Problems solved by technology

This sterilization method takes a long time, the sterilization is not complete, at least two sets of equipment are required, and there are still chemical substances in the water, which is not good for microalgae cultivation; in addition, if the reproduction and growth of microalgae are within the optimal temperature range , its reproduction and growth rate are also the largest, but the prior art does not take measures for the above-mentioned optimum temperature range. Therefore, when microalgae are cultured in winter, the seawater temperature is very low, and the yield of microalgae cultured in water of this temperature is very low. Low, when cultivating microalgae in summer, the water temperature of seawater is high, and the culture tank is exposed to strong light in summer, and its temperature will be as high as 40°C, even if it needs a high temperature, Salina will not thrive and grow normally

Abstract

An equipment for culturing microalgae is composed of culturing tank, water supply unit, culture liquid supply unit, air supply unit, CO2 provider, algae liquid collector and artificial light source. Said water supply unit for providing disinfected water consists of water supply pump, water outlet pump, heat exchanger set, water heater, temp-regulating water accumulator, and water source with pump.

Description

technical field [0001] The invention relates to a cultivation device for single-cell microalgae. Background technique [0002] The Patent Office of the China Intellectual Property Office disclosed a patent No. on March 26, 2003 that is 02214168.5, and the name is called a patent document of a culture device for unicellular algae. The device consists of a culture tank, which is connected with a culture fluid supply sub-device, a water supply sub-device, an air and carbon dioxide supply sub-device, an algae liquid collection sub-device and an artificial light source sub-device. This technology has the following disadvantages. Because microalgae are cultivated continuously, a large amount of sterilized water needs to be continuously injected into the culture tank. This prior art uses an ultraviolet sterilizer. This sterilizer has a low rate of killing microorganisms and protozoa that affect the reproduction and growth of microalgae, and the above-mentioned microorganisms and p...
