Trap type carbon replenishing device for culturing microalgae of opened pool and carbon replenishing method thereof
A technology of open pool and carbon replenishment, which is applied in the directions of microorganism-based methods, enzymology/microbiology devices, biochemical cleaning devices, etc., which can solve the problem of increasing electric energy consumption of impeller-driven fluids, increasing fluid flow resistance in open pools, and carbon replenishment devices. The problem of low volume utilization, etc., can reduce the fluid flow resistance, prolong the gas-liquid contact time, and reduce the depth.

Embodiment 1
[0038] Spirulina culture is carried out in the track-type culture pool (the most common open pool, referred to as the track pool). The circumference of the runway pool flow channel is 70 meters and the width is 3 meters. The agitator 5 is 4 sets of steel impellers driven by a rotating shaft. Each impeller has 4 blades, which are 90 degrees apart from each other. The blades of adjacent impellers are staggered by 45. degree angle, the rotating shaft is driven by an AC motor and a reducer, and the rotation radius of the agitator 5 is 50 centimeters. The profile of the agitator 5 and the trap type carbon replenishing device 6 is as follows: image 3 . Among them, the carbon replenishment device 6 see figure 2 , including a well-type container 1 , a partition 2 and a gas distributor 3 , and the gas distributor 3 is arranged at the inlet of the culture solution of the well-type carbon replenishment device 6 . Well-type container 1 has a depth of 50 cm, a width of 3 meters (consi...
Embodiment 2
[0045] Others are the same as embodiment 1. The depth of the well-type container is 150 cm, and the thickness is 62 cm; the gap between the lower end of the partition and the bottom of the well-type container is 30 cm, and the thickness of the descending section of the well-type carbon replenishing device is 15 cm. The average depth of the culture medium in the runway pool is 30 cm. Algal cell inoculation density 0.2g (dry weight) / L. The control range of pH was set at 9.7-9.8. The flow rate of the culture fluid in the raceway pool is about 20 cm / s, and the liquid flow rates in the descending section and ascending section of the trap carbon replenishment device are about 40 cm / s and 13.3 cm / s respectively. After continuous cultivation for 6 days, the utilization rate of carbon dioxide in the cylinder was 90%. Stirring power consumption is 1.15W / m 2 .
Embodiment 3
[0047] Others are the same as embodiment 1. The depth of the well-type container is 70 cm, and the thickness is 202 cm; the gap between the lower end of the partition and the bottom of the well-type container is 50 cm, and the thickness of the descending section of the well-type carbon replenishing device is 50 cm. The average depth of the culture medium in the runway pool is 25 cm. Algae cell inoculation density 0.25g (dry weight) / L. The control range of pH was set at 9.9-10.0. The flow rate of the culture fluid in the raceway pool is about 50 cm / s, and the liquid flow rates in the descending section and ascending section of the trap carbon replenishment device are about 25 cm / s and 8.3 cm / s respectively. After continuous cultivation for 6 days, the utilization rate of carbon dioxide in the steel cylinder was 93%. Stirring power consumption is 1.19W / m 2 .
