Abstract
The utility model discloses a gas and liquid mixing ejector of an airlift type aerobic fermentation tank, which consists of a nozzle, a mixing chamber, and a lotus type expansion sprayer. High-pressure air carrying fermentation liquor enters the mixing chamber through the nozzle to be evenly mixed; and then the fermentation liquor is ejected and stirred through the lotus type expansion sprayer so as to ensure that oxygen makes full contact with bacteria and the oxygen amount required by the fermentation liquor is satisfied. The gas and liquid mixing ejector of the airlift type aerobic fermentation tank has the advantages of replacing mechanical stirring by airflow stirring and being low in energy consumption, good in oxygen dissolution effect, high in fermentation speed and high in bioconversion rate.
Description
Technical field:
The utility model relates to air lift type aerobic fermentation tank Liqiud-gas mixing device, directly relates to air lift type aerobic fermentation tank gas-liquid mixed injector.
Technical background
China from last century end the biological fermentation that begins one's study produce L-lactic acid, realized suitability for industrialized production.The stirred-tank fermenter that is adopted, power consumption is big, and the dissolved oxygen weak effect influences growth and the metabolism of mikrobe.Research and develop that a kind of energy consumption is low, dissolved oxygen good, the fermentation equipment of fermentation high yield is very important.The air lift type aerobic fermentation tank of up-to-date research and development, its gordian technique are to seek a kind ofly can replace mechanical stirring, can reach the gas-liquid mixed injector of good dissolved oxygen effect again.
Summary of the invention:
The purpose of the utility model just provides a kind of air lift type aerobic fermentation tank gas-liquid mixed injector.Pressurized air gets into several gas-liquid mixed nozzles through several layers of loop draught pipe, and nozzle is the handstand cone, when high velocity air passes; Negative pressure is formed on the bottom, brings fermented liquid into mixing section, sprays through shower nozzle type expansion shower nozzle then and stirs fermented liquid; Reach fully contacting of oxygen and thalline; Satisfy the oxygen absorbed of thalline, both replaced mechanical stirring, reach good dissolved oxygen effect again.
The purpose of the utility model is to realize like this.Air lift type aerobic fermentation tank gas-liquid mixed injector mainly is made up of nozzle, mixing section, showerhead three parts, is connected on the annular compression blast main.
As the improvement project of the utility model, said nozzle is one section bending cone, and the pressurized air arm inserts from the crook by tangential direction.When high-speed gas passed through centrum, the bottom butt end formed negative pressuren zone for one section, and fermented liquid is inhaled into, and sprays into mixing section from thin end.
Further improvement project as the utility model: said mixing section is the round diameter of one section diameter greater than nozzle, and the gas step-down is slowed down and received the thin obstruction fold back of holding of upper end shower nozzle, and air mixes with fermented liquid.
As the another improvement project of the utility model, said seedpod of the lotus expansion shower nozzle is the thin down thick centrum that, and the upper surface is the arc surfaced stephanoporate steel plate, forms seedpod of the lotus shape, and gas liquid mixture sprays through the showerhead expansion and stirs fermented liquid, and oxygen fully contacts with thalline.
Description of drawings:
Accompanying drawing shows the structural representation of a kind of air lift type aerobic fermentation tank of the utility model gas-liquid mixed injector, below in conjunction with accompanying drawing the utility model is described further.
Embodiment:
Accompanying drawing is the structural representation of a kind of air lift type aerobic fermentation tank of the utility model gas-liquid mixed injector, has nozzle (1), mixing section (2), shower nozzle type expansion shower nozzle (3) three parts composition.
Said nozzle (1) is made up of nozzle (1) and segmental bronchus (4), and nozzle (1) is the cone of the band camber that is welded into of the stainless steel coiled sheet with 4mm thickness, camber R=0.5m; 21 ° of taperings; Butt diameter φ 200mm, diameter at smaller end footpath φ 50mm, segmental bronchus (4) is φ 76 * 3mm weldless steel tube; Insert nozzle (1) from the camber tangential direction and weld, segmental bronchus (4) lower end is connected with annular compression air main (5) with flange (6).
Said mixing section (2) is φ 108 * 3mm weldless steel tube straight tube, length 150mm, and the lower end undergauge is connected with nozzle (1) upper end with flange (6).
Said shower nozzle type expansion shower nozzle (3) is the cone that is welded into 4mm slab volume, and lower port diameter φ 100mm is connected with mixing section with flange (6), and back cut diameter is φ 200m, seals boring φ 10mm, pitch-row 30mm with the arc steel plate of evenly boring.
Principle of work:
Pressurized air (0.6MPa) gets into segmental bronchus (4) through annular compression air main (6), tangentially at a high speed through nozzle (1), forms negative pressuren zone in nozzle (1) lower end; Fermented liquid gets into negative pressuren zone, is brought into the mixing zone by high velocity air, and the high velocity air decompression is slowed down kinetic energy is passed to fermented liquid; Both mix, and shower nozzle type expansion shower nozzle evenly sprays from top, and air stirs fermented liquid once more; Fully contact with the thalline in the fermented liquid, supply thalline to absorb, satisfy the aerobic fermentation oxygen requirement.The characteristics of the utility model are: stir the replacement mechanical stirring with blast injection, save power consumption, air and fermented liquid mix, and dissolved oxygen is effective, satisfies the mikrobe oxygen requirement, improve fermenting speed and biological transformation ratio.
