquid mixing device in their structures. Therefore, the tubular reactors for gas-liquid two-phase reactions still have problems such as inability to intake air, uneven gas dispersion and poor gas-liquid mixing effect. Therefore, in view of the above shortcomings, the utility model makes the following improvements. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a gas-liquid mixing rotary cutting tubular reactor, which solves the problems mentioned in the background technology.

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a gas-liquid mixing rotary cutting tubular reactor, comprising a reaction cylinder and connecting flanges fixedly arranged at both ends of the reaction cylinder, a rotating shaft is rotatably arranged inside the reaction cylinder, and a plurality of exhaust holes are provided on the surface of the rotating shaft, a gas dispersion column is provided on the surface of the exhaust hole, a front flange is fixedly arranged on the surface of the connecting flange on the left side by bolts, and an air inlet channel is provided in the middle of the front flange, a sealing plug is provided inside the air inlet channel, and an air inlet ferrule is provided at one end of the sealing plug.

[0006] Preferably, an inner magnetic steel component is disposed inside the front flange, and an outer magnetic steel component is disposed on the surface of the front flange.

[0007] Preferably, a rear flange is provided on the surface of the connecting flange on the right side by means of bolts, and a discharge sleeve is provided inside the rear flange.

[0008] Preferably, a heat exchange jacket is provided on the surface of the reaction cylinder, and a heat exchange cavity is formed between the inner wall of the heat exchange jacket and the surface of the reaction cylinder.

[0009] Preferably, a bracket is fixedly provided on the bottom surface of the connecting flange, and the bracket is narrow at the top and wide at the bottom, and the bracket is used to support the reaction cylinder.

[0010] Beneficial Effects

[0011] The utility model provides a gas-liquid mixed rotary cutting tube reactor. Compared with the prior art, it has the following beneficial effects:

[0012] (1) The gas-liquid mixing rotary cutting tube reactor solves the problem that the rotary cutting tube reactor cannot take in air by opening an air inlet channel in the rotary cutting tube reactor. At the same time, an exhaust hole of a gas dispersion column is added on the rotating shaft so that the gas can be fully dispersed. When the driving motor drives the rotating shaft, the material and the gas are continuously mixed during stirring, which not only solves the problem of air intake in the rotary cutting tube reactor, but also improves the effect of gas-liquid two-phase mixing and improves the reaction efficiency.

[0013] (2) The gas-liquid mixing rotary cutting tube reactor can transfer heat between the gas and liquid phases inside the reaction cylinder by setting a heat exchange jacket. BRIEF DESCRIPTION OF THE DRAWINGS
