Problems solved by technology

The direct introduction of the air inlet pipe has a simple structure and smooth air outlet, which will not cause material accumulation and blockage, but the dispersion effect is poor; while the latter has a better dispersion effect, but due to its structural limitations, the gas in the ring pipe, polyhedron or There is a dead angle of air flow in the cylindrical air chamber, and the gas velocity distribution is uneven, s

Example Embodiment

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] See attached image 3 , attached Figure 4 , attached Figure 5 , which is a schematic diagram (longitudinal section) of the gas distribution chamber 5 with a hyperbolic draft tube and the gas flow patterns inside it. Its structure is: in the gas distribution chamber 5, there is a guide tube 6 with a hyperbolic longitudinal section. The gas outlet end of the guide cylinder 6 is open and arranged in the cavity of the gas distribution chamber 5, and the outer wall of the guide cylinder 6 and the inner wall of the shell 4 of the gas distribution chamber 5 form a volute-like case with a smooth surface and no dead ends. Shaped gas distribution space, a drain hole 9 is opened at the lowest point of the gas distribution chamber 5 . When working, the gas directly enters the guide tube 6 from the intake pipe 2, and then enters the v...

Abstract

The invention discloses a gas distributor for gas-liquid dispersion, which can efficiently disperse gas into liquid. The gas distributor comprises a gas distribution chamber, a gas outflow element arranged on a shell of the gas distribution chamber, and a guide flow cylinder which is arranged in the gas distribution chamber and communicated with a gas inlet pipe, wherein the gas distribution chamber is in the conventional shape or in an apple-shaped bottom structured spherical shape, oblate spheroid shape or flying saucer shape; a longitudinal section of the guide flow cylinder is in a hyperbolic shape or a cylindrical shape; and the gas outflow element is a spiral nozzle, a kerf conical nozzle, a straight pipe or conical pipe with a built-in spinning disk, a jet mixer or a micropore blind pipe. The gas distributor has the advantages of good dispersion effect, less possibility of blockage, high suitability for liquid materials and simple structure.

Description

technical field [0001] The invention relates to the field of gas-liquid reaction equipment, in particular to a gas distributor for efficiently dispersing gas in liquid. Background technique [0002] In many gas-liquid reactions where liquid is the continuous phase and gas is the dispersed phase, processes such as hydrogenation, chlorination, oxidation, and aerobic biological fermentation all involve introducing gas into the liquid through a gas dispersion device. At present, the commonly used gas dispersing devices are mostly directly introduced by the inlet pipe, or the inlet pipe is connected to the annular pipe with openings on the outer surface, polyhedral or cylindrical air chamber, and the gas is fed by the annular pipe, polyhedral or cylindrical air chamber. The pores on the chamber diffuse into the surrounding liquid. The direct introduction of the air inlet pipe has a simple structure and smooth air outlet, which will not cause material accumulation and blockage, b...
