Embodiment 1
[0026] According to the structure described above, a non-destructive delivery system for algae cells is constructed.
[0027] Algae species: Spirulina platensis.
[0028] Light intensity: The light intensity range is 2000-10000Lx under outdoor conditions.
[0029] Cultivation time: 6 days, algal filaments do not break and die, and the biomass of Spirulina is 1.7-2.5g (dry weight) / L when harvested, which is 40-40% higher than that of pipeline photobioreactors using pump circulation. 70%.
[0030] Pipeline photobioreactor: S-shaped transparent glass reactor with a vertical height of 9.6 meters.
[0031] The diameter of the infusion tube 2 is four times that of the infusion tube 1 .
[0032]When in use: start the water level sensor (8), when it is detected that the water level of the algae liquid in the high level liquid storage tank (1) is lower than the low water level control point, the water level sensor (8) will feed back the signal to the single chip microcomputer (9) th...
Embodiment 2
[0035] The system structure and working principle are the same as those in Embodiment 1.
[0036] When adopting the present invention to cultivate Haematococcus pluvialis, under outdoor conditions, the light intensity range is 2000-10000Lx, and after 10 days of cultivation, the algae cells do not appear to be lost and dead due to mechanical shearing, and the biomass at harvest is 1.3-2.0g (dry weight) / L, which is 63% higher than the biomass of pipeline photobioreactors using pump circulation.
[0037] What is described above is only the preferred embodiment of the patent of the present invention. The device of the invention is easy to manufacture, has low investment cost, and is convenient for carrying out research work on large-scale culture of algae cells and optimization of culture conditions.

Abstract
The invention relates to a lossless frustule conveying system for a sealed type photobioreactor, and particularly relates to a pressure-lifting type lossless frustule circulation conveying system aiming at a sealed type photobioreactor system. The conveying system consists of a high-level liquid storage tank, a low-level buffering tank, a pressure-resisting tank, a pipeline type photobioreactor, an air compressor and an intelligent water level control unit, wherein the high-level liquid storage tank is positioned above the pressure-resisting tank; the high-level liquid storage tank is connected with the pressure-resisting tank through the inlet of the high-level liquid storage tank and the outlet of the high-pressure tank through a conveying tube 1; the low-level buffering tank is positioned secondarily above the pressure-resisting tank; the low-level buffering tank is connected with the pressure-resisting tank through an outlet of the low-level buffering tank and an inlet of the pressure-resisting tank through a conveying tube 2 with an electronic valve; the air compressor is connected with the pressure-resisting tank through a gas conveying tube; the opening of the gas conveying tube is formed at the upper part inside the pressure-resisting tank. The system is lossless for frustule, and the biomass of algae is increased by 70% when being compared with the biomass of the algae when a pump circulation pipeline type photobioreactor is used.
Description
technical field [0001] The invention relates to a closed photobioreactor algae cell non-destructive circulation delivery system, in particular to a closed algae photobioreactor system using a pressure boost type algae cell non-destructive circulation delivery system. Background technique [0002] Microalgae photobioreactors include open culture systems and closed culture systems. The open photobioreactor is the open pond culture system, which is divided into natural lakes and raceway culture ponds. The shape of the track-type breeding pond is mostly oblong, and it is made of bricks and cement concrete. The pond is flat-bottomed and a mixer is installed. The agitator usually adopts the impeller type, the speed is 50r / min, and the flow rate of the algae liquid is maintained at about 20m per minute, so that the water flow can generate a vortex flow to achieve a better mixing effect. The closed photobioreactor is a bioreactor built with transparent materials into different sha...
