Abstract

The utility model discloses a high-efficiency air distributor which comprises an outer cylinder body and an inner cylinder body which are coaxially arranged, wherein the upper end surfaces and lower end surfaces of the outer cylinder body and the inner cylinder body are covered by an upper cover plate and a lower cover plate; a compressed air depressurization cavity is formed in the inner cylinder body; a dissolved oxygen exchange cavity is formed between the outer wall of the inner cylinder body and the inner wall of the outer cylinder body; the upper cover plate is connected with an air inlet pipe through which compressed and purified air can enter the compressed air depressurization cavity; air-water mixing exchange holes through which air exchange with the dissolved oxygen exchange cavity can be carried out are distributed on the cylinder wall of the inner cylinder body; air-water discharge holes through which air and water inside the compressed air depressurization cavity can be discharged are respectively distributed on the upper cover plate and the lower cover plate; a liquid inlet hole through which liquid can enter the compressed air depressurization cavity is formed at the periphery of the air inlet pipe. By adopting the structure, the high-efficiency air distributor disclosed by the utility model has the advantages that the retention time of air in fermentation liquor is greatly prolonged after the compressed and purified air passes through a distributor, oxygen contained in the air can be sufficiently dissolved into the fermentation liquor after the air passes through the compressed air depressurization cavity and the dissolved oxygen exchange cavity and the uniformity in distribution and good oxygen dissolving effect are achieved.

Description

Efficient gas sparger

Technical field

The utility model relates to a kind of biological fermentation equipment parts, specifically a kind of efficient gas sparger.

Background technology

Existing fermentation equipment is all in fermentation chamber, to pass into pressurized gas to carry out dissolved oxygen, by gas distribution homogenizer, carry out dissolved oxygen, traditional gas distributor comprises a cavity, on cavity, be placed with pore, existing this gas distributor, gas distribution weak effect, is not easy to be evenly distributed, and finally makes the non-constant of dissolved oxygen effect.

Summary of the invention

The technical problems to be solved in the utility model is to provide a kind of being evenly distributed, the efficient gas sparger that dissolved oxygen is effective.

In order to solve the problems of the technologies described above, efficient gas sparger of the present utility model, the outer cylinder body and the inner barrel that is positioned at outer cylinder body that comprise coaxial setting, the upper and lower end face of outer cylinder body and inner barrel is by upper cover plate and lower cover capping, in inner barrel, form pressurized air decompression chamber, between inner barrel outer wall and outer cylinder body inwall, form dissolved oxygen heat exchanger chambers, on upper cover plate, be connected with and can make compression purify air and enter the inlet pipe of pressurized air decompression chamber, on the barrel of inner barrel, be placed with and can carry out with dissolved oxygen heat exchanger chambers the mixing wastewater with air exchange hole of gaseous interchange, on upper cover plate and lower cover, be placed with respectively the air water outlet orifice of the air water discharge that can make in dissolved oxygen heat exchanger chambers, the periphery of inlet pipe is provided with the inlet opening that can enter into pressurized air decompression chamber.

The diameter of described air water outlet orifice is by increasing gradually outside interior.

Spacing between each air water outlet orifice on described same circumference equates.

Adopt after above-mentioned structure, owing to forming pressurized air decompression chamber in inner barrel, the compression with pressure purifies air and enters pressurized air decompression chamber, air suddenly decompression fully mixes increase mixing wastewater with air with fermented liquid, between inner barrel outer wall and outer cylinder body inwall, form dissolved oxygen heat exchanger chambers, in pressurized air decompression chamber, mixed air fully exchanges at dissolved oxygen inverting chamber room air and fermented liquid because pressure reduction enters dissolved oxygen heat exchanger chambers, simultaneously between relief chamber and switch room and be all equally distributed many pores between switch room and outside fermented liquid, make gas flow quick, make thus compression purify air by making the large prolongation of air residence time in fermented liquid after sparger, gas passes through decompression chamber, after dissolved oxygen heat exchanger chambers, make airborne oxygen fully be dissolved in fermented liquid, be evenly distributed, dissolved oxygen is effective.

Fig. 2 is the A-A cross section structure schematic diagram of Fig. 1.

Embodiment

Below in conjunction with the drawings and specific embodiments, efficient gas sparger of the present utility model is described in further detail.

As shown in the figure, efficient gas sparger of the present utility model, the outer cylinder body 1 and the inner barrel 2 that is positioned at outer cylinder body 1 that comprise coaxial setting, the upper and lower end face of outer cylinder body 1 and inner barrel 2 is by upper cover plate 3 and lower cover 4 cappings, the interior formation pressurized air of inner barrel 2 decompression chamber 5, between inner barrel 2 outer walls and outer cylinder body 1 inwall, form dissolved oxygen heat exchanger chambers 6, on upper cover plate 3, be connected with and can make compression purify air and enter the inlet pipe 9 of pressurized air decompression chamber 5, on the barrel of inner barrel 2, be placed with and can carry out with dissolved oxygen heat exchanger chambers 6 the mixing wastewater with air exchange hole 7 of gaseous interchange, on upper cover plate 3 and lower cover 4, be placed with respectively the air water outlet orifice 8 of the air water discharge that can make in dissolved oxygen heat exchanger chambers 6, the periphery of inlet pipe 9 is provided with the inlet opening 10 that can enter into pressurized air decompression chamber 5.

Further the diameter of air water outlet orifice 8 is by increasing gradually outside interior, and the spacing between each air water outlet orifice 8 on same circumference is equated, namely each air water outlet orifice 8 on same circumference is equidistantly arranged.

Its principle is as follows:

The compression with pressure purifies air and enters the pressurized air decompression chamber 5 of efficient sparger, in pressurized air decompression chamber 5, interior air mixes with fermented liquid, on pressurized air decompression chamber 5 tops, there is inlet opening, owing to thering is the compression of pressure, purify air and enter rapid decompression after relief chamber, air enters rapidly switch room the fermented liquid in relief chamber and passes through the outside fermented liquid of inlet opening suction on relief chamber top when the fermented liquid with in relief chamber mixes, the fermented liquid ejecting from relief chamber promotes the fermented liquid of switch room and discharges by base bleed hole, realize circulating of fermented liquid, air enters dissolved oxygen heat exchanger chambers 6 from pressurized air decompression chamber 5 by equally distributed pore, after fully exchanging, the interior air of dissolved oxygen heat exchanger chambers 6 and fermented liquid be discharged to the fermented liquid sparger from dissolved oxygen heat exchanger chambers 6 bottoms, and upwards exhaust, compression purifies air by making the large prolongation of air residence time in fermented liquid after sparger, and gas is fully dissolved in fermented liquid airborne oxygen after by relief chamber, switch room.
