Embodiment 1

[0029] combined with figure 1 , 2 , 3, 4, independent air-lift double-circulation fermentation tank, including tank body 1, insulation layer (2), external circulation device (2.3, 2.4), air intake pipe (3), air intake pipe check valve (3.4) Air distributor (3.1, 3.2, 3.3), internal circulation device (4, 4.1, 4.2, 4.3, 4.4), fermentation temperature sensor (5), feed inlet (6), defoamer inlet (7), Tank cover (manhole) (8), exhaust port (9), pressure valve (10), discharge port (11), heater (12) and viewing window (1.1, 2.7), etc., the equipment is connected to the instrument controller on, which is good for operation.

[0030] In the fermenter, the inverted conical bottom of the tank body 1 is at an angle of 30° to the horizontal plane. The air intake pipe 3 extends downward along the inner wall of the tank body 1 from above, and the lower end is connected to the air distributor (3.1, 3.2, 3.3) at the bottom of the tank. The inlet pipe 4.3 of the internal circulation system ...

Embodiment 2

[0033] Compared with Example 1, the bottom of the tank body can also be arranged in an arc shape, that is, the inverted cone is changed into an arc shape, and the top of the inner circulation pipe is designed to be divided into 3 (or 4) pipes, which are connected to the inner circulation nozzle. Other design is identical with embodiment 1. No more retelling.

Embodiment 3

[0035] Compared with Embodiment 2, the air distributor can be designed to spray air upwards, that is, the air distributor is set upwards, and other designs are the same as in Embodiment 1. No more retelling.

Abstract

The invention discloses an independent air lifting dual circulation fermentation tank, which comprises a tank body (1), a heat insulation layer (2), external circulation devices (2.3 and 2.4), an air inlet pipe (3), an air inlet pipe check valve (3.4), air distributors (3.1, 3.2 and 3.3), internal circulation devices (4, 4.1, 4.2, 4.3 and 4.4), a fermentation temperature inductor (5), a feeding hole (6), a defoamer inlet (7), a tank cover (manhole) (8), an exhaust port (9), a pressure valve (10), a discharge hole (11), a heater (12), observation windows (1.1 and 2.7) and the like. The fermentation tank is connected to an instrument controller through a circuit. The fermentation tank is scientific and reasonable in design, overcomes defects of the prior art, is simple in structure, easy tooperate, low in energy consumption and good in fermentation effect, and has high industrial implementation.

Description

technical field [0001] The invention belongs to the field of engineering machinery, and relates to a fermentation tank used in microbial fermentation engineering, in particular to an independent air-lift double-cycle fermentation tank. Background technique [0002] At present, traditional fermentation tanks mostly adopt the method of mechanical stirring and single-tube ventilation, and the rapid rotation of the stirring paddle is used to break up the air bubbles, carry out uniform gas-liquid distribution, mass transfer, and heat transfer. This method requires strong stirring, so it is necessary The high-power motor drives the stirring device, not only the energy consumption of the fermentation process is too high, but also the equipment is complex and easy to pollute, which affects the fermentation effect. [0003] The air-lift fermenter uses the flow of gas to drive the circulation of the fermentation liquid in the tank, replacing mechanical stirring, which reduces energy c...
